    Epiroc MT65 S trucks at Pucobre: haulage design and fleet renewal notes for engineers

    Epiroc MT65 S trucks at Pucobre: haulage design and fleet renewal notes for engineers

    First reported on International Mining – News

    30 Second Briefing

    Delivery of five 65 t class Epiroc Minetruck MT65 S units to Pucobre’s Tierra Amarilla operations in Chile’s Atacama Region marks the start of a 22-truck underground fleet renewal programme. The high-capacity trucks will operate in Pucobre’s narrow-vein copper mines, where ramp geometry, ground conditions and ventilation constraints make payload-to-power ratios and braking performance critical. For mine planners and maintenance teams, the staged introduction allows progressive optimisation of haul profiles, workshop layouts and spares strategies around a single, standardised 65 t truck platform.

    Technical Brief

    • Initial batch comprises five Epiroc Minetruck MT65 S units delivered to Tierra Amarilla facilities.
    • Total fleet renewal package covers 22 underground haul trucks for Pucobre’s operations.
    • Epiroc describes Pucobre as a “strategic partner”, implying multi-year equipment and support arrangements.
    • Deliveries are being staged, enabling progressive replacement of legacy underground haulage units.
    • Centralising on a single OEM and truck class simplifies training, diagnostic tooling and parts stocking.
    • Standardised 65 t-class trucks allow more consistent haul cycle modelling across multiple mines.
    • Similar fleet renewal blocks with 20+ identical units are increasingly used to rationalise underground maintenance regimes.

    Our Take

    Epiroc’s delivery of 65 t-class Minetruck MT65 S units to Pucobre in Chile sits alongside its recent underground haulage automation work at Agnico Eagle’s Odyssey mine, suggesting these fleets are likely being specified with future automation and traffic‑management upgrades in mind rather than as stand‑alone diesel trucks.

    In our database of 900 Mining stories, Epiroc appears frequently in both ‘Projects’ and ‘Product’ tags, and the 22‑truck renewal at Pucobre’s operations in the Atacama Region reinforces Chile as one of the key Latin American testbeds for large‑scale underground fleet modernisation rather than just for surface copper equipment.

    The 22‑unit renewal plan at Pucobre is comparable in scale to other Epiroc underground truck deployments that have later been used for technology trials, such as the MT66 S eDrive test at Gold Fields’ Granny Smith mine, so operators in Tierra Amarilla may gain early access to incremental performance or digital upgrades as Epiroc refines its product line.

    Boliden Somincor–EDP–Greenvolt solar UPAC: integration notes for Neves‑Corvo mine engineers

    Boliden Somincor has partnered with EDP and Greenvolt to build Portugal’s largest self‑consumption solar generation unit (UPAC) near the Neves‑Corvo zinc mine at Castro Verde, supplying power directly to mine operations. The distributed solar plant will sit adjacent to one of Europe’s largest zinc orebodies, reducing grid dependence for high‑load processes such as hoisting, ventilation and paste backfill plants. For mine planners and electrical engineers, the project signals growing integration of large‑scale on‑site renewables into base‑metal underground operations in southern Europe.

    Aramine AutoNav Tele loader at Reward Gold mine: design and safety notes for planners

    RCT – Powered by Epiroc’s AutoNav Tele automation has been fitted to an Aramine L350D loader to support narrow vein stoping at Vertex Minerals’ Reward Gold mine at Hill End, after the unit was commissioned through Epiroc’s Orange Service Centre in New South Wales. The compact L350D, designed for ultra-narrow headings, is now operated via tele-remote AutoNav control rather than line-of-sight, allowing tramming and loading in constrained drives. For geotechnical and mine planners, this enables extraction in thinner ore lenses while keeping operators out of unsupported ground.

    Bosch Rexroth–MEDATech off‑highway electrification: integration notes for mine engineers

    Bosch Rexroth is partnering with MEDATech Engineering to deliver end‑to‑end electrification packages for off‑highway and mining mobile equipment, combining Rexroth’s mobile hydraulics, inverters and controls with MEDATech’s EV drivetrain integration capability. The collaboration targets full systems from componentry and software through to application‑specific design and build, aimed at OEMs and retrofit projects for haul trucks, loaders and other heavy units. For mine operators, this points to more standardised electric powertrain architectures and a clearer route to integrating high‑voltage drivetrains with existing hydraulic and control systems.
