    Copper price sets new London record: supply squeeze signals for mine planners

    Copper price sets new London record: supply squeeze signals for mine planners

    First reported on MINING.com

    30 Second Briefing

    Copper prices on the London Metal Exchange hit a new record above $11,400 per tonne after a surge in warehouse withdrawal orders signalled rapidly tightening available stocks and pushed the global benchmark up more than 30% year-to-date. Traders are diverting large volumes of metal to US ports as Comex futures price in potential 50% tariffs on primary copper from 2027, while producers prepare record 2026 premiums for European and Asian buyers. Supply risk is amplified by mine disruptions at Ivanhoe’s Kamoa-Kakula complex in the DRC and Glencore’s 40% output drop since 2018, raising the prospect of a Q1 2026 squeeze.

    Technical Brief

    • Price action breached a fresh intraday high above $11,400/t before settling near $11,100/t.
    • July Comex copper futures previously hit a record when markets pre‑positioned for a possible 50% US tariff.
    • Trump’s current tariff decision targets only value‑added copper products, but explicitly leaves primary forms under review for 2027.
    • Ivanhoe Mines has cut guidance at the Kamoa‑Kakula DRC complex due to ongoing post‑flooding recovery constraints.
    • Chinese smelters’ 2026 supply negotiations are described as difficult, with miners holding stronger leverage on terms.
    • For project planning, long‑lead copper‑intensive infrastructure may need revised capex contingencies and procurement lead times.

    Our Take

    With LME copper up about 30% this year and tin futures also near multi‑year highs in the recent tin‑market piece (14 November 2025), our database is signalling a broader tightening across multiple LME‑traded base metals rather than a copper‑only squeeze.

    The anticipated 50% US tariff on copper imports from July and potential levies on commodity‑grade copper from 2027 will likely push US buyers to secure more supply from Latin American projects, echoing the IDB/EU‑backed push to build copper value chains in the region highlighted in the Latin America critical minerals article.

    Glencore’s roughly 40% drop in copper output since 2018, combined with the Kamoa‑Kakula complex emerging as a key Democratic Republic of Congo supplier, suggests new African production is increasingly offsetting legacy producer decline in our copper‑tagged coverage.

    Young-Davidson mine disruptions: seismic and power impacts explained for engineers

    Alamos Gold expects second-quarter output from its Young-Davidson underground mine in northern Ontario to fall to 130,000–135,000 oz, about 12% below prior guidance, after two seismic events damaged infrastructure and cut access to two higher-grade stopes, compounded by a three-day storm-related power outage. Consolidated 2026 production is now projected below full-year guidance with unit costs rising, with revised figures due in July. Production stability is shifting to the Island Gold District, where underground mining rates are planned to increase from 1,500 to 2,000 t/d and the Magino mill ramp-up targets 10,000 t/d by Q3.

    Trinity Metals’ 20% US tungsten supply: project scale and offtake notes for engineers

    Trinity Metals has doubled exports from its Nyakabingo tungsten mine in Rwanda to Global Tungsten & Powders, now supplying up to 20% of US primary tungsten concentrate consumption, with more than 320 tonnes of 65–70% WO₃ wolframite shipped since a 2025 offtake deal with Traxys. The 1,600-hectare Nyakabingo concession holds an estimated 30,000 tonnes of recoverable tungsten, is licensed for 25 years from 2015, and is undergoing deep drilling to expand resources. Trinity plans to triple production and is targeting a $100–$200 million international listing, positioning Rwanda as a key conflict-free 3T supplier amid Chinese export restrictions.

    SMRs and mining’s nuclear reality check: key power-planning takeaways for engineers

    Small and micro modular reactors (SMRs and microreactors) sit at the bottom of miners’ low‑carbon power options, despite intense promotion of 300 MW‑class SMRs, AI‑optimised reactor operations and bullish uranium price forecasts. Developers are pitching factory‑built, modular units for remote sites and off‑grid mines, but operators still prioritise proven renewables‑plus‑storage, grid power and gas or diesel hybrids. For mine planners and power engineers, nuclear remains a long‑term possibility rather than a near‑term procurement item for new pits, expansions or remote processing hubs.
