Latest Lithium And Rubidium News

IRIS Metals posted a $22.3 million loss for FY26, driven by major impairments on exploration assets and elevated share-based payments. The company pivots away from Edison and Tin Mountain projects, focusing on lithium-rubidium in South Dakota and tungsten in Montana.

Morella Corporation’s final 2026 drilling results at Mt Edon reinforce broad rubidium mineralisation and reveal multiple higher-grade zones, advancing the project toward its maiden JORC Mineral Resource Estimate.

Askari Metals (ASX:AS2) has validated continuous polymetallic mineralisation including tin, lithium, tantalum, rubidium, and caesium at its PS Pegmatite Target within the Uis Project in Namibia, setting the stage for planned drilling in H2 2026.

IRIS Metals has revealed a 3.03Mt lithium resource at its fully permitted Beecher Project in South Dakota, featuring a notable rubidium component with a high-grade zone containing around 2,100 tonnes of Rb2O. This positions Beecher as a rare multi-commodity critical minerals asset in a top US mining jurisdiction.

Askari Metals has completed data compilation at its Nejo Gold and Copper Project, setting the stage for a 5,000m maiden drilling campaign targeting high-grade gold and copper. Meanwhile, trenching at its Uis Project in Namibia reveals robust polymetallic mineralisation, including tin, tantalum, lithium, rubidium, and caesium, underpinning plans for RC drilling later this year.

Delta Lithium’s March quarter report highlights robust high-grade lithium drilling at Mt Ida, successful production of battery-grade lithium and rubidium carbonates, and ongoing exploration progress at Yinnetharra, supported by a strong $52 million cash position.

Askari Metals reports strong Phase 1 trenching results at its 100%-owned Uis Project, confirming continuous high-grade polymetallic mineralisation including tin, lithium, tantalum, rubidium, and caesium. These findings bolster confidence ahead of planned drilling in H2 2026.

Delta Lithium has successfully produced battery-grade lithium carbonate and high-grade rubidium carbonate from mica concentrate at its Mt Ida project, confirming strong recovery rates and potential new revenue streams.

Morella Corporation has completed a 20-hole drilling program at its Mt Edon Rubidium-Lithium Project, intercepting thick, continuous pegmatite zones that bolster the case for a significant mineral resource. Assay results are awaited as the company moves toward a maiden Mineral Resource Estimate.

IRIS Metals has secured a farm-in agreement to earn up to 100% ownership of the Finley Basin Tungsten Project in Montana, marking a strategic expansion into a critical mineral vital for defence and advanced manufacturing.

Askari Metals reports strong Phase 1 trenching results at its 100%-owned Uis Project in Namibia, confirming significant polymetallic mineralisation including tin, lithium oxide, tantalum, rubidium, and caesium. The company plans reverse circulation drilling in Q2 2026 to further define the resource.

IRIS Metals has raised $5.5 million through a strongly supported placement to accelerate development of its critical minerals portfolio in the United States, including early sales from its Beecher Project.
