Geology: The geology at the NE Pika Canyon prospect consists of three main units: Precambrian or early Paleozoic gneiss and schist; Paleozoic phyllite and schist; and a Tertiary mafic volcanic unit. The igneous rocks within the prospect area range in composition from felsic to mafic. 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, 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 and zinc, but it is uncertain whether the anomalies represent zoning related to a structurally controlled copper-zinc deposit (Gill, 1977, p. 87). Cities Services Mineral Corp. also drilled two holes on the property in 1976 (Cities Services Mineral Corp. Annual Labor Reports, unpublished claim reports, 1976).
Workings: During 1974-1976, soil samples, rock chip samples, and stream-sediment samples were taken, and a ground magnetics survey was conducted. The soil samples and the survey were taken on a 200 by 500 foot grid (Gill, 1977, p. 2). NE Pika Canyon has probably been explored further since 1977.
