The Idle Claim, Columbia Red Metals Group is a zinc, copper, arsenic, silver, and lead 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.

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 (Production): Production Notes = No reported production.
Comment (Reference): Primary Reference = Jansons and others, 1984
Comment (Reserve-Resource): Reserves = Inferred reserves are 350 tons at 2.27 percent Zn (Jansons and others, 1984).
Comment (Workings): Workings / Exploration = Development has included an 80 ft long tunnel and open pits. Chip samples contained 370 ppm to 2.85 percent Zn, 205 ppm to 0.7 percent Cu, 4.4 ppm to 22 ppm Ag, 200 ppm to 0.22 percent Pb, and 72 ppm to 16.5 percent As. Low mineral development potential (Jansons and others, 1984).
Comment (Deposit): Model Name = Chugach-type low-sulfide Au-quartz vein ? (Bliss, 1992; model 36a.1 ?)
Comment (Geology): Geologic Description = Two felsic dikes having chalcopyrite, galena, and sphalerite present in shears. Arsenopyrite occurrs within 1/8 inch veinlets in a 15 ft wide felsic dike (Jansons and others, 1984). The felsic dikes intrude sandstone, siltstone, and mudstone of the Tertiary Orca Group.? the chip samples contained 370 ppm to 2.85 percent Zn, 205 ppm to 0.7 percent Cu, 4.4 ppm to 22 ppm Ag, 200 ppm to 0.22 percent Pb, and 72 ppm to 16.5 percent As (Jansons and others, 1984).
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Paleocene or younger; the veins cut felsic dikes which intrude sandstone, siltstone, and mudstone of the Tertiary Orca Group.
