1.0 SUMMARY
This report details the results of a 39-hole reverse circulation overburden drilling/heavy mineral geochemical sampling program conducted by Golden Rule Resources Limited on its Aabarock property option in Joutel and Douay Townships of northwestern Quebec. The drilling was performed with the objective of evaluating the gold potential of the property based on the assumption that the geological setting is similar to that at Inco's nearby Douay Gold Zone. Total
project costs averaged $61.36 per metre.
The Golden Rule drill area is underlain by east-southeast trending Archean
clastic metasediments, intermediate to felsic metovalcanics, iron formation and a
synvolcanic quartz-feldspar prophyry intrusion. The rock units are vertical to steeply north dipping and younging and form the upper part of a central complex-type volcanic succession. The metamorphic grade is subgreenschist to lower
greenschist faces. Two stratigraphically controlled shear zones and one cross-
cutting fault are evident.
Weakly anomalous bedrock gold values, coincident with widespread,
dessiminated Fe/Mg carbonate alteration that is probably syngenetic, were
obtained from metasediments in the eastern portion of the property. A silicified,
Fe/Mg carbonate-veined shear zone intersected in Hole 19 contains 10 to 15 percent very fine disseminated pyrite and of 205 ppb gold.
The overburden in the drill holes averages 35.6 metres in depth and consists
of Late Wisconsinan and Holocene age strata; older units were unprotected during
the Wisconsinan glaciation because the area is topographically elevated. The direction of Late Wisconsinan ice flow was south-southeast and Matheson Till
deposited by this ice forms a nearly continuous horizon across the property. The
only exception is at the east end of the drill area where the till is supplanted by the
esker-like Harricana Interlobate Moraine. The till is in contact with and is largely derived from bedrock which makes it an excellent geochemical sampling medium. Sand, silt and clay units deposited in Lake Ojibway overlie the till and in turn are capped by Holocene accumulations of peat.

The gold background of the Golden Rule concentrates is within the normal northern Abitibi Belt average. Twenty-eight of twenty-nine detected heavy mineral gold anomalies are caused by the nugget effect and are individually of no significance although collectively they appear to coincide with broad bedrock gold anomalies. The only notable heavy mineral gold anomaly (1,730 ppb) occurs in Matheson Till resting on the weakly mineralized shear zone that was intersected in Hole 19. This anomaly could represent dispersion from a nearby source but more probably results from contamination of the till by drill cuttings of the shear zone.
The eastern and south-central parts of the property appear to have the best
gold potential. Line cutting and magnetometer and VLF geophysical surveys are
incomplete in the central area and should be completed. Thirty-four additional
reverse circulation holes costing approximately $190,000 are proposed to fill in the
present coverage and delineate the mineralized shear zone near Hole 19.

INTRODUCTION
2.1
Project Outline
From February 15 to 28, 1987 Golden Rule Resources Ltd. conducted a reconnaissance-scale program of reverse circulation overburden drilling for the purpose of heavy mineral geochemical sampling on its Douay Township property option in the Abitibi Greenstone Belt of northwestern Quebec (Fig. 1 and 2). The objective of the drilling was to test the overburden for glacially dispersed gold concentrations indicative of economic bedrock mineralization that may or may not be associated with previously delineated EM conductors or magnetic anomalies.
Low tonnage, high grade gold mineralization (247,000 tons, 0.3 oz./ton) was
intersected by an Inco/Vior/Soquem joint venture program in southeastern Douay Township in 1983 (Lacroix, 1987, p.4). Airborne magnetic trends suggest that the stratigraphic horizon hosting the Douay Gold Zone crosses the Golden Rule property. This led Golden Rule to option the property.
Golden Rule contracted Heath and Sherwood Drilling of Kirkland Lake,
Ontario to perform the drilling and Overburden Drilling Management Limited
(ODM) of Nepean, Ontario to manage the program. Geologist S. Averill designed
the program in consultation with J. Hansen of Geotest Corporation and B. Evans of
Golden Rule Resources. Geologists T. Burns and P. Collins together with geotechnician B. Bark spotted, logged (Appendix A) and sampled the drill holes and
supervised the drilling.
Thirty-nine drill holes (GR-87-01 to 39) were planned and completed within the budget limits (Plan 1, in pocket). All of the reverse circulation drill holes
extended approximately 1.5 metres into bedrock. Two hundred and seventy
overburden samples and thirty-nine bedrock samples were collected (Table 1).
Heavy mineral concentrates (Appendix -B) were prepared from the overburden samples at ODM's laboratory in Nepean, Ontario. Gold particles sighted during
processing were measured to determine their individual contributions to the overall gold content of the concentrates and were classified according to their distance of glacial transport (Appendix C).

The bedrock chip samples were logged under a binocular microscope (Appendix D) and their lithologies were compared to the established Archean stratigraphy (Plan 1; Fig. 2). Subsamples of the bedrock chips and heavy mineral concentrates were analyzed for gold, arsenic, copper and zinc (Appendix E, F).
This report documents the above work and discusses results of significance.
2.2 Principles of Deep Overburden Geochemistry in Glaciated Terrain
During the Pleistocene epoch of the Quaternary period, the crowns of all ore
bodies that subcropped beneath the continental ice sheets of North America were
eroded and dispersed down-ice in the glacial debris. The dispersion mechanisms
were systematic (Averill, 1978) and the resulting ore "trains" in the overburden are generally long, thin and narrow but most importantly are several hundred times larger than the parent ore bodies. These large trains can be used very effectively
to locate the remaining roots of the ore bodies.
Because the dispersion trains originated at the base of the ice, they are
either partly or entirely buried by younger, nonanomalous glacial debris. Most
trains are confined to the bottom layer of debris deposited during glacial recession-
-the basal till. In fact, the sampling of glacial overburden for exploration purposes is commonly referred to as "basal till sampling". It is important to note, however,
that in areas affected by multiple glaciations the bottom layer of debris in the
overburden section may be only the lowermost of several stacked basal tills, and that a dispersion train may occur at any level within any one of the basal till
horizons. Consequently, the term "basal till sampling" is not synonymous with the
collection of samples from the base of the overburden section. Moreover, the term
is not strictly correct because significant glacial dispersion trains can occur in formations other than basal till.
From the foregoing statements, it can be seen that glacial dispersion and glacial stratigraphy are interdependent. Consequently, the effectiveness of overburden sampling as an exploration method is related to the ability of the
9
sampling equipment to deliver stratigraphic information from the unconsolidated
glacial deposits. In areas of deep overburden including most of the Abitibi greenstone belt in northwestern Quebec, drills must be used. Most drills have been designed to sample bedrock and are unsuitable for overburden exploration, but in
the last fifteen years rotasonic coring rigs and reverse circulation rotary rigs have been developed to sample the overburden as well as the bedrock. Both drills
provide accurate stratigraphie information throughout the hole and also deliver
large samples that compensate for the natural inhomogeneity of glacial debris.
Reverse circulation rotary rigs are much more widely used in the Abitibi than are rotasonic coring rigs. They employ dual-tube rods and a tricone bit with the
outer rod tube acting as a casing to contain the drill water for recirculation and to
prevent contamination of samples by material caving from overlying sections. Air
and water are injected at high pressure through the annulus between the outer and inner rods to deliver a continuous sample of the entire overburden section through the small inner rod (Fig. 3). The sample is disturbed but returns to surface instantly, and the precise positions of stratigraphic contacts can be identified. Full
sample recovery is possible in all formations regardless of porosity or consistency,
although sample loss due to blow-out commonly occurs in the first 1 to 3 metres of
the hole until a sediment seal is made around the outer rod.
Reverse circulation holes are normally extended 1.5 metres into bedrock.
Cuttings of maximum 1 cm size are obtained. These cuttings are used to determine the bedrock stratigraphy, structure and geochemistry and are also
compared to the till clasts to help determine ice flow directions and glacial dispersion patterns.
Most of the glacial overburden in Canada is fresh, and metals in the
overburden occur in primary, mechanically dispersed minerals rather than in
secondary chemical concentrations. While ore mineral dispersion trains are very
large, they are also weak due to dilution by glacial transport and are difficult to identify from a normal "soil" analysis of the fine fraction of the samples. Consequently, heavy mineral concentrates are prepared to amplify the primary anomalies, and analysis of the fines is normally reserved for areas where

significant post-glacial oxidation is evident. The heavy mineral concentrates are very sensitive, and special care must be taken to avoid the introduction of contaminants into the samples. On gold exploration programs, it is advantageous to separate and examine any free gold particles because most gold anomalies in heavy mineral concentrates are caused by background nugget grains that are of no interest.
2.3 Property Description and Access
The Douay property consists of 141 unsurveyed contiguous mining claims covering approximately 2,256 hectares. The property is centered approximately 45 kilometres southwest of Matagami and 15 kilometres northeast of Joutel in northwestern Quebec. One hundred and thirteen of the claims are located in west-central Douay Township and the remaining twenty-eight claims are in the east-central portion of Joutel Township (Fig. 4 and Table 2).
The claims were acquired by Ressources Minieres Aabarock Inc. early in 1984
and were optioned, later the same year, to Golden Rule Resources who can earn a 50 percent interest in the property.
Highway 109, linking Amos and Matagami, passes through the eastern arm of the property while the Joutel-Selbaie road passes within 5 kilometres of the western boundary of the property. A bulldozer was used to clear a winter truck road from the Joutel-Selbaie road to the west-central portion of the property and drill trails to individual drill hole sites (Plan 1).
2.4 Physiography and Vegetation
The Douay property lies within the northeastern portion of the Abitibi Uplands physiographic region (Bostock, 1968). This region is a north-sloping clay belt that was covered by Lake Ojibway 10,000 years ago during Late Wisconsinan

ice withdrawal. The southern boundary of the clay belt is the Hudson Bay - St. Lawrence River drainage divide which roughly coincides with the southern edge of
the Abitibi Greenstone Belt. Average overburden thickness in the clay belt typically ranges from 10 metres in the south where Lake Ojibway was shallow to 40 metres in the north where the lake was deeper. The average overburden thickness in the Golden Rule drill holes was 35.6 metres.
Relief is generally low across most of the property due to the levelling effect of Lake Ojibway sedimentation. Elevations range from a minimum of 279 metres
above sea level along the north-flowing Riviere Adam, which drains the central
swampy portion of the property, to a western maximum of 295 metres on a small
hill just northeast of Lac Joutel (Plan 1). In the eastern portion of the property a
north-south trending, 1,000 metre wide, sand and gravel ridge rises abruptly to a
maximum elevation of 325 m. This ridge is the Harricana Interlobate Moraine and formed when the retreating ice front of the last major glaciation divided into a western Matheson lobe and an eastern Chibougamau lobe (Shifts, 1984). A series of
bedrock ridges known as the Cartwright Hills lies just south of the property. These
hills attain a maximum elevation of 445 metres and some of them formed islands in
Lake Ojibway.
The type of vegetation is controlled by the degree of drainage. In the
northeast-central region of the property drainage is non-existent and the only
cover consists of moss, grasses and scattered shrubs floating on 1 to 3 metres of
saturated peat. In the central and western regions of the property, drainage is
sufficient to allow the development of stunted black spruce separated by spongy
moss. Along the flanks of the Harricana Interlobate Moraine, moderate to good
drainage has allowed the growth of a boreal forest consisting of a relatively thick
cover of jack pine reaching a maximum diameter of 15 cm.
2.5 Previous Work
Plan 1 includes a Quebec government compilation (MERQ, 1983) of previous exploration activity in the vicinity of the Douay property.
- 15 -
As a result of the thick overburden cover on the property the closest
government geological mapping surveys have been limited to the nearby Cartwright
Hills (Plan 1).
Prior to Aabarock's acquisition of the property in 1984, there is no record of
any significant mineral exploration being conducted. Subsequent to 1984, limited
magnetometer, VLF, IP and Max-Min II geophysical surveys and some geochemical
(humus) sampling for gold were conducted. Promising geophysical targets in the
southwest portion of the property were diamond drill tested in 1985 but results
were not encouraging or conclusive.
Considerable information on the regional geological setting of the property is
now becoming available as a result of the recent discovery of gold (Golden Pond)
and polymetallic (Estrades) deposits at Casa-Berardi to the west. The Quebec
Ministry of Energy and Resources has mounted a four-year geoscientific program in
the Casa-Berardi-Matagami area; their initial geological interpretation (Lacroix,
1987) is shown in Figure 2.
2.6 Project Costs
Budgeted and actual costs for the reverse circulation drilling program are
presented in Table 3.
The proposed budget figure of $106.80/metre was based on:
1. Thirty-five drill holes totalling 875 metres (average 25 metres per
hole).
2. Drilling productivity of 7 metres per operating hour.
3. An average bit life of 60 metres.
4. A total of 140 overburden samples (average 4 per hole).
5. A final report cost of $160 per hole plus $20 per sample.

Hole depth averaged 35.6 metres, 42.4 percent deeper than expected with an associated increase of 92.8 percent in the number of overburden samples per hole.
Drilling productivity was 12.7 metres per hour, an improvement of 81.4 percent while bit life averaged 179.9 metres, an improvement of 199.8 percent. As a result, project costs decreased to $61.36 per metre and, despite the increase in hole depth, sufficient funds were available to drill four extra holes.
3.0 DRILLING AND SAMPLING
3.1 Drill Hole Pattern
Drill holes in the south-central part of the property were positioned 400
metres apart along east-west traverses using a traverse separation of 500 to 700
metres. One traverse was located along the tie line at 15+OOS (Plan 1). Another traverse was positioned 500 metres to the north (10+OOS) with the holes staggered 100 metres to the east of those on the tie line.
Drill holes in the northwestern and northeastern portions of the property
were positioned 300 to 400 metres apart and 100 to 200 metres down-ice from
previously delineated magnetic-high anomalies. The occasional hole was drilled
directly into an anomaly to determine its source.
The major direction of ice flow was 170 to 180 degrees (Prest, 1968). Thus
the east-west traverse orientation is sub-perpendicular to the ice path, maximizing
the probability of intersecting a dispersion train. Staggering the holes on adjacent
traverses narrows the gap across the ice path and should further improve
exploration coverage. East-west traverses are also oblique rather than parallel to
the east-southeast bedrock trend; the oblique orientation is preferred because it
provides more stratigraphic information and ensures detection of stratigraphically-
controlled buried valleys that could influence glacial dispersion patterns.
The 500 to 700 metre traverse separation reflects the average length of
known dispersion trains from gold deposits oriented sub-perpendicular to ice
movement (Table 4), and the 400 metre hole separation reflects the average width
of these trains, which is similar to the cross-ice length of the deposits including
their anomalous alteration halos (the heavy minerals method is sensitive to very
low grade mineralization).

3.2 Drilling Equipment
Heath and Sherwood's drill rig employed an Acker MP drill head with a 3 metre feed cylinder. The drill, together with all its ancilliary equipment including air compressor, water pump and logging and sampling facilities, was unitized and enclosed on the bed of a Nodwell Model FN-160 tracked carrier for all-terrain
mobility and all-weather operation.
The rig employed an air compressor with a rated capacity of 300 c.f.m. at 160 p.s.i. and a water pimp having a capacity of 20 g.p.m. at 600 p.s.i. Water flow
was normally restricted to 4-5 g.p.m. to improve recovery of fines. The rig was
equipped with 12 volt DC fluorescent fixtures employing Cool White tubes that simulate natural sunlight for accurate sample logging. All equipment except the air compressor and Nodwell carrier was operated hydrostatically from a central diesel engine.
The rig carried twenty-two 10-foot drill rods. The holes were logged in
metres using the approximate conversion factor of 3 metres to 10 feet which resulted in the logged hole depth being 1.6 percent less than true depth.
Heath and Sherwood supported the drill rig with a Bombardier S-15 muskeg tractor equipped with a 400-gallon, exhaust-heated water tank. Road clearing was done by Aubé Construction Limited of La Sarre, Quebec using a Caterpillar D-6 wide-pad bulldozer.
3.3 Logging and Sampling
ODM collected the Douay samples in two 20 litre buckets coupled with a plastic tube. This procedure ensures a quiet settling environment thus reducing the loss of fines encountered if only one bucket is used and allowed to overflow. Most of the clay is still lost but a recent research study made by ODM (Dimock, 1985) showed that sand loss is insignificant and silt loss is reduced to 40 percent compared to 72 percent with the one-bucket system. Interestingly, fine gold is lost
- 20 -
in direct proportion to fine minerals of low specific gravity such as quartz and
feldspar because the flake shape rather than high density of fine gold is the primary factor controlling the rate of settling. Further research conducted by ODM (Kurina, 1986) on various inlet/outlet attachments on the second bucket showed an additional 33 percent of the fine material in the overflow could be
retained by utilizing a horizontally curved inlet tube for spiral flow and a vertical
stack skimmer on the outlet. The two-bucket system with the modified flow
configuration was employed on the Golden Rule program.
ODM employed a 10-mesh (1700 micron) screen over the first bucket to separate and discard the majority of rock cuttings and thereby increase the
proportion of matrix material, which is needed to identify and trace dispersion
trains. The +10 mesh rock cuttings were constantly monitored to discern any
variations that could give clues to overburden stratigraphy, or for any clasts indicative of an environment suitable for gold or base metal mineralization. Approximately 20 percent of the cuttings were kept for future reference. The degree of sorting of the -10 mesh matrix was monitored to differentiate till from
sand and gravel.
Till units were sampled continuously using an average sample interval of 1.5
metres. Glaciofluvial and related sand and gravel were sampled over longer, 3 to 6
metre intervals because they are far-travelled and thus generally ineffective for mineral tracing. Glaciolacustrine clay and silt were not sampled because they are
of no exploration value.
In the field, both the overburden and bedrock samples were assigned a number
denoting the project area (GR), the year (87), the position of the hole in the drilling sequence and the position of the sample in the drill hole. Thus a designation such as GR-87-35-03 indicates the third sample collected from the thirty-fifth hole drilled in 1987 for Golden Rule Resources.
Following collection, the overburden samples were reduced to 7-9 kilograms with an aluminum scoop, packed in heavy plastic bags and shipped in 20-litre metal pails to the ODM processing laboratories in Nepean, Ontario.
-21-
3.4 Sample Processing
ODM's processing procedures for the overburden samples are illustrated in the flow sheet of Figure 5 and may be summarized as follows:
First, a 250 gram character sample is extracted from the bulk sample using a tube-type sampler. This character sample is dried and stored for future reference.
On some programs, its minus 250 mesh fraction is separated and analyzed to allow
comparison with the heavy mineral analyses.
The remainder of the bulk sample is weighed wet and is sieved at 1700
microns (10 mesh). The +1700 micron clasts are weighed wet and the -1700 micron
matrix is processed on a shaking table to obtain a preconcentrate. The table
concentrate and all fractions obtained from it are weighed dry. The Golden Rule sample weights are listed in Appendix B.
While the samples are being tabled, special procedures developed by ODM are
used to effect the separation of gold grains from the other heavy minerals. These
grains are picked from the deck, placed under a binocular microscope, measured to
obtain an estimate of their contribution to the eventual assay of the concentrate (Table 5), and classified as delicate, irregular or abraded (Fig. 6) to determine their
approximate distance of glacial transport. Photomicrographs (35 mm slides) are taken if more than 10 gold grains are present.
Magnetite, with a specific gravity of 5.2, is the heaviest of the common
minerals and normally forms the top mineral band on the table above garnet and epidote/pyroxene. Common flake gold coarser than 125 microns separates completely from the magnetite and is readily counted. Fine gold, thick gold and
delicate gold travel with the magnetite due to size and shape effects, and only 10
to 20 percent of such grains are readily sighted on the table. Gold particles can also be obscured by pyrite which, if it is abundant, tends to cross the table in the gold path. However, a special panning technique developed by ODM can be used to
recover the hidden particles together with some copper, lead and arsenic

pathfinder minerals. Samples are normally panned if two or more gold particles are sighted on the table or if any delicate gold is seen or if the table concentrate contains more than 10 percent pyrite. The Douay table and pan gold counts are listed in Appendix C.
The table and pan concentrates and any gold grains are recombined and the concentrate is dried. A heavy liquid separation in methylene iodide (Specific Gravity 3.3) is then performed. The light fraction (S.G. less than 3.3) is stored and the heavy fraction undergoes a magnetic separation to remove drill steel and magnetite. The Douay magnetic separates were checked to ensure that they contained not more than five percent pyrrhotite.
3.5 Sample Analysis
Subsamples of the bedrock chips (Appendix E) and 3/4 splits of the non-magnetic overburden heavy mineral concentrates (Appendix F) were homogenized
by pulping in a shatter-box and were then analyzed for gold by fire assay with atomic absorption finish, for Cu and Zn by atomic absorption and for As by
colourimetry. All analytical work was done by the Ottawa laboratory of Bondar-
Clegg and Company Limited to the specifications shown in Table 6.
Gold grains are malleable and thus are difficult to homogenize with the rest
of the sample, often forming flattened "metallics" in the pulp. To alleviate this
problem and obtain representative gold assays, concentrates that were known to
contain one or more coarse gold grains (generally over 200 microns) capable of producing an anomalous assay (over 1000 ppb) were screened to 150 mesh after pulping. Separate gold determinations were then made on the -150 mesh pulp and
the +150 mesh metallics, and a weighted average assay was calculated.

4.0 BEDROCK GEOLOGY
4.1 Regional Geology
The Douay property is in the northern, Casa-Berardi - Matagami - Chibougamau section of the Archean, Abitibi Greenstone Belt. The Abitibi Belt comprises repeated komatiitic through tholeiitic to calc-alkalic cycles of lavas and volcaniclastics with coeval clastic sedimentary rocks, porphyries, layered basic-ultrabasic sills, and intrusives of potassium poor dioritic to tonalitic composition. These rocks have been complexly deformed and metamorphosed to sub-greenschist or greenschist facies and intruded by late kinematic granodiorite and monzonite plutons (Gariepy, Allègre and Lajoie, 1984).
Bedrock exposure in most of the region is less than 1 percent; thus the geology has been mainly inferred from airborne geophysical surveys. An early lithostratigraphic interpretation by Latulippe (1975) shows the Douay property on Taibi Group sedimentary and calc-alkalic volcanic rocks between Allard Group mafic volcanic rocks in the north and Gale Group mafic volcanic rocks in the south; the Cartwright hills consist of mafic volcanics and probably belong to the Gale
Group but are included in the Taibi Group. By expanding the work of Latulippe and
incorporating new geological data from recent (i.e. Casa-Berardi) gold discoveries
and airborne geophysical surveys, Lacroix (1987) has proposed two major fault
systems (east-west and northwest-southeast) of similar age (Fig. 2) and four phases of deformation. These major faults occur as wide zones of deformation rather than as single fault planes and are generally coincident with regional sedimentary-
volcanic contacts. The E-W fault system was produced during D1 deformation and includes the Grasset, Detour and Casa-Berardi Faults, the latter of which is
associated with the Golden Pond gold deposits. The NW-SE trending set, produced during D2 deformation, includes the Douay, Harricana, Bapst and Turgeon Faults
(Lacroix, 1987). The Douay Fault, hosting Inco's "Douay Gold Zone", is shown to traverse the southern portion of the Golden Rule property.
- 28 -
The D3 and D4 stages of deformation have NE-SW and NNW-SSE trends, respectively, and are responsible for the kink bands and crenulation cleavage commonly observed in the clastic and volcaniclastic sediments.
4.2 Douay Bedrock Logging Procedures
A binocular microscopic log of all bedrock samples was prepared (Appendix D) to confirm and amplify field descriptions with the objective of producing an
accurate stratigraphic map. Particular attention was paid to primary features, and the rocks were assigned genetic names such as intermediate volcanics rather than
metamorphic names such as chlorite-carbonate schist.
Reasonably accurate measurements of primary mineralogy, structure,
texture, degree of metamorphism and alteration can be made from chip samples with a binocular microscope, but inherent limitations are present. These
limitations include:
1. Inability to differentiate gray plagioclase from pale gray-brown and
gray-green pyroxene where the grain size is less than 0.1 mm as in
many volcanic rocks. This often precludes differentiation of
intermediate volcanics from mafic volcanics in the Abitibi belt as extensive areas have undergone only sub-greenschist facies metamorphism resulting in the preservation of primary pyroxene. In
greenschist facies areas where pyroxene has been largely converted to darker green amphibole and chlorite, intermediate and mafic units can be differentiated.
2. Inability to determine bedding thickness or fragment size where the
dimensions of the beds or fragments are greater than the 1 cm diameter of the coarsest drill cuttings.
3. Inability to recognize tops in bedded sections.
-29-
4. Difficulty in differentiating certain primary structures such as pillow
selvages from secondary veins and shears.
5. Necessity of inferring gross mineralogy of aphanitic samples from rock
colour and hardness.
4.3 Bedrock Lithology of the Reverse Circulation Drill Holes
Bedrock lithologies intersected on the Douay property are listed in Table 7 and their distribution is illustrated on Plan 2. The open reconnaissance-scale drill
hole pattern does not allow identification of detailed stratigraphic and structural
relationships between rock units although broad trends are evident. The MERQ
(1983) geoscientific compilation map (Plan 1) shows a synclinal axis transecting the
property diagonally on a NW-SE trend but this could not be confirmed or disproven by the present reverse circulation drilling program.
The strata, from south to north, follow the general Abitibi Belt cycle
(submarine plain volcanism followed by central complex volcanism) of mafic
volcanics (Cartwright Hills) succeeded by increasingly felsic volcanics then
volcaniclastic, clastic and chemical sediments, suggesting a vertical or steeply dipping, north-facing succession. This is confirmed in the south by strike and dip
measurements taken from outcrops forming the Cartwright Hills (MERQ, 1983;
Plan 1) and in the north from the orientation and density of magnetic contours
associated with an iron formation. Data from the 1985 diamond drill program in the southwestern portion of the property indicate that the volcanic units dip
steeply towards the south (Boraks, 1986). This apparent contradiction is probably the result of localized low-intensity folding.
The central portion of the property is believed to be transected by a north-
south trending fault. This area was not covered by the ground geophysical surveys;
the fault inference is based on observed shearing and alteration in the reverse circulation samples plus the abrupt termination of a thick metasedimentary horizon in the same vicinity. Apparent dextral movement along the fault suggests that the east block is down-thrown, assuming that the actual displacement is vertical and the strata dip north.

A fault zone previously identified in the bottom of diamond drill Holes AAD-4 and 5 probably continues east as Hole 09, which is along strike, intersected highly sheared and brecciated intermediate volcanic rock. The trend and position of this
fault suggest that it may be related to the Douay Fault proposed by Lacroix.
A shear zone identified in Hole 19 is probably a local feature as there is no
VLF response. An east-west trend is inferred from the magnetic contours and the
orientation of nearby weak EM conductors.
Regional metamorphism of upper zeolite to lower greenschist facies is
evidenced principally by the conversion of primary pyroxene to chlorite. The
chloritization of the pyroxene was accompanied by the albitization of the
plagioclase which resulted in the formation of 1 to 5 percent disseminated calcite
in some samples.
Syngenetic, finely disseminated Fe/Mg carbonate occurs in amounts of 0.5 to
20 percent primarily in the eastern portion of the property where it is associated predominantly with a metasedimentary horizon. The only occurrences of Fe/Mg
carbonate veining are in Holes 14 and 19. In the western portion of the property
disseminated Fe/Mg carbonate is locally associated with a felsic pyroclastic
horizon.
4.3.1 Intermediate Volcanics (Unit 1)
Intermediate volcanics (andesite flows) were intersected in eight holes in the
southwestern portion of the property; diamond drilling in this area intersected the same rocks (Boraks, 1986). The andesite has a highly variable magnetic susceptibility which produces a "bull's eye" pattern when contoured. The contoured
magnetic data suggest that the northern andesite contact trends west-northwest
along a relatively straight line between L56W, 14S and L85W, 12S.
The andesite is generally medium to dark gray-green with a grain size range of 0.05 to 0.2 mm. The texture is hypidiomorphic (equigranular, interlocking) to
locally porphyritic in Holes 15, 16 and 20. The phenocrysts are almost exclusively
plagioclase and range in size from 0.5 to 3.0 mm. The primary massive structure
- 32 -
is preserved only in Holes 08, 11 and 16; elsewhere the regional lower to middle
greenschist facies metamorphism has produced a well developed foliation (Holes 15
and 20) and local schistosity (Hole 10). Subsequent brecciation, alteration and shearing have obliterated any primary and regional metamorphic features from
Holes 09 and 19.
Mineralogically, the andesite contains 70 to 85 percent vitreous plagioclase, 10 to 20 percent gray-green chlorite and 1 to 2 percent visible quartz. Plagioclase phenocrysts, where present, are anhedral to subhedral, equidimensional and evenly distributed throughout the rock; groundmass plagioclase is saussuritized and grain
boundaries are indistinct. Chlorite is an alteration product of primary pyroxene
and occurs as dull, earthy flakes. Quartz occurs primarily as 0.05 to 0.1 mm, light
gray to colourless, anhedral crystals and locally as isolated phenocrysts up to 0.3 mm in diameter (Hole 16). The most common accessory minerals are leucoxene, with a maximum concentration of 3 percent in Hole 10, and ilmenite with a maximum concentration of 5 percent (Hole 11). Other accessory minerals include trace amounts of fuchsite (Hole 19) and chalcopyrite (Hole 20).
The only visually interesting mineralization associated with the andesite is in
Hole 19. This sample gave a weakly anomalous gold value of 205 ppb. It contains 10 to 15 percent very fine-grained disseminated pyrite associated with gray-white
quartz veins (15 percent). The primary features have been obliterated by 5 to 10
percent cherty silicified patches, by 15 percent pervasive Fe/Mg carbonate (dolomite?) alteration and 5 percent Fe/Mg carbonate veins, and by 2 to 3 percent
chlorite-sericite shears containing trace amounts of fuchsite. Intense limonitic and hematitic staining covers 5 percent of the sample.
4.3.2 Felsic Volcanics (Unit 2)
Felsic volcanics (rhyolite flows) were intersected in Holes 07, 17, 18 and 21 in the west-central and central portions of the property (Plan 2). Based on the magnetic response and interpolation of the drill intersections, the rhyolite appears
to form a 450 metre wide west-northwest trending horizon that is bordered to the
south by andesite (Unit 1) and to the north by felsic volcanic tuffs (Unit 3).
- 33 -
The rhyolite is generally yellowish-green to slightly pink with a grain size ranging from aphanitic to 0.05 mm. This fine grain size precludes observation of any textural features; however the rock is very hard and siliceous. Structurally, it is massive with a poorly developed foliation present in Holes 07 and 18 and local fracturing and possible shearing in Holes 17 and 21.
The aphanitic nature of the rhyolite does not allow for accurate identification of the constituent minerals. Undifferentiated quartz and feldspar constitute 80 to 90 percent of the rock. Sericite ranges up to 10 percent (Hole 17) and generally occurs as thin discontinuous ribbons that probably trace original flow bands in the viscous lava. In Hole 21, however, the sericite occurrs as very schistose bands suggesting hydrothermal deposition along shears. Accessory
minerals include a rare trace of fuchsite in the sericite bands of Hole 17 and 0.1
percent disseminated, randomly oriented tourmaline in the sericite bands of Hole 21.
Calcite veining obtains a maximum value of 10 percent in Hole 18 while Hole 17 contains the most (also 10 percent) disseminated Fe/Mg carbonate.
4.3.3 Felsic Pyrodastics (Unit 3)
Felsic pyroclastic rocks (tuff) were intersected primarily in the western part
of the property (Holes 01, 03, 05, 06 and 12), with two isolated intersections in the
east (Holes 32 and 39). The magnetic response of the felsic tuff is identical to that of the rhyolite, precluding any geophysical differentiation. Based on interpolations of the drill intersections, the western horizon is a continuous, 125 to
150 metre wide unit trending west-northwest (Plan 2). The apparent thickening of
this horizon in the vicinity of Holes 05 and 06 is probably the result of local folding. The two pyroclastic intersections in the east probably represent isolated lenses within a predominantly metasedimentary succession.
The tuff has a yellowish-green to yellowish-gray colour with a well developed foliated to schistose fabric. The maximum grain size is probably in the range of
-34-
0.1 to 0.2 mm (ash) although no lithic boundaries were discernable even in the coarser sections (Holes 01, 05, 06 and 12). Lithic fragments generally account for 70 to 80 percent of the sample and consist of aphanitic, quartzofeldspathic material. The balance of the rock is sericite and, locally, 1 to 2 percent quartz
phenocrysts up to 0.5 mm in diameter.
The finer grained tuff (0.05 mm and less; Holes 32 and 39) locally contains
coarse ash beds (Hole 32) as well as seams of soft yellow-green sericite, harder mixed quartz and feldspar and very hard exsolved sugary quartz with, on average a
ratio of 4:3:2:1.
The majority of the tuff samples contain disseminated Fe/Mg carbonate with
a maximum concentration of 15 percent (Holes 06 and 12). Only Hole 01 contains disseminated calcite (10 percent). The maximum sulphide concentration is 3
percent disseminated pyrite in Hole 39.
4.3.4 Metasediments (Unit 4)
Metasediments were intersected in four holes in the western half and in
twelve holes on the eastern half of the property (Plan 2). All of the intersections
are relatively pristine allowing for the differentiation of either graywacke (Subunit
4a) or siltstone (Subunit 4b). Graywacke predominates in the eastern half of the
property and siltstone in the western half although most intersections contain
varying proportions of both lithologies. Siltstone intersections are consistently associated with areas of high magnetic susceptibility reflecting the incorporation of chemically precipitated iron in a deep water environment. On this basis, the
high magnetic anomaly north of Holes 05 and 06 is inferred to be a siltstone horizon although it has not been drill tested. An offset in the magnetic contours
just south of Hole 02 probably reflects local folding or a possible fault structure.
The best example of graywacke was intersected in Hole 33 and consists of
sorted fine to medium sand (0.1 to 0.3 mm) beds intercalated with about 10 percent silt (less than 0.1 mm) beds. Ten percent of the sand-size grains are colourless
quartz with the balance being gray-green, aphanitic volcanic lithics. The matrix
consists of gray-green chlorite and constitutes 10 percent of the sample.
- 35 -
Siltstone is a medium to dark, gray to gray-green, schistose to locally phyllitic rock having a grain size ranging from aphanitic to less than 0.1 mm. This variation in grain size imparts a faint bedding which is generally parallel to the
schistosity. A crenulation cleavage is occasionally present, and in some crenulated samples the schistosity is at an angle of 10 to 60 degrees to the bedding plane. As
in graywacke, the matrix chlorite is a gray to gray-green but it is more abundant (75 to 85 percent versus 10 to 15 percent). Intercalated sandy graywacke beds are
present in amounts from 10 to 20 percent.
Carbonate is widespread in the graywacke and siltstone but generally occurs
at low concentrations. Calcite occurs either as small veins (Holes 13, 28, 29, 31
and 33) with a maximum concentration of 5 percent (Hole 31) or as a pervasive
alteration (Holes 02, 04, 31, 33, 34, 37 and 38) with a maximum concentration of 15 percent (Hole 34). Fe/Mg carbonate generally occurs as fine grained
disseminations (Holes 23, 27, 28, 29, 30 and 35) at concentrations of 1 to 2 percent, reaching a maximum of 5 percent in Hole 30. The preference of the Fe/Mg
carbonate alteration for the sedimentary rocks, the consistent carbonate
concentration levels and the pervasive nature of the alteration collectively suggest
a syngenetic origin with fluid movement through the relatively porous sediments
occurring during diagenesis.
All of the metasediments contain finely disseminated pyrite with a maximum concentration of 3 percent (Hole 04).
4.3.5 Iron Formation (Unit 5)
Banded iron formation was intersected only in Hole 36 which tested the
centre of a magnetic-high anomaly in the northeastern part of the property (Plan 2). The iron content of the rock is sufficient to give magnetic values 2,000 to
5,000 gammas above those for the enclosing rocks. The southern boundary of the iron formation is denoted by closely spaced linear magnetic contours; diffusion of the contours to the north indicates the unit dips in this direction. The contoured
- 36 -
magnetic data indicate that the iron formation horizon is at least 300 m wide and 750 m long, striking west-northwest.
The iron formation is of the oxide facies, containing alternating sugary bands of black magnetite, gray-white chert and white calcite. The iron-rich bands comprise 60 percent of the rock, have a minimum thickness of 0.75 mm and contain from 60 to 90 percent magnetite. The chert bands have a maximum thickness of 1.0 mm and constitute 30 percent of the sample. They locally contain one percent pyrite as fine disseminations and as thin ribbons. The calcite bands vary from 0.5 to 1.5 mm and constitute less than 10 percent of the sample.
4.3.6 Quartz-Feldspar Porphyry (Unit 6)
Quartz-feldspar porphyry was intersected in Holes 24, 25 and 26 in the south-
central portion of the property (Plan 2). The magnetic response of the porphyry is nearly identical to that of the graywacke (Sub-unit 4a) to the north as would be
expected since both lithologies have a low iron content.
The porphyry is massive with either a purple-red hematitic stain (Hole 24) or
a pale yellowish-green colour (Holes 25 and 26). Phenocrysts account for 30 to 60 percent of the rock. Plagioclase phenocrysts vary from 0.3 to 3.0 mm, are anhedral to subhedral in shape and predominate over quartz phenocrysts by a ratio of 30:1. Quartz phenocrysts are a cloudy gray-white colour and are subhedral with a grain size range of 0.2 to 0.6 mm (Hole 25). The ground mass comprises 40 to 70 percent of the porphyry and consists of aphanitic to 0.1 mm, equigranular interlocking grains of plagioclase and quartz in a ratio of 7:3.
Disseminated Fe/Mg carbonate concentrations are 20 and 12 percent in Holes 24 and 25 respectively. Calcite veining ocurrs in amounts of 5 and 2 percent in Holes 25 and 26, respectively. The calcite veins of Hole 25 contain 0.5 percent fine, disseminated cubic pyrite plus 5 percent dark purple fluorite.

4.4 Bedrock Geochemistry
All bedrock chip samples from the reverse circulation drilling program were analyzed for copper, zinc, arsenic and gold. The analytical results are summarized
in Table 8. Anomalous gold values (greater than or equal to 10 ppb) are plotted on Plan 2. Zinc and arsenic occur only in background concentrations, and the highest
copper value is 166 ppm in the intermediate volcanic intersection of Hole 11 which
contains less than 0.0.5 percent finely disseminated chalcopyrite clustered in
epidote veins.
Fifteen of the bedrock gold analyses are greater than or equal to 10 ppb and
are shown on Plan 2 in relation to contoured Fe/Mg carbonate alteration
percentages and bedrock lithologies. Three important trends are apparent:
1. Eight of the thirteen anomalies are in the eastern half of the property,
six of which are within the metasediment horizon (Unit 4).
2. Ten of the thirteen anomalies are associated with Fe/Mg carbonate
alteration, especially in the eastern half of the property.
3. The anomalies are relatively weak (10 to 205 ppb) but often occur in
adjacent drill holes and thus appear to be interrelated.
These trends suggest that the most favourable gold exploration targets are in
the east half of the property. They also suggest that some of the gold
mineralization may be syngenetic, since much of the Fe/Mg carbonate alteration with which the gold is associated appears to be syngenetic.

5.0 OVERBURDEN GEOLOGY
5.1 Quaternary History and Stratigraphy of the Abitibi Region
The Quaternary geology of the Abitibi region, as determined by ODM from thousands of drill holes and scanty literature, is summarized in Figure 7 and Table 9. Tills from three major glaciations and sediments from two interglacial periods
are present.
The oldest till was deposited by ice moving southward from Hudson Bay --possibly 1 million years ago in Kansan time -- and is enriched in clasts of Proterozoic sandstone and Paleozoic limestone. This till is so rarely preserved that it is of no significance in exploration. The next till (Lower Till) was deposited by ice moving southwestward from Nouveau Quebec in Illinoian time more than 125,000 years ago. It is preserved in many buried valleys and contains the dispersion trains from any mineralization in these valleys. The youngest till was deposited 10,000 years ago by Late Wisconsinan ice that had split into a southeast-moving Matheson/Cochrane lobe west of Val d'Or - Matagami and a southwest-
moving Chibougamau lobe east of Val d'Or - Matagami. The esker-like Harricana Moraine was deposited at the contact between the two ice lobes.
In Yarmouth and Sangamon time immediately following the Kansan and Illinoian glaciations, respectively, interglacial sediments including soil profiles and northward-transported fluvial gravels were deposited on the Kansan and Illinoian tills. The gravels consist mostly of recycled till debris, are oxidized, and often contain wood fragments.
In Early Wisconsinan time 100,000 years ago and in Late Wisconsinan time 10,000 years ago, the region was flooded by glacial Lakes Ojibway I and II respectively, and varved clay, silt and fine sand sheets up to 30 metres thick were deposited. The Ojibway I sediments coarsen upward because they were deposited from a transgressive ice sheet. They were overridden by the thick Wisconsinan ice sheet and are indurated, dry and platy whereas the Ojibway II sediments were deposited from regressive ice, fine upward and are soft. Glaciofluvial esker/delta sands and gravels were deposited by the meltwater rivers that fed both lakes.

The final glacial event in the Abitibi was a minor southeastward re-advance of the thin Cochrane ice lobe into the north part of Lake Ojibway II, depositing Cochrane Till which consists mainly of clay recycled from the soft lake bed. When the Cochrane ice melted, Lake Ojibway II drained catastrophically, exposing the Late Wisconsinan eskers which were subject to considerable erosion by wave and wind action until they became stabilized by vegetation.
5.2 Quaternary Geology of the Douay Property
During Late Wisconsinan time the Douay property was covered first by the
Matheson ice lobe and then in the northeastern portion of Lake Ojibway. Based on regionally-spaced data points, Vincent and Hardy (1979) have estimated the maximum lake level to occur at a present elevation of 360 metres above sea level. As the average surface elevation across the property is 290 metres, this implies an average water depth of 70 metres. However, an airphoto examination of the area immediately north of the Douay property (Fig. 8) indicates a water depth of only 45
metres. A prominent strandline with a 335 metre elevation occurs on the western
side of a northwest-southeast trending esker. Kettle depressions along the esker
axis and above the 335 m elevation are dry indicating a sand bottom. These depressions have retained their steep primary slopes while those below 335 m have
washed, gentle slopes and are occupied by lakes, indicating a clay bottom.
Additional evidence of a shallow glaciolacustrine environment is the presence of iceberg scours on a platform area on the southwest side of the esker. These scours are obliquely cross-cutting linear trenches which taper and shallow to the west-
northwest, indicating that the prevailing winds 10,000 years ago were from that direction as they are today.
Prest (1968) believed that the Cochrane ice lobe advanced as far south as the Douay property, implying that the esker and icebergs were associated with this
glaciation rather than Matheson glaciation; however, this is not the case. Cochrane Till is not present on the Douay property or on a property 10 km to the northwest that has been drilled by ODM. Examination of the topographic maps
- 44 -
for the area (32E/9, 10, 15 and 16) indicates the Cochrane limit to be 30 kilometres to the northwest near the junction of the Harricana and Adam Rivers. This agrees with our drill evidence from the Casa-Berardi area, which places the Cochrane limit just north of the Estrades Deposit (Fig. 2).
Conditions in Lake Ojbway I during Early Wisconsinan time 100,000 years ago were probably similar to those in Lake Ojibway II although the earlier lake must have been very shallow as the land surface had not been recently depressed 100 to 125 metres by a heavy ice load as it had during Late Wisconsinan time. Glaciolacustrine sediments deposited in Lake Ojibway I on the Douay property
apparently were too thin to be preserved or to protect any underlying pre-
Wisconsinan units from subsequent erosion as only deposits of Late Wisconsinan and Holocene age were intersected in the drilling. These units are described in detail below and are shown in section in Figures 9 to 12. The lines of section are shown on Plan 3.
5.2.1 Matheson Till (Abitibi Unit 4)
Matheson Till is the oldest unit preserved on the Douay property. It was
intersected in all drill holes except Holes 37, 38 and 39 which were drilled on the
west flank of the Harricana Moraine. Till thickness on the western part of the
property ranges from 1 to 3 metres over bedrock highs (Holes 01, 04, 15) to a
maximum of 27 metres in a bedrock depression (Hole 19; Fig. 11). In the eastern part of the property, Matheson Till is gradually supplanted by esker-like sands and
gravels of the Harricana Interlobate Moraine (Holes 29 to 36; Fig. 12) and finally is no longer present (Holes 37 to 39).
The majority of the till matrix material consists of gray to gray-beige, fine-grained, bedrock-derived sand and silt rather than recycled glaciolacustrine
sediments, reflecting the absence or very shallow depth of Lake Ojibway I in this
area. Abundant gritty grey clay matrix suggestive of recycling is generally confined to the lower 3 to 5 metres of the till section (Holes 05, 06, 08, 09, 17, 19,
21, 22, 23, 28). Erosional sheeting of pre-till sediments was observed only in Hole
22 where a 0.4 metre thick layer of presumed Ojibway I clay was intersected near the base of an 11.2 metre thick section of sandy to clay-rich till.
- 49 -
Stratification is evident in the Matheson Till and reflects meltout in Lake Ojibway II where concurrent sedimentation was occurring. The best examples of this occur in Holes 19 and 21 where sand, silt and soft pure to gritty clay beds are
found interlayered with sandy, pebbly till.
Matheson Till is in bedrock contact in all of the drill holes in which it was
intersected. This is reflected in the clast size and lithologies and makes the till very useful for heavy mineral geochemical exploration. About 20 percent of the
holes show a down-hole increase in the proportion of mafic metavolcanic and
metasedimentary clasts and/or an increase in clast size from pebbles to cobbles.
The ratio of local metavolcanic and metasedimentary clasts to distal granitic
clasts varies from 60:40 to 70:30 in the upper part of thicker till sections to 80:20
near the base.
5.2.2 Ojibway II Sediments (Abitibi Unit 5)
Late Wisconsinan sediments related to Lake Ojibway II on the Douay property include the following subunits:
5a Glaciofluvial sand and gravel of the Harricana Interlobate Moraine on
the eastern edge of the property.
5b Moraine-proximal glaciolacustrine sand.
5c Moraine-distal glaciolacustrine clay and silt.
Deposits of the Harricana Interlobate Moraine (Subunit 5a) were intersected
in only three of the eastern-most drill holes (Fig. 12). The maximum thickness of
these sediments is 33 metres in Hole 39. The moraine rests directly on bedrock.
This indicates that prior to deposition of the moraine, all basal debris that would normally have been deposited as Matheson Till was eroded; that is, the moraine is actually a large esker. The thick moraine deposits in Hole 39 comprise fine-
- 50 -
grained grey-beige sand with interbeds of coarse-grained sand, clay and pebbly sand. The thinner intersections in Holes 37 and 38 are of esker-like, pebbly to cobbly gravel with a medium- to coarse-grained sand matrix. Clast lithologies are 65 percent mafic volcanics and 35 percent granitics.
Moraine-proximal glaciolacustrine sand (Subunit 5b) is ubiquitous on the Douay property and was intersected in all reverse circulation drill holes. It overlies either the Matheson Till or the moraine gravel and sand (Holes 37 to 39 only). The average thickness of the glaciolacustrine sand is 33 metres on the eastern part of the property (Fig. 12) and 5.6 metres on the central and western parts. The sand is grey-beige to beige and very fine-grained with common grey clay interbeds. The grain size of the sand increases down-section.
Moraine-distal glaciolacustrine clay and silt (Subunit 5c) blankets the Douay property, overlies glaciolacustrine sand in all drill holes and has an average
thickness of 11 metres. The clay is grey, pure and soft. The upper 5 to 6 metres are commonly underconsolidated and in some drill holes the first 0.5 to 1.5 metres
are oxidized beige, beige-brown or dark-brown and are slightly gritty. The clay
grades downward into silt with clay interbeds, which in turn grades downward into sand (Subunit 5b).
5.2.3 Holocene Sediments (Abitibi Unit 7)
The glaciolacustrine clay on the Douay property is completely blanketed by a thin veneer of Holocene sediments that were deposited during the 8,000 years that
have elapsed since the draining of Lake Ojibway II. The sediments are all peat, with a maximum thickness of 3 metres at Hole 33.

6.0 OVERBURDEN GEOCHEMISTRY
6.1 Regional Gold and Base Metal Background and Anomaly Threshold Levels
Heavy mineral gold anomaly threshold levels and properties of significant
gold dispersion trains are detailed in Appendix G. In summary, visible gold
particles of various sizes are randomly scattered through the till and the absence or presence of one or two of these particles in a standard 8 kilogram sample may
result in an analytical background ranging from less than 10 to greater than 50,000
ppb (Table 5). Because of this great variability, which is known as the "nugget
effect", we have established an anomaly threshold level of 10 grains of visible gold.
Recognizing that some anomalies may be caused by gold occluded in sulphides or other minerals rather than by free gold grains, we also investigate any anomalies
over a second, 1,000 ppb threshold. The 1,000 ppb value is based on the observation that heavy mineral concentrates from most gold dispersion trains have a gold content similar to that of the source mineralization; thus 1,000 ppb in the till is suggestive of anomalous bedrock and values over 3,000 ppb are suggestive of ore-
grade mineralization. Significant anomalies, in addition to being caused by more
than 10 gold grains or by occluded gold, also generally display vertical stratigraphic
continuity within the host till horizon and may have an associated pathfinder
metal, particularly arsenic or copper. Delicate or irregular gold grains are also
significant as they normally indicate a proximal source. Finally, the gold grains
should be of a common size, indicating derivation from a single source.
The base metal background of a heavy mineral concentrate, and particularly
of our high-density methylene iodide concentrates, is higher than that of a raw till
sample, ranging up to several hundred ppm, because base metals tend to substitute to a significant extent for other metal ions in the structures of heavy silicate and
sulphide minerals such as pyroxene and pyrite. The established anomaly threshold level for Cu and Zn, indicating the presence of ore-type minerals such as chalcopyrite and sphalerite in the sample, is greater than 800 ppm. Because till concentrates from dispersion train samples tend to grade the same as the bedrock
source mineralization, massive sulphide deposits which typically grade 50,000 ppm
- 52 -
(5 percent) combined Cu-Zn often produce anomalies over 10,000 ppm in each
metal. The anomaly threshold level for arsenic is the same as for Cu and Zn but
only those arsenic anomalies having a gold association are significant.
Significant base metal anomalies, like significant gold anomalies, normally display vertical continuity in the host till and have a pathfinder association. In the case of copper and zinc, the presence of grains of banded massive pyrite-chalcopyrite-sphalerite mineralization in the concentrate is a favourable indicator
whereas the presence of only coarse crystalline vein-type chalcopyrite or
sphalerite is unfavourable.
6.2 Douay Heavy Mineral Gold Anomalies
Twenty-nine of the two hundred and seventy (10.7 percent) Douay heavy
mineral concentrates yielded measured and/or calculated gold assays greater than
or equal to our 1000 ppb anomaly threshold. Visible gold was observed in 79
samples (29.3 percent). The total number of grains was 182 but only one sample
met our second, 10-grain anomaly threshold. This sample, in Hole 19, is one of the
29 that assayed over 1,000 ppb. These 29 anomalies are scattered in 21 (54
percent) of the 39 drill holes. Nineteen of the anomalies are in Matheson Till and
ten are in sand and gravel sections related to the Harricana Interlobate Moraine.
In the north part of the Abitibi region, on average, 10 percent of samples that
contain only background levels of gold yield anomalous results due to:
1. The chance occurrence of one or two coarse gold grains in the
sample ("nugget effect"), or
2. The chance clustering of 10 or more fine gold grains in the sample ("cluster effect").
- 53 -
The fact that only 10.7 percent of the Douay samples are anomalous suggests that most of the anomalies represent background noise. However, 50 percent of the holes with anomalous overburden till samples also have anomalous bedrock
values and these holes are clustered over the favourably (Fe/Mg carbonate) altered
metasediments in the east half of the property; thus the overburden anomalies may
be more significant collectively than they are individually.
A systematic, three-stage screening process has been applied to each of the
anomalous samples (Table 10) with the objective of eliminating high background noise and isolating any dispersion train anomalies that may be present.
The first stage in the screening is to downgrade anomalies which have no
stratigraphic continuity, although no anomalies are eliminated on this basis alone.
An anomaly at the base of a till horizon or in a one-sample thick till horizon is automatically assumed to have stratigraphic continuity even though it generally
does not. A lack of stratigraphic continuity is displayed by a single, isolated anomalous sample within or at the top of a multi-sample till horizon or by an
anomaly in sand or gravel. A gold anomaly with no stratigraphic continuity is generally caused by a single nugget or by an erratic cluster of background gold
grains (the "cluster effect"). These nugget or cluster anomalies sometimes occur in
consecutive samples in a drill hole and occasionally they are contiguous with a gold
anomaly of another type; we refer to this as "chance" continuity and treat the
anomalies as if they had no continuity. Twenty-four of the twenty-nine Douay
anomalies have no stratigraphic continuity, including the 10 anomalies that are in sand and gravel sections.
The second stage in the screening is used for anomalous samples with
observed gold grains. The calculated (predicted) visible gold assays are compared
to the measured Bondar-Clegg assays to eliminate those anomalies in which the
1000 ppb threshold is no longer met after the contributions of one or two observed
nuggets are subtracted from the total assay. In samples with observed nuggets and little or no fine visible gold, either a good correlation of the two assays or a low measured assay indicates that essentially all of the gold in the concentrate is in the nuggets and the anomaly is a false one.

We consider the correlation between a calculated and measured assay to be "good" if the calculated assay is not more than twice as high as or fifty percent less than the measured assay; this allows for a doubling or halving of the normal thickness factor for flake gold particles used in the calculation. Fourteen of the twenty-nine Douay anomalies show good assay correlation and are in concentrates that would assay less than 1000 ppb if the contributions of one or two observed nuggets were subtracted from the total assays. In most cases the nuggets are abraded indicating long transport. Thirteen of the fourteen "good correlation" anomalies have no stratigraphic continuity and thus are twice-eliminated; the other anomaly by chance occurs in a basal till sample.
A low measured assay for a concentrate with one or more observed nuggets indicates nugget retention in the 1/4 library split of the concentrate. If no other gold is present in the concentrate, the measured assay for the 3/4 concentrate will be below the 1000 ppb anomaly threshold. Two of the twenty-nine Douay anomalies (Samples 35-11 and 38-01) are of this type. Two abraded nuggets were
observed during tabling of Sample 35-11 and one abraded nugget was observed in
Sample 38-01. Check panning of the 1/4 concentrates showed that all of these
nuggets had been retained. The Sample 38-01 anomaly has no stratigraphic
continuity and thus is twice-eliminated; the Sample 35-11 anomaly by chance occurs in a basal till sample.
The second-stage screening is very reliable because it is based on direct
observation of the gold grains. This screening has effectively eliminated 16 of the
29 Douay gold anomalies at the 100 percent confidence level. Fourteen of the
same anomalies have no stratigraphic continuity and thus were also eliminated by the first-stage screening.
The third stage in the screening applies to samples in which the measured
assays are over 1000 ppb and are too high to be accounted for by the gold grains, if
any, observed during processing. High measured assays can be caused by any one of the following:
-58-
1. A nugget that was recovered but not sighted during processing.
2. A sighted nugget for which the actual thickness is greater than the
assumed thickness (0.1-0.2 X diameter) used in the assay calculation.
3. The difference in weight between the total concentrate on which the
calculation is based and the portion of 3/4 concentrate that is assayed (applies only to samples in which a nugget is present, as fine gold would
be evenly distributed through the sample).
4. A large number of missed fine gold grains.
5. Gold occluded in pyrite or another heavy mineral.
Unsighted nuggets normally account for about 80 percent of unexpectedly high assays, the thickness and weight factors for 10-20 percent, and fine gold and
occluded gold for less than 10 percent. Only the fine gold and occluded gold
anomalies are significant.
The third-stage screening is basically an indirect method in which a
mineralogical investigation of the retained 1/4 concentrate is made, principally by
panning, to determine the probable cause of the high assay in the 3/4 concentrate.
The 3/4 concentrate itself cannot be panned as it is pulped (ground) and largely
consumed during analysis unless the analysis is by the non-destructive instrumental neutron activation (INA) method.
An absence or minimal amount of fine visible gold in the 1/4 concentrate
precludes the occurrence of fine gold in anomalous concentrations in the 3/4
analytical split, and such anomalies can be assumed to have been caused by a
missed or unusually thick nugget or by occluded gold. The potential for occluded
gold is greatest in samples that contain pathfinder minerals or more than 10 percent pyrite. Where uncertainty exists the 1/4 concentrate can be analyzed by the non-destructive INA method with the hope of duplicating the 3/4 analysis and
- 59 -
thereby proving the presence of occluded gold. The third-stage screening then becomes a direct rather than indirect method and is essentially 100 percent
reliable.
Twelve of the thirteen anomalies that could not be eliminated by the second-
stage screening gave unexpectedly high measured assays and thus are amenable to third-stage screening. Check panning of the 1/4 concentrates of these twelve
samples yielded zero to two or three grains per sample. These grains are all of the abraded background type and are so fine that no grain would contribute more than
300 ppb gold to the assay; thus the anomalies were not caused by fine visible gold.
Occluded gold can also be discounted since pyrite levels are generally less than 10
percent and often less than 4 percent, and no arsenopyrite or other pathfinder minerals are present. Thus these 12 anomalies can be inferred with a high level of
confidence to be due to erratic background nuggets that were recovered but not sighted during sample processing. Ten of the same anomalies have no stratigraphic
continuity and thus are twice eliminated; the other two by chance occur in basal till samples.
With 16 and 12 anomalous samples now eliminated with complete confidence
by the second and third-stage screenings, respectively, only Sample 19-18 has been
identified as being potentially significant.
6.2.1 Hole 19 Gold Anomaly
The anomaly in Hole 19 occurs at the base of a 22.3 metre section of
Matheson Till resting on bedrock. Thirty-one gold grains were sighted during
processing; 29 are delicate and 2 are irregular and the average diameter is between 50 and 75 microns.
The observed abundance, shape, size and position of the gold grains indicate
either glacial dispersion from a very local source or milling of gold from a cobble or bedrock by the drill bit. The underlying bedrock yielded a 205 ppb gold anomaly
and thus is the most probable source of the overburden anomaly. The most
- 60 -
conclusive piece of evidence for a bedrock source would be to observe drill bit striae on the gold grain surfaces. The small size of the gold grains in this case makes identification of striae impossible but the +10 mesh clast fraction of the till does contain 10 to 15 percent bedrock cuttings. As well, the gold grain panning
description mentions several grains with limonite in their pitted surfaces, implying preglacial oxidization and leaching of the source mineralization, and 5 percent of
the bedrock chips show similar hematite and limonite staining.
6.3 Douay Copper, Zinc and Arsenic Heavy Mineral Anomalies
The heavy mineral anomaly threshold for copper, zinc and arsenic is 800
ppm. On the Douay property, background levels for copper and zinc (40-200 and
20-150 ppm, respectively) are relatively consistent with Abitibi Belt averages while arsenic levels tend to be slightly higher (20 to 600 ppm).
None of the 270 heavy mineral concentrates are anomalous in zinc. Sample
18-04 is slightly anomalous in copper (1,060 ppm). Examination of the 1/4
concentrate identified 0.3 percent chalcopyrite grains as the mineral source but
the style and host of the mineralization could not be determined. This anomaly is
not considered significant as there is no zinc or gold association.
Samples 17-06 and 28-11 are marginally anomalous in arsenic with respective values of 1750 and 1225 ppm. Both samples are from Matheson Till at the bedrock
interface. Examination of the 1/4 concentrate splits identified arsenopyrite as the
mineral source with respective concentrations of 0.4 and 0.3 percent. The arsenopyrite occurs as coarse (250 to 500 micron) grains suggesting a vein-type
source. Neither anomaly is considered significant as there is no gold association.
All seven till samples from Hole 23 returned elevated but sub-anomalous
(generally 200-500 ppm) values of copper, zinc and arsenic. The 1/4 concentrates contain traces of chalcopyrite, sphalerite and arsenopyrite and 45 to 60 percent pyrite. Ninety percent of the pyrite occurs as coarse cubic grains while ten
- 61 -
percent occurs as fine disseminations within quartz-carbonate rock chips
suggesting vein-type mineralization.
7.0 CONCLUSIONS AND RECOMMENDATIONS
7.1 Gold Potential of the Douay Property
The Douay reverse circulation drilling has shown that the property has a
geological environment that could host significant gold deposits. Golden Rule's
assumption that the property is along strike from Inco's Douay Gold Zone appears
to be correct as the stratigraphic patterns are very similar in both areas and the
Douay Fault that is said to control the Inco mineralization appears to pass through
the southern Golden Rule claims.
The south-central and eastern areas of the property have the highest gold
potential. In the south-central area, weak gold mineralization (Hole 19) occurs in a
silicified and Fe/Mg carbonate-veined, east-west trending shear zone in
intermediate volcanic rocks in close proximity to a quartz-feldspar porphyry intrusion. Pyrite and Fe/Mg carbonate enrichment, traces of fuchsite along some
shear surfaces and the nearby occurrence of fluorite (Hole 25) attest to the movement of hydrothermal fluids.
In the eastern area, gold enrichment occurs in several adjacent holes and
appears to be related to disseminated Fe/Mg carbonate alteration of probable
syngenetic origin in the thick graywacke/siltstone sequence rather than to hydrothermal Fe/Mg carbonate veining.
The gold content of the till is relatively low but, considering the wide hole
spacing, is not particularly detrimental to the overall gold potential of the property. Indeed, a high background is generally a nuisance as it is caused by the cluster and nugget effects. Most of the overburden gold anomalies on the property
are nugget anomalies but these anomalies may collectively be significant as they
are clustered in the east where the bedrock alteration and gold geochemistry are the most favourable.
- 62 -
7.2 Recommended Follow-Up
The gold mineralization on the Douay property is restricted to the eastern half and all future exploration efforts should be restricted to the area bounded by
lines 30W to 60W.
The first priority is to establish grid lines at the west end of the target area,
which was not covered in Golden Rule's earlier geophysical surveys, and to extend all grid lines between lines 40W and 60W to the southern property boundary.
Magnetometer and VLF geophysical surveys should then be performed on these lines and tied in to the earlier surveys.
The gold mineralization intersected in Hole 19 should be further assessed
with fourteen reverse circulation drill holes using a 100 x 100 metre pattern as shown in Plan 4. The initial reconnaissance reverse circulation drill coverage
should also be enhanced with twenty fill-in holes as shown in Plan 4. Assuming an average hole depth of 40 metres for the 34 proposed reverse circulation drill holes
and an average all-inclusive cost of $65/metre, the cost of the follow-up drilling would be $88,400.

1. Regional Gold Background
Most gold occurrences in the Abitibi belt are of the free gold type. Even in Casa-Berardi or Hemlo-type deposits having a high pyrite/arsenopyrite content,
most of the gold is free although very fine grained (50 microns). Thus, all tills over the Abitibi belt contain scattered free gold particles. Due to the nugget
effect — the chance occurrence of a coarse gold particle in a given sample -- the gold backgrounds of small till samples collected at the same site will vary by
several orders of magnitude.
The nugget effect can be overcome if a sample of sufficient size is collected
and all of the gold is concentrated into a small heavy mineral fraction that is then
analyzed in its entirety (Clifton et. al., 1967). We have found that at least 50 kg of
till would be needed to overcome the nugget effect. However, it is impractical to
collect, process or analyze samples of this size. We have standardized to 7-9 kg samples because reverse circulation drills deliver this quantity of material during one metre of advance.
Rather than trying to eliminate the nugget effect, we have developed procedures for recognizing and discounting anomalies that are caused by it.
Specifically we measure the dimensions of all gold grains sighted on the table or
recovered by panning and use these dimensions to calculate the expected
contribution of each gold grain to the concentrate assay. In this way, the cause of
each high assay is identified and nugget anomalies are screened out.
Most gold particles occur as thin flakes and it is difficult to position these flakes on edge to measure their thickness. However, we have found that each flake
can be treated as a disc in which the thickness is a function of the diameter. For flakes of less than 1000 microns diameter, this relationship is expressed by the following equation:
t = 0.2d - 0.01(d-100) d 100
-2
Thus, by simply measuring the diameters of the gold flakes that separate from the
samples during tabling, it is possible to calculate the relative volume of gold in a
given flake and from this relative volume to calculate the geochemical assay that
the flake would .produce in a sample of specific size. Clifton (1967) showed that a
100-micron flake will produce a value of approximately 100 ppb in a 15-gram
sample. Conveniently, the analyzed 3/4 concentrates of reverse circulation
samples also weigh about 15 grams. The range of assays produced in a concentrate
of this size by a single gold flake of varying size is shown in Table 5.
It is apparent from the figures in Table 4 that till concentrates that contain
no free gold will assay less than 10 ppb provided occluded gold is also absent.
Concentrates containing a single gold particle will assay from 10 ppb to more than
55,000 ppb depending on the size of the gold particle. Thus the normal background for till concentrates ranges from less than 10 ppb to more than 55,000 ppb.
We have found that fewer than 30 percent of till concentrates from the
Abitibi region yield gold assays lower than 10 ppb. Most samples give assays of 20
to 500 ppb, because they contain one to five gold particles in the 25 to 150 micron
range. Erratic clustering of these fine grains occasionally results in an assay over
1000 ppb. Another five to fifteen percent of samples contain a coarser gold grain
that produces an assay over 1000 ppb. Occluded gold is rarely present.
2. Gold and Base Metal Anomaly Threshold Levels
Gray (1983) observed that heavy mineral gold assays in a number of dispersion
trains tested by Asarco were 3000 ppb or higher. We have arrived at the same 3000
ppb threshold figure in a different manner. As early as 1976, we recognized that
the grade of our concentrates within 1 km of source on base metal and uranium
dispersion trains was similar to the grade of the source provided the source was of
normal width (5 to 10 metres) and was oriented perpendicular to the direction of
glacial ice advance. We have since proved that the same relationship applies to gold dispersion trains. Thus, assuming that gold mineralization must grade a
-3
minimum of 3 g/tonne (3000 ppb) to be significant, the anomaly threshold level in
our concentrates is 3000 ppb.
It is not uncommon for gold deposits in the Abitibi belt to have a subcropping
strike length of only 100 metres. Most of these deposits strike sub-parallel to
bedrock stratigraphy and sub-perpendicular to glaciation. Using the 3000 ppb
anomaly threshold level, a cross-ice reverse circulation drill hole separation of 100
metres would be needed to detect the deposits. However, most of the deposits
occur in anomalous horizons that are much larger than the deposits themselves. If
a low anomaly threshold is used and careful gold grain counts are made, the
anomalous horizons can be detected with confidence using a 300-400 metre hole
separation. This greatly reduces. exploration costs. We therefore consider any gold
values over 1000 ppb to be potentially anomalous.
3. Stratigraphic Properties of a Dispersion Train
Glacial processes are systematic and heavy mineral dispersion trains in tills
have specific configurations (Averill, 1978). For example, dispersed material tends
to be sheeted progressively upward in the ice with increasing distance from source,
causing the trains to rise in the till and thicken down-ice. Lateral spreading, in
contrast, is minimal and most trains are tapered ribbons rather than fans.
ODM has traced nine. gold dispersion trains (Table 4) and several base metal
and uranium trains to source on both new discoveries and known deposits. These
trains have had the following properties:
1. At a specific distance from source, the mineralization was confined to
a specific level within a specific till unit.
2. The train was at least two samples (2-3 m) thick unless:
(a) The host till was very thin;
or (b) The train was intersected within 100 m of source.
-4
3. The width of the train was not more than twice the cross-ice length of
the source mineralization.
4. The maximum length of the train for deposits oriented perpendicular to
glaciation was 1 km (gold) to 5 km (base metals/uranium).
4. Properties of a Visible Gold Dispersion Train
Five to fifteen percent of background till samples over the Abitibi belt
produce heavy mineral gold anomalies higher than our 1000 ppb threshold due to
the nugget effect. For the reverse circulation/heavy mineral method to be
effective, significant free gold dispersion trains, which are relatively rare, must be differentiated with confidence from the numerous nugget anomalies. This is done
on the basis of the gold grain counts rather than the assays. We have found that
the gold particles in significant dispersion trains have the following properties:
1. At least 10 gold particles are present per 7 kg of till matrix.
2. The gold particles are of a common size, reflecting the size of
crystallization at source.
3. The gold particles are of a common shape, reflecting a common
distance of transport from source.
4. Since most gold dispersion trains are traceable for less than one km
(Table 4) and gold particles become abraded after one km of ice
transport (Fig. 6), the shape of the gold particles is usually irregular or
delicate. We have never been able to trace an abraded gold anomaly to
a bedrock source.
Background nugget anomalies, unlike dispersion trains, do not normally repeat
vertically or horizontally in the section, although with 10 to 15 percent of samples
containing anomalies of this type, chance repetition does occur. Another property
common to some gold dispersion trains is the presence of pathfinder minerals
-5
because many gold deposits are polymetallic. Even deposits that are considered to be strictly free gold occurrences often have alteration halos containing sufficient
pyrite, arsenopyrite, galena, chalcopyrite or molybdenite for a pathfinder
association to be evident in the dispersion train. Nugget anomalies have no
pathfinder association.
5. Properties of an Occluded Gold Dispersion Train
We have encountered only one occluded gold dispersion train among nine gold
trains tested. In one other train, the gold was very fine and more was recovered as
composite gold/sulphide grains than as free grains.
In occluded gold trains it is not possible to use gold particle shape to predict distance to source. The distance must be gauged from the vertical positions of the
anomaly in the host till and of the till in the stratigraphic succession. In several
other respects, however, occluded gold dispersion trains are easier to trace than
free gold dispersion trains, especially if the gold is occluded in sulphide minerals. The following specific advantages are cited:
1. A pathfinder mineral association is generally present.
2. The pathfinder minerals often occur in sufficient concentrations that
they can be seen in pebbles as well as in the heavy mineral fraction, and the host rock can therefore be determined.
3. The source mineralization is often conductive and can be located by geophysical methods.
4. Gold/pathfinder metal ratios in the concentrates are relatively
constant, and any interference from background nuggets is readily recognized.
5. The dispersion trains are longer and more uniform than free gold trains.
6
Some of these advantages apply only to unoxidized till samples from drill
holes. Occluded gold is chemically reconstituted into the clay fraction if the host
sulphides are destroyed by oxidation. Thus, in surface pit sampling programs, heavy mineral analysis will detect only the visible gold. Conventional geochemical analysis should be used if occluded gold targets are expected.
