    Eldorado’s C$100M Amex stake: Perron project economics for mine planners

    Eldorado’s C$100M Amex stake: Perron project economics for mine planners

    First reported on MINING.com

    30 Second Briefing

    Eldorado Gold is committing a further C$20.6 million to Amex Exploration to restore its 27% stake, taking its total investment close to C$100 million as the Perron gold project in Quebec advances on the back of a strong April feasibility study. Perron’s stage-one plan outlines 147,000 oz/y gold output for five years at an all-in sustaining cost of $910/oz, 1.9 Mt of reserves grading 12.1 g/t at the Champagne zone, initial capex of C$193.9 million and a post-tax NPV5 of C$1.1 billion at $3,500/oz gold. The project is fully permitted for a 40,000-tonne bulk sample, is targeting toll milling at nearby facilities such as Eldorado’s Lamaque-Sigma complex, and has funding in place for up to 100,000 metres of drilling across the expanded 570 km² land package.

    Technical Brief

    • Feasibility study assumes a 17.5‑year mine life, with two years of pre‑production development.
    • Proven and probable reserves at Champagne zone total 1.9 Mt at 12.1 g/t Au (774,000 oz).
    • Post‑tax payback is modelled at 0.5 years at US$3,500/oz gold price.
    • Average operating cost over life of mine is estimated at US$617/oz, excluding sustaining capital.
    • Bulk sample permit allows extraction of 40,000 t, with portal and declines expected in ~18 months.
    • Stage one envisages five years of toll‑milling operations before potential transition to owner‑operated onsite processing.
    • Flow‑through and hard‑dollar financings (~C$37.3M) support up to 100,000 m of drilling through 2026.
    • Current focus includes a 15,000 m drill programme at Perron West (Ontario) with two rigs, expanding.
    • Land position has expanded from 46 km² to 570 km² contiguous ground, including 60 km of strike.

    Our Take

    The very high post‑tax IRR (114%) and short 0.5‑year payback period reported for Perron are unusually strong compared with most gold projects in our mining corpus, suggesting that even moderate capex or schedule creep could be absorbed without destroying project economics, an important buffer in Quebec’s tightening labour and contractor market.

    Larvotto–Glencore gold offtake: project economics and process notes for engineers

    Larvotto Resources has signed a seven-year mine-gate offtake agreement with Glencore for approximately 15,000 dry metric tonnes per year of gold concentrate from its 100%-owned Hillgrove antimony-gold project in New South Wales, with Glencore handling all logistics to end customers. Combined with an existing antimony concentrate offtake with Wogen Resources, the deal locks in marketing for Hillgrove’s primary concentrates ahead of first production, with plant commissioning targeted for August. Metallurgical testwork has reported 90% tungsten recovery and a 16-fold feed grade upgrade, supporting a simple, low-cost circuit for a potential tungsten by-product.

    BuilderX remote control excavators: bottleneck insights for mine automation teams

    Remote control mining excavator specialist BuilderX, led by founder Shaolong Sui, argues that excavation—not haulage—has become the main bottleneck to further mine automation, even as autonomous haul trucks move from pilots to large fleets with clear ROI. Sui positions teleoperated and semi-autonomous excavators as the next step to unlock productivity gains where manned digging still constrains fully automated truck fleets. For mine planners and OEMs, the message is to prioritise interface standards, control latency, and operator ergonomics at the shovel face rather than only optimising haulage.

    Komatsu Mesa parts hub: maintenance and downtime impacts for mine operators

    Komatsu is expanding its western US support network with a new mining parts distribution facility in Mesa, Arizona, aimed at boosting regional availability of components for large haul trucks, loaders and drills. The site will serve dealers and mine operators across key copper and gold districts in Arizona, Nevada and neighbouring states, cutting lead times for critical items that currently ship from distant hubs. Faster delivery of high-wear parts such as GET, hydraulic components and drivetrain assemblies is intended to reduce unplanned downtime and improve fleet maintenance planning.
