Highlights

  • Demand for critical minerals such as lithium, copper, rare earths, and cobalt is surging as transport electrification, green energy, and supply chain security become top priorities for governments and industries.
  • London remains a central hub for accessing diversified global mineral supply through its major mining companies, specialist developers, and transparent market infrastructure.
  • Policy momentum in allied nations is supporting non-China mineral supply chains, faster financing, and ESG standards, driving investment and innovation across the UK’s critical minerals ecosystem.

The global drive to electrify transport, decarbonize power, and harden supply chains against single-country concentration has turned a cluster of commodities into strategic inputs: lithium, nickel, cobalt, copper, graphite, rare earths, uranium, vanadium, tin, titanium feedstocks and iodine (for catalysts, pharmaceuticals, and specialty chemicals). London’s markets remain a gateway to globally diversified exposure:
Diversified majors (Rio Tinto, Anglo American, Glencore, Antofagasta) tie you to copper and battery metals at scale.
Specialists and developers (Pensana, Rainbow Rare Earths, Atlantic Lithium, Cornish Metals, Kenmare Resources, Yellow Cake) give leverage to rare earth magnets, EV anodes, domestic tin revival, titanium feedstocks and uranium inventories.
Policy signals are increasingly explicit: allied governments want diversified, transparent, ESG-audited supply chains. That translates into cheaper project finance, export-credit backing, and faster customer qualification for non-China supply in magnets (NdPr, Dy/Tb), batteries (lithium/graphite), and nuclear fuel (U₃O₈). Against that backdrop, here are ten names to know.

  1. Rio Tinto (LSE:RIO): from copper backbone to a distinct lithium arm
    Where it fits: One of the world’s mining majors—and now building a dedicated lithium business alongside its copper core. Rio’s Rincon brine project in Argentina is slated for a multi-decade life, with construction of the expanded plant discussed for mid-2025 (permitting dependent) and first production targeted later in the decade; the company has also pursued lithium growth via M&A and Chilean JV investments.
    Why it matters:
    Lithium remains central to EV batteries; tier-1 operators with balance-sheet depth can build low-cost, long-life projects and ride out price cycles.
    Copper is the grid metal—motors, transmission, renewables—all roads lead to copper, and Rio maintains scale exposure through multiple districts (complementing its lithium pivot).
    Key near-term watch-items
    Rincon execution milestones (EPC, ponds/plant integration, power and water balance) and permitting clarity.
    Integration of lithium assets and leadership structure under Rio Tinto Lithium post-transaction.
    Any Chile lithium JV advancements (e.g., Maricunga) that signal policy-aligned growth.
    Risks: Lithium price cyclicality; brine ramp timing; social-license complexity in South America.
  2. Anglo American (LSE:AAL): simplifying around copper (and letting go of nickel/PGMs)
    Where it fits: Anglo is reshaping its portfolio to focus on copper and premium iron ore, slimming down exposures that don’t fit the strategy. In 2025, management advanced a demerger of its platinum unit and agreed to sell the nickel business, while reporting a copper-led operational performance.
    Why it matters:
    Copper is the secular core for the electrification build-out. Anglo’s simplification should make the investment case clearer and the capital allocation more transparent.
    Disposals (nickel) reduce noise and fund the growth pipeline.
    Key near-term watch-items
    Progress on the PGM demerger and nickel sale closing; proceeds and balance-sheet implications.
    Copper unit cost and grade trends in H2/FY reports.
    Risks: Execution risk on portfolio changes; commodity price whipsaw (diamonds/PGMs) until fully separated.
  3. Glencore (LSE:GLEN): copper-cobalt-nickel scale plus a real recycling engine
    Where it fits: A global mining/marketing powerhouse and one of the largest producers of copper, cobalt and nickel—with an increasingly important recycling franchise spanning electronics and lithium-ion batteries.
    Why it matters:
    Cobalt (by-product of copper) and nickel are critical for many battery chemistries; Glencore’s DRC and Canadian footprints provide market-moving supply.
    The marketing arm arbitrages physical markets, while recycling helps close the loop and derisk ESG narratives on critical metals.
    Key near-term watch-items
    Copper/cobalt production guidance vs. market balances.
    Expansion of battery-recycling partnerships and throughput.
    Risks: DRC jurisdictional risk; commodity price beta; counterparty risks in trading.
  4. Antofagasta (LSE:ANTO): copper pure-play with water-security projects on schedule
    Where it fits: A FTSE-100 copper pure-play with assets concentrated in Chile. The company is progressing major growth and resilience projects—Centinela expansion (second concentrator) and Los Pelambres desalination/water pipeline upgrades—aimed at increasing ore throughput while derisking climate-sensitive water supply.
    Why it matters:
    Chile remains a copper superpower; desalination is a competitive edge as water scarcity tightens.
    As a pure-play, ANTO is a high-beta expression of electrification copper demand.
    Key near-term watch-items
    Project milestones: first blast and early stripping at Encuentro Sulphides for Centinela’s expansion; construction cadence for desalination/pumping infrastructure at Pelambres.
    Guidance updates relative to schedule/capex.
    Risks: Chilean permitting/water politics; cost inflation; copper price volatility.
  5. Pensana (LSE:PRE): magnet rare earths—mine in Angola, separation in the UK
    Where it fits: Pensana aims to deliver NdPr-rich rare earths for permanent magnets via an integrated model: the Longonjo mine in Angola and the Saltend separation facility in the UK. In October 2025, Pensana’s integrated annual report highlighted US$268m of approved funding for Longonjo Phase 1, with broader financing plans for Longonjo + Saltend (~US$550m) flagged in prior updates; the company says both projects are permitted and advanced on engineering.
    Why it matters:
    NdPr are the torque metals for EV motors and high-efficiency wind turbines; non-China separation capacity is the genuine bottleneck.
    A UK separation plant at Saltend would be strategically important for European/UK magnet supply chains.
    Key near-term watch-items
    Achieving full financial close (debt + equity) and EPC/EPCM contracts moving to execution.
    Offtake with magnet makers and product qualification timelines.
    Risks: Separation chemistry commissioning risk; capital-cost escalation; commodity price swings in NdPr.
  6. Rainbow Rare Earths (LSE:RBW): “above-ground ore” at Phalaborwa (South Africa)
    Where it fits: Rainbow plans to produce magnet rare earths from phosphogypsum stacks—legacy waste from a former fertilizer plant—at Phalaborwa, South Africa, with additional optionality in Brazil (Uberaba). The 2025 corporate updates emphasize lab-driven flowsheet improvements, an updated resource from 2024, and continued test-work progress; management touts the cost advantage of treating pre-cracked material.
    Why it matters:
    If commercialized at scale, “above-ground mining” of waste stacks could slash capex/opex and shorten time-to-market for NdPr/Dy/Tb—highly strategic for OEMs.
    South African industrial heritage + global magnet demand = compelling re-industrialization narrative.
    Key near-term watch-items
    Pilot/DFS outputs, reagent recycle performance and impurity control results.
    Funding pathway (project finance, strategic investors) and offtake pre-sales.
    Risks: Scale-up from lab to plant; permitting and environmental stewardship of gypsum stacks; REE price volatility.
  7. Atlantic Lithium (LSE:ALL): Ewoyaa (Ghana) pushing toward build-decision
    Where it fits: Ewoyaa is a hard-rock lithium project in Ghana. The company has kept the market updated through 2025 on permitting/mining lease status, organizational streamlining, and offtake/dialogue, while acknowledging the shift in lithium prices since 2023. Key July 2025 communications reiterated the mining lease granted in 2023 and the ongoing path to resolve remaining conditions and align with Ghana’s in-country value objectives.
    Why it matters:
    West Africa offers large-scale spodumene potential closer to Atlantic ports; Ghana’s institutions and National Wealth Fund engagement can support local beneficiation.
    A Ghanaian lithium hub would diversify supply beyond Australia/China.
    Key near-term watch-items
    Finalization of mining-lease conditions and any fiscal/royalty adjustments.
    Updated project economics at current prices; offtake terms (floors/caps/indexation).
    Risks: Lithium price cycles; project finance in a soft market; local content requirements impacting NPV if too rigid.
  8. Cornish Metals (LSE:CUSN): bringing UK tin back at South Crofty
    Where it fits: South Crofty is a historic underground tin mine in Cornwall now being dewatered and refurbished toward restart. In 2025, the company accelerated surface and underground works post-financing; UK government (National Wealth Fund) support has been reported, and operators continue to update on pump-station progress, shaft refurbishment and technical studies.
    Why it matters:
    Tin is the glue metal of electronics and the energy transition (solder, power electronics). Europe/UK domestic supply improves resilience.
    South Crofty is permitted (through 2071) with modern water treatment commissioned in 2023—important environmental de-risking.
    Key near-term watch-items
    Completion of mid-shaft pump station (Q4-2025 guidance) and lowering of submersible pumps; sequencing to full dewatering.
    Definitive engineering and funding steps to a construction decision.
    Risks: Underground restart complexity; capital intensity; tin price volatility.
  9. Kenmare Resources (LSE:KMR): titanium minerals & zircon at Moma (Mozambique)
    Where it fits: Kenmare operates the Moma mine—one of the world’s largest producers of ilmenite (titanium feedstock), plus primary zircon and rutile. 2025 updates show the company largely on track against production/cost guidance, with a major Wet Concentrator Plant A upgrade under way, and quarterly reports detailing ilmenite/zircon output and shipments; mid-year commentary hinted at a plan to supplement shipping capacity and to keep guidance intact.
    Why it matters:
    Titanium feedstocks (ilmenite/rutile) are explicitly listed as critical in many jurisdictions for aerospace/defense and pigments; zircon feeds ceramics and advanced materials.
    Kenmare provides scale and operational transparency from a mature operation.
    Key near-term watch-items
    Delivery of the WCP-A upgrade on schedule and budget; dredge installation and downtime management.
    Engagements on mining-rights renewal and H2 shipments.
    Risks: Coastal operational risks (weather, logistics); shipping constraints; pigment market swings.
  10. Yellow Cake (LSE:YCA): listed, low-friction exposure to physical uranium
    Where it fits: Yellow Cake holds physical U₃O₈, offering a pure uranium price vehicle on the LSE. In FY2025 results, the company reported 21.68 million lb of U₃O₈ held (31 March 2025) and provides regular NAV and quarterly updates; subsequent communications in 2025 tracked a rebound in the value of holdings as spot moved.
    Why it matters:
    If you believe in the nuclear renaissance (life-extensions, SMRs, Asia builds), a physical vehicle sidesteps mine-specific risks (geology, capex, outages).
    London listing, transparent RNS and periodic NAV prints make it a clean exposure.
    Key near-term watch-items
    Any new uranium purchases/placings and the cadence of NAV updates.
    Convergence (or divergence) between spot, term prices and YCA’s share price.
    Risks: Uranium spot volatility; liquidity; discount/premium to NAV dynamics.

Cross-cutting themes to watch

1) The copper throttle

Electrification is copper-hungry—grid expansion, motors, data-centre cabling and renewables. That places RIO, AAL, ANTO, GLEN in the secular core.

2) Non-China magnet supply chains

Pensana (Saltend) and Rainbow (Phalaborwa) are part of the West’s attempt to onshore separation and shorten supply chains for NdPr/Dy/Tb. Expect more OEM/trader pre-financing and export-credit involvement where projects cross national-security themes.

3) Lithium normalization vs. scale players

Lithium prices have reset from 2023 peaks. RIO has the balance sheet (Rincon, M&A, Chile JV) to build counter-cyclically and emerge with durable assets; ALL must be crisp on capex discipline and Ghanaian fiscal alignment to clear FID.

4) Domestic revival stories

Cornish Metals and UK policy support suggest a serious attempt to re-root critical minerals domestically (tin now; lithium and rare earth processing also in policy sights). Investors should track the National Wealth Fund pipeline and UK/US/EU critical-minerals frameworks for cheap capital and offtake credits.

5) Nuclear’s macro set-up

Utilities have moved from inventory drawdowns to term contracting. A listed physical play like YCA can be a simpler instrument than picking restart or ISR geology risk in far-flung assets (albeit with NAV premium/discount swings).

6) Circularity & urban mining

Glencore is scaling recycling for batteries and e-waste—this isn’t just ESG optics; it’s access to high-grade, pre-concentrated metal flows that can be economic at scale, reducing primary-mine dependence in certain cycles.

Final word

London offers a full stack of critical-minerals exposure—from copper giants and lithium build-outs to the hardest bottlenecks (magnet rare-earth separation, domestic tin, and physical uranium). The winners will combine orebody quality, flowsheet competence, and financing agility (with policy tailwinds).
