This report has been compiled from data gathered in the field in September and October, 1966, and from a detailed survey of the various geologic and mining reports on the Fairbanks lode mining district. A number of people who are familiar with mining in this district have provided some additional information, and their help is gratefully acknowledged.
The map (fig. 1) and table 1 give an essentially complete coverage of the locations and pertinent geologic data for all lode mines and prospects in this district. Analyses of 101 samples, collected on a reconnaissance basis from dump material and exposures that are available around some of the mines and prospects and from several igneous rock bodies that are closely related to the lode deposits, are given in table 2. The analyses provide data for a preliminary evaluation of the geochemical characteristics of the deposits and the rocks to which they are presumably genetically related, and may be helpful background information for future detailed geologic studies and exploration. The metal contents that are shown in table 2 have not been incorporated in table 1.
