    Gemfields revenue down 32%: operational and safety takeaways for mine planners

    First reported on MINING.com

    30 Second Briefing

    Gemfields’ 2025 revenue fell 32% to $135.1 million and EBITDA dropped 85% to $6.2 million as disruptions at the Montepuez ruby mine in Mozambique and the Kagem emerald mine in Zambia cut production and auction volumes. Seven auctions raised $129 million, but Kagem mining was halted for five months amid weak Chinese demand and oversupply from a rival Zambian producer, while Montepuez faced low premium-ruby recoveries, rising illegal mining and a fatal incursion that killed two police officers. The group is delaying commissioning of its $70 million Montepuez processing plant into H1 2026, has sold Fabergé for $50 million and completed a $30 million rights offer, while warning that Middle East-driven diesel supply risks could hit Mozambique and Zambia operations.

    Technical Brief

    • Gemfields is assessing alternative diesel supply routes and increased on-site fuel storage to maintain critical services.
    • Operational adjustments under review include throttling diesel-intensive activities to preserve power for dewatering and ventilation.
    • Suspension of Kagem mining required maintaining pit stability and water management with minimal production traffic.
    • Delayed commissioning of the new processing plant extends reliance on existing circuits with known throughput and recovery constraints.
    • Group operating costs were cut, which may pressure maintenance, spares inventories and non-critical safety upgrades if not ringfenced.
    • For other diesel-dependent African mines, Gemfields’ “pinch point” warning reinforces the need for contingency fuel and power planning.

    Our Take

    The 34% drop in 2025 auction revenue to $129 million flagged in the 30 January piece aligns with the 32% group revenue fall here, underscoring that Gemfields’ earnings are now tightly coupled to realised auction pricing at Kagem and Montepuez rather than volume alone.

    Aeris–Constellation partnership post $14.5m copper exit: planning notes for engineers

    Aeris Resources has completed the $14.5 million divestment of its North Queensland copper assets, including the Jaguar and Mt Colin operations, to Dingo Minerals, freeing capital to focus on its Tritton and Cracow mines. The deal comprises cash, a deferred payment and a 1.25 per cent net smelter return royalty, giving Aeris ongoing exposure to future copper production without sustaining capital obligations. Aeris is now partnering with Constellation Mining Services to optimise underground development, drilling and mine planning across its remaining assets.

    Australia as ‘global resource rising star’: project and cost lens for miners

    Australia is emerging as a “global resource rising star”, with International Energy Agency executive director Fatih Birol pointing to its large reserves of lithium, nickel and rare earths plus mature iron ore and coal supply chains as key leverage in an electrified energy system. Birol flagged that Australia’s existing export infrastructure, established ESG frameworks and experience supplying over 50 per cent of global seaborne iron ore give it a strategic edge as EV and grid-scale battery demand accelerates. For miners, the message is to fast-track critical minerals projects and downstream processing while maintaining cost competitiveness against Latin American and African producers.

    Lynas–LS Eco rare earths deal: supply chain and spec lessons for engineers

    Lynas Rare Earths has signed an agreement with South Korea’s LS Eco Energy to secure a long-term pathway for separated rare earth oxides from Lynas’ Mt Weld mine and processing hubs. The deal targets neodymium-praseodymium (NdPr) and other magnet metals for LS Eco Energy’s planned downstream facilities in South Korea, integrating Lynas’ upstream concentration and cracking-leaching capacity with Korean alloy and magnet manufacturing. For mining and processing engineers, the partnership signals tighter alignment of mine output specifications with end-user magnet-grade quality and traceable non-Chinese supply chains.
