The Competition Creek is a zinc 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.
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 (Reference): Primary Reference = Moore and others, 1986
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Mississippian to Triassic. A potassium argon date indicates that the deposit is Late Mississippian in age.
Comment (Geology): Geologic Description = The Competition Creek prospect is a syngenetic, sedimentary deposit of sulfide disseminations and lenses predominately of pyrite and marcasite, along with some galena and sphalerite. The deposit is in the black shales and cherts of the Kuna Formation (J. Britton, oral communication, 1998). Barite occurs in a shale horizon below the mineralized horizon. In this area, a mafic sill intrudes the Kivalina limestone and shale. The sill is highly propylitized, but appears to have been diorite or gabbro (Moore and others, 1986). The stratigraphic setting at Competition Creek is similar to that at Lik (ARDF number DL005).
Comment (Workings): Workings / Exploration = GCO drilled the property in the early 1980's. The ore is much lower grade than at Lik (ARDF number DL005).
Comment (Deposit): Model Name = Sedimentary exhalative Zn-Pb (Cox and Singer, 1986; model 31a).
