Define 'stock' and 'reserve' of mineral resources and give one example of each found in India.
Answer
Stock – known mineral quantity not yet economically viable for extraction (e.g., bauxite in Odisha); Reserve – portion of the stock that is currently economically recoverable (e.g., iron‑ore reserves in Goa).
Step-by-step solution
- State the definition of 'stock' as the total known amount of a mineral irrespective of economic feasibility.
- Provide an Indian example of a mineral stock, such as bauxite deposits in Odisha.
- Define 'reserve' as the part of the stock that can be mined profitably with present technology and market conditions.
- Give an Indian example of a reserve, for instance iron‑ore reserves in Goa.
- Combine the definitions and examples into a single concise answer.
Common mistake: Confusing stock with reserve or giving the same example for both categories.
Concept tested: Mineral stock vs reserve
