Report: Nora Darling LC004489 The Nora Darling (also called the 7-11) is located in the SEĽ section 17, T.11N., R.7W. Workings include three adits (two caved, one partially caved but still open with stulls and daylighted with a hazardous vertical hole remaining). There is also a vertical shaft and an inclined shaft, both partially open. Access to this site good to within ˝-mile then access is by walking. No mine discharges and very few sulfides are present. The buildings here have all totally collapsed. Ore appears to have been brecciated limestone (Devonian Jefferson dolomite according to Loen, 1990) with an associated Tertiary andesite dike. Loen (1990) describes this occurrence as a replacement deposit. A sample (POND-1) included limestone breccia cemented with orange-stained silica, silicified orange-red microcrystalline quartz, some ocherous-punky limonite, secondary copper minerals, MnOx, FeOx, and drusy, gray quartz/calcite veins. POND-1 assayed 0.131 opt Au, 0.088 opt Ag, 0.98% Cu, 0.002% Pb and 0.01% Zn.
