What Chemaf does

Chemaf SA is a privately held copper and cobalt mining company operating in the Democratic Republic of the Congo, headquartered in Dubai through its parent Chemaf Resources Ltd. and part of the Chemaf Group (Shalina Group Ltd.). Founded in 2001 and granted mining rights to the Etoile mine in 2003, the company has over 20 years of operating history in the Haut-Katanga and Lualaba provinces and currently employs 4,300 people across two operational sites. Chemaf's output consists of two commodity streams: LME Grade A copper cathode and cobalt hydroxide concentrate, both of which are sold into global markets under a B2B sales-led model targeting EV battery manufacturers and the broader clean-energy industrial buyer base, with prices determined by London Metal Exchange reference rates.

Chemaf's core technology stack is built around SX-EW (Solvent Extraction - Electrowinning) processing for oxide ores, augmented by a 5,000-tpd flotation plant and a 400-tpd roaster for sulphide and mixed ore treatment. The operating asset is the Etoile mine in Lubumbashi, which delivered over 275,000 tonnes of copper and 50,000 tonnes of cobalt hydroxide cumulatively over the past two decades and was recognized in 2019 as the world's fourth-largest cobalt mine. Two expansion projects drive the growth pipeline: Etoile Phase II, commissioned in 2023 with a US$144 million processing plant adding 25,000 tpa copper cathode and 4,000 tpa cobalt hydroxide; and the Mutoshi project in Kolwezi, designed for 50,000 tpa copper and 16,000 tpa cobalt hydroxide from an integrated SX-EW complex processing 3.9 million tpa of run-of-mine ore. Combined peak capacity is 75,000 tpa copper cathode and over 20,000 tpa cobalt hydroxide, supported by ISO 9001/14001/45001 certifications and consecutive Responsible Minerals Assurance Process (RMAP) recognition.

Chemaf's revenue model is direct commodity sales under LME-based pricing, with no subscription, SaaS, or other recurring software-style monetization. The company is privately owned and underwent an ownership transition in March 2026 when Virtus Minerals Inc., in partnership with Lloyds Metals and Energy Ltd., acquired Chemaf SA with approvals from the DRC Ministry of Mines and Gécamines S.A., the state mining partner at Mutoshi. The DRC government retains a 5% stake in Chemaf SA. Cumulative capital investment across Etoile Phase II and Mutoshi is US$660 million, of which approximately US$570 million has been deployed and US$250-300 million remains through to production. Chemaf has also been formally identified by the U.S. Department of State as one of three foundational projects for the U.S.-DRC Critical Minerals Strategic Partnership Agreement, positioning the company inside U.S. clean-energy supply chain policy.

Direct peers

• Ivanhoe Mines: Operates the Kamoa-Kakula copper complex in DRC's Lualaba province (same province as Chemaf's Mutoshi project). While copper-focused, it shares the same DRC Katanga belt, processing technologies, and offtake customer base as Chemaf.
• MMG Limited: Through its subsidiary, operates the Kinsevere copper-cobalt mine in Haut-Katanga, DRC, producing copper cathode and cobalt hydroxide. Closely comparable geography, commodity mix, and processing approach to Chemaf's Etoile and Mutoshi operations.
• First Quantum Minerals: Operates the Sentinel copper mine in the DRC's North West province and previously the Frontier mine. Produces copper cathode for global markets with comparable LME-grade output and benefits from similar Western-aligned DRC positioning.
• Eurasian Resources Group (ERG): Operates the Metalkol Roan Tailings Reclamation (RTR) facility in DRC, one of the world's largest cobalt producers from tailings. Directly competes with Chemaf in cobalt hydroxide markets and shares DRC geopolitical exposure.
• Glencore plc: Global mining major that operates the Mutanda and KCC (Kamoto Copper Company) copper-cobalt complexes in the DRC's Katanga belt, making it the most direct comparable in geography, commodity mix, and customer base to Chemaf.
• China Molybdenum (CMOC): Operates the Tenke Fungurume copper-cobalt mine in DRC, one of the largest copper-cobalt operations globally. Direct competitor to Chemaf in the same Katanga copper belt with overlapping product offering (copper cathode and cobalt hydroxide).

Regional players

• Société Minière de Bakwanga (MIBA): DRC state-affiliated mining company and counterpart to Gécamines-style state mining entities. While primarily diamond-focused, it shares the DRC mining regulatory environment and partnership structures that Chemaf navigates with Gécamines.

Broad incumbents

• Umicore: Belgian materials technology group that refines cobalt and produces cathode materials for lithium-ion batteries. Comparable in the cobalt value chain for EV/battery customers, though Umicore is downstream-focused rather than a mining operator.
• Zhejiang Huayou Cobalt: One of the world's largest cobalt refiners and a major Chinese player in the cobalt supply chain. Comparable in serving battery/EV cathode customers with cobalt hydroxide, though operates primarily as a downstream processor rather than a mine-to-metal integrated producer.
• Jinchuan Group: Chinese state-owned mining and metals group that is a major global producer of cobalt and nickel. Comparable in cobalt supply for battery applications and competes in the same end markets as Chemaf's cobalt hydroxide.
