Geology of the Northeast Needlepoint Mountain and Erickson Mine Areas, Northern British Columbia* (104p/4)

چکیده
As part of a 3.year program of geologic mapping from the Yukon border south through the Midway, Cassiar and Erickson mining camps (Nelson and Bradford, 1987a; 1987b; 1989, this volume; Nelson et al. 1988a; 1988b), I:25 000.scale mapping was conducted in the northeast quarter of the Needlepoint Mountain (104P/4) map area during the 1988 field season (Figure l-35-1). Since Gabrielse’s ( 1963) original I:250 000~scale McDame map, excellent but schematic geologic maps by Diakow and Panteleyev (1981), Gordey er al. (1982), and Panteleyev and Diakow (1982), have served as the only available detailed maps of this area. Consequently, the objectives of this project are: 0 To map the geology of the study area in detail. 0 To identify, map, and date significant lithotectonic units within the Sylvester allochthon. 0 To examine the structural and stratigraphic setting of the Erickson deposit in the context of the geology and geologic history of the study area.

The Eskay Creek gold-silver mine, located in northwest British Columbia, is the highest-grade precious-metal volcanogenic massive sulphide deposit in the world. The mining industry continues to spend more than $2 million each year on exploration for similar deposits in the area. The geologic setting at the minesite is well studied, but large tracts in north-central British Columbia require more...

The Eskay Creek gold-silver mine, located in northwest British Columbia, is an unusually high-grade ore deposit. The mining industry continues to spend more than $2 million each year on exploration for similar deposits in the area. The geologic setting at the minesite is well studied, but large tracts in north-central British Columbia require more detailed surveys to determine if favourable sit...
