NBMG Sample Site 1434 Northern Most Shaft
Structure: Prominent Fault Exposed In A Shaft At Northern End Of Workings, Trending N60w, Dip Ne
Alteration: Strong Hydrothermal Alteration In Vicinity Of Fault
Deposit: Workings follow nne-trending fault contact between camb. Lyndon limestone and undifferenitated cambran dolomite, dumps consist of silicified carbonate breccia cemented with calcite, siderite, and hematite-stained silica.sulfides occuring in breccia are oxidized with a fe W fresh grains, and consist of fine-grained pyrite, galena, sphalerite (?), which have altered to Fe oxides, malachite, chrysocolla, limonite, and possibly some minor smithsonite. Late-stage silica coats surfaces and drusy quartz fills vugs and coats fracture surfaces. Fault in shaft at N end of workings where a siliceous, iron oxide-stained rib outcrops, with siliceouds, rib parallel to main rib. Rocks in vicinity of fault zone are hydrothermally altered and have cooked appearance. Abundant gossan occurs near, and associated with the fault.
Deposit type: Polymetallic replacement
Development: Reported to be hoisting good ore in 1909
Rock formation(s): Lyndon Limestone;Davidson Dolomite (Local Name)
Ore(s): Fault Contact Between Lyndon Limestone And Dolomite
