Summary
This week crystallized the new paradigm in critical minerals: governments as direct stakeholders, not just regulators. The U.S. Department of War secured a 10% stake in Trilogy Metals for Alaska copper-cobalt development, China expanded rare earth export controls to strangle global supply chains, and copper prices surged to 16-month highs as Grasberg remains offline. With lithium, rare earths, and now base metals under federal ownership or export restriction, the message is clear—strategic minerals have become instruments of statecraft. Market forces alone will not determine allocation; national security imperatives will.
Key Points
U.S. Takes 10% Stake in Trilogy Metals, Unlocking Alaska's Ambler Mining District
The Department of War will invest $35.6 million to acquire 10% of Trilogy Metals and gain warrants for an additional 7.5% stake, contingent on construction of the 211-mile Ambler Road. President Trump reversed Biden's rejection of the road permit, opening access to copper, cobalt, zinc, lead, gold, silver, gallium, and germanium deposits in Alaska's Northern Brooks Range.

Impact: Trilogy shares surged over 225%, valuing the company near $1 billion. The deal includes board representation and debt restrictions through 2029. Trilogy holds 50% of the Upper Kobuk Mineral Projects via joint venture with South32.
China Expands Rare Earth Export Controls, Adds 5 Elements to Restricted List
Beijing's Ministry of Commerce announced the most aggressive rare earth restrictions to date, expanding controls to 12 of 17 rare earth elements and implementing a "0.1% rule" requiring export licenses for any product containing Chinese-origin rare earths above that threshold. The rules also prohibit Chinese citizens from supporting overseas rare earth projects without government approval.

Context: China processes 90% of global rare earths. New restrictions target defense contractors, semiconductor firms, and add holmium, erbium, thulium, europium, and ytterbium to the controlled list. Timing precedes Trump-Xi summit in Seoul.
Copper Prices Hit 16-Month High as Grasberg Mine Declares Force Majeure
Copper surged to $10,172/ton in London following Freeport-McMoRan's force majeure declaration at Indonesia's Grasberg mine. The world's second-largest copper mine remains offline after a September landslide, with production not expected to return to pre-incident levels until 2027.

October 9, 2025: https://www.mining.com/featured-article/ranked-top-20-biggest-copper-mines-2025/ MINING.COM
Market Response: Freeport shares fell 10.4%; rivals Glencore (+3%), Teck (+5%), and Antofagasta (+7.4%) rallied. Goldman Sachs projects copper market could swing into deficit this year.
Teck Resources Slashes Copper Guidance by 11% on Operational Setbacks
Canadian miner Teck cut full-year copper production outlook to 415,000-465,000 tonnes (down from 470,000-525,000) due to persistent issues at Quebrada Blanca (Chile) and Highland Valley Copper (Canada). The revision compounds supply tightness from Grasberg disruption.

Analysis: With Grasberg offline and Teck cutting guidance, copper supply deficit scenarios accelerate. BMO Capital Markets notes 60% of Freeport's production comes from Americas, limiting total impact.
U.S. Formalizes 5% Equity Stake in Lithium Americas' Thacker Pass
The Department of Energy completed a 5% ownership position in Lithium Americas and the Thacker Pass lithium mine in Nevada. The deal includes $435 million first draw on federal loans with $182 million in deferred debt service over five years.

Pattern: Following MP Materials, Lithium Americas, Intel, and now Trilogy Metals, the administration's equity-for-security model is standard operating procedure.
Why It Matters
Alaska as Strategic Mineral Province
Trilogy's Ambler district holds world-class copper-cobalt-zinc deposits, but the region has been inaccessible. Trump's reversal of Biden's road rejection unlocks resources comparable to major Canadian and Chilean districts. The 211-mile Ambler Road is now "critical infrastructure" under federal policy.
"0.1% Rule" Extends Chinese Reach
Beijing's requirement for export licenses on products with >0.1% Chinese rare earth content applies to overseas manufacturing—an unprecedented extraterritorial control mechanism. Any product using Chinese feedstock, even if processed abroad, now requires MOFCOM approval.
Copper Deficit Looms
IEA forecasts 30% supply shortfall by 2035 due to declining ore grades, rising costs, and 10-15 year mine development timelines. Grasberg represents 50% of PT Freeport Indonesia's reserves and 70% of output through 2029. Teck's guidance cut removes another 50,000+ tonnes from supply.
Federal Equity as Standard Tool
Trilogy Metals joins MP Materials (rare earths), Lithium Americas (lithium), and Intel (semiconductors) in the federal portfolio. The Department of War's involvement signals defense priorities drive mineral policy. Expect similar deals for nickel, graphite, and cobalt assets.
Rare Earth Leverage Before Summit
China's October 9 announcement—two weeks before the expected Trump-Xi meeting in Seoul—positions rare earths as central to trade negotiations. Washington must decide: accept Chinese dominance or accelerate costly domestic alternatives.
Indonesia's Battery Metal Ascent
Indonesia now supplies 10% of global cobalt (up from 7% in 2023), driven by Chinese-funded HPAL nickel projects. As second-largest cobalt producer, Indonesia's output growth reshapes both nickel and cobalt markets.

Critical Minerals Spotlight
Rare Earths (Nd, Pr, Dy, Tb, Ho, Er, Tm, Eu, Yb)—China controls 12 of 17 elements under export licensing and 90% of processing capacity. New restrictions target magnets, EVs, wind turbines, semiconductors, and defense systems.
Copper—Supply deficit emerging as Grasberg (world's #2 mine) offline until 2027 and Teck cuts 2025 guidance. Prices at 16-month highs; IEA projects 30% shortfall by 2035.
Lithium—U.S. government direct equity holder in Thacker Pass. Near-term oversupply but deficits expected early 2030s. Trump admin ended EV tax credits this week, creating demand uncertainty.
Cobalt—Prices up 66% YoY to $40,420/ton despite oversupply narrative. Indonesia (10% market share) and DRC (76% share) dominate. Nickel-cobalt co-production from Indonesian HPAL projects growing 82% YoY.
Copper-Cobalt-Zinc-Lead (Alaska)—Trilogy's Upper Kobuk projects hold polymetallic deposits accessible via Ambler Road. Also contain gallium and germanium (semiconductor-critical).
Action Points
Monitor Trump-Xi Summit (late October, Seoul APEC)—rare earth access, technology transfer, and tariff negotiations will determine near-term supply chain architecture.
Track Ambler Road Permitting & Construction Timeline—211-mile industrial road must be financed and built before Trilogy warrants become exercisable. Framework agreement negotiations ongoing between Trilogy, South32, U.S. government, and Alaska Native communities.
Assess Grasberg Recovery—Freeport indicated production won't normalize until 2027. Watch for interim copper supply adjustments, force majeure duration, and competitor capacity responses.
Follow Federal Equity Pipeline—with MP Materials, Intel, Lithium Americas, and Trilogy Metals precedent, identify next targets: nickel (Talon Metals?), graphite (Nouveau Monde?), cobalt (Jervois, Electra?).
Evaluate "0.1% Rule" Downstream Impact—manufacturers using Chinese rare earth inputs must now navigate MOFCOM licensing. Expect supply chain redesign, nearshoring, and procurement delays.
Watch Critical Metals Tanbreez Development—bankable feasibility study 70% complete. With 25% output contracted and potential U.S. government interest reported earlier, project de-risking accelerates.
Monitor Copper Mine Output (Q4 2025)—Escondida, Kamoa-Kakula, Cerro Verde must compensate for Grasberg/Teck shortfalls. Watch Ivanhoe's Kamoa-Kakula flood recovery and production ramp.
Track China's Battery Materials Export Controls—October 9 announcement included lithium battery and graphite restrictions beyond rare earths. Understand scope, effective dates (staggered through December 1), and enforcement mechanisms.
