   This Subtopic gives mining-specific guidance on accounting for mineral rights and mining assets within Property, Plant, and Equipment. It clarifies that undeveloped land does not qualify for interest capitalization, how mineral resource asset current costs are measured when current cost disclosures are provided, and—most importantly—that impairment cash flow estimates for mining assets must include value beyond proven and probable reserves (with the related development and extraction outflows) and must reflect market-participant assumptions about mineral price fluctuations.
