Unnamed (headwaters of Rick's Creek)

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 (Commodity): Gangue = Carbonate

Comment (Deposit): Model Name = Skarn

Comment (Workings): Workings / Exploration = Menzie and Foster (1979) noted the mineral occurrence during geologic mapping.

Comment (Reference): Primary Reference = Albanese,1984

Comment (Geology): Geologic Description = The occurrence noted by Albanese (1984) included the analysis of three samples: 1) a sulfide zone containing arsenopyrite, chalcopyrite, and pyrite. A rock sample from a trench in a garnet-diopside skarn contained 518 ppm Cu, 39 ppm Pb, 436 ppm Zn, 0.1 ppm Au, 1.3 ppm Ag, 1 ppm Mo, 222 ppm Sb, 20 ppm Sn, 60 ppm W, greater than 19,800 ppm As, and 686 ppm Mn; 2) an arsenopyrite-, chalcopyrite-, and pyrite-bearing calc-silicate contained 64 ppm Cu, 4 ppm Pb, 50 ppm Zn, 0.1 ppm Au, 0.4 ppm Ag, 2 ppm Mo, 10 ppm Sb, 4 ppm Sn, 900 ppm W, 213 ppm As, and 1,360 Mn; and 3) an arsenopyrite and pyrite bearing calc-silicate contained 462 ppm Cu, 34 ppm Pb, 37 ppm Zn, 4.3 ppm Ag, 1 ppm Mo, 4 ppm Sn, 450 ppm W, 818 ppm As, and 364 ppm Mn. Weber and others (1978) describe the regional bedrock as quartzite, slate, calc-phyllite and marble. The occurrence is located near the contact of a Tertiary to Cretaceous granodiorite to quartz monzonite intrusion.
