Mine Info
Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Workings): Workings / Exploration = Samples of quartz-bearing veins contain up to 0.56% Cu.
Comment (Reference): Primary Reference = Meyer and Kurtak, 1992, USBM OFR 75-92
Comment (Deposit): Model Name = Sandstone-hosted Cu
Comment (Geology): Geologic Description = Outcrops of sandstone and siltstone of the Kanayut Conglomerate are cut by sulfide-bearing anastomosing quartz veins that trend north-south and are exposed for 60 meters along strike. Chalcopyrite was the only sulfide identified, and it occurs with associated malachite and azurite stain.
