The U.S. Bureau of Mines is conducting a 4-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 U.S. Geological Survey conducted preliminary regional geologic mapping and regional geochemical sampling while the Bureau conducted site-specific examinations and detailed sampling of identified mineral occurrences. The study includes the location and identification of deposits of barium, chromium, copper, lead, manganese, silver, zinc, and other mineralization. Nineteen mineral occurrences, including 12 occurrences that were previously unreported, were identified, examined, and sampled. Anomalously high concentrations of antimony, arsenic, barium, cadmium, chromium, manganese, nickel, strontium, and titanium were found in several drainages. Detailed geologic mapping and rock and soil sampling were conducted at Drenchwater Creek, Kady, Kivliktort Mountain East, Kivliktort Mountain West, Koiyaktot Mountain East, Koiyaktot Mountain West, and Story Creek.
