A CRMA geology term for minerals occurring in a mass or deposit of potential economic interest.
Mineral occurrences are the possible material deposits that exploration may identify and assess. The CRMA definition depends on potential economic interest, but a mineral occurrence is not yet the same as reserves, production capacity, a permitted project, or a verified supply source.
This page is anchored in CRMA Article 2, point 6. It belongs to the geological and exploration layer of the CRMA, before the separate questions of economic viability, permitting, strategic-project status, and supply-chain evidence.

Implementation records should capture the occurrence identifier, deposit location, geological evidence, economic-interest note, raw-material scope, exploration source, and relationship to predictive maps, reserves, project evaluation, or supplier-origin records.
Mineral occurrences are a geological-potential control: the evidence consequence is that early material potential can be recorded as upstream context without overstating reserves, production capacity, permitted project status, or product-level material origin.
