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): MINERALIZATION LOCALIZED NEAR EAST MARGIN OF COLLAPSED SUMMITVILLE CALDERA WHERE CORNWALL FAULT RING FRACTURE TRUNCATES OLDER POST-PLATORO-COLLAPSE CORNWALL RESURGENT BLOCK, DISPLACING UPPER SUMMITVILLE ANDESITE OF SUMMITVILLE CALDERA ON NW AGAINST LA JARA CANYON MEMBER OF THE PLATORO CALDERA ON SE. JUST NORTH OF ALAMOSA RIVER AND JASPER IS INFERRED INTERSECTION OF OLDER CALIFORNIA GULCH FAULT (EAST BOUNDARY OF CORNWALL RESURGENT BLOCK) AND YOUNGER CORNWALL FAULT (SUMMITVILLE RING FRACTURE). JASPER ANDESITE PORPHYRY STOCK IS POST-SUMMITVILLE-COLLAPSE CALDERA-MARGIN INTRUSIVE. SMALL MONZONITE PORPHYRY STOCK SITUATED ON CORNWALL FAULT JUST SOUTH OF RIVER APPARENTLY LOCALIZED MINERALIZATION AND ALTERATION AT MISER AND GUADALOUPE MINES. PRINCIPAL NW-SE VEIN TRENDS FROM MISER AREA APPARENTLY EXTEND INTO PERRY PROPERTY. WOOLF (1914) REPORTS THREE FAULTS IN TUNNEL--TWO AT N 35 W, 50 SW AND THIRD AT N 60 W, 50 SW, REFLECTING FRACTURE TRENDS ASSOCIATED EITHER WITH CORNWALL BLOCK RESURGENCE OR

Comment (Deposit): WITH SUMMITVILLE CALDERA COLLAPSE.

Comment (Workings): 225-FT CROSSCUT TUNNEL DRIVEN GENERALLY SW CONNECTING WITH 150-FT INCLINED SHAFT

Comment (Location): ON LOWER NE SLOPE OF CORNWALL MTN SOUTH OF ALAMOSA RIVER 0.7 MILES SW OF JASPER. ; INFO FROM LAND.ST :1977

Comment (Development): PERRY MINE WAS FIRST TO PRODUCE IN JASPER DISTRICT. INTERESTING FEATURE OF MINE WAS ORE HAULAGE DOWN THE HILLSIDE VIA WOODEN RAILWAY INCLINED AT ABOUT 32 DEG. ORE CAR JUMPED THE TRACK ON SECOND TRIP, AND STRUCTURE WAS NOT USED AGAIN.
