Market Positioning and Competitive Analysis • Product Benchmarking ◦ The screened iron ore quality benchmarks against Rio Tinto's Robe River Fines, FMG's blended fines, and other Platts 58% index benchmark products. ◦ Similar to the operational models of nearby small trucking projects such as Mineral Resources' Wonmunna and Iron Valley. 9. Risks and Compliance Statements • Compliance Statements ◦ The resource estimate was completed by Widenbar and Associates, compliant with the JORC 2012 standard, with data verification including duplicate samples and standard sample analysis. ◦ Independent geologists Lynn Widenbar and Robert Jewson (company director) signed the report as Competent Persons. 10. Company Background • Macro Metals Limited ◦ ASX-listed under code M4M, with business covering mineral exploration, development, and mining services. ◦ Subsidiary MMS provides end-to-end services (mining, crushing, transportation, shipping) and holds a portfolio of iron ore and manganese assets. Summary The contract secures long-term revenue for Macro Metals through a dual profit model of technical services and mining operations (cost-plus + market rates), combined with the advantages of low-phosphorus ore blending and port logistics, giving it strong market competitiveness. The project has clear resource potential and a well-defined execution plan, and if approved and expanded successfully, it is expected to become a core growth driver for the company.

Currently, the price of magnesium metal has continued to pull back and is significantly lower than that of aluminum, making its cost-performance advantage reappear and its functional value prominent. The innovative development achievements of magnesium and magnesium alloys are increasingly growing, and innovative application cases of magnesium alloys are constantly emerging. They are expected to usher in new opportunities for expanded applications, especially in areas such as lightweight transportation, intelligent manufacturing, green construction, electronics and telecommunications, solid-state ESS, and medical health, where there is great potential to open up new application blue oceans. As a lightweight structural and functional material, magnesium metal will play an important role in promoting green, low-carbon, and high-quality development, demonstrating greater contributions. At this critical moment and important period, the 2025 Magnesium Industry Chain and Magnesium Market Forum will continue to be held. We will continue to fully leverage the platform's advantages, summarize the experience of previous events, enhance the promotion of this event, increase the participation of related industry chain enterprises, and strive to achieve greater results. SMM and Shang Magnesium Network cordially invite you to participate in the 2025 Magnesium Industry Chain and Magnesium Market Forum , which will be held from March 31 to April 2, 2025. Cross Ion (Hangzhou) New Material Technology Co., Ltd. will grandly attend this conference. We will synchronize with the times, aim at our goals, work diligently, and move forward with courage and determination! Click registration form to register for the conference immediately. We look forward to meeting you at the conference. Cross Ion (Hangzhou) New Material Technology Co., Ltd. is currently the only zero-emission ionic liquid electroplating aluminum industrialisation company in China. It possesses full-process technology related to ionic liquid electroplating processes and equipment, has a professional R&D team, and currently operates one automated production line and two sample lines. The company is committed to developing hydrogen-free, high-corrosion-resistant, zero-emission ionic liquid electroplating processes and equipment. The core team members are from Zhejiang University and have long been dedicated to innovative development in surface technology for the aerospace field. The company focuses on providing environmentally friendly surface treatment new technology—ionic liquid electroplating of high-purity aluminum and hard aluminum alloy technology—for aerospace, national defense, military, and industrial and civilian 3C fields. Currently, the company's high-purity aluminum electroplating technology has been successfully applied to the corrosion protection of key high-strength fasteners in the engines of China's Long March 2F manned space rockets, with corrosion resistance exceeding 1,000 hours of neutral salt spray testing without white rust. Electroplating high-purity aluminum on the surface of cast aluminum alloy and anodising it results in higher quality oxide film, more aesthetically pleasing appearance, lower cost, and higher efficiency. This disrupts the existing high-quality anodising process that requires aerospace aluminum alloy profiles and CNC machining, truly achieving carbon reduction, green environmental protection, and energy efficiency. This technology achieves zero emissions of wastewater and exhaust gas during the electroplating process and has unique advantages in surface treatment of active material substrates such as rare earth permanent magnets and magnesium alloys, meeting the engineering requirements for high corrosion resistance protection. The company provides zero-emission ionic liquid electroplating aluminum processing services and automated electroplating aluminum production lines, enabling high-purity electroplating of aluminum on various substrates (magnesium alloy, aluminum alloy, high-strength steel, rare earth permanent magnets, connectors, cast aluminum alloy, etc.). Main products: The company provides zero-emission ionic liquid electroplating aluminum processing services and automated electroplating aluminum production lines, enabling high-purity electroplating of aluminum on various substrates (magnesium alloy, aluminum alloy, high-strength steel, rare earth permanent magnets, connectors, cast aluminum alloy, etc.).
