Mineral investigations in the Colville Mining District and Southern National Petroleum Reserve in Alaska. Open file report (Final)
1995
The U.S. Bureau of Mines conducted a five-year mineral resource assessment of the 16.6 million acre Colville Mining District in northern Alaska, which includes part of the National Petroleum Reserve in Alaska. During fieldwork, 1593 rock, soil, and stream sediment samples were collected and four bulk samples taken for beneficiation studies. A total of 40 mineral occurrences were documented, including 27 which were previously undescribed. Moderate potential exists for development of zinc-lead-silver, barite, and phosphate deposits.
