    AngloGold’s 4.9Moz Nevada project: economics and capex lens for mine planners

    First reported on MINING.com

    30 Second Briefing

    AngloGold Ashanti has completed a pre-feasibility study for its Arthur project in Nevada’s Beatty district, confirming 4.9 million oz of gold reserves across the Silicon and Merlin deposits and outlining an initial nine-year mine life with average output of 500,000 oz/y. More than 95% of mineralisation is oxide, suited to bulk mining and conventional processing, with all-in sustaining costs estimated at $954/oz and initial capex at $3.6 billion. Using a $1,950/oz base case, AngloGold reports after-tax NPV (5%) rising from $1.7 billion at $2,715/oz to $3.4 billion at $3,500/oz, with feasibility work starting June alongside environmental and hydrological baseline studies.

    Technical Brief

    • Reserve statement dated end-2025 uses a $1,950/oz gold price assumption for pit optimisation.
    • Silicon and Merlin discoveries, made in 2018, underpin the Arthur project resource base in Beatty.
    • AngloGold acquired Augusta Gold for C$152 million in July to consolidate its Nevada greenfield hub.
    • Feasibility-stage work commencing June includes environmental, hydrological and community baseline studies to support permitting.
    • After-tax NPV at 5% is projected to double from $1.7 billion to $3.4 billion between $2,715–3,500/oz.

    Our Take

    With an estimated AISC of $954/oz for the Arthur gold project, AngloGold Ashanti would sit well below the marginal cost producers highlighted in our recent gold-price coverage, giving the Nevada asset more resilience if the futures market weakness seen in March persists.

    The $3.6 billion initial capital cost against a 4.9Moz reserve base implies a capital intensity that is on the higher side for US gold projects, which likely explains why the market reaction in New York focused on long-life, low-cost optionality rather than near-term free cash flow.

    Silicon’s recent Thayer Lindsley Discovery of the Year recognition in our database underscores that the Beatty district is emerging as a flagship growth hub for AngloGold Ashanti, complementing its portfolio reshaping moves such as selling Côte d’Ivoire projects to Resolute Mining earlier this month.

    Trump ‘a gold person’: price spike and safe‑haven signals for mine planners

    Gold prices jumped up to 3% to more than US$4,550/oz on Friday, heading for their first weekly gain since the Iran conflict began, after weeks of war-driven volatility and earlier price weakness. During his first Cabinet meeting since the US strike on Iran over three weeks ago, President Donald Trump called himself “a gold person” and backed the metal as “real stuff” that “you can’t imitate”, reinforcing bullion’s safe-haven narrative. A federal arts commission has also approved a 24‑karat commemorative coin design bearing Trump’s face for the US 250th anniversary.

    Paragon BC PhotonAssay–Veracio lab: near-real-time geochem for drill planning

    Paragon Advanced Labs has launched a British Columbia laboratory that combines Chrysos PhotonAssay™ with Veracio’s rapid, non-destructive core scanning to deliver near-real-time whole-rock geochemistry. The service targets BC’s tight exploration windows and assay backlogs by generating gold and multi-element data quickly enough for decisions while drilling is still under way. For geologists and drill planners, this enables dynamic hole steering, earlier vectoring towards mineralised structures, and reduced reliance on delayed conventional fire-assay workflows.

    Santa Rita underground portal first blast: design and schedule notes for mine planners

    Atlantic Nickel and Appian Capital Advisory have fired the inaugural blast for the first underground access portal at the Santa Rita nickel mine in Bahia, Brazil, marking the physical start of the open-pit to underground transition. Portal and associated preliminary works are progressing in parallel with completion of the underground Definitive Feasibility Study, allowing mine design, scheduling and ground support assumptions to be validated against actual rock conditions. For geotechnical and planning teams, this sequencing reduces schedule risk and enables earlier refinement of underground development and ventilation layouts.
