Location: The Columbine prospect is at an elevation of about 1,400 feet, at the east end of the larger of two lakes at the head of Cann Creek. The prospect is 0.4 mile southeast of the center of sec. 22, T. 45 S., R. 56 E. It is location P-16 of Bittenbender and others (1999) and MAS no. 0021140084 (U.S. Bureau of Land Management, 2002).
Geology: Johnson and Karl (1985) map the rocks in the area of this prospect as a stock of Cretaceous or Jurassic diorite. The stock is cut by diverse faults, the most prominent of which is the Peril Strait Fault, a regional-scale, northwest-striking, high-angle fault that truncates the stock on the northeast. Bittenbender and others (1999), citing Buddington (1925), report that this prospect is an auriferous quartz vein. No other information about the prospect has been made public. Isotopic studies indicate that the gold-quartz veins in coastal southern and southeastern Alaska are Eocene, about 50 Ma in age (Haeussler, 1995; Goldfarb, 1997; Goldfarb and others, 1997).
Age: Isotopic studies indicate that the gold-quartz veins in coastal southern and southeastern Alaska are Eocene, about 50 Ma in age (Haeussler and others, 1995; Goldfarb, 1997; Goldfarb and others, 1997).
