Palmer Creek No. 2 Occurrence, Hope District, Kenai Peninsula Borough, Alaska, USA

This page is currently not sponsored. Click here to sponsor this page.
 
 
Location: This occurrence is located in the SE1/4 section 14, T. 8 N., R. 2 W., of the Seward Meridian. It is at an elevation of 2,900 feet, on the west fork of Palmer Creek. This is location 25 of Tysdal (1978 [MF-880-A]) and location S-291 of Jansons and others (1984). The location is accurate to within a quarter of a mile.
Geology: The deposit consists of abundant thin quartz veins cutting graywacke of the Valdez Group of Late Cretaceous age (Nelson and others, 1985). The veins generally strike N62W to N85W and dip steeply to the north (Hoekzema and Sherman, 1983). They are intermittently exposed from this site southward for about 2 kilometers. A single grab sample collected by the U.S. Geological Survey contained 3 ppm silver, 10 ppm beryllium, and 370 ppm copper (Tysdal, 1978 [MF-880-A]). Samples collected by the U.S. Bureau of Mines assayed 0.09 ounce of silver per ton and 4 percent copper (Jansons and others, 1984).
Workings: The occurrence was first reported and sampled by Tysdal (1978 [MF-880-A]), who collected a grab sample that contained 3 ppm silver, 10 ppm beryllium, and 370 ppm copper. Samples collected by the U.S. Bureau of Mines contained 0.09 ounce of silver per ton, and 0.04 percent copper (Jansons and others, 1984). Trenches are reported nearby, but here there are no workings or improvements present.
Age: Cretaceous or younger; the veins cut rocks of the Valdez Group of Late Cretaceous age.

Commodities (Major) - Ag; (Minor) - Be, Cu
Development Status: None
Deposit Model: Low-sulfide Au-quartz veins (Cox and Singer, 1986; model 36a)
