|Location and accuracy||The prospect is located in the SW1/4 section 11, T. 2 S., R. 9 E., of the Seward Meridian. It is half a mile east of Reynolds Peak on Latouche Island. Mineralized showings have been prospected at elevations between sea level and 700 feet. The primary mineralized zone occurs at an elevation of 600 feet. This is location 266 of Cobb and Tysdal (1980) and location S-7 of Jansons and others (1984). This location is accurate to within a quarter of a mile.|
The main showing on the prospect consists of a 10-foot-wide mineralized shear zone that contains considerable chalcopyrite. The zone is exposed on a creek bank at an elevation of about 600 feet. Chalcopyrite occurs in stringers and small bunches (Tysdal, 1978 [MF-880-A]). A crosscut is located 50 feet below the exposure, at an elevation of about 550 feet. The host rock consists of graywacke interbedded with slate, argillite, and a small amount of chert, part of the Orca Group of early Tertiary age (Nelson and others, 1985). The rock generally strikes northeast and dips from 40 to 65 degrees west.There are several hundred feet of workings from several adits at elevations from sea level to 700 feet. Johnson (1918 [B 662-C, p. 210-211]) reported a two-compartment shaft on one of the claims and nearby improvements that consisted of two log cabins and mess and bunk houses.
