    Eramet’s Grande Côte IRMA 50 audit: mine planning and ESG takeaways for engineers

    Eramet’s Grande Côte IRMA 50 audit: mine planning and ESG takeaways for engineers

    First reported on International Mining – News

    30 Second Briefing

    Eramet’s Grande Côte mineral sands operation in Senegal has achieved IRMA 50 performance level, the first site in the group to complete an audit under the Initiative for Responsible Mining Assurance standard. The voluntary assessment, aligned with Eramet’s 2022 CSR roadmap “Act for Positive Mining”, covers mine planning, tailings and water management, labour and community relations, and closure planning. For engineers, IRMA 50 signals external verification of baseline practices on issues such as dredge mining impacts, rehabilitation of coastal dune systems, and control of process-water circuits.

    Technical Brief

    • For other mineral sands and dredge operations, IRMA audits provide a structured external check on ESG-critical mine design choices.

    Our Take

    Among the 922 Mining stories in our database, Senegal appears far less frequently than West African gold jurisdictions, so Eramet Grande Côte (EGC) becoming an early IRMA 50 site could set a reference point for future mineral sands and base metals projects in the country.

    Eramet’s 2022 launch of its Act for Positive Mining CSR roadmap, now tied to an IRMA 50 outcome at the Grande Côte mineral sands mine, signals that third‑party ESG verification is moving from corporate policy language to asset‑level audits, which lenders and offtakers increasingly scrutinise in due diligence.

    Within the 1,700+ sustainability‑tagged mining pieces in our coverage, IRMA certification is still mentioned in only a small subset, so EGC’s audit may give Eramet a differentiation edge when competing for permits or partnerships in other regions where social licence is more contested.

    JOEST Australia’s Pilgangoora expansion order: design and wear notes for mine engineers

    JOEST Australia has secured the largest order in its history from Pilgangoora Operations Pty Ltd for the PLS P2000 Expansion Project at the Pilgangoora hard rock lithium mine in Western Australia. The contract covers multiple vibrating screens, feeders and a primary grizzly, building on JOEST’s previous scope at the site. With the P1000 Expansion Project due to complete in 2025, the new package signals further scaling of front-end crushing and screening capacity, with implications for equipment sizing, wear-liner selection and maintenance planning in high-throughput lithium circuits.

    BHP’s first Olympic Dam block cave resource: design and cave stability notes for engineers

    BHP has declared a first underground block cave resource at Olympic Dam in South Australia, reporting 10,730 Mt at 0.59% Cu, 0.19 kg/t U3O8, 0.21 g/t Au and 1 g/t Ag in its operational review to 30 September 2026. The scale and grade support long-life mass mining beyond the existing sublevel open stoping, with block caving likely to demand extensive footprint development, cave propagation monitoring and high-capacity materials handling. Geotechnical teams will be focused on managing cave stability in the complex copper-uranium breccia-hosted system and controlling subsidence above critical surface infrastructure.

    FLANDERS hybrid cabinet on Komatsu 930E at Belle Ayr: lifecycle gains for mine fleets

    FLANDERS has completed a claimed world-first installation of its hybrid-electric control cabinet on a diesel-electric Komatsu 930E haul truck operated by Eagle Summit Resources at the Belle Ayr coal mine in Wyoming. The retrofit cabinet replaces legacy electric-drive controls to address haul truck obsolescence while retaining the existing diesel-electric drivetrain. For mine operators, the approach signals a pathway to extend 930E fleet life and prepare for future higher-level electrification without full truck replacement.
