A nicely presenting native gold miniature in bull quartz with what is likely Arsenopyrite. The Homestake Mine is a classic location which, due to its depth, hosted an experiment which was the first to detect and count solar neutrinos. The discrepancy in results vs expectations created 'the solar neutrino problem' which I am sure is at the center of all your troubles. Perky box mounted. Homestake Mine, Lead, Lead Mining District, Lawrence County, South Dakota, USA. 1" x .6" x 1", .7 oz
