Cautionary Statement Regarding Exploration & Development, Values & Forward-Looking Information The tenements comprising the Company’s projects (“Projects”) are at various stages of exploration and development and potential investors should understand that mineral exploration and development are high-risk undertakings. There can be no assurance that exploration and development of the Projects, or any other tenements that Metallium may acquire in the future, will result in the discovery of an economic deposit. Even if an apparently viable deposit is identified, there is no guarantee that it can be economically exploited. Specifically, investors are cautioned that the Projects have no reported mineral resources or ore reserves and that the proximity of the Projects to any deposit and any geological similarities with that deposit are no guarantee that the Project will be prospective for an economic reserve. It is a requirement of the ASX Listing Rules that the reporting of exploration results in Australia comply with the Joint Ore Reserves Committee’s Australasian Code for Reporting of Mineral Resources and Ore Reserves (“JORC Code”). Investors outside Australia should note that while exploration results pertaining to the Projects comply with the JORC Code, they may not comply with the relevant guidelines in other countries and, in particular, do not comply with National Instrument 43 101 (Standards of Disclosure for Mineral Projects) of the Canadian Securities Administrators (the “Canadian NI 43 101 Standards”). 2 Illustrative Economics Disclaimer This document may include conceptual illustrations and indicative assumptions regarding potential business model economics.

The Industry’s Technology Problem Legacy Metal Processing Tech is Costly and Unsustainable ✓ Traditional methods: High-energy smelting (1,000°C+) or kiln-based heating over long time periods, low yields. PYROMETALLURGY Energy intensive, fossil-fuel powered ✓ Environmental cost: Legacy processes emit large volumes of CO₂ and typically generate hazardous waste. HYDROMETALLURGY Chemical intensive, embedded emissions ✓ Economic cost: Predominantly acid-based / chemical heavy with significant energy and management costs. SUB-ECONOMIC OR DO NOT WORK Legacy techniques unsuitable for certain ores and wastes ✓ Legacy technology: Many industry-standard equipment (e.g. centuries-old rotary kilns) remain inefficient, underscoring a lack of innovation in the sector. The industry is ripe for a cleaner, more efficient solution … 6 Metallium’s Elegant Solution: Flash Joule Heating Metal Bearing Feedstock FJH Process Recovered Metal Products Recovered Metal Chlorides Metal-rich Feedstock + Proprietary Catalyst + Reactant ULTRAFAST HEATING + PROPRIETARY CHEMISTRY Ultrafast Heating We apply a short burst of electric energy to crushed ore or waste. The feed heats in very short timeframes. Proprietary Chemistry Reactive chemistry helps vaporise target metals as chlorides. Metals are released as vapours and condensed into saleable metal chlorides. → No acid leaching → No multi-stage smelting → No harmful tailings. What It Enables FJH can unlock value from difficult materials like lithium concentrates, rare earth concentrates and intermediates, red mud tailings, and e-waste - faster and more economically than traditional methods. Designed for rapid deployment and modular scalability - enabling fast setup across distributed sites, with minimal permitting and infrastructure requirements. Net result: Single-step, low-carbon process to extract metals faster, with higher efficiency and lower reagent use than incumbent technologies. Positioned to industrialise FJH - a disruptive new pathway for critical and precious metals recovery 7 Commercial Readiness Texas Technology Campus Metallium’s U.S. Technology Campus will house our first commercial plant and serve as a hub for ongoing R&D and future expansion. Prime Location in Houston Industrial Corridor Strategic location offers direct access to Interstate 10, the Houston Ship Channel (major port), and is within a 40-minute drive of central Houston, ensuring efficient logistics and access to suppliers/customers. 8 Primary Focus Feedstocks – High-Value Materials First Gallium / Germanium / Indium (semiconductor or refinery scrap) Critical and Precious Metals with highly compelling economics ✓ Gallium, Germanium, Indium - the hidden semiconductors of AI, chips, and fibre optics. Access to ultra-rich feed: e.g. Ga/Ge scrap very high in metal value. Gold-Rich E-Waste (PCBs) ✓ Gold from e-waste - the richest of urban mines. Tested material with up to 550 g/t Au + 40% Cu + 14% Sn Mineral Concentrates 9 Engagements with major mining and chemical companies underway ✓ Rare Earths such as Nd, Pr, Dy, Tb - the magnets of electric motion, mobility, clean energy, and defence. Our Business Model: Two Engines of Value How do we monetise this moat? Through two core Business Units URBAN MINING (WASTE RECYCLING) 10 Technology Metals: Electronic Waste: Rare Earth Elements Red Mud (REEs) (Bauxite Residue) Gallium, Germanium, Indium, Tin, Antimony Gold, Copper, PGE -rich Printed Circuit Boards Nd, Pr, Dy, Tb Alumina, Ga, REEs, Titanium BUSINESS MODEL BUILD-OWN-OPERATE: Metallium will source feedstock, operate its own facilities, & capture full value from recovered metals PRODUCTS Metal chlorides or derivatives – Essential for semiconductors, photovoltaics etc. INDUSTRIAL PARTNER(S) MINERAL PROCESSING (MINING PROJECTS) Metal chlorides or derivatives incl. Gold Chloride – Highly saleable LICENCING: Provide equipment & services to miners / processors. Monetise via Licensing & Production Royalties Various optionality for metal chlorides or more refined intermediates Metallium’s Focus Metals Align with U.S. Strategic Priorities U.S. Department of Energy – 2025 Draft Critical Materials Assessment Critical Metals • REEs, Sb, Ga, Ge, In: DOE-designated critical. • Used in semiconductors, AI, clean energy, defence etc • All are 90–100% import-reliant in the U.S. Aligned with U.S. Policy and Funding Mandates • Supports onshoring & de-risking of critical metal supply. • Potential for DoE / DoW funding, offtake, and strategic procurement.

U.S. DEFENCE IMPACT: ✓ Export licenses issued selectively — demonstrating geopolitical leverage over supply. ✓ REEs used ubiquitously in Military tech ✓ 2022: Pentagon halted F-35 deliveries after finding a Chinesemade magnet in a critical part BOTTOM LINE: ✓ Production resumed only after a national security waiver → exposing U.S. weapons programs. The U.S. is one geopolitical decision away from a critical metals supply shutdown. NO U.S. / WESTERN DOMESTIC SAFETY NET: ✓ No U.S. capacity for heavy REE refining ✓ Only one Western NdFeB magnet producer ✓ Heavy reliance on Chinese downstream processing 13 CURRENT CRISIS — 2025: Decoupling from China: Building the Future of REE Processing in the U.S. Binding Agreement with Ucore Rare Metals (TSXV: UCU) - Sep 2025 ✓ Strategic Synergy – Integration of FJH with Ucore’s RapidSX , enabling diverse REE feedstocks to be processed into separated oxides in U.S. (vs. China) ✓ Natural Flowsheet Fit – FJH upgrades feedstocks into clean chlorides, directly compatible with RapidSX , cutting steps, costs, & expanding acceptable inputs (incl. magnet scrap, tailings) ✓ Strategic Growth – Provides entry into U.S. magnet recycling, heavy REEs (Dy, Tb), and joint pursuit of DoW/DoE funding ✓ Outcome – Establishes a sovereign U.S. pathway to separated REE oxides, breaking dependence on China 14 U.S. National Commercial Sites: Rollout Plan Strategic Multisite Deployment Plan – Pre-Permitted U.S. Network Anchored in Texas 15 ▪ Texas Hub Secured: Pre-permitted anchor site in Houston for near-term commissioning. ▪ Expansion Pipeline: Additional sites secured/shortlisted near e-waste aggregators and industrial partners. ▪ Site Criteria: Access to feedstock, partners, and logistics corridors. ▪ Deployment: Fixed hubs plus mobile modular units for flexibility. ▪ Strategic Rationale: Geographic redundancy, U.S. reshoring alignment, and fast-track to scale recovery capacity nationwide.
