MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.
Mine Description
The Derby Tungsten mine is located in sec. 13, T. 20 N., R. 23 E., in the Truckee River canyon just north of U.S. Interstate 80. According to Overton (1947, p. 72) the mine was discovered in 1940 by John Heizer. It was developed by the Rare Metals Corp. in 1940 and 1941, and several hundred tons of ore averaging about 0.5 percent WO3 per ton was produced during the exploration work. The mine has been idle since 1941.
The mine workings consist of a 600-foot adit and shallow surface trenches and pits. The tungsten mineralization occurs as disseminated grains of scheelite in tactite lenses developed along an intrusive contact between granodiorite and Mesozoic metasedimentary rocks. The outcrop area of the pre-Tertiary rocks is small. They are overlain unconformably by Tertiary and Quaternary rocks.
Two shafts, a short adit, and several prospect pits are present in the Hartford Hill Rhyolite and the Alta Formation in the vicinity of the Derby Tungsten mine. Overton (1947, p. 73) states that these workings are part of an old gold prospect known as Rainbow Canyon mines. The work was done many years ago and the prospect has been long idle. There is no record of any production.
