Small amount of copper ore
Alteration: Silicification
Deposit: Badly folded and fractured phyllite and slate cut by n40 W shear zone which provided a conduit for cu-bearing solutions exposed in a 50 x 150 ft open pit. Slickensides are common leaving a thick, shiny veneer of fault gouge on many of the sediments. Numerous springs along parallel faults. Developed by 2 adits ; info.src : 1 pub lit; 2 unpub rept; 3 field observ
Deposit type: Low-sulfide Au-quartz vein
Development: 2 adits
Geology: Anomalous radioactivity varies directly with secondary copper minerals. Chrysocolla, azurite, chalcocite, malachite, limonite, quartz, and torbernite are present along a 3-10 ft. Wide shear zone between silicified limestone and a diorite.
Ore(s): 3-10 Ft. Wide Shear Zone Between Silicified Limestone And A Diorite.
