|Location and accuracy||The prospect is located at an elevation of 1,700 feet about a mile southwest of Davis Lake. It is in the NW1/4 section 23, T. 10 N., R. 8 E., of the Seward Meridian. This is location 110 of Condon and Cass (1958), location 75 of Cobb and Richter (1972), location 100 of MacKevett and Holloway (1977), location 161 of Cobb and Tysdal (1980), and location S-128 of Jansons and others (1984). This location is accurate to within a quarter of a mile.|
Geologic descriptionThe prospect consists of stringers and lenses of pyrite-bearing quartz and calcite as much as 1 foot wide in a 2- to 5-foot-wide shear zone. The host rock is slate and sandstone of the Valdez Group of Late Cretaceous age (Cobb and Tysdal, 1980). The shear strikes northeast and dips vertically. Workings on the prospect consist of a small open cut (Johnson 1914 [B 592-G, p. 224-225]). The deposit reportedly contained considerable fine gold, but no assays have been published.
|Geologic map unit||(-147.997949785335, 60.9486230540954)|
|Mineral deposit model||Low-sulfide Au-quartz veins (Cox and Singer, 1986; model 36a)|
|Mineral deposit model number||36a|
|Age of mineralization||Late Cretaceous or younger; the veins cut rocks of the Valdez Group of Late Cretaceous age.|
|Workings or exploration||The workings consist of a single open cut. The deposit reportedly contained considerable fine gold and yielded good assays (Johnson, 1914 [B 592-G, p. 224-225]), but no values have been published. The U.S. Bureau of Mines searched for this prospect in 1979 and 1980 but did not locate it (Hoekzema and Sherman, 1983).|
