Mineral Resources (M&I, Inferred)
RegulatoryGeologically demonstrated mineralization, classified by confidence level.
Detail
Mineral Resources are geologically demonstrated mineralization, classified into three confidence levels: Measured (tight drill pattern, high certainty), Indicated (wider pattern, good certainty), Inferred (extrapolated from few drill holes, lowest certainty). Mineralis treats Inferred resources more conservatively than M&I in the Geology sub-score because they may not be cited in cash-flow models. M&I + successful feasibility = Proven-and-Probable Reserves.
