Mining district

District name Park City District

Land status

Ownership category Private

Ownership information

  • Type Owner
    Owner United Park City Mines Co.

Comments on the production information

  • PRODUCTION FIGURES EITHER UNREPORTED OR REPORTED WITH DALY WEST MINE. PROBABLY INCLUDED WITH DALY WEST PRODUCTION AFTER 1901

Workings at the site

  • Type of workings Surface/Underground
    Length 1828.8M
    Overall depth 182.88M

Comments on the workings information

  • THE QUINCY SHAFT HAS LEVELS AT 100, 200, 300 AND 400 FT. FROM THE 400 FT LEVEL A MAIN INCLINE, WITH LEVELS AT REGULAR INTERVALS, CONNECTS WITH THE UPPER WORKINGS OF THE DALY WEST MINE. THE 200 FT LEVEL CONNECTS WITH THE 300 FT LEVEL OF THE LITTLE BELL MINE. SEPARATION OF THE WORKINGS OF THE DALY WEST AND QUINCY MINES IS DIFFICULT BECAUSE OF THEIR EARLY CONSOLIDATION. TOTAL LENGTH OF WORKINGS ESTIMATED AT 6,000 FT

Comments on development

  • CLAIMS WERE PROBABLY LOCATED IN THE LATE 1880'S OR EARLY 1890'S. CLAIMS LEASED TO COL. W.M. FERRY UNDER THE NAME OF PUTNAM MINING CO., IN 1898 OR 1899 THE QUINCY MINING COMPANY WAS FORMED AND ACTIVE EXPLORATION BEGAN. ORE HIT AT 110 FT LEVEL OF SHAFT AND PRODUCTION BEGAN IN 1901, REACHING 725,000 DOLLARS. IN 1902 IT WAS THE LARGEST PRODUCER OF THE DISTRICT. PROPERTY CONSOLIDATED WITH DALY WEST MINE IN 1902, AS A RESULT OF LAW SUITS CONCERNING THE APEX LAW. QUINCY PLANT WAS CLOSED IN 1904 AND WAS SINCE WORKED THROUGH THE DALY WEST TUNNELS. PROPERTY LATER CONSOLIDATED WITH PARK UTAH MINING CO. IN 1920 AND WITH UNITED PARK CITY MINES IN 1753 PRODUCTION HAS CONTINUED ON A SMALL, INTERMITTENT BASIS THROUGH THE 1960'S

Subject category Comment text
Deposit BOTH BEDDED REPLACEMENT AND VEIN ORE BODIES OCCUR. BEDDED DEPOSITS ARE STRATA BOUND, TABULAR REPLACEMENT ZONES IN THE PARK CITY, FORMATION, GENERALLY LYING WITHIN A FEW 10'S OF FEET FROM FISSURES OR FRACTURE ZONES AND HAVING THICKNESSES OF 4 TO 5 FEET. THE HORIZON IN WHICH REPLACEMENT DEPOSITS OCCUR IS 40 FT ABOVE THE TOP OF THE WEBER QUARTZITE AND IS COMPRISED OF A PURE BLUE LIMESTONE. VEIN DEPOSITS ARE LOCATED WITHIN NORTHEAST STRIKING FAULT ZONES DIPPING MODERATELY TO THE NORTHWEST. THESE FAULT ZONES LIE SOUTH OF THE DALY-ONTARIO FISSURE SYSTEM BUT ARE SIMILAR IN CHARACTER. THESE SAME FAULT ZONES ALSO CONTROL THE DISTRIBUTION OF REPLACEMENT ORE BODIES. REPLACEMENT ORE IS MORE ABUNDANT THAN VEIN ORE. THE REPLACEMENT HORIZON OCCURS AT 110 FT IN THE QUINCY SHAFT AND DIPS 20 DEGREES TO THE NORTHWEST
