    AI as a new driver of rare earth demand: supply risk lens for mine planners

    AI as a new driver of rare earth demand: supply risk lens for mine planners

    First reported on MINING.com

    30 Second Briefing

    Artificial intelligence is emerging as a third structural driver of rare earth demand alongside defence and electrification, with the five largest hyperscale data-centre operators planning about US$400 billion of 2025 capex and AI data centres forecast by the IEA to consume 3% of magnet rare earths by 2030. Sprott’s Steve Schoffstall links this to China’s control of about 94% of global permanent magnet production and recent Chinese export controls on military-related products. Western responses include US equity support and neodymium-praseodymium price guarantees for MP Materials, plus similar diversification moves in Australia and Japan.

    Technical Brief

    • Cooling systems in hyperscale data centres, consuming ~20% of site power, increasingly rely on rare earth magnets.
    • Sprott notes rare earth magnets are now embedded in data-centre cooling, storage, semiconductors and comms hardware.
    • Defence demand is underpinned by ~US$2.6 trillion annual global military spending and higher NATO targets.
    • NATO members are moving defence budgets towards 5% of GDP, locking in magnet demand for guided weapons and aircraft.
    • The US currently mines ~13% of global rare earths yet still imports about two‑thirds of its needs from China.
    • China controls ~94% of permanent magnet production and has imposed export controls on military‑related rare earth products.
    • Washington’s intervention includes equity in MP Materials, neodymium‑praseodymium price guarantees and loan‑backed processing plants.
    • Average mine development from discovery to production is quoted at ~16 years, constraining rapid non‑Chinese supply growth.
    • China has also restricted export of separation know‑how, adding a processing-technology bottleneck to Western refining plans.
    • For project developers, long lead times plus state price guarantees signal a policy‑driven, not purely cyclical, rare earth market.

    Our Take

    Sprott Asset Management also features in our uranium coverage, including a 2025 piece on AI-driven power demand for hyperscale data centres, signalling that the firm is positioning AI not just as a rare earths theme but as a cross-commodity demand driver for both critical metals and nuclear fuel.

    With China holding about 94% of global permanent magnet production and the US at 13% of mined rare earths, any AI-led uptick in magnet rare earths demand by 2030 heightens the strategic gap between mining capacity in the United States and downstream processing dominance in China.

    The roughly 16-year average mine development timeline in the article’s data implies that projects targeting neodymium-praseodymium and other magnet rare earths now are unlikely to be fully responsive to AI data-centre demand peaks expected by 2030, favouring brownfield expansions and non-Chinese processing upgrades in the near term.

    Yellowhead copper project consent deal: assessment and cost lens for mine planners

    British Columbia and the Simpcw First Nation have signed a consent-based agreement to govern the environmental assessment of Trekor Metals’ Yellowhead copper project in Simpcwul’ecw Territory, the first time Simpcw has applied its Indigenous-led consent process to a major mine. Trekor has submitted a Detailed Project Description to the BC Environmental Assessment Office after early engagement and additional technical work, alongside an economic impact study for construction and operations. The proposed open pit is scoped as a 90,000 t/d operation over 25 years, targeting 178 million lb/y copper at US$1.90/lb cash costs, rising to 206 million lb/y at US$1.62/lb in the first five years.

    Mining M&A wave: project quality, timelines and value signals for engineers

    Mining’s next two years will be dominated by mergers and acquisitions as producers with strengthened balance sheets but thin project pipelines move to buy reserves after a decade of underinvestment, veteran investor Rick Rule told The Northern Miner at the 2026 Rule Symposium in Boca Raton. Rule expects intensified takeover interest in copper, uranium and gold developers holding permitted or near-build assets, as long mine discovery-to-production timelines collide with tightening supply. Projects with genuine scale, robust economics and proven management teams are likely to command premium valuations.

    China gold demand at decade low: WGC signals price and project risks for miners

    China’s physical gold demand stayed near decade lows in June, with Shanghai Gold Exchange withdrawals at 87 tonnes, up 36% on May but still 27% below the 10-year average for H1 2026 as total withdrawals reached 598 tonnes. Jewellery demand weakness is keeping manufacturers from rebuilding inventories even as the gold price holds around $4,013/oz, roughly 8% lower year-to-date. In contrast, the People’s Bank of China added 15 tonnes in June, lifting reserves to 2,346 tonnes, while domestic gold ETFs saw record monthly outflows of RMB 15 billion and a 17-tonne holdings drop to 277 tonnes.
