| Jeep Mine | |
This mine was worked by San Antonio Gold Mines Limited from 1948 to 1950 and ore was trucked to the mill at Bissett 14.5 km away. The shaft was 180m deep. Several lenticular quartz veins, rarely more than 0.5m thickness, occupy parallel shear zones in mafic to intermediate plutonic host rocks. These veins carry pyrite mineralization with subsidiary amounts of pyrrhotite and arsenopyrite, and minor chalcopyrite, a little scheelite is present. Apart from quartz, gangue minerals are scarce. Silicification is perhaps the most prevalent wall rock alteration. Sheared wall rock shows carbonate and chlorite alteration with some pyrite. Gold is associated with arsenopyrite and also occurs in the native form. Although small in terms of tonnage - about 25 tons/day average - this mine was quite profitable thanks to a grade which averaged 0.78 oz./ton over the life of the operation. Tons Milled - 17,562 tons Gold Recovered - 13,629 oz. Silver Recovered - na Average Grade - 0.77 oz./ton Years Worked - 1948-50
