Comments

Comment (Workings): MINE WORKINGS CONSIST OF 168 FT. TWO COMPARTMENT SHAFT, A 100 FT. SOUTH-TRENDING DRIFT AND A 50 FT. WEST-TRENDING CROSSCUT, AND A 95 FT ADIT

Comment (Geology): MINERALIZATION IS ALONG CREST OF A TIGHTLY FOLDED ASYMMETRICAL ANTICLINE. THE MINERALIZATION IS GREATEST WHERE A FAULT CUTS THE CREST. LARGEST MINERALIZED POD CONTAINED 300 POUNDS CINNABAR.

Comment (Deposit): ORE OCCURS AS PODS AND DISSEMINATIONS IN FAULT BRECCIA. A MODEL HAS NOT YET BEEN PUBLISHED FOR THIS TYPE OF DEPOSIT

Comment (Location): LOCATION APPEARS TO BE IS QUESTION. IT MAY BE IN SEC. 8 OR IN SEC. 9 ON SMALL TERRACE ON SOUTH BANK OF GREEN RIVER

Comment (Development): ARSENIC CONTAMINATES THE MERCURY; ORE CONCENTRATIONS DISTRIBUTED ERRATICALLY.

Comment (Deposit): Discovery Year: LATE 1800'S
