The depth of the deposit is crucial
And for the mineralisation to be as long as possible, the deposit must be deep -- 3 km from the surface -- to guarantee a certain degree of insulation and a long magma life." Chiaradia observed that less than 1% of the gold is captured in the ores in the deep copper-rich deposits.
What depth is gold found?
These gold deposits lie at a depth between 1200 and 4500 metres and were created due to mountain formation. They exist in marine sediments (marine deposits) or metamorphic rock (created deep in the earth's crust by high temperature and pressure).
Gold is primarily found as the pure, native metal. Sylvanite and calaverite are gold-bearing minerals. Gold is usually found embedded in quartz veins, or placer stream gravel. It is mined in South Africa, the USA (Nevada, Alaska), Russia, Australia and Canada.
