The era of unrestricted globalization in the mining and metals sector is effectively over. In its place, a new doctrine of "resilient security" has emerged, spearheaded by the G7 and codified in a series of restrictive targets known as the "60% Rule."
Announced as part of the G7 Critical Minerals Resilience and Production Alliance, this policy marks the most aggressive attempt yet by Western economies to dismantle the concentrated dominance of single-source suppliers: most notably China: in the critical minerals sector. By 2030, G7 nations aim to ensure that no more than 60% of their imports for any high-priority mineral come from a single external country.
For the mining industry, this is not just a policy shift; it is a fundamental restructuring of the capital environment. The "Firewall" is designed to force a geographical decoupling that will require trillions in new investment, the revitalization of mid-stream processing in high-cost jurisdictions, and a likely split in global commodity pricing.
The Geopolitics of the 60% Threshold
The 60% rule was born from a vulnerability analysis that exposed the fragility of G7 supply chains. Currently, China controls approximately 60% of global rare earth production and nearly 90% of its processing. For permanent magnets: essential for electric vehicle (EV) motors and defense technology: the concentration is even higher.
By setting an explicit "diversification cap," G7 leaders are attempting to use trade policy as an industrial catalyst. The rule serves three primary functions:
- Investment Signaling: It provides a multi-decade "buy local/allied" signal to private equity and institutional investors.
- Price Protection: It paves the way for "price-gap subsidies" that bridge the cost difference between cheap, high-carbon imports and expensive, ESG-compliant domestic production.
- National Security: It treats mineral access as a defense priority rather than a commercial commodity.
The ambition does not stop at 60%. The alliance has already indicated a desire to push this threshold down to 50% "as soon as possible" after the 2030 benchmark is reached.
Lithium and Nickel: The Pilot Minerals
While the 60% rule was initially framed around Rare Earth Elements (REEs), the G7 has selected lithium and nickel as the pilot commodities for harmonized procurement mechanisms. This choice is strategic. Unlike gold or iron ore, lithium and nickel are the linchpins of the energy transition, yet their supply chains are heavily bifurcated between extraction and refining.
In the case of lithium, the "firewall" faces a significant hurdle: the refining gap. While extraction occurs globally: from the brine ponds of the "Lithium Triangle" in South America to the hard-rock mines of Western Australia: the chemical conversion process remains concentrated. To meet the 2030 targets, the G7 alliance is coordinating "demand aggregation," where member states act as a single buyer to provide long-term offtake certainty for new refineries in Canada, the U.S., and Australia.
Recent movements in the 2026 Lithium Power Map suggest that this strategy is already beginning to pull capital away from integrated Chinese ventures and toward independent "junior" miners who are willing to commit to G7-exclusive supply chains.
The Rare Earths Magnet Dilemma
The most immediate impact of the firewall will be felt in the Rare Earth Elements sector. The G7’s 60% cap is a direct challenge to the "Magnete" strategy utilized by incumbent dominant players.
Processing REEs is a chemically intensive and environmentally challenging process. Western producers have historically struggled to compete on price due to stricter environmental regulations and higher labor costs. To counter this, the G7 Alliance is exploring "plurilateral trade agreements" that would include price floors. This ensures that if a dominant supplier attempts to flood the market to crash prices and bankrupt Western competitors: a tactic seen in the mid-2010s: the new G7-aligned projects remain solvent.
Financial Instruments: Bridging the "China Gap"
The primary obstacle to the 60% rule is the "valuation gap." Projects in G7 jurisdictions are often 20% to 40% more expensive to build and operate than those in less regulated regions. To address this, the G7 is deploying several high-impact financial tools:
- Price-Gap Subsidies: Direct government intervention to pay the delta between the global market price and the production cost of an allied facility.
- Joint Procurement: Aggregating demand from G7 defense and automotive sectors to sign 10-year offtake agreements at fixed prices.
- Export Credit Guarantees: Using agencies like EXIM (U.S.) and EDC (Canada) to lower the cost of debt for projects that contribute to the 60% diversification goal.

|---|---|---|---|---|
| Rare Earth Oxides | ~85% | <60% | China | Mt Pass (USA), Lynas (AUS) |
| Permanent Magnets | ~92% | <60% | China | E-REI (CAN), VAC (GER) |
| Lithium Hydroxide | ~70% | <60% | China | Albemarle (USA), SQM (AUS/CHL) |
| Class 1 Nickel | ~45% | <60% | Russia/Indonesia | Vale (CAN), BHP (AUS) |
| Cobalt (Refined) | ~75% | <60% | China (DRC Origin) | Jervois (USA), Glencore (NOR) |

The Role of the Circular Economy
The 60% rule cannot be achieved through new mining alone. The G7 has set a secondary target: recycling must account for at least 20% of annual critical mineral consumption by 2035.
By treating "urban mines" (electronic waste and spent batteries) as strategic reserves, the G7 aims to reduce the total volume of raw material that needs to be imported. This shift is already changing the mining operations landscape, as traditional mining majors like Rio Tinto and Glencore invest heavily in black mass processing and hydrometallurgical recycling facilities.
Operational Challenges and the "ESG Premium"
The "Firewall" strategy is not without risks. For operators, the biggest challenge is the speed of permitting. While the U.S. Inflation Reduction Act (IRA) and the EU Critical Raw Materials Act have provided capital, the actual timeline to bring a mine from discovery to production remains 10 to 15 years in most G7 nations.
Furthermore, the focus on ESG (Environmental, Social, and Governance) standards creates a paradox. The G7 requires "clean" minerals, but the very regulations that ensure cleanliness often delay the projects needed to meet the 60% diversification target. Industry leaders are calling for "Permitting Reform" as the necessary corollary to the 60% rule. Without it, the firewall may be a policy without a foundation.
Looking Ahead: 2026-2030
As we move toward 2030, the mining industry will likely see a permanent two-tier market. There will be the "Global Market," driven by price and dominated by incumbent players, and the "Security Market," driven by G7 mandates and characterized by higher prices, stricter ESG compliance, and government-backed stability.
For investors, the opportunity lies in identifying projects that "check the boxes" for the G7 Alliance: located in friendly jurisdictions, possessing a clear path to mid-stream processing, and adhering to the highest environmental standards. As the copper supply forecast already shows in the energy sector, demand is decoupling from traditional cycles and re-anchoring to geopolitical necessity.
The 60% rule is more than a trade quota; it is a declaration of industrial independence. For the global mining community, the message is clear: the source of your mineral is now just as important as the mineral itself.

The G7 has officially launched the "60% Rule" for critical minerals. By 2030, no single external supplier can provide more than 60% of high-priority imports like REEs and Lithium. This "Firewall" is reshaping mining finance and forcing a massive shift toward "friend-shoring." Is the mining industry ready for a bifurcated global market?
