    Iran war and nuclear build‑out: uranium market signals for mine planners

    Iran war and nuclear build‑out: uranium market signals for mine planners

    First reported on MINING.com

    30 Second Briefing

    War in Iran and a May 2025 US executive order to quadruple nuclear capacity to about 400 GW by 2050 are fuelling expectations of a new wave of reactor construction, with uranium demand already exceeding mine output by 50–60 million lb. per year. Cameco, which produces about 15% of global uranium from assets including the McArthur River high‑grade mine and owns 49% of Westinghouse Electric, has signed a nine‑year, ~22‑million‑lb. uranium supply deal with India worth an estimated US$1.9 billion from 2027–2035. Spot uranium is trading near US$86/lb., term prices around US$90/lb., and utilities are beginning to accept three‑digit pricing as long‑term uncovered requirements through 2045 widen.

    Technical Brief

    • Cameco currently has about 30% of its installed mine capacity deliberately kept idle.
    • McArthur River in Saskatchewan is described as the world’s largest high‑grade uranium mine.
    • Kazatomprom supplies roughly 20% of global uranium and co‑owns the Inkai joint venture with Cameco.
    • India operates 24 reactors with ~8 GW capacity and targets 100 GW nuclear by 2047.
    • New Delhi has selected six Westinghouse AP1000 units as part of its expansion programme.
    • US regulators have granted a 20‑year licence extension to both Diablo Canyon pressurised water reactors.
    • Cameco estimates uncovered utility requirements at about 3.1 million lb. U₃O₈ through 2045, the largest historical gap.

    Our Take

    Cameco’s projected 10.5 million lb this year from the Inkai joint venture in Kazakhstan sits against new Kazakh subsoil rules highlighted in our March 2026 coverage that tilt future uranium JVs towards Kazatomprom, suggesting Western utilities may lean more heavily on legacy assets and long‑term contracts rather than new greenfield Kazakh supply.

    Within our uranium‑tagged coverage, Cameco and Kazatomprom consistently appear as the only producers with double‑digit shares of global supply, so any acceleration in reactor build‑out in regions like Asia or the Middle East is likely to reinforce their pricing power unless idle capacity (such as Cameco’s 30% idled mine capacity) is brought back on line quickly and reliably.

    Sandvik mining leadership change: drill fleet strategy takeaways for engineers

    Sandvik has appointed Patrick Murphy as President of its Mining business area and member of Sandvik Group Executive Management, effective 1 July 2026, succeeding Mats Eriksson, who will step down ahead of his planned 2027 retirement. Murphy currently leads Sandvik’s Rotary Drilling division, giving him direct oversight of blasthole and production drilling systems that are central to large open-pit operations. The leadership change signals continuity in Sandvik’s mining equipment strategy, particularly around drill fleet technology and service models for high-production sites.

    Torex Mexico gold mine life extension: drilling and throughput lens for planners

    New drilling at Torex Gold Resources’ Morelos complex in Mexico has intersected high-grade zones, including 18 metres at 8.04 g/t gold, 33.9 g/t silver and 1.37% copper in hole MLLI-042 and 16 metres at 15.12 g/t gold in hole MLLI-048, both from depths around 470–565 metres. Additional intercepts such as 49 metres at 2.18 g/t gold and 95 metres at 1.5 g/t gold support continuity of mineralisation to at least 700 metres above sea level, remaining open at depth and along strike. Backed by a record US$77 million 2026 exploration budget and 148,000 metres of planned drilling, Torex aims to sustain 450,000–500,000 gold-equivalent oz. per year beyond 2030 by rapidly tying Media Luna, ELG underground and satellite deposits into existing plant infrastructure.

    Lion One Metals financing collapse: Tuvatu mine and debt risks for engineers

    Lion One Metals shares fell over 30% to C$0.14 after cancelling a C$15 million private placement with Arete Capital Advisors and announcing the exit of CEO Campbell Olsen just two months into the role. The Arete deal would have issued 44.26 million units at C$0.34, each with a warrant at C$0.39, and included a master services agreement making Arete operator of the Tuvatu underground gold mine in Fiji. Tuvatu, designed for about 331,400 oz/year over five years, produced only 4,200 oz last quarter amid equipment, power and development constraints, while Lion One faces a senior loan default notice from Nebari and a shareholder move to remove directors.
