    Chemaf sale to US-backed Virtus: project pipeline and capex lens for mine planners

    Chemaf sale to US-backed Virtus: project pipeline and capex lens for mine planners

    First reported on MINING.com

    30 Second Briefing

    Congo is poised to approve the $30 million acquisition of Chemaf by US-based Virtus Minerals, clearing the way for about $750 million of planned investment to restart the stalled Mutoshi copper-cobalt project and expand the Etoile operation. The deal, which requires state sign-off on changes of control for mining permit holders, has seen Gécamines leverage its position as lessor of a key Mutoshi permit after previously blocking a Chinese state-backed bidder. As an early test of the December US–Congo minerals pact, the transaction will signal how preferential access for US investors to Congolese copper and cobalt assets will be structured.

    Technical Brief

    • Virtus will assume Chemaf’s debts, including Trafigura’s $600 million project finance facility from 2022.
    • Trafigura’s loan funded Mutoshi construction and capacity expansion at the existing Etoile copper-cobalt operation.
    • Congo’s mines minister Louis Watum has formally notified Virtus of the state’s intention to clear the takeover.
    • Virtus signed a purchase agreement in February with trustees representing about 95% of Chemaf’s equity.
    • State miner Gécamines controls a critical Mutoshi permit that Chemaf only holds under a lease arrangement.
    • Gécamines previously blocked a competing acquisition proposal from a Chinese state-backed bidder for the same assets.
    • Congolese law requires explicit state approval for any change of control of mining permit holders such as Chemaf.
    • The Chemaf–Virtus transaction sits alongside Orion CMC’s preliminary deal for stakes in Glencore’s DRC copper-cobalt mines.
    • A proposed Mota Engil railway would connect the Congolese copperbelt to Angola’s Atlantic coast for export logistics.
    • Together with the railway and Orion CMC deals, Chemaf’s sale forms part of the December US–Congo minerals pact implementation.

    Our Take

    Within our 275 cobalt- and copper-tagged pieces, the Democratic Republic of Congo dominates African coverage, so Virtus Minerals’ move into Chemaf’s Mutoshi and Etoile assets signals continued concentration of high-grade battery metals supply in the Copperbelt rather than diversification to newer African jurisdictions.

    The relatively low equity acquisition price versus the planned US$750 million investment suggests Virtus is effectively paying for optionality on stalled copper-cobalt capacity, a pattern seen in other distressed African M&A where incoming owners treat sunk-capex assets as brownfield development plays rather than classic corporate takeovers.

    Linking Chemaf’s Congo portfolio with American Rare Earths’ Halleck Creek rare earths project in Wyoming gives Virtus exposure to both African copper-cobalt and US critical minerals, aligning with a policy-driven push in Washington to secure non-Chinese supply chains for battery and magnet metals.

    SRK Consulting and TOMRA Mining pebble sorting: energy and throughput insights for mills

    Pebble recirculation, which can account for up to 30% of mill feed and significantly raise energy use, is being re‑examined by SRK Consulting and TOMRA Mining through sensor‑based ore sorting of the pebble stream. By treating pebbles as a heterogeneous feed and diverting barren or low-value fragments via TOMRA’s sorting units, operations can cut unnecessary regrinding and reduce circulating loads. The approach targets higher throughput and lower specific energy consumption in SAG and AG circuits without major changes to existing comminution layouts.

    Buenaventura’s 16-year San Gabriel mine boost: design and geomechanics lens

    Buenaventura is weighing a 16‑year life extension for its San Gabriel underground gold mine in Peru’s Moquegua region, where current reserves exceed 1.8 million ounces and total measured, indicated and inferred resources top 2.4 million ounces. The operation, which poured its first gold bar in December 2025, is ramping from 2,000 tonnes per day by end‑2026 to a nominal 3,000 tpd in 2027, targeting more than 100,000 ounces of annual output. Around 90% of the rock mass is classed as low‑quality geomechanically, prompting adoption of a novel underground mining method in South America to improve selectivity and reduce dilution.

    Gold Fields’ INDIMIN Coach at Cerro Corona: operational insights for mine planners

    Gold Fields is reviewing its deployment of INDIMIN’s AI-based Smart Mining Coach at the Cerro Corona open-pit copper-gold mine in northern Peru, with early results presented jointly at ExpoCobre in Lima (27–29 April). The digital coach platform is being used to support operators in real time on load–haul–dump cycles and drilling, integrating fleet data and short-interval control to tighten adherence to mine plans. For geotechnical and production teams, the trial points to closer linkage between dispatch data, operator behaviour and daily pit performance.
