Location: The mine is located on the east side of Kenai Lake at an elevation of 1,700 feet. It is about 1.2 miles north of Victor Creek. It is situated in the SE1/4 section 6, T. 3 N., R. 1 E., of the Seward Meridian. This is location 77 of Tysdal (1978 [MF-880-A]), and location S-221 of Jansons and others (1984). This location is accurate to within 300 feet.
Geology: The rock at the mine consists of a sheared quartz vein that ranges between 1.5 and 5 feet wide; it averages 2.5 feet wide (Martin and others, 1915). The vein strikes N60E and dips 80N. It is exposed for 300 feet above the main adit (a 200-foot-long adit at an elevation of 1,680 feet ) and can be traced along strike for about a mile to the 5,000 foot elevation where there is another adit (65 feet long). At an elevation of 5,000 feet, the vein is 2.5 inches wide. The vein is cut twice by well-defined north-south vertical faults that are exposed in the main adit. The country rock consists of slate of the Valdez Group of Late Cretaceous age that strikes N30-40E and dips 80W (Nelson and others, 1985; Hoekzema and Sherman, 1983). Metallic minerals are concentrated along fractures in the vein and consist of arsenopyrite, chalcopyrite, galena, pyrite, and sphalerite; gold is also present (Martin and others, 1915). Nine grab samples collected from the lower adit assayed between a trace and 0.14 ounce of gold per ton and 0.02 to 0.73 ounce silver, along with as much as 10,000 ppm arsenic (Jansons and others, 1984).
Workings: Mine workings consist of two adits: a 200-foot-long adit at an elevation of 1,680 feet and a 65-foot adit at an elevation of 5,000 feet. Nine grab samples collected from the lower adit assayed between a trace and 0.14 ounce of gold per ton and 0.02 to 0.73 ounce silver, along with up to 10,000 ppm arsenic (Jansons and others, 1984).
Age: Cretaceous or younger; the vein cuts rocks of the Valdez Group of Late Cretaceous age.
Production: Recorded production is 65 ounces of gold (Hoekzema and Sherman, 1983).
Reserves: Reserves are estimated at 7,400 tons of ore with a grade of .023 ounce of gold per ton and 0.225 ounce of silver per ton (Hoekzema and Sherman, 1983).
