|Location and accuracy||This prospect is about one mile northeast of Golden at an elevation of 1,150 feet. It is within the SE1/4 section 2, T. 10 N., R. 8 E., of the Seward Meridian. This is location 98 of Condon and Cass (1958), location 80 of Cobb and Richter (1972), location 96 of MacKevett and Holloway (1977), location 153 of Cobb and Tysdal (1980), and location S-134 of Jansons and others (1984). This location is accurate to within a quarter of a mile.|
Geologic descriptionThe prospect is hosted in sheared graywacke and slate of the Valdez Group of Late Cretaceous age (Cobb and Tysdal, 1980). The shear strikes N80E and dips 60N. At one place a quartz lens, 10 to 18 inches wide and traceable for 45 feet, fills the entire shear. About 50 feet farther uphill, a 25-foot open cut exposes a 10-inch shear containing 8 inches of quartz. Johnson (1914 [B 592-G, p. 221-222]) reported a few fine colors were obtainable from this quartz by panning, but no assay results are reported. The workings on the prospect consist of minor surface stripping.
|Geologic map unit||(-147.97355011052, 60.98063058426)|
|Mineral deposit model||Low-sulfide Au-quartz veins (Cox and Singer, 1986; model 36a)|
|Mineral deposit model number||36a|
|Age of mineralization||Cretaceous or younger; the deposit is in a shear zone that cuts rocks of the Valdez Group of Late Cretaceous age.|
|Workings or exploration||Johnson (1914 [B 592-G, p. 221-222]) reported minor surface stripping and that a few fine colors were obtainable from panning the veins. No assay values were reported. The U.S. Bureau of Mines searched for the prospect in 1979 but did not find it (Hoekzema and Sherman, 1983).|
