GOLD RUSH: Gold and Gossan
Gold in the San Juan Mountains of ColoradoAs a gold prospector you should immediately notice the mine dumps, lack of trees growing on the yellow, brown, reddish brown and tawny colored rock and soil known as gossanIt's obvious that these gossans were mined in the past, but look at all of the exposed gossan in the high peaks that have not been minedIt is likely there are several rich goldGossans provide excellent places to search for gold, since limonite produced by the oxidation of goldbearing pyrite, may contain specs, rods, or masses of visible gold The better places to look for visible gold in gossans are in weblike, honeycomb, vuggy zones known as boxworks Boxworks result from oxidation and removal of the pyrite, leavinggold in limonite
