A fluorspar-silica mine located on Kennedy Creek, approximately 27 km north of Grand Forks. Discovered in 1916 by two prospectors who mistook the green fluorite for copper mineralization.
(Hard to believe that any prospector would mistake abundant green fluorite boulders for copper mineralization. An alternate discovery story is that a woman running horses in the valley mistook the fluorite for jade -BJ)
Owned initially by Consolidated Mining and Smelting Co. of Canada Ltd. Operated intermittently between 1918 and 1942, producing 56,000 tons of ore. Produced about 36,759,501 kg of fluorspar and 1,673,000 kg silica.
Controlled by Cominco until purchased by Bob Jackson, with assistance from the late Joe Nagel, of UBC, in 1986. Mineral rights are crown granted; Jackson runs a commercial specimen operation and fee dig.
The mine is noted for its green fluorites that are a pleasant color (if not very sharp or shiny) and the tabular golden barites that it produced.
(The dominant fluorite habit is octahedral, each octahedron being composed of oriented cube faces, particularly on the crystal edges. Botryoidal and cubic habits are usually purple. Good phantoms of green over purple, and clear over green are produced. Lately, lustrous, sharp green octahedrons, some on drusy quartz, have been collected. - BJ)
It occasionally produces very fine combinations of golden barites growing on green fluorite and sometimes slightly purple fluorite, occasionally all on sparkly drusy quartz matrix.
