Investigation of the Bailey Copper Prospect, Willow Creek Mining District, South-Central Alaska.
This prospect is in the southwest corner of the Talkeetna Mountains about 45 airline miles northeast of Anchorage. Numerous gold mines and gold and molybdenum prospects in the area make it potentially important. Bornite, chalcopyrite, covellite, molybdenite, gold, and silver occur in a shear zone in quartz diorite. The shear zone appears to be about 200 feet wide and at least 1,500 feet long; glacial debris, rubble, and talus cover most of it; disseminated mineralization can be observed in bedrock exposed over an area about 50 feet wide, 500 feet long, and over a vertical distance of about 300 feet. A drilling program would be necessary to determine the size, grade, and character of the deposit.
