Another cornerstone of ERG Africa’s copper business, Frontier is situated on the DRC-Zambia border near the town of Sakania in the Haut-Katanga province. It comprises an open cast copper mine and processing plant. Its high-grade copper sulphide ore is treated to produce high-quality copper concentrate containing high sulphur and iron content and low impurities.

The open pit mine’s processing facilities is capable of treating more than 10Mt of copper sulphide ore and producing circa 100kt of concentrate per annum. 

We continue to investment in Frontier to extend its life. This includes the Cut 4 project, which assumes the stripping of overburden to push back the pit boundaries and expose enough economically recoverable ore to extend the mine's life to at least 2033. Cut 4 is estimated to provide additional job opportunities for more than 1,500 DRC nationals during its development phase.

The potential for a Cut 5 expansion or transition to underground is being investigated.
