Crystal Graphite Corporation Company Profile Pencil this down: Crystal Graphite mines and processes flake graphite for use in the fuel cell industry. The company excavates the mineral from open pit mines on claims covering 31 sq. mi. near the Valhalla Wilderness Provincial Park in British Columbia. The company can run 4,100 tons per year of flake graphite, but it is expanding its processing plant. Its high-purity flake graphite is sold to make bi-polar plates used in fuel cells; the rest goes to the carbon brush and friction plate markets. In 2004 the company entered the pumice market when it acquired volcanic aggregate firm CPC. COO Brian Wear holds a 35% stake in the company.
