Feasibility studies for mining projects

Feasibility studies are required throughout the pre-production stage of every mining project to justify continued investment in the subsequent phase. Usually a concept study or scoping study is followed by one or more pre-feasibility studies that reflect the increasing level of technical and economic knowledge gained at the various earlier stages.

the U.S. mining industry. These mining operations include prospecting, exploration, development, production, mineral processing, environmental restoration and reclamation, and marketing of mineral products. An ore is a mineral or combination of minerals from which useful substances, such as metals, can be economically recovered.


All the costs before the plant is producing gold. Sustaining capex is cost associated with maintaining or upgrading all the equipment and assets throughout the life of the mine. Kalana Mine's total initial capex (aka pre-production capital cost) is $196.3m. The total sustaining capex is $123m. Of this total, $13.9m is mine closure cost.

Mining - Wikipedia

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit.These deposits form a mineralized commodity that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

Step #6 – Mining samples and determining processing. Once mining gets underway, samples must be taken to determine the precise metallurgical qualities of the ore. This is done in order to determine the appropriate processing technique. Step #7 – Processing (on-site) Once ore is extracted, processing it into pure gold must be done.

The true cost of producing an ounce of gold | Provident

These numbers report that the cost of extracting an ounce of gold is actually over $1,000 per ounce, well above the aforementioned numbers. And since gold is currently trading at just over $1,200 per ounce, it explains why mining companies have had less-than-stellar profits. Determining the costs of mining largely depend on the region as well.
