Tenke Fungurume, DRC
The Tenke Fungurume mine's copper-cobalt deposits are believed to be one of the world's largest known copper-cobalt resources. The deposits are located on contiguous concessions which total approximately of 1,500 km2
. These concessions are located in the southeast region, DRC, approximately 175 km northwest of Lubumbashi, the provincial capital.
Freeport-McMoRan Copper & Gold Inc. (Freeport) is the operating partner holding a 56% interest. Lundin Mining holds a 24% interest and La Générale des Carrièe;res et des Mines (Gécamines), the Congolese state mining company, holds a 20% free carried interest in the project. Owing to the carried interest of Gécamines, capital funding is provided by Freeport and Lundin Mining as to 70% and 30%, respectively.
Construction started in late 2006 on open-pit and oxide ore processing facilities designed to produce 115,000 tpa of cathode copper and over 8,000 tpa of cobalt in hydroxide. Commissioning of the copper facilities occurred at the end of the first quarter 2009, and of the cobalt hydroxide facilities at the end of the second quarter. By year end 2009, full name plate capacities for both products were being achieved. Subsequent debottlenecking and plant upgrades allowed expansion to increase to 132,000 tpa of copper cathode and approximately 11,000 tpa cobalt hydroxide. A Phase 2 Expansion of the plant was completed in 2014, which has increased nameplate capacity to 195,000 tpa of copper cathode and 15,000 tpa cobalt hydroxide.
The phase 2 expansion was one of several stages of development contemplated with the objective of ultimately producing up to 500,000 tpa of copper by mining multiple deposits concession-wide.
The main highway, railroad and power line connecting Kolwezi and Likasi with Lubumbashi pass through the concessions. Scheduled air services are available between Lubumbashi and the capital Kinshasa, as well as from Johannesburg, South Africa and Zambia. An airstrip constructed on the concession can accommodate medium sized aircraft. The copper and cobalt product and bulk mine consumables are primarily transported by truck between Tenke Fungurume and ports in South Africa via a transport hub located at Ndola in Zambia.
The tailings storage facility is located to the north west of the process plant site. The entire impoundment area is lined with a high density polyethylene liner. The current location and configuration will provide containments sufficient for the full known reserves. Further expansions of the existing tailings storage facility are planned by raising and extending the dam walls and advancing the placement basis to the north of the current footprint. Conceptual location studies over the concession area have also been carried out to identify future tailings sites to meet potentially expanded production scenarios.
Electrical power is provided from the national grid. The power supply to the plant site is provided via a high voltage overhead line from the Fungurume substation to the switchyard at the plant site. The Fungurume substation has been upgraded to provide a reliable power supply to Tenke Fungurume.
Water supply is available within a reasonable distance of the mine site and plant. Appropriately spaced wells sustain the mining and plant processes, with standby capacity. Additional process water requirements come from a combination of water from the tailings storage facility supernatant return water and potentially impacted run-off stormwater collected from the waste rock stockpiles and plant site. Potable water is supplied to, and reticulated throughout, the permanent village located north of Fungurume.
