Pika Canyon prospect is sometimes called Pitka Canyon, but Pitka is a misspelling of the name.
Location: The Pika Canyon prospect is located in sections 29, 30, 31, and 32, T.24 N., R. 21 E., of the Copper River Meridian, it covers about 2 square miles. It is location 7 of Singer and others (1976), and location 12 of Eberlein and others (1977). It lies directly west of the Fishhook prospect (TC009) and 3 miles south of Liberty Creek. The location is accurate to within 1/2 mile.
Geology: 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).
