There is a good report on this district by Dings and Robinson (1957, pp. 83-85) USGS Professional Paper 289. They report that pyritic quartz veins up to 50 feet thick cross Chrysolite Mountain. Galena, sphalerite, pyrite, chalcopyrite, calcite, rhodonite, rhodochrosite, barite, and fluorite occur locally. The best ores were strongly oxidized and are typically brown, porous limonite or limonitic quartz with variable amounts of cerussite, calamine, and smithsonite and patches or grains of galena. Free gold reportedly occurs in much of the ore.
