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 (Commodity): THE COPPER/LODE VEIN OCCURS AT A CONTACT BETWEEN LIMESTONE AND GARNETITE. THE OUTCROP IS A LIMONITE GOSSAN UP TO 80 FEET WIDE AND OVER 600 FEET LONG ON THE SURFACE. METAMORPHIC ROCKS ON THE EAST SIDE OF THE VEIN HAVE BEEN INTRUDED BY QUARTZ MONZONITE; MARBLE FORMS THE FOOTWALL VEIN. TO THE NORTH OF THE COPPER LODE, GYPSUM CROPS OUT IN AN EXPOSED BELT ABOUT 500 FT. WIDE AND 1,500 FEET LONG.

Comment (Deposit): SKARN DEPOSIT LOCATED IN THE TRIASSIC SEPTUM WEST OF MASON VALLEY MINE. ( REFER TO RECORD NO.M035865 ) CONTACT METASOMATIC

Comment (Workings): 8 LEVELS MILES OF UNDERGROUND WORKINGS ON 8 LEVELS.

Comment (Geology): THE FAULT ZONE PARALLELS THE COPPER LOAD LOCALLY BUT TERMINATES TO THE SOUTH PROPERTY SEE (MOORE, J.G.,1969, P.32) SAMPLE 4408 WAS TAKEN FROM DUMPS ASSOCIATED WITH THE MAIN COPPER LOAD AND CONSISTED OF REPLACEMENT ORE AND GOSSAN.

Comment (Development): MINE WAS SHIPPING COPPER IN 1906 . THE LAST GYPSUM WAS SHIPPED IN 1940. THE LOCAL MILL PROCESSED PRIMARY COPPER ORE. THE RAILROAD SHIPPED BOTH COPPER AND GYPSUM FROM LUDWIG TO THOMPSON NEAR WABUSKA; TRANSFERRED TO THE CANDC.

Comment (Deposit): THE NEVADA COPPER BELT RAILROAD (NCB) DEADHEADED AT LUDWIG AND CARRIED BOTH ORES DURING THE LIFE TIME OF THE ROAD TO THOMPSON. IT WAS EITHER PROCESSED OR TRANSFERRED TO THE CANDC. ODDLY ENOUGH, THE NCB WAS A 48-INCH STANDARD GAUGE ROAD WHI THE CANDC WAS A NARROW GAUGE.
