    First Phosphate Bégin-Lamarche update: resource and process notes for mine planners

    First Phosphate Bégin-Lamarche update: resource and process notes for mine planners

    First reported on MINING.com

    30 Second Briefing

    A resource update at First Phosphate’s Bégin-Lamarche project in northeastern Quebec has lifted indicated resources more than fourfold to 198.5 million pit-constrained tonnes at 6% P2O5, added 6.2 million measured tonnes at 7.7% P2O5, and cut inferred resources to 89.5 million tonnes at 6.16% P2O5 from 68,345 metres of drilling in 276 holes. Metallurgical tests show a 40.4% apatite concentrate, supporting plans for a 10,000‑tonne‑per‑year iron phosphate plant and a proposed phosphoric acid facility near the deep-water Port of Saguenay, 70 km away.

    Technical Brief

    • Drilling density is high: 68,345 m from 276 holes underpin the current block model.
    • Bégin-Lamarche lies ~450 km northeast of Montreal and ~70 km north of the deep-sea Port of Saguenay.
    • Site proximity to existing road and power corridors reduces greenfield infrastructure requirements for mine development.
    • Metallurgical testwork confirms production of 40.4% apatite concentrate, suitable as feedstock for battery-grade phosphoric acid.
    • First Phosphate plans a 10,000 t/y iron phosphate plant near Saguenay as a downstream offtake for Bégin-Lamarche.
    • A separate phosphoric acid plant is proposed at the Port of Saguenay, providing upstream reagent for iron phosphate production.
    • Apatite’s designation as a critical mineral by Canada, the US and EU may support permitting and funding pathways.

    Our Take

    First Phosphate’s Bégin-Lamarche project in Quebec is one of the few phosphate stories in our 143 phosphate- and lithium-tagged pieces that is explicitly tied to downstream LFP cathode material, which positions it closer to the battery supply chain than most rock-phosphate juniors in the database.

    The recent conditional C$16.7 million non-repayable contribution flagged in our 3 March 2026 coverage of NRCan’s Global Partnerships Initiative indicates that Ottawa now treats Bégin-Lamarche as a strategic LFP hub, which can materially de-risk early engineering for the planned Saguenay iron phosphate facility and associated Port of Saguenay logistics.

    With indicated resources at Bégin-Lamarche now several times higher and still 89.5 million tonnes in inferred, the project’s scale is starting to resemble the larger critical-mineral builds in Ottawa’s C$12.1 billion critical minerals portfolio (2 March 2026 article), suggesting it could become a regional anchor asset for Quebec’s phosphate and LFP value chain rather than a niche feed source.

    Sandvik underground fleet at Kamoa-Kakula: haulage and maintenance lens for engineers

    Sandvik has secured an order from Kamoa Copper SA for 19 Toro® underground trucks and loaders for the Kamoa-Kakula Copper Complex in the Democratic Republic of the Congo, taking the site’s Sandvik underground fleet to more than 100 units. The equipment will support one of the world’s largest underground Sandvik fleets at a single mine, operated by the Ivanhoe Mines–Zijin Mining joint venture. For engineers, the scale signals sustained high-volume, trackless underground haulage and significant long-term demand for OEM parts, maintenance capacity, and fleet management systems.

    Metso Durarok™ primary sizer at Yenipazar mine: design and throughput notes for engineers

    Metso has secured a €25 million order from Aldridge Mineral Madencilik A.Ş., part of CVK Mining, to supply key minerals processing equipment for the Yenipazar polymetallic mine in Türkiye, including one of its first Durarok™ primary sizers. The package, booked in Metso’s Minerals segment for 2026, will support primary crushing and downstream processing for a deposit containing multiple base and precious metals. For engineers, early adoption of the Durarok™ sizer at Yenipazar will be a reference case for hard-rock primary sizing performance in Turkish conditions.

    Volvo Autona / earth autonomous haulage: key takeaways for mine planners

    Volvo Autonomous Solutions has launched Autona / earth, a commercial autonomous haulage system for mines and quarries built around an autonomous Volvo FH truck and an in-house developed virtual driver. The package is delivered as Transport-as-a-Service, with Volvo providing the vehicle automation stack, site infrastructure, operational support and maintenance rather than selling trucks outright. The system is designed to plug into existing mine haulage operations, signalling a shift towards OEM-managed autonomous fleets where OEMs assume more responsibility for uptime and performance.
