|Location and accuracy||This occurrence is located at or near the shore of the Alaska Peninsula at the east end of Ramsey Bay. The map site is 2,000 feet east of triangulation station Lou. The location is accurate to within 500 feet.|
Geologic descriptionThis occurrence consists of a series of northeast-trending sulfide-carbonate-chalcedony veins 150 to 300 feet apart that range up to 20 feet thick (Retherford and Hickok, 1990). The veins are thought to be controlled by a series of high-angle faults cutting andesite porphyry of the Eocene to Oligocene Meshik Formation. Alteration consists of illite-sericite halos bordering the veins. Eight rock-chip or channel samples contained 142 to 544 ppb gold.
