Announcement PDF ASX Announcement 19 August 2026 ASX: OD6 1 OD6 METALS TO PURSUE US OTCQB QUOTATION Expanding U.S. investor access to OD6 as it advances the high-grade Quinn Fluorspar Project in Nevada amid 100% U.S. net import reliance HIGHLIGHTS • U.S. OTCQB Quotation: OD6 has commenced the process of seeking quotation of its ordinary shares on the OTCQB Venture Market in the United States, while retaining its primary ASX listing • Growing U.S. Investor Interest: The initiative follows increasing interest in OD6 and its Quinn Fluorspar Project from North American investors • Enhanced U.S. Market Access: OTCQB quotation is expected to improve visibility and trading accessibility for U.S. investors and broaden OD6's potential North American investor base • Strategically Important U.S. Critical Mineral: Fluorspar is included on the U.S. critical minerals list and the United States remains highly dependent on imported supply • Viriathus Appointed: U.S.-based Viriathus Capital LLC has been appointed as Financial Advisor to assist OD6 with the OTCQB quotation process, including application, certification and ongoing compliance requirements Managing Director Brett Hazelden, commented: "Commencing the OTCQB quotation process is a natural next step in OD6’s strategy as we increase our presence in the United States and advance the Quinn Fluorspar Project in Nevada. We are seeing increasing interest from North American investors in both OD6 and the strategic importance of fluorspar. The exceptional grades demonstrated at Quinn, together with its location in Nevada and exposure to a critical mineral for which the United States remains 100% net import reliant, provide a compelling foundation for increasing OD6’s visibility in U.S. capital markets. An OTCQB quotation has the potential to make OD6 more accessible to U.S. investors, broaden our shareholder base and increase awareness of Quinn as we continue to advance the Project. We are pleased to be working with Viriathus Capital, which brings specialist U.S. capital markets and OTCQB experience to assist OD6 through the quotation process" OD6 Metals Limited (ASX: OD6) (“OD6” or “the Company”) is pleased to announce that it has commenced the process of seeking quotation of its ordinary shares on the OTCQB Venture Market in the United States and has appointed U.S.-based Viriathus Capital LLC (“Viriathus”) as Financial Advisor to assist the Company through the quotation process. The proposed OTCQB quotation forms part of OD6’s broader strategy to increase its exposure to North American capital markets as the Company advances the Quinn Fluorspar Project in Nevada, USA. The initiative follows increasing interest in OD6 from North American investors and is intended to provide U.S. investors with greater visibility and accessibility to the Company’s ASX-listed ordinary shares. OD6’s primary listing will remain on the ASX. 2 Strategic Rationale for U.S. OTCQB Quotation OD6 considers the proposed OTCQB quotation to be a logical extension of the Company’s growing strategic exposure to the United States through the Quinn Fluorspar Project. Growing North American Investor Interest The Company has experienced increasing interest from North American investors as OD6 has advanced its U.S. critical minerals strategy and the Quinn Fluorspar Project. An OTCQB quotation is expected to provide U.S. investors with improved access to trade OD6 securities during North American market hours, while providing the Company with increased visibility across U.S. capital markets. Critical Importance of Fluorspar to the United States Fluorspar is included on the U.S. Government’s 2025 List of Critical Minerals, reflecting its importance to the U.S. economy and supply chains. The United States remains 100% net import reliant for fluorspar, with significant U.S. fluorspar mine production not reported since 1995. Fluorspar is the principal commercial source of fluorine and is used across a broad range of strategically important industrial applications. Acid-grade fluorspar is principally used to manufacture hydrofluoric acid, which is the primary feedstock for virtually all fluorine-bearing chemicals. Fluorine-based products have applications across advanced manufacturing, semiconductors, aluminium, uranium processing, batteries, defence and other high-technology industries. Increasing domestic sources of fluorspar therefore has the potential to contribute to greater security and resilience within U.S. critical mineral and industrial supply chains. About the OTCQB Venture Market The OTCQB Venture Market is operated by OTC Markets Group in the United States and is designed for entrepreneurial and development-stage U.S. and international companies. OTCQB provides qualifying international companies with access to U.S. investors while allowing those companies to maintain their primary listing on a recognised foreign exchange. Companies seeking OTCQB quotation are required to satisfy eligibility, disclosure, financial reporting and ongoing compliance requirements. OD6 will retain its primary listing on the ASX. Appointment of Viriathus Capital In connection with the OTCQB quotation process, OD6 has appointed Viriathus Capital LLC as its non-exclusive Financial Advisor. Viriathus is a U.S.-based capital markets advisory firm and an approved Corporate Broker Sponsor with OTC Markets Group. Viriathus will assist the Company with the OTCQB quotation process, including: • reviewing OD6’s eligibility for OTCQB quotation • assisting with preparation and submission of the initial OTCQB application • assisting with listing certification requirements • providing assistance in relation to U.S. disclosure and ongoing compliance requirements • liaising with OTC Markets Group and responding to requests and enquiries during the application process • providing U.S. capital markets advice relevant to the proposed quotation 3 Quinns Fluorspar Project U.S Strategic Advantage The Quinn Fluorspar Project, located in Nevada, USA, provides OD6 with direct exposure to a strategically important critical mineral within the United States. The Project's key attributes include: • location in Nevada, USA, one of the world’s established mining jurisdictions • a historical fluorspar mining district containing multiple known fluorspar occurrences • OD6 has now consolidated 100% ownership of 226 mining claims covering ~1,890 hectares • +20 Fluorspar occurrences, supporting a future hub-and-spoke development strategy • exceptionally high-grade fluorspar mineralisation demonstrated through OD6’s recent exploration and sampling programs • Multiple high-priority drill targets defined from integrated geological mapping, fluorine geochemistry, structural interpretation and historical drilling • 8km fertile mineralised corridor confirmed with additional high-grade fluorine anomalies identified outside known deposits • Low impurity mineralisation supports potential production of premium Acidspar (>97% CaF₂) and Metspar products following beneficiation • Permitting program underway, including environmental baseline, archaeological studies and preparation of drilling and bulk sample approvals • Metallurgical testwork advancing with optical sorting and beneficiation studies to optimise premium product recoveries • Potential Gold Upside identified in soil sampling across Mammoth, Horseshoe and Dress Circle Together, these results reinforce OD6's view that Quinn has the potential to emerge as a strategically significant domestic source of high-grade fluorspar in a U.S. market that remains 100% net import reliant.
