The Geological Survey of India has taken up seven projects in 2021-22 for exploration of lithium reserves in various states of the country, the government told the Parliament on Wednesday (28 July).
Lithium, a strategically important metal, is a key element for new technologies and finds its use in battery, ceramics, glass, telecommunication and aerospace industries. The well-known uses of Lithium are in Lithium ion batteries, lubricating grease, high energy additive to rocket propellants, optical modulators for mobile phones and as convertor to tritium used as a raw material for thermonuclear reactions i.e. fusion.
In a written reply to a question in Lok Sabha, Union Minister of State for Mines Prahlad Patel said, “During Field Season Programme (FSP) 2016-17 to FSP 2020-21, GSI carried out 14 projects on Lithium and associated elements in Bihar, Chhattisgarh, Himachal Pradesh, Jammu & Kashmir, Jharkhand, Madhya Pradesh, Meghalaya, Karnataka and Rajasthan”.
“During the present FSP 2021-22, GSI has taken up 7 projects on Lithium in Arunachal Pradesh, Andhra Pradesh, Chhattisgarh, Jharkhand, Jammu & Kashmir and Rajasthan,” he said.
The minister, however, the added that resource of lithium has not yet been augmented by GSI, a Ministry of Mines release said.
Every year, as per approved annual Field Season Programme [FSP], GSI takes up different stages of mineral exploration namely reconnaissance surveys (G4), preliminary exploration (G3) and general exploration (G2) following the guidelines of United Nations Framework Classification (UNFC) and Mineral Evidence and Mineral Content Rules (MEMC-2015) for augmenting mineral resource for various mineral commodities including lithium.
Further, Atomic Minerals Directorate for Exploration and Research (AMDER) has undertaken exploration for lithium in potential geological domains in parts of Karnataka and Rajasthan, the minister informed.
AMDER has also taken up subsurface exploration in Marlagalla area, Mandya district, Karnataka.
Reconnaissance surveys have been also carried out along Saraswati River palaeochannel, in Jodhpur and Barmer districts, Rajasthan for locating lithium mineralisation associated with brine (saline water in salt lakes).
“Preliminary surveys on surface and limited subsurface exploration by AMD, have shown presence of Lithium resources of 1,600 tonnes (inferred category) in the pegmatites of Marlagalla – Allapatna area, Mandya district, Karnataka,” the minister said.
He further informed that under the aegis of Ministry of Mines, a joint venture company named ‘Khanij Bidesh India Ltd. (KABIL) has been formed by three CPSEs namely National Aluminium Company Limited (NALCO), Hindustan Copper Limited (HCL) and Mineral Exploration Corporation Limited (MECL) with equity participation of 40:30:30 respectively, to acquire mineral assets overseas – primarily the critical and strategic minerals including Lithium, Cobalt and others.
KABIL has signed Non-Binding Memorandum of Understanding (MoU) with non-disclosure agreement with three state-owned organizations of Argentina for the purpose of information sharing with respect to prospective mineral acreages.
