Other/historical names associated with this locality:
New Freiberg Project Part
Structure: Thrust Faults Faults, Fractures
Alteration: Bleaching, Silicification
Deposit: 2 prominent ribs of jasperoid outcrop adjacent to shafts. Outcrops are fractured, brecciated and contain iron oxide box works and gossany vugs. A few oxidized pyrite "ghosts" noted in outcrop. Main jasperoid outcrop. Main jasperoid outcrop strikes n10-20e dips 70-75 nw. Jasperoid rubble indicates that it extends north several 10's of ft. Jasperoid body shows fracture planes developed parallel to the trend of the outcrop. The body obviously marks the trace of a silicified, mineralized (?) fault zone within the limestone. An altered dike intrudes the jasperoid zone nearby to the south. Sample 1761 consists of calcite-cemented limestone breccia with gossany(fe and mn) portions and containing pyrite, cerussite, and malachite as lenses, clots and fracture coatings. Coarse calcite vein on dump contains a fair amount of partially oxidized pyrite, also. The rocks are heavy and may contain barite. Scattered green minerals (coatings) are possibly anglesite or scorodite. Sample 1762 is from the jasperoid outcrop adjacent to main shaft. It is heavily stained by Fe and Mn oxides.
Development: No activity at time of examination in 1983, but area was staked and had been drilled in past 3-5 years
Rock formation(s): Pogonip Group
Ore(s): Fault Zone
