The Pika Canyon 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.

Comments
Comment (Exploration): Status = Active?
Comment (Geology): Age = Tertiary
Comment (Deposit): Other Comments = Pika Canyon prospect is sometimes called Pitka Canyon, but Pitka is a misspelling of the name.
Comment (Deposit): Model Name = Porphyry Cu deposit (Cox and Singer, 1986; model 21a)
Comment (Geology): Geologic Description = The geology at Pika Canyon consists of three main units: Precambrian or early Paleozoic gneiss and schist, Paleozoic phyllite and schist, and Tertiary mafic to felsic volcanic rocks. Many NE-trending faults as well as intense folding dominate the area (Gill, 1977). ? During 1974-1976, soil, rock chip, and stream-sediment sampling were conducted on the prospect by Cities Services Mineral Corp., as well as a ground magnetic survey on a 200- by 500-foot grid (Gill, 1977, p. 2). The soil samples showed anomalous values for copper, zoned in a pattern typical of porphyry-copper deposits in the southwest U.S. (Gill, 1977, p. 87). Pyrite, chalcopyrite, and possibly sphalerite were found in float samples (Gill, 1977). ? the alteration at Pika Canyon is patchy and somewhat irregular, but generally occurs in somewhat concentric zones of potassic, phyllic, and propylitic alteration (Gill, 1977, p. 86).
Comment (Reference): Primary Reference = Gill, 1977
Comment (Workings): Workings / Exploration = During 1974-1976, soil, rock chip, and stream-sediment sampling were conducted on the prospect, as well as a ground magnetic survey on a 200- by 500-foot grid (Gill, 1977, p. 2).
