Jindalee Lithium Secures US Federal Approval for McDermitt Expansion

US Government Clears Path for Major Drilling Campaign at America's Largest Lithium Project

Jindalee Lithium Limited (ASX: JLL, OTCQX: JNDAF) has secured a critical regulatory milestone that positions the company for a significant expansion of drilling activities at its 100% owned McDermitt Lithium Project in Nevada. The US Bureau of Land Management (BLM) has approved the company's Exploration Plan of Operations (EPO), following an extensive two-and-a-half-year environmental review process that included comprehensive public consultation and multi-agency coordination.

This approval represents more than just regulatory clearance—it's the green light for major infill drilling operations planned for the second half of 2026, designed to feed directly into McDermitt's upcoming Feasibility Study. With McDermitt recognised as one of the largest lithium deposits globally, this development marks a pivotal moment for both the company and America's domestic lithium supply chain.

The EPO approval follows Jindalee's recently completed Pre-Feasibility Study, which confirmed McDermitt's potential as a long-life, low-cost lithium operation. Managing Director Ian Rodger emphasised the strategic importance:

"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."

What This Regulatory Win Means for Operations

The approved EPO fundamentally transforms Jindalee's operational capacity at McDermitt, enabling a significant increase in on-site activity that was previously restricted under existing permits. Furthermore, the scope of approved activities includes comprehensive drilling and study programmes.

Expanded Drilling Operations:

• Major infill drilling programme targeting 2H 2026 implementation
• Enhanced geological data collection across the deposit
• Fresh sample acquisition for advanced geotechnical studies
• Continued metallurgical test work to optimise processing parameters

Integrated Study Programme:

• All drilling results will feed directly into the Feasibility Study
• Environmental data collection to support future development phases
• Comprehensive resource definition to support project financing

The timing aligns strategically with Jindalee's development pathway. With state-level permit applications already lodged and progressing through normal regulatory channels, the company expects these additional approvals during 1H 2026—perfectly positioning for the major drilling campaign to commence shortly thereafter.

Understanding Environmental Plan of Operations (EPO)

For investors new to US mining regulations, an Exploration Plan of Operations represents a comprehensive regulatory framework that governs how mining companies can conduct exploration activities on federal lands. Moreover, the EPO process is particularly rigorous, requiring extensive environmental impact assessments under the National Environmental Policy Act (NEPA).

Why EPO Approval Matters:

• Regulatory certainty for expanded operations
• Environmental compliance established upfront
• Community and stakeholder buy-in through public consultation process
• Scalability for future development phases

The two-and-a-half-year review timeline for McDermitt's EPO reflects both the thoroughness of the process and the project's scale. In addition, the BLM's Finding of No Significant Impact indicates that proposed activities can proceed without triggering more extensive environmental impact studies—a positive outcome that streamlines the path forward.

Key Terms:

• NEPA (National Environmental Policy Act): Federal law requiring environmental assessment of major projects
• Environmental Assessment (EA): Detailed study of potential environmental impacts
• Decision Record: Final BLM determination approving the proposed activities
• Finding of No Significant Impact: Determination that activities won't cause major environmental harm

The EPO process was originally lodged in August 2022, deemed complete in May 2023, before commencing the environmental review process. Subsequently, the Draft Environmental Assessment was published for public review in March 2025, with the public comment period closing in April 2025.

Strategic Drilling Programme Sets Stage for Development

The approved drilling programme represents far more than routine exploration—it's a targeted campaign designed to de-risk and optimise McDermitt's development pathway. The infill drilling approach focuses on enhancing resource definition and supporting engineering decisions.

Resource Definition Enhancement:

• Increased drill density across priority zones
• Geological continuity confirmation for mining planning
• Resource category upgrades from Inferred to Indicated classification

Engineering and Metallurgy Support:

• Fresh samples for geotechnical analysis supporting mine design
• Metallurgical test work expansion to optimise processing parameters
• Environmental baseline data collection for permitting future phases

Feasibility Study Integration:

• All data feeds directly into comprehensive Feasibility Study
• Results will inform final project economics and financing decisions
• Timeline positions completion for optimal market conditions

The strategic timing cannot be understated. With lithium markets showing signs of recovery and US government focus intensifying on domestic critical mineral supply, McDermitt's development pathway aligns with both market cycles and policy priorities.

The 2H 2026 drilling timeline positions the project to capitalise on improving lithium market conditions while maintaining regulatory momentum. This operational cadence demonstrates sophisticated project management in a complex regulatory environment.

McDermitt's Position in America's Lithium Landscape

McDermitt's significance extends well beyond company-specific metrics—it represents a cornerstone asset in America's domestic lithium supply strategy. However, recent geopolitical developments have amplified focus on domestic critical mineral production, with lithium at the forefront of strategic priorities.

Scale and Strategic Importance:

• One of the largest lithium deposits globally
• 100% ownership with unencumbered offtake rights
• Nevada location providing mining-friendly jurisdiction
• Magnesium co-product potential adding additional value streams

Government Engagement:

• Strong engagement from US Department of Energy
• Federal policy alignment with domestic supply objectives
• State and local support through collaborative regulatory process

The Pre-Feasibility Study completed in November 2024 confirmed McDermitt's scale, long-life, and low-cost production potential—characteristics that position the project as a strategic national asset rather than simply a commercial venture.

Understanding Lithium's Critical Role in Energy Transition

Lithium has emerged as one of the most strategically important minerals in the global energy transition. This soft, silvery-white metal forms the core component of rechargeable lithium-ion batteries that power electric vehicles, energy storage systems, and consumer electronics.

Why Lithium Matters:

• Battery Technology: Essential component enabling high-energy density storage
• Electric Vehicle Growth: Every electric vehicle requires approximately 10-15 kg of lithium
• Grid Storage: Large-scale energy storage systems require substantial lithium quantities
• Supply Chain Security: Most global lithium production currently concentrated in few countries

US Strategic Imperative:
The United States currently imports most of its lithium requirements, creating supply chain vulnerabilities for critical technologies. Domestic projects like McDermitt represent opportunities to reduce import dependence while supporting the domestic electric vehicle and renewable energy sectors.

This development addresses the strategic gap, potentially providing significant domestic lithium supply to support America's energy security objectives.
