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): RICH SILVER ORES REPORTEDLY STRUCK IN SHAFT. THE DIXIE VEIN IS LOCATED WITHIN THE GENERAL VICINITY OF THE SHAFT AND IS PROBABLY WHAT WAS EXPLORED BY THESE WORKINGS. SHAFT AND ASSOCIATED TUNNELS CONNECT WITH THE DALY MINE WORKINGS

Comment (Workings): MAZEPAH SHAFT CONNECTS WITH TUNNELS OF THE DALY MINE. DEPTH OF SHAFT PROBABLY LESS THAN 1200 FT

Comment (Geology): NORTH-SOUTH FAULT JUXTAPOSES THE PARK CITY FORMATION AND WEBER QUARTZITE NEAR THE SHAFT. MINERALIZATION, HOWEVER, IS RELATED TO NORTHEAST SET OF FISSURES AND FAULTS

Comment (Development): MAZEPAH SHAFT IS PART OF THE DALY MINE. MAZEPAH SHAFT WAS SUNK ABOUT 1911 TO EXPLORE WESTERN PART OF PROPERTY NOT ON THE DALY - ONTARIO FISSURE SYSTEM. THIS EXPLORATION WAS UNDERTAKEN AFTER MAIN DALY ORES HAD BEEN DEPLETED AND RICH ORES WERE FOUND ON THE ADJACENT ONTARIO PROPERTY

Comment (Location): INFO FROM LAND.ST :1983

Comment (Commodity): RICH SILVER ORE STRUCK BY SHAFT

Comment (Production): PRODUCTION FIGURES ARE REPORTED WITH FIGURES FOR DALY MINE, SEPARATE RECORDS NOT KEPT
