    Lundin Mining Caserones hybrid 930E: decarbonisation and haulage notes for planners

    Lundin Mining Caserones hybrid 930E: decarbonisation and haulage notes for planners

    First reported on International Mining – News

    30 Second Briefing

    Lundin Mining’s 70%-owned Caserones copper mine in Chile has become the first active operation to run an ultra-class haul truck with a hybrid-electric system, retrofitting Komatsu 930E truck #330 with a Cummins First Mode kit. The retrofit converts the diesel-electric truck to a hybrid configuration using an onboard energy storage system to capture and reuse braking energy on haul cycles. For mine planners and maintenance teams, the project provides an in-field reference for fuel burn reduction, potential payload-neutral decarbonisation, and integration of hybrid powertrains into existing 930E fleets.

    Technical Brief

    • Hybrid package is designed as a bolt-on kit, avoiding full truck replacement or major chassis modification.
    • Energy storage system is configured to absorb high-power braking events typical of steep ramp haul profiles.
    • Regenerated energy is redeployed to traction, reducing peak diesel generator loading on uphill segments.
    • Installation on an operating production truck allows fuel, cycle time and maintenance data under real duty conditions.

    Our Take

    Caserones already features in our database for a proposed US$150 million upgrade aimed at sustaining copper-molybdenum output in Chile, so deploying a hybrid Komatsu 930E here suggests Lundin Mining is testing decarbonisation and efficiency levers at a flagship asset before rolling them across its wider fleet.

    With Lundin Mining holding 70% of Caserones and having recently cut group copper guidance, incremental productivity or fuel savings from the Cummins/First Mode retrofit could help offset pressure on unit costs at this Chilean operation without waiting for full fleet replacement cycles.

    Cummins appears repeatedly in our coverage across both mining and civil equipment, including grader and loader powertrains, so its role in hybridising the 930E at Caserones reinforces its positioning as a cross-sector engine supplier likely to standardise low‑emission solutions for large haul fleets in Chile and beyond.

    TerraLithium and BHE Renewables: geothermal lithium project lens for mine planners

    TerraLithium, an Occidental subsidiary, and BHE Renewables have produced lithium chloride from geothermal brines at BHE’s Calipatria geothermal plant in California’s Imperial Valley and converted it to battery-grade lithium carbonate. The partners have also directly converted lithium chloride to lithium hydroxide using a commercial-scale electrolyser at TerraLithium’s Brawley R&D facility in the US’s second-largest geothermal field, validating high-purity output against commercial processing standards. BHE Renewables plans to build, own and operate full-scale lithium production facilities in Imperial County once technical and economic feasibility is proven.

    Ground view Kazakhstan at Qarmet mines: safety, control and data lessons for engineers

    Kazakh steel and mining company Qarmet has installed an almost total underground visibility system at its eight former ArcelorMittal coal mines in Karaganda, combining helmet‑mounted cameras with live location tracking of every miner on a central control‑room schematic. Pre‑shift “health booths” at the portal process about 50 workers per hour, checking blood pressure, pulse, eye fatigue and alcohol, with roughly 1% barred from descending, and all footage stored on 1 TB helmet units and uploaded after each shift. The in‑house system, developed by teams of about 30 per mine, is paired with a privately funded medical centre delivering around 200 check‑ups a day, but raises unresolved questions about consent and long‑term use of pervasive surveillance in a company town setting.

    Gladiator–BlackRock Yukon raise: drilling scale-up and project lens for mine planners

    Gladiator Metals has raised over C$35 million in a BlackRock-led private placement, issuing 7 million flow-through shares at C$3.87 and 3 million non-flow-through shares at C$2.65, lifting its treasury to about C$50 million and its market capitalisation to C$357.9 million. The funding fully covers the 2026–2027 drilling campaign at the Whitehorse Copper project in Yukon, targeting multiple high-grade prospects across a 35 x 5 km belt. Cowley Park, with more than 300 historical holes and 700 m of defined copper-molybdenum strike, will see drill capacity doubled from three to six rigs by late summer.
