    AI to boost copper demand 50% by 2040: project pipeline risks for mine planners

    AI to boost copper demand 50% by 2040: project pipeline risks for mine planners

    First reported on MINING.com

    30 Second Briefing

    Rapid growth in AI data centres, defence spending and robotics is projected by S&P Global to lift annual copper demand 50% to about 42 million tonnes by 2040, leaving a potential supply gap of more than 10 million tonnes even if recycling more than doubles to 10 million tonnes. The study attributes roughly 4 million tonnes of extra annual demand to AI and defence alone, with a further 1.6 million tonnes possible if 1 billion humanoid robots are deployed, equivalent to about 6% of today’s consumption. Global mine output is forecast to peak near 33 million tonnes in 2030 as ore grades fall and new projects stall on permitting, financing and construction risk.

    Technical Brief

    • Copper prices already exceeded $13,000/t on the LME, driven by mine outages and US stockpiling.
    • S&P notes consumption will ultimately be constrained by available supply, via price‑driven substitution and demand destruction.
    • Long development timelines, rising capex and a highly concentrated supply chain increase execution and geopolitical risk for new copper projects.

    Our Take

    The projected 42 Mt/y copper demand by 2040 would materially tighten the market for operators like Gunnison Copper and Taseko’s Florence and Gibraltar projects highlighted in our recent rankings piece, giving low-cost in-situ and brownfield expansions greater strategic leverage in offtake talks.

    With recycled copper only expected to reach about 10 Mt/y by 2040, traders such as Trafigura, Mercuria and Gunvor named in this piece are likely to see scrap and secondary material become a more contested feedstock, reinforcing the value of long-term access to high-quality recycling streams in Europe, China and North America.

    In our database of 519 Mining stories, copper consistently appears alongside ‘critical minerals’ and ‘AI’ tags, signalling that diversified majors like BHP, Rio Tinto and Glencore are increasingly framing copper growth projects as both energy-transition and digital-infrastructure plays when pitching to investors and regulators.

    Meta and Sprott in nuclear revival: demand signals and risks for uranium projects

    Meta has signed nuclear power deals with Vistra, TerraPower and Oklo for up to 6.6 GW of capacity by 2035 to run its US data centres and the Prometheus AI supercluster in Ohio, adding to a 20‑year, 1.12 GW offtake from Constellation’s Clinton plant. In parallel, the Sprott Physical Uranium Trust has bought 300,000 lb of U₃O₈ in a week, lifting holdings to about 75.2 million lb worth US$6.17 billion, as spot prices hover around US$82/lb. For miners and project developers, this combination of long‑term nuclear PPAs and aggressive physical uranium accumulation signals firmer demand visibility despite persistent SMR cost and schedule risk.

    Derrick Experience Center: fine screening test gains and risks for plant engineers

    Derrick Corporation has opened its Derrick Experience Center (DEX Center) in January 2026 to mark its 75th anniversary, creating a dedicated test hub for advanced fine screening technology. The “first-of-its-kind” facility is designed for current and prospective customers to run full-scale trials on Derrick high-frequency screens and Polyweb® urethane panels under controlled conditions, rather than relying solely on on-site pilots. The centre is intended to shorten test campaigns, de-risk screen selection, and optimise cut size and throughput for fine coal, iron ore, base metals and industrial minerals circuits.

    University of Arizona mine waste project: key processing insights for engineers

    A $3.6 million Arbor-funded University of Arizona Tailings Center project, led by mining engineer Dr Isabel Barton, is evaluating whether 17.5 billion tons of historic copper tailings in Arizona—growing by ~100 million tonnes per year—can be reprocessed to recover critical minerals and reduce environmental risk. The team is combining statewide and UAV-based remote sensing, industry tailings datasets, drilling and surface sampling, mineralogical characterisation and techno-economic analysis using magnetic separation and basic leaching. Early work has identified unexpected mineral occurrences, including arsenic, zinc and possibly tungsten, which could justify flowsheet changes to keep these elements out of future tailings.
