Other/historical names associated with this locality:
NBMG Sample Site 2355
Alteration: Strong Silicification
Deposit: Pyrite, galena and sphalerite occur As massive replacements of wallrock and in white massive to drusy quartz. No obvious veins are noted; the quartz apparently occurs As pods. The wallrocks away from the mineralized zone are interbeded gray shale and limestone. In the open pit, the rocks are hard dense silicified hornfels with a high sulfide mineral content. One piece of ore, included in sample 2355 is entirely solid galena and sphalerite. Pyrite occurs As streaks and irregular patches in dense silica-rich rock. White quartz vein matter contains scattered galena and pyrrhotite. A dike of altered granodiorite porphyry was noted in the portal of an adit about 400 m north of the sampled open pit. No other igneous rocks were noted. The silicified and sulfide-rich rocks at this property resemble those at the hillside or adelaide mines, except that there are no obvious copper minerals here.
Deposit type: Polymetallic replacement
Development: No activity here, but exxon co. Has recently drilled on claims to the SE about 1.2 km.
Rock formation(s): Preble
