What Everest Metals does

Everest Metals Corporation Limited is developing the Mt Edon Critical Mineral Project in Western Australia, including rubidium extraction and purification technology.

Mt Edon rubidium testwork

In an ASX announcement dated 20 October 2026, Everest Metals reported completion of direct rubidium extraction (DRE) metallurgical testwork by Edith Cowan University, supported by funding from the MRIWA METS Innovation Program and AEA Ignite. Results include up to 90% rubidium recovery from representative Mt Edon materials through batch roasting and water leaching, a 60% reduction in water use in the leaching stage (10:1 to 4:1) enabling leaching at room temperature, and a reduced potassium-to-rubidium ratio of about 1.52:1 in a single purification pass, consistent over 20-plus cycles.

Bipolar membrane electrodialysis, incorporating the company’s patent-pending technology, removed processing chemicals while retaining rubidium so the solution could be recycled. Manufacture of an in-house DRE purification reagent has been validated, with equipment being commissioned to Supply future pilot plant construction.

Sector context

Exploration-stage resource companies do not generate production revenue, and their share prices can move sharply on drilling results, funding news and Commodity sentiment.

Risks and uncertainties

The results are laboratory testwork and may not translate to a pilot or commercial plant, and the company has not published a resource-based economic study in this announcement. Funding for a pilot plant is not described. Closing prices on a single day are not the same as the 52-week high or low price, and a 52-week extreme does not indicate where a share price will move next.

Catalysts to watch

Items to watch include commissioning of the reagent Manufacturing equipment, pilot plant development and funding.

Closing perspective

Everest Metals’ 20 October 2026 release reported laboratory rubidium recovery of up to 90%. A pilot plant would test the process at larger scale.
