Small amounts of gold have been mined in the Shadow Mountains in northeastern San Bernardino County. Gold was discovered here in 1894, and there was some activity for a few years following. There are several quartz veins in granitic gneiss that are associated with aplitic dikes. The ore deposits contain nature gold and varying amounts of copper.
