INDIA HAS A LONG HERITAGE IN MINING.
The tell - tale evidences left includes:
the old workings,
the slag heaps,
the retorts used for smelting etc.
World w as introduced to the splendour of
diamond by I ndia in 400BC.
I ndia the sole supplier to the w orld till
discovery of Brazilian( 1728) and South
African diamond field( 1870) .
Ancient mining areas are confined to the
Proterozoic conglomerates and younger
alluvial gravel beds.
Majhgaw an pipe in Panna, MP is only
diamond mine.
Recent exploration has located 80 kimberlite
pipes of w hich 22 are diamondiferous.
India is known for its world famous diamonds since
historical times.
The celebrated diamonds of India are :
Great Moghul (787.5/289+9/16 ct),
the Koh-i-noor, (180 ?/108.93)-Jewel of British Crown
Pitt/ Regent (410/141 ct), Lover s Museum, Paris
Nizam (440 ct),
Hope, blue diamond (112/67 ct), Smithsonian Inst,
Washington
Orloff(300 ?/189.62 ct),: Kremlin Museum, Moscow
Daryia-i- noor(185 ct), Iranian Crown Jewel, Tehran
Sha : (95/88.7 cts) : Kremlin, Moscow
Great Table (250?/Not known) : Iran
The celebrated diamonds known to
have been recovered from the mines
along the alluvial tracts of Krishna
River, perhaps aptly referred to as
Diamond River by Ptolemy.

GOLD
I ndia has gold mining antiquity and w as a leading
producer from 1897-1937.
Kolar gold field has produced + 800tones of gold.
Current production of gold comes from the Achaean
Greenstone belts of Karnataka and Jharkhand.
Geological prospectivity exists in :
Achaean Granite-greenstone terrain
Proterozoic fold belt/ Supracrustal belt
Granulite terrain in South I ndia
Laterite and Placer gold
Recent finds:
Dona, Achaean Greenstone Terrain,AP : 19 tonnes
Bhukia ,Proterozoic fold belt of Rajasthan: 94 tonnes
Parasi, Proterozoic fold belt of Jharkhand: 4tonnes
India
India is the biggest consumer of gold.
Annual consumption (855 tonnes)
outweighs production (~8Tonnes)
Huge scope for exploration and
exploitation with a ready available
market
BASEMETAL
Presence of old workings still
Indian subcontinent has ancient considered a strong positive clue for
history of base metal (copper) base metal prospecting.
mining and smelting dating back Major basemetal deposits being
to Harappan and Mahenjodaro exploited includes: Khetri (133x1.3),
civilization (2000-2300 B.C.) Malanjkhand(236x1.28), Rampura
Agucha(61x12-13), Sindheswar
(324x4-7), etc
Geological environment and Geographical extent:
Hosted mainly in late-Archaean to early Proterozoic supracrustal belts
and granitoids.

I NDI A EXPLORATI ON & MI NI NG MI SSI ON
I ndia comfortably placed in resource position
and exploitability in several mineral
commodities but is import dependent on quite
a few minerals.
To fulfill the rising demands efforts to
augment the resource base through induction
of modern technology and adequate fund flow
is essential.
To convert the needs into reality, significant
changes in the National Mineral Policy have
been proposed to the Government for
consideration.
INDIA EXPLORATION & MINING MISSION
STRENGTH :
High geological potential & reliable
geo-scientific database.
_ Ancient mining activity.
Rapidly developing infrastructure.
Large technical manpower availability.
Political stability & rule of law.
Organized banking system &
dynamic financial institutions.
Investor friendly Govt. policy and new
policy initiatives.
Weakness
World class deposits exist and are being
exploited. Available identified prospects are
small and medium sized and have been
prospected up to a shallow depth.
Resources are much more than reserve.
Resources have to be converted to reserve.
Inadequate availability of venture capital,
developing infrastructure, obsolete
technology resulted in low productivity.
Opportunity
Large area reconnaissance permit including aerial survey.
Exploration and exploitation of thirteen minerals
Conversion of resource to reserve for small and medium
sized deposits. Deeper probing to augment reserve.
Modern technology for discovery of concealed deposit and
conceptual oriented exploration in known metallogenic
provinces and virgin areas..
India continues to be a net importer of minerals and
metals.
INDIA EXPLORATION & MINING MISSION
Opportunities for fresh investment
Development and augmentation of production of surplus
commodities like iron ore, bauxite, coal, beach placers etc.
Development of known deposits of economic and marginal
deposits of economic and marginal categories awaiting
exploitation such as basemetal deposits of Bihar,
Rajasthan and some other sectors
Cluster mining of small deposits of gold , tungsten,
basemetals etc.
Concept oriented regional scanning in known metallogenic
provinces and virgin areas for locating additional resources of
gold, diamond, basemetal, tungsten, tin , molybdenum etc.
INDIA EXPLORATION & MINING MISSION
Opportunities for fresh investment
Search for mineral commodities which are yet to be located (except
in few places): such as PGE, Ni- sulphide, some rare earths and
rare metals in conducive metallogenic provinces.
Development of placer gold resource located along the frontal belt of
Himalaya and other selected sectors of Peninsular India.
Exploitation of lateritic nickel in Orissa, molybdenum in Tamil Nadu,
Scheelite resource located in various parts of the country and gem
stones.
Augmentation of recoverable resources of chromite and
manganese.
Development of offshore placers and coal bed methane.
Threat
Uncertainty in the field of mineral
exploration and the success rate
. Here shall he see no enemy
but winter and rough weather .
16% of the world population inhabiting 2.4% of land area
will require natural resources for sustainable development.
Shortage of resources of many critical minerals
Low per capita consumption today: accelerated growth
likely to trigger off tremendous demand for mineral
resources including water.
Conducive environment being created through liberalized
mineral policy.
The explorers and miners of this millennium will have to
search for natural resources for tangible solutions for the
mutual benefits
Technical and scientific manpower available
on mutually agreed terms in all the fields of
exploration and exploitation from GSI, IBM,
MECL.
Field visits can be organized as a package
deal.
Prospect based geochemical maps available.
Regional geochemical maps are being
generated through Regional geochemical
mapping.
Geological map : Quadrangle sheet
(1:250,000):India covered by 394 sheets , 282
already available in printed form.
Geological map : 1:50,000; India covered by 5014
sheets : 4176 sheets have been compiled and
available.
Library facility, having a data base of over 155
years is accessible for published material and for
unpublished material (reading only).
In addition district resource maps and mineral belt
maps are also available.
Analytical facilities with instruments like ICP-MS,
ICP-AES, XRF, GF-AAS etc can be availed.
Derivative maps produced by aero
geophysical survey and remote sensing can
be available on customized demand.
General Information Dossier (GID) giving
general picture of the mineral potential of
various geological domains/milieu available
for : Gold, Diamond, Bauxite, Iron ores,
Manganese, Molybdenum, Chromite,
Tungsten and Copper-lead-zinc.
Basic data on mineral provinces, belts and
known deposits and occurrences available in the
form of detailed information dossier (DID): on
Gold, Diamond, Bauxite, Iron ores, Manganese,
Molybdenum, Chromite, Tungsten and Copper-
lead-zinc.
DID gives an idea about the potentiality of each
block explored so that prospective investors can
apply for PL/ML and obtain GSI regional
exploration report carried out in various stages
(P-I,P-II, E-I & E-II) and MECL detailed exploration
report, after getting the mineral concessions.
