Key Highlights

  • Elevra recorded its highest ore mined and processed volumes at North American Lithium in the September quarter.
  • Delta reported lithium, tantalum and rubidium intercepts at its Mt Ida project.
  • Brazilian Critical Minerals completed a Placement of about A$10 million and appointed a lead design engineer.
  • Each company listed funding, engineering or approval steps expected in the coming months.

Elevra Lithium Limited (ASX:ELV), Delta Lithium Limited (ASX:DLI) and Brazilian Critical Minerals Limited (ASX:BCM) released quarterly activity reports for the period ended 30 September 2026 on 27 October 2026. The updates cover production and sales at a Canadian lithium operation, drilling and scoping work in Western Australia and engineering progress at a Brazilian rare earth project.

Latest Developments

Elevra reported record ore mined of 466,499 wet metric tonnes at North American Lithium, up 25 per cent on the previous quarter. Spodumene concentrate sales were 58,134 dry metric tonnes at an average realised price of US$1,276 per tonne FOB, generating Revenue of US$74 million. Unit operating costs fell 14 per cent to US$780 per tonne sold. The company also noted that musculoskeletal injuries affected its safety rate, and it is reinforcing coaching and critical risk controls.

Delta Lithium reported drilling at Mt Ida that intersected 8 metres at 1.2 per cent lithium oxide, 58 parts per million tantalum oxide and 0.31 per cent rubidium oxide from 423 metres. It has also commenced a scoping study and is testing a tantalum flowsheet on a one-tonne composite. At its Yinnetharra tenure, Delta reported a high-grade rock chip of 6.83 grams per tonne gold, with drilling planned for the fourth quarter pending approvals.

Brazilian Critical Minerals completed a two-tranche placement of about A$10 million at 5.3 cents per share and appointed Altris Engineering as lead design engineer for front-end engineering at the Ema Rare Earth Project. The company said a public hearing in Apuí formed part of the land-access process, with the final INCRA consent still required. It also agreed to acquire a 90 per cent interest in Sais Nordeste, a magnesium sulphate producer, and reported about A$12.2 million in cash at quarter end.

Sector Context

Lithium markets remain sensitive to pricing, and producers report results against realised prices and operating costs. Development-stage companies such as Delta and Brazilian Critical Minerals depend more on drilling outcomes, study timelines and environmental or land approvals. The range of stages across these three companies highlights the different financial and operational demands of producing and exploring critical minerals businesses.

Across the three companies, the common thread is execution. For a producer, the focus is on stable throughput, recovery rates and unit costs, while for explorers and developers it is on converting drilling and testwork into study outcomes and approvals. Lithium and critical mineral prices move in cycles, and companies that are still in study or permitting phases may be less exposed to short-term price changes but more exposed to funding conditions and project timelines.

Risks to Consider

Commodity prices, operating costs and safety performance can change quickly for producers. Exploration and scoping results may differ from future studies, and Delta's flowsheet work remains at an early stage. Brazilian Critical Minerals still requires land-access consent and environmental licensing, and its cash balance will need to support engineering, permitting and offtake work. Shareholders may also face dilution from future Capital raisings.

What to Watch Next

Readers may look for Elevra's progress on the North American Lithium expansion, Delta's Mt Ida scoping study and Yinnetharra drilling, and Brazilian Critical Minerals' INCRA consent and completion of the Sais Nordeste acquisition.

Final Word

The three quarterly reports show different stages of lithium and critical minerals activity, from production and cost management to scoping and permitting. Future releases from each company will indicate whether these milestones progress as outlined, and investors can review the filings as they are published.
