Independent Analysis Supports Hydraulic Borehole Mining Method Applicability for Bonnie Claire Lithium Project

Vancouver, British Columbia – April 29,2026 – Nevada Lithium Resources Inc. (TSXV: NVLH; OTCQB: NVLHF; FSE: 87K) (“Nevada Lithium” or the “Company”) is pleased to announce the results of an independent technical due diligence review conducted by WSP UK Limited (“WSP”) on the Hydraulic Borehole Mining Method (“HBHM”) 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: “We are pleased to announce the results of a technical assessment by WSP UK Limited, a subsidiary of WSP Global Inc., one of the world’s foremost engineering and design firms. With significant in-house hydraulic borehole mining experience to validate its recommendations, WSP has assessed the viable application of the Hydraulic Borehole Mining Method (HBHM) to access Bonnie Claire’s high-grade mineralization at depth. Currently, this mineralization includes recoverable lithium, boron, cesium and rubidium, with the potential recovery of additional critical minerals such as rare earth elements.   Importantly, this independent technical assessment does not recommend an in-field test of HBHM for the Company’s upcoming Preliminary Feasibility Study (PFS). WSP has advised Nevada Lithium that additional bench-scale testing and modeling would be sufficient for the mining section of the PFS. […]
