The Mineral mining district was so-named after prospectors discovered rhyolite-hosted silver-copper-lead-zinc-bearing replacement mineralization in the area during the 1870s. A town site was established, and small-scale mining began in the 1880s and continued in earnest until the repeal of the Sherman Silver Purchase Act by U.S. President Cleveland in 1893, which caused a collapse in the silver price and decimated the silver mining industry. The mines and smelters at Mineral shut down at that time, and subsequent mining was very sporadic and conducted at a small scale through to 1950. The district has been essentially dormant ever since, apart from a few years of historical exploration during the late 1960s/early 1970s, but has never had a modern, systematic exploration approach applied to it.
