Mineral Resources — Ecological Framework

Ecological Framework

Keep the stages distinct. A discovery or resource estimate does not establish a producing mine, and an operating mine does not necessarily provide domestic refining capacity. USGS's 2025 Appendix C treats reserve estimates as dynamic because exploration, costs, prices and technology can change what is economically recoverable.

For a hypothetical million tonnes of ore at one-per-cent grade, contained metal is ten thousand tonnes. Eighty-per-cent recovery yields eight thousand tonnes. Ore tonnage, contained metal and recovered output use different bases, and comparing them as though they were identical exaggerates supply.

A reserve-to-production ratio is a dated snapshot. One hundred units divided by five units per year gives twenty years at those unchanged values, not a certain exhaustion date. Discoveries, reassessment, demand, recycling and production changes can alter the trajectory.

Criticality combines importance with supply risk. Mining concentration, refining dependence, substitutes and development timelines matter alongside geology. India's National Critical Mineral Mission was approved on 29 January 2025, with ₹16,300 crore expenditure distinguished from ₹18,000 crore expected PSU and other investment.

The programme covers exploration through processing and end-of-life recovery. These approval figures are not proof of completed spending or output. A complete strategy considers responsible primary production, diversified access, demand efficiency and feasible recycling, including the environmental and social conditions of each route.
