The Cerro Colorado Claims Group lies within one of the oldest producing mining districts in Arizona with small, scattered, relatively shallow mines and prospects active intermittently from at least the 1770’s to about 1950. Total estimated and recorded production has been some 4,500 tons of ore containing approximately 376,000 ounces silver, 460 ounces gold and small amounts of copper and lead.

Mineralization in the district is epithermal quartz-fissure veins with minor base metal sulfides and mercury-bearing tetrahedrite. Silver and gold enrichments occur in oxidized zones. Host rocks are a complex of cretaceous quartz latite and andesite porphyry and andesite porphyry flows and tuff with some inter-bedded sedimentary beds, invaded by Laramide andesite porphyry, rhyolite and dioritic plugs and dikes.
