Nimrod

The Nimrod is a silver and gold 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 (Exploration): Status = Active

Comment (Deposit): Model Name = Polymetallic vein (Cox and Singer, 1986; model 22c)

Comment (Deposit): Other Comments = Similar to the Nimbus prospect (HE075); some references combine the two as one site.

Comment (Geology): Age = Probably Late Cretaceous, assuming that the deposit is contemporaneous with the Golden Zone and satellite deposits (HE043, HE040, etc.).

Comment (Reference): Primary Reference = Hawley and others, 1978

Comment (Geology): Geologic Description = The country rocks in the area of the Nimrod prospect are Devonian ophiolite and Upper Devonian to Triassic tuffaceous chert, volcanic conglomerate, volcanic mudstone, basaltic breccia, graywacke, and limestone (Wilson and others, 1998). The Nimrod prospect consists of sulfide-bearing, quartz-matrix breccia poorly exposed for 200 to 300 feet along a strand of the Chulitna fault. The sulfide minerals are arsenopyrite, chalcopyrite, pyrite, sphalerite, and stibnite. Samples contain up to 3 ounces of silver per ton, in addition to lead, zinc, antimony, and gold (Hawley and others, 1978). The deposit is similar in mineralogy and structure to the Golden Zone and satellite deposits (HE043, HE040, etc.).

Comment (Workings): Workings / Exploration = There are minor surface workings. Samples contain up to 3 ounces of silver per ton, in addition to lead, zinc, antimony, and gold (Hawley and others, 1978).
