Highlights

  • Lynas Rare Earths (ASX:LYC) reported a significant improvement in FY2026 Earnings as higher NdPr pricing and increased sales supported Revenue and profit growth.
  • Iluka Resources (ASX:ILU) continues to advance the Eneabba rare earths refinery while managing softer conditions across its established mineral-sands operations.
  • Nickel Industries (ASX:NIC) is expanding its exposure to battery-grade nickel materials through the Excelsior Nickel Cobalt HPAL project in Indonesia.
  • Policy support, processing capacity, funding, Commodity pricing and project execution remain central themes across the three ASX 300 critical-minerals companies.

Critical minerals have become one of the defining market stories of 2026, and September has kept the sector firmly in the spotlight. Government policy — not just commodity prices — is now a primary sector driver, after Canberra moved to underpin selected critical minerals with a price-floor mechanism and strategic reserves, and as the US–Australia framework on critical-minerals Supply chains continued to take shape.

Against that backdrop, Lynas Rare Earths (ASX:LYC) reported a sharply higher full-year profit on 26 August 2026, Iluka Resources (ASX:ILU) pressed ahead with its part-built Eneabba rare earths refinery after a softer half-year result on 19 August, and Nickel Industries (ASX:NIC) lifted first-half profit as its Indonesian high-pressure acid leach (HPAL) expansion reached first production.

Three very different businesses are being discussed in the same breath because they all sit inside the effort to build materials supply chains outside China. For investors following the ASX 300, the questions in September 2026 are about execution, funding and how durable the policy tailwind proves to be.

Why the Critical Minerals Sector Is in Focus in September 2026

Critical minerals — rare earths, mineral sands, nickel, and related materials — feed magnets, batteries, defence systems and electrification. What changed in 2026 is the policy layer. Australia has moved to establish a price floor for certain critical minerals and to build strategic stockpiles, while the US and Australia have advanced a framework aimed at diversifying supply away from Chinese processing dominance. Several ASX rare-earth names have consequently attracted increased investor attention through the year.

  • Policy support: Price-floor and strategic-reserve measures aim to de-risk projects that struggle to compete with Chinese pricing.
  • Supply-chain security: Western governments and manufacturers want magnet, battery and defence inputs sourced outside China.
  • Prices remain volatile: Rare-earth prices firmed sharply into mid-2026, but critical-minerals pricing overall has a long history of cyclicality.

The connective tissue is strategic rather than purely commodity-driven. That makes announcements about offtake agreements, government funding and processing milestones as important as spot prices. It also introduces a distinct risk: policy can shift, and pricing support that is announced is not always the pricing support that is delivered.

Why Lynas Rare Earths Limited (ASX:LYC) Is in Focus

Lynas Rare Earths Limited (ASX:LYC) is the largest rare-earths producer outside China and is directly exposed to the evolving policy and pricing environment for critical minerals. On 26 August 2026, it reported an FY2026 net profit after tax of A$222.4 million, up sharply from A$8.0 million in FY2025, on revenue of A$977.9 million — more than double the prior year.

Total rare-earth oxide sales rose to 12,122 tonnes and neodymium-praseodymium (NdPr) sales to 7,337 tonnes, at a record average selling price of A$80.7/kg. The company attributed much of the improvement to a recovery in NdPr prices through the year.

Lynas Rare Earths (ASX:LYC) also produces separated heavy rare earths — dysprosium and terbium — at its Malaysian plant, a capability it first established in 2025 and which remains rare outside China. During FY2026, it renewed its Malaysian operating licence for ten years and commissioned new samarium oxide capacity.

Management has pointed to government-backed floor-price arrangements as support for its economics. Its US processing project in Texas remains a longer-dated growth avenue that has been linked to potential government funding.

Investors are watching NdPr and heavy-rare-earth pricing, Mt Weld and Malaysia throughput, and progress on US expansion.

Why Iluka Resources Limited (ASX:ILU) Is in Focus

Iluka Resources Limited (ASX:ILU) is a very different proposition: an established mineral-sands producer covering zircon, rutile and synthetic rutile that is transforming itself into a rare-earths refiner.

On 19 August 2026, it reported first-half 2026 results for the period to 30 June showing mineral-sands revenue of A$433 million, down 22% year-on-year, and a net loss after tax of A$24 million, against a A$92 million profit a year earlier. Zircon, rutile and synthetic-rutile production fell to 106kt from 280kt as the company managed output into softer demand. It nonetheless lifted the Interim Dividend to a fully franked 3 cents per share.

The strategic centrepiece is the Eneabba rare earths refinery in Western Australia, reported as around 60% complete and on schedule, with the Capital estimate reaffirmed at A$1.7–1.8 billion.

Iluka Resources (ASX:ILU) disclosed a feedstock supply agreement with VHM and an initial magnet-oxide offtake with a global automotive company. Eneabba is central to the "processing outside China" thesis and has been publicly linked to Australian Government support.

The near-term story is execution and funding on Eneabba against a weaker mineral-sands earnings backdrop.

Why Nickel Industries Limited (ASX:NIC) Is in Focus

Nickel Industries Limited (ASX:NIC) is an Indonesia-focused nickel producer with rotary-kiln electric-furnace (RKEF) operations and a growing HPAL footprint aimed at battery-grade material.

In its first-half 2026 reporting, with the half-year results webcast held on 26 August 2026, the company reported net profit after tax up 191% to US$74.3 million on 13% higher revenue, with its Hengjaya mine delivering record quarterly earnings and the cash position strengthening to about US$270 million against net Debt near US$982 million.

The pivotal development is the Excelsior Nickel Cobalt (ENC) HPAL project, which produced first mixed hydroxide precipitate (MHP) in July 2026 and was targeting first cathode shortly after, with nameplate capacity flagged for the fourth quarter of 2026.

HPAL takes Nickel Industries (ASX:NIC) further up the value chain toward battery-precursor materials. The company also reported a resource upgrade at Sampala and continued expansion of its HPAL interests.

Nickel pricing, Indonesian policy and HPAL ramp-up remain important swing factors for the business.

What Connects These Three Stocks?

All three sit inside the critical-minerals supply-chain theme, but they occupy different points on the spectrum.

Lynas Rare Earths (ASX:LYC) is the established, cash-generative rare-earths producer with heavy-rare-earths capability and direct Leverage to the 2026 price recovery and policy support.

Iluka Resources (ASX:ILU) is a transition story — a mature mineral-sands Business funding a large, part-built refinery that would make it a Western magnet-oxide supplier if executed on budget.

Nickel Industries (ASX:NIC) is a battery-materials play, using Indonesian scale and HPAL to move toward precursor chemicals for lithium-ion batteries.

The shared driver is strategic: Western governments and manufacturers want magnet metals, mineral-sands Derivatives and battery inputs sourced and processed outside China, and policy is increasingly supporting that goal.

The key differences are stage and commodity. Lynas is producing and profitable; Iluka is mid-build and reported a first-half loss; Nickel Industries is ramping a new processing route. Their commodity exposures — rare earths, mineral sands and nickel — behave differently and respond to different Demand cycles, so a favourable environment for one is not guaranteed to translate directly to the others.

What Could Move These Stocks Next?

  • Rare-earth prices: NdPr and heavy-rare-earth pricing directly influence Lynas earnings and sentiment across the sector.
  • Policy detail: Concrete terms on Australia's price-floor and strategic-reserve measures, and further US–Australia framework specifics, could shape the sector outlook.
  • Eneabba milestones: Construction progress, funding confirmation and first-production timing for Iluka's refinery.
  • HPAL ramp-up: Nickel Industries reaching first cathode and nameplate capacity at ENC, alongside nickel-price and Indonesian-policy developments.
  • Quarterly updates and the 29 September RBA decision: Broader rate and currency settings can influence sentiment toward capital-intensive miners, while a softer Australian dollar can support Australian producers with US-dollar receipts.

What Are the Risks?

Commodity-price Volatility is the common thread: rare earths, mineral sands and nickel have all seen sharp cycles, and policy support may not fully insulate producers.

Execution and funding risk is particularly relevant for Iluka, given the scale of the Eneabba build and its weaker interim earnings backdrop, and for Nickel Industries as it ramps HPAL.

Policy risk cuts both ways — announced pricing support can be revised, and geopolitics can shift quickly. Concentration is also a factor: Nickel Industries is heavily exposed to Indonesian operations and policy, while Lynas relies on Malaysian processing.

Currency movements, cost Inflation and capital intensity add further variables. None of these companies is immune to a broad risk-off move across resources equities.

What ASX Investors Should Watch Next

The critical-minerals theme has meaningful policy momentum behind it, but September 2026 is also a period in which investors may distinguish strategic narrative from delivered results.

For Lynas Rare Earths (ASX:LYC), the indicators to monitor are rare-earth pricing, production throughput and progress on US expansion.

For Iluka Resources (ASX:ILU), the questions are whether Eneabba stays on budget and schedule, how its funding is finalised, and when its mineral-sands earnings recover.

For Nickel Industries (ASX:NIC), the key areas are HPAL ramp-up, the trajectory of nickel prices and Indonesian policy.

Across all three, investors may also monitor firm policy detail on Australia's price floor and strategic reserves, further US–Australia framework announcements, and upcoming quarterly and production updates. Each company's longer-term path will depend on execution as much as on the supportive policy backdrop.
