| Location and accuracy | The NE Pika Canyon prospect is located in section 22, T. 24 N., R. 21 E., of the Copper River Meridian and covers an area of about 1 square mile. It is located just to the northeast of Pika Canyon prospect (TC023), and two miles north of Fishhook prospect (TC009). The location is accurate to within 1/2 mile. |
Geologic descriptionThe 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 Annual Labor Reports, unpublished claim reports, 1976).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 or exploration | 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. |
