Additional Critical Mineral Potential Confirmed with 95.9% Cesium and 86.9% Rubidium Extraction at Bonnie Claire Lithium Project

Vancouver, British Columbia – March 25,2026 – Nevada Lithium Resources Inc. (TSXV: NVLH; OTCQB: NVLHF; FSE: 87K) (“Nevada Lithium” or the “Company”) is pleased to provide a technical update on its 2026 metallurgical program at its 100% owned Bonnie Claire Lithium project (the “Project” or “Bonnie Claire”), located in Nye County, Nevada. Nevada Lithium’s CEO, Stephen Rentschler, comments: “I am pleased to announce that the opportunity to produce additional critical minerals at Bonnie Claire continues to grow. Recently completed lab work has confirmed very high cesium and rubidium extraction rates from pregnant leach solution (PLS). This PLS was generated by the recovery flow sheet developed for the Bonnie Claire Preliminary Economic Assessment, as announced by Company news release, dated August 6, 2025. Following the successful leaching of cesium and rubidium, an initial test of two ion exchange resins resulted in a successful proof of concept recovery method. The Company is confident that the ion exchange recovery method can be improved upon with trials of additional resin chemistry and further flow sheet development. A follow-on work program to optimize cesium and rubidium recovery is currently being evaluated by Nevada Lithium’s technical team. Cesium and rubidium grades are strongly correlated to high […]
