The Strategic Independence Race. They are not actually rare — but China controls 60% of the mining and 90% of the processing. The West is a decade behind. This is the most geopolitically charged shortage on the board.
Building mine-to-magnet supply chains outside China requires a minimum of 7-10 years. No shortcuts exist for permitting, processing R&D, and workforce training.
Beijing's July 2023 gallium/germanium export ban and 2024 antimony restrictions confirm the weaponization trend. The West is reacting, but slowly.
The critical distinction most investors miss: China does not merely mine rare earths — it processes them. Even minerals mined in Australia, Myanmar, or the US are shipped to China for separation and refining. This mid-stream chokepoint is far more dangerous than the upstream mining share, because building a processing plant requires specialized chemical engineering, billions of dollars, and 5-7 years of regulatory approval. The chart below illustrates the gap between mining and processing dominance.

The name "rare earths" is misleading. Cerium is as abundant as copper in the earth's crust. Neodymium is more common than tin. The problem is not geological scarcity — it is concentration and chemistry. Rare earth elements almost never occur in concentrated deposits. They are dispersed across vast rock formations, mixed together, and chemically bonded in ways that make separation extraordinarily difficult.
Separating neodymium from praseodymium, for instance, requires thousands of stages of solvent extraction using hydrochloric acid, kerosene, and other toxic chemicals. Each stage yields tiny incremental purity improvements. The entire process generates vast quantities of radioactive thorium waste. China was willing to absorb the environmental cost for decades. The West was not. Now, rebuilding that capability from scratch is a generation-long project.
The table below maps the minerals at the heart of the energy transition and defense supply chains. Each one represents a different flavor of supply risk — some are geographically concentrated, others depend on a single processing country, and a few face both problems simultaneously.
| Mineral | Primary Demand Driver | Top Mining Country | China Processing % | Price Trend (2024-26) | Supply Risk |
|---|---|---|---|---|---|
| Neodymium (NdPr) | EV motors, wind turbines, defense | China (60%), Myanmar (12%) | 90% | Volatile ↑ | Critical |
| Lithium | EV batteries (LFP & NMC) | Australia (47%), Chile (26%) | 65% | Recovering ↑ | High |
| Cobalt | EV batteries (NMC cathodes) | DRC (70%), Indonesia (5%) | 75% | Stable | Critical |
| Gallium | Semiconductors (GaN), 5G, defense radar | China (98%) | 98% | Export Ban ↑↑ | Extreme |
| Germanium | Fiber optics, night vision, satellites | China (60%), Canada (15%) | 80% | Export Ban ↑↑ | Extreme |
| Graphite | Battery anodes (100% of Li-ion) | China (65%), Mozambique (12%) | 90% | Stable | Critical |
| Antimony | Ammunition, flame retardants, solar | China (48%), Tajikistan (25%) | 85% | Export Ban ↑↑ | Extreme |
| Manganese | Steel alloys, LFP battery cathodes | South Africa (37%), Gabon (18%) | 55% | Rising ↑ | Moderate |

Most media coverage focuses on mining. This is the wrong lens. The real chokepoint is mid-stream processing — the transformation of raw ore into battery-grade or magnet-grade materials. Consider: Australia mines 47% of the world's lithium, but ships nearly all of it to China for conversion into lithium hydroxide. The DRC extracts 70% of global cobalt, but 80% is processed in Chinese-owned refineries.
The processing gap exists because these facilities require: (1) billions of dollars in capital, (2) specialized chemical engineering expertise concentrated in a few hundred people globally, (3) 3-5 years of permitting in Western jurisdictions, and (4) communities willing to accept a chemical plant nearby. China built its processing dominance over 30 years of state-directed investment. The US Inflation Reduction Act (2022) and EU Critical Raw Materials Act (2023) are the first serious responses — but they are at least a decade behind.
NdPr oxide is the indispensable ingredient in permanent magnets. Every EV traction motor uses 1-2 kg. Every offshore wind turbine uses 600+ kg. Every F-35 fighter jet uses over 400 kg. Demand is on a structural exponential trajectory while new mine supply struggles with 7-10 year lead times. The deficit, currently modest, becomes acute by 2028-2030.

The geopolitical awakening came in stages: first, China's 2010 rare earth embargo against Japan. Then, COVID-19 exposed pharmaceutical supply chains. Finally, Russia's invasion of Ukraine made energy sovereignty an existential concern. The policy response is now massive — but execution will take years.

In July 2023, Beijing imposed export controls on gallium and germanium — two metals essential for semiconductors, fiber optics, night vision systems, and satellite communications. This was widely interpreted as a direct response to US/Dutch chip export restrictions on ASML and Applied Materials equipment. In October 2024, antimony restrictions followed. The pattern is clear: China is systematically weaponizing its mineral dominance as a countermove in the tech war.
| Mineral | Pre-Ban Price | Post-Ban Price | Change | Key End-Use at Risk |
|---|---|---|---|---|
| Gallium | $300/kg | $900+/kg | +200% | GaN semiconductors, 5G, defense radar |
| Germanium | $1,200/kg | $2,800+/kg | +130% | Night vision, IR optics, fiber optic cables |
| Antimony | $12,000/t | $38,000+/t | +215% | Ammunition primers, flame retardants |
When prices spike, the market's first instinct is to ask: "Can we substitute?" The answer is almost always "yes, eventually" but the timeline matters enormously for investors. NdFeB (neodymium-iron-boron) permanent magnets have no comparable substitute for high-performance applications. Ferrite magnets exist, but they produce 60-70% less torque per kilogram — meaning EV motors would need to be significantly larger and heavier. Tesla has been developing a permanent-magnet-free motor since 2023, but even their internal timeline targets 2028+ for production.
For lithium, sodium-ion batteries are emerging as a partial substitute for stationary storage and low-range EVs, but they remain 15-20% less energy-dense and require entirely new manufacturing lines. For cobalt, the shift to LFP (lithium iron phosphate) chemistry has reduced demand in Chinese EVs, but Western OEMs (BMW, Mercedes) still rely on NMC (nickel-manganese-cobalt) for range. Substitution is not a switch you flip — it is a 5-10 year capital investment cycle.
Every modern weapons system depends on rare earth permanent magnets. The F-35 Lightning II uses over 920 lbs of rare earth materials. An Arleigh Burke-class destroyer requires 5,200 lbs. A Virginia-class nuclear submarine uses 9,200 lbs. Precision-guided munitions, satellite communications, night vision goggles, and radar systems all require gallium, germanium, or rare earth magnets. The US Department of Defense has identified 14 critical minerals for which it has zero domestic processing capability.
This creates a paradoxical situation: the US military, the most powerful fighting force in history, depends on its primary strategic competitor for the materials needed to build its weapons. In a Taiwan contingency scenario, China could simultaneously restrict rare earth exports and force the US to choose between building F-35s and building electric vehicles. This is not a theoretical concern — it is the explicit rationale behind the Defense Production Act Title III investments.
| Weapons System | Rare Earth Content | Key Materials | China Dependence | Substitute Available? |
|---|---|---|---|---|
| F-35 Lightning II | 920 lbs (417 kg) | NdFeB magnets, samarium cobalt | ~95% | No |
| Virginia-class Submarine | 9,200 lbs (4,173 kg) | NdFeB magnets, terbium, dysprosium | ~90% | No |
| DDG-51 Destroyer | 5,200 lbs (2,359 kg) | NdFeB, samarium cobalt, gallium | ~90% | No |
| Javelin Missile | ~1 lb (0.5 kg) | NdFeB (guidance), germanium (seeker) | ~85% | Partial (degraded performance) |
| JDAM (Guided Bomb) | ~0.5 lb (0.2 kg) | NdFeB (fin actuators), samarium | ~85% | Partial |
| Night Vision (AN/PVS-31) | Trace (germanium lenses) | Germanium, gallium arsenide | ~80% | No |

Defense spending on critical mineral supply chains is bipartisan and durable. Both Republican and Democratic administrations have increased funding for domestic rare earth processing. The FY2025 NDAA (National Defense Authorization Act) includes $1.2B in additional critical minerals provisions. This creates a government-guaranteed demand floor for companies like MP Materials and Lynas that are building non-China supply chains. Unlike commercial EV demand (which can cycle), defense procurement is multi-year and contract-backed.
While primary mining will remain the dominant source of critical minerals through 2035, a nascent recycling industry is emerging. The EU Critical Raw Materials Act mandates 25% recycling targets by 2030. The challenge is enormous: current rare earth recycling rates are below 1% for NdFeB magnets and below 5% for lithium-ion batteries.
The economics are improving. A discarded EV battery pack contains $1,500-3,000 worth of lithium, cobalt, nickel, and manganese at current prices. A decommissioned wind turbine contains 600+ kg of NdPr magnets worth $30,000+. The problem is collection and processing infrastructure — there is no established reverse logistics network, and the chemical separation processes are still being refined at laboratory scale.
Companies to watch in recycling: Li-Cycle (LICY) — lithium-ion battery recycling with hydrometallurgical process, but struggling with Rochester Hub delays and cash burn. Redwood Materials (private, JB Straubel's startup) — backed by Amazon, Toyota, building the largest US battery recycling plant in Nevada. Urban Mining Company — NdFeB magnet recycling using hydrogen decrepitation, pre-commercial. These are not yet investable at the core portfolio level, but they represent the long-term supply solution and potential acquisition targets for majors.
Understanding where value is created (and where it is captured by China) requires mapping the full supply chain. Each stage adds value and increases China's control percentage. The West's current strategy is to build each stage domestically, but the effort is staggered: mining is furthest along, separation is in progress, and magnet manufacturing is barely beginning.
Notice how China's dominance increases at each stage of the value chain. It is 60% at the mine but 92% at the magnet. This means that even if the West succeeds in building new mines, it will still be dependent on Chinese processing for years. The true "chokepoint" is stages 2-4 — separation, metal making, and magnet manufacturing. This is exactly where MP Materials' Fort Worth facility and Lynas' Kalgoorlie plant are targeting. The investment thesis is about moving from 60% dependency (mining) toward reducing the 90%+ dependency (processing).
The investable universe in critical minerals is small, illiquid, and volatile. This is a feature, not a bug — it means the market is still mispricing the structural shift. We focus on companies with real assets, real production (or near-term production), and strategic government backing.
Thesis: Owns Mountain Pass, California — the only integrated rare earth mine in North America. Revenue $185M (2024). The company is vertically integrating downstream: its Fort Worth, Texas magnetics facility is targeting commercial production of NdFeB magnets by late 2026. GM has a $700M offtake agreement. The US Department of Defense awarded a $58.5M grant for heavy rare earth separation. MP is essentially a government-backed national champion with no domestic competitor.
Key risk: NdPr oxide price collapse if China dumps inventory to undercut Western competitors (as it did in 2015-2020).
Thesis: Australian-listed, operates the Mt Weld mine (Western Australia) and the only large-scale rare earth processing plant outside China (LAMP facility, Malaysia). Revenue A$710M (FY2024). Building a A$500M processing plant in Kalgoorlie, WA to reduce Malaysian dependency. Awarded a $258M US DoD contract for a heavy rare earth separation facility in Texas. The only company globally with a diversified, non-China refining footprint at scale.
Key risk: Malaysian license renewal (political risk). Kalgoorlie plant delays. NdPr price volatility.
Thesis: Developing Thacker Pass in Nevada — the largest known lithium resource in North America and one of the largest in the world. Received a $2.26B DOE loan commitment. GM invested $650M. Phase 1 production expected late 2027, targeting 40,000 tpa lithium carbonate equivalent. This is a pre-revenue, construction-phase company with binary risk: if Thacker Pass delivers on time, LAC reprices dramatically; if delays or cost overruns occur, the equity gets diluted.
Key risk: Pre-revenue. Construction delays. Lithium price floor uncertainty ($12-15k/t breakeven assumption).
For investors who want exposure without single-stock risk, two ETFs provide broad critical minerals coverage:
AUM: $300M. Top holdings: Zhejiang Huayou Cobalt, Pilbara Minerals, Lynas, MP Materials. Expense ratio: 0.54%. Heavy China weight (~40%).
AUM: $1.6B. Top holdings: Albemarle, TDK, BYD, Samsung SDI. Expense ratio: 0.75%. More battery value chain, less pure mining.
Beijing has a proven playbook: flood the market with cheap material to destroy nascent Western competitors, then re-establish monopoly pricing once rivals go bankrupt. This happened with rare earths in 2015-2020, with solar panels (2012-2018), and with steel (ongoing). If NdPr oxide falls below $40/kg for 18+ months, most Western mining projects become uneconomic. Mitigant: Defense Production Act stockpile purchases and IRA tax credits provide a price floor that did not exist in 2015. Political will to maintain domestic supply is structurally higher post-Ukraine.
The EV industry is actively researching permanent-magnet-free motors. Tesla's next-generation platform reportedly uses a switched reluctance motor that eliminates NdFeB magnets entirely. If this technology scales successfully and other OEMs follow, NdPr demand from EVs (~35% of total) could plateau. Mitigant: Wind turbines, defense, and industrial applications still require permanent magnets. Even a successful motor substitution would only flatten the demand curve, not collapse it.
Urban mining — recovering rare earths from discarded electronics, EV batteries, and wind turbines — is theoretically attractive but practically challenging. Current NdFeB magnet recycling rates are below 5% globally. Startups like Urban Mining Company and REEtec are developing hydrometallurgical processes, but commercial scale is 2028+ at the earliest. Mitigant: Even aggressive recycling scenarios (20% recovery by 2035) would only reduce, not eliminate, the primary supply deficit.
70% of the world's cobalt comes from the Democratic Republic of Congo — a country with chronic instability, artisanal mining practices that involve child labor, and infrastructure that can collapse during rainy seasons. In 2018, cobalt prices surged to $95,000/tonne as EV hype peaked, then crashed to $25,000 as DRC production surged and battery chemists shifted to lower-cobalt formulations (NMC 811, LFP).
The lesson for rare earth investors: geographic concentration creates binary outcomes. When supply is disrupted (coup, export ban, mine accident), prices spike violently. When supply normalizes, they can crash just as fast. This is why position sizing and stop-losses are non-negotiable in critical minerals investing. Never size a single mining stock above 3-4% of a portfolio.
Critical minerals are high-conviction, high-volatility assets. The right approach is barbell sizing: a core position in the highest-quality name (MP Materials or Lynas, 3-4% of portfolio) combined with a smaller speculative allocation (LAC or a junior miner, 1-2%) and a diversified ETF sleeve (REMX/LIT, 2-3%). Total critical minerals exposure should not exceed 6-8% of a diversified portfolio.
Entry should be staggered over 3-6 months using dollar-cost averaging, because commodity prices are inherently volatile and timing the bottom is impossible. Use NdPr oxide prices (tracked by Asian Metal, Shanghai Metals Market) as a leading indicator: when NdPr oxide stabilizes above $70/kg and trending upward, the miners will follow with a 2-4 week lag.
