[2] In August 2010 the DRC government seized Frontier, the largest copper mine in the country, saying First Quantum had been "unreasonable" in refusing to renegotiate the terms of the contract.

[6] However, Reuters soon confirmed the sale of 30% of Frontier to Fortune Ahead, which already owned the other 70% of the mine through its stake in the joint venture Sodifor.

Proceeds from the sale appeared to be spent on funding Joseph Kabila's political campaign in the 2011 Democratic Republic of the Congo general election.

[7] In July 2012, ERG, known as Eurasian Natural Resources Corp Plc at the time was granted the mining licence at Frontier.

[8] In 2016, ENRC, (which was reorganized as Eurasian Resources Group) sold rights to 100% of the mine's copper to the CCS company in Zambia, which is owned by China Nonferrous Metal Mining Group's Foreign Engineering and Construction Co., Ltd. (NFC) and Yunnan Copper.
