The Geological Survey of India has for the first-time established Lithium ‘inferred’ resources) of 5.9 million tonnes in Salal-Haimana area of the UT of Jammu & Kashmir

What are Inferred Resources?

The “inferred” mineral resource is a resource for which quantity, grade and mineral content are estimated only with a low level of confidence.
It is based on information gathered from locations such as outcrops, trenches, pits, workings and drill holes that may be of limited or uncertain quality, and also of lower reliability from geological evidence.
It is based on the classification from United Nations International Framework Classification for Reserves/Resources – Solid Fuels and Mineral Commodities of 1997 (UNFC-1997).
Lithium (Li), sometimes also referred as ‘White gold’ due to its high demand for rechargeable batteries, is a soft and silvery-white metal.
Lithium can be extracted in different ways, depending on the type of the deposit — generally either through solar evaporation of large brine pools, or from hard-rock extraction of the ore.
Lithium is an important component of electrochemical cells used in batteries of EVs, Laptops, Mobiles etc.
It is also used in thermonuclear reactions.
- It is used to make alloys with aluminium and magnesium, improving their strength and making them lighter.
  - Magnesium-lithium alloy - for armour plating.
  - Aluminum-lithium alloys - in aircraft, bicycle frames and high-speed trains.
Major Global Lithium Reserves:
- Chile > Australia > Argentina are top countries with Li reserves.
- Lithium Triangle: Chile, Argentina, Bolivia.
- Lithium Reserves in India:
  - Preliminary survey showed estimated lithium reserves of 14,100 tonnes in a small patch of land surveyed in Southern Karnataka’s Mandya district.
  - Other potential sites:
    - Mica belts in Rajasthan, Bihar, Andhra Pradesh.
    - Pegmatite belts in Odisha and Chhattisgarh.
    - Rann of Kutch in Gujrat.
