    St Barbara’s Nova Scotia gold hub approval: design and ESG notes for mine planners

    St Barbara’s Nova Scotia gold hub approval: design and ESG notes for mine planners

    First reported on MINING.com

    30 Second Briefing

    St Barbara’s 15‑Mile Processing Hub in Nova Scotia has cleared the federal conformity review, triggering a 20‑day public comment and First Nation consultation period under Canada’s impact assessment regime and the new “one project, one review” cooperation agreement. The central plant is designed to treat 3 million tonnes of ore per year from the 15‑Mile, Old Austen and Old Mitchell mines, targeting over 100,000 oz of gold annually for more than 11 years based on proven and probable reserves. Redesign work claims to cut land disturbance by 23–55% across the three sites, remove several access roads and legacy facilities, and integrate remediation of historic mercury and arsenic contamination, with a feasibility study and full environmental assessment filing planned by Q3 FY2027.

    Technical Brief

    • A 20‑day public comment and Mi’kmaq/First Nation consultation window now precedes any decision on a full federal impact assessment.
    • Redesign consolidates earlier multi‑plant concepts into a single 15‑Mile Processing Hub serving 15‑Mile, Old Austen and Old Mitchell.
    • Revised layout cuts land disturbance by ~23% at 15‑Mile, ~43% at Old Austen and ~55% at Old Mitchell.
    • Several previously proposed access roads and processing facilities have been removed to shrink the project footprint and linear disturbance.
    • Design changes explicitly target reduced wetland and watershed impacts while integrating remediation of legacy mercury and arsenic contamination zones.
    • St Barbara cites ~C$5 billion in total economic activity, with ~1,386 construction and ~740 long‑term operating jobs in rural Nova Scotia.
    • Environmental Assessment Registration Document and multiple provincial/federal permits will follow, with full EA documentation targeted for Q3 FY2027 alongside the feasibility study.

    Our Take

    St Barbara’s 15‑Mile Processing Hub in Nova Scotia sits alongside its approved Touquoy stockpile reprocessing campaign (about three million tonnes over 10–14 months), signalling a strategy to sweat existing Atlantic Gold infrastructure while transitioning to a longer‑life hub-and-spoke operation.

    The 3 Mt/y central plant and >11‑year mine life at 15‑Mile align with St Barbara’s earlier 697 sq. km exploration push around the planned hub, suggesting the company is banking on additional mesothermal gold discoveries to keep the facility filled beyond the initial plan.

    Nova Scotia already features heavily in our gold coverage, and the province’s recent easing of permitting and investment in geoscience tools means the Impact Assessment Agency of Canada’s approval here is likely to be read by other gold and critical mineral proponents as a positive signal for future project timelines in the region.

    Cementation Africa early dewatering designs: key lessons for mine planners

    Cementation Africa is pushing for underground mine dewatering to be designed from the earliest study phases, with hydrogeological investigations embedded in scoping and pre-feasibility work rather than added after shaft sinking. Study Manager Mine Engineering John Goulding stresses that early characterisation of aquifers, inflow rates and pore pressures allows proper sizing and siting of pump stations, sumps and grout curtains, and integration with shaft and decline layouts. For geotechnical and mine planners, this approach reduces unplanned inflows, avoids costly retrofits and supports more reliable ground support and excavation sequencing.

    JordProxa at Lilac’s Great Salt Lake DLE plant: process design notes for engineers

    JordProxa has been selected as technology and equipment partner for Lilac Solutions’ Phase 1 commercial lithium carbonate plant on Utah’s Great Salt Lake, which targets 5,000 t/y of battery-grade lithium carbonate using direct lithium extraction. The partnership covers the downstream conversion process, integrating JordProxa’s thermal and process equipment with Lilac’s ion-exchange DLE system. First lithium production is planned for 2028, signalling a move from pilot-scale brine processing to a full commercial facility in a chemically complex salt-lake environment.

    Orica Digital Solutions’ Axis Mining support in North Bay: reliability gains for drill teams

    Orica Digital Solutions has opened an Axis Mining Technology Technical Support & Service Centre in North Bay, Ontario, extending on-the-ground backing for its orebody intelligence systems to Canadian and wider North American mines. The facility will support deployment and maintenance of Axis downhole navigation and drillhole survey tools, improving turnaround for calibration, repairs and firmware updates that previously relied on distant service hubs. For geologists and drill and blast teams, closer support should reduce downtime on production and definition drilling and enable more consistent high-precision orebody data.
