The Petersburg project region covers about 16,300 km and includes all of the Petersburg, about one-third of the Port Alexander, a small part of the Sitka, and about one-tenth of the Sumdum l:250,000-scale quadrangles. The region is located in south-central southeastern Alaska and includes parts of the (from west to east) Chatham Trough, Prince of Wales Mountains, Kupreanof Lowland, Coastal Foothills, and Boundary Ranges physiographic divisions of Wahrhaftig (1965). Two towns, Petersburg and Wrangell, and two villages, Kake and Point Baker, are in the region. The region contains three mines and a wide variety of metallic mineral occurrences (Grybeck and others, 1984). One mine produced barite, one gold, and the other garnet. The region has long attracted the attention of prospectors and mineral exploration companies. This map and text report the results of a mineralresource-assessment study done during the period 1978 to 1982. The resource terminology used here is that of the U.S. Bureau of Mines and U.S. Geological Survey (1980; see Appendix A). As described below, a multidisciplinary team working in the field and office identified five mineral-resource tracts containing identified resources and other attributes that indicate a high probability for the occurrence of economic mineral deposits. The team also identified eight other tracts that have quantified undiscovered resources and other attributes that indicate a lesser probability for economic deposits. Unqualified undiscovered resources are believed to be present in 15 other tracts; three tracts have only geophysical anomalies that may have mineral-resource significance. Altogether, 31 tracts are shown on the map and described below. Several of the tracts overlap because they are defined by separate criteria or because different types of deposits are interpreted to be present.

“…Abundant cuprite, azurite, malachite, goethite, and chrysocolla are found on the mine dumps. Wedow (1953) and West (1954) investigated the Konechney deposit because of its anomalous uranium content, and analyses of our samples indicate up to 106 pprn uranium (table 3, 85BT184A). The zone was traced for 150 m (470 ft) along strike before it disappeared under valley talus and vegetation on its northwest limit.…”

An important factor in any rebirth of metal mining in Alaska will be a thorough appraisal of the metalliferous lodes already known in the State. Any such appraisal probably will depend, a t least in part, on an inventory of these 1 deposits and a knowledge of their geology. This report summarizes from repoAs of Federal and State agencies published before August 31, 1965, the geology of Alaska's metal-bearing lodes, including their structural or stratigraphic control, host rock, mode of origin, kinds of .Q minerals, grade, past production, and extent of exploration. I n addition, the lists of mineral occurrences that accompany the 35 mineral-deposit location maps constitute an inventory of the State's known lodes. A total of 692 localities where m&alliferous deposits have been found are shown on the maps. The localities include 1,739 mines, prospects, and reported occurrences, of which 821 are described individually or otherwise cited in the text. ORGANIZATION AND METHOD OF PRESENTATION This report is arranged by mining regions and mining districts, geographical subdivisions whose boundaries, defined by the U.S. Bureau of Mines (Ransome and Kerns, 1954), mostly follow major drainage divides (pl. 1). We adopted this classification, which is largely independent of geology, chiefly for convenience and simplicity, but it also minimizes the tendency to sort our data by metallogenic provinces or to speculate on regional geologic controls that have governed the formation of certain mineral deposits-subjects that are beyond the scope of this report. The 14 mining regions and the 67 districts included in them are arranged in alphabetical order and are accompanied by maps showing the locations of all known mines, prospects, ,and reported mineral occurrences. To conserve space, adjoining districts that are small or contain only a few lode mineral localities, are combined on single maps. Each locality has been given a number that corresponds to a citation in the text. The descriptions of the lode deposits of each mining region or each district (in the case of the Yukon River region) are prefaced by brief summaries of the physiography and 4 METALLIFEROUS LODE DEPOSITS OF ALASKA large enough to appear on the map, but in some cases this was not possible. All geographic names cited in this report, however, do appear on I; 250,000-scale (1 inch=approx. 4 miles) or larger scale topographic maps published by the U.S. Geological Survey; the reader who is interested in locating a deposit or geologic feature precisely is urged to consult the appropriate topographic map.
