Comments on the production information

  • PRODUCTION FIGURES ARE FOR THE ENTIRE DALY PROPERTY, INCLUDING THE DALY SHAFT NO. 2

Workings at the site

  • Type of workings Underground
    Length 93878.4M
    Overall depth 304.8M

Comments on the workings information

  • DALY SHAFT NO. 1 IS 1000 FT DEEP, AS OF 1912, AND WAS THE MAIN DEVELOPMENT ON THE DALY PROPERTY. LEVELS ARE EVENLY SPACED AT 100 FT INTERVALS FOR THE LENGTH OF THE SHAFT. EACH LEVEL IS ABOUT 1500 FT LONG AND FOLLOW THE DALY VEIN. THE 800 FT LEVEL IS THE MOST EXTENSIVE LEVEL AND CONNECTS WITH THE 600 FT LEVEL OF THE ONTARIO MINE. TWO MAIN CROSSCUT TUNNELS, THE FEDERAL AND CENTRAL, ENTER THE HILL NEAR THE DALY SHAFT NO.1 AND STRIKE IN A SOUTHERLY DIRECTION. AN ESTIMATE OF THE TOTAL LENGTH OF THE WORKINGS IS 30000 FT

Comments on development

  • CLAIMS LOCATED BY J.J. DALY IN FEB., 1885 WHO FORMED THE DALY MINING CO. PROPERTY WAS LOCATED FOR THE PURPOSE OF DEVELOPING THE WESTERN EXTENSTION OF THE ONTARIO LODE. PRODUCTION BEGAN IN 1886 AND THE DALY CO. CONTINUED TO SHIP UNTIL 1897. PROPERTY HAS BEEN OPERATED BY LESSEES AND PRODUCED INTERMITTENTLY UNTIL ABOUT 1950. PARK UTAH CONSOLIDATED MINES CO. OWNED A LARGE INTEREST IN THE MINE AND WAS CONSOLIDATED WITH UNITED PARK CITY MINES CO.

General comments

Subject category Comment text
Deposit ORE BODIES LIE EXCLUSIVELY WITHIN FISSURES WHICH ARE A CONTINUATION OF THE ONTARIO VEIN. THE ORE BODIES ARE TABULAR WITH LENTICULAR ENLARGEMENTS. SOME PORTIONS OF THE VEINS ARE ENLARGED UPWARDS, REACHING A MAXIMUM WIDTH OF 140 FT. VEINS USUALLY 20 FT WIDE. ORE SHOOTS REACH THEIR WIDEST EXTENT ABOVE THE 800 FT LEVEL. SIZE OF VEINS AND GRADE OF ORE DECREASES BENEATH THIS POINT. SIX SUB PARALLEL NORTHEAST STRIKING VEINS HAVE BEEN MINED IN A ZONE ABOUT 2800 FT WIDE. FROM NORTH TO SOUTH THE VEINS ARE THE NORTH VEIN, ONTARIO VEIN, DALY VEIN, SOUTH VEIN, MIDDLE VIN, AND DIXIE VEIN. THE DALY VEIN WAS THE GREATEST PRODUCER
