The gold can be mined from the rocks through tunnelling, but it is difficult. Machines called stamper batteries were used to crush the rock, and the chemical cyanide helped to separate out the gold. Alluvial gold comes from the rocks once they have been worn down to sand and gravel over many thousands of years by rivers or glaciers.
