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 (Development): PRIOR TO CONSOLIDATION WITH PARK UTAH CONSOLIDATED MINES IN THE 1920'S, THE DALY-JUDGE PROPERTY COMPRISED 138 PATENTED CLAIMS COVERING AN AREA 4000 FT BY 15000 FT, AND INCLUDED THE OLD UTAH MINE, WHITE PINE MINE, ANCHOR MINE, AND THE JONES CLAIMS. ORE WAS STRUCK IN A 100 FT SHAFT ON THE WHITE PINE MINE AS EARLY AS 1878 WITH PRODUCTION STARTING IN 1881. ANCHOR SHAFT STARTED IN 1885. IN 1888 A DRAIN TUNNEL, 6600 FT LONG WITH A PORTAL IN EMPIRE CANYON, WAS STARTED. DRAIN TUNNEL COMPLETED BY 1890 AND MINING RESUMED. ACTIVE MINING CONTINUED UNTIL THE 1920'S. INTERMITTENT MINING UNTIL 1950 OR 1951. CURRENTLY PART OF UNITED PARK CITY MINES CO. HOLDINGS

Comment (Deposit): Discovery Year: LATE 1870'S

Comment (Location): LOCATION GIVEN IS FOR THE MAIN OPENING OF THE DALY-JUDGE MINE, OTHERWISE KNOWN AS THE ANCHOR SHAFT ; INFO FROM LAND.ST :1983

Comment (Production): COMBINED PRODUCTION FOR THE DALY WEST AND DALY JUDGE MINES WAS FROM 1899-1951, 4265346 TONS OF ORE CONTAINING 79051 OZ AU, 51264289 OZ AG, 744384966 LBS PB, 401616365 LBS ZN, AND 31831461 LBS CU

Comment (Deposit): BOTH BEDDED AND REPLACEMENT ORES PRESENT. REPLACEMENT ORES LOCATED SOUTHEAST OF THE DALY-ONTARIO FAULT ZONE FOR A DISTANCE OF UP TO 1500 FT. REPLACED HORIZON IS THE JENNY BED, LOCATED ABOUT 100 FT ABOVE THE TOP OF THE WEBER QUARTITE, WITHIN THE PARK CITY FORMATION. ANOTHER REPLACEMENT HORIZON WAS DISCOVERED IN 1923 NEAR THE VERY TOP OF THE PARK CITY FORMATION. INDIVIDUAL REPLACEMENT ORE BODIES ARE STRATABOUND WITH BEDDING DIPPING 22 DEGREES TO THE NORTH. EACH ORE BODY IS WITHIN 200 FEET OF 4 MAJOR FISSURES STRIKING NORTHEAST. FISSURES ARE NAMED, FROM NORTH TO SOUTH, THE DALY WEST-DALY-JUDGE, ROLL, MIDDLE, AND BACK VEINS. FISSURE DEPOSITS ARE COINCIDENT WITH THE FOUR VEINS MENTIONED ABOVE. REPLACEMENT ORES VOLUMETRICALLY MORE IMPORTANT

Comment (Workings): ANCHOR SHAFT IS 1600 FT DEEP. CROSSCUT LEVELS AT 500, 700, 1200, 1400, 1500, AND 1600 FT WITH A DISTANCE OF 2100 FT EACH. LEVELS AT 500, 700, 1200, 1300, 1400, AND 1500 FT ARE 1000 FT LONG EACH. LEVELS AT 1200 AND 1400 FT ARE MORE THAN 3000 FT LONG. AREA OF UNDERGROUND WORKINGS IS 2100 BY 3000 FT. DRAIN TUNNEL IS 6600 FT LONG ON THE 1200 FT LEVEL. NEARBY WORKINGS INCLUDE SIX PROSPECT ADITS AND TWO PROSPECT PITS. FIGURES ABOVE WERE CURRENT IN 1912

Comment (Geology): GREAT THICKNESS OF LIMESTONE OCCURS ALONG DALY-ONTARIO FAULT ZONE DUE TO NEAR JUXTAPOSITION OF PARK CITY FORMATION AND THAYNES FORMATION. GENTLE SYNCLINE IN FOOTWALL.
