Highlights

  • UK’s 34-mineral list and EU CRMA are reshaping funding, permitting, and supply-chain priorities for battery metals and rare earths.
  • FTSE investors can combine diversified majors with AIM-listed developers for exposure to lithium, tin, graphite, and rare earth growth themes.
  • 2025 catalysts include Cornish tin restart, European spodumene project approvals, and UK lithium refinery FID milestones.

In 2024, the UK’s Critical Minerals Intelligence Centre (CMIC) published an updated national assessment identifying 34 minerals as “critical.” These are essential to the economy, face supply chain risk, and are difficult to substitute. The list includes lithium, nickel, cobalt, manganese, graphite, magnet rare earths (NdPr, Dy, Tb), vanadium, tungsten, and tin.

This classification is more than academic. It guides policy support, public funding, and international partnerships. For investors, that means projects aligned with the list may enjoy permitting advantages, R&D support, and financing initiatives — all of which can accelerate timelines. Interestingly, copper is not classified as critical in the UK, despite its centrality to electrification. This explains why copper supply is mostly left to market forces, while battery metals, rare earths, and tin/tungsten receive direct industrial policy attention.

The UK government has backed its words with money, including funding to revive Cornish tin production — a symbolic step towards reshoring critical mineral supply. The EU’s Critical Raw Materials Act (CRMA) adds another layer of support for UK-listed companies with projects in Europe, granting “strategic” projects permitting and financing tailwinds.

The FTSE Landscape – Two Worlds of Exposure

FTSE-listed critical minerals stocks broadly split into two buckets:

Main Market Diversified Majors

  • Glencore (GLEN): A cobalt and nickel powerhouse with global mining, trading, and recycling operations, giving investors direct exposure to battery metals.
  • Anglo American (AAL): Exposure to nickel, PGMs, and copper, though 2025 saw portfolio reshaping including a move to sell down nickel assets after a brutal price slump.
  • Rio Tinto (RIO): Owner of the Rincon lithium project in Argentina and multiple critical-material adjacencies, offering long-term optionality.

These names provide liquidity, balance sheet strength, and diversified exposure across commodities.

AIM-Listed Developers & Midstream Plays
AIM hosts the pre-production companies trying to build tomorrow’s supply:

  • Lithium: Atlantic Lithium (Ghana), Savannah (Portugal), European Metals (Czech Republic), Alkemy/TVL (UK refining).
  • Rare Earths: Pensana (Angola + UK processing), Rainbow Rare Earths (South Africa), Mkango/HyProMag (UK magnet recycling).
  • Graphite: Tirupati (Madagascar), Blencowe (Uganda), Sovereign Metals (Malawi; rutile + graphite).
  • Tin/Tungsten: Cornish Metals (Cornwall), Tungsten West (Devon), First Tin (Australia/Germany).
  • Vanadium: Ferro-Alloy Resources (Kazakhstan).

These stocks are more volatile, sensitive to permitting, funding, and commodity cycles — but they also offer the highest leverage when sentiment and prices turn.

Lithium – Riding Out the Cycle

Lithium prices collapsed through 2024 after peaking in 2021–22, as supply from Australia and China met weaker-than-expected EV demand. For FTSE lithium names, this price slump forced capex discipline and delayed some development timelines.

Key FTSE lithium exposures:

  • Atlantic Lithium (AIM: ALL): Ewoyaa in Ghana could be West Africa’s first spodumene mine. Mining lease granted, but fiscal terms and project financing remain key hurdles.
  • Savannah Resources (AIM: SAV): Barroso (Portugal) is Europe’s largest spodumene deposit and a CRMA-designated Strategic Project. Licences and DFS progress are catalysts, though permitting challenges remain.
  • European Metals (AIM: EMH): Cinovec (Czech Republic) is backed by ČEZ, the state utility. DFS funding milestones in 2025 are critical to advance this EU cornerstone project.
  • Alkemy Capital (LSE: ALK): Tees Valley Lithium (TVL) aims to be Europe’s largest independent lithium hydroxide refinery. 2025 saw a binding feedstock deal and FEED progress — FID is the next inflection point.

Rare Earths – From Mines to Magnets

Rare earth prices softened in 2023–24 but may tighten in 2025 as EV and wind turbine demand improve. This could be decisive for financing new projects.

Names to watch:

  • Pensana (LSE: PRE): Developing an Angola-UK mine-to-magnet vision; MoU with ReElement signals serious midstream ambitions.
  • Rainbow Rare Earths (AIM: RBW): Phalaborwa project aims to extract REEs from phosphogypsum, offering a low-cost, secondary-feedstock route to market.
  • Mkango/HyProMag (AIM: MKA): Leading the UK’s magnet recycling charge. First recycled alloy production in 2025 is a milestone for circular economy supply chains.

Graphite – Diversifying Beyond China

Graphite is essential for lithium-ion anodes, and China’s dominance in processing has made diversification a policy priority.

  • Tirupati (AIM: TGR): Madagascar operations are restarting after corporate restructuring; governance and funding stability remain key watchpoints.
  • Blencowe (AIM: BRES): Orom-Cross DFS completed, scale potential confirmed. Financing and offtake deals are the next steps.
  • Sovereign Metals (AIM: SVML): Kasiya is the world’s largest natural rutile deposit and second-largest flake graphite deposit — with Rio Tinto as a technical partner, giving credibility.

Tin & Tungsten – The UK’s Comeback Metals

Tin demand remains robust thanks to its role in solder and semiconductors, while tungsten is a defence-critical metal with constrained supply.

  • Cornish Metals (AIM: CUSN): Received ~£29m government investment to restart South Crofty, a historic UK tin mine.
  • Tungsten West (AIM: TUN): Hemerdon has Strategic Project status under CRMA, updated feasibility work complete, financing next.
  • First Tin (LSE: 1SN): Taronga DFS complete, advancing approvals work in Australia and Germany.

Vanadium – Energy Storage Play with Risks

  • Ferro-Alloy Resources (LSE: FAR): Balasausqandiq project advancing toward feasibility with a low-cost target. If financed, could serve both steel and battery markets.
  • Bushveld Minerals (AIM: BMN): Delisted and liquidated in 2025 — a cautionary tale that “strategic” status does not guarantee survival without a viable capital structure.

Alternative Plays – Royalties & Midstream

Investors seeking less operational risk can explore Ecora Resources (LSE: ECOR) for nickel/cobalt royalty exposure, or midstream plays like HyProMag and TVL, which provide leverage to processing margins and supply-chain localisation rather than pure mining risk.

Macro and Policy Context

Lithium oversupply, nickel surpluses from Indonesia, and weak prices have challenged funding plans, while rare earths may see tightening into 2025. Policy remains a strong driver — EU and UK strategic designations can accelerate permits and unlock financing.

Investor Framework

A practical approach to building exposure:

  • Anchor with a major like Glencore or Rio Tinto for liquidity and downside protection.
  • Add 2–4 AIM developers across lithium, REE, graphite, and tin for upside torque.
  • Monitor catalysts — DFS completions, permits, financing packages, and government funding.
  • Diversify across minerals to smooth out commodity-specific volatility.

Critical minerals remain one of the most strategically significant themes for the next decade, but not all stocks will win. The FTSE offers investors a spectrum — from globally diversified majors to high-torque AIM juniors. The best portfolios balance near-term catalysts with long-term structural exposure, mix operating cash flows with project development optionality, and stay alert to the interplay between policy, pricing, and permits.
