Jindalee Lithium Limited (Jindalee, or the Company; ASX: JLL, OTCQX: JNDAF) is pleased to advise that its 100%-owned US subsidiary, HiTech Minerals Inc. (HiTech), has signed a Memorandum of Understanding (MoU) with RESOLVE, Inc. (RESOLVE), an independent, nonpartisan, nonprofit organization1. RESOLVE has extensive experience convening stakeholders and rightsholders on complex environmental, natural-resource and social challenges, including responsible mineral supply chains, critical minerals, biodiversity outcomes and land conservation. The MoU establishes a framework for HiTech and RESOLVE to explore the creation of a voluntary Stewardship Area in the broader Oregon-Nevada caldera region, where HiTech is advancing the McDermitt Lithium Project. The Stewardship Area is intended to support improved environmental outcomes for high-value habitat areas, alongside HiTech’s advancement of responsible domestic lithium development in the McDermitt Caldera. Under the MoU, HiTech and RESOLVE expect to engage with stakeholders and rightsholders in the region to identify potential land areas that may warrant investment, protection, restoration or other stewardship measures. HiTech will consider funding part of these stewardship measures agreed through the process subject to meeting McDermitt Lithium Project development milestones. Any voluntary stewardship measures identified through this process would be in addition to, and not a substitute for, HiTech’s obligations under applicable environmental laws, permitting processes, other benefit agreements and regulatory requirements. The MoU does not create any binding commitment to a specific funding amount, land area, stewardship outcome or regulatory result.

HiTech Minerals MoU with RESOLVE Jindalee Managing Director and CEO Ian Rodger commented: “HiTech recognizes the ecological, cultural and community values of the broader Oregon-Nevada McDermitt Caldera region, and the importance of advancing McDermitt in a way that is responsible, transparent and constructive. “This MoU with RESOLVE provides a practical framework to explore how domestic lithium development and long-term environmental stewardship objectives can be progressed together. Importantly, the process is at an early stage, and any future Stewardship Area will need to be shaped through engagement with Tribal Nations and stakeholders, technical assessment and the ongoing permitting pathway.” RESOLVE CEO Stephen D’Esposito commented: “This MoU marks an important, initial step toward pairing responsible domestic lithium development with potential large-scale conservation. We are excited to explore the opportunity to advance goals on critical minerals, energy policy, and nature by proactively identifying landscapes for protection and restoration, as a twin aim. We appreciate HiTech’s leadership, responsible approach and interest.” Authorised for release by the Jindalee Board of Directors.

The Company recently completed a Pre-Feasibility Study (PFS) confirming McDermitt’s scale, long-life, and low-cost production potential, with strong engagement from U.S. government agencies, including the Department of Energy. As a deeply undervalued lithium (and potentially magnesium) developer, Jindalee presents a compelling investment opportunity ahead of the next lithium market upcycle.
