Mining methods range from using floating bucket dredges to small diggers. Some of the mining technologies used are similar to those employed during the great gold rushes of the 19th century. Exploration and grade control techniques can be very rudimentary often relying on previous sampling programs or wide spaced bulk sample drill holes.
Successful gold mining under present conditions is a largescale operation, utilizing costly and sophisticated machinery capable of handling many tons of lowgrade ore each day. The grizzled prospector with a burro is no longer a significant participant in the search for mineral deposits, and the small producer accounts for only a minor share of the total production of metals including gold.
Hard rock gold mining extracts gold encased in rock, rather than fragments in loose sediment, and produces most of the world''s gold.
