Capsule Geology

The Silver Band occurrence is located at 2057 metres elevation, near the headwaters of Aylwin Creek in Eight Mile Basin. Silverton, British Columbia is located 8.25 kilometres to the north.

Workings on the Silver Band occurrence consist of several opencuts and an adit. In 1935, the property was owned by P.J. Keogan.

The Silver Band occurrence is hosted in potassium feldspar porphyritic granite of the Middle Jurassic Nelson intrusions, adjacent to an outlier of Lower Jurassic Rossland Group metavolcanics and Early Jurassic subvolcanic equivalents. Lithologies comprising the Rossland Group at the Silver Nugget occurrence include pyritic quartzite, augite porphyry, greenstone and argillite. These rocks have been tentatively correlated with the Elise Formation. Early Jurassic subvolcanic equivalents include quartz latite porphyry and feldspar porphyry. For a more detailed description of the geology of this outlier refer to the Willa occurrence (082FNW071).

The occurrence is a 1.5-metre wide shear zone crosscutting coarse grained porphyritic granite of the Nelson intrusions. The zone strikes 065 degrees. Galena and sphalerite in a brecciated quartz-calcite-siderite gangue comprises mineralization.

A little high grade silver ore is reported to have been shipped from the property prior to 1935 but no official records exist (Geological Survey of Canada Memoir 184, page 122). Zinc values are reported to have exceeded lead (Geological Survey of Canada Memoir 308, page 119).
