The Four-in-One is a nickel, copper, gold, and silver 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.

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 (Reserve-Resource): Reserves = Hoekzema (1984) reported that the inferred reserves are 33,500 tons at 0.22 percent Cu and 21.2 ppm Ag. The potential for mineral development is low.
Comment (Workings): Workings / Exploration = According to Jansons and others (1984), a 60 ft adit and open pits were present. The U.S. Bureau of Mines (Jansons and others, 1984) reported five chip samples contained from 20 ppm to 3 percent Cu and 2.6 to 46 ppm Ag. Four grab samples contained from 195 ppm to 0.94 percent Cu, 2.7 to 8.8 ppm Ag, and 9 ppm to 0.18 percent Ni. The potential for mineral development is low.
Comment (Reference): Primary Reference = Jansons and others, 1984
Comment (Production): Production Notes = There has been no reported production.
Comment (Exploration): Status = Inactive
Comment (Geology): Geologic Description = Two mineralized shear zones in conglomerate of the Early Tertiary Orca Group range from 5 to 100 ft wide and contain sulfide veinlets and pods of chalcopyrite and pyrite. Five chip samples contained from 20 ppm to 3 percent Cu and 2.6 to 46 ppm Ag. Four grab samples contained from 195 ppm to 0.94 percent Cu, 2.7 to 8.8 ppm Ag, and 9 ppm to 0.18 percent Ni (Jansons and others, 1984).
Comment (Geology): Age = Paleocene or younger based on the age of the bedrock.
