    Tía María copper mine permit revoked: project viability and risk notes for engineers

    Tía María copper mine permit revoked: project viability and risk notes for engineers

    First reported on MINING.com

    30 Second Briefing

    Peru’s Ministry of Energy and Mines has revoked Southern Copper’s permit for the $1.8 billion Tía María project, citing missing legal justification, non-compliance with mining and administrative regulations, and incomplete technical plans for waste dump design and project scheduling. The open-pit mine in Arequipa, expected to produce 120,000 tonnes of copper per year over 20 years and reported 23% complete in October 2025, now faces a full technical viability reassessment. The decision adds to roughly $7 billion in stalled copper projects amid illegal mining and comes days before Peru’s presidential election, increasing uncertainty for long-term investment and project delivery.

    Technical Brief

    • Minem’s revocation cites incomplete waste dump design and deficient project scheduling documentation as key technical gaps.
    • The ministry’s communiqué confirms a full reassessment of “technical viability” before any new authorisation is considered.
    • Social conflict history is severe: protests between 2011–2015 caused six fatalities and halted works.
    • Government’s 2019 approval explicitly conditioned construction progress on restoration and maintenance of “social stability” in the area.
    • Southern Copper only restarted on-site development activities in 2024 after authorities judged local tensions had eased.
    • Tía María is one of several copper projects contributing to an estimated US$7 billion in stalled Peruvian copper investment.
    • Parallel illegal gold flows are material to sector risk, with illicit exports projected at up to US$12 billion in 2025.
    • Southern Copper’s existing Peruvian footprint includes Toquepala and Cuajone mines plus the Ilo refinery, concentrating exposure in the south.

    Our Take

    Southern Copper and parent Grupo Mexico appear repeatedly in our recent copper-market coverage alongside majors like BHP and Rio Tinto, so the permitting setback at Tía María in Peru will likely be read by investors against a backdrop of already volatile copper and gold equities in early 2026.

    Peru’s estimated $7 billion in stalled copper projects, combined with declining output at Chilean assets such as Codelco and Escondida, suggests Latin America’s traditional copper heartlands are struggling to convert project pipelines into near-term supply just as multiple macro pieces in our database flag uncertain demand and price signals.

    The projection of up to $12 billion in illicit gold exports from Peru in 2025, contrasted with blocked formal copper projects like Tía María, signals a regulatory and enforcement imbalance that could push capital towards brownfield copper expansions (e.g. Toquepala, Cuajone, Ilo refinery) rather than new greenfield builds in higher-conflict districts.

    Graphite One Alaska–Ohio supply chain: design and capex notes for mine planners

    Graphite One has secured a Conneaut, Ohio site from Bessemer and Lake Erie Railroad (CN subsidiary) for its Active Anode Materials facility, gaining direct Lake Erie port access, multi-line CN rail, an on-site substation and room to scale. The staged build-out targets an initial 25,000‑tonne module, ultimately 100,000 tonnes per year of anode material, supplied by the post‑feasibility Graphite Creek deposit in Alaska with a planned 20‑year mine life and backed by up to US$2 billion in potential EXIM funding. A separate Ohio finishing and blending plant aims for Q4 2027 completion with 10,000 t/y initial capacity, split into 4,000 t energy storage, 3,000 t fast‑charging and 3,000 t high‑energy‑density graphite products for lithium‑ion batteries.

    Jeff Currie’s $10,000 gold call: cycle, capex and price risks for mine planners

    Gold may retreat from about $4,500/oz. towards $4,000/oz. as Jeffrey Currie, former Goldman Sachs commodities chief and now Abaxx Markets executive co-chairman, stays tactically short, citing forced central bank sales such as Turkey’s roughly 120 tonnes of disposals to fund higher energy costs. Currie still targets a long-term move towards $10,000/oz., arguing that once central banks turn dovish after an energy-driven growth shock, the trade “resets”. He links this to a broader commodity super cycle driven by capex starvation and an estimated $820 billion of 2026 spending by the “Magnificent 7 plus Oracle”.

    Nouveau Monde Graphite Matawinie mine: project and supply-chain notes for engineers

    Construction has begun on Nouveau Monde Graphite’s C$2 billion Matawinie mine in Québec, fast-tracked through Canada’s Major Projects Office and designed to produce up to 106,000 tonnes of graphite per year, which would make it the largest graphite mine in the G7. Ottawa has backed the project with financing from Export Development Canada, the Canada Infrastructure Bank and the Canada Growth Fund, plus a seven-year offtake for 30,000 tonnes of concentrate annually. The mine, 120 km north of Montreal, is expected to create over 1,000 jobs and anchor an integrated graphite-to-battery materials chain with NMG’s planned Bécancour plant.
