The gold placers only produced around 50,000 ounces before they were exhausted and attention turned to silver deposits in the 1870s. The USGS report does not mention subsequent gold production as a byproduct of silver and copper ores, but it must have been significant as the county is credited with approximately 2,800,000 ounces. …

Copper is usually found in nature in association with sulfur. Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode.
