Mutanda Mining S.A.R.L (MUMI) is a producer of copper and cobalt based in the Democratic Republic of the Congo, around 40 km east of the town of Kolwezi in the Lualaba Province. 

MUMI operates three open pit mines that provide ore feed to our copper and cobalt production facilities. 

In 2017, MUMI became a wholly owned subsidiary of Glencore, one of the world’s largest diversified natural resource companies. 

In 2023, 5% of the capital of MUMI was transferred to the DRC State following the renewal of MUMI’s mining titles, as required by the 2018 DRC Mining Code. 

In April 2025, following a third-party assurance assessment completed in 2024, MUMI became one of the first mines in Africa to be awarded the Copper Mark against the new Risk Readiness Assessment (RRA) 3.0 standard, illustrating the operations’ commitment to responsible production.
