The project economics of gold deposits are mostly dependent on two major factors: size and grade. Without a sizeable ore body, a mining operation cannot acquire the economies of scale to bring down the cost of production. Likewise, a project without grade may not have the margins for each ton of ore processed to justify production.

Hydrogeochemical prospecting for gold: Groundwater collected from wells, springs, and drill holes may provide clues to the presence of subsurface gold deposits. As groundwater flows through the deposit, minute amounts of gold are leached from the rocks. These can sometimes be detected in groundwater samples collected from wells located down gradient from the deposit.
Gold mining is a global business with operations on every continent, except Antarctica, and gold is extracted from mines of widely varying types and scale. At a country level, China was the largest producer in the world in 2018 and accounted for around 12 per cent of total global production.
