Gold Deposits Goldfo

Secondary Gold Deposits. When primary gold deposits are eroded away by weather (temperature, wind, water) over millions of years, it is referred to as secondary deposits. The gold is flushed out of the rock and accumulates with other heavy minerals as fine gold dust or as small grains, the so-called “nuggets”, in the shallows of streams and
