Unnamed (in upper Cold Creek)

The Unnamed (in upper Cold Creek) is a 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 = Probably inactive

Comment (Reference): Primary Reference = Hummel, 1962 (MF 248)

Comment (Geology): Geologic Description = This locality was identifed as an antimony occurrence by Hummel (1962 [MF 248]). The vein geology and production formerly ascribed to this occurrence by Cobb (locality 26; 1972 [MF463]; 1978 [OFR 78-93]) probably belong to the Bison Lode patented by Henry P. Breen, which is about a half mile southeast of this occurrence (Breen West, NM087). Stibnite is, however, assumed to be present at this location, probably in quartz veins and with some gold values. This occurrence may be similar to quartz-stibnite veins at the Breen West (NM087) and Sliscovich (NM086) mines to the east. The stibnite occurrence is in a marble-rich metasedimentary sequence (Hummel, 1962 [MF 248]; Bundtzen and others, 1994).

Comment (Deposit): Model Name = Simple Sb deposits and low sulfide, Au-quartz vein? (Cox and Singer, 1986; models 27d and 36a).

Comment (Deposit): Model Number = 27d?, 36a?

Comment (Workings): Workings / Exploration = Some antimony claims in the vicinity, including the Hed "&" [and] Strand (NM070) and the Sliscovich (NM086), were located prior to and during World War I, when the region was actively prospected for antimony.

Comment (Geology): Age = Mid-Cretaceous; may be same age as some lode gold deposits of Seward Peninsula.
