3.3 Details of Alternate Sites
No alternate site was considered as the project is mineral specific and site specific.
3.4 Size or magnitude of operation
The proposed mine has lease over an area of 2.33ha. andthe production rate of Quartz is
312 Tonnes/Annum, Feldspar is 1560 Tonnes/Annum & Mica is 250 Tonnes/Annum. The
lease follows Underground manual mining.
3.5 Geology and Reserves
3.5.1 Topography
The mining lease area is part of Nellore Mica Belt (NMB). The NMB area is plain except for
some mounds or hillocks consisting of resisting rocks. The average elevation of land is 50 Mt
above Mean Sea Level. The rain water is drained through seasonal nallahs / gullies into
Pennar River which empties in Bay of Bengal. Some low lying land areas are storing water
and the water is used for agriculture. Some artificial ponds are constructed to store rain
water for use in agriculture. The mining lease area is having maximum relief of 3 Mt from
NW to SE. There is one open excavation measuring 20 / 30 Mt on surface and an
underground mines opening from the bottom of the open excavation. There is no cultivated
land in the mining lease area.
3.5.2 Geology
The Nellore Mica belt is about 110 Km long from Vinjamoor in the North to Ozili in the South.
The width of Mica belt varies from 10 Km to 30 Km. The Nellore Mica belt is located between
14o to 15o North Latitudes and 79o 35” to 80o Eastern Longitudes. The depth of Pegmatite
varies from 10 to 350 M. The dips of Pegmatite lances are 45o to 80o towards West. This
Nellore Mica belt is divided into 6 zones as detailed below.

PROJECT: M/s. Nellore Mica Mine Association PRE-FEASIBILITY __________________________________________________________________________________________
PFR-VIII
The mining lease area is in the 3rd zone, namely Podalakur – Talupur. The granites and
pegmatite have intruded into schists of KandraVolcanics, which contain Quartz, Biotite and
Hornblende Schists. Under favourable conditions, Muscovite books of commercial grades
have formed by intrusion of pegmatite into schists. Hundreds of Mica Mines were worked in
the Nellore Mica belt. The available information is Rubby Mica was found in 4th & 5th zones
and green mica was found in other zones.
REGIONAL STRUCTURAL FEATURES
The trend of rocks is NNW to SSE. Extensive disturbances took place due to repeated
intrusions of pegmatite and granite. This resulted in faults and metamorphism of strata mica
books formed were disturbed and parallel or en-echelon pattern of pegmatite lenses were
formed. Presently some of the pegmatite lenses are hidden below surface. Soil cover of 1 to
3 Mt thick is present.
LOCAL GEOLOGY
A pegmatite lense is outcropping in the mining lease area. The dimention of the pegmatite
on surface is 25 Mt wide and 50 Mt long. The country rocks is hornblende – biotite schist.
This was worked earlier upto a dearth of 48 Mt. Three levels at 30 Mt, 40 Mt and 48 Mt depth
were excavated. The pegmatite lense shows a slight north plunge at 48 Mt depth. The dip of
pegmatite is 60o towards west. The strike of pegmatite is NNW to SSE. There are adjacent
mines working under the same management.
3.5.3 Exploration
As per the exploratory mining done, the lessee has proved the pegmatite upto a depth of 70
Mts and the width of the micaceous pegmatite varied from level to level. The micaceous
pegmatite delineated 3 dimensionally by means of exploratory mining is considered as G2 in
accordance with UNFC if explored within an interval of 10 – 48 Mts and is considered as G2
if exploration is done at an interval of 48 – 78 Mts. The mineral in the top cover of
underground excavation is considered exploratory mining zone.
The detailed exploration including geological survey, geophysical probing and underground
workings at 10 mt depth interval, complete meter wise chemical analysis and study of data
has indicated recoverable / saleable Feldspar, Quartz & Mica reserves of 89,687.50 Tons
and Pegmatite can be economically extracted upto 222 mt RL. The grade is also increasing
with depth.

3.5.4Reserves
Upto 48 M level, even though 48 M depth is proved, for the purpose of calculating
geological reserves, 48 M is considered, because pegmatite was already was
excavated. 48 M of insitu pegmatite is considered for calculation, allowing for old
excavation. The volume is 35,875.00 M3 The volume of pegmatite established by
existing workings is taken as geological reserves. The minerals are calculated basing
on the experience gained in workings of adjoining mines, taking a conservative
estimate to safeguard against local variations. The pegmatite upto 48 M is taken as
Proved Reserves.
Estimation of Minerals
Probable Geological Resources of Pegmatite is 35,875.00 M3. Taking 2.5 as Bulk
Density the Proved Reserve is 35,875.00 M3 x 2.5 = 89,687.50 MT.
Mica
The content of Mica in the pegmatite is taken as 8%. Total quantity of pegmatite is
89,687.50 MT Mica content is 8% = 7,175 MT
Feldspar
Basing on the experience of adjoining mines the contents of marketable feldspar is
taken as 50% of pegmatite. The feldspar content is 89,687.50 MT x 50 / 100 =
44,843.75 MT
Quartz
The content of marketable quartz is 10% of pegmatite 89,687.50 x 10 / 100 = 8,968.75

3.9.1 Water Requirement
Water is required only for drinking purposes and dust suppression. The number of
working people is around 42 so the total water requirement will be around 500 KLD.
About 200.0KLD will be required for dust suppression and greenbelt. This water will
be supplied from bore wells of nearby area.
3.10 Quantity of Wastes to be Generated (Liquid and Solid) And Scheme for their
Management/ Disposal
3.10.1 Solid Waste Generation& its Disposal
The material will be hoisted to surface. The material will be spread on the dump. The
marketable Feldspar & Quartz will be picked up manually and the rest of the material
will be leveled on the dump yard. The marketable feldspar and quartz will be taken by
head loads to the respective stock yards. The total waste estimated per annum to be
generated will be approximately 32% of pegmatite excavation, 3,031.9 MT of
pegmatite is estimated to be excavated during first five years. 32% of this is 970.2
MT. The 4,042.56 MT of total waste rock will be spread on 2,000 Sq. Meters. Thus
the additional height of dump will be 1.5 M. The existing height of old dump is 1.5 M.
The ultimate dump height will become 3 M from surface. Pack walls will be
constructed on the periphery of dump yard to prevent wash off of dump material. The
slopes and top will be seeded with grass to suppress air born dust.
