The Company's low-capex, modular processing facilities are deployed close to these various types of material, producing high grade concentrates for sale or further refining to finished metal at the Company's downstream facilities. Production currently consists of chrome, copper and platinum group metals (PGMs). The modular processing facilities offer a platform for growth and the rapid expansion of its operational footprint. Jubilee's success is derived from operational excellence, a highly experienced management team and a pioneering Technical Development Centre.
