Comments

Comment (Deposit): GOLD IS NOT VISIBLE IN THE ORES, AND IS CONCENTRATED IN THE CARBON-RICH PORTIONS OF THE ALTERED ZONES. THE ORE IS SOFT AND PULVERIZED, LIGHT YELLOWISH OR GRAYISH IN COLOR. THE ORES IF FORMED BY THE IMPREGNATION AND REPLACEMENT OF THE WALLROCKS; AND THE FISSURE FILLINGS ARE NEGLIGIBLE. NEVERTHELES THESE FISSURES WERE OF FUNDAMENTAL IMPORTANCE IN LOCALIZING THE DEPOSITS. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT; 3 FIELD OBSERV

Comment (Location): INFO FROM LAND.ST :(1977)

Comment (Production): PRODUCTION FIGURES ORE NOT AVAILABLE; ON AN AVERAGE HALF AN OUNCE OF GOLD IS RECOVERED FROM ONE TON OF ORE

Comment (Deposit): MINERALIZATION IS LOCALIZED IN ALTERED ZONES. THE OXIDIZED ORE IS LIGHT COLOURED AND MORE FRIABLE THAN THE UNOXIDIZED (ABSE) ORE. IT LACKS SULFIDES AND CONTAINS SULFATES INCLUDING GYPSUM, SCORODITE, AND MELENTERITE. THE ORE ZONE IS GENERALLY 10 FT THICK.

Comment (Workings): TWO ADITS AND TWO VERTICAL SHAFTS (NAMELY, MABEL SHAFT OR NORTH SHAFT; AND GRASSHOPPER SHAFT OR SOUTH SHAFT); ALL CAVED AND INACCESSIBLE; ONE PIT OF 220X120X50FT SIZE.

Comment (Geology): WALLROCKS ARE SHEARED AND ALTERED. LIMESTONES ARE DARK GRAY, CHERTY, DOLOMITIZED, SILICIFIED, AND IMPREGNATED WITH CALCITE AND QUARTZ VEINS. SHALES ARE GREENISH TO BLACK, CARBONACEOUS, SILICEOUS, SERICITIC, KAOLIMITIC, AND HIGHLY EXAMPLED. EFFECTS OF LIMONITIZATION ARE FOUND ON HOSTROCKS. ORE MINERALS ARE INTIMATELY ASSOCIATED WITH JASPEROID, AND QUARTZ VEINS.
