MPA purchases concentrate from its sister company MPC and from small scale producers in Rwanda, for processing in its treatment facility and tin smelter in Gisenyi. Until April 2006, MPA’s smelter produced LME grade tin for sale on world markets. Power supply continuity issues led to the closure of the smelter. Alternative energy sources are currently being investigated

Through the Gatumba joint venture, MPA has access to mining permits on three concession areas – Gatumba, Bijyojyo and Rugendabari, which cover some 20,800 hectares in areas with known tin, tantalum, niobium and tungsten deposits. Significant infrastructure of the Gutumba JV includes an operating treatment plant, an operating hydro-electric power plant, a water supply system, workshops, offices and housing.
