Platinum deposits of Alaska

The placer deposits of the Goodnews Bay district in southwestern Alaska have yielded the only significant production of platinum metals in the United States, although small amounts of platinum metals have been produced from other deposits in Alaska and elsewhere in the United States. The Goodnews Bay deposits were described by Mertie in U.S. Geological Survey Bulletin 918 (1940). Many new data have been obtained since that time, and in order to make this information available in advance of publication, this report on Platinum deposits of Alaska has been placed on open-file.
