MoreGold reserves are finite, and pulling new gold out of the ground can be very expensive. In fact, it is common to hear industry insiders cite $1,200 as the all-in cost for mining a single ounce of gold. Cost Reporting Debate—Does It Really Cost $1,200 to Mine One Ounce? The $1,200 price tag is still questioned by investors and industry insiders.

MoreWorldwide there are over 43 million artisanal miners in virtually all developing countries extracting at least 30 different minerals. Gold, due to its increasing value, is the main mineral extracted by at least half of these miners. The large majority use amalgamation either as the final process to extract gold from gravity concentrates or from the whole ore.
