Such oxidized zones are called "gossan," which appears as rusty zones at the surface. Gossans can be a good drilling targets for gold and other precious or base metals.

Look for gold and gold-containing quartz rocks in areas where volcanic hydrothermal activity has taken place in the geologic past. These areas include the regions around old gold mines and rock outcrops upstream from placer gold deposits where gold has eroded out of its bedrock, washed downstream and accumulated in and near stream channels. Examine Rock Outcrops and Fractures. Rock outcrops ...

Sometimes the gold is in a finely divided state, sometimes in particles of considerable size, as nuggets, grains, scales, plates, threads and wires in quartz rock. It occurs also in a finely divided state disseminated through schistose rocks, slates and some sedimentary rocks like limestone. In these cases the rock has been altered by the flow of heated and mineralized waters, often resulting ...

The flowing water tumbles the Gold, giving it its distinct rounded shape. The Gold eventually settles at the bottom of the water, and due to its heaviness remains there. Other nuggets also get caught in the ...
