The Otter Lake is a copper 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.

Comment (Geology): Geologic Description = West of Otter Lake, chlorite schists contain interbedded argillites, cherts, and recrystallized limestone. The schist contains disseminated chalcopyrite in massive pyrite. Within the Lake Clark schist belt. MacKevett and Holloway (1977) describe the rocks as Paleozoic (?) schists, largely of volcanic derivation; inlcudes both mafic and felsic volcanic schist. Felsic meta-volcanic rocks northeast of Portage Lake (located NW of Otter Lake) are considered to be a favorable host for network type copper-zinc deposit (Resource Associates of Alaska, 1976). Limestone beds are common hosts for mineralization.?
Comment (Geology): Age = Host is Paleozoic
Comment (Geology): Age = Host rock is Paleozoic.
