Epithermal Gold for Explorationists AIG Journal

Evaluation of some epithermal quartz gold-silver systems identified in this manner has led to the discovery of larger gold deposits of other styles (e.g., Porgera, Emperor). Carbonate-base metal gold deposits should be tested for associated epithermal quartz gold-silver mineralisation which has the potential to provide elevated gold grades.

Photos of Natural Silver Ore, Silver minerals, Crystal

Gold and silver are obtained from a variety of ores, in some of which the gold predominates, in others silver is the primary value, while in still a third class these two metals may be mixed with the base metals, such as lead, copper, zinc, and iron. Few silver ores are absolutely free from gold, and vice versa, so that a separate consideration

Copper, Silver and Gold ScienceDirect

Jan 01, 1997· This chapter discusses the history, abundance, distribution, and production of copper, silver, and gold. Silver is widely distributed in sulfide ores, of which silver glance or argentite is the most important. Gold is widely and sparsely distributed both in native and in tellurides, and is almost invariably associated with quartz or pyrite.

Wisconsin Geological & Natural History Survey » Gold

At Davis Hill, the gold was found in a conglomerate that also showed some silver and copper values (WGNHS files). CLARK COUNTY: A trace of gold was detected by assay of a quartz vein cutting a talc and chlorite bearing schist “from Clark County.” Associated minerals were pyrite, magnetite, and arsenopyrite (Irving, 1874b).

Gold in Quartz February 2016 (Vol. 85, No. 06) ICMJ's

Free gold in quartz veins comes in all sizes, with a full range of gold particles from obvious stuff easily visible to the eye down to gold that can barely be seen with a magnifying glass. The coarser stuff can be found with a metal detector, while the smaller sized gold requires that the rock be crushed and the resulting powder panned.
