Welcome back to CMJ, written for people who allocate risk, not just read headlines.
20-second highlights:
Rare earths policy signal: the G7 floated coordinated price floors on rare-earth inputs, a first-of-its-kind experiment aimed at stabilizing critical magnet supply chains (following, of course, the U.S. lead).
Copper flipped to supply risk after disruptions at Freeport-McMoRan’s Grasberg mine led to a force majeure and a downgrade to global mine output forecasts; prices tagged two-month highs mid-week.
Uranium found fresh sponsorship: Sprott Physical Uranium Trust (SPUT) executed its largest weekly buy in two and a half years, while Mercuria became the first major commodity house to trade physical uranium.
China’s magnet exports rebounded to a seven-month high in August even as shipments to the US dipped year on year, underscoring shifting demand routes.
US supply security tools sharpened: the Defense Logistics Agency (DLA) set a plan to procure scandium oxide from Rio Tinto, among others, while Xerion gained DLA funding to pilot domestic gallium refinement.
Rare earths: policy moves front-run tightness
China’s rare-earth magnet exports jumped 10.2% month on month in August to a seven-month high, with overall exports up 15.4% year on year.The catch: exports to the US fell 11.8% (YoY), pointing to re-routing toward Europe and regional supply hubs.
Investors should read the mix, not just the top-line: the shipment rebound argues that downstream EV and wind supply chains are still drawing heavily on Chinese magnets, while the US is quietly substituting where it can.
Again this week, the bigger swing factor is policy rather than spot prices.The G7 is discussing price floors for rare-earth inputs, designed to absorb demand shocks, keep production viable in new jurisdictions, and reduce the temptation for predatory pricing that starves nascent Western capacity.If implemented even as a pilot, investors should expect more predictable project cash-flow modeling and a lower discount rate for permitted Western magnet projects.(We unpack the G7 idea in the Geopolitics section below.)
Investor angle: treat rare-earth equities as a policy-beta basket.
Copper: one mine’s outage shifted the curve
Supply risk returned to the narrative after Freeport-McMoRan’s Grasberg complex suffered mudflow impacts that led to a force majeure and a sharp cut to global mine-supply forecasts.Forecasts now imply a swing from a small 2025 surplus to a deficit, with price targets nudged above 10,000 dollars per tonne for next year.Futures clipped two-month highs mid-week as the market repriced.
Onshore processing capacity continued to build out.Aurubis started production at its Georgia metals recycling plant, the company’s first US smelter-adjacent recycling asset, adding domestic feed and scrap flexibility for copper and minor metals.This matters for US smelting margins and circularity premiums.
Project pipeline: Foran Mining’s McIlvenna Bay remains one of the cleaner shovel-ready copper-zinc plays in Canada, advancing engineering and offtake preparation; it aligns with Ottawa’s critical-minerals push, even if it will only dent the macro copper deficit.
Investor angle: this was the renewal of the ‘single-point failure’ risk premium.
Uranium: fresh capital, new traders, firming spot
The fund flow was unmistakable. Sprott Physical Uranium Trust (SPUT) bought an estimated 950,000 lb in the week, its largest since early 2023, taking Q3 purchases to roughly 2.3 million lb.Spot edged into the low 80s, and the bid tone in developers and producers improved.
Meanwhile, Mercuria entered physical uranium trading, the first big commodity house to do so, joining banks moving into the fuel cycle.A top-tier trader adds liquidity, optionality, and term structure depth that utilities and miners can use when negotiating contracts and inventory strategies.On the margin, that supports a firmer spot-to-term linkage.
Investor angle: utilities remain under-contracted; trader participation plus fund buying strengthens the floor.
Consider staged exposure: physical funds for liquidity, long-life Tier-1 producers for torque to term prices, and a selective SMR supply chain pick.
Watch any new ATM financing from SPUT and how far traders scale term books before year-end.
Lithium: prices quiet, exploration not
Chinese battery-grade carbonate hovered in the mid-73,000s yuan per tonne range this week, roughly flat on the month and still near cycle trough levels after last year’s reset.The quiet tape masks a steady rebuild of downstream orders and some cost relief for cathode makers.
On the ground, Highland Critical Minerals reported up to 1.18% Li₂O in early surface work at its Church project in Ontario’s Quetico belt, and it is spinning out its Red Lake gold asset to sharpen focus. For investors, high-grade outcrops do not equal resource, but they do reset optionality when the price floor hardens.
Investor angle: for now, treat lithium like a curve trade.
The G7’s rare-earth price floor experiment, explained
Finance ministers and industry officials from the G7 discussed coordinated price floors for rare-earth inputs in Chicago this week. The concept borrows from oil-market stabilization and price-cap mechanics used elsewhere.
Structure matters: the discussion focused on a voluntary, coordination mechanism that sets a reference floor for bids in strategic procurement and stockpiling, likely implemented via government entities and state-backed lenders rather than a hard market mandate (but not yet defined).The aim is to stabilize cash flows for non-Chinese mining, separation, and magnet projects so they can finance build-outs without being whipsawed by cyclical troughs or predatory discounting.
What it would change: a credible floor would reduce discount rates in project finance models, narrow offtake spreads, and encourage Western midstream investment.It would not fix bottlenecks overnight.Compliance, transparency, and WTO alignment will be debated, and any pilot will likely be narrow and time-boxed.Yet even a limited program signals to lenders that policymakers will not let strategic magnet supply chains collapse during price downdrafts.
Investor takeaway: price floors, if piloted, raise the probability that permitted Western REE and magnet projects reach final investment decision.
That rerates equity and lowers the cost of capital for private credit.
Regional chessboard
United States, supply security: the DLA outlined plans to buy scandium oxide, with Rio Tinto named among potential sources, while Xerion secured Phase I DLA funding to validate domestic gallium refinement using its DirectPlate electrolysis. These are critical to defense and semiconductors, respectively. Names might sound alike, but they sit outside the ‘rare earths table’; what they have in common is a rhyming strategic logic.
Africa, scale through coordination: policy voices pushed for AfCFTA-aligned standards and regional corridors to monetize critical minerals at scale, rather than one-off deals. That approach would deepen value chains and attract lower-cost capital.
Canada, provincial politics meets mining reality: in Labrador, the Newfoundland and Labrador NDP proposed a critical-minerals strategy tied to local infrastructure, housing, and healthcare, so mineral development lifts living standards where ore is mined. That framing is increasingly a permitting precondition.
US geological mapping: USGS and the Minnesota Geological Survey flew new airborne surveys over the Duluth Complex and Cuyuna Range under the Earth MRI program, modernizing subsurface data for nickel, cobalt, and PGEs. Expect this to pull forward discovery timelines.
Questions we should all be asking
If the G7 validates a rare-earth price floor in procurement, which Western magnet projects jump the queue for financing, and which midstream alloy lines follow fastest?
Does the Grasberg event mark the start of a higher ‘risk premium’ regime for copper, and how should smelter TCRCs and RCs reset in 2026?
With financial buyers and Mercuria active in uranium, does the market finally move from two-speed to three-speed price discovery, and what does that imply for utility contract tenors?
Will US policy explicitly back multi-metal recycling with transferable credits that narrow the capex gap for new facilities like Aurubis Georgia?
Can regional coordination under AfCFTA bring the scale and standards needed for Africa to capture more value in copper, battery metals, and PGEs?
TL;DR
Thank you for reading and for being part of the CMJ community.In markets driven by geopolitics, foresight is power. If you found it valuable, share it with a peer who needs the same edge (or keep it close and use it to your advantage).
