Introduction

This report was prepared as a supplement to a 1976 report which sum- marized data on mineral occurrences in the Wiseman quadrangle, Alaska (Cobb, E. H., 1976, Summary of references to mineral occurrences (other than mineral fuels and construction materials) in the Chandalar and Wise- man quadrangles, Alaska: U.S. Geological Survey Open-File Report 76-340, 205 p.). As a result of suggestions from users of the series of which the 1976 report is a part, this supplement is released in two parts: Part A, which presents summaries of data to January 1, 1981, and Part B, which consists of reference lists for each occurrence.

In Part A data from most reports released between the cut-off date (January 1, 1975) for the original report and January 1, 1981 have been incorporated in rewritten or new summaries where appropriate. For each occurrence described in Part A the name, U.S. Bureau of Mines mining district, reference that has the occurrence plotted on a map on a scale of 1:250,000, list of mineral commodities, and location data are in the same format as in the 1976 report. Also included is a list of synonyms, owners, operators, and claim names.

In both parts citations are in standard bibliographic format with the exception that references to reports and maps in numbered publication series alsc show, in parentheses, an abbreviation for the report or map series and the number of the report or map. Abbreviations used are:

B U.S. Geological Survey Bulletin BMB U.S. Bureau of Mines Bulletin C U.S. Geological Survey Circular GC Alaska Division of Geological Survey Geochemical

Report I C U.S. Bureau of Mines Information Circular OF U.S. Geological Survey Open-File Report MF U.S. Geological Survey Miscellaneous Field Studies

Map P U.S. Geological Survey Professional Paper R I U.S. Bureau of Mines Report of Investigations TDM Alaska Territorial Department of Mines Pamphlet USBM OF U.S. Bureau of Mines Open-File Report

In Part B citations to the principal references used in preparing summaries in Part A are preceded by an asterisk. The form of citation used in the reference list for each occurrence is considered sufficient identification for each numbered report or map to be found easily in most libraries. Complete references to reports without identifying numbers are listed at the end of Part B.

The following two U.S. Bureau of Mines Open-File Reports were not used in preparing this supplement because descriptions of most occurrences are not sufficiently detailed to allow evaluation of deposits. In many descriptions it is not possible to determine if a potentially valuable mineral was identified or if the report is based solely on an analysis of a sample collected during a geochemical survey. Most specific data are also in other reports, such as Grybeck, 1977 (OF 77-166C).

About $500 worth of gold (less than 25 oz) was mined in 1901. Work in 1937 probably was not successful. Includes references to: (Kelly's Gulch), (Kelly's Mistake Cr.).

Wiseman (9.7-10.0, 8.4-8.6) 67O29'~, 151°31'-151033'~

Bedrock is various kinds of schist cut by at least one greenstone dike; many quartz stringers near head of creek. Bedrock at head of delta into Wild Lake is 60-95 ft deep; gravel in stream bed above delta is only 3 ft thick. Placer concentrates contain gold, Large pieces of stibnite, scheel- ite, native copper and bismuth, hematite, pyrite, and a little magnetite. A sample of vein quartz contained a little chalcopyrite and tourmaline. Gold, both coarse and very fine, was mined intermittently from 1904 until at least as recently as 1938. Recorded production as of 1937 was worth about $26,000, which is probably many rhousand dollars too low.
