Mohave County, Arizona: The Oatman/San Francisco Mining District
July 2019 by Dean Delahaut
The Oatman/San Francisco Mining District’s historic gold production of 2.2 million ounces of gold since the 1880s makes this area Arizona’s greatest primary gold producing district.
Palladium may well be an underexplored element and therefore an opportunity for prospectors and geologists. This is because they are often less than obvious and other than the native metals, a chemical analysis of samples is required to identify PGM-enriched rocks.
It is not necessary to have a PhD in geology, but you need to know the basics, so that’s what I am going to try to dig into here—the understandable basics of these gigantic gold deposits.
Miners are digging again where their forebears once unearthed riches from eight historic mines that honeycomb Sutter Gold Mining Company’s holdings about 50 miles southeast of Sacramento.
Since this position was the least desirable due to the hard physical labor, the bucking room was used as punishment. Do you have a mediocre worker? Bad attitude? Off to the bucking room!
In an old mine that does not have stopes, you know the old miners did not take much if any ore out of that excavation. On the other hand, if you see large stopes within the mine you know that it is these places where the miners found profitable ore deposits within the vein.
The $800 million project will provide 300 jobs during production. It will be the only US mine where nickel is the primary targeted mineral, with about 360 million pounds to be extracted.
In processing gold, silver and other valuable ores, the minerals containing the values, such as metallic gold, silver-bearing sulfides or other minerals, must be freed from the surrounding host rock before those valuable minerals can be captured.
