|Location and accuracy||The Alaska Atlin prospect is at an elevation of approximately 50 feet on the southwest shore of Gastineau Channel on Douglas Island, just south of the mouth of Ready Bullion Creek. It is in the SE1/4SE1/4 section 6, T. 42 S., R. 68 E. of the Copper River Meridian. The location is accurate.|
The Alaska Atlin prospect was discovered in 1901 and was developed by an adit and two short shafts (Redman and others, 1989). The prospect is in black phyllite that contains concordant quartz veins. The quartz veins contain pyrite. U.S. Bureau of Mines samples contained no significant gold values (Redman and others, 1989).The rocks in the general area are Upper Jurassic or Cretaceous marine argillite and graywacke, interbedded with andesite or basalt (Brew and Ford, 1985). The bedded rocks are regionally metamorphosed to prehnite-pumpellyite or greenschist grade, and cut by diorite or gabbro dikes and sills.
