Mineral Investigations in the Ketchikan Mining District,, Alaska, 1990: Southern Prince of Wales Island and Vicinity. Preliminary Sample Location Maps and Descriptions
The U.S. Bureau of Mines began a five-year million study of the 7.0 acre Ketchikan Mining District during 1990. This study is part of the Bureau's ongoing statewide mining district evaluation program. The study area was subdivided and then prioritized by mineral potential into work units. Bureau field work in 1990 focused on the southern portion of Prince of Wales Island and vicinity. Extensive mineral resources have been mined historically in the area and are presently being evaluated by private industry. Information in this report is based on an extensive literature search and Bureau field work.
