This is the northwesternmost auriferous quartz vein occurrence within the zone of lode mineralization that appears to have been the source for the gold placers in the Porcupine area that includes Porcupine Creek (SK041), McKinley Creek (SK045), Cahoon Creek (SK044), and Glacier Creek (SK065).
Location: These quartz veins are apparently about 1/2 mile south of Mount McDonell on the Canada-United States border. Their location is approximate and they may actually be on the Canadian side of the border. This is location 38 of Berg and others (1981). Smith (1932) refers to a Stampede group of claims,'... adjacent to the international boundary north of Haines, both in Canada and in Alaska.' Eakin's (1918; 1919) mention of gold-quartz ledges at an elevation of about 4,500 feet in the mountains north of the lower end of the Jarvis Glacier apparently applies to mineral occurrences in Canada, immediately west of the International border.
Geology: This prospect consists of gold quartz veins in a granitic country rock about 300 feet above its contact with limestone. The lower and apparently richest vein varies from 1 to 4 feet in width and is traceable for 2,000 feet along strike. Assays are reported to have been from a few dollars to $70 per ton in gold (up to about 3.5 ounces per ton). The best values were from the narrower portions of the vein and most samples contained a few ounces of silver per ton (Eakin, 1918; 1919). The veins must be younger that the Cretaceous quartz diorite to granodiorite which they cut (MacKevett and others, 1974).
Workings: The Alaska Juneau Gold Mining Company explored the claims and dropped their option in 1929 due to, 'unsatisfactory results' (Eakin, 1918).
Age: Cretaceous or younger based on the age of the quartz diorite to granodiorite that hosts the veins (MacKevett and others, 1974).
