    OceanaGold electrification at Macraes & Waihi North: design and power notes for engineers

    OceanaGold electrification at Macraes & Waihi North: design and power notes for engineers

    First reported on International Mining – News

    30 Second Briefing

    OceanaGold is weighing the next phase of mine fleet electrification at Macraes and the Waihi North project after technical studies completed for its 2025 Sustainability Report, focusing on options that are both economically feasible and technically viable. Work centres on securing renewable power through new procurement and supply agreements and matching this with future electric mobile equipment requirements rather than retrofitting the current fleet. For engineers, the key signal is that mine design, power reticulation and fleet selection at these New Zealand sites may increasingly assume high-penetration renewables and battery-electric units.

    Technical Brief

    • Decarbonisation work is framed within OceanaGold’s 2025 Sustainability Report and associated technical studies.
    • Electrification assessments are focused on “future mining fleet requirements”, implying integration with upcoming mine plans and schedules.

    Our Take

    Electrification at Macraes and Waihi North will directly intersect with the oil‑price exposure highlighted in our March 2026 open‑pit gold margins piece, where OceanaGold was among operators most sensitive to diesel costs in truck‑intensive pits.

    Across our mining sustainability coverage, OceanaGold now appears frequently both in fleet modernisation (Didipio’s new Sandvik load‑haul fleet) and in AI‑driven subsurface intelligence work, signalling that Macraes and Waihi North electrification is part of a broader technology refresh rather than a standalone ESG initiative.

    MAX Power Mining–Moose Jaw hydrogen MOU: subsurface and capex notes for engineers

    MAX Power Mining has signed an MOU with the City of Moose Jaw, Saskatchewan, to advance natural hydrogen commercialisation in the Regina–Moose Jaw Industrial Corridor, centred on the Lawson Natural Hydrogen system near Central Butte, about 80 km northwest of the city. Core desorption tests from nine samples in Cambrian Basal sands above the Basement Complex discovery returned helium values up to 8.7%, averaging 4.4%, indicating a potentially valuable hydrogen–helium system. The partners aim to leverage existing regional infrastructure and policy support to move the project towards commercial validation.

    Water shortages and mining projects: schedule and design takeaways for engineers

    Water scarcity and multi‑year permitting delays—often two to four years for discharge and dewatering approvals in the western US—are increasingly stalling otherwise bankable mines, with water risk now affecting project schedules, financing and national credit profiles. Consultants such as Woodard & Curran report that “credible water stories” are becoming as critical as ore grades, pushing operators towards closed‑loop recycling and non‑traditional sources. US firms Genesis Systems and Atoco are deploying atmospheric water generation units, including Genesis’ containerised WaterCube systems producing over 1,000 gallons per day off‑grid, now trialled at mine sites.

    Nouveau Monde’s Matawinie graphite mine: capex, schedule and offtake lens for engineers

    Nouveau Monde Graphite has approved construction of the Matawinie open-pit mine in Saint-Michel-des-Saints, Quebec, designed to produce about 106,000 tonnes per year of graphite concentrate over more than 25 years and powered by the provincial hydroelectric grid. The company has secured roughly $644.5 million in equity and debt, with total capex for Matawinie and the Bécancour battery material plant now estimated at about $634 million after downsizing the plant from the 2025 feasibility study. A 30‑month build is planned to reach full production by end‑2028, with 75% of output under offtake, including a seven‑year, 30,000‑t/y fixed‑price contract with the Government of Canada.
