Report: Bloomington Mine and Mill An 875- foot crosscut intersects four narrow northeast trending quartz-pyrite-galena veins (Emmons and Calkins, 1913) in granodiorite of the Royal Stock. A select sample of the vein contained .184 oz/ton Au, 1.28 oz/ton Ag, .060% Cu, .56% Pb, and .083% Zn, so it appears the vein was probably mined for its gold content. A gravity concentration and amalgamation mill was built in 1896, but was used only a few months (Emmons and Calkins, 1913). No tailings can be found today. The dump consists almost entirely of unaltered granodiorite with minor sericite alteration on pieces adjacent to the vein.
