Chapter 4 Ground truth 4-1 Selection of survey zones
For the selection of survey zones in Phase I, among 44 zones those are dense with mineral deposits as shown in Table I-5-1-1, the following 20 zones that had little relationship with porphyry copper or copper/gold deposits, epithermal gold deposits, polymetallic vein deposits or SEDEX lead/zinc deposits, all of which had been selected as the targets for the reasons mentioned above, were excluded from the survey. ① Zones dense with the Ordovician sedimentary phosphate deposits: Zones 06 and 25 ② Zone dense with REE (rare earth element) deposits in carbonatite dikes: Zone 20 ③ Zones dense with borate / salts in evaporite : Zones 21, 29 and 30 ④ Zones dense with uranium / vanadium deposits existing in the Cretaceous Yacoraite Formation :
Zones 35, 36 and 37 ⑤ Zones dense with deposits of rare metals such as Nb, Ta and Be in pegmatite: Zones 32, 33 and 40 ⑥ Zones dense with placer deposits: Zones 04 and 19 ⑦ Zones dense with Sn or W deposits that were generated at relatively high temperature and are
expected to have little relationship with porphyry copper deposits: Zones 13, 14 and 44. ⑧ Zones dense with Pb/Zn/Ag vein deposits with Precambrian/Cambrian wall rock before the
forming of SEDEX lead/zinc deposits: Zones 16, 23 and 41 From the remaining 24 zones, 21 zones, or a total of 36 places (of mineral showings), were
selected as zones to be covered by the field survey of Phase I. In Phase II, the following 8 areas were selected. Because these area are thought to have high
potential for the existence of deposits but have been surveyed insufficiently, and future survey are expected to lead to the discovery of new deposits, among potential zones extracted in the evaluation of Phase I.
(1) SEDEX type lead/zinc deposits and volcanogenic massive sulfide deposits 1) El Aguilar area
It is necessary to clarify ore horizons by using lithogeochemistry in El Aguilar mine area including Rio Grande (Zone 13), and stratigraphical division with microfossils such as conodont.
2) Pumahuasi and 3)Santa Victoria area It is also necessary to identify, by the similar method, ore horizons in the east-to-west route
(Zones 2, 3 and 5) connecting from Pumahuasi to Santa Rosa and La Cienaga mineral showings.
4) La Colorada area In La Colorada mineral showing, volcanongenic massive sulfide deposits were discovered by
drilling of Pacific Rim Co., Ltd. It is desirable to identifier the feature of this deposit by analyzing drill hole core sample. Similarly to El Aguilar, lithogeochemical exploration is also required for extraction of ore horizons (Zone 18). Furthermore, Limeca mineral showing are considered as SEDEX type
- 175 -
deposit and it also needs to clear the detail.
(2) Porphyry copper and epithermal type deposits 1) Pancho Arias area
It is hard to say that porphyry type copper and copper/gold deposits have been fully investigated in small-scale stock of the Neogene in the basement rocks located in the extension of volcanic rock arms away from the main body of volcanic rock. Concretely, areas to be investigated are Zone-28. 2) El Pago area
El Pago have been extracted as alteration zones by analysis of the satellite images. It is desirable to acquire the detailed characteristics and distribution of the alteration zone (Zone 47). 3) Rachaite area
It is known that large-scale argillitic alteration zones with base metal, such as Rachaite, Incachule and Pan de Azucar, exist on the wall of annular structure or resurgent calderas. Rachaite in Cornazuli caldera is one of the largest alteration zones in such area, therefore it necessary to identify the detail. 4) Galan area
From the analysis of satellite images, alterations were identified in the candela wall and on its southeast side around Zone-39 and Galan candela. However, this zone has not been sufficiently surveyed yet, so it is desirable to investigate the characteristics and the distribution of alteration and mineralization.

4-2 Survey result 4-2-1 SEDEX/VMS deposits
(1) Aguilar Mountains zone
1) Location and access
The Agular mountains (highest altitude: 5127m) is located from north to south between
smooth plateaus, called Puna and east part mountain range (Cordillera Oriental). The El Aguilar mine
is located almost at the center of this Aguilar Mountains, and about 60km south of Abra Pampa town,
at 23°12′46.3” S. Lat., and 65°40′42.4" W. Long. By driving 47km southward on the paved
National Road 9 from Abra Pampa, Tres Cruces where there is the gate of the El Aguilar mine is
reached in about 20 minutes. Going southward from this gate on a private road constructed over 50km
at the east foot of the Aguilar Mountains leads to the mine office.
2) Content of survey
In the Aguilar mine area, mineralization outcrops of El Aguilar, Oriental, Pirita, Esperanza,
and Rio Grande were surveyed, and in Aguilar mine area periphery, the lower part outcrop of Santa
Victoria Group was mainly surveyed and samples were collected (see Fig.II-4-2-1-1). In order to
clarify petrological, paleontological, geochemical characteristics of SEDEX horizon hosted deposits
and their stratum of hanging/foot walls, and to discover horizon similar to already-known SEDEX
horizon hosted deposits , these samples were subjected to the following various laboratory
examinations.
Observation of thin section of rock: 4
X rays diffraction analysis: 2
Observation of polished section of ore: 1
Ore assay: 1
Fossil identification: 18
Geochemical analysis: 46
To trace horizon hosted deposits, the characteristics of the stratum accompanying SEDEX
horizon hosted deposits were clarified by ASTER images.
3) Mining concessions
Mining concessions are hold in the El Aguilar mine and surrounded area.
4) Past exploration and mining activities
- 177 -
In the Spanish colony age, a missionary who settled down in Yavi tried to recover the silver of
this ore deposits, and constructed a charcoal-fired blast furnace in the Fundicion valley of 7km south
from the Aguilar mine. The same as this registration of the Tapada mine, as the oldest report
concerning ore deposits of Aguilar mountain range; it is filed in the mining ledger of the Argentine
Republic that the mining right was granted to Mr. Manuel P. Pinto in June 1891.
Ore mining was carried out intermittently and on a small scale especially during World War I.
The mine property existed in the names of two men, Mr. Stone and Mr. Bongiovanni of San Salvador
of Jujuy in around 1918. This mine property was transferred to geologists of Saint Joseph Lead for the
name of the company by the end of 1923. Then, this mining right was deposed by the recommendation
of Compania Minera Aguilar S.A. (CMASA) and the Examination No. 23B in 1925. The measurement
records of the mine property and the approval are dated on November 6, 1928. The investment to the
ore deposits exploration including the adit development of 6,798m in length was made in around 1932.
Significant tonnage ore worthwhile to develop a large-scale ore deposits was exposed. The economic
crisis in 1930 delayed the initiation of development in Aguilar mine and operation of the dressing
plant for six years. From the beginning of 1936 up to the present time, the production of ore mining
and lead and zinc concentrate has been continued. In 1980's, the government-run lead company
transferred CMASA to a holding company FLUOR. Actually, this company is in possession of a joint
adventure of COMSUR (66.6%) and Rio Tinto Zinc Company (33.3%).
5) Geology and tectonics
In geology of Aguilar Mountains, the northern part of mountain range bordered by Portillo
Grande valley is shown in a geological map "La Quiaca" with a scale of 1 to 250,000, and the middle
southern part of the mountain range including Aguilar deposits is shown in a geological map “Ciudad
de Libertador General San Martin" with the same scale.
According to these geological maps, Acoite Formation in the upper part of Ordovician system
Santa Victoria Group is distributed in the northern part of the mountain range. The middle southern
part of the mountain range is mainly occupied by Santa Victoria Group (no division). Intrusive rock
bodies called Aguilar and Abra Laite granite that is estimated to have been formed during Cretaceous
and Jurassic Periods are distributed on both sides of east and west of Aguilar deposits. Santa Victoria
Group in the vicinity of Aguilar granite on east side is especially discriminated to Guayoc Chico
Formation (corresponding to the lower part of Santa Victoria Group). All lowlands are covered with
alluvial deposits.
Regarding the central part of Aguilar Mountains, a geological map (Scale: about 1 to 125,000
and made in Aguilar mine) which was inserted in Sureda J.R. (1999) is available.
According to Sureda R.J. (1999), Ordovician system geological stratigraphy consists of
Despensa layer, Padrioc formation, Lampazar formation and Cardonal formation corresponding to the
- 179 -
lower part of the Tremadocian, and Acoite Formation and Sepulturas layer corresponding to the
Arenig, from below. Aguilar quartzite layer or Aguilar Quartzite (Spencer 1950) is a metamorphic unit
in the Cretaceous, and it is assumed that the sedimentary rock of the relevant source rock is Padrioc
formation.
Based on some facts obtained from explorations conducted as part of the geological map-
drawing project of SEGEMAR, Seggiaro R. (in preparation) proposes re-composition of geological
stratigraphy in this zone and is making a new geological map.
Stratum that hosts SEDEX deposits has so far been assumed in between Cambrian uppermost
part and Lampazar formation of the lowest part of Tremadocian formation. However, in the
sedimentary rocks of the Rio Grande valley assumed to be this Lampazar formation, the existence of
the fossil from the lower part of Tremadocian series to their central part was identified. (Martin, 1989
and Rao and Flores, 1998) And the stratum from the lower part to the central part of Tremadocian
series in the east part mountain range is called Saladillo formation (Moya et al, 2000 and Malanca,
2002). For the above reasons, it has been so decided in this area that conventional Lampazar formation
is now called Saladillo formation based on this fossil stratigraphy. Furthermore, it is proposed to
include quartzite (Acenolasa 1968) that was so far included in Padrioc formation in the lower part of
Lampazar formation into Cardonal formation that is further upper position. In this connection, it is
proposed that the conventional Aguilar quartzite in the open-cut mining area in the Aguilar mine be
included in the Cardonal formation because it is positioned in the lower part of the Saladillo
conglomerate.
In addition, because olistostrome is recognized in the Saladillo formation, Seggiaro R. (in
preparation) points out that a tensile fault that acts key role as a pipe of ore-forming fluid of SEDEX
ore deposits exists in the Rio Grande valley and the Despensa valley, and describes as follows. In other
words, “Saladillo formation in the vicinity of boundary with Cardonal formation contains rounded
quartzite and is multi-source conglomerate layer consisting of the fragment etc. of squarish, black
shale. Meanwhile, in the Rio Grande valley and the Despensa valley, rubble of quartzite, olistostrome,
landslides and slumping structure are observed. Olistolith is massive rocks that slipped from the lower
plate side block of the normal fault in the Saladillo formation sedimentary basin. It was caused as an
immediate result of the tensile fault. Economical importance of the discovery tensile fault formed at
the same time as this Saladillo formation's development should be noteworthy. These faults became a
pipe for discharging the ore-forming fluid that turned out to be the SEDEX source of Aguilar deposits
(Pb, Ag, Zn).”
Thus, in spite of this complex geological structure, because a reasonable interpretation of the
field observation result is possible, it was decided in this report, to use this geological map under
preparation (see Fig.II-4-2-1-2) with the consent of Mr. Seggiaro R.

6) Mineralization and alteration
In Aguilar Mountains area, mineral showings such as Candelaria, Pozo Bravo, Rio Grande,
Zarzo, Hueco, Pirita, Oriental, Tapada, and Despensa exist from the north besides El Aguilar and
Esperanza deposits in operation now. Candelaria is a small-scale abandoned mining site and is
composed of galena and zincblende quartz vein with a maximum width of about 10cm hosted in
Acoite formation (confirmed in the first phase survey). Mineral showings other than this Candelaria
are located around the vicinity of both El Aguilar and Esperanza ore deposits (see Fig.II-4-2-1-3).
The El Aguilar deposits are hosted in the meta-quartzite and holnfels in the Cardonal
formation (so far called Aguilar quartzite) with a layer thickness of 200m and are composed of ten
stratiforms of Pb - Zn ore bodies with a scale of an average length of 150 to 1000m, 50 to 300m in
width, and 5 to 80m in thickness. The Aguilar quartzite (according to the result of microscopic
examination of sample A02CX021, metamorphic chart or quartzite which consists of a large amount
of quartz and an small amount of muscovite and a negligible amount of opaque minerals) is formed
from the Cardonal formation that was metamorphosed by the intrusion of Abra Laite granite and
Aguilar granite (according to the microscopic examination of the sample A02CX020, this is
amphibole-granodiorite or Complejo Eruptive Oire with sericite of negligible amount as altered
minerals).
Esperanza deposits in the Saladillo formation (conventional Lampazar formation) consists of
the main manto-type ore body of 350m in total length, 130m in width in the E-W direction, 27°W in
dip and 18m in the maximum, and two ore bodies accompanying the lower part of this stratigraphy.
In the first phase survey, the main ore bodies were observed at the adit 4,577m above sea level
and samples were collected. Microscopic examination of the ore (A01RT059) shows the state of
production of bedded sulfide ore, indicating that the ore consists mainly of zincblende and galena
containing a small amount of chalcopyrite and a very small amount of pyrite. It further presents a clear
lamination structure that almost harmonized with sedimentary structure as long- flaky sericite did.
At about 200m north extension part from the open-cut mining site of this main ore bodies, SEDEX-
type galena and zincblende stratiform ore bodies (about 1.0m thick layer), shale immediately above
that and phyllite quality Slate at the lower part were collected and analyzed (see Fig.II-4-2-1-4). The
geochemical analysis values of three samples are compared, and the elements with the maximum
values were enumerated respectively. The elements with values more than ten times of the minimum
value were shown in bold type.
Upper part shale (A02CX008) :As, Be, Ca, Cr, Cu, P, Sr, V
Stratiform ore bodies (A02CX007) :Au, Hg, Ag, Cd, Fe, Mn, Pb, S, Sb, W, Zn
Slate (A02SX016) :Al, Ba, Co, K, Mg, Na, Ni, Ti

Pozo Bravo is located about 7km north-northwest of Esperanza deposits, most upper-stream of
Quera river on the west side of Aguilar Mountains, and is vein-type lead and zinc deposits hosted in
Acoite Formation. (Sureda,1999)。
Rio Grande, located about 3km northeast of Esperanza deposits and midstream of Rio Grande
valley, is massive pyrrhotite layers with a maximum width of about 20cm, confirmed in the Saladillo
formation (previously Lampazar formation). It is immediately above the stromatolite layer in a bedded
black shale, and with a strike of N30°W and a dip of 15°SW. In the first phase survey, these
mineralized horizons are confirmed at least 150m in length in the inclined direction. Although the
mineralization is similar to that of Mina Esperanza deposits and drilling was carried out, a final
conclusion was obtained that it is not profitable.
Zarzo is located in the most upper-stream of the north side branch of the Rio Grande on the
west side of Aguilar Mountains, about 1km west of Esperanza deposits, and is bedded deposits hosted
in the Saladillo formation. In general, it is considered to correspond to the extension of the west side of
Esperanza deposits with the synclinal structure of N - S direction in between.
Hueco is located about 2km south-southwest of Esperanza deposits and at the most upper-
stream of Rio Grande south branch of Westside of Aguilar Mountains. It is vein-type lead/zinc
deposits hosted in the Cardonal formation. (Sureda 1999)
Pirita, located about 2.5km south of Esperanza deposits, is a mineral showing zone (area of
about 1km2) that is hosted in the Saladillo formation. According to Figure 3 of Sureda (1999), El
Aguilar-Oriental-Pirita is assumed to be a series of bedded deposits. Rincon is one stratiform ore
bodies in this mineral showing zone, and is located about 4km south of Esperanza deposits. Strike and
dip of the ore bodies apparently shows the form of harmonized bedded deposits with the bedding plane
(N10E/50W). The hanging-wall side ore bodies (about 1.0m in layer thickness) are massive quartz's
(Zn grade of about 7%) accompanied by pyrrhotite and zincblende, and ore bodies (layer thickness of
about 1.5m) on the foot side is massive quartzes (Zn grade of about 7%) accompanied by pyrite
impregnation (see Fig.II-4-2-1-5).
As is the case with Esperanza deposits outcrop, geochemical analysis values were compared
with those of the shale of the upper part ore bodies, hanging wall side ore bodies and the lower part
shale, and each element with the highest value was enumerated. The elements with values of ten times
larger than the minimum value were shown in bold type.
Upper part shale (A02CX009) :Al, Ba, Be, K, Mg, Mn, Na, P, Sr, Ti, V
Hanging wall side ore bodies (A02CX011) :Au, Hg, Ag, As, Bi, Cd, Co, Cu, Fe, Mo, Ni,
Pb, S, Sb, W, Zn
Lower part shale (A02CX010) :Ca, Cr
- 184 -
Oriental is located about 1km south of Rincon and about 1.5km north- northeast of El Aguilar
open-cut mining pit, and is stratiform ore bodies (layer thickness of about 2m, with average Pb: 7%,
and Zn: 6%) in the Cardonal formation sandstone which received metamorphism, and is brecciated ore
bodies of average grade of Pb:7% and Zn:6% accompanied by macro crystals of galena and
zincblende (see Fig.II-4-2-1-6).
As is the case with Rincon, the geochemical analysis values are compared with those of
sandstone (according to microscopic examination, altered fine-grain sandstone~siltstone that consists
mainly of quartz, biotite, and feldspar grain) of the upper part of the ore bodies, metamorphic
sandstone of brecciated ore bodies and lower part. Thus, the elements each having a highest value was
enumerated. Further, the elements with values ten times or larger than the minimum value were shown
in bold type.
Upper part sandstone(A02SX006) :Al, Ba, Be, Cr, K, Na, Ni, Sr, Ti
Brecciated ore bodies(A02CX012) :Au, Hg, Ag, As, Bi, Ca, Cd, Co, Cu, Fe, Mg,
Mn, Mo, P, Pb, S,Sb, V, W, Zn
Lower part metamorphic sandstone (A02SX005) :None
Tapada is a small-scale abandoned mining site, located about 3km south of the El Aguilar
open-cut mining site. This is silver-galena brecciated ore bodies harmoniously hosted in the bedding
of the Saladillo formation sandstone of wall rock. There are hanging wall ore bodies with a layer of
0.3m+ thick (altitude 4,719m; see Fig.II-4-2-1-7.) and foot wall ore bodies (altitude of 4,646m)
prospected by drift at the interior of a cross cut of about 20m from the entrances of adits.
Despensa accompanies hammock-like stromatolite with a short diameter of about 20cm in
bedded black shale that admixes limonite breccia thin layer (about 5cm thick) (see Fig.II-4-2-1-8).
Automorphic pyrite(maximum diameter of 2cm)is accompanied scattered in this stromatolite. This
Despensa mineral showings, even of a small-scale, is similar to Rio Grande mineral showings in the
existence of bedded black shale, stromatolite, and iron sulphide etc.
7) Geochemical characteristics
Using samples in Saladillo formation (conventional Lampazar formation) that is horizon
hosted deposits, Discriminant analysis (DA) was carried out as a supervised classification method out
of the multivariate analysis technique, and principal component analysis (PCA) was carried out as an
unsupervised classification method.
The analytical data used are those of 72 samples in total of the cores taken from drilling #3070
hole that captured the SEDEX ore bodies (Refer to Table II-4-2-1-1).

Elements for analysis are Au, Ag, Al, As, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Mo,
Na, Ni, P, Pb, S, Sb, Sr, Ti, V, W, Zn and Hg, 29 elements in total.
Data pre-processing etc, prior to the statistical analysis are omitted because it will be fully
explained later in paragraph 4-3-1(1) "Integrated geochemical analysis".
Discriminant analysis (DA)
The results of grouping by the Discriminant analysis are shown in Table II-4-2-1-2, including
location of each samples collected, characteristics of the appearance and pre-determined grouping
based on the layer level relation with the ore horizon. At the same time, ten variables (logMn, V, logCa,
Cr, Ti, logSb, Na, Mg, logW, and logSr) that are carefully selected as useful for discrimination, and the
coefficient of each variable to three discriminant functions (Y1-2, Y1-3, and Y2-3) which discriminate
between ore horizon (G2) and hanging wall (G1), between hanging wall (G1) and foot wall (G3), and
between ore horizon (G2) and foot wall (G3), are shown. Therefore, the three discriminant functions
are expressed as follows.
Y1-2=-27.90398XlogMn-0.00244XV+16.82988XlogCa-0.23149XCr-55.95001XTi -
13.69739XlogSb-6.84131XNa+19.45493XMg+27.31680XlogW+10.55409XlogSr+ 64.16628
Y1-3=2.47213XlogMn-0.09387XV-8.14173XlogCa-0.18578XCr+49.30599XTi
+10.82742XlogSb-3.95804XNa-3.33270XMg-28.70279XlogW+8.98198XlogSr+ 0.58989
Y2-3=30.37611XlogMn-0.09144XV-24.97161XlogCa-0.41727XCr+105.25600XTi

Theoretical error rate is the highest in between hanging wall (G1) and foot wall (G3), while
the rate between deposits horizon (G2) and foot wall (G3) is lower than between ore horizon (G2) and
hanging wall (G1). That is, though the ore horizon and the footwall can be easily discriminated
comparatively, the hanging wall and the hanging wall are difficult to be discriminated.
Although the discriminant rate shows high value (95.83%), in Table II-4-2-1-3 (referred to
earlier), one shale sample (A01AG49) accompanying quartz minute pulse of ore horizon hanging wall
(G1) is misdiscriminated to be foot wall of ore horizon(G3), while two samples (A01AG66 and
A01AG72) of phyllitic shale in foot wall (G3) of ore horizon are both misdiscriminated to be ore
horizon hanging wall (G1).
Discriminant functions were applied to 46 samples collected on the ground surface, and
grouping to presume a layer level relation with the ore horizon was made. The results are shown in
Table II-4-2-1-3 and Fig.II-4-2-1-9.

According to the table and figure, the following four samples are discriminated to ore horizon
(G2) in this zone.
A02CX007: Collected from galena and marmatite stratiform ore bodies of the north extension outcrop
of Esperanza ore bodies. Upper part shale (A02CX008) has been discriminated to ore horizon hanging
wall (G1), and lower Slate (A02SX016) to footwall of ore horizon (G3). An excellent result has been
obtained as shown in the observation results described in the paragraph of mineralization and
alteration.
A02CX017: Collected as a set with A02CX018 and A02CX019 from mineralization outcrop (Refer to
Fig.II-4-2-1-10) along the mining road about 1km northeast of Oriental. The sample of A02CX017 is
shale (apparently un-mineralized) immediately above the mineralization part. Chlorite and Sericite
alteration part (A02CX018) adjoining this shale are discriminated to footwall of ore horizon(G3).
Silicified rocks (A02CX019) accompanying pyrite dissemination of the lower part are discriminated to
footwall of ore horizon (G1). These are remarkably different from the observation results.
A02CX020: Aguilar granite collected about 1.5km northeast of the Aguilar open-cut mining site.
Since this discriminant function should be basically applied to Santa Victoria Group Saladillo
formation in horizon hosted deposits, it is not appropriate to evaluate granite.
A02SX015: Quartzite of the Cardonal formation collected in the Despensa valley in the southern part.
The function is not appropriate to evaluate for the same A02CX020.
When taking a general view of the discrimination results in the distribution zone of the
Saladillo formation shown in Fig.II-4-2-1-9 (Referred to earlier), footwall of ore horizon (G3) exists
over the area, from north to south, of Rio Grande, Esperanza, Pirita, Oriental, El Aguilar, Tapada and
Despensa. On the other hand, ore horizon hanging wall (G1) is widely distributed on the west side of
the above listed areas that are Esperanza, Pirita, Oriental, El Aguilar and Tapada. It is, however, not
found in the vicinity of Rio Grande in the north and Despensa in the south.
Principal component analysis (PCA)
The principal component analysis starts with the calculation of statistic and correlation
coefficient matrix. The calculated results and output of statistic and correlation coefficient matrix are
shown in Tables 4-2-1-4 and 5 respectively. The principal component load matrix obtained from this
correlation coefficient matrix is shown in Table II-4-2-1-6, the relation between each principal
component and the element in Fig.II-4-2-1-10. In this Table 4-2-1-4, absolute value of load larger than

0.5 is shown in bold type. Further the values with plus sign are indicated in red, and those with minus
sign in blue. (Note that the signs are relative to each other. No contradiction will incur in the
interpretation even if all signs are reversed for each principal component.) The discriminated
cumulative contribution rates of the seven principal components show such a high rate as about 80%.
Since the first four principal components (PC1, PC2, and PC3) make up 60% or higher of the
contribution rate, these four principal components can almost explain the characteristics of these
samples of 72 drilling cores.
Principal component scores of each sample calculated by using the principal component loads
are shown in Table II-4-2-1-7, together with their geological descriptions. The characteristics of the
principal components presumed from principal component load matrix and the relations between each
principal component scores and rock type are shown in Table II-4-2-1-8, and the change of each
principal component scores with depth for each drilling hole is shown in Fig.II-4-2-1-11.
In Table II-4-2-1-8, primary principal components (PC1) accounts for the contribution rate of
23%, and show high correlation with Zn, Cd, Pb, Au, Mn, Sb, Ag, W, and As (in descending order of
absolute load value). The majority of these are ordinary elements of the SEDEX-type ore bodies. As
obvious from Fig.II-4-2-1-11, a higher score at the encounter part with Esperanza ore bodies of
drilling cores (A01AG060~63) is obtained in comparison with hanging/foot walls. Therefore these
elements are considered to be for SEDEX mineralization.
Secondary principal components (PC2) accounts for the contribution rate of 21.4%, and show
a high correlation with Al, Mg, Ti, Cr, Be, K, V, Ni, Fe, and Ba (in descending order of load). This
principal components are presumed to be elements that show a certain kind of characteristics (for
instance, grain size) of clastic rocks because, as is clear in Table II-4-2-1-7, there is a tendency that
arenite indicates a high plus score and muddy rock a high minus score.
Tertiary principal components (PC3) show high correlations with Sr, Na, Ca and K and are
presumed to be elements that show a composition of rocks (especially, feldspar). Fourth principal
components (PC4) show high correlation with Cu, S, and Hg, and are presumed to be elements
associated with the hydrothermal deposit at a comparatively low temperature. Because the
contribution rates of these elements are low at about 10%, it is considered that the influence to the data
variation is low.
8) Characteristics of the satellite image
In ASTER image analysis, false color BGR=147 (hereinafter 147) image identified granite in
Aguilar range as weak red in color, and Ordovician sediments in dark color. The image also identified
sedimentary structure with N-S direction. For alteration mineral identification, ASTER detected Ser-
Geo zone in the boundary area of granite and sedimentary rocks, and Ser-Chl and Chl zone in
sedimentary rocks with N-S in direction.

9) Survey results and comments
(Characteristics of mineralization in Aguilar mine zone)
In Table II-4-2-1-8, primary principal components (PC1) account for the contribution rate of
23%, and they are highly correlated with Zn, Cd, Pb, Au, Mn, Sb, Ag, W, and As (in descending order
of load absolute value). The greater part of these elements is ordinary ones in the SEDEX-type ore
bodies. As obvious from Fig.II-4-2-1-11, it is presumed that these are elements of SEDEX
mineralization, because the high score is clearly shown at an encounter parts (A01AG060-63) of
drilling cores of Esperanza ore bodies when compared with those of hanging/foot walls
In Aguilar Mountain range area, not only in Esperanza deposits which is assumed to be a
typical model of SEDEX deposits, but also in Aguilar deposits, Oriental mineral showings, and Pirita
mineral showings, a high score distribution of these secondary principal components show
geochemically the existence of this SEDEX-type mineralization. However, in Rio Grande mineral
showings located about 3km northeast of Esperanza deposits that are thought to be a similar SEDEX
mineralization, no high score of these secondary principal components has been obtained contrary to
our expectations.
In Aguilar deposits and mineral showings in the periphery, mineralization represented by La
Colorada deposits exists while overlapping with that of SEDEX. However, from the result of this
principal component analysis of 197 samples, no such mineralization is observed in Esperanza ore
bodies. No high score of secondary principal components that indicate SEDEX mineralization are not
identified neither in Rio Grande mineral showings at northeast of Esperanza deposits which were
thought to be SEDEX mineralization in the past, nor in Despensa mineral showings which are similar
to Rio Grande, though of very small-scale, located about 4km southeast of Tapada. Nonetheless, a high
score of this principal component exist in these mineral showings.
·In Aguilar Mountain range zone, it was clarified that SEDEX mineralization contributed not only to
Esperanza deposits which is assumed to be a typical model of SEDEX deposits, but also to Aguilar
deposits, Oriental mineral showings, and Pirita mineral showings.
·In Aguilar deposits and mineral showings in the periphery other than Esperanza deposits, it turned
out that mineralization represented by La Colorada deposits exist while overlapping with SEDEX
mineralization.
·On the other hand, it was found that Rio Grande mineral showings in the neighborhood of northwest
of Esperanza deposits, previously thought to be similar to SEDEX mineralization, had relationship
with mineralization represented by La Colorada deposits rather than with SEDEX mineralization,
contrary to our expectations.

(2) Pumahuasi district
1) Location and access
This district, called PMD (Pumahuasi Mining District), is near the Bolivian border, ranging
from La Quiaca town to Cangrejillo village, which is about 40km south of that town. In this district,
there are many adits of small-scale abandoned mines such as Pumahuasi, La Belgica, Sol de Mayo,
etc., where they once mined the vein deposits of lead, zinc, and barite. These mines are not far from
highways and access is easy.
2) Contents of Survey
According to the existing data, this district is located in the Acoite Formation, the upper layer
of Santa Victoria Group, and therefore, it is highly unlikely that the SEDEX deposit horizon is
exposed. Seven samples were extracted just for reference use (see Fig.II-4-2-1-12).
3) Mining concessions
Mining concessions are widely covered in this area.
4) Past exploration and mining activities
At the beginning of the 20th century: Mining activities were started at Pumahuasi.
1920: Mining was started at Sol de Mayo.
Around 1937: Production at Pumahuasi.
1940 - 1941: Production of 6,000 t lead concentrates At Sol de Mayo.
1978 - 1979: The DGFM (Direccion General de Fabricaciones Militares) carried out the
geological survey, geophysical exploration (electromagnetics, IP, and specific resistivity) and
drilling in PMD. Based on the geophysical exploration, four holes were drilled in Belgica. At
three of them, zincblende impregnation was captured (DGFM, 1980b).
1993 - 1994: Based on a hypothesis that Pb-Zn-Ag mineralization in the PMD could represent
the northern extension of SEDEX-type zinc and lead deposits in El Aguilar, Argentina Mineral
Development S.A carried out detailed geological, geochemical and IP electrical exploration.
The drilling was proposed as the only method to confirm the presence of massive sulfide
deposits (Argentina Mineral Development S.A., 1994).
5) Geology and tectonics
According to the geological map " La Quiaca " with a scale of 1 to 250,000, the greater part of
this district is covered with the alluvial and lake-bottom sediments of Tertiary Pliocene - Quaternary
Alluvial epoch. The Paleozoic Ordovician system, which is exposed mainly at the southeast part,
consists of the Acoite formation of upper layer of Santa Victoria Group. Ordovician system is exposed
- 206 -
scatteredly, and its weathered alteration is remarkable, and therefore, the detailed structure is not clear
(see Fig.II-4-2-1-12 referred to earlier).
6) Mineralization and alteration
In the Pumahuasi district, they once mined the deposits on a small scale, such as Pumahuasi,
Sol de Mayo, La Belgica-Alejandro etc. These deposits were surveyed in the 1st year of the project.
The Pumahuasi deposit consists of two main veins that are called Pumahuasi Viejo and Pumahuasi
Nueva. The ores collected from the place near the ground surface are cerussite, anglesite and limonite.
In the lower part, galena is dominant (Pb:14%, Zn:1%). Pb starts to decrease at a depth of about 250m,
and accompanies Zn of 35% at maximum at a depth of around 350m. The deposit is located along the
river flowing in flat Pampas, and its only remaining structures are a vein trench, two vertical shafts, a
building foundation, and a large-scale debris-piling site.
At the Sol de Mayo deposit, two almost parallel veins about 250m apart are observed;
"Matadero" in the northern part and "Sol de Mayo" in the southern part. As underground mining was
carried out at these veins and they are submerged in water now, it is impossible to investigate.
Matadero vein has a total length of 120m, and the main vertical shaft reaches the depth of 150m. The
most dominant mineralization is shown in zincblende and galena followed by chalcopyrite.
La Belgica deposit and Alejandro deposit adjoin mutually, and both veins run almost in the E-
W direction, which is perpendicular to stratum strike (the N-S direction). Main minerals are galena,
zincblende, iron pyrite, chalcopyrite, limonite, cerussite and anglesite. Barite, ankerite, quartz, and
limonite exist as gangue mineral.
7) Geochemical characteristics
The discriminant functions were built on the basis of the analytical data of 72 drilling core
samples of the Aguilar district, and they were applied to seven samples collected and analyzed in this
district. The discrimination result is shown in Table II-4-2-1-9 and Fig.II-4-2-1-13. According to the
table and figure, all the seven samples come from the bedded shale belonging to the Acoite Formation
of upper layer of Santa Victoria Group, or bedded shale accompanied by a thin layer of sandstone. In
the discriminant analysis result, they are classified into the category of the hanging-wall layer of
mineralized horizons.
Two samples from the bedded shale in the waste of Pumahuasi mining site and the bedded
shale/sandstone from the northwest of southern part of Morado Mountain are discriminated to the
deposit horizon foot wall (G3). Five other samples are discriminated to the semi-foot wall (G1).
8) Characteristics of the satellite image
ASTER 147 outlined upper Ordovician sediments with N-S direction and Quaternary, which
- 208 -
covers Ordovician. Mineral identification detected Chl zone of elongated shape in the southern part of
survey area.
(3) Santa Victoria Mountain area
1) Location and access
This area is located in the Agua Chilca village at the western foot of the Santa Victoria
Mountains. The route starts from La Quiaca town and goes on State Road No. 5, on unpaved road
along the Casti valley, and on State Road No.69. It takes about one hour by car to reach there.
The Santa Rosa abandoned mine is located at S. Lat. 22°37' 54 " and W. Long. 66°2' 55". It is
located about 50km southeast of La Quiaca and about 40km east of the Pumahuasi mineral showings.
The route starts from La Quiaca town and goes on State Road No. 5 , the unpaved road along the
Quobrada de Casti, then to Agua Chilca, a colony at the western foot of Santa Victoria Mountains. The
place of mineral showings is then reached by going on State Road No. 69 by way of Abra del Condor.
It is about one hour and 45 minutes’ drive.
La Cienaga abandoned mine is located about 20km south-southwest of Santa Victoria town,
about 25km east of the Santa Rosa mineral showings and about 70km southeast of La Quiaca. It takes
about 2 hours to reach the Cienaga from the Santa Rosa by going on a bad mountain path over the
altitude of 4,000m. The access is very bad.
2) Contents of survey
The area that crosses the Santa Victoria Mountains with remarkable structure of N-S direction
was surveyed. This area stretches along State Roads Nos. 5-7, and No. 69. Samples were collected
mainly from Santa Rosita layer, i.e., the outcrop of the lower part of Santa Victoria Group. (see Fig.II-
4-2-1-14.). In order to discover some deposit horizons similar to the SEDEX horizon hosting deposit
whose characteristics on petrology, paleontology and geochemistry are already known, these samples
were subjected to laboratory examinations as follows.
Observation of thin section of rock: 5
Diffraction X ray analysis: 3
Observation of polished section of ore: 2
Ore assay: 3
Fossil identification: 7
Geochemical analysis 104
Moreover, in order to track the horizon hosted deposits, the characteristics of strata with
SEDEX horizon hosted deposits were clarified by ASTER images.

3) Mining concessions
Mining concessions are covered in old abandon mine area only.
4) Past exploration and mining activities
None
5) Geology and tectonics
According to the geological map " La Quiaca " with a scale of 1/250,000, the geological
stratigraphy of this district is as follows in the ascending order of depth. The Proterozoic Puncoviscana
formation, the Lizoite formation (which is the lower layer of Meson Group of the Middle and Upper
Cambrian), the Campanario formation (which is the middle layer of this Group), the Chalhualmayoc
formation (which is the upper layer of Lizoite), the Santa Rosita formation (which is the lower layer of
the Santa Victoria Group of the late Cambrian to the Middle Ordovician), the Acoite Formation (which
is the upper layer of this Group), the Mecoyita of the late Ordovician, the Lipeon formation of late
Ordovician to the Lower Devonian, Pirgua sublayer group from the Lower Cretaceous to the Upper,
the Santa Balbuena sublayer of the Palaeogene, furthermore, the conglomerate layer of the Pliocene to
the Pleistocene. As intrusive rocks, the granites of the Lower and the Middle Cambrian and the syenite
of the Paleocene etc. are observed.
Among these rocks, the rocks before the Palaeogene are controlled by the fault and fold
configuration in the direction of NNE-SSW~NE-SW. Especially the Santa Rosita layer of Santa
Victoria Group, which is considered to be important as the SEDEX horizon hosting deposit, is
developed and distributed in the extension of this direction, and it is often repeatedly exposed by the
thrust fault (see Fig.II-4-2-1-14 referred to earlier).
In this survey, Rossodus tenuis (Miller and 1980) and Drepanoistodus sp. were identified.
They were found to be mixed with gastropods and brachiopods in the Santa Rosita layer limestone of
the lower layer of Santa Victoria Group near Santa Victoria town. It proved to be Tremadocian Deposit
(absolute age, about 487 - 489 m.y.) of the lower layer of widespread Ordovician system (see Fig.II-4-
2-1-15).
6) Mineralization and alteration
In the Santa Victoria Mountains, there are Pb-Zn-Cu ore deposits such as Santa Rosa, La
Cienaga etc. that were explored on a small scale. These deposits were surveyed in the first year of the
project. The survey results in the first year are extracted as follows.
Santa Rosa
The abandoned mining site shows an inverted-L shape where a 60-m trench in the N50°E
- 212 -
direction crosses a 50-m trench in the N30°W direction. As weathered erosion is significant, the
conditions of the existence of veins in the abandoned mining site are unknown. According to
SEGEMAR (1999), results of mineralization are galena, a small amount of zincblende, chalcopyrite,
and their oxidation mineral. Gangue minerals are only barite and quartz. Silicification and
kaolinization are observed at the edge of wall. The reserve is calculated to be 27,000t (Pb:4%,
Zn:3.5%).
La Cienaga
Three entrances of adits were confirmed at two on the south side and one on the north side of
the valley. With consideration given to the fact that all adits show similar direction of almost N-S and
all veins show similar inclination of westward, it is assumed that these adits were used for mining one
plate of the vein. In an adit on the south side along the valley, stringers (about 20 cm wide) of barite
accompanied by a small amount of malachite are exposed in a small range.
7) Geochemical characteristics
The discriminant functions were built on the basis of the analytical data of drilling core
samples of the Aguilar district, and they were applied to 104 samples that were collected and analyzed
in this district. The discrimination results are shown in Tables 4-2-1-10 and Fig.II-4-2-1-16. According
to the table and figure, the following four samples are discriminated to the deposit horizon (G2) in this
district.
A02CX070: Bedded black shale found in alternation of mica-sandstone and black shale at the west
foot of anticlinal structure at the western part of La Cienaga deposit (see Fig.II-4-2-1-17). Incidentally
the sandstone of mica (A02CX069) is discriminated to the deposit horizon foot wall (G3).
A02CX086: Bedded black shale found along the road about 5km west southeast of La Cienaga deposit
(see Fig.II-4-2-1-17 referred to earlier). The black shale (A02CX085) of the eastern outcrop is
discriminated to the deposit horizon-hanging wall (G1). The fine-grain sandstone of mica of the
western outcrop (A02CX087) is discriminated to the deposit horizon foot wall (G3).
A02CX092: Bedded shale found in alternation of mica-sandstone and bedded black shale, which are
exposed about 2km further west of the above-mentioned A02CX086 (see Fig.II-4-2-1-17 referred to
earlier). Incidentally the sandstone of mica (A02CX091) is discriminated to the deposit horizon foot
wall (G3). The bedded shale (A02CX090) found further eastward of the alternation outcrop is
discriminated to the deposit horizon-hanging wall (G1).

8) Characteristics of the satellite image
ASTER 147 indicates the distribution of sedimentary rocks with N-S direction of brown to
light brown in color. Mineral identification detected many of Ser-Goe zone and Kao-Ser zone in
western part of survey area, these alterations are distributed concordance with sedimentary structures.
(4) La Colorada mine area
1) Location and access
La Colorada abandoned mine is located at S. Lat. 23°38' 52.6'' and W. Long. 66°17' 26.9'', at
an altitude of 3,577m (abandoned site for open-cut mining at the east side). It is about 65km north of
the San Antonio de los Cobres town. It takes about 1.5 hours by car from the town to the site. The
routes from the town are National Road No. 40 and State Road No. 38. The distance is 68km to be
covered in about 1.5 hours. The roads allow high-speed driving, though not yet paved.
According to Mendez y Mendez (2001), the Limeca mining site is located at S. Lat. 23°41' 09"
and W. Long. 66°20' 35'', and at an altitude of 3,711m. It is located 6km from Cobres colony, and is
reached by driving south for several kilometers on State Road No. 38, branching westward, then on
foot.
2) Contents of Survey
The deposit horizon and hanging/foot walls of La Colorada deposit are considered to volcanic
massive sulfide deposit (VMS). In order to clarify petrological, mineralogical and geochemical
characteristics of the deposit, drilling cores kept at Mines Bureau of Salt State were examined in detail
and some samples were collected (see Fig.II-4-2-1-18). The collected samples were subjected to
laboratory examinations as follows.
Observation of thin section of rock: 22
X rays diffraction analysis: 20
Observation of polished section of ore: 15
Ore assay: 15
Geochemical analysis 35
Further, in order to track a north-south extension of La Colorada deposit, La Colorada
abandoned its neighborhood and mine were surveyed and samples were collected. Mendez y Mendez
(2001) indicated presence of SEDEX-type mineralization in the Limeca mining site, where detailed
examination of the outcrop along the river was made and samples were collected (Fig.II-4-2-1-19).
The collected samples were subjected to laboratory examinations as follows.

4) Past exploration and mining activities
1955-56: In La Colorada deposit district, Compana Minera Aguilar carried out the geological
surveys, physical exploration and drilling (nine holes, a total of 800m)
1988-1990: The Army Arsenal (FM) carried out the geological surveys, geochemical
exploration and drilling (two holes, a total of 300m).
1992: Pacific Rim Co., Ltd. obtained a mining right.
1993-1999: Pacific Rim Co., Ltd. carried out the satellite image analysis, airborne magnetic
surveys, EM, CSAMT, TEM, TFM, and drilling (five holes, a total of 1,086m)
As a result, massive sulfide deposits of three horizons were captured. It was estimated that
reserves (demonstrated + inferred) were 12.5 million t. They judged that there was not sufficient
economic feasibility, and withdrew.
Mendez y Mendez (2001) introduced the Limeca exploration site and indicated the possibility
of a SEDEX deposit.
5) Geology and tectonics
According to the Salta geological map with a scale of 1/500,000, the geological stratigraphy of
this district is in the ascending order of depth as follows: the Puncoviscana formation of the
Precambrian, the Meson Group of the Cambrian, Las Vicunas layer and Falda Cienaga formation of
the Lower and Middle Ordovician, the Payogastilla Group of the Neogene, and talus cone sediment of
the Recent. As intrusive rocks, Oire eruption compound rocks of the Middle Ordovician or the
Hornillos syenite or Rangel granite of the Lower Cretaceous are distributed (see Fig.II-4-2-1-19
referred to earlier).
La Colorada deposit, which is called volcanic massive sulfide deposit (VMS), is located in the
Ordovician system. Generally the Ordovician system of this neighborhood constitutes the fold of
various order, and its schistosity is remarkable. Moreover, thermal metamorphism causes hornfels
- 223 -
under the effect of the Cobres granodiorite belonging to the Oire eruption compound rocks of the
Middle Ordovician which adjoins the west side.
On the other hand, the Limeca exploration site by Mendez y Mendez (2001) is located in the
above-mentioned Ordovician system range. The findings are described by Mendez y Mendez (2001)
as follows.
" In the Limeca exploration site, Sierra de Cobre mountain area is formed by Santa Victoria
Group of the Ordovician period. The Group consists of slate, uartzite, quartz-biotite schist, etc. Except
stocks or vein of Neogene quartz porphyry andesite, there are no volcanic rocks in Ordovician
sediment known. "
6) Mineralization and alterations
According to the results of exploration made by Pacific Rim Co., Ltd, it seems that three
sulfide deposit horizons were captured from detailed geological surveys of the ground surface and
drillings. The ground surface consists of gossans. It shows a vein-like shape at a glance. Sulfide
minerals appear 3m under the ground surface and downward. Observations of drilling cores taken by
Pacific Rim Co., Ltd., show massive sulfides of pyrrhotite slightly accompanied by iron pyrite and
chalcopyrite, part of which fills the brecciated parts of the wall rock. According to Mayon et al. (1999),
primary sulfides confirmed with samples at drilling are pyrrhotite, zincblende, chalcopyrite, galena,
magnetite, loellingite, natural bismuth, cassiterite, tetrahedrite and electrum.
According to the 1st year survey, microscopic examination of two samples of volcanic rocks
revealed the following. One sample was metamorphic rocks originating in muddy rock and is
composed of biotite, muscovite, and anthophyllite. It is assumed that another sample is holocrystalline
equigranular texture, consisting of alteration minerals such as clinopyroxenes, brown amphibole,
sericite, smectite, and chlorite.
In the 2nd year survey, 15 samples of drilling cores were collected, and microscopic
observations of ore grinding slices were made. According the results, the ore body mainly consists of
pyrrhotite, and accompanies chalcopyrite, zincblende, arsenopyrite, galena, and ilmenite. It also
accompanies a trace of bismuthinite, natural bismuth, and electrum. The presence of these minerals
was confirmed by the results of chemical analysis of these samples, showing that the values were all
high for S, Fe, Cu, Zn, As, Pb, Ti, Bi, Au and Ag.
Rocks of the hanging wall (including the gangue rock in an ore horizon) and the footwall of
deposit horizon are mostly biotite-muscovite schist. The footwall is partially spotty biotite granodiorite
(spotty lay rock or spotty, fine lay rock under microscopic examination). The diffraction X-ray
analysis (see Table II-4-2-1-11) of these rock samples revealed commonly quartz, chlorite, and sericite.
There is no significant difference between the hanging wall (including the middle stones in an deposit
zone) and the footwall of deposit horizon. Using samples of hornfelsized shale, sandstone, and
- 224 -
hornfelsized phyllite sandstone at the Rio de Cobres valley in the southern edge of in La Colorada
deposit, the diffraction X-ray-analysis revealed commonly quartz, chlorite, and sericitein the same
manner as the drilling cores.
On the other hand, Mendez y Mendez (2001) described the mineralization of the Limeca
exploration site as follows.
"Mineralization occurred in the sedimentary rock of the Ordovician and the deposit is
composed of pyrite, pyrrhotite, zincblende, leaf-like graphite, chalcopyrite, zircon, apatite, titanite,
rutile, and tourmaline. Moreover, the substrate is recrystalized, consisting of the quartz, sericite, calcite,
epidote, and barite. "
7) Geochemical characteristics
Drilling cores of five holes that captured VMS deposit (see Fig.II-4-2-1-18 referred to earlier)
were used in order to examine geochemical characteristics of deposit horizon and the hanging/foot
walls. Principal component analysis and discriminant analysis were conducted in the same manner for
samples from Aguilar Mountain area.
Analytical data obtained from 35 samples of drilling cores of five holes were used. The
geological description etc. of 35 samples is shown in Table II-4-2-1-12, and the analysis results are
shown in Table II-4-2-1-13. Analyzed elements are Au, Ag, Al, As, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe,
K, Mg, Mn, Mo, Na, Ni, P, Pb, S, Sb, Sr, Ti, V, W, Zn and Hg, 29 in total. The pre-processing of the
data before the statistical analysis will be described in detail in 4-3-1 (1) " General geochemical
analysis" and is omitted here.
Discriminant analysis (DA)
Results of grouping obtained by the discriminant analysis are shown in Table II-4-2-1-14,
together with the pre-determined grouping base on drilling hole number, sample collection depth, and
layer level relationship with horizon. The following variables and coefficients were carefully selected
as useful for discrimination and are shown in the table. They are four variables (logFe, logNi, logCu,
and logCo), and the coefficient of each variable for three discriminant functions (Y1-2, Y1-3, and Y2-3).
These functions discriminate between deposit horizon (G2) and hanging wall (G1), between hanging
wall (G1) and foot wall (G3), as well as between deposit horizon (G2) and foot wall (G3). Therefore,
three discriminant functions are expressed as follows.
Y1-2=-53.33277XlogFe+25.16985XlogNi+3.29869XlogCu-10.03044XlogCo-64.16628
Y1-3=15.89377XlogFe-4.14167XlogNi+4.97457XlogCu-4.80755XlogCo-12.50252
- 225 -
Y2-3=73.22653XlogFe-29.31151XlogNi+1.67588XlogCu+5.22289XlogCo-59.80429
The theoretical error rate is highest among the hanging wall (G1) and the foot wall (G3), while
the rate between the deposit horizon (G2) and the footwall (G3) is lower than the rate between the
deposit horizon (G2) and the hanging wall (G1). The results are similar to that of the discriminant
analysis of 72 drilling core samples collected from Aguilar Mountains zone. In other words,
discrimination between the deposit horizon and the foot wall is relatively easy, while discrimination
between the hanging wall and the foot wall is difficult.
Although the discriminant rate is high (94.29%), errors occur sometimes as shown in Table II-
4-2-1-14 (above). One sample (A02PZ205) of chlorite - biotite - muscovite schist of deposit horizon
foot wall (G3) is misjudged as the deposit horizon hanging wall (G1). Another sample (A02PZ507) of
biotite - muscovite schist of the deposit horizon hanging wall (G1) is misjudged as the deposit horizon
hanging wall (G3).
Principal component analysis (PCA)
The principal component loading matrix obtained from principal component analysis is shown
in Table II-4-2-1-15. In this table, the load of absolute value larger than 0.5 is bold-faced. The positive
and negative values are shown in red and blue, respectively. The cumulative contribution rate of four
principal components extracted is as high as about 84%. It seems, therefore, the 35 samples that
captured La Colorada deposit can be characterized by these four principal components.
Table II-4-2-1-16 shows the principal component score of each sample calculated using the
principal component load, as well as the layer level relationship with the deposit horizon. Table II-4-2-
1-17 shows the characteristics of principal components that are estimated as to how the rock qualities
etc. are related to the principal component loading matrix and score of each principal component.
The discriminant functions based on analytical data of drilling cores taken from Aguilar area
were applied to 46 samples collected in this district and analyzed. The discrimination results are
shown in Table II-4-2-1-18 and Fig.II-4-2-1-20.
8) Characteristics of the satellite image
Because of widely covered clouds, ASTER image quality is not enough for interpretation, but
BGR 147 identified N-S direction sedimentary rocks. Mineral identification image detected Kao-Ser
zone and Jar-Goe zone in the middle to southern part of survey area.

4-2-2 Porphyry copper and epithermal type deposits (1) Pancho Arias area 1) Location and access
The Mina Pancho Arias is located at lat. 24º16’ S, long. 65º51’ W, about 3,500 m above sea level. It lies 75 km direct northwest of Salta. This area is administratively under Departamento de Rosario de Lerma in Salta Province. The area is reached by going up to north on a rough road along Río Rosario diverging from Puerta Tastil where is located 35 km from Salta, via National Road 51, which runs from Salta to San Antonio de los Cobres. It is possible to travel all the way by a 4-wheel-drive vehicle. (Fig. II-4-2-2-1-1 Location map of the Pancho Arias area)
2) Mining concessions The following concessions are established in and around the Mina Pancho Arias:
• Mining license No. 4799 (holder: Lapacha Minera SRL) • Exploration licenses Nos. 15602-1996, 15603-1996 and 15757-1996 (held by Minera Argentina Gold SA) The mining license is located around the old workings in the Mina Pancho Arias (also called the Mina Vizcacheral). In a place west of this area, three exploration licenses are located in a line from south to north. No other concessions are established in this area (in the Las Burras and the Incahuasi prospects, there is no concession at present). Fig. II-4-2-2-1-2 shows the situation of concessions in the Pancho Arias area.
3) Past exploration and mining activities • Around 1700, some prospectors who visited with the Jesuit missionary discovered the mineral showings. (There are some old workings, which seem to date from that time.) • In 1950’s and 1960’s, a series of exploration was carried out by the Delegacio’n General de Fabricaciones Militares (DGFM). • From 1972 to 1975, the exploration was carried out according to the United Nations NOA I program (DGFM set up a Reserva and called it as the Vizcacheral). The works included topographic survey (Scale: 1 to 2,500), geochemical survey (stream sediments), geophysical survey using the IP method (total line length: 19.2 km), electromagnetic survey (line length: 5 km) and drilling (10 holes totaling 1,716 m). As the result, porphyry copper-molybdenum deposits with ore reserves of 230 million tons at 0.035 % Mo were caught (regarding Cu mineralization, a copper dissemination body was caught in a drill hole at a depth from 50 m. The average copper grade at 32 m length was 0.30 % Cu. The highest copper grade reached to 1.45 % Cu). Based on the results of the IP and electromagnetic survey, the anomaly probably due to a sulfide body was detected at a depth of about 300 m. • From 1995 to 1997, an exploration program (mainly comprising geological survey, geochemical survey, geophysical survey using the IP method) was made by Aranlee Resources. Aranlee Resources said that the mineralization seemed to be of the typical porphyry Cu and Mo type. According to a report
- 236 -
of Aranlee Resources, mineralization occurs in the quartz stockwork zone hosted by dacite porphyry. The central part of the deposits lies in the potassic alteration zone, and it is surrounded by phyllic/argillic alteration zone (consisting of quartz-sericite-clay minerals, and sulfide minerals). The propylite zone occurs at the outermost of them. • In 1998, Mansfield Minerals carried out an exploration program (geological survey, geochemical survey, geophysical survey using the IP method, six trenches of 870 m in length and four drill holes) in the Las Burras prospect (8 km south of the Mina Pancho Arias). • From 1997 to 1999, Mansfield Minerals carried out an exploration program (geological survey, geochemical survey, geophysical survey using the IP method and 6 trenches of 860 m in length) in the Incahuasi prospect (13 km south of the Mina Pancho Arias).
4) Geology and geologic structure Based on the Mapa Geológico de la Provincia del Salta at a scale of 1 to 500,000, the
geology around the mineral showings, is composed of the upper Precambrian Puncoviscana group sedimentary rocks (greywacke, shale and sandstone; partly presenting the green schist facies due to the weak metamorphism), the lower Cambrian, Meson group (shale, sandstone and conglomerate), the Santa Victria group (sandstone), and the Cambrian granitic rocks (Tastil granite). The Tertiary acidic intrusives occur in these sedimentary rocks and granites. The acidic intrusives are generally small (about 5 km in length along the major axis), made up of dacitic, audesitic, monzonitic, and dioritic composition. About ten acidic bodies are exposed on the surface in this area, occurring for 50 km from south to north. The acidic intrusives are of Miocene age (15 to 13 Ma). (Fig. II-4-2-2-1-3 Geologic map of the Pancho Arias area)
5) Mineralization and alteration The Mineralization and alteration of the Mina Pancho Arias occur in monzonite or dacite
porphyry of the upper Miocene (age determination was made by the survey last year; a result of 15.4 ± 0.3 Ma was obtained), and in the Precambrian sedimentary rocks near the porphyry. The known ore deposits have of porphyry copper-molybdenum type mineralization. Sulfide minerals such as chalcopyrite, chalcocite, covellite, galena and molybdenite were reported. The ore deposits accompany several hydrothermal alteration zones. The most important of them is the potassic alteration zone (biotite-potash feldspar) within the area whose major axis from the central part is several hundred meters, which is in turn surrounded by a propylite alteration zone (accompanied by chlorite - epidote - calcite and pyrite). Inside and around the propylite zone, a phyllic - argillic alteration zone (quartz - sericite - clay mineral) is distributed. There is mineralization of mainly molybdenite and a small amount of chalcopyrite and pyrite partly in the potash alteration zone, while mainly pyrite is mineralized in the phyllic - argillic alteration zone. Mineralization of these sulfide minerals present dissemination and form stringers.
- 239 -
In the south of the Mina Pancho Arias, porphyry copper/gold mineralization is observed in Mozonitic porphyry in Las Burras. Dissemination - stockwork of quartz - tourmaline - magnetite containing Cu and Au (±Mo) is distributed with silicification and sericitizatio. As sulfide mineral, pyrite, chalcopyrite and chalcocite are observed. ineralized alteration is not found remarkably on the ground surface, and only weak propylitization is observed generally.
In two places, which are about 3 km away from each other (Incahuasi Norte and Incahuasi Sur) in Incahuasi, porphyry copper/gold mineralization is observed in monzonitic porphyry of Tertiary Miocene. Mineralization of quartz - tourmaline - magnetite of the stockwork type is accompanied by silicification, sericitization and chloritization here. In stockwork, sulfide minerals, such as pyrite, chalcopyrite and chalcocite, and rarely native gold are observed. According to the results of the investigation of Mansfield Minerals Co., Ltd., quartz and tourmaline stringers located in the peripheral zone accompany places with the largest amount of gold.
6) Characteristics of the satellite image In the Mina Pancho Arias, three main alteration zones can be identified from ASTER image
analysis. As a result of identification of altered mineral with the Isograin Model used, it was found that an alteration zone composed of chlorite - epidote spreads in the area of 2.0 km x 1.5 km near an old mine (Socabón). Inside it, an alteration zone mainly made up of sericite and kaolin and accompanied by a small to trace quantity of goethite and jarosite is observed, and forms alteration zoning. Northwest of this old mine, there is distribution of an alteration zone mainly consisting of a combination of chlorite and epidote. Inside or around these alteration zones, it is observed that alteration zones mainly composed of small-sized sericite are output sporadically.
South of Mina Panch Arias, alteration zones have been mapped out in several places from ASTER image analysis. Although no large alteration zone is found in Las Burras, in and around Incahuasi, located south of it, alteration zones with the long axis of 1 to 3 km and made up of sericite and chlorite are distributed in several places. (Fig.II-4-2-2-1-4 ASTER image analysis of hydrothermal alteration zones in the Pancho Arias area)
7) Survey results Following the investigation of Phase I (number of collected samples: 12), geological surveys
were carried out in three zones: (i) Mina Pancho Arias, (ii) Las Burras and (iii) Incahuasi zones. In addition, a drilling core, which was made by DGFM and is kept by the Mine Department of Salta State, was surveyed. The number of collected samples is 89 in total. (The breakdown of analyses and tests is as follows: 40 geochemical analyses, 6 ore analyses, 2 whole rock analyses, 50 X-ray analyses, 18 rock thin-section assessments and 4 ore polished thin-section assessments.)
In the Mina Pancho Arias, with an old mine and pits in three places aligned in the N-S direction as the primary object, outcrops of a potash alteration zone in monzonitic porphyry, drilling holes and trenches were also investigated. Objects of the exploration of the old mine and pits were monzonitic
- 241 -
porphyry which was subjected to silicification, argilliization, or potash alteration with biotite as the main body; and quartz stringers and network vein zones around it which exist in sandstone/shale belonging to Puncoviscana complex. In and around the quartz veins, silicified sulfide minerals (partly changed to limonite due to weathering) with pyrite as the main are observed. It is seen that strongly silicified parts contain tourmaline. Parts with dissemination of copper mineral were found, although partially. The following results of analysis were obtained from samples collected in a trench northwest of the old pit: Au 2.00 g/t, Ag 407 g/t, Cu 0.01%, Pb 1.91%, As 0.83% (A02RF018).
According to results of X-ray analysis of samples collected in this zone, a potash alteration zone mainly made up of quartz, biotite and potassium feldspar is observed within the area with the long axis of about 1 km (short axis of several hundreds meters) whose center is the place located about 800 m northeast of the old pit where monzonitic porphyry is exposed. Other potash alteration zones are partly observed on a small scale. In this zone, there is output of phyllic - argillic alteration zones characterized by a combination of quartz - sericite - kaolin and containing a small to trace quantity of goethite and jarosite. Two phyllic - argillic alteration zones presenting a long and narrow form principally extending in the NE-SW direction are output in parallel near the old mine. In several places, there is distribution of small phyllic - argillic alteration zones with the long axis of several hundred meters northwest of the old pit in the Mina Pancho Arias. Surrounding these alteration zones, propylite alteration zones made up of chlorite and epidote are distributed.
Based on results of ASTER image analysis and site surveys, characteristics of hydrothermal alteration zones can be summarized as follows: (1) Alteration zones can be divided into three kinds according to the combination of minerals: potash alteration zones, phyllic - argillic alteration zones and propylite alteration zones. (2) Potash alteration zones occupy a small part of the inside of propylite zones. Phyllic - argillic alteration zones are spreading mainly in the NE - SW direction, and appear to be controlled by cracks. (3) Porphyry copper/molybdenum (gold) mineralization is output in the area where potash alteration zones and phyllic - argillic alteration zones are distributed. (4) These alteration zones are located in Precambrian sedimentary rocks around monzonitic porphyry of Miocene as the center.
For the drilling core made by DGFM, parts where copper mineral and molybdenum mineral were observed were mainly investigated, and a small quantity of samples was collected. Mineralization is found in monzonitic porphyry, and sandstone and shale in Puncoviscana complex. In Drilling Hole P4, stringers of quartz and carbonate mineral develop in parts with strong silicification, and sulfide minerals with pyrite and a trace of chalcopyrite as the main were observed in those stringers. Results of analysis of this part were Au 0.02 g/t, Ag<1 g/t and Cu 0.42% (Sample A02RF002). In Drilling Hole P7, parts containing stringers of pyrite and molybdenite in monzonitic porphyry were observed. Results of analysis of this part were Au and Ag below the limit of detection, Cu 0.01% and Mo 0.22% (Sample A02RF005). As a result of X-ray analysis of these drilling samples, small to trace quantities of sericite and potassium feldspar were detected with quartz and biotite as the main. (Fig. II-4-2-2-1-5 Survey results in the Mina Pancho Arias)

In Las Burras zone, trenches excavated in N-S and E-W directions in four places and alteration zone outcrops are distributed in valleys between mountains rising about 3,700 m above sea level. Parts where quartz stringers or network veins accompanying copper mineral in monzonitic porphyry developed were observed here. As a result of analysis of this part, Au 0.03 g/t, Ag <0.5 g/t and Cu 0.38% (Sample A02RF040) were obtained. The scale of zones with copper mineralization is as small as about 10 m in the long axis on the ground surface. (Fig. II-4-2-2-1-6 Survey results in the Prospecto Lass Burras)
In Incahuasi zone, trenches have been cut in two areas about 3 km apart, southwest (Incahuasi Sur) and northeast (Incahuasi Norte). Both of them were used for geochemical exploration of silicified/argillized alteration zones of monzonitic porphyry. From observation with the trenches used, weak silicified/argillized alteration is found but mineralization of sulfide mineral is slight. As a result of analysis of rock samples in trenches, values such as Au 0.10 g/t, Ag<0.5 g/t and Cu 0.01% (A02RF022) were derived. (Fig. II-4-2-2-1-7 Survey results in the Prospecto Incahuasi)
In addition to the above-mentioned areas, site verification was carried out for those, which were considered from ASTER image analysis to be probable alteration zones.
8) Comments • Mina Pancho Arias, Las Burras, Incahuasi (Norte, Sur) and main porphyry copper/molybdenum (gold) mineralized zones are located almost in the NNE-SSW direction because of restriction due to intrusion of monzonitic porphyry of Neogene Miocene. • Hydrothermal alteration zones are distributed in monzonitic porphyry, and Precambrian sedimentary rocks are located around the former in several places. Among alteration zones, those in the Mina Pancho Arias show zonal structure of potash alteration zones, phyllic - argillic alteration zones and propylite alteration zones. Porphyry mineralization is recognized in potash alteration zones and phyllic - argillic alteration zones. • These mineralized zones are small-scale, and it is judged that the ore grades of copper, molybdenum and gold are also low.

(2) El Pago area 1) Location and access
These mineral showings are located at lat. 27º05’ S, long. 65º55’ W, 3,000 m - 4,300 m above sea level. This place is administratively under Departamento de Monteros in Tucumán State. They are located in the mountains of Sierra del Aconquija on the upstream of Río de la Horqueta, and there is no road in the vicinity. Entering from Andalhuala by riding on a horse (two-day trip each way) or using a helicopter is the only way to reach there. (Fig. II-4-2-2-2-1 Location map of the El Pago area)
2) Mining concessions There is an old mine (Mina Rica) in this place of mineral showings. It is said that mining
area are established in the periphery. (Details unknown)
3) Past exploration and mining activities The outline of past investigations is as follows (mainly according to Carlos H. Morello, a
geological engineer). • Geological survey was carried out by the U.N. and Servicio Nacional de Geología y Mineria (SM) several times during the 1970s. (Several-hundred rock samples were collected, and geochemical analysis, analysis of altered mineral, etc. were carried out.) • Utah Co., Ltd., an American company, carried out investigation in 1987 (Eighteen rock geochemical samples were collected.) • Paramount Ventures & Finance Co., Ltd., carried out investigation in 1996. (Twenty-nine rock geochemical samples were collected.) • Pegasus Gold International Co., Ltd., carried out investigation in 1997. (Sixteen rock geochemical samples were collected.) • Rio Tinto Co., Ltd., may have carried out investigation thereafter. (Details unknown.)
4) Geology and geologic structure According to the geological map of Tucumán State on a scale of 1 to 500,000, the place of
mineral showings, El Pago, is within the area where Upper Precambrian bedrock (Piscoyacú gneiss) is distributed. Ordovician granite rocks are distributed in the northeast, and Portezuelo las Ánimas volcanic composite rocks of Tertiary Miocene (mainly andesitic volcanic rocks) are distributed in the north and northeast.
According to geological data obtained from SEGEMAR Tucumán branch office, there are three kinds of rock distributed in this place of mineral showings: Precambrian bedrocks (granulite, metasedimentary rock, gneiss etc.), dacitic - andesitic porphyry, and lamprophyre. (Fig. II-4-2-2-2-2 Geologic map of the El Pago area)
- 255 -
5) Mineralization and alteration In this place of mineral showings, an old mine called Mina Rica is known. It is said that this
mine was used for quartz prospecting by drift carried out in 1988 by the then mining-right holder. It is also said that quartz veins contained pyrite, and results of analysis such as Au grade 1.4 g/t, 6.8 g/t, and 12.6 g/t were obtained (according to Carlos H. Morello).
In this place of mineral showings, silicified - argillized alteration zones are distributed on the ground surface in the area of about 4 km x 2 km (generally extending from east to west). According to investigations carried out by SM and others, alterations here include potash alteration, sericitization, argillization, propylitization and silicification. In the investigation by the U.N. and SM in 1976, geochemical analysis was made for several-hundred rock samples. The results are as follows: Au~2.4 ppm (Highest value - same hereinafter: Sample 26426), Ag~8 ppm (Sample 67594), Cu~125 ppm (Sample 67501)*, Pb~400 ppm (Sample 25190), Zn~275 ppm (Samples 25151 and 26418) and Mo~80 ppm (Sample 25183). As known from these values, higher grades are found locally but,
generally, only low values have been obtained. (* This year, part of samples stored by SEGEMAR was analyzed again, as mentioned later; Cu 1,675 ppm was the highest value was obtained; Sample 23264.)
Last year, X-ray analysis was carried out for ten rock samples supplied by SEGEMAR Tucumán branch office (3 porphyry samples, 4 metamorphic bedrocks samples, 3 lamprophyre samples). From the result of X-ray analysis, the presence of the above-mentioned alteration has been confirmed. It was found that chalcopyrite and pyrite were contained in some samples.
6) Characteristics of the satellite image This place of mineral showings is located in the peripheral part of a vegetation zone, and is
an area where image analysis is difficult due to the influence of vegetation. In the ASTER false color (VNIR) image, the area of 4 km x 2 km presents a color tone which is remarkably different from the circumference and can be recognized as a large-scale alteration zone. When this part is seen in a 3D image, the situation like depressed topography (Bajo) surrounded by branch streams is recognized. According to the result of altered mineral identification with the Isograin Model used, sericite, chlorite, goethite, and a small quantity of epidote are distributed over the area of alteration zones. Outcrop of kaolin and jarosite is partly observed in alteration zone.
This place of mineral showings is located 30 to 40 km northwest of Agua Rica, Filo Colorado, and a prospecting area of porphyry copper deposits. In satellite image analysis, it is recognized that there is distribution of a group of alteration zones which extend in the NE-SW direction sporadically between Filo Colorado and El Pago and which mainly consist of sericite and goethite. Furthermore, although probable indication of alteration zones is recognized in the place 4 to 6 km northeast of El Pago, it is difficult to identify alteration zones with the satellite image used because this is a vegetation zone. (Fig. II-4-2-2-2-3 ASTER image analysis of hydrothermal alteration zones in the El Pago area)

7) Survey results X-ray analysis was made for 10 rock samples provided by SEGEMAR Tucumán branch
office, our counterpart in the last year. This year, site survey was carried out mainly for an old mine (Mina Rica) situated in the northern part of this zone and alteration zones in the northwestern part, and samples were collected. The number of collected samples is 17 in total. (The breakdown of analyses and tests is as follows: 15 geochemical analyses, one ore analysis, 13 X-ray analyses, 18 rock thin-section assessments and 4 ore polished thin-section assessments). In addition to geochemical analysis of 15 rock samples provided by SEGEMAR Tucumán branch office last year, data on analysis of rock geochemical samples and on alteration of rock samples, obtained by SM during the 1970s, was input in GIS and analyzed together with results of geochemical analysis and X-ray analysis in this investigation.
The old mine in Mina Rica was cut on the steep slope of the mountain (at about 3,770 m above sea level) and used for prospecting by drift of quartz stringers/networks in gneiss belonging to the Precambrian Piscoyacú complex The drift was excavated about 10 m along veins. Veins have strike and dip of N72°W, 78°S, and width of 50 to 70 cm. Sulfide mineral (mainly pyrite) is observed in quartz veins. As a result of analysis of vein samples, Au 0.01 g/t, Ag<1 g/t and Cu 0.01% were obtained (width of collection: 65 cm; Sample: A02RF104). In the results of analysis of ore samples, which had fallen near the pit mouth, Au 0.149 g/t, Ag 1.8 g/t (Sample A02KK048), Au 0.065 g/t, Ag 10.8 g/t (Sample A02TK048) etc. were obtained. As a result of microscopic observation of ore polished thin-sections, pyrite, goethite and small quantities of pyrrhotite and sphalerite were recognized in quartz veins (Samples A02RF104, A02RF105 and A02RF106). Wall rock around veins suffers strong silicification and argillization. In the results of X-ray analysis of alteration zones on upper bedrock of a vein, quartz, sericite, and trace quantity of chlorite and jarosite were detected (Samples A02RF105 and A02RF106). In the results of geochemical analysis of altered rock samples at the point about 300 m north of this old mine, values of Au 1.115 g/t, Ag<0.5 g/t and Cu 79 ppm were derived (Sample A02RF102). From the X-ray analysis test of altered rock (gneiss) around the said point, quartz sericite and small to trace quantities of chlorite, limonite and others were detected.
In this zone, alteration zones have been widely extracted in ASTER image analysis, as mentioned above. These alteration zones are distributed on the steep slopes of mountains, and, as far as we observed in the actual place, there were many parts that were difficult to access. Site investigation of the north end part of the western alteration zone is carried out. This alteration zone is mainly located in gneiss. The following results of geochemical analysis were obtained from a collected rock sample (Sample A02YH049): Au 0.191 g/t, Ag 11 g/t, Cu 104 ppm and Mo 1,005 ppm as the highest values. In the results of X-ray analysis of this part, quartz and sericite were the main compornents while small to trace quantities of chlorite and goethite were recognized, and alteration corresponded to phyllic-argillic alteration.
- 262 -
From the combination of results of X-ray analysis this year and the results of alteration analysis carried out by SM during the 1970s, the following state of output of alteration zones was recognized: (1) Alteration zone (phyllic - argillic type alteration and propylite type alteration) mainly consisting of quartz, sericite, chlorite and clay mineral on the ground surface in the area of 4 km x 2 km. Distribution of both types of alterations overlaps. (2)Around the center of these, potassic alteration zones are distributed where potassium feldspar (±biotite) is recognized(according to
materials of the 1970s). (3) In alteration zones in this zone, there are places where quartz stringers/networks are contained, and silicified zones are distributed around them. Quartz veins are considered to be mainly E - W oriented. Gold is partly contained in quartz veins. (Fig. II-4-2-2-2-4 Survey results in the El Pago area)
8) Comments • In The El Pago area, propylite alteration zones and phyllic - argillic alteration zones overlapping them are distributed in a wide area, and potassic alteration zones are distributed in the central part of hydrothermal alteration zones. Quartz stringers/networks exist partly in them, and it is considered that gold is contained there. • Around this zone, porphyry deposits such as Agua Rica and Filo Colorado are known. It is assumed that these were formed in relation to dacite/andesite intrusive rock of the Neogene. These deposits or mineralized zones run linearly in the NE -SW direction, and in the middle part of and on the extension line of them, alteration zones have been detected from ASTER image analysis, which is considered to indicate the existence of a tectonic line that controlled mineralization and alteration. • The El Pago area is located in the Sierra del Aconquija Mountains and has been scarcely investigated systematically so far due to limited accessibility. Therefore, this zone is still left as a virgin area, and according to the results of investigations and analysis of this year, it seems to have the possibility of being a predominant prospecting area of porphyry deposits depending on the procedure of future systematic investigation.

(3) Rachaite area 1) Location and access
The Rachaite area is located at lat. 22º52’ S, long. 66º08’ W, 3,600 m - 4,000 m above sea level. This place is located about 60 km directly west from Abra Pampa, and about 45 km south of Rinconada. Administratively, it is under Departamento de Rinconada in Jujuy State. The Rachaite area is reached by going from Abra Pampa on unpaved State Road 74 by a 4-wheel-drive car, and going south 4 km along Quebrada Liviala, on the east side of Rachaite village. The mileage is 58 km, and it takes about one- and -a-half hours to get there. (Fig. II-4-2-2-3-1 Location map of the Rachaite area)
2) Mining concessions The following mining areas are established in and around the place of the Rachaite area:
• Mining Area No. 546-S-1979 (Chocaya, Mining-right holder: Carlos Silva) • Mining Area Nos. 109 - O - 1997 and 110 - O - 1997 (Opawica Min. Ar. SA), 276 - W - 1997 and 277 - W - 1997 (Mario C. Rojo) • Prospecting Area Nos. 096 - O - 1997 (Opawica Min. Ar. SA), 113 - R - 1997 (RTZ Min. Exp. Ltd.) (Fig. II-4-2-2-3-2 Situation of concessions in the Rachaite area)
3) Past exploration and mining activities There is a record that lead and zinc were produced during the 1950s, but details are unknown.
4) Geology and geologic structure According to "Mina Pirquitas," a geological map on a scale of 1 to 250,000, the geology of
this zone consists of Coranzuli volcanic complex of the Tertiary Miocene. A place of mineral showings is located about 25 km northeast of Coranzuli caldera. Coranzuli volcano is a caldera of about 5 km in diameter, which is characterized by eruption of dacitic ignimbrite; it was formed by the eruption of ignimbrite, which occurred three times (5 Ma). On the other hand, Cerro Rachaite was formed in the early stage of a series of volcanic activities. The Rachaite place of mineral showings is located in the southern part of Cerro Rachaite and is made up of dacite lava formed in the early stage of volcanic activities (8 - 9 Ma). The whole southwestern part from the Rachaite place of mineral showings to Cerro Coranzuli is widely covered by ignimbrite. (Fig. II-4-2-2-3-3 Geologic map of the Rachaite area)
5) Mineralization and alteration In this region, alteration zones extending from south to north parallel to Quebrada Liviala
exist in two places, east and west. The eastern alteration zone has a length of about 3 km from south to north and the greatest width of 700 m from east to west. It forms a small, steep mountain with relative height of about 200 m, sandwiched by southern and northern streams. This zone is subjected to white argillized alternation and limonitic alteration. White argillized rock can be relatively clearly
- 267 -
distinguished from surrounding dacite and andesite. Andesite with no or weak alteration is dark black in color and has clear phenocryst (plagioclase, quartz and amphibole). White dacite is brecciated, and the matrix is filled up with limonite. By the naked eye, dark mineral does not remain, and argillized plagioclase phenocryst is observed. According to results of X-ray analysis, both dacite with plagioclase completely replaced by clay mineral (sericite, sericite/montmorillonite mixed-layer mineral, chlorite, kaolin, etc.) and dacite with part of plagioclase still remaining are recognized. Altered andesite is intruded by andesite veins presenting dark color to green. In dacite, N-S oriented fine fractures develop, which are filled up by limonite stringers. Near the mountaintop, a limonite layer considered to be recent is formed and iron is leached by acidic epithermal water sediments. There is an old mine (formerly a prospecting one) at the north end of the alteration zone in the east side. The direction of the gallery is N10°W, and it appears that lead/zinc stringers were prospected by drift. In waste, there is mixture of quartz veins containing galena/sphalerite. In the results of microscopy in the first year, disseminated - networked pyrite, coarse-grained sphalerite, small quantity of galena, arsenopyrite, and, as gangue, calcite and quartz were observed. In the results of ore analysis, the following values were obtained: Au 0.04 g/t, Ag 142 g/t, Pb 1.71%, Zn 2.5%(A01KN088), Au
0.025 g/t, Ag 2.5 g/t, Pb 0.18% and Zn 1.22% (A01YH050). On the other hand, the western alteration zone is exposed on the cliff part along small
streams. It has a length of about 1.3 km from south to north and a width of 400 to 500 m, and is subjected to strong white argillized alteration. In the results of analysis of this opaline quartz vein sample in the first year, both Au and Ag values were below the detection limit.
6) Characteristics of the satellite image Alteration zones detected in this place of mineral showings present white color and can be
identified very clearly in the false color image. In the color-ratio composite, strongly abnormal areas consistent with the white part in the false color image were detected. In the results of altered mineral identification with the Iso-grain Model used, the color tone indicating alunite - kaolin acid alteration zones and sericite alteration zones were detected in the same places. The color tone representing goethite and quartz is observed there. (Fig. II-4-2-2-3-4 ASTER image analysis of hydrothermal alteration zones in the Rachaite area)
7) Survey results The phase I survey was carried out mainly regarding the north part of alteration zones
(Number of collected samples: 25). This year, site investigation was conducted mainly regarding the south part of east and west alteration zones. The number of collected samples is 30 in total: (10 geochemical analyses, 26 X-ray analyses and 3 rock thin-section identifications).
In the east alteration zone, which is of the largest scale, old mines were cut in several places in the north part, as described in last year’s report, and were used for prospecting by drift of quartz - calcite stringer zones with an almost N - S strike, which contain sulfide mineral. Veins have dacite as
- 273 -
host rock and contain mainly pyrite, galena and sphalerite. Silver is contained in sulfide mineral, although quantity is small. The edge of veins is subjected to weak silicification and alteration with sericite as the main. In this year’s survey, many places receiving strong silicification - pyritic alteration were found in clay alteration zones of dacite along streams and on ridges. In these places, strong alteration zones made up of quartz, pyrite, gypsum and clay mineral are distributed in the form of an irregular vein with a width of several meters. Parts where quartz veins containing pyrite exist were recognized, although only partly. In the results of analysis of these alteration samples or quartz veins, the values of Au, Ag, Pb and Zn were low; the highest Au value was 0.02 g/t (Sample A02RF062) and the highest Ag value was 0.8 g/t (Sample A02RF067). Namely, though alteration zones in this zone are disseminated by sulfide mineral with pyrite as the main, mineralization of Au, Ag or base metal is weak. According to the results of X-ray analysis of samples collected in this zone, altered mineral has mineral combination of quartz - opaline quartz, sericite, and sericite/montmorillonite mixed-layer mineral, and is accompanied by small to trace quantities of kaolin, jarosite, chlorite, calcite, alunite, pyrophyllite, gypsum and pyrite.
The alteration zone in the west part is basically similar to the alteration zone in the east part, mainly a mineral combination of quartz-opalic quartz, sericite, and sericite/montmorillonite mixed-layer mineral. It is accompanied by small to trace quantities of kaolin, jarosite, chlorite, alunite, pyrophyllite, gypsum and pyrite. (Fig. II-4-2-2-3-5 Survey results in the Rachaite area)
8) Comments • Ag-Pb-Zn mineralization in the Rachaite area is reserved in Miocene dacite lava, and is considered to be related to a hydrothermal system formed in the relatively early stage of dacitic Coranzuli caldera complex activities, which occurred in the middle to later Miocene. • In the survey carried out successively from last year’s investigation, silicified zones and mineralization/alteration zones where quartz veins were accompanied by mineralization of sulfide mineral with pyrite as the main were newly found in several places in the southern part of the zone. However, no noteworthy grades were derived from the results of analysis of collected samples. • Considering the results of both last year’s and this year’s investigations in a comprehensive manner, although strongly acid alteration zones are distributed in this zone, as main sulfide mineral is pyrite, it is judged that mineralization of Ag, Pb and Zn is limited to a very small part of veins only.
- 275 -
(4) Cerro Galán area 1) Location and access
This alteration zone is located at lat. 25º52’ S, long. 67º02’ W, about 5,000 m above sea level. This place is administratively under Departamento de San Carlos in Salta State and is located about 40 km directly northeast from Antofagasta de la Sierra, and about 18 km north of Laguna Diamante. The distance is 80 km from El Penón along State Road 43 by driving a 4-wheel-drive car, but depending on the season, travel by car can be difficult. (Fig. II-4-2-2-4-1 Location map of the Cerro Galán area)
2) Mining concessions Around the Cerro Galán caldera outer-wall, companies such as BHP and RTZ established
mining areas during the 1980s and the 1990s. These mining areas are now under the jurisdiction of the state. In the central part of the caldera, Reserva D-216-1996 is established, and no mining area can be made. (Fig. II-4-2-2-4-2 Situation of concessions in the Cerro Galán area)
3) Past exploration and mining activities In this zone, volcanololgic studies mainly covering ignimbrite were conducted by American
and English geologists during the 1980s. Although geological survey and geochemical exploration were carried out by BHP at the end of the 1980s, it is recognized that the results were negative (information of SEGEMAR Tucumán branch office). After that, although it seems that several prospecting companies conducted small-scale investigations, no official records are kept.
4) Geology and geologic structure Mineral showings is located on the northwestern wall of the Cerro Galán caldera. This
caldera is a volcanic caldera complex of about 40 km from south to north and about 25 km from east to west, and develops on Precambrian to Paleozoic basements, which has changed to horst/graven. This horst/graven is controlled by faults, running in the direction of south to north, which are about 20 km distant from each other.
According to "Cachi," a geological map on a scale of 1 to 250,000, and other existing geological materials, the geology around these alteration zones consists of upper Proterozoic schist, phyllite, hybrid rocks (called Pachamama layer and Río Blanco metamorphic rocks), granite - diorite rocks (Silurian, called Ore composite rocks), sandstone/conglomerate rocks (Lower Silurian to Devonian system, referred to as Falda Ciénaga layer), monzonite granodiorite (Devonian?), and dacitic to andesitic lava rocks and ignimbrite of the Neogene Miocene to Pleistocene, which cover them. Basements border Neogene volcanic rocks on a fault with inclination to the east, "Falla del Medio." For Neogene volcanic rocks, age determination and classification are made as follows: dacitic porphyry (Inca Viejo layer, 15 Ma), dacitic - andesitic stratovolcano (Beltrán layer or Tebenquicho layer, 14.5 Ma), Toconquis stratovolcano, Colorado stratovolcano, Pabellon stratovolcano (age of all
- 279 -
of which is 7 to 4 Ma), old ignimbrite (such as Real Grande ignimbrite, 6 to 4.2 Ma), and new ignimbrite (Cerro Galán ignimbrite, 2.2 Ma).
Alteration zones in this zone are located on the wall part of the Cerro Galán caldera, as mentioned above. In the central part of the alteration zones, crossing of E-W oriented and NE-SW oriented lineaments is recognized (Is it a fault?). (Fig. II-4-2-2-4-3 Geologic map of the Cerro Galán area)
5) Mineralization and alteration This alteration zone was found as a result of analysis of alteration zones by the use of
ASTER data, but details are unknown because past investigation materials have not been obtained. As mentioned in the section on tectonic structure, however, it is considered, from the fact that a caldera fault and a lineament estimated to be a radial fault crossing it are distributed, that there is the possibility of a hydrothermal alteration zone formed by rise, along the part crossing the fault, of epithermal water accompanying volcanic activity when the caldera structure was formed. Therefore, it was expected that this alteration zone has reserve of epithermal deposits formed by such hydrothermal activity.
6) Characteristics of the satellite image Several alteration zones have been detected from the Cerro Galán caldera by LANDSAT TM
and ASTER image analyses. Most of these alteration zones run along the caldera wall. The largest of them is in the northwest part of the caldera. This alteration zone is about 4 km in diameter and presents the color tone mainly representing the presence of kaolin in the results of altered mineral identification. (Other than this, alteration representing small amounts of alunite, sericite and goethite is recognized.) About 500 m south of this large-scale alteration, a small-scale alteration zone group that shows the color tone representing distribution of alunite and kaolin has been detected. In the western part of Laguna Diamante, indications of alunite, kaolin and sericite are recognized. (Fig. II-4-2-2-4-4 ASTER image analysis of hydrothermal alteration zones in the Cerro Galán area)
7) Survey results The number of samples collected in the field survey is 37 in total (21 geochemical analyses,
33 X-ray analyses and 4 rock thin-section identifications). In the result of geochemical analysis of altered rock, almost all of samples had Au<0.005
ppm, Ag<0.5 ppm and Cu 2 - 18 ppm. In the X-ray analysis test of altered rock, altered mineral made up of a combination of
sericite, chlorite and calcite was recognized in many samples. A large quantity of kaolin was recognized in some samples (Samples A02KK041, A02KK045). Only in a very limited number of samples, trace quantities of jarosite (A02KK036, A02KK040) and pyrite (A02YH036) were detected. (Fig. II-4-2-2-4-5 Survey results in the Cerro Galán area)
- 282 -
8) Comments • In this area, several lineaments were recognized on the ASTER images. They were interpreted as faults. Some of them show a characteristic feature of normal faults formed by caldron subsidence, and others exhibit a nature of radial faults, which crosscut the former. On the basis of such evidence, the alteration zones in this area are assumed to be formed by the hydrothermal solution, which ascended along the intersections of faults during the volcanic activity. • The hydrothermal alteration zones, which were detected by the ASTER image analysis, were surveyed in the field. The geochemical analysis on the samples obtained during the survey this phase, however, showed no significant value. • Such results present no positive indication for the economical point of view, at least on the surface. We cannot see the potential of the depth because there is no information at the moment. In addition to it, there is another difficult condition for the survey of this area; the altitude is very high, more than 5,000 m. The necessity for the further work on this area is thought to be very little.

4-3 Discussion of survey results
4-3-1 SEDEX/VMS deposits
(1) General geochemical analysis
1) Introduction
By using the results of the geo-chemical analysis of 197 samples in total collected from
four areas of Aguilar range area, Pumahuasi area, Santa Victoria Mountains area, and La Colorada
area that are selected to explore SEDEX/VMS deposits, a principal component analysis that is one of
the unsupervised classification methods among multivariate analyses was carried out.
Principal component analysis attempts to explain variations included in one set of
multivariate data by a set of a smaller number of variations (principal components) that are not
correlated to each other. New variables (principal components) are called 1st principal component,
2nd principal component, ・・・・・ and Nth principal component. It is said that the majority of the
variations of the data can be explained by the first several principal components. Here, this principal
component analysis was carried out for the purpose of discriminating expected mineralization such
as SEDEX or VMS, etc. as principal components from the variations of the analytical values of 29
elements out of 197 samples in total. The analysis was also carried out for the purpose of
discriminating potential zones of this mineralization from the geographic distribution of the principal
component score.
2) Used data
The data used are chemical analytical data (Table II-4-3-1-1) of rock (and, ore) samples
collected from four areas of Aguilar range area, Pumahuasi area, Santa Victoria Mountains area, and
La Colorada area. The total number of the samples is 197, and the breakdown is shown as follows.
Aguilar Range area: 46
Pumahuasi area: 7
Santa Victoria Mountains area: 104

The 29 elements analyzed are Au, Ag, Al, As, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, K, Mg,
Mn, Mo, Na, Ni, P, Pb, S, Sb, Sr, Ti, V, W, Zn, and Hg.
3) Pre-processing of data
Prior to the processing of statistical analysis, the 1/2 times value of the detection limit
value was conveniently adopted for the value below the minor detection limit. The two times value
of the detection limit value was adopted for the values higher than the upper detection limit. In

addition, as a result of normality test by histogram, the analysis values were logarithmically
conversed for 22 elements (Au, Ag, As, Ba, Be, Bi, Ca, Cd, Co, Cu, Fe, Mn, Mo, Ni, P, Pb, S, Sb, Sr,
W, Zn, and, Hg) that showed the tendency of logarithmic normal distribution (positive asymmetric
distribution).
4) Calculation processing
Following WWW data analysis “Black Box", one of the web software for principal
component analysis, was employed for the calculation.
http://aoki2.si.gunma-u.ac.jp/BlackBox/BlackBox.html (in Japanese)
According to the arrangement for using this “Black Box", all data was converted into text
files (ASCII files). The principal component analysis starts with the calculation of a correlation
coefficient matrix. The statistic output obtained by WWW data analysis and the correlation
coefficient matrix are shown in Table II-4-3-1-2 and 3, respectively. In this table, correlation
coefficients 0.5 or larger that are assumed high in correlation are shown in a bold-faced type. For
instance, it is seen that the elements showing high correlation with the main, metallic element Zn of
SEDEX deposits are Cd, Ag, Pb, Sb, Hg, Cu, S and Au.
5) Calculation result
The matrix of the principal component loadings obtained is shown in Table II-4-3-1-4. The
relation of each principal component to the elements is shown in Fig.II-4-3-1-1. The principal
component scores of the 197 samples calculated based on the principal component loadings are
shown in Table II-4-3-1-5 together with the geological description etc. In Table II-4-3-1-4 (afore
mentioned), figures whose absolute values of loadings are 0.5 or larger are shown in a bold-faced
type. (The plus and minus signs are relative to each other, and there is no problem in the
interpretation even if all signs are reversed per principal components.) The cumulative contribution
rates of the six principal components extracted are 74%. Since the contribution rates of the first three
principal components (PC1, PC2 and PC3) accounts for more than 50%, a geochemical feature of
197 samples in these four areas can be almost explained by these three principal components. The
features of the three main principal components presumed from these diagrams are shown as follows.
1st principal component (PC1)
Al, Ti, V, Be, Mg, K, Ni, Fe, Co, and Ba show highly negative correlation (principal
component loadings below-0.5) with the 1st principal component. They are presumed to be principal
components that represent a composition of a certain kind of rock. Because pelitic rocks (shale and

- 297 -
slate, etc.) generally show a negative high score, and sandstones (sandstone and quartzite, etc.) a
positive high score, these are presumed to be a principal component, which is related to the amount
of the muddy material. The 1st principal component is similar to the 1st principal component for the
35 drill core samples from La Colorada area, and the 2nd principal component for the 72 drill core
samples from the Aguilar range area.
2nd principal component (PC2)
Ag, Sb, Hg, Zn, Cd, Pb, S, and Au show highly negative correlation (principal component
loadings below-0.5) with the 2nd principal component. Because these elements are common in the
Esperanza ore body being thought to be a typical model of SEDEX deposits, the 2nd principal
component is presumed to be the principal components showing the SEDEX mineralization. The 2nd
principal component is discriminated as the 1st principal component for the 72 drill core samples
from the Aguilar range area, and the 3rd principal component for the 35 drill core samples from La
Colorada area.
3rd principal component (PC3)
Bi, Au, W, Fe, and Ba show highly positive correlation (principal component loadings :0.5
or larger) with the 3rd principal component. For the 35 drill core samples of La Colorada area, these
elements plus Co and Cu are extracted as the 2nd principal component with high correlation.
Because these are common in La Colorada ore bodies consisting mainly of pyrrotite, accompanied
by chalcopyrite, marmatite, arsenopyrite, galena and ilmenite, and also a small amount of
bismuthinite, natural bismuth, and electrum, they are presumed to be the principal components
showing the mineralization (VMS?) represented by La Colorada deposits.
6) Score distribution of principal components
Classification of each principal component scores is made based on frequency distribution
(Fig.II-4-3-1-2) of each principal component score.
1st principal component (PC1)
Scores of the 1st principal component are distributed within the range of -4.895 to +7.012.
These are presumed to be principal components that relate to a kind of composition (perhaps grain
size) of the rock, and have significant meanings both on the positive side and negative side. So, the
symmetrical classification centering on the zero value was adopted.
Score distributions in the Aguilar Range, Pumahuasi, Santa Victoria Mountains and La
Colorada areas are shown in Fig.II-4-3-1-3 (1) - (4). The blue circles and yellow circles nearly
correspond to shale and sandstone (including phyllite) of the sample descriptions, respectively.

2nd principal component (PC2)
Scores of the 2nd principal component, ranging from -19.688 to +2.295, show a
distribution extremely biased to the minus side. Because the loadings of the elements highly
correlated with the 2nd principal component shows minus (Table II-4-3-1-4 referred to earlier), it
indicates that the higher scoring is on the minus side, the stronger the elements of these principal
components are. Because the 2nd principal component predict the possibility of being SEDEX
deposits, the higher the scoring on the minus side, means the stronger the possibility of SEDEX
deposits. In Fig.II-4-3-1-4 (1) - (4), the values of -1.000 or less of 18 samples corresponding to about
9% of the whole are displayed in red circles, furthermore, the values of -5.000 or less of six samples
corresponding to about 3% of the whole displayed in a large red circle. 13 samples out of 18 samples
with values of -1.000 or less and six samples with values of-5.000 or less as well are collected from
ore bodies and their surroundings of Esperanza, Aguilar, Oriental and Pirita (Rincon) in the Aguilar
Ranges area. Two samples of the other five samples with values of -1.000 or less are all shale in the
vicinity of Chaussette ore deposits of the Pumahuasi area and in the vicinity of Pumahuasi ore
deposits. The other three samples are all shale samples collected respectively in the upstream of
Vicunayo valley of North route, in the west of Santa Victoria town and in La Cienaga ore deposits of
South route in Santa Victoria Mountains area. No high score sample has been recognized in La
Colorada area.
In Aguilar Range area, the existence of the SEDEX mineralization was geochemically
presented because of a high score distribution of the 2nd principal component not only in Esperanza
deposits, which is assumed to be a typical model of SEDEX deposits, but also in Aguilar deposits,
Oriental and Pirita mineral showings. However, in Rio Grande mineral showings thought to be
similar SEDEX mineralization located about 3km northeast of Esperanza deposits, high score of the
2nd principal component has not been obtained against our forecast.
It has been thought that the Pumahuasi area is covered by the sediments of Acoite
Formation which is the upper part of the Santa Victoria Group, and the existence of SEDEX
mineralization hosted in the lower part has been regarded as negative. However, Because of a high
score of the 2nd principal component obtained, further examination is required on the shale in the
vicinity of Chaussette deposits and Pumahuasi deposits of this area.
In Santa Victoria Mountains area, a lot of samples (104 samples) were examined;
nevertheless, only three samples show high scores of the 2nd principal component. Furthermore, the
score values are not remarkably high, ranging from +1.2 to +1.4, even though they are classified in
high score group. Among these samples, however, two samples from upstream of Vicunayo valley
and from the west of Santa Victoria town indicated the possibility of the existence of the SEDEX
mineralization, according to the discriminant analysis that both exist in the vicinity of the ore zone of
- 304 -
the hanging and foot walls boundary. Other high score sample of A02CX070 is collected in La
Cienaga mineral showings, and, it is suggested that they are ore zone itself in the foot walls of ore
zone according to the discriminant analysis.
In La Colorada area, high score of the 2nd principal component is not recognized according
to the result of the principal component analysis of these 197 samples. However, as the result of the
principal component analysis, intended only for 35 core samples of the La Colorada area, the
possibility of the existence of SEDEX mineralization in this area still exists, because principal
components showing SEDEX mineralization corresponding to the 2nd principal components is
discriminated as the 3rd principal component.
3rd principal component (PC3)
Scores of the 3rd principal component are distributed within the range from -3.332 to
+12.424. Because the loadings of the elements highly correlated with the 3rd principal component
indicate plus (Table II-4-3-1-4, referred to earlier), it is shown that the elements of the principal
component are stronger as score becomes higher. The possibility of the principal component that
shows mineralization represented by La Colorada deposits can be forecast from the 3rd principal
component, it is indicated that the possibility of this mineralization becomes stronger as the score
becomes higher. In Fig.II-4-3-1-5 (1) - (4), 27 samples with scores of +1.000 or larger that account
for about 14% of the whole are displayed in red circle, 11 samples with scores of +2.000 or larger
that account for about 6% of the whole in medium red circles, furthermore, five samples with scores
of +5.000 or larger that account for about 2.5% of the whole in a large red circle.
Out of 27 samples with the scores of +1.000 or larger, 13 samples are collected in La
Colorada area, nine samples in the Aguilar Range area, three samples in the Santa Victoria
Mountains area, and two samples in the Pumahuasi area. Further, out of 11 samples with the scores
of +2.000 or larger, six samples are collected from ore bodies of Rio Grande, Pirita (Rincon),
Oriental, and Aguilar and the surrounding of their ore bodies excluding Esperanza deposit in the
Aguilar Range area, and five samples are collected around the surrounding of La Colorada deposits
in La Colorada area, in its northern part, and in Limeca in its southern part. Out of five samples with
the scores of +5.000 or larger, four samples are collected in Rio Grande, Pirita (Rincon), and
Oriental excluding Esperanza deposits in the Aguilar Range area and one sample is collected from
chlorite alteration zones around La Colorada deposits in La Colorada area.
In Aguilar deposits and its peripheral mineral showings, mineralization of La Colorada
deposits type overlaps on SEDEX mineralization area. As the result of the principal component
analysis on 197 samples, however, the above-mentioned phenomenon cannot be recognized with
regard to Esperanza deposits. Rio Grande mineral showings so far thought to be SEDEX
mineralization located in the northeast of Esperanza deposits, and Despensa mineral showings
- 309 -
located in about 4km in the southeast direction of Tapada and resembled Despensa mineral showings
to Rio Grande though it is very small-scale. A high score of the 3rd principal component exists while
a high score of 2nd principal component, which shows SEDEX mineralization is not recognized.
In the Pumahuasi area, in the alternation of fine-grain sandstone and shale beds in the
northern part of Chaussette deposits and in the alternation of micaceous shale and fine-grain
sandstone beds in the northwest foot of Cerro Morado on the area south edge (small-scale alteration
zone by ASTER image), a high score of the 3rd principal component has been obtained. It is forecast
that the former has some relation to Chaussette deposits of Pb-Zn vein deposits type located in the
south, while the latter, a relation with the small-scale alteration zone discriminated by ASTER image
is expected.
In Santa Victoria Mountains area, in the same manner as the case of the 2nd principal
component, the number of the samples with the high score of the 3rd principal component is only
three; moreover, the scores only range from +1.10 to +1.65, not being remarkably high in score even
though they are supposed to be of a high score.
In La Colorada area, out of 40 samples provided for the study, 13 samples show high score
(+1.000 or larger). Nine samples are distributed to the south up to Limeca along the NE-SW
extension trend of Cobres Eruptive Oire (Middle Ordovician) distributed to the north around La
Colorada deposits and the four samples are distributed along the valley in the south of Chuschuyo
mountain.
7) Conclusion
In four areas of Aguilar Ranges area, Pumahuasi area, Santa Victoria Mountain area and La
Colorada area selected to explore SEDEX/VMS deposits, principal component analysis, one of the
unsupervised classification methods was carried out by using the collected analytical data of 197
samples. As a result, it was clarified that the wide viewed geochemical variation in this region can be
explained by three principal components (One primary principal components which relate to
composition of rock and the secondary and ternary principal components that relate to
mineralization). One of the principal components that relate to mineralization is the secondary
principal components, which shows highly negative correlation with Ag, Sb, Hg, Zn, Cd, Pb, S, and
Au (principal components loading of below -0.5), is presumed to be principal components that show
SEDEX mineralization. Another principal components, which relate to mineralization, are the
ternary principal components, showing highly positive correlation with Bi, Au, W, Fe, and Ba,
(principal component loading: 0.5 or larger). These are presumed to be principal components, which
show mineralization represented by La Colorada deposits. The following is clarified from the score
distribution of the secondary and the ternary principal components that relate to ore deposits.
- 314 -
In Aguilar Range area, it was clarified that SEDEX mineralization related, not only with
Esperanza deposits which is assumed to be a typical model of SEDEX deposits, but also with
Aguilar deposits, Oriental mineral showings, and Pirita mineral showings.
In Aguilar deposits and mineral showings around its periphery except Esperanza deposits,
it turned out that the existence of mineralization represented by La Colorada deposits overlapped
with that of SEDEX mineralization.
On the other hand, with regard to Rio Grande mineral showings that existed in the
neighborhood of the northeast of Esperanza deposits and were thought to show similar SEDEX
mineralization, in contradiction to the forecast, it turned out that mineralization represented by La
Colorada deposits was related rather than SEDEX mineralization.
No one can say otherwise that Santa Victoria Mountain area is a region where
mineralization is scarce so long as judging it only from the designated ground chemical data of 104
samples. However, because a geochemical symptom of SEDEX mineralization is observed, though it
is weak, the possibility of the SEDEX mineralization existence is not denied.
In La Colorada area, naturally, mineralization represented by La Colorada deposits
remarkably develops. This mineralization is distributed indistinctly harmonizing with (NE-SW) the
extension of LaCobres Complejo Eruptive Oire (Middle Ordovician). In the La Colorada area
including Limeca in question, the result suggesting the association of SEDEX mineralization has not
been obtained. However, from the result of a partial principal component analysis, intended for only
35 samples of the cores of the La Colorada area, the possibility of the SEDEX mineralization in this
region including Limeca still exists, because principal components suggesting this SEDEX
mineralization have been discriminated
(2) SEDEX/VMS deposits
Targeting the exploration of SEDEX/VMS deposits in 4 areas, field surveys and sample
collections were made and various laboratory examinations including fossil identification and
chemical analysis were carried out in order to clarify petrological, paleontological and geochemical
features of the SEDEX/VMS ore horizon and their hanging and foot walls and to discover horizon
similar to those of known SEDEX ore deposits. To understand paleontological stratigraphy, which is
the essential factor for SEDEX deposits, five samples in total for Conodont identification and 19
samples in total for the pollen identification were collected. Only among the limestone of the Santa
Rosita Formation of the lower part of the Santa Victoria Group in the vicinity of Santa Victoria town,
Rossodus tenuis (Miller, 1980), and Drepanoistodus sp. were identified, mixed with gastropod and
brachiopod, and it was clarified that this was Tremadocian Deposits (absolute age of almost 487-
489m.y) of the lower part of the regional Ordovician.
- 315 -
The principal component analysis was made by using the analytical data of 197 rock
samples in total collected from the four areas. In addition, the discriminant analysis and the principal
component analysis were made by using the obtained analytical data of drilling cores in Aguilar
Range area and the La Colorada area, where respectively Esperanza ore bodies of SEDEX-type and
La Colorada ore bodies assumed to be VMS-type were intersected by drillings. As a result of the
principal component analysis, the following facts relating to mineralization were clarified.
In Aguilar Range area, SEDEX mineralization highly correlated with Ag, Sb, Hg, Zn, Cd,
Pb, S and Au contributes not only to Esperanza deposits, which is assumed to be typical model of
SEDEX deposits, but also to Aguilar deposits, Oriental and Pirita mineral showings. In Aguilar
deposits and its peripheral mineral showings except for Esperanza deposits, mineralization
represented by the La Colorada deposit and highly correlated with Bi, Au, W, Fe and Ba exists while
overlapping with SEDEX mineralization. To the Rio Grande mineral showings located in about 3km
northeast of Esperanza deposits, mineralization represented by La Colorada deposits contributes
rather than to the SEDEX mineralization.
In Santa Victoria Mountains area, since a geochemical indication of SEDEX mineralization
is recognized, though not remarkable, the possibility of the existence of the SEDEX mineralization is
not to be denied.
In the La Colorada area, the mineralization represented by La Colorada deposits
remarkably develops naturally. This mineralization is distributed indistinctly harmonizing with in the
NE-SW extension trend of the La Cobres Faja Eruptive del Puna (Middle Ordovician). As a result of
local principal component analysis for only drilling cores of La Colorada deposits, the principal
component, which suggests SEDEX mineralization, is extracted. For this reason, the possibility of
the existence of SEDEX mineralization in this area including Limeca area still exists.

4-3-2 Porphyry copper and epithermal type deposits (1) Hydrothermal alteration [Porphyry copper deposits]
Before examination of hydrothermal alteration accompanying porphyry deposits in NOA region, let's consider Bajo de la Alumbrera deposits and Agua Rica deposits in Catamarca State, representatives whose data has been made public so far.
Baja de la Alumbrera deposits are porphyry copper/gold deposits whose host rock are Farallón Negro volcanic complex of the Miocene and dacitic porphyry (about 7 Ma), which intrudes into them. A primary alteration zone in Bajo de la Alumbrera is composed of the following four facies running from the center towards the fringe as a concentric circle: (1) Quartz-magnetite ±k feldspar alteration, (2) Potassic alteration, (3) Chlorite - epidote (propylitic) alteration and (4) Feldspar destructive alteration. Mineralization of gold/copper mainly appears in (2) potassic alteration zones. (Pyrite is also seen in (3) propylitic zones, which is accompanied by small quantity of molybdenite, sphalerite and galena.) (Ulrich and Heinrich, 2001)
Agua Rica deposits are porphyry copper/gold deposits whose main host rock is feldspathic porphyry and breccia veins (8 - 5 Ma) intruding into basements and granite rocks of the Precambrian to Paleozoic, and are accompanied by small quantity of molibdenum. Hydrothermal alteration zones in Agua Rica deposits are a little more complicated than those in Bajo de la Alumbrera deposits. It is known from the period of generation that there are the following three facies: (1) Potassic alteration (accompanied by weak Cu - Mo mineralization), (2) Potassic alteration in the central part and prophylitic alteration around it (accompanying the main stage of Cu - Au - Mo mineralization with primary chalcopyrite as the main body) and (3) Phyllic - advanced argillic alteration (which is epithermal alteration, overprints (1) and (2), and accompanies mineralization of Cu - Au - Ag - As - Pb - Zn with covellite as the main). (Landtwing, et al., 2002)
In the Pancho Arias area where field survey was carried out this year, several hydrothermal alteration zones are observed. Among them, there is output of potassium alteration zones with quartz - biotite - potassium feldspar as the main body within the area of 1 km x several-hundred meters centering on monzonitic porphyry. In this zone, there is also outcrop of phyllic - argillic alteration zones characterized by mineral combination of quartz, sericite and kaolin and containing small to trace quantities of geothite and jarosite. As for the phyllic - argillic alteration zones, there is distribution of two long and narrow zones extending in parallel in the NE - SW direction around the old mine, and of small-scale zones in several places northwest of them. Propylite alteration zones made up of chlorite and epidote are distributed surrounding these alteration zones. Mainly molybdenite and small quantities of chalcopyrite and pyrite are mineralized in part of the potassium alteration zones, and mainly pyrite is mineralized in the phyllic - argillic alteration zones. Mineralization of these sulfide minerals forms dissemination and stringers. In addition, mainly silicification, sericitization, and partly chloritization, all of which accompany dissemination of sulfide mineral, are found in Las Burras and Incahuasi in the south part.
- 317 -
In The El Pago area, alteration zones (phyllic - argillic alteration zones and propylite alteration zones) mainly made up of quartz, sericite, chlorite and clay mineral are distributed on the ground surface in the area of 4 km x 2 km extending from east to west. Around the center of them, potassium alteration zones where potassium feldspar (±biotite) is recognized are output. Distribution of quartz, sericite, chlorite and clay mineral spreads over the alteration zones, and ranges of propylite zones and phyllic-argillic alteration zones overlap each other. There are places where quartz stringers/networks exist in these alteration zones, and silicified zones are distributed around them. Gold is contained in some quartz veins.
In the case of El Alisar ore deposits, which were investigated last year (porphyry copper/gold deposits located about 40 km northeast of the El Pago area), alteration zones are distributed asymmetrically in a semi-circle/concentric-circle form. From its center to the outside, there is distribution of potassium alteration zones (characterized by biotite, quartz and potassium feldspar (microcline)), sericite - clay alteration zones and propylite alteration zones (Phase I’s report).
Characteristics of hydrothermal alteration zones accompanying porphyry mineralization in this zone are summarized from the above, as follows: alteration zones can be roughly divided into potassium alteration zones in the central part and propylite alteration zones in the periphery; porphpyric copper/gold ore deposits accompany potassium alteration zones, mainly. There is output of phyllic - argillic alteration zones made up of quartz, sericite and clay mineral, and two cases are recognized: where a phyllic - argillic alteration zone forms zonal structure with propylite zone or overlaps a propylite zone (El Pago, El Alisar), and where the state of output in such a form to cut a propylite zone is shown (Pancho Arias). In Agua Rica ore deposits, phyllic - highly argillic alteration is deemed to be of the epithermal period after the period of potassium alteration/propylite alteration, and the possibility that the stage of alteration is also different in the case of the Pancho Arias area can be considered.
[Epithermal gold deposits] Hydrothermal alteration in the Rachaite and Cerro Galán areas, field survey of both of which
was carried out this year, is accompanied by acid alteration of the high sulfur type. In the Rachaite area, there is distribution of two white alteration zones extending from south
to north in Miocene dacite lava. Both the eastern alteration zone (3 km x 0.7 km) and the western alteration zone (1.3 km x 0.4 - 0.5 km) are subjected to strong white argillization (composed of quartz/opal, sericite, sericite/montmorillionite mixed-layer mineral, chlorite, kaolin, alunite, jarosite, etc.) and limonitic alteration. In some alteration zones, quartz veins containing pyrite and Ag, Pb, Zn etc. exist, and the vein fringe is accompanied by a silicified/ seriticized alteration zone.
In the Cerro Galán area, several alteration zones have been detected from dacite in Galán caldera of the Miocene to Pleistocene. Almost all of these alteration zones are aligned along the caldera wall. The largest one of them is located in the northwest wall part of the caldera. This alteration zone is about 4 km in diameter and is an acid alteration zone mainly composed of kaolin.
- 318 -
Besides it, small quantities of jarosite, sericite, chlorite and pyrite are recognized. About 500 m south of this place, there is output of a small-scale alteration zone group made up of alunite and kaolin. Indication of alteration of alunite, kaolin, sericite, etc. is recognized in the western part of Laguna Diamante.
Characteristics of hydrothermal alteration zones accompanying epithermal mineralization in this zone are summarized as follows: Alteration zones have properties of acid alteration with kaolin, sericite, montmorilonite, alunite, quartz, chlorite and jarosite as the main, and accompany dacitic caldera volcanic activities of the Miocene. Activities of hot water are controlled by tectonic movement in formation of a caldera, and are generated on the caldera wall or along faults, which occurred there. The main body of mineralization is pyrite, and, in the Rachaite area, mineralization of Pb/Zn, which is accompanied by Ag partly in veins, is recognized but is of very small scale. No noteworthy mineralization was recognized in the Cerro Galán area.
(2) Comparison of the results of the alteration analysis using the ASTER images with the results of the survey [Porphyry copper deposits]
In the Pancho Arias area, main alteration zones in three places were detected from alteration analysis with ASTER images used. As a result of alteration mineral identification by the use of the Iso-grain Model, those near the old mine in the Mina Pancho Arias show zonal structure of alteration zones (two zones were identified) presenting characteristics of sericite - kaolin - geothite (- jarosite) and alteration zones made up of chlorite and epidote around them. In the northwestern side of the old mine, several small-scale alteration zones mainly composed of sericite and kaolin were found inside and around alteration zones made up mainly of chlorite and epidote. Alteration zones were also detected in several places south of the Mina Pancho Arias. In Las Burras, although a large group of alteration zones is not recognized, in Incahuasi (south of Las Burras) and around it, alteration zones with long axis of 1 - 3 km which are composed of sericite and chlorite were grasped in several places.
Alteration zones detected near the Mina Pancho Arias almost agree with the following distribution areas of hydrothermal alteration zones presenting zonal structure mentioned in the previous section. (They consist of Potassic alteration zones (biotite - potassium feldspar) in the central part, phyllic - argillic alteration zones (quartz - sericite - clay mineral) surrounding them, and propylite alteration zones (accompanied by chlorite - epidote - calcite and pyrite) in the outside periphery.) Areas where sericite, kaolin and goethite (and jarosite) were detected in the satellite image correspond to phyllic - argillic alteration zones, and parts mainly made up of chlorite and epidote around them corresponds to propylite alteration zones. Though image analysis data has not been examined closely yet, calcite in addition to chlorite and epidote has been detected in the area corresponding to propylite zones. Detection of potassium alteration zones in the central part by means of satellite image analysis could not be tested because calculation of corresponding constituents has not been performed.

A sericite - kaolin alteration zone in an alteration zone made up of chlorite and epidote, which was detected in satellite image analysis of the northwest part of the old mine in the Mina Pancho Arias this year, corresponds to a phyllic - argillic alteration zone in a propylite zone, and a part of it corresponds to the place where mineralization containing Au was recognized in this year’s field survey.
Regarding mineralization/alteration zones in the southern part of the Pancho Arias area, alteration zones composed of sericite and chlorite were detected in Incahuasi zone, and they almost correspond to mineralization/alteration zones (where silicification and sericitization - chloritization are recognized).
It was judged that an alteration zone made up of kaolin - sericite (and jarosite), detected from the satellite image around Abra Chaní in the northeastern part of the Mina Pancho Arias, might be that of Precambrian quartz sandstone (quartzite). As a result of the field survey, an alteration zone made up of chlorite or of chlorite - sericite, detected in the southwestern part of Incahuasi, proved to correspond to granite outcrops.
In The El Pago area, the area of 4 km x 2 km (extending from east to west) in the ASTER false color (VNIR) image presents a color tone which is remarkably different from the circumference and can be recognized as a large-scale alteration zone. In the results of alteration mineral identification, sericite, chlorite, geothite and a small quantity of epidote are found in the whole area of alteration zones. Kaolin and jarosite are detected partly in the alteration zones.
In El Pago place of mineral showings, alteration zones (phyllic - argillic alteration zones and propylite zones) mainly made up of quartz - sericite - chlorite and clay mineral are distributed as mentioned in the previous section. Around the center, potassium alteration zones where potassium feldspar (±biotite) is recognized are output, and silicified zones are distributed locally. When this alteration is interpreted as overlapping of potassium alteration zones in the central part, phyllic - argillic alteration zones and propylite alteration zones in the peripheral part, among these alteration zones, phyllic - argillic alteration zones and propylite zones almost correspond to the area where sericite, chlorite, geothite, epidote, kaolin and jarosite were detected in the image.
This place of mineral showings is located about 40 km northwest of Filo Colorado, a prospecting area of porphyry copper deposits. According to satellite image analysis, it is recognized that there is distribution of a group of alteration zones, which are located sporadically in the NE - SW, direction between Filo Colorado and El Pago, and which are composed of sericite/geothite (±kaolin). Furthermore, indication of a probable alteration zone is found 4 - 6 km northeast of El Pago. However, it is difficult to identify an alteration zone by the use of the satellite image because this area is a vegetation zone. Nevertheless, that the state of outcrop where indications of hydrothermal alteration such as the above are distributed sporadically in the NNE - SSW direction could be identified will be an important guide when mineralization in this zone is considered.

In the Rachaite area, alteration zones in two places, east and west, presenting a remarkable white color tone are clearly observed in the false color image. In the color-ratio composite, strongly anomaly areas, which agree with the white parts in the false color image, are detected. In the result of alteration mineral identification by the use of the Iso-grain Model, the color tone indicating an acid alteration zone of alunite - kaolin and a sericite alteration zone is detected from the same place. The color tone representing goethite and quartz is recognized there.
Both of these two white alteration zones extending from south to north agree with areas subjected to strong white argillization (mainly composed of quartz/opal - sericite - sericite/montmorilonite mixed-layer mineral and accompanied by kaolin, jarosite, chlorite, alunite, etc.) and limonitic alteration in dacite.
In the Cerro Galán area, several alteration zones have been detected from Galán caldera by LANDSAT TM and ASTER image analyses; the main alterations run along the caldera wall. From the result of alteration mineral identification, an alteration zone of 4 km in diameter on the northwest wall part of the caldera is judged to be an alteration zone composed of alunite, sericite and goethite with kaolin as the main. Five-hundred meters south of this alteration zone, a small-scale alteration zone group representing distribution of alunite and kaolin is detected, and indication of alteration of alunite - kaolin - sericite is recognized in the western part of Laguna Diamante.
In the results of X-ray analysis of alteration samples collected in the field survey of the Cerro Galán area, alteration mineral made up of a combination of sericite, chlorite and calcite was identified in many samples. A large quantity of kaolin was detected in some of them. In addition, trace quantities of jarosite and pyrite were recognized.
Following last year, detection of alteration zones by the use of false color images, color-ratio composites and the Iso-grain Model was carried out this year. Particularly, in alteration mineral identification by the use of the Iso-grain Model, analysis of alteration mineral was made for some scenes with 12 constituents (quartz, calcite, sericite, chlorite, epidote, kaolin, goethite, jarosite, alunite, gypsum, hematite and pyrophyllite) used as a reference. As a result, we could obtain data, which will be a good guide in the detection of alteration zones in the Pancho Arias and El Pago areas, as mentioned above. The effectiveness of and future tasks regarding alteration zone detection by this technique are organized as follows:
(i) Alteration related to porphyry primary mineralization in NOA region is potassic alteration, phyllic alteration, advanced argillic alteration and propylite alteration. Of these, finding of propylite zones by the use of satellite images is a very important guide in the stage of selecting zones to be covered by the method. From this point of view, it can be considered as an advance in development of technique that the scope of propylite (chlorite - epidote distribution) could be detected from the Pancho Arias and El Pago areas by ASTER image analysis in this survey. (ii) Argillic alteration zones such as NOA region can be easily recognized in false color images in dry areas with a little vegetation. It is, however, effective for analysis of alteration zones that constituents
- 321 -
of those alteration zones can be identified by mineral identification technique. It is considered as a noteworthy result that, particularly, chlorite, sericite, kaolin and alunite could be detected as clay mineral. (iii) Regarding iron gossan in the superficial part of weathered zones, it is also worthy of notice that the degree of limonitic alteration could be detected sensitively. Hematite and jarosite could be also identified to some extent. (iv) As a future task, it is desired to develop a method of identifying potassium feldspar and biotite. If it becomes possible, the way for detection of potassic alteration zones, which are often outcrop in the central part of porphyry mineralization, will be opened. (v) In addition, it is one of the noteworthy results of this investigation and analyses that, with the merits of multi-band and highly-precise ASTER image data utilized, useful data for estimation of the tectonic line which had controlled mineralization/alteration could be obtained by extracting small-scale but important alteration zones.
(3) Structural control of the mineralization and hydrothermal alteration [Structural control of porphyry copper and epithermal gold deposits]
As is pointed out in last year’s report, it is recognized that distribution of porphyry and epithermal deposits in NOA region has a relationship from viewpoints of time and space with areas where Neogene volcanic rocks are intensively distributed. (See Chapter 6. Consideration - 6.1. Characteristics of tectonic structure and mineralization, and control of mineralization in last year’s report.) • A magmatic arc of the Miocene to Pliocene accompanied by porphyry copper deposits such as Los Pelambres and el Teniente in Chile is widely distributed over the whole Andes mountains around the Chile - Argentina boundary (called CVZ (Central Volcanic Zone): Ramos, 2000 etc.). NOA region is located in the east side of this magmatic arc, and four distribution areas of volcanic rocks are observed extending in the SE direction in an arm-like shape branching away from the magmatic arc itself spreading from south to north. Such arm-shaped distribution areas of Neogene volcanic rocks are called Arm Nos. 1 to 4 (volcanic rock arms), in order from the north. These arms agree with known wide-area NW-SE oriented lineaments or their extension part, respectively. According to the results of air-borne magnetic survey, the distribution of these arms shows good agreement with the short-wave magnetic anomalyl area. This is considered to indicate that it corresponds not only to effusive facies of volcanic rock but also to intrusion facies. In NOA region, several calderas of the Neogene are distributed, including Galán caldera whose scale is exceptional in the world. Volcanic activities of each arm are accompanied by such strong eruption activity that is characterized by formation of large-scale resurgent calderas and/or wide-area distribution of ignimbrite. • Regarding distribution of porphyry deposits in NOA region, Cerro Redondo (porphyry gold deposits) is located in Arm No. 1, Pancho Arias (porphyry copper/molybudenum deposits) and
- 322 -
Organullo (porphypric gold deposits) are in Arm No. 2, Taca Taca (porphyry copper deposits) and Inca Viejo (porphypric copper/gold deposits) lie between Arm Nos. 2 and 3, El Arisar (porphpyric copper deposits) is in Arm No. 3, and Bajo de la Alumbrera (porphpyric copper/gold deposits), Agua Rica (porphypric copper deposits) and Filo Colorado (porphyry copper/gold deposits) are located in Arm No. 4. • Regarding epithermal deposits, Chocaya exists in Arm No. 1, Esperanza, Concordia, Bajos de Incachule and Organullo are located in Arm No. 2, Centenario lies between Arm Nos. 2 and 3, and Farallon Negro, Alto de la Blenda and Carmen deposits exist in Arm No. 4.
Distribution of Neogene Tertiary volcanic rocks from the northwestern part of Argentina to the northern part of Chile and locations of the four arms are shown in Fig. II-4-3-2-3-1.
Four arms representing Neogene volcanic activity in NOA region are distributed along NW-SE oriented lineaments crossing the range of the Andes Mountains, as mentioned above. The main ones of these lineaments have been already named, such as Calama-Olacapato-El Toro lineament and Archibarca lineament (Salfity, 1985, Hongn et al., 2002 etc.). These lineaments are interpreted as strike-slip faults (shifted to left) representing the shear belt accompanying subduction of Nazca plate, and are estimated to represent deep fracture, which controlled the rise of magma. Along these lineaments, volcanic activities were actively generated during the Miocene to Pliocene period. Fig. II-4-3-2-3-2 shows the regional geologic structure of NOA region and the north region of Chile adjoining the region.
As mentioned above, in NOA region, mainly magmatic activity of Miocene to Pliocene calc-alkaline volcanic rock is actively generated along the NW-SE oriented tectonic line in particular. The magmatic activity is accompanied by porphyry and epithermal mineralization/alteration.
As structural factors, which control calc-alkaline magmatic activity of the Neogene and mineralization/alteration accompanying them, the presence of these NW-SE oriented shear belts can be mentioned. Together with these, in Chile, the presence of the line structure crossing them, in other words, the importance of the crossing part of two tectonic lines, is pointed out. (It is pointed out by Richards (2000) and others that porphyry deposits in Chile, such as Quebrada Blanca, El Abra, Chuquicamata, Zaldivar, Chimborazo, Spence, La Escondida, El Sadovador and Potrerillos, are distributed along the Domeiko fault parallel to the subduction zone of Nazcaplate, and there is the tendency that deposits concentrate in the part of crossing an NW-SE oriented fault). Then, the possibility that such a structural factor exists is examined regarding NOA region below.
[Characteristics of the structural control of porphyry copper deposits] In the Pancho Arias area in NOA region, where field survey was carried out this year,
mineralization zones and hydrothermal alteration zones, such as the Mina Pancho Arias (Mina Vizcacheral), Las Burras, Incahuasi Norte and Incahuasi Sur, are distributed in the NNE-SSW direction over ten or several kilometers. As mentioned above, The Pancho Arias area is located in the
- 323 -
volcanic rock distribution area of Arm No. 2, and it corresponds to the extension part of El Toro lineament as a shear belt of the Miocene to Pliocene. Porphyry mineralization/alteration in Pancho Arias zone is closely related to intrusion of monzonitic or dacitic porphyry of the Miocene. (See the section stating results of the field survey.) Ten rock bodies of acidic intrusive rock of the Miocene are exposed in this zone, and run in the NNE-SSW direction generally. These intrusive rocks correspond to acidic igneous activity of the Neogene in the east end part in the scope of El Toro lineament. That is, it can be interpreted that, in this zone, porphyry mineralization/alteration is/are controlled by activity of Miocene acid intrusive rock governed by a line structure in the NNE-SSW direction, which crosses it within the scope of Arm No. 2.
As for the El Pago area, because detailed geological investigation of the zone has not been carried out, its tectonic structure is not clear, unlike the Pancho Arias area. Characteristics of mineralization/alteration in the El Pago area based on the existing geological materials are as follows: (1) the El Pago area is in Arm No. 3 together with El Alisar, and it is located in the extension part of Archibarca lineament. Although details of mineralization have not been clarified, it is considered to be related to andesite or dacitic intrusive rock of the Neogene (or Miocene?). (2) About 40 km south of the El Pago area, porphyry deposits exist, such as Agua Rica and Filo Colorado (belonging to Arm No. 4). These are assumed to be formed in relation to activity of Farallón Negro composite volcanic rocks of the Miocene. (3) Deposits/mineralization zones such as the El Pago, Filo Colorado and Agua Rica run in a linear form along the direction of Sierra del Aconquija extending in the NE-SW direction. In the middle part and the extension part of them, alteration zones have been detected by ASTER image analysis.
According to the results of last year’s investigation of El Alisar zone, porphyry copper mineralization accompanies activity of El Alisar volcanic rocks/hypabyssal composite rocks (the result of age determination of rhyolite which composes a part of them = 8.0±0.2 Ma) similar to Farallón Negro composite volcanic rocks. Geological data with which porphpyric mineralization in the El Pago area and mineralization in the El Alisar area is considered to belong to a sequence of the same phenomenon has not been obtained. However, the presence of mineralization/alteration zones which continue sporadically from the El Pago area in the SSW direction is considered to indicate that the El Pago deposit are closely related to Filo Colorado and Agua Rica deposits. Thus, it is considered that porphyry mineralization/alteration in the El Pago, Filo Colorado and Agua Rica areas was controlled by the NE-SW oriented tectonic line crossing in the direction of distribution of Arm Nos. 3 and 4.
In this way, it seems possible that structural elements similar to those recognized in Chile also exist in the field of porphyry mineralization in NOA region. It is the presence of "line structure in the NNE-SSW direction which crosses it within the scope of belonging to Arm No. 2" seen in the Pancho Arias area, and interpretation that Miocene acid intrusive rock which is governed by this presence and porphyry mineralization/alteration accompanying its intrusive igneous activity. "Arrangement of deposits and mineralization/alteration along the NE-SW oriented tectonic line crossing in the direction of distribution of Arm Nos. 3 and 4" in and around the El Pago area (Sierra
- 327 -
del Aconquija region) is also interpreted to imply the importance of a tectonic line crossing the shear belt accompanying plate activity indicated by the distribution direction of the arms. It is considered that, from these points of view, it is helpful for selection of potential prospecting areas of porphyry deposits to carry out work to find shear belts and tectonic lines crossing them and, in addition, to extract alteration zones by the use of the new technique mentioned above.
[Characteristics of the structural control of epithermal gold deposits] The Rachaite area is in the distribution of Neogene volcanic rock belonging to Arm No. 1,
and mineralization/alteration zones are considered to be made by the hydrothermal system formed in the relatively early stage (8 - 9 Ma) of dacitic Coranzuri composite caldera activity that occurred in the middle to upper Miocene. Mineralization/alteration zones in the Rachaite area are located inside the ring structure interpreted as the caldera wall, and they are composed of two parallel alteration zones extending in the N-S direction generally. Main lead/zinc veins in the Rachaite area are those with an almost N-S strike. From such a state of outcrop of deposits and alteration zones, it is considered that epithermal mineralization/alteration accompanies dacitic caldera volcanic activity of the Miocene and is controlled by N-S oriented cracks near the caldera wall.
Epithermal alteration zones in the Cerro Galán area are distributed mainly on the inside wall of dacitic Galán caldera formed in the Neogene. Galán caldera is a composite caldera whose scale is exceptional in the world, covering an area of 40 km from south to north x 25 km from east to west. It is located on Archibarca lineament representing a NW-SE oriented shear belt. As a Neogene volcanic rock distribution area, it belongs to the scope of Arm No. 3. From the fact that, in the distribution area of epithermal alteration zones, there are caldera faults and lineaments estimated to be radial faults crossing them, it is considered that there is the possibility that alteration zones in this zone were formed by the rise, along the fault crossing part, of hot water accompanying volcanic activity when the caldera structure was formed. As the structure that controlled the field of generation of epithermal mineralization, both in the Rachaite and Cerro Galán areas, the fault structure on or around the caldera wall accompanying formation of the caldera serves as a passage for hot water in the hydrothermal activity stage after the formation of the caldera.

Chapter 5 Discussion
5-1 Mineralization and potentiality of existing mineral deposits
Tectonics in the northwestern part of Argentina was, as mentioned in Chapter 3, Part I, formed
by collision and accretion of micro continents on the southwest margin of Gondowana continent of the
upper Precambrian to the lower Paleozoic, and by cordillera type orogeny due to subduction of the
ocean plate from the west side, which has continued since the upper Paleozoic.
In the geological body of the Precambrian to the Quaternary developing in this area, there are
deposits each of which are closely related to the history of tectonics development and have
characteristics of its own age. Deposits of the Ordovician system, whose potential is considered to be
high are SEDEX-type lead and zinc deposits and volcanogenic massive sulfide deposits, while those
of the Neogene system are porphyry type copper and copper/gold deposits and epithermal gold
deposits.
The El Aguilar deposit classified as SEDEX type lead and zinc deposits exists in the lower
Ordovician Lampasar formation which is passive margin deposits to the eastern side of the north of the
survey area. The La Colorada deposit classified as volcanogenic massive sulfide deposit exists in the
Ordovician magmatic arc to the west of the north of the survey area.
The porphyry type copper and copper/gold deposits and the epithermal gold and silver deposit
are limited to the areas of four Neogene volcanic rock zone extending like armed shape in a SE
direction from the Chilean border, near intrusive rocks between the volcanic rock zone, and on its
extensions. The porphyry type copper and copper/gold deposits develop around Farallon Negro, which
is located in one of the volcanic rock zone of relatively advanced erosion, in the neighborhood of Inca
Viejo, which is on the periphery of intrusive rock area between the volcanic rock zones, and to the
west of Tucuman, which is the zone's extension. On the other hand, the alteration zones related to the
epithermal gold and silver deposit tend to exist at a less eroded area, such as those near the Agua
Caliente caldera.
5-2 SEDEX/VMS type deposits
For exploration of SEDEX type lead/zinc deposits, there are only a few clues because deposits
of this type generally have a weak alteration halo differently from other epithermal deposits. In order
to explore a similar type that provides few clues to the exploration, it is desirable that the
characteristics and formation restricting conditions of El Aguilar deposit (including Esperanza deposit)
be correctly determined and that exploration factors drawn from those characteristics and formation
restricting conditions and general exploration factors of world’s major SEDEX-type lead/zinc deposits
be deductively applied to a similar neighboring geological environment. There is a similarity that the
typical SEDEX type lead/zinc deposits in the world are formed in small-scale sedimentary basins with
- 329 -
anoxic environments in large-scale sedimentary basins such as passive margin (for example, Sangster
and Macintyre, 1983; Lydon, 1995). Sureda (1999) inferred that El Aguilar deposits were formed in
Padrioc Basin of the third order spreading north and south from El Aguilar to Pumahuasi. From the
viewpoint of the regional scale, it is desirable to re-analyze (re-examine) sedimentary basins in terms
of positioning of El Aguilar deposits in the Ordovician system, based on the existing sedimentological
data.
In the analysis carried out during the Phase I, drilling core of El Aguilar deposit was
provided by Compania Minera Aguilar S.A. and an attempt was made to identify the ore horizon
as well as hanging wall and foot wall through the statistical analysis of the chemical composition
of the drilling core’s mudstone. It was found as a result that litho geochemical analysis can
discriminate the differences in the chemical composition between hanging wall and footwall.
The similar ore horizon found through the aforementioned study to identify the hanging wall and
foot wall of the SEDEX type Pb/Zn deposit, stretches in the N-S direction in the environs of El
Aguilar deposits including Rio Grande one, is the most promising area.
Meanwhile La Colorada deposits distributed on the west side of the area in the Ordovician
system were regarded as volcanogenic massive sulfide deposits because the deposits were
accompanied by volcanic rocks in the vicinity, because filling texture with sulfide minerals in the
space of brecciated volcanic rock is observed and because the content of copper is higher than those of
lead and zinc compared with typical SEDEX deposits. Although the control factor of this deposit are
not clear, if it was formed accompanying volcanic activity, it is expected that similar deposits exist in
the whole magmatic arc of the Ordovician on the west side in the north part of the survey area.
The study of the Phase II, as one of the methodology to understand sedimentary basin of
SEDEX, has increased a possibility that a horizon similar to a known SEDEX deposit horizon can be
traced mainly from geochemical characteristics. Based on this study, it was shown that Discriminant
Analysis and principal component analysis can identified litho geochemical feature of SEDEX
and VMS. On the basis of this, it seems possible to identify the distribution of SEDEX or VMS
deposits occurrence or regional sedimentary basin structure, by analyzing geochemical
characteristics of the lower Ordovician System that has not been fully surveyed. Those findings will be
valuable basic information in order to carry forward the SEDEX deposit exploration in the future.
In terms of the ore forming age, the ore horizon of El Aguilar is considered to lower
Ordovician of Lampasar formation with the evidence of mega fossils. However, recent discovery of
conodont and olistostrom made reconsider traditional theory of ore forming age. Therefore
stratigraphic classification using high-resolution microfossils (such as conodonts and radiolarian) of
the Early Paleozoic Era is desired. It will be necessary to collect conodonts directly from mudstone as
well as from calcareous rock because calcareous rock that preserves conodonts in good condition is
outcropped only in small quantities. Furthermore in the area, which has olistostrom, it is also
- 330 -
necessary for accurate geochemical and paleontrogical study about olistolith and matrix rocks
respectively.
On the other hand, the microfossil study, which is an important factor for identifying the
stratigraphy related to the SEDEX type deposits, was carried out. As a result, Rossodus tenuis
(Miller, 1980) and Drepanoistrodus sp. was identified accompanied with gastropods and
brachiopods in the Santa Rosita limestone, lower of the Santa Victoria group located at the
vicinity of the Santa Victoria town. These fossils indicate the age of the area is Tremadocian in
lower Ordovician system (absolute age approximately 487-489 m.y.).
For recommendation in future exploration, in concrete, it is necessary to apply the litho
geochemical method, in a wider range, to a northern extent including Rio Grande where El Aguilar
deposit is included, sulfide layers were discovered in the ground truth checking of the previous year, in
order to clarify the ore horizon. It is also necessary to identify ore horizon in a similar way from a
north-south extent including Santa Rosa and La Cienaga prospects.
A massive sulfide deposit was discovered in La Colorada deposit through drilling carried out
by Pacific Rim. It is essential to determine the characteristics of this deposit, using the core samples.
As in the case of El Aguilar deposit, a lithological and geochemical study using ore host rock to
extract ore horizon is required. Existence of hydrothermal alteration zone is expected on the hanging
wall and footwall of a volcanic massive sulfide deposit; therefore, its confirmation is needed. The
tectonic setting of La Colorada deposit differs from that of El Aguilar deposit in that the occurrence of
calc-alkali volcanic rock is seen. Little is known about its genesis. In the light of the characteristics of
La Colorada deposit determined up to now, it is desired that the genesis environment be studied with
the help of existing data, from the viewpoint of a volcanic activity setting and formation of a massive
sulfide deposit.
5-3 Porphyry copper and epithermal type deposits
Miocene to Pliocene magmatic arcs developed near the border between Chile and Argentina.
In this area, four volcanic rocks zone extend like an arm shape in the NE-SE direction from this north
south trending main magmatic arc. This report tentatively called them No.1 to No.4 arms for
convenience. Distribution of porphyry type copper and copper/gold deposits and epithermal gold
deposits are restricted in these four arms. Therefore, these four zones can be fundamentally mentioned
as highly potential zones. Particularly, Arm No. 4 has some porphyry type deposits and alteration
zones such as Bajo de la Alumbrera, Bajo de la Agua Tapada, and Filo Colorado. Although
distribution of volcanic rocks is very small near Inca Viejo halfway between Arms No. 2 and No. 3, it
is assumed from the results of airborne magnetics that the potentiality of intrusive rocks exists in the
shallow part of the vicinity. In addition, mineralized zones including Inca Viejo, Diablillos, Condor
Yacu and Centenario are known. Therefore, even though the distribution of volcanic rocks is very
- 331 -
small, these zones can be regarded as those with high potential for the presence of porphyry type
copper and copper/gold deposits and epithermal gold deposits.
In the SE tending extension of each arm, small-scale intrusive rocks are scattered, which are
not expressed on a small-scale geological map. Porphyry type copper and copper/gold mineralization
are observed inside and outside those rocks. This mineralization corresponds to Agua Rica deposits of
Arm No. 4, El Alisal and El Pago of Arm No.3 and Panco Arias alteration zone of Arm No. 2. These
have been also extracted as alteration zones in the satellite image analysis.
Regarding porphyry type copper and copper/gold deposits, the potential for the existence of
deposits is thought to be high, as mentioned above. Substantially minute investigations have been
already carried out, and room for exploration is considered to exist in the SE tending extension of each
arm.
In three north arms of the four, there are resurgent calderas accompanied by ignimbrite, and
erosion of volcanic body has not advanced so much yet. Therefore, if porphyry type copper and
copper/gold deposits are formed in these volcanic arms, those deposits exist in the deeper level and
cannot be the object of exploration.
It is considered that epithermal gold deposits are at the favorable level of erosion. In particular,
Rachaite and Incachule alteration zones are obviously inside the caldera wall and can be regarded as
products of the volcano-hydrothermal system. A similar presumption can be applied to alteration zone
on the east side of Galan caldera extracted from the satellite image analysis.
In order to clarify the alteration zone, the geochemical and other features of each survey
areas that located in the four zones (arms) which are object of the prospecting of porphyry
copper and epithermal deposits, the Phase II study has carried out field survey and collection of
samples, followed by laboratory work consisting of geochemical analysis, X-ray diffraction, thin
section identification. At this stage, the geochemical analysis has not revealed any significant ore
showing that suggests economic value in four places selected as a survey target area of this fiscal year.
The feature of a typical porphyry copper type alteration zone, however, was clarified in El Pago, and
similar cluster of alteration with NNE-SSE trend near to El Pago, which may be a promising candidate
for exploration, depending on a future survey.
With respect to porphyry copper type deposits and copper/gold deposits, it can be hardly said
that a sufficient survey has been made on the mineral showing in a small-scale Neogene Period stock
in the bed rock located in the volcanic rock arm extension because the mineral showing is far away
from the major volcanic rock distribution. The alteration zone group extending in the NE-SW
direction from the Agua Rica and Filo Colorado prospects 40 km south-southwest of El Pago to El
Pago shows characteristics similar to those of an alteration zone. Further study will be required for
some alteration zones. Also, at an extension to the alteration zone group is situated El Arisar prospect
where a mineral showing dominated by structural factors is very likely to occur. For this reason, it is
- 332 -
desired that the characteristics, extent, geophysical feature, etc. of the neighboring alteration zones be
determined through a more detailed satellite image analysis, regional geophysical exploration.
With respect to epithermal gold/silver deposits, a lot of ore showings are known in the
volcanic rock extension zone. The image analysis of Phase I and the ground truth checking revealed
that an argillic alteration zone occurs with base metal on the wall of a resurgent caldera such as
Rachite, Incachule, and Pan de Azucar or on the wall of a ring structure. Large-scale alteration zones
in the Rachite and Cerro Galan areas situated on the margin of the caldera were surveyed in this fiscal
year, however no significant mineral showing was found near the ground surface. These large-scale
alteration zones, however, are likely to represent a shallow part of the hydrothermal system; therefore,
the occurrence of an epithermal gold deposit in the depths cannot be ruled out. A technique for
estimating the deeper level of hydrothermal system such as isotope geochemical study is needed for
future exploration.

PART III: CONCLUSION AND RECOMMENDATION
Chapter 1 Conclusion Analysis of the existing data including preparation of the mineral deposits database, satellite
image analysis of two ASTER data, geochemical analysis of the stream sediments, and field survey
work have been carried out during the current fiscal year, that is the final year of the two-year
survey program under way. SEDEX type Pb/Zn deposits, porphyry copper type Cu and Cu/Au
deposits and epithermal Au deposits have been targeted in the work step referring to the existing
data analysis, because they are deposit types with economic merits.
The number of areas object of field survey totaled eight, with four areas (Aguilar mountain
range, Pumahuasi, Santa Victoria mountain range and La Colorada) surveyed with the object of
prospecting SEDEX/VMS type deposits and other four areas (Pancho Arias, Rachaite, Cerro Galan
and El Pago) with the object of prospecting porphyry Cu and epithermal deposits.
(1) SEDEX type lead/zinc deposits and volcanogenic massive sulfide deposits
In the analysis carried out during the Phase I, drilling core of El Aguilar deposit was
provided by Compania Minera Aguilar S.A. and an attempt was made to identify the ore horizon as
well as hanging wall and foot wall through the statistical analysis of the chemical composition of the
drilling core’s mudstone. Based on this study, it was shown that Discriminant Analysis and principal
component analysis can identified litho geochemical feature of SEDEX and VMS
The following facts related to the mineralization have been found as a result of the
geochemical analysis.
・In Aguilar mountain range area the occurrence of the SEDEX type mineralization (high degree of
correlation with Ag, Sb, Hg, Zn, Cd, Pb, S and Au) has relation not only with Esperanza deposit,
which is a typical of SEDEX type mineralization, but also with other places such as Aguilar deposit,
Oriental prospecting area, Pirita prospecting area, etc.
・Furthermore, in other prospecting area besides Esperanza deposit, such as Aguilar deposit and the
prospecting area surrounding it, other mineralization represented by Colorada deposit (high degree
of correlation with Bi, Au, W, Fe and Ba) overlaps.
・On the other hand, the intervention of a mineralization rather related to La Colorada deposit than
the SEDEX type mineralization is found in Rio Grande prospecting area which is located
approximately 3 km to NE of the Esperanza deposit.
・ Since geochemical factors of the SEDEX type mineralization are found, although not
conspicuously, in Santa Victoria mountain range area, the possibility of occurrence of the SEDEX
type mineralization can not be rejected.
- 335 -
・As a matter of course, the mineralization represented by La Colorada deposit is markedly
developed in La Colorada area (second principal component). Since a third principal component
suggesting the occurrence of the SEDEX type mineralization was found as a result of a local
principal component analysis covering exclusively La Colorada deposit drilling core, it may safely
be said that the possibility of existence of the SEDEX type mineralization in this area, including
Limeca, still persists.
In the meanwhile, the sulfur isotopic ratio of lead in vein-type lead, zinc and barite deposits
in the area with distribution of the Ordovician system differ from those of El Aguilar deposits.
Therefore, the origin of sulfur of these deposits is considered to be different.
2) Porphyry type copper and copper/gold deposits
Miocene to Pliocene magmatic arcs developed near the border between Chile and Argentina.
In this area, four volcanic rocks zone extend like an arm shape in the NE-SE direction from this
north-south trending main magmatic arc. Distribution of porphyry type copper and copper/gold
deposits and epithermal gold deposits are basically restricted in these four zone. Therefore, these
four zones can be fundamentally mentioned as highly potential zones.
ASTER image analysis had revealed detailed classification of alteration zone, which is
impossible with conservative satellite sensors in this survey. As results, it is found that the outlined
alteration zones are distributed more in four zones where Tertiary volcanic rocks extend NE and SE
and in the extension of these zones. The major tectonic line is also along these NE-SW trending
zones of Tertiary volcanic rocks and in their extension (Fig.II-3-3-2).
In order to clarify the alteration zone, the geochemical and other features of each survey
areas that located in the four volcanic rock zones which are object of the prospecting of porphyry
copper and epithermal deposits, the Phase II study has carried out field survey and laboratory work.
At this stage, the geochemical analysis has not revealed any significant ore showing that suggests
economic value in four areas selected as a survey target area of Phase II. The feature of a typical
porphyry copper type alteration zone, however, was clarified in El Pago, and similar cluster of
alteration with NNE-SSE trend near to El Pago, which may be a promising candidate for exploration,
depending on a future survey.
Furthermore, the most south part of volcanic rock zone (No.4 arm) has some porphyry type
deposits and alteration zones such as Bajo de la Alumbrera, Bajo de la Agua Tapada, and Filo
Colorado which were the target area of Phase I survey, and although distribution of volcanic rocks is
very small near Inca Viejo, it is assumed from the results of airborne magnetics that the potentiality
of intrusive rocks exists in the shallow part of the vicinity. In addition, mineralized zones including
Inca Viejo, Diablillos, Condor Yacu and Centenario are known. Therefore, even though the
- 336 -
distribution of volcanic rocks is very small, these zones can be regarded as those with high potential
for the presence of porphyry type copper and copper/gold deposits and epithermal gold deposits.
- 337 -
Chapter 2 Recommendation for future survey
1) SEDEX type lead/zinc deposits and volcanogenic massive sulfide deposits
In order to explore a similar type of El Aguilar deposit, it is desirable that general
exploration factors of SEDEX-type lead/zinc deposits be deductively applied to NOA area.
Specifically, from the viewpoint of the regional scale, it is desirable 1) to re-analyze sedimentary
basins in terms of positioning of El Aguilar deposits in the Ordovician system, based on the existing
sedimentological data, 2) to apply the litho geochemical method to lower Ordovician system for
tracing SEDEX/VMS horizon, 3) to classify detailed stratigraphy using high-resolution microfossils
(such as conodonts and radiolarian) of the Early Paleozoic Era, to collect conodonts directly from
mudstone, and 4)to carry out accurate geochemical and paleontrogical study about olistolith and
matrix rocks respectively. Furthermore it is also necessary to confirm presence of a hydrothermal
alteration in La Colorada area, which is expected on the hanging wall and footwall of a volcanic
massive sulfide deposit
2) Porphyry type copper and copper/gold deposits
With respect to porphyry copper type deposits and copper/gold deposits, it can be hardly
said that a sufficient survey has been made on the mineral showing in this survey area. For future
exploration, it is desirable to carry out more detailed satellite image analysis, regional geophysical
survey in order to clarify the distribution and geophysical feature of alteration zones that are known
in volcanic rock zone and on its extension or are discovered by satellite analysis of this survey
With respect to epithermal gold/silver deposits, especially large-scale argillic alteration zone
located on the wall of a resurgent annular structure which are considered as corridor of hydrothermal
water, a technique for estimating the deeper level of hydrothermal system such as isotope
geochemical study is needed for future exploration.

STUDY OF 5 CONODONT SAMPLES
Direction of study: Dr. Mario A. Hünicken. Present report: Dr. Guillermo L. Albanesi.
Córdoba, Argentina
Introduction Five carbonate samples were processed in search of conodonts. These samples (28506 g in total) were completely digested by conventional acid etching techniques, using either 10 % acetic or formic acid. The heavy fraction of insoluble residue was separated by means of heavy liquid (bromoform). This fraction was examined through stereoscopic binocular, and microfossils were recovered by picking techniques (see Stone, 1987, for reviews on conodont laboratory methodologies). Conodonts and associated microfossils were mounted on slides for study and final storage. Record of conodont samples and results 1 Date: October 27, 2002. District: El Aguilar. Locality: Despensa Creek. Sample: L1 (overlying interval with olistoliths). Formation: Lampazar?, Saladillo? Mass: 8418 g. Lithology: Calcarenite, interbedded with shales and fine green sandstones). Sample: L2 = 7 m above L1. Mass: 4800 g. S 23º 15´40,7´´. W 65º 42´26.3´´. Micropaleontological result: both samples barren of fossils. 2 Date: October 27, 2002. District: El Aguilar. Locality: Río Grande Creek – Section with SEDEX . Sample: L3 .
Mass: 7573 g. Formation: Lampazar?, Saladillo? S 23º 07´49´´. W 65º 41´16´´. Micropaleontological result: barren of fossils. Comment: It is significant to note that a correlative level, in same study area, studied by Rao and Flores (1998) yielded a conodont assemblage with the key species Paltodus deltifer (Lindstöm, 1955) of the eponymous biozone, which allowed for dating the mineralized interval as Upper Tremadoc (Lower Ordovician) in age. 3 Date: October 28, 2002. District: El Aguilar. Locality: Quebralaite Creek. Sample: A1. Mass: 3615 g. Sample A2 = 5 m above A1. Mass: 3373 g. Formation: Saladillo? Lithology: Calcarenite nodules, 5-10 cm thick, in shales and bluish fine sandstones. Latitude: S 23º 17´39.9´´. Longitude: W 651 46´38.6´´. Altitude: 3600 m. Micropaleontological result: barren of fossils . ______________________________________________________________ 4 Date: October 8, 2002. District: El Aguilar . Locality: Despensa Creek. Sample: AO2SX011. Mass: 3200 g. Formation: Lampazar? Lithology: Limestone. Latitude: S 23º 15´37.8´´. Longitude: W 65º 42´36.7´´. Micropaleontological result: barren of fossils. ______________________________________________________________
5 Date: October 31, 2002. District: Santa Victoria. Sample: AO2TK037. Mass: 5700 g. Formation: Santa Rosita? Lithology: Limestone. Latitude: 22º 14´51.1´´ . Longitude: 64º 57´43.5´´. Altitude: 2,302 m. Micropaleontological result: After complete digestion and recovering of fossil remains by picking from undisolved residue, three elements pertaining to two conodont species were collected (Figs. 1, 2). Associated fossils include undetermined gasteropods and inarticulate brachiopods (Fig. 3). Following conodont species are determined, and consequent biochronology is established. Conodont taxonomy
Genus Rossodus Repetski and Ethington, 1983 Type species: Rossodus manitouensis Repetski and Ethington, 1983
Rossodus tenuis (Miller, 1980) Fig. 2a-b
Synonymy 1980 – Utahconus tenuis Miller, 1980, p. 36-37, pl. 2, figs. 5-7, text-fig. 4T. 1994 – Rossodus tenuis Ji and Barnes, 1994, p. 56-57, pl. 17, figs. 10-19. 2002 – Rossodus tenuis Pyle and Barnes, 2002, p. 102-103, pl. 13, fig. 21-26 (cum syn.). Material: 1 a element, 1 b element. Remarks: Diagnosis of the species was emended by Ji and Barnes (1994) from original designation given by Miller (1980), and the apparatus reconstruction was recently reconsidered by Pyle and Barnes (1994). These authors provide a detailed description of every morphotype (a, b, and c) that compose the species apparatus. Current collection includes a and b elements. Figure 2a-b illustrates the b element, which is asymmetrical, bilaterally compressed, and presents sharp anterior and posterior margins of the cusp. Both faces of cusp show a faint carina. The base is
slightly extended to posterior, with a flared postero-basal margin. Basal cavity is triangular in lateral view, with an apex directed to the anterior margin. Occurrence and age: Rossodus tenuis and Rossodus manitouensis zones sensu Pyle and Barnes 2002, or Cordylodus angulatus Zone, the second conodont biozone of the Ordovician System from other schemes of North America (e.g., Ross et al., 1997). Lower (but not lowermost). Tremadoc Stage of the global Lower Ordovician Series. About 487-489 million years (Cooper, 1999).
Genus Drepanoistodus Lindström, 1971
Type species: Oistodus forceps Lindström, 1955
Drepanoistodus sp. Fig. 1a-b
Material: 1 Sb element. Remarks: One element characteristic of the genus Drepanoistodus was recovered. Apparently, the morphotype corresponds to the Sb position in the apparatus of a new species. The illustrated specimen is distinguished by a narrow groove on the inner flank that runs along the anterior margin, as well as a proclined cusp, and oval basal margin. The absence of diagnostic morphotypes, such as the M element, precludes specific designation. Nota Bene: The Color Alteration Index of registered conodonts is ca. 3, which indicates up to 200ºC of overburden paleotemperatures for the bearer strata (Epstein et al., 1977).

PALYNOLOGICAL STUDY OF 19 SAMPLES
Present report: Dr. Eduardo G. Ottone INTRODUCTION The aim of this study is to provide a biostratigraphic basis for facies and pale environmental interpretations. Laboratory procedures followed conventional practices. Between 20 and 25 grams of each sample were processed. Following crushing, carbonates and silicates were removed by treatment with hydrochloric and hydrofluoric (70%) acids. Residues were sieved on 200 µm and 25 um meshes and mounted in unstained glycerine jelly. Slides were examined under a Leitz Orthoplan binocular microscope. CONCLUSIONS All samples are palynologically barren. There is almost no kerogen in the studied samples. The list of analyzed samples is the following one: 1) Rock type: shale/SEDEX Location: Río Grande, Sierra El Aguilar, Cordillera Oriental, Jujuy Province. 2) Rock type: shale.
