    Copper price tops $12,000/t: supply, tariff and refining risks for mine planners

    Copper price tops $12,000/t: supply, tariff and refining risks for mine planners

    First reported on MINING.com

    30 Second Briefing

    Copper prices surged to a record $12,159.50/t on the LME, up nearly 40% year-to-date, as mine outages across Chile, Indonesia and Peru combined with looming Trump-era tariff risks to trigger a global bidding war for physical units. Analysts at BloombergNEF warn the market could slip into deficit as early as 2026, with potential shortfalls reaching 19 Mt by 2050 without major new mines and recycling. SiTration CEO Brendan Smith and BNEF’s Kwasi Ampofo both flag refining bottlenecks—China controls over 45% of global refined output—as a critical geopolitical and project-delivery risk for copper developers.

    Technical Brief

    • Surge in US copper imports has diverted physical units, forcing non-US manufacturers into higher-priced spot purchases.
    • Substitution into aluminium is occurring in some fabrication, but conductivity and mechanical limits constrain wider replacement.
    • Elevated refined prices have materially increased scrap collection and processing, partially offsetting primary mine disruptions.
    • Smelters and SXEW plants require multi‑billion‑dollar capex and long lead times, slowing regional diversification of processing capacity.

    Our Take

    Codelco’s prominence in this price piece lines up with several recent items in our database where its Chilean growth and smelting plans are timed around 2026, suggesting that today’s price strength could improve the economics and financing case for those expansions.

    Benchmark Minerals appears both here and in our coverage of 2026 Chilean copper milestones, indicating that the same analytical frameworks underpinning the projected 2045–2050 demand surge are already being used to stress‑test near‑term project pipelines.

    With China consuming about half of global copper and producing more than 45% of refined output, the 2026 deficit window in this article reinforces why new smelting capacity in Chile, such as the Codelco–Glencore MoU in our related coverage, is strategically framed as a partial hedge against over‑reliance on Chinese refining.

    Copper price 2025 surge: supply shocks and project signals for mine planners

    Copper prices set fresh records above $12,000/t in London and $5.60/lb in Chicago in 2025, amid outages at Grasberg, El Teniente, Kamoa-Kakula, Quebrada Blanca II and Cobre Panamá, and mounting geopolitical friction over US tariffs and Chinese processing dominance (53.1% of global capacity). Analysts are split, with Goldman Sachs seeing a 160 kt surplus capping 2026 prices at $10,000–$11,000/t, while Bank of America and BloombergNEF project spikes to $15,000/t and a 19 Mt structural deficit by 2050. Technically significant stories include Freeport’s 400 kt sulfide leach push at Morenci, the stalled deep-shaft Resolution Copper project in Arizona, and the proposed $53 billion Anglo–Teck merger that could create a copper complex larger than Escondida’s 1.28 Mt/y output.

    Super Copper’s Cordillera project approval: permitting and drill path notes for mine planners

    Super Copper’s Cordillera Cobre project in Chile’s Atacama copper belt has secured approval for 26 exploitation concessions from Sernageomin, covering about 6,858 hectares and granting full, permanent mining rights once registration in the Copiapó Mining Registry is complete. The company reports 25 concessions already have formal court resolutions and 15 have legal extracts published in the Official Mining Gazette, with title registration now in progress. CEO Zachary Dolesky says this clears the way to submit a drill programme as soon as results from the latest exploration work are finalised.

    Gold price tops $4,500: macro drivers and project economics lens for miners

    Gold rose to a record $4,524.68/oz in early Wednesday trading before easing towards $4,450, capping a year-to-date gain above 70% driven by central bank buying, ETF inflows and safe-haven demand linked to Venezuela tensions and expected US rate cuts. Silver hit an all-time high of $72.70/oz, up more than 150% this year after an October short squeeze and ongoing supply dislocations that have left large inventories concentrated in New York pending a US Commerce Department critical-minerals probe. Platinum climbed past $2,300/oz for the first time in the Bloomberg series, extending a 10-session rally on tight supply and high borrowing costs.
