The Mt. Schwatka Region, located about 75 miles north of Fairbanks, was investigated to provide data on mineral potential for the Bureau of Land Management. The investigations were undertaken in early 1978 as a result of a tentative geological correlation of this area to the Selwyn Basin lead-zinc districts, eastern Alaska, and the Yukon Territory. Correlation is based on a reconstruction of approximately 450 km of right-lateral Mesozoic movement along the Tintina fault system. Prior to the investigation, there was no recorded information concerning mineralization or mining-claim locations. Occurrences of lead and zinc were found in an area underlain by early to mid-Paleozoic marine sediments and volcanics. There appears to be an affinity between these occurrences and the succession of units known as the Fossil Creek volcanics-ordovicians (silurian?). In one case, volcanogenic zinc was found in a cherty, intermediate, tuffaceous breccia. Lead and zinc values also appear associated with the upper stratigraphic levels of the volcanics and controlled by the unconformity and/or fault contact with the overlying tolovana limestone. Manganese mineralization was identified in undifferentiated Paleozoic (Permian?) cherts and Mafic volcanics to the west. There also appears to be a potential for asbestos deposits.
