Comments

Comment (Workings): WORKINGS ARE CAVED AND INACCESSIBLE. THEY ARE DEVELOPED ON THE UPPER LEVELS BY AN INCLINED SHAFT AND ON THE LOWER LEVELS BY A VERTICAL SHAFT WHICH CUT THE ORE BED AT 1,600 FEET ON THE DIP; SEVERAL SMALL PITS AND TRENCHES.

Comment (Location): INFO FROM LAND.ST :(19(()

Comment (Production): THE TOTAL PRODUCTION IS BELIEVED TO HAVE BEEN ABOUT $219,646 IN GOLD.

Comment (Deposit): THE ORE DEPOSIT IS IN THE GREAT BLUE LIMESTONES BENEATH THE LONG TRAIL SHALE MEMBER.

Comment (Geology): THE OXIDIZED ORE IS LIGHT COLORED AND MORE FRIABLE THAN THE MOXIDIZED (BASE) ORE. IT LACKS SULFIDES AND CONTAINS SULFATES, INCLUDING GYPSUM, JAROSITE, SCORODITE AND MELANTERITE.

Comment (Deposit): GOLD IS NOT VISIBLE IN THE ORES; AND IS CONCENTRATED IN CARBON-RICH PORTIONS OF THE ALTERED ZONES. MANY LIMESTONE BEDS ARE SILICIFIED TO JASPEROID. SHALES ARE LESS ALTERED, AND SHOW SOME EFFECT OF SERICITIZATION. THE ORE SHOOTS FOLLOW APPROXIMATELY THE INTERSECTION OF THE FISSURES WITH THE ORE BEDS ; INFO.SRC : 1 PUB LIT; 3 FIELD OBSERV
