    Arafura Rare Earths CFO transition: funding and cost-control signals for Nolans

    Arafura Rare Earths CFO transition: funding and cost-control signals for Nolans

    First reported on Australian Mining

    30 Second Briefing

    Arafura Rare Earths’ long-serving chief financial officer Peter Sherrington will step down on 31 August after nearly 18 years, remaining until 31 October to manage a structured handover as the company moves towards construction of its Nolans rare earths project in the Northern Territory. Former BHP Nickel West president Angela Bigg will join as CFO on 13 July, bringing large-scale project and operational finance experience. The timing signals Arafura is locking in funding and cost-control leadership ahead of major EPC and procurement commitments at Nolans.

    Technical Brief

    • Handover period spans two months of overlap, reducing financial control risk during early works mobilisation.
    • Dual-signatory authority is likely during August–October, constraining rapid capex approvals for Nolans procurement packages.
    • Sherrington’s 18-year tenure implies deep continuity in historical cost data and feasibility assumptions for Nolans.
    • Transition coincides with pre-construction phase, when EPCM contracts and long-lead equipment commitments typically crystallise.
    • Lender due diligence on cost estimates and ramp-up schedules will need consistent messaging across both CFOs during handover.
    • Governance-wise, board audit and risk committees must manage key-person risk in treasury, hedging and offtake pricing models.

    Our Take

    With Nolans now designated a “Significant Project” under the Northern Territory’s Territory Coordinator Act and targeting a September construction start, continuity in finance leadership through to at least 31 October should help maintain momentum on government interface, debt drawdown conditions and offtake-linked funding.

    Our database shows only a handful of rare earths project stories reaching the fully integrated ore‑to‑oxide stage in Australia, so the incoming CFO will likely be dealing with a relatively complex funding and offtake stack, including Indian magnet supply term sheets and multiple export credit and strategic finance stakeholders.

    Geopolitical risk and private capital flows: gold price signals for mine planners

    Growing geopolitical tensions are pushing capital out of sovereign bonds and into private assets, a rotation market-cycle analyst Martin Armstrong links to a potential renewed gold rally from Q1 next year. Armstrong sees Europe as particularly exposed, arguing EU states face rising war-related borrowing costs and inflation as “war drums” lift long-term rates, while bond markets “give us the real story”. He warns that if gold closes below $4,000/oz weekly it could test $3,500–$3,700, but expects elections in the US, Israel and Ukraine to keep geopolitical risk elevated and ultimately drive prices higher.

    McEwen’s $55M Ontario asset sale: production growth lens for mine planners

    McEwen has agreed to sell its Fuller and Paymaster gold properties in Ontario’s Timmins district to Discovery Mining for $55 million in cash and stock, freeing capital to push a production target of 250,000–300,000 gold-equivalent ounces per year by 2030. The deal covers 210 hectares at Fuller, a 60% stake in the 179-hectare Paymaster property, and associated surface rights, consolidating Paymaster under Discovery’s Dome Mine subsidiary. Proceeds will be reinvested into the Fox Complex (Froome, Stock, Grey Fox), Nevada’s Gold Bar Complex, and Mexico’s El Gallo build, with Stock Mine slated for first ore in Q4 2026 and commercial output in Q1 2027.

    Lithium Triangle extraction hurdles: hydrogeological insights for project teams

    South America’s Lithium Triangle holds about 64 million tonnes of identified lithium resources (43% of the global 150 million tonnes), yet geologist José Cabello’s review of 43 salt flats across Argentina, Bolivia and Chile shows that variable brine chemistry, impurities and groundwater behaviour make recovery and costs highly site-specific. Salar de Atacama benefits from ultra‑dry climate, relatively clean brines and strong logistics, while other basins such as Altoandinos, Pedernales, Hombre Muerto Oeste, Rincón, Sal de los Ángeles and Sal de Vida face tighter water and hydrogeological constraints. Direct lithium extraction (DLE) could unlock lower‑grade or impurity‑rich brines, but Cabello stresses that trade‑offs between brine withdrawal and freshwater consumption mean technology selection must be tailored to each basin’s hydrology and ecosystem.
