Location: The prospect is situated in the NE1/4 section 15, T. 2 N., R. 1 W., of the Seward Meridian. It is located on a small point of land on the east side of Lost Lake. The portal is at an elevation of about 1,900 feet about 35 feet from the shore of the lake. This is location 84 of Cobb and Tysdal (1980) and location S-209 of Jansons and others (1984). This location is accurate to within 300 feet.
Geology: The prospect consists of quartz stringers and pods as much as 6 inches wide in a 2- to 4-foot-wide shear zone. The zone strikes N10E and dips 70E (Hoekzema and Sherman, 1983). The host rock is slate and sandstone of the Valdez Group of Late Cretaceous age (Cobb and Tysdal, 1980). The host rock strikes N18E and dips vertically (Martin and others, 1915). Mineralization consists of abundant arsenopyrite and lesser amounts of chalcopyrite, galena, pyrite, sphalerite, and gold. Gold occurs free in the quartz and in the sulfide minerals (Martin and others, 1915). The sulfide mineralization appears to pinch out completely in the adit (Hoekzema and Sherman, 1983). Workings on the prospect consist of a 5- by 30-foot open cut and a 28-foot-long adit at its north end (Hoekzema and Sherman, 1983). Two samples assayed 3.5 ounces of gold per ton and 10.3 ppm gold along with 3,500 and 6,500 ppm arsenic, respectively (Hoekzema and Sherman, 1983). The first sample was a 4-inch-wide chip sample of a quartz vein exposed in the open cut. The second sample was a grab sample from the dump.
Workings: Workings on the prospect consist of a 5- by 30-foot open cut and a 28-foot-long adit at its north end (Hoekzema and Sherman, 1983). The open cut and adit both strike N2E. Two samples assayed 3.5 ounces of gold per ton and 10.3 ppm gold along with 3,500 and 6,500 ppm arsenic, respectively (Hoekzema and Sherman, 1983). The first sample was a 4-inch-wide chip sample of a quartz vein exposed in the open cut. The second sample was a grab sample from the dump.
Age: Cretaceous or younger; the veins cut rocks of the Valdez Group of Late Cretaceous age.
Reserves: The U.S. Bureau of Mines estimated a resource of 10 tons of ore containing 1 ounce of gold per ton and 0.5 ounce of silver per ton (Hoekzema and Sherman, 1983).
