G-3 stage investigation by detailed
mapping has been carr ied out to
delineate southern extension of the
mineralised zone. The current map-
ping and detailed surface geochemi-
cal evaluat ion not only helped in
tracing the southern extension of
the main mineralised zone exposed
in Nanagwas main block but also
helped in delineating an additional
mineralised zone in the eastern part
of the block for a strike length of
about 1550 m. The drill ing in the
western zone established strike con-
tinuation up to 800 m. Similarly,
four boreholes drilled in the newly
delineated eastern zone established
subsur face con t inua t ion o f
mineralisation at least for 800 m,
though surface extension has been
establ ished for a s t r ike length of

G-4 stage preliminary search for potash
in gluconite sandstone/shale has been
carried out by mapping. As part of
surface exploration, 403 bedrock
samples were collected, including 80
pitting/trenching samples. A total
length of 300 m has been drilled in
scout boreholes. A total of 255 core
samples were processed for chemical
analysis. 37 rock samples representing
different litho units in the area were
collected for petrographic study. A total
of 5 rock/mineral samples were also
collected and submitted for XRD
analysis. The detached band of
glauconitic sandstone is recorded near
Mahuali. It varies in thickness from
1 m to 2 m and exends over a strike
length of 2 km. The olive-green Panna
shale is glauconitic in nature. The
maximum content of K2O in olive green
shale is 5.65% near Bapoti and 4.95%
near Kanotipura village. The maximum
value of K2O analysed in Taragarh
sandstone is 3%. The youngest
formation in the study area is Maihar
Sandstone, very limited exposures
intercalated with glauconitic sandstone;
lie in NE part of the study area near
Mahauli, Kharsai, Rajor and Atwewa
areas. The thickness of glauconitic
level varies from 0.01 m to 1m.
Petrological study indicates that
glauconite mineralisation in Panna
Shale and Jhiri Shale is of disseminated
type and is very fine in nature. In
sandstone of Taragarh and Maihar
formation glauconite mineralisation is
in the form of thin lenses and is
coarse in nature. The analytical result
of 33 bedrock samples indicates that

recorded in 6 samples from granite
exposed near Miyasa, Murasel and Goj
areas. Analysis of pyrite- bearing grey
quartzite to the west of Dolipada
recorded Zn content of about 784 ppm.
Analysis of two channel samples and
five grab samples collected from a 500

exposed near Dolipada village recorded
zinc and lead, whose concentration
range from 210 ppm to 0.75% and 100

G-3 stage investigation for gold and
associated basemetal mineralisation
was carried out. Exploration of gold-
copper mineralisation by drilling in
Mahuri Khera area was taken up based
on encouraging gold and copper values
in channel samples collected from the
area during 2014-15. During 2015-16,
four boreholes were drilled to test the
depth continuity of 800 m long
mineralised zone (MZ-I). Surface
evidences of mineralisation are in the
form of gossan, ferruginisation,
silicification, wall-rock alteration, old
workings and malachite/azurite
staining. Indication of mineralisation
is also seen in the form of intense
sil icif ication and hydrothermal
alteration. Fresh sulphides in the form
of pyrite and chalcopyrite are recorded
in dolomitic marble and tourmaline
bands. Based on these surface
indications, seven mineralised zones
have been identified. The sulphide
zones (1.10 m to 9 m) are recorded
mainly in the altered dolomitic marble
and massive dolomitic marble with
sparsely spaced alteration veins. The
main sulphide minerals are pyrite,
pyrrhoti te, chalcopyrite and
arsenopyrite in decreasing order of
abundance. The sulphide minerals are,
in general, medium to fine grained and
occurs as fine dissemination, veins,
veinlets, str ingers and smears.
Analytical results of core samples
received so far have revealed the
presence of 4.25m thickness zone with

G-4 stage investigation has beencarried out by scoat dri l l ing in
charanwala north area for search ofl ignite. Sixteen boreholes of
cumulative length 4,138.00 m havebeen drilled. Lignite seams have been
intersected in the central and western
parts of the area. Thickness ofindividual lignite seams varied from
0.10 m to 3.50 m in the depth rangeof 109.90 m to 196.30 m. The lignite
seam is hosted within the Lower
Tertiary Palana Formation.
G-2 level exploration was carried out
in the area during the year 2015-16.The area covers north western part
of Jaisalmer basin which comprises athick pile of sediments ranging from
continental deposit of Lathi forma-
tion of lower Jurassic age (Lias) toShumar Formation of Quaternary age
with intervening sequence of Meso-zoic-Tertiary rocks. The area in gen-
eral is structurally undisturbed withmostly subhorizontal to horizontal
beds.Tertiary limestone, popularly
known as Khuiala Limestone occursin the form of a sickle shaped expo-
sure covering more than 900 sq.km.area. It has been assessed largely as
chemical /SMS grade. About 60% areais covered by the recent alluvium or
blown sand. The fragmentary iron-
stone belonging to Shumar formationof Quaternary age is developed in
the north eastern part of the area.Marl, calcrete/pebbles spread is also
observed in the area. Small exposures
of light pink to pinkish white, hardand massive nodular limestone were
recorded in the southern part of thearea. All the 50 boreholes have in-
tersected both hard and compactlimestone which is expected to be of
SMS grade and impure l imestone
which is expected to be of cementgrade. Hard and compact limestone
has been encountered in the form ofbands in the impure limestone, whose
thickness varies from 1 m to 16 m
along borehole. Thin bands ofgypseous clay have been recorded in
the boreholes located in the north-ern parts of the area. After receiv-

Detailed mapping at G-3 level
exploration has been carried out
during the year 2015-16. The area
forms flat topography with isolated
exposures of bioclastic l imestone,
clayey foraminiferal limestone, fullers
earth and ironstone fragments. Iron-
stone fragments are mainly present on
top of foraminiferal limestone as cap-
ping and as pebble spread at other
places. The beds are horizontal to sub-
horizontal. Selenite variety of gyp-
sum is also observed at few places on
the surface as well as in borehole in-
tersection. Visually it is interpreted
that about 20% of limestone inter-
sected will be SMS (LD) grade. 1 to 2
bands of hard and compact limestone
and impure clayey l imestone and
chalky l imestone have been
intersected in different boreholes.
Thickness of l imestone band
intersected in different boreholes
varies from 25 m to 40 m and

Production
The total estimated value of mineral production
(excludes atomic mineral) in Rajasthan during
2015-16 at A 34,384 crore increased marginally by
1% as compared to the previous year. The State
contributed about 12% in the total value of mineral
production in the country in 2015-16. Of the total
estimated value 45% pertains to petroleum (crude)
alone. Production of different type of of minerals
(excluding minor minerals) have been reported from
the State of Rajasthan. It was the sole producer of
lead and zinc ores and concentrates, selenite and
wollastonite. Almost entire production of silver in
the country was also reported from the State of
Rajasthan during 2015-16. It was also the leading
producer of phosphorite/rock phosphate account-
ing 96% and limestone 22% of the total production
in the country. Besides, it was the second leading
producer of copper concentrates contributing 45%,
copper ore 28% and petroleum (crude) 23% of the
nation’s output for the year 2015-16.
The State Rajasthan claims the top position
among all the States in the country and accounted
about 12% of the total value of mineral production.
Among the important minerals, production of copper
concentrates increased by 45%, lead concentrates
32%, silver 30%, copper ore 17%, natural gas
(utilised) 14% and limestone 8% as compared to the
previous year. However, decrease in production was
noticed in zinc concentrate (1%), iron ore (3%),
petroleum (crude) (4%), wollastonite (6%),
phosphorite/rock phosphate (8%), lignite (12%),
manganese ore (56%) and vermiculite (77%) as com-
pared to that in the previous year. (Table-4).
The value of production of minor minerals was
estimated at A 8,807 crore for the year 2015-16.
The number of reporting mines in Rajasthan was
only 76 in the year 2015-16 as against 545 in
previous year.
