Critical Minerals

The raw materials of the electric age: what they are, why demand is exploding, and how one country came to refine most of them.

The old economy ran on hydrocarbons. The new one runs on lithium, copper and rare earths, and the map of power is being redrawn accordingly. Energy security used to mean oil tankers; increasingly it means refineries, magnets and mines.

August 2026

Copper hit records and the supply squeeze tightened

  • Mining Reporters (11 Aug 2026): Comex copper touched $6.7005/lb, 0.4 cents under the $6.7045/lb record set on 5 Aug; LME three-month copper was about $14,195.50/t. Copper was up nearly 18% in 2026 and had roughly doubled over 12 months.
  • The Gresik smelter that processes Grasberg ore was suspended after a boiler leak on 8 Aug; Grasberg itself is still recovering from the September 2025 mudslide and is not targeted to reach full production until end-2027.
  • LME copper warehouse stocks fell 4,675 t to 218,300 t.
July 2026

The IEA's 2026 outlook says concentration and weak investment are the risk

  • The IEA released its Global Critical Minerals Outlook 2026 on 16 July 2026, headlined: supply concentration, export restrictions and declining investment put critical mineral security at risk.
  • IEA reported that prices rebounded in 2025 and early 2026 after years of decline, investment fell 9% in 2025, and refining concentration rose for most minerals (via press coverage of the report).
  • As summarised by Skillings Mining (18 Jul 2026, not verified against the IEA text): lithium demand growth to 2040 of eightfold, a copper structural deficit of about 25% through 2035, and $6.5 trillion of downstream output at risk by 2030 from expanded Chinese controls on gallium, germanium and graphite.
November 2025 to November 2026

China's expanded rare-earth controls are paused, not scrapped

  • After the Trump-Xi meeting in South Korea, China suspended its 9 Oct 2025 expansion of rare-earth export controls for one year, to 10 Nov 2026 (Mining.com and Mining Technology, 27 Apr 2026).
  • The April 2025 licensing regime for seven medium and heavy rare earths (samarium, gadolinium, terbium, dysprosium, lutetium, scandium, yttrium) and related magnets stays in force (Mining Technology, 27 Apr 2026).
  • GlobalData (2025 figures): China produced 270 kt of about 390 kt REO-equivalent mined (69.2%) and processes up to 90% of rare earths. No confirmed extension beyond 10 Nov 2026 was found.
May to October 2026

Lithium rebounded sharply in 2026 before easing

Reported futures data (Reuters via secondary outlets): the most active Guangzhou lithium carbonate contract closed near 104,740 yuan/t on 12 Oct 2026, about half the 209,880 yuan peak of 13 May 2026, yet above year-earlier levels. The 80% crash of 2022-2025 has therefore been partly reversed, which does not change the structural argument about supply timelines.

February 2026

Washington moved to stockpiling and price support

Project Vault, a roughly $12 billion US strategic critical-minerals reserve (about $10 billion EXIM financing plus about $2 billion private capital, per law-firm analyses), was announced in early February 2026. Separately, the Pentagon's equity stake in MP Materials is reported to include a $110/kg NdPr price floor. Commerce's Section 232 critical-minerals review found heavy reliance on imported processed minerals threatens national security (reported conclusion 24 Oct 2025); reports say broader price-floor plans may be scaled back.

Not refreshed: current refining-share percentages (kept at 2025 values), EU Critical Raw Materials Act progress, battery gigafactory count, ore-grade and recycling figures, 2030-2035 copper supply-demand chart values, and the late-October 2026 lithium and copper spot prices.

Test yourself

Lithium carbonate futures fell from about 209,880 to about 104,700 yuan/t. What does the chapter conclude?

What is the status of China's October 2025 rare-earth export expansion?

What They Are

The periodic table of power

Orientation

How to read this deck

  • Minerals are the transition's fuel. Every EV, panel and data centre starts as rock.
  • Mining is not refining. The geology is spread worldwide; the processing is not. That gap is the story.
  • Every number is sourced. Demand curves and shares from the IEA and USGS, dated.
  • Prices deceive. Boom-bust cycles hide the structural squeeze underneath.

The cast

Six minerals that run the modern world

ItemDescription
LithiumThe irreplaceable heart of every EV and grid battery.
CopperThe metal of electrification: wires, motors, grids.
Rare earthsTiny magnets in every motor, turbine and missile.
Nickel & cobaltBattery cathodes: energy density in metal form.
GraphiteEvery lithium battery's anode; four-fifths from China.
Silicon & polysiliconThe substrate of chips and solar alike.

A critical mineral is not a rare one. It is a mineral the economy cannot pause without, supplied through a door one hand can close.

Criticality = importance x concentration. Neither alone earns the name.

The journey

From rock to product, in four stages

  1. Ore is extracted: years of permits, decades of capex.
  2. Raw ore becomes battery- or magnet-grade material.
  3. Materials become cathodes, magnets, components.
  4. Components become EVs, turbines, electronics.
Mineral intensity

Clean tech is materials-hungry

15-20 yearsAverage time from mineral discovery to producing minePermitting, financing, construction and ramp-up

Demand that doubles in five years is being served by supply that takes fifteen to respond: the structural mismatch behind every price spike.

The criticality map

Supply risk versus economic importance

A quadrant map of supply risk (vertical) against economic importance (horizontal), with quadrants labelled Niche worries, The danger zone, Comfortable and Watch closely. Rare earths, graphite, cobalt and lithium sit in the danger zone (top right), with rare earths and graphite highest on supply risk. Nickel sits near the midline and copper sits far right but lower on supply risk. Aluminium sits lower right, in the watch-closely quadrant.

Source: analysis after EU/US criticality frameworks.

The politics

Minerals became weapons in slow motion

  1. First shot: China halts rare earths to Japan.
  2. IRA: America subsidises its own chain.
  3. Gallium & germanium: China restricts chip metals.
  4. Graphite controls: battery anodes join the list.
  5. Rare-earth squeeze: automakers face stoppages; Oct 2025 expansion paused to 10 Nov 2026.

Data centresAI's build-out is copper- and power-hungry.
DefenceRare-earth magnets in everything that flies or guides.
ElectronicsThe baseline demand that never went away.
The whipsaw

Lithium's boom-bust hides the structural story

A line chart of a lithium price index (2020 = 100) from 2020 to 2025: the price rises to an 8x spike in 2022, then falls more than 80% by 2024-2025. Prices then rebounded in 2026 (see What has changed).

Source: Industry price indices (2020-25).

The lithium crash didn't cancel the shortage: it caused the next one, by starving the mines that 2030 will need.

Low prices today cancel projects that take a decade to build. The bust plants the seeds of the boom.

400+Battery gigafactories announced or built worldwide

Each needs a supply chain of lithium, nickel, graphite and copper locked years in advance. The factories are the easy half; the feedstock contracts behind them are where the real competition happens.

Test yourself

Per the chart, which statement about demand growth to 2040 is correct?

Why does the chapter say the lithium crash 'caused the next shortage'?

Every EV motor, wind turbine and precision missile needs them. When Beijing restricted exports in 2025 (the October expansion is paused until 10 November 2026), automakers faced production halts within weeks: a live demonstration of what leverage means.

How it happened

The two-decade playbook

  • Tolerate the mess. Refining is dirty; China accepted the environmental cost others outsourced.
  • Subsidise the scale. Cheap credit and power made Chinese processing unbeatable.
  • Price out rivals. Zero-fee smelting today buys monopoly tomorrow.
  • Integrate downstream. Refining fed batteries fed EVs: the whole chain, in-house.

Test yourself

A copper mine costs $2B and takes 15-20 years to reach production. What is the chapter's explanation for weak investment?

Indonesia is now a nickel powerhouse. Why is this only partial diversification?

05

The Copper Problem

The metal with no substitute

Everything in the electric age (every wire, motor, grid and data centre) needs copper. And copper is quietly running short.

Lithium gets the headlines; copper carries the current. Its gap is the harder one to close.

The gap

Where the copper goes

Every megatrend pulls the same metal

ItemDescription
The gridWires, transformers, substations: the biggest single pull.
EVs~80 kg per car, 4x a petrol vehicle.
Data centresPower distribution and cooling, at AI scale.
RenewablesSolar farms and especially offshore wind.
ConstructionThe old demand that never left.
Defence & industryEverything electric, everywhere.

If lithium is the transition's headline, copper is its bloodstream: invisible, everywhere, and much harder to replace.

Chemistries can route around cobalt or nickel. Nothing routes around conductivity.

Test yourself

From the chart, what is the 2035 gap between demand and mine supply as a share of demand?

Why is copper described as harder to substitute than cobalt or nickel?

Risks & Responses

The honest chapter

Both sides, fairly

Crisis narrative versus market faith

The crisis caseThe market case
1Concentration: one country, most refiningPrices work: spikes summon supply, eventually
2Timelines: supply can't chase demandInnovation: chemistries shift around scarcity
3Copper: a genuine geological squeezeRecycling: the ore pile grows every year
4Weaponisation: already demonstratedDemand flex: substitution and efficiency respond
The risk register

Six risks a serious observer tracks

ItemDescription
Export weaponisationRare-earth-style controls spreading to other minerals.
Copper deficitThe one gap that touches everything.
Project slaughterLow prices killing the 2030s' supply today.
Resource nationalismProducer countries rewriting terms mid-game.
ESG collisionsMines the transition needs, communities reject.
Chokepoint chemistryRefining know-how harder to copy than assumed.
The response toolkit

What the West is actually doing

  • Subsidise. IRA credits and EU acts pull mines and refineries onshore.
  • Stockpile. Strategic reserves for magnets and battery metals.
  • Diversify. Friend-shoring deals across Australia, Africa, the Americas.
  • Substitute & recycle. Sodium batteries, magnet-free motors, urban mining.

What to Watch

Signposts, not predictions

The dashboard

Four dials worth watching

Cu deficitCopper balancethe master variable
Export rulesChina policyleverage in action
Ex-China %New refiningdiversification, real or paper
Project FIDsInvestmentthe 2030s being funded, or not
Key takeaways

Five signposts for the next 24 months

  1. Does China escalate export controls? Each round accelerates the West's response.
  2. Do copper projects get funded? FIDs now decide the 2035 balance.
  3. Does ex-China refining scale? The only structural fix that matters.
  4. Do new chemistries dent demand? Sodium and LFP shift the lithium curve.
  5. Does recycling industrialise? Urban mining moving from pilot to plant.
Key takeaways

The five conclusions to take away

  1. A materials dependency replaces a fuel one: the trade is good; the transition is exposed.
  2. Refining beats mining: control of chemistry outranks control of rock.
  3. Copper is the master constraint: watch it above everything.
  4. Cycles mask structure: price crashes fund tomorrow's shortages.
  5. The 2020s are the gap years: insurance is being bought for a decade away.
