The Unnamed (headwaters of Rick's Creek) is a tungsten mine located in Alaska.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.
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 = Occurrence noted during geologic mapping.
Comment (Geology): Geologic Description = As reported by Albanese (1984), the occurrence is a pod of gossan containing arsenopyrite, chalcopyrite, and chalcopyrite in calc-silicate rock. Weber and others (1978) describe the country rock as quartzite, slate, calc-phyllite and marble. The occurrence is located near contact of a Tertiary to Cretaceous granodiorite to quartz monzonite intrusion. An assay of a rock sample contained 475 ppm Cu, 3 ppm Pb, 3 ppm Zn, 1.5 ppm Ag, 2 ppm Mo, 5 ppm Sn, greater than 1000 ppm W, 465 ppm As, and 1,330 ppm Mn (Albanese, 1984).
Comment (Reference): Primary Reference = Albanese,1984
Comment (Commodity): Gangue = Calc-silicates
