The Bureau of Mines conducted mineral investigations of specific sites in the Hatcher Pass area of the Willow Creek Mining District in Alaska during 1984. The hatcher pass area has produced over 400,000 oz of gold, mainly from lode deposits and some minor placer production. Out of approximately 40 properties in the area, 9 were visited, including several active operations. Random samples were collected for analysis and mineral identification. Discussions with local miners identified several problem areas concerning metallurgy, recovery, and mining feasibility.
