Everest Metals has submitted a full international patent application for its direct rubidium extraction process, enhancing efficiency, selectivity, and scalability. This follows a provisional application filed in February 2025, incorporating updated technical details from 2025 and early 2026.

The process has achieved up to 97% rubidium recovery from ore at the Mt Edon project in Western Australia. The filing under the Patent Cooperation Treaty allows the company to defer national applications for 18 months, providing time for technology development and commercial assessment. The project has a 3.6Mt inferred resource with notable grades of rubidium and lithium oxide, and mineralisation remains open for expansion.
