2) Identify resources. Refers to the sum of solid mineral resources discovered through exploration. According to the geological reliability and feasibility evaluation, different results can be divided into three categories: reserves, basic reserves and resources.
3) Potential mineral resources. It refers to the part of solid mineral resources that has not been verified according to the geological basis and geophysical and geochemical anomaly prediction.
4) the amount of resources. Refers to the identification of some mineral resources and potential mineral resources. Including mineral resources that have been proved as sub-marginal economy through feasibility study or pre-feasibility study, internal economic mineral resources that have not been verified through feasibility study or pre-feasibility study, and mineral resources predicted after pre-investigation.
5) Basic reserves. Refers to the identification of a part of mineral resources. It can meet the index requirements of current mining production (including grade, quality, thickness and mining technical conditions, etc.). ), and it is proved by detailed investigation, exploration and control, and it is considered as economic and marginal economy by feasibility study and pre-feasibility study, and it is expressed by the quantity without deducting design and mining losses.
6) Reserve. Refers to the economically recoverable part of basic reserves. During the pre-feasibility study or the preparation of the annual mining plan, it was studied and revised by factors such as economy, mining, mineral processing and metallurgy, environment, law, market, society and government, and the results showed that it was economically recoverable or exploitable at that time. According to the different stages of geological reliability and feasibility evaluation, it can be divided into recoverable reserves and pre-recoverable reserves.
