Nevada Lithium Announces Winter Work Program Focused on Further Enhancing Value of the Bonnie Claire Lithium & Boron Project

Nevada Lithium Resources Inc. (NVLH) announced on December 11, 2025, the commencement of a winter work program for its 100% owned Bonnie Claire lithium and boron project. The program comprises three main technical workstreams: 1. A proof-of-concept study with Kemetco Research Inc. to evaluate the recovery of cesium and rubidium from the project's flowsheet. This directly follows up on the September 17, 2025 news identifying these critical minerals. 2. A technical due diligence review by a global engineering firm concerning the proposed Hydraulic Borehole Mining (HBHM) method. 3. A research agreement with the University of Naples Federico II to investigate lithium residency within the clay minerals, aiming for improved extraction.

The company's CEO, Stephen Rentschler, expressed optimism, anticipating these projects will provide useful technical information with potentially positive economic implications, especially the potential for additional critical mineral recovery (cesium and rubidium) to create revenue streams beyond lithium and boron. The Vice President of Exploration, Dr. Jeff Wilson, is also scheduled to present at the 2026 PDAC Convention. The news reiterates that the Preliminary Economic Assessment (PEA) is preliminary and includes Inferred Mineral Resources considered speculative.

This latest news represents a positive, albeit routine, step in the ongoing development and optimization of the Bonnie Claire project. It directly follows the material positive news from November 11, 2025, where boron was added to the US Critical Minerals List, enhancing the project's strategic importance and economic potential. The current work program aims to build upon this by actively exploring additional revenue streams (cesium and rubidium) which were identified as significant in the September 17, 2025 news.

The focus on a proof-of-concept study for cesium and rubidium recovery is a logical progression and aligns with the CEO's commentary in previous releases about identifying additional critical minerals. If successful, these could indeed boost the already robust PEA economics. The technical due diligence on the Hydraulic Borehole Mining (HBHM) method is also crucial, as HBHM is a foundational aspect of the Lower Zone mining plan in the PEA, and de-risking this method is important for the project's overall viability. Investigating lithium residency is a long-term optimization effort.

While the initiatives are positive and demonstrate progress, they are studies and reviews, not definitive results or confirmed economic enhancements at this stage. Therefore, while contributing to the overall de-risking and value enhancement trajectory of the project, this specific announcement is not considered a "game changer." It is in line with expectations for a project of this scale following a PEA and the identification of co-products. The market's reaction has been muted, with the stock closing unchanged on the day of the news.

Nevada Lithium Resources Inc. is an exploration and development company primarily focused on its 100% owned Bonnie Claire Lithium & Boron Project located in Nye County, Nevada, USA. The project is strategically positioned in a known lithium jurisdiction.

The Bonnie Claire Project is characterized as one of the world's largest sediment-hosted lithium and boron deposits. Key aspects of its development include: * Mineral Resource Estimate (MRE): An updated NI 43-101 MRE (effective September 24, 2024, filed December 16, 2024) significantly increased the size and grade of the Lower Zone Inferred Lithium Mineral Resources (68% increase in LCE tonnage, average grade tripled to over 3,000 ppm). It also reported maiden Indicated Lithium and Boron Resources. The project has two zones: * Lower Zone: High-grade lithium and boron, planned for underground Hydraulic Borehole Mining (HBHM). * Upper Zone: Moderate lithium and low boron grades, with potential for conventional open-pit mining (not examined in the initial PEA). * Preliminary Economic Assessment (PEA): Announced on August 6, 2025, and filed on September 9, 2025, the PEA reported robust economics for the project, including: * After-tax NPV(8%) of US$6.83 billion. * After-tax Internal Rate of Return (IRR) of 32.3%. * Capital payback period of 2.8 years. * Mine life of 61 years. * Estimated annual production of 62,300 tonnes of lithium carbonate and 129,500 tonnes of boric acid. * Operating costs of US$6,800 per tonne LCE (net of boric acid credits). * Metallurgical Work: Initial test work (February 26, 2025) demonstrated >95% lithium extraction via acid leach and potential for boric acid co-production as an additional revenue stream. * Critical Mineral Status: Boron was added to the 2025 US Critical Minerals List (November 11, 2025), enhancing the project's strategic importance and potential for government support. * Additional Critical Minerals: Significant amounts of rubidium and cesium have been identified in existing drill core and Pregnant Leach Solution (PLS) (September 17, 2025), with the company actively exploring economic recovery options. * Strategic Partnerships: The company signed a Letter of Intent (LOI) with Hydro Lithium Inc. (September 24, 2025) to evaluate Hydro Lithium's proprietary extraction technologies (CULH, CULX) for critical minerals from Bonnie Claire, and potentially other North American properties.

The company uplisted to the TSX Venture Exchange on December 31, 2024, from the CSE, aiming to enhance its investor profile and access to capital markets.
