    Carmeuse Cat Command hauling at Drummond Island: design and safety notes for planners

    Carmeuse Cat Command hauling at Drummond Island: design and safety notes for planners

    First reported on International Mining – News

    30 Second Briefing

    Carmeuse is deploying Caterpillar’s MineStar Command for hauling across its fleet of Cat 777 rigid dump trucks at the Drummond Island limestone quarry in Michigan, with implementation delivered by Caterpillar and dealer Fabick Cat. The retrofit autonomous haulage system will convert the existing 777 fleet rather than replace it, signalling growing OEM support for autonomy on mid-size quarry trucks rather than only ultra-class units. For geotechnical and quarry planners, this raises the bar on traffic management design, berm standards and interaction rules for mixed autonomous–manual operations.

    Technical Brief

    • Autonomous trucks will operate within a limestone quarry environment, with highwall, bench and dump safety berm constraints.
    • Command uses on-board obstacle detection and avoidance, tightening requirements on berm height and delineation quality.
    • Remote supervision from an off-board control room removes operators from pit traffic, rockfall and edge-risk zones.
    • Integration with MineStar fleet management allows geofenced exclusion zones around unstable faces or active drill–blast areas.
    • Mixed autonomous–manual traffic will require revised right-of-way rules, intersection layouts and signage to manage interaction risk.
    • Emergency stop and safe-park protocols must be defined for loss-of-communications events on ramps and at dumps.
    • Similar retrofits on mid-size rigid trucks could drive updates to quarry traffic codes and regulator guidance on autonomy.

    Our Take

    Fabick Cat’s role at a US limestone site reinforces how regional Cat dealers often become the de facto integrators for autonomy projects, meaning long-term support and upgrade pathways for Drummond Island will depend heavily on dealer capability rather than just OEM technology choices.

    Schlam installation kit programme: interface control and uptime gains for mines

    Schlam has launched a new in-house engineered installation kit programme for mining truck bodies and excavator buckets, giving sites a standardised, end-to-end package covering attachment supply and fit-out. Developed under a three-year product development effort, the kits are designed to integrate with Schlam’s load and haul attachments, reducing the need for bespoke on-site fabrication and ad hoc hardware selection. For maintenance and asset teams, this points to more predictable installation times, simplified spares management and tighter control of attachment interface geometry.

    Integra’s 74% reserve lift at Florida Canyon: project economics for mine planners

    Integra Resources’ updated feasibility study for the Florida Canyon heap leach mine in Nevada lifts proven and probable reserves 74% to 1.1 million oz at 0.31 g/t, raises planned output to 82,000 oz gold per year over eight years, and boosts the 5% NPV to US$601 million using a US$4,200/oz price. All-in sustaining costs climb 43% to US$2,331/oz with recovery steady at 62%, but post-tax free cash flow is projected at US$800 million, averaging US$90 million annually. Integra is drilling 42,500 metres around the existing operation to grow resources and fund its DeLamar gold-silver project in Idaho.

    DRC critical minerals strategy: price-setting and supply risks for mine planners

    Democratic Republic of Congo has shifted from price-taker to price-setter in cobalt by imposing ARECOMS-managed export quotas and planning state stockpiles of cobalt, coltan and germanium. Cobalt prices have climbed from about $21,000/t in early 2025 to just over $56,000/t, with Kinshasa forecasting $2.3 billion in fiscal revenues this year versus an estimated $617 million without intervention. Advisory input from Vectus Global and new investment moves such as Virtus Minerals’ acquisition of Chemaf signal tighter supply discipline and a push for higher value-added partnerships.
