1. Scope
This standard has stated the objectives and tasks, research degree, quality requirements, control degree, feasibility assessment, classification and type of mineral resources/reserves, estimate of mineral resources/reserves.
This standard is applicable to the hard-rock gold mine geologic exploration, the basic construction production mineral exploration in the mine exploration, the examination and approval of the hard-rock gold mine exploration (abandoned-pit) geologic reports.
It has also provides bases for the appraisal and estimation of the hard-rock gold mine resources/reserves during the mining right transfer, stock listing, financing and fund-raising.
