    B2Gold’s Goose mine crusher fire: operational recovery notes for engineers

    B2Gold’s Goose mine crusher fire: operational recovery notes for engineers

    First reported on MINING.com

    30 Second Briefing

    B2Gold’s new CEO Mike Cinnamond faces an immediate technical test at the Goose mine in Nunavut, where a 16 April crusher fire forced a switch to mobile crushing and a C$7 million repair and upgrade programme to reach 3,200 tonnes per day by September and 4,000 tonnes per day in 2025. Goose holds 10.9 million tonnes of probable reserves grading 6.79 g/t for 2.38 million oz., with a C$51 million 2026 exploration budget across the Back River district and studies on a potential SAG mill to lift capacity to 6,000 t/d. Company-wide, B2Gold targets 820,000–970,000 oz. gold this year at all-in sustaining costs of $2,400–$2,580/oz, while Fekola Regional satellite ore in Mali is expected to add 60,000–80,000 oz. once permitting allows trucking to the existing mill.

    Technical Brief

    • The 16 April Goose fire was confined to the crushing circuit, with no injuries or mill/power-plant damage.
    • B2Gold immediately switched to mobile crushers to maintain feed to the fine ore stockpile during repairs.
    • Goose operates under Inuit impact and benefit and 20‑year land-use agreements with the Kitikmeot Inuit Association, embedding local labour and oversight into site safety culture.
    • For other remote mining projects, the Goose incident underlines the need for redundant crushing capacity and pre‑planned fire‑damage recovery pathways.

    Our Take

    Goose’s 6.79 g/t probable reserve grade contrasts sharply with B2Gold’s global reserve grade of 1.4 g/t, implying that once the crushing failure is fully resolved the Nunavut asset is positioned to become one of the company’s key margin drivers rather than just a replacement tonne source.

    Techking–Boonray autonomous mining tyres: design and duty-cycle notes for engineers

    Techking is collaborating with Chinese autonomous haulage specialist Boonray to co-develop mining truck tyres tailored to electric and driverless fleets, where high, instantaneous torque and tighter speed control change loading behaviour. The partners are integrating tyre design into early vehicle engineering, using Boonray’s AHS control data on torque curves, duty cycles and haul-road conditions to refine carcass structure, compound selection and heat management. For mine operators, this points to tyre performance being tuned to specific autonomous truck–road systems rather than generic TKPH-based selection.

    EcoPower Mate temporary power: layout and staging insights for mine planners

    EcoPower Mate introduces a modular temporary power system for remote mines, targeting exploration camps, mobile offices, communications nodes and construction facilities that currently rely on diesel gensets. Designed for locations with shifting footprints and variable loads, the units can be redeployed as drilling pads, laydown areas or satellite camps move, reducing the need to oversize fixed generator banks. For mine planners and project engineers, the approach supports more flexible power layouts and staged infrastructure without committing to early grid extensions.

    Sedgman wins Barroso lithium FEED: design and risk notes for project engineers

    Sedgman has secured the Front-End Engineering and Design contract for the lithium concentrator plant at Savannah Resources’ Barroso lithium project in northern Portugal, following its earlier work on the process flowsheet and Definitive Feasibility Study plant design. The FEED scope will refine equipment selection, layout and mass–energy balances for the hard-rock spodumene concentrator, de-risking capital estimates ahead of a final investment decision. For geotechnical and civil teams, the move signals progression towards detailed earthworks, foundations and tailings/waste infrastructure design on what is billed as mainland Europe’s largest lithium project.
