In the extremely weathered gossans exposed at surface or in exploration pits goethite hematite and scorodite are present as pseudomorphs of oxidized arsenopyrite which can be used as a visual pathfinder for goldarsenic mineralization4127
Residual soil mantles represent only a small portion of the original primary goldbearing hardrock vein material They have concentrated in place as seam diggins on a dry hillside while rainfall wind gravity and other agents carry away the lighter soluble minerals such as calcium potassium and sodium that are abundantly found in3199
Gossans are the oxidized sulfiderich parts of veins and other mineral deposits that have a distinct rusty appearance These gossans offer excellent visual guides in the search for gold and other mineral deposits In any historic mining district you will often find dozens if not hundreds of old prospect pits dug into the rusty rocks4889
Secondary gold remobilization in such deposits can often be attributed instead to gold complexing by sulphurbearing ligands Gold and silver solubility in the systems Au S O2 H2O and Ag S O2 H2O3103

Gold and silverbearing gossans were originally mined in these districts during the 1860s Later from the 1890s to about 1920 copper and zinc ores were mined in large quantities and treated in several nearby smelters The minerals that have resulted from the alteration of the primary copper ore include limonite wad chalcopyrite bornite4191
