Goodsprings District- Columbia Mine
AKA: Josephine Claim; Yellow Pine District.
According to the USGS, the Columbia Mine was discovered in 1880. Patera stated that it was discovered in the mid 1880's by Sam Yount. In 1900, a leaching plant was built at Goodsprings to treat copper ore from both the Boss and Columbia mines. This plant was unsuccessful. Patera stated that by 1914, a company headed by Joseph Deidrich owned the mine. From 1921 to 1922, the Columbia Mine was one of several mines in the Goodsprings District that produced Cobalt. The USGS listed Joseph Dederich (Deidrich) as the owner of the mine in 1922. In 1939, Columbia ore was being processed at the Shenandoah Mill. It appears that work and/or exploration were still going on as late as 1975. It was listed as being owned by the St. Antony Mining Company of Nevada. It lists Leonard R. Fayle of Las Vegas as the operator. After 1975, I'm not sure of what activity took place here. Production between 1906 and 1954 included: 327 tons of copper, 6,481 ounces of silver, 30,007 pounds of zinc and 54 ounces of gold. The only known production number that I could find for cobalt was 919 pounds of "cobalt oxide" in 1921.
Last Trip/ Road Conditions: I've been here several times. I believe that the last trip was in 2015. The main road through the district is really good. It's the spur roads leading off to the different mines that vary. I don't remember this spur road being bad. It will be up to you to decide if you go.
