GAM is a global leader in the supply of tantalum ore, a raw material used by the Supermetals business in the manufacture of high-end products to the aerospace, electronics and other industries. Cabot will maintain its mining operation in Manitoba, Canada, where the company mines cesium for its Specialty Fluids Business and tantalum.
