    Mining stocks hammered as Iran war escalates: risk signals for project teams

    Mining stocks hammered as Iran war escalates: risk signals for project teams

    First reported on MINING.com

    30 Second Briefing

    Mining equities sold off sharply as the Iran–US conflict escalated, with gold futures briefly nearing $5,000/oz before closing down 3.5% and silver trading around $83/oz, still 6% lower on the day, while copper slipped 2% to $5.83/lb. Newmont, Barrick and AngloGold Ashanti fell 7.9%, 8.3% and 10.4% respectively, Gold Fields dropped 11.6%, and platinum-focused Valterra Platinum slid 13.6% after intraday platinum price falls of up to 10%. Diversified and copper majors fared slightly better, with BHP down 5.6%, Southern Copper 5.8%, Rio Tinto 4.3% and Glencore only 2.1% helped by trading roughly 4 million boe/day of oil.

    Technical Brief

    • Newmont and Barrick traded heavily, with 14 million and 23 million shares changing hands respectively.
    • Market capitalisations post-selloff: Newmont $129bn, Barrick $78bn, AngloGold Ashanti $58bn, Gold Fields $45bn.
    • Wheaton Precious Metals closed at $68.7bn market cap versus Franco-Nevada at $50bn after smaller losses.
    • Silver-focused names: Fresnillo’s US units dropped to $38.3bn, Pan American Silver to $26bn capitalisation.
    • Valterra Platinum ended at a $25bn valuation after intraday platinum lows just above $2,000/oz.
    • BHP retained a $200bn-plus valuation, the only mining stock ever to reach that threshold.

    Our Take

    Many of the large-cap gold and copper names hit here – Newmont, Barrick, Teck Resources and TSX-listed peers – also feature heavily in our TSX/TSXV coverage of outsized 2025 equity gains, so this drawdown is coming off a base where several miners had already doubled or more year-on-year.

    With copper still around $5.83/lb despite a 2% daily drop, operators like Freeport-McMoRan, Southern Copper and Antofagasta remain in a price environment that, in our database, has been underpinning aggressive growth and M&A plans rather than cutbacks, suggesting this sell-off is more sentiment-driven than fundamentals-led for copper-heavy portfolios.

    The fact that diversified traders such as Glencore, with roughly 4 million boe/d of oil-equivalent trading, moved less than single-commodity producers in this rout reinforces a pattern in our recent coverage: integrated exposure to oil and gas has been cushioning volatility for some mining houses during geopolitical shocks centred on the Middle East.

    King’s Japan visit: fuel security and critical minerals lens for project teams

    Fuel security concerns will dominate Federal Resources Minister Madeleine King’s visit to Japan this weekend, with talks expected to focus on diesel and LNG supply chains and Australia’s role as a long-term energy exporter. King is also set to discuss Japanese investment in Australian critical minerals projects, including lithium, nickel and rare earths, amid pressure to diversify away from single-country processing hubs. Outcomes could influence future offtake agreements, funding for new mines and refineries, and infrastructure for secure fuel storage and shipping routes.

    Gold and silver price weakness: planning implications for mine project teams

    Gold slipped below $5,100/oz on Friday, touching about $5,020 and heading for a second straight weekly loss as the Middle East war drives up oil and gas prices and keeps interest rate cut expectations low. The metal has traded in a tight $5,000–$5,200/oz range since an early-month spike after the US-Israeli strike on Iran, and is now almost 9% off its late-January record near $5,600/oz, though still 17% higher year-to-date. Silver fell almost 5% to just above $80/oz, with only a 10% gain so far in 2026.

    Rio Tinto’s Nemaska lithium plant slowdown: schedule and feed risks for mine planners

    Rio Tinto is slowing construction of the Nemaska lithium hydroxide conversion plant at Bécancour, Quebec, cutting its contractual workforce by about 50% while keeping several hundred workers on site, but still targets commissioning this decade and first production in 2028. The plant is roughly 70% complete, designed for 32,000 tonnes per year of lithium hydroxide, with Rio planning US$300 million of investment alongside a C$200 million commitment from the Quebec government, which retains 46.1%. Nemaska’s integrated project is based on a 26‑year Whabouchi open‑pit/underground mine producing 200,000 tonnes of spodumene concentrate annually, though Rio is reassessing feed against its Galaxy hard rock project, with a decision due in H2 2026.
