Placer Gold Sampling in and near the Chugach National Forest, Alaska

摘要

The Bureau of Mines and U.S. Geological Survey completed a 4-yr (1972-82) mineral appraisal of the Chugach National Forest (CNF), AK. the report summarizes the Bureau's placer gold studies in the CNF. Placer mining from the mid-1890's through 1982 produced an estimated 133,800 oz of gold, of which two-thirds was produced prior to 1920. As much as 6,800 oz of placer gold was produced from 1979 to 1982. Most production came from Crow, Canyon, and Resurrection Creeks. Subsequent investigations in drainages with anomalous placer sample values also identified previously unknown lode mineralization.
