    Copper price hits US record: sulphur constraints and tariff risks for mine planners

    Copper price hits US record: sulphur constraints and tariff risks for mine planners

    First reported on MINING.com

    30 Second Briefing

    Copper futures on Comex jumped 2.4% to a record $6.69/lb, widening the premium over LME contracts, which rose 1.6% to nearly $14,200/t, as traders priced in possible new US tariffs on refined copper imports. Supply risk is intensifying, with Gulf disruptions choking sulphur flows, threatening sulphuric acid availability for roughly one-fifth of global mined copper and potentially curbing up to 4.8 Mt of production if the Strait of Hormuz closes. Refined output is already reacting, with China’s April production down 3% and further declines expected, even as copper prices are up more than 10% year-to-date.

    Technical Brief

    • Comex futures moved 2.4% in a single session, versus 1.6% on the LME, signalling location-specific pricing stress.
    • The LME benchmark is trading within roughly $300/t of its January all‑time high of $14,500/t.
    • Price action follows a 40% copper price increase during 2025 driven by earlier mine disruptions.
    • China’s refined copper output decline in April is already being linked to mine‑level raw material shortages.
    • Arbitrage between US and LME contracts has reopened, encouraging metal inflows into US warehouses and altering regional inventory cover.

    Our Take

    Both this piece and the 12 May copper futures article flag sulfur and sulfuric acid as constraints, underscoring that any disruption through the Strait of Hormuz could hit not just Gulf-region smelters but also sulfur-dependent leach operations that our database shows are increasingly important for marginal copper supply.

    With Comex copper at $6.69/lb and LME prices still $300/t off their peak, US-focused developers and recyclers are likely to lean on the upcoming 30 June Commerce Department report to argue for tariff or stockpile measures that lock in a domestic price premium relative to London benchmarks.

    Weir’s early-stage water management push: design and risk lessons for mines

    Early-stage water management embedded in mine design, rather than retrofitted later, is being pushed by Marnus Koorts, Director of Capital and Process at Weir, as a core variable alongside throughput and grind size. Koorts argues that integrating water balances, tailings deposition plans and pump/sump layouts from concept study stage cuts risk of flooding, unplanned dewatering and costly rework. For engineers, this means specifying pipelines, thickeners and water-recovery circuits in initial flowsheets, not as bolt-ons once pit expansion or TSF instability exposes gaps.

    ICMM names Froydis Cameron-Johansson CEO: ESG and tailings impacts for miners

    ICMM has appointed Froydis Cameron-Johansson as its next President and CEO, effective 23 November 2026, succeeding Rohitesh Dhawan after more than five years in the role. Cameron-Johansson brings senior global leadership experience from major mining houses, positioning her to influence ICMM’s work on tailings governance, Scope 3 emissions and responsible sourcing standards across its 26 member companies. Leadership continuity at ICMM matters for operators because its frameworks often feed directly into site-level ESG criteria, investor due diligence, and permitting expectations.

    McKinsey’s 2026 gold-led mining returns: key asset optimisation lessons for engineers

    Record metals and mining returns entering 2026 are being driven largely by gold, with sector-wide market capitalisation at an all-time high and balance sheets among the strongest in a decade, McKinsey’s Global Materials Perspective 2026 reports. Behind the headline numbers, overall industry productivity has stalled and value creation is increasingly concentrated in a small group of top-quartile performers. For operators, this points to growing pressure to extract more value from existing assets through operational excellence, brownfield debottlenecking and disciplined capital allocation rather than volume-led growth.
