General comments

Subject category Comment text
Deposit "probably close to the Koch manganese and feldspar claims in T32N, R79W, 11 mi. south of Casper. A seam of black material wihch carries gold and silver cuts granite. Gold ans siver values have been found in a dolerite dike in the granite." (Bull. 50, p. 92). But Bull. 50 does not list this deposit in the section on silver, therefore silver is not listed in this record as a primary commodity.
Deposit A SEAM OF BLACK MATERIAL CARRIES AU AND AG.
