Proportion of reserves of mercury-containing ore bodies at all levels

It is not required to explore Class B reserves during the geological exploration stage of mercury deposits. The proportion of C-level reserves should be determined according to the possible construction scale of the mine scale.

For large and medium-sized deposits, the proportion of C-class reserves is 30-50% of the total reserves, generally not less than 20%. For the satellite mines near the ore body, the prospective reserves obtained are also included in the total reserves of the deposit, and those who are far away from the ore bodies are not included. For the ore fields where multiple small deposits are concentrated, the total reserves of the C-class are measured and calculated according to the ore field. An independent extension of a small deposit or an extension of a production deposit does not require exploration of Class C reserves.
