Geology of Copper | Properties, Mining, and Formation of Copper
Copper is found alongside many other types of ore. It can be found near gold, silver, zinc, lead, and other types of metal deposits. When mixed in with other ores, copper is not usually found in great abundance. Until the development of the modern copper mining process, it was typically a byproduct of mining for other metals.

Gold and Copper Alloys
Since no change of volume occurs when these alloys are formed, their densities may be calculated from those of gold and copper. The density of standard gold is 17.48, and that of the alloy containing gold 900, copper 100 is 17.16. For the densities of other gold-copper alloys. Many of the alloys have been used for coinage at various times.

Gold-copper ores
The association of gold and copper mineralization in commercially viable ore is a common occurrence. At one end of the spectrum is the predominantly copper ore that contains levels of gold mineralization. This would be uneconomic to mine for its gold content, but the gold provides a significant opportunity value.
