Gold mining in Arizona has a long history. From 1860 to 1965, Arizona mines produced 13,321,000 ounces of gold.
The Arizona Geological Survey (AZGS) has now compiled “some of the most significant publications [about gold mining and gold deposits], scanned them, produced PDF files, deployed an optical character recognition filter to facilitate word searches” and has posted them on its website for free download.

You can see production by county here. That page briefly describes gold districts within the counties.
You can read about mining scams here, a report from the now defunct State Department of Mines and Mineral Resources. The site is now maintained by AZGS.
Arizona is blessed with abundant mineral resources, see map below.
