The Hidden Treasure Mine, situated in Dry Canyon within the Ophir Mining District of the Oquirrh Mountains in Tooele County, Utah, is hosted primarily in Mississippian-aged limestone. The ore deposits formed as replacement bodies characterized by valuable metal-bearing mineralization within the folded carbonate strata. Originally located in 1865 by soldiers under General Connor following tips from Native Americans about outcropping boulders, the site was later relocated as the Hidden Treasure in April 1870. It became one of the most productive bonanza mines in the district, actively yielding substantial quantities of silver, lead, copper, and zinc through various periods of intensive nineteenth-century extraction, twentieth-century consolidations, and subsequent operations during World War II.
