Location and accuracy | This prospect is at sea level in the south bight of Cloudman Bay on Bligh Island. It is located in the SW1/4 sec. 7, T. 12 S., R. 8 W., of the Copper River Meridian. The site is accurately located to within 1000 ft. This prospect is shown as site C-93 in Jansons and others (1984) and as loc. 3 in Cobb (1972: MF-392). |
Geologic descriptionThe country rock at this prospect is slate of the Tertiary Orca Group (Nelson and others, 1985). Capps and Johnson (1915) reported a 20-to 30-foot-wide quartz stockwork zone in the slate carrying chalcopyrite, pyrite, and sphalerite. Capps and Johnson (1913) reported 40 feet of stripping at the site. Samples across a 30 foot width of stockwork ran a few dollars/ton when gold was $20/oz. (Capps and Johnson, 1915). Site could not be located in the early 1980s (Jansons and others, 1984). | |
