    Mesabi Metallics Pit Viper 351 E rigs: design and haulage notes for Iron Range mine

    Mesabi Metallics Pit Viper 351 E rigs: design and haulage notes for Iron Range mine

    First reported on International Mining – News

    30 Second Briefing

    Mesabi Metallics has purchased fully electric Epiroc Pit Viper 351 E rotary blasthole rigs via distributor Road Machinery & Supplies Co for its US$2.4 billion taconite iron ore mine and processing complex on Minnesota’s Iron Range. The large-capacity Pit Viper 351 platform, typically used for 270–311 mm production drilling, will be integrated into a greenfield operation designed around high-volume, bench-scale drilling and downstream concentrator throughput. Fully electric drilling reduces diesel use at the pit, simplifies highwall ventilation design and supports future integration with autonomous drilling and fleet electrification strategies.

    Technical Brief

    • Epiroc is supplying the rigs via Road Machinery & Supplies Co, Mesabi’s regional distributor partner.
    • The drills are being procured ahead of full ramp-up to support operational readiness of the greenfield complex.
    • Partnership with a Minnesota-based distributor should streamline local parts availability, field service and commissioning support.
    • For similar large open pits, early commitment to electric drills can de-risk later fleet electrification sequencing.

    Our Take

    Epiroc’s presence across multiple recent pieces in our database – from MT65 S truck deliveries in Chile to Deep Automation haulage at Agnico Eagle’s Odyssey mine – signals that Mesabi Metallics’ $2.4 billion iron ore development in Minnesota is plugging into a supplier already pushing hard on automation-ready fleets.

    Among the 112 iron ore–linked items in our coverage, relatively few involve such large greenfield-style capex in mature regions like Minnesota’s Iron Range, suggesting this project could become a regional anchor customer for advanced drill and blast technology in North American taconite.

    Given Epiroc’s current focus on automation and remote operation (as seen in the McArthur River and Odyssey mine articles), specifying Pit Viper 351 E rigs at Mesabi Metallics’ taconite facility likely positions the operation to adopt higher levels of autonomous drilling and data-driven blast optimisation over time.

    King’s Japan visit: fuel security and critical minerals lens for project teams

    Fuel security concerns will dominate Federal Resources Minister Madeleine King’s visit to Japan this weekend, with talks expected to focus on diesel and LNG supply chains and Australia’s role as a long-term energy exporter. King is also set to discuss Japanese investment in Australian critical minerals projects, including lithium, nickel and rare earths, amid pressure to diversify away from single-country processing hubs. Outcomes could influence future offtake agreements, funding for new mines and refineries, and infrastructure for secure fuel storage and shipping routes.

    Gold and silver price weakness: planning implications for mine project teams

    Gold slipped below $5,100/oz on Friday, touching about $5,020 and heading for a second straight weekly loss as the Middle East war drives up oil and gas prices and keeps interest rate cut expectations low. The metal has traded in a tight $5,000–$5,200/oz range since an early-month spike after the US-Israeli strike on Iran, and is now almost 9% off its late-January record near $5,600/oz, though still 17% higher year-to-date. Silver fell almost 5% to just above $80/oz, with only a 10% gain so far in 2026.

    Rio Tinto’s Nemaska lithium plant slowdown: schedule and feed risks for mine planners

    Rio Tinto is slowing construction of the Nemaska lithium hydroxide conversion plant at Bécancour, Quebec, cutting its contractual workforce by about 50% while keeping several hundred workers on site, but still targets commissioning this decade and first production in 2028. The plant is roughly 70% complete, designed for 32,000 tonnes per year of lithium hydroxide, with Rio planning US$300 million of investment alongside a C$200 million commitment from the Quebec government, which retains 46.1%. Nemaska’s integrated project is based on a 26‑year Whabouchi open‑pit/underground mine producing 200,000 tonnes of spodumene concentrate annually, though Rio is reassessing feed against its Galaxy hard rock project, with a decision due in H2 2026.
