    Fortuna’s doubled Séguéla ounces: mine life, plant expansion and capex notes

    Fortuna’s doubled Séguéla ounces: mine life, plant expansion and capex notes

    First reported on MINING.com

    30 Second Briefing

    Fortuna Mining has lifted Séguéla’s proven and probable reserves to 13 million tonnes at 2.81 g/t for 1.2 million oz. and doubled indicated resources to 6 million tonnes at 4.12 g/t, extending life of mine to 7.5 years and triggering expansion studies in Côte d’Ivoire. Technical work is assessing a 25% plant capacity increase from the 1.25 Mt/y 2023 design to 2–2.5 Mt/y, with low-capex debottlenecking targeting 1.75 Mt/y throughput in 2026. Kingfisher now contributes 3.5 Mt at 2.28 g/t in reserves and the Sunbird underground project holds 3.6 Mt at 4.34 g/t indicated, pending an underground mining study next month.

    Technical Brief

    • Latest estimate adds 11% contained reserve ounces versus the December 2024 statement.
    • Inferred resources increase 15% year-on-year to 8.8 Mt at 2.52 g/t for 712 koz.
    • Kingfisher enters reserves for the first time with 3.5 Mt at 2.28 g/t for 257 koz.

    Our Take

    With Séguéla’s proven and probable reserves now at 13Mt grading 2.81 g/t versus 9.8Mt at 3.37 g/t a year earlier, Fortuna Mining is effectively trading some grade for mine life, which typically favours mill expansion and higher throughput strategies over selective high‑grade mining in Côte d’Ivoire.

    The planned 25% plant capacity increase at the Séguéla mine, targeting 2–2.5Mt/y by 2026 from 1.25Mt/y at commissioning, positions Fortuna Mining among the more aggressive brownfield expanders in our recent gold coverage, signalling confidence in both resource conversion at Sunbird/Kingfisher and regional operating stability.

    Allied Critical’s 13Mt measured and indicated tungsten trioxide resource in Portugal, at 0.21% WO₃, gives Fortuna group exposure to a critical mineral alongside gold, which may become strategically useful if EU supply-chain policies continue to favour domestic tungsten projects.

    Atlantic Nickel record output at Santa Rita: process and UG transition notes for planners

    Atlantic Nickel’s Santa Rita nickel sulphide mine in Bahia, Brazil, delivered a record 12,464 t of nickel concentrate in August, with metallurgical recovery reaching 86.72%, the highest since operations restarted under Appian Capital ownership. The performance comes as the operation advances its transition from open pit to underground mining, signalling stable plant performance and effective ore blending during a complex changeover. For process and mine planners, the numbers suggest current comminution and flotation circuits are coping well with evolving underground feed characteristics.

    Advanced Navigation US plant: GPS-denied mine positioning insights for engineers

    Advanced Navigation America has opened a US manufacturing facility to scale production of its inertial navigation and robotics systems for GPS-denied underground and surface mines, reducing reliance on vulnerable, legacy GPS-based infrastructure. The plant will build mining-grade INS/IMU units and navigation systems designed to maintain centimetre-level positioning in dust, blast-induced shock and long-haul drifts where satellite signals are unavailable or intermittent. For mine operators, this supports more reliable autonomous haulage, drilling guidance and fleet tracking without installing extensive fixed beacons or repeaters.

    Multotec Zambia expansion: supply chain and uptime takeaways for mine engineers

    Multotec Zambia is marking its 25th anniversary in 2026 by opening a new Central Africa Regional Head Office that will expand local manufacturing, assembly and service support for the Zambian and regional mining sector. The facility is intended to bring Multotec’s process equipment expertise and technology—such as wear linings, screening media and cyclones—closer to copper and cobalt operations that currently rely heavily on imported or South African-supplied components. For mine operators, increased in-country capacity should shorten lead times for critical spares and enable more responsive on-site technical support.
