ICMM • Where and how does mining take place?

The results of this process are measured in terms of mineral resources and ore reserves. Mineral resources refer to the concentration of materials in or on the earth's crust that have reasonable prospects for economic extraction. Ore reserves are those parts of a mineral resource that can be economically mined. For more.
