Jindalee Lithium Limited (Jindalee, or the Company; ASX: JLL, OTCQX: JNDAF) is pleased to advise that the US Bureau of Land Management (BLM) has issued a Finding of No Significant Impact and Decision Record1 approving the Exploration Plan of Operations (EPO) for Jindalee’s 100% owned McDermitt Lithium Project (McDermitt, Project), one of the largest lithium deposits in the United States (US) and of global significance2. The EPO for McDermitt was originally submitted to the BLM in August 2022 and deemed complete in May 20233 before commencing the environmental review process required under the National Environmental Policy Act (NEPA). The Draft Environmental Assessment (EA) was published for public review on 24 March 2025, with the public comment period closing 25 April 20254. The BLM then prepared responses to comments and finalised the EA in consultation with relevant agencies, with the Decision Record issued 8 December 20251. BLM’s approval of the EPO will allow Jindalee to significantly increase on-site activity, including infill drilling to provide additional geological and environmental data, together with fresh samples for geotechnical studies and further metallurgical test work, with results from this work to feed into the McDermitt Feasibility Study. Applications for the requisite state-level permits have already been lodged and are progressing through the normal process, with outcomes expected in 1H 2026. Jindalee’s Managing Director and CEO Ian Rodger commented: “BLM’s approval of our EPO is a major milestone for the Project and the culmination of extensive environmental studies, community reviews and consultation with State, Federal and Tribal governments. We made changes to the EPO to address concerns raised during the process and we thank all parties for their contributions. McDermitt is a strategically important source of lithium (and potentially magnesium) for the US, and with the EPO now approved we look forward to advancing the Project for the benefit of all stakeholders.” Authorised for release by the Jindalee Board of Directors.
