Results of the U.S. Bureau of Mines Colville Mining District Study, 1991

摘要

The U.S. Bureau of Mines is conducting a four-year study to assess the mineral resources and the mineral development potential of the Colville Mining District. This study is part of the Bureau's ongoing statewide mining district evaluation program. The mining district is in northern Alaska and includes the Colville River drainage basin and a part of the southern National Petroleum Reserve - Alaska. Section 105(c) of the Naval Petroleum Reserves Act of 1976 mandated that a mineral inventory of the petroleum reserve be completed. During 1977 and 1978, the USGS conducted preliminary regional geologic mapping and regional geochemical sampling while the Bureau conducted site-specific examinations and detailed sampling of identified mineral occurrences. This report summarizes the Bureau's 1991 field program.
