Katanga Mining Ltd was a mining company operating in the Democratic Republic of the Congo with its headquarters in Canada. Katanga Mining operated a major mine complex in the Congo's Katanga Province, producing refined copper and cobalt. It claimed to have the "potential of becoming Africa's largest copper producer and the world's largest cobalt producer."
Katanga Mining formed two joint-venture projects with state-owned Gécamines to develop the mining complex: Kamoto Copper Company (KCC) and DRC Copper and Cobalt Project (DCP).
In January 2008 Katanga Mining acquired Nikanor plc for $452m.
Katanga Mining was purchased by Glencore in 2020 and it was de-listed from the Toronto Stock Exchange.
The Dima mines, consisting of Mashamba East, Mashamba West and Dikuluwe Mine were originally owned by the state-owned Gécamines before majority rights were sold to Katanga Mining and Nikanor plc in the early 2000s. Following the merger with Nikanor in 2008, Katanga sold Dikuluwe and Mashamba West to Gécamines for $825 million. In February 2017 Glencore purchased nearly all of Gecamines interests in Katanga and the larger Mutanda mine. The smaller Katanga mine is remaining closed during 2015-2017 while new processing facilities are constructed. Prior to 2015 Katanga produced 113,000 tonnes/yr of copper while Mutanda continues to produce over 210,000 tonnes/yr
In January 2018, a dike broke at Kamoto mine, causing a sodium hydrosulphide spill that damaged crops and killed fish. Four hundred and sixty households were affected. Soil contamination had not been cleaned up later in 2018.
Canada required a $20 million fine from the company in 2019 due to its unclear relationship with the Congolese authorities.
