Gold Bearing Drill Core
soldAn unusually small (19 mm diameter) drill core sample of high-grade gold quartz vein hosted in a section of chloritic metamorphic rock. Unfortunately there is no locality, however, the geology of the core is consistant with rocks from the Homestake Mine in South Dakota. The specimen was part of the of the Jim Ruder collection. Jim was the head of the Golden Cycle Company, which owned most of the Cripple Creek District.
