Butcherbird Stage 1 Pilot Grizzly/Jaw Crusher Process Upgrade: Mineral Sizer /Rolls Crusher Examples of Mineral Sizers in use in similar settings to BBX 10 Butcherbird Expansion Project - Process Plant Reference: KISA Washing Circuit: Clay removal from laterite feed • The logwasher is an agitated scrubber which acts to break up and wash clays out of the feed material. • The clay contains very little manganese so its removal upgrades the concentrate to approach the target Mn grade for sale. • The process uses water as the only reagent making the tailings environmentally benign. 11 Clays and other impurities are scrubbed by rotating intermeshing paddle shafts and washed by counter-current water flow. Reference: Heavy Media Drum – Malvern Engineering Dense Media Drum: Improved grade & recovery • Separate ore from gangue based on density not optics/colour • Eliminate separation challenges associated with imperfect washing and ore presentation. • Widely used process technology – low risk approach suited to larger scale operation. Low-density/lighter waste shale particle High-density/ heavier manganese product particle Dense media Separation (DMS) is a mature process technology used in a wide range of mineral processing plants including iron ore and manganese to separate lighter waste material from denser ore material by floating the waste in a ferro-silicon slurry to create separate product and waste streams. 12 Butcherbird Expansion Project - Process Plant • Northern Australia Infrastructure Facility (NAIF) to provide up to AU$50 million senior debt facility for Element 25’s Butcherbird Manganese Expansion Project2. • Butcherbird development based on a 1.1 Mtpa manganese concentrate operation and delivers outstanding metrics 1. • Manganese concentrate to be sold to steel industry partners and provide feedstock for E25’s planned HPMSM facility in Louisiana, USA. • Butcherbird Expansion plan is fully approved under WA Regulatory Framework3. • NAIF to act as the sole senior secured lender to the project - the balance of funds to be sourced from financiers including offtake prepayment, subordinated debt and royalty financing as potential mechanisms.

Breaking the Chinese Supply Chain Dominance • Refined manganese (HPMSM) capacity is heavily concentrated with >95% of refining capacity located in China. • Concentrated supply creates supply risk for critical raw materials used in batteries including manganese. • Customers are seeking alternative sources of long-term manganese supply. • Element 25 provides a long-life mine and a future facing processing technology. South Africa China Other Manganese Ore Refined Manganese Improved, Cost-Competitive, Cleaner Process Technology Fewer Reagents Lower Emissions No Waste Residue The Element 25 Process brings significant changes & improvements: E25 technology enhances ESG profile by: • Eliminating waste residues. • Eliminating toxic Reagents like fluorine. • Increased efficiency and lower costs. • Faster permitting due to lower impacts. Reference: Company ASX Release Dated 16 February 2023 21 Global Refining Capacity in the Longer Term ** • Design one, build many approach to development. • E25 manganese concentrate is a very stable, easily transported feedstock. • Allows location optionality for the processing facility. • Multiple potential sites being explored.

Australian manganese concentrate supplying customers in traditional ferro-allow markets and planned battery grade manganese(HPMSM) production for US lithium-ion battery manufacturers. Steel Li-Ion Batteries 23 Global EV Sales Outlook Remains Strong 24 EV market share continues to grow: • Electric vehicles to reach over 50% market penetration by 2030 according to Bloomberg NEF. • Short term policy settings have reduced uptake in some markets but medium-term demand forecasts remains bullish. • Critical raw material supply remains a key geopolitical challenge with near total dominance by China of key raw materials including manganese. • Battery grade manganese expected to see strong demand due to increase in electric vehicle sales and shift to higher manganese cathode materials. Near-term global sales outlook for electric and fuel-cell vans, trucks and buses Global passenger-vehicle sales by drivetrain Reference: Umicore 2023 Transition to Higher Manganese Battery Cathodes Reduced nickel and very low to no cobalt content. LMFP, LMR, LMNO and NMX cathode chemistries offer improved safety, higher energy density, reduced cost per kWh and greater supply chain flexibility. High Mn means reduced reliance on Ni and Co: Why LMR batteries will change the outlook for the EV market 25 Louisiana Battery Grade HPMSM HPMSM DoE MESC Grant - Supporting Local Raw Material Supply Local Supply Chain • Process and supply chain developed to maximise U.S. industry involvement. • Working with partners GM and Stellantis to supply low carbon HPMSM for EV batteries. • All reagents sourced locally from established suppliers. • Site located close located adjacent to acid recycling facility. • Solid residues as co-products will be placed into local industries targeting zero waste. • Low carbon, circular economy approach.
