Report: Banner Very little information on the Banner exists in the literature, and it it located in an area of glacial moraine and has been reclaimed, so geology is concealed. A USFS report dated 1920 (unpublished information, MBMG files) states that the mine then included a 250 foot inclined shaft with 600 feet of drifts on two levels. Bannister and others (1983) uncovered some information. They stated that the mine was worked from 1921 to 1923 and from 1934 to 1936, producing 1979 oz of gold, 5896 oz of silver, and 20,935 lbs of copper. The size of the dump and tailings indicate several thousand feet of workings are present. Vein material containing quartz, 5-10% pyrite, a trace of galena, and a trace of chalcopyrite is present; a select sample (JGBA-2) ran .158 oz/ton gold, 1.76 oz/ton silver, .18% copper, .12% lead, and .060% zinc. Host rock appears to be Mount Shields(?) quartzite, and some on the dump contains quartz and 1-2% disseminated pyrite. This altered wallrock (JGBA-1) also had some metal value--.014 oz/ton gold, .28 oz/ton silver, .015% copper, .002% lead, and .014% zinc. The nearest outcrop of igneous rock is Cretaceous(?) diorite at the M & T Mine 1.5 miles north. The vein is supposedly 4-9 feet thick with a N25W 30SW attitude (Bannister, 1983), so it may occupy a shear created by thrust faulting. The nearby Old Dominion Mine contains similar structural controls, but the vein mineralogy is vastly different (Lofholm, 1985). The mine dumps of 75% unaltered and 25% altered quartzite are perched on the banks of the Middle Fork of Rock Creek on private land. There is also a considerable volume of tailings present. These were allowed to run into a kettle within the glacial moraine, so they may affect groundwater.
