    Byrnecut at Jabal Sayid: 15-year underground contract lessons for mine planners

    First reported on International Mining – News

    30 Second Briefing

    Byrnecut is marking 15 years at the Jabal Sayid underground copper mine near Medina, where it has managed ramp and decline development, longhole stoping and paste backfill under a life-of-mine contract with Ma’aden Barrick Copper Company. The contractor’s scope has expanded from initial access and infrastructure development to full production mining, fleet maintenance and training of a largely Saudi workforce, supporting output from multiple ore lenses down to more than 1,000 m depth. Its long-term presence signals continued reliance on international underground specialists as Saudi Arabia courts new greenfield projects ahead of the 2026 Future Minerals Forum.

    Technical Brief

    • Saudi Arabia’s reliance on international underground contractors at Jabal Sayid is shaping expectations for new greenfield mining projects ahead of 2026.

    Our Take

    Saudi Arabia features in only a small subset of the 419 Mining stories in our database, so Byrnecut’s 15‑year run at Jabal Sayid signals that underground contractors with an established local track record may have an edge as the Kingdom scales up its mining ambitions.

    With the article’s time horizon aligned to the 2026 Future Minerals Forum, Jabal Sayid gives Byrnecut a high‑profile reference site in the Riyadh region just as Saudi authorities are using that forum to showcase operating success stories to attract new project capital and partners.

    Among the 825 Projects/Contract Award pieces in our coverage, long-duration underground contracts like this are relatively rare, suggesting that continuity at Jabal Sayid could reduce interface risk for future brownfield expansions or nearby project tenders in the Kingdom.

    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.
