Abstract
In 1983, the Bureau of Mines conducted a literature search and a 10- day field reconnaissance for the Bureau of Land Management to identify mineralized areas in the Iditarod-George planning block in southwestern Alaska. Mineral deposits in the area include (1) lode mercury-antimony, (2) lode gold-silver, (3) lode antimony, (4) lode molybdenum, (5) lode copper-lead-zinc, (6) gemstone (?), (7) placer gold, (8) placer mercury, (9) placer tungsten, (10) coal, (11) oil and gas, and (12) sand and gravel. A geothermally active area was noted. During the literature search, 7 lode mines, 15 placer mines, 10 lode prospects, 9 lode occurrences, 10 placer prospects, 12 placer occurrences, 2 coal prospects, 1 gemstone (?) occurrence, and 1 sand and gravel pit were identified. In addition to the literature data, stream sediment and rock samples were taken to identify the presence of minerals and elements and to delineate the mineralized areas. Fourteen areas contain anomalous concentrations of several elements: 12 areas contain anomalous concentrations of 1 element, 2 contain coal, 2 have potential for oil and gas, and 1 is geothermally active. All stream valleys contain sand and gravel. Metals of possible economic interest found in the samples include antimony, chromium, cobalt, copper, gold, lead, manganese, mercury, molybdenum, nickel, tin, titanium, and tungsten. Placer deposits contain gold, mercury, and tungsten. Deposit grades and reserves were not established.
