Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Deposit): THE ORE IS SOFT AND PULVERIZED, LIGHT YELLOWISH OR GREYISH IN COLOUR. MINERALIZATION IS COEXTENSIVE WITH WIDESPREAD SILICIFICATION. THE ORE MINERALS LIE WITHIN OR BENEATH JASPEROID MASSES WHICH ROUGHLY PARALLEL THE BEDDING AND FOLLOW THE FISSURES, WHICH GOVERNED THE LOCALIZATION OF ORE TO A GREAT EXTENT. TWO FISSURES ABOUT 20 FT. APART CAN BE FOLLOWED FOR OVER 600 FT. NORTH FROM THE PORTAL, AND VERY RICH ORE IS FOUND ALONG THEM. ANOTHER FISSURE ABOUT 250 WEST OF THESE CAN BE FOLLOWED ALONG ITS STRIKE, ABOUT N10E, FOR OVER 600 FT., CROSSCUTS ABOUT 350 FT. NORTHWEST OF THE GLADSTONE SHAFT INTERSECTED THE GLADSTONE FISSURE, WHICH STRIKES N40E AND DIPS 80 NW. AN INCLINE 175 FT. NORTH OF THE GLADSTONE SHAFT FOLLOWS ONE OF THE INTERMEDIATE FISSURES DOWN TO THE NORTH AND CONNECTS WITH THE WORKINGS AT THE BUFFALO MINE. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT; 3 FIELD OBSERV

Comment (Commodity): THE TENOR OF THE ORE AVERAGED ABOUT 70 OZ. OF SILVER AND $2 IN GOLD TO THE TON, 8 PERCENT LEAD

Comment (Production): THE TOTAL PRODUCTION EXCEEDED $200,000; PRODUCTION FIGURES ARE NOT AVAILABLE.

Comment (Deposit): THE ORE BODIES LIE ALONG THE INTERSECTION OF N-S AND N40E FISSURES AND JUST BELOW OR IN THE LOWER PART OF THE JASPEROID BODIES. THE ORE ZONES ARE CONFINED TO SHALLOW DEPTHS. MINERALIZATION IS LOCALIZED IN ALTERED WALLROCKS

Comment (Workings): TWO SUBPARALLEL ADITS FOR THE TOTAL DEVELOPMENT WORK NOT EXCEEDING 5000 FT.; SHALLOW WINZES AND INCLINES: STOPES ARE COMMONLY 10 OR 15 FT. WIDE AND 3 TO 8 FT. HIGH; ONE SHAFT (GLADSTONE SHAFT); WORKINGS ARE CAVED AND INACCESSIBLE.

Comment (Geology): THE DEPOSIT IS SITUATED IN THE LOWER PART OF THE GREAT BLUE LIMESTONE, BELOW THE LONG TRAIL SHALE MEMBER. WALLROCKS ARE HIGHLY DEFORMED AND ALTERED. LIMESTONES ARE DARK GRAY, CHERTY, DOLOMITIZED, SILICIFIED AND IMPREGNATED WITH CALCITE, QUARTZ AND JASPEROID VEINS. SHALES ARE GREENISH TO GRAY, PULVERIZED, KAOLINITIC, SERICITIC, CARBONACEOUS, CALCAREOUS AND SILICEOUS.
