Announcement PDF ASX Announcement 2 June 2026 ASX: OD6 1 OD6 APPOINTS WESTLAND AS PERMITTING CONSULTANTANT TO ACCELERATE QUINN FLUORSPAR PROJECT, NEVADA OD6 Metals Limited (ASX: OD6) (“OD6” or “the Company”) is pleased to announce the appointment of WestLand Engineering & Environmental Services (“WestLand”) as permitting consultant for its Quinns Fluorspar Project (“Project”) in Nevada, USA. HIGHLIGHTS • Tier-1 U.S. permitting consultant appointed with extensive USFS, NEPA and Fast 41 experience • WestLand has been engaged to manage permitting and environmental baseline programs under the United States Forest Service (“USFS”) framework, supporting a streamlined pathway from exploration through to potential development • A front-end loading permitting approach is being undertaken with all current claims being fully surveyed which can be utilised across a 10 year validity period inclusive of drill and mine permitting. • The requisite Pre-Plan Letter introducing the Project and proposed exploration activities has been submitted during May 2026 • Seasonal biological and archaeological baseline surveys will be completed in the coming months • Targeting Categorical Exclusion (CE) to enable the maiden drilling program to occur • A Plan of Operations (POO) and other required supporting documentation will be submitted to the USFS • Bulk sampling program is planned to supportmetallurgical testwork across multiple target areas within the Project Area • This approach positions OD6 to avoid duplication of studies and significantly streamline future permitting requirements • Alignment with U.S. critical minerals policy and FAST-41 permitting framework potential Managing Director Brett Hazelden, commented: "The appointment of WestLand marks a critical step in accelerating the Quinns Fluorspar Project through the U.S. permitting process. By front-end loading environmental baseline studies,we are positioning the Project fora streamlined approval pathway, while aligning with U.S. critical minerals policy and potential FAST-41 pathways. Importantly, this work also underpins our ability to pursue bulk sampling and metallurgical testwork, advancing the Project toward development." 2 Permitting Strategy – Front End Loading Approach OD6 has adopted a proactive permitting strategy designed to streamline project requirements and reduce future approval risk. Westland is a Tier-1 U.S. permitting consultant with extensive USFS, NEPA and Fast 41 experience. WestLand will undertake: • Class III cultural (archaeological) survey • Comprehensive biological baseline surveys (flora & fauna) • Supporting environmental and regulatory documentation under National Environmental Policy ACT (NEPA) Importantly, these baseline surveys are expected to have validity of up to 10 years, enabling their use and support for the following permitting actions: • Initial POO application • Expanded POO submission • Potential mining and development POO submission This approach positions OD6 to avoid duplication of studies and significantly compress future permitting timelines. Initial Drilling – POO with Approval Under Categoric Exclusion (CE) The Company is targeting an initial drill program under a POO with approval via CE with the USFS. The CE approval pathway is designed for low-impact exploration activities, typically including: • Less than 1 mile (~1.6km) of new access roads • Less than 5 acres (~2 hectares) of surface disturbance • One year to complete exploration and corresponding reclamation activities OD6 has submitted initial concepts including drill pads, access routes and associated infrastructure consistent with CE thresholds. OD6 will coordinate closely with the USFS to complete applications and baseline studies required for federal approvals. Plan of Operations (POO) – Expanded Drilling Pathway analysed and approved under an Environmental Assessment (EA) with Corresponding Reclamation Permit In parallel with the CE application, OD6 intends to scale exploration under an expanded POO. The POO will: • Enable expanded drilling programs beyond one mile of constructed road and 5 acres of surface disturbance • Support resource definition and step-out exploration • Incorporate biological and cultural baseline data collected in 2026 • Be formatted to include sections in compliance with Nevada State Regulations, required for Projects exceeding 5 acres of surface disturbance The Company will leveraging early baseline work to streamline assessment and approvals. 3 Bulk Sampling and Metallurgical Testwork As part of the drilling approvals, OD6 intends to: • Apply for bulk sampling permits across multiple areas • Extract representative material for metallurgical testwork and flowsheet optimisation This strategy aligns with recent U.S. project precedents where bulk sampling has: • Accelerated development pathways • Supported offtake and processing discussions • Reduced technical and commercial risk Strong Alignment with US Policy and Fast-41 Potential The Project is strongly aligned with U.S. Government priorities to secure domestic critical mineral supply chains, including fluorspar. Recent developments in U.S. policy include: • Ongoing efforts by the USFS to streamline permitting processes, including clearer thresholds and faster environmental reviews • Increased federal focus on critical minerals supply security • Expansion of frameworks such as FAST-41, designed to accelerate permitting of strategic infrastructure projects (refer FAST-41 Program | Permitting Council) FAST-41 designation provides: • Coordinated federal agency approvals • Defined permitting timelines and transparency • Potential for accelerated development outcomes OD6 believes the Quinns Project is well positioned to benefit from these initiatives, particularly given its: • Location on U.S. federal land • Critical mineral exposure (fluorspar) • Near-term development potential An initial discussion with a Fast-41 representative has occurred, with the Fast 41 Transparency program being most applicable for the project, with further consideration after submission of the baseline studies and POO. Next Steps - Permitting • biological and cultural surveys have commenced (2026 field season) • Finalise and submit initial phase POO application • Target CE approval and drilling as soon as practicable • Advance POO for expanded drilling • Progress bulk sampling permit applications 4 Forward Looking Statements Certain information in this document refers to the intentions of OD6 Metals, however these are not intended to be forecasts, forward looking statements, or statements about the future matters for the purposes of the Corporations Act or any other applicable law.
