[SMM Aluminum Express News] Metro Mining CEO and Managing Director Simon Wensley described 2026 as a pivotal year for the company, with a focus on maximising value from its expanded operations at the Bauxite Hills mine. “We’re really just trying to extract the maximum out of our 7 million tonne expansion,” he said, referring to the strategic expansion announced to the market at the end of 2022. Production was temporarily paused for seasonal maintenance but is expected to resume in early March. Wensley noted that the second half of the year is the “sweet spot,” thanks to optimal weather and tidal conditions. Looking further ahead, he highlighted the company’s strong reserve base and surrounding resources, which provide significant longer-term growth optionality.

Metro Mining is planning to increase production at its Bauxite Hills bauxite mining project in Queensland, raising its 2026 bauxite shipments to 6.5 million tonnes. Metro Mining reportedly shipped a record 2.3 million wet metric tons in the third quarter of this year, and its year-to-date shipments have reached 4.1 million wet metric tons, primarily driven by a 6% increase in bauxite production in August, with shipments reaching 753,101 wet metric tons that month.

On April 16, at the AICE 2025 SMM (20th) Aluminum Industry Conference & Aluminum Industry Expo - Alumina and Aluminum Raw Materials Forum, hosted by SMM Information & Technology Co., Ltd. (SMM), SMM Metal Exchange Center, and Shandong Aisi Information Technology Co., Ltd., and co-organized by Zhongyifeng Jinyi (Suzhou) Technology Co., Ltd. and Lezhi County Qianrun Investment Promotion Service Co., Ltd., Ding Long, General Manager of the Asia Market Department at Metro Mining Limited, Australia, provided an overview of Metro Mining and shared insights into the potential impact of Indonesia's new alumina production on China's alumina market. Indonesia's Alumina Capacity and Planning As of 2025, Indonesia has 11 alumina projects under construction or planned, with a total capacity of 25.5 million mt. Key Periods: 2024-2025: Approximately 8.5 million mt of new capacity (including production resumptions). After 2025: Over 10 million mt of new capacity is planned. Regional Distribution and Progress of Indonesia's Alumina Capacity Key Region: West Kalimantan (accounting for over 60% of planned projects). Projects with Rapid Progress: •Mempawah Alumina Refinery (3 million mt, with Phase 1 of 1 million mt commissioned in September 2024). •Nanshan Aluminum's Indonesia Base: Total alumina capacity has reached 2 million mt (1 million mt each for Phase 1 and Phase 2), with actual production reaching 1.91 million mt in 2023, accounting for 34.9% of the Southeast Asian market share. The new 2 million mt alumina expansion project is progressing as planned and is expected to be commissioned in 2026. •Jinjiang Group's PT BAP: Total planned capacity of 4.5 million mt/year. Phase 1, a 1 million mt/year alumina refinery, was officially commissioned in January 2025 and is entering the ramp-up stage; Phase 2 (2 million mt/year) is planned to commence in 2026. •A senior executive from Xinfa revealed that Xinfa is preparing to collaborate with local Indonesian enterprises to build power plants and aluminum enterprises. Feasibility studies are currently underway. East Hope Group to Invest in Indonesia's Aluminum Industry Key Region: West Kalimantan (accounting for over 60% of planned projects). East Hope Group: Will launch a 6 million mt alumina and 2.4 million mt aluminum project in West Kalimantan, Indonesia. The 6 million mt alumina project, located in Pontianak, West Kalimantan, will leverage the geographical advantages of being "near the port and near the mine" by constructing its own terminal and power plant, forming a closed-loop system of "bauxite mining - alumina smelting - aluminum production." The project will adopt the world's most advanced technology to ensure "ultra-low emissions" and green production, creating 3,000-3,500 jobs. The project will be constructed in three phases, with the first phase of 2 million mt capacity planned for commissioning in 2028. This will directly reduce domestic aluminum enterprises' raw material procurement costs by approximately 15% and mitigate supply chain risks associated with the over-concentration of bauxite sources in Guinea. Risks and Challenges in Investing in Indonesia's Alumina Industry Infrastructure Backwardness: Unstable power supply and high logistics and transportation costs in remote mining areas directly affect production efficiency and operating costs. Environmental Pressures: Stringent government environmental regulations require significant investment in environmental protection facility upgrades, such as waste (e.g., red mud) treatment to meet standards. Policy and Approval Risks: Projects require approval from both Indonesian and domestic governments, and policy adjustments may lead to project delays or terminations. Political and Economic Instability: Includes local separatism, exchange rate fluctuations, inflation risks, and policy uncertainties. Labor Skill Limitations: Alumina production requires skilled workers, but local labor skills are insufficient, and restrictions on foreign labor increase employment costs. Supply Chain Challenges: Poor management of bauxite mining may lead to supply disruptions, and inefficient logistics affect raw material transportation. Natural Disaster Risks: Indonesia is located in the Pacific Ring of Fire, and natural disasters such as earthquakes and tsunamis may threaten project safety. Australia Has a Fully Integrated Aluminum Industry But has surplus bauxite available for export to China. History of Bauxite Mining on the Weipa Plateau COMALCO commenced production in Weipa in 1963; signed its first long-term bauxite contract with China from Weipa in 2008; in 2018, Metro established the Hill Alumina Mine 100 km north of Weipa; Weipa Plateau bauxite grade: 50%+ alumina, 8%-12% silica; Metro has 130 million mt of resources; high-alumina bauxite, direct shipping ore; 2025 target to expand to 7 million mt annual production; Metro is Australia's only pure bauxite producer, not producing alumina to compete with its customers in the market. Northern Australian Bauxite Offers Significant Maritime Advantages Shipping time to China: 45 days from Guinea compared to 10 days from northern Australia. Australia's Bauxite Resources Additionally, it provided an overview of the 2024 alumina market disruptions. China's Alumina Trade China's alumina imports are expected to decline. China plays a crucial role in balancing the ROW alumina market. During periods of severe shortages, as seen in 2018, China became a net exporter. After Australia implemented an alumina export ban in 2022, China also increased its alumina exports to Russia. 4-6 mt of bauxite can produce 1 mt of aluminum Global aluminum demand is expected to grow by approximately 40% by 2030 Aluminum is a key metal for long-term renewable energy generation/storage, electric vehicles, and electrification. "By 2030, aluminum use in power generation will more than double that of copper" – IEA The aluminum required for the world's transition to green energy will exceed current power sector consumption by 50%. Solar PV power generation is expected to double in the next four years. By weight, aluminum accounts for 85% of the materials used in solar panels. By 2050, wind turbines will require 35 million mt of aluminum annually (4% of materials used). The EV industry will increase global aluminum consumption by 60% to 31.7 million mt by 2030.

Currently, the aluminum industry is at a critical juncture of profound transformation and rapid development. From an industrial dynamics perspective, the global aluminum industry is actively responding to the call for green development, accelerating the transition to cleaner production. From an industrial status perspective, China dominates the global aluminum supply chain. However, China's dependence on bauxite imports remains high. Against this backdrop, US tariff policies have had a significant impact on the global aluminum industry. Facing the challenges posed by US tariffs, Chinese aluminum companies are actively seeking countermeasures. On one hand, they are accelerating their layout in the high-end aluminum sector, increasing R&D investment, and driving product transformation towards higher value-added products, such as aviation plates and power battery foils, whose exports are gradually increasing. On the other hand, they are vigorously developing the secondary aluminum industry, as the energy consumption of secondary aluminum is only 5% of that of primary aluminum, aligning with green development needs. Some companies are using transshipment trade through third countries like Malaysia and Thailand to reduce tariff costs. Others are actively applying for green certifications, reducing export costs through digital carbon management systems, and establishing hydropower aluminum bases in the southwest to increase the proportion of green electricity usage, thereby meeting international market demand for green aluminum products.

Introduction to Metro Mining and Current Status of Alumina Capacity Expansion in Indonesia Metro Mining Metro Mining, an Australian company, focuses on bauxite development and exports. Its core asset is the Bauxite Hills mine in Queensland, Australia, with a resource reserve of approximately 150 million mt and an annual capacity of around 4 million mt of bauxite. Its major clients are alumina refineries in China, the Middle East, and Southeast Asia, with the Chinese market accounting for over 70% of its sales. The company employs open-pit mining and benefits from proximity to ports (simplifying logistics), with cash costs ranking among the lowest in the global bauxite industry. The bauxite has an average alumina content of about 50%, with low impurities (low silicon content), making it suitable for China's high-temperature Bayer process. The company uses reclamation techniques to restore mine ecology and has committed to achieving carbon neutrality in mining operations by 2030. In recent years, it has expanded its resource reserves through acquisitions and exploration while exploring cooperation opportunities in emerging bauxite regions such as Guinea and Indonesia. Current Status of Alumina Capacity Expansion in Indonesia Since 2020, Indonesia has banned the export of raw bauxite ore, mandating local value-added processing (promoting the construction of alumina refineries). The country plans to build over 10 alumina refineries by 2025, with annual capacity exceeding 20 million mt. Indonesia has abundant bauxite reserves (approximately 1.2 billion mt), but the grade is relatively low (alumina content of 40%-45%), necessitating reliance on imported high-grade ore (such as Metro's Australian ore) for blending to improve efficiency. Operational Projects: Projects led by Chinese companies such as Hua Chin Aluminum (part of China Hongqiao Group) and Huafon Group in Indonesia. In 2023, Indonesia's alumina capacity was about 5 million mt, accounting for 5% of the global total. Projects Under Construction/Planning: Investments by international companies such as Rusal and EGA are expected to make Indonesia the world's third-largest alumina producer by 2025 (after China and Australia). Potential Impact of Indonesia's New Capacity on China 1. Changes in Market Competition Landscape • Import Substitution Effect China currently imports about 3 million mt of alumina annually (mainly from Australia). The release of Indonesia's capacity may divert some demand, reducing China's reliance on Australian ore. • Price Pressure Indonesia's low-cost alumina (benefiting from cheap energy and labor) may impact domestic alumina prices in China, squeezing profit margins for high-cost domestic producers. 2. Industry Chain Adjustments • Strategies for Chinese Alumina Companies Accelerate capacity relocation to Indonesia (e.g., Nanshan Aluminum and Chalco's projects in Indonesia) to avoid raw material import tariffs and stay close to resources. Enhance domestic refinery technologies (e.g., low-carbon electrolysis, waste heat recovery) to reduce costs. • Changes in Bauxite Trade Flows Increased local processing demand in Indonesia may reduce its bauxite exports, forcing China to diversify its import sources (Guinea, Australia, Vietnam, etc.). 3. Long-Term Challenges and Opportunities • Challenges Risks related to Indonesia's policy stability (e.g., adjustments to export bans, tax fluctuations) and infrastructure bottlenecks (insufficient port and power supply). • Opportunities China-Indonesia capacity cooperation under the Belt and Road Initiative may foster regional aluminum industry clusters (integrated mining-alumina-aluminum-processing). 4. Response Strategies Sign long-term offtake agreements with major Chinese aluminum companies (e.g., Chalco, Weiqiao) to secure demand; explore equity stakes in Chinese alumina refineries to bind downstream. Provide high-grade Australian bauxite to Indonesian refineries (compensating for local low-grade ore), with supply agreements already in place with multiple Indonesian smelters. Promote "customized blending solutions" to help customers optimize alumina extraction rates; invest in digital logistics systems to improve China-Indonesia shipping efficiency. More in-depth analysis will be unveiled at the Alumina & Aluminum Raw Materials Forum on April 16, 2025! Norman graduated from the Department of Mineral Processing at Imperial College London and holds an EMBA from CEIBS in China. Before joining Metro Mining, Norman served as Sales Manager at Rio Tinto Aluminum, President of Asia Pacific at British Hardware, and President of Asia Pacific at U.S. Unisys. Currently, Norman is the General Manager of Metro Mining's Asia Market Department. AICE 2025 SMM (20th) Aluminum Conference & Expo As a platform focusing on the integration of aluminum mining, smelting, metal processing, and end-use consumption, the event will kick off at the Suzhou International Expo Center from April 16-18, 2025. Alumina & Aluminum Raw Materials Forum As one of the most important forums of AICE 2025, the event on April 16, 2025, will center on topics such as overseas bauxite layout, the global alumina market, energy conservation and carbon reduction in the aluminum industry, Chinese aluminum companies going global, fluid delivery systems, green transformation in the aluminum industry, aluminum price fluctuations, prebaked anode supply structure, graphitized cathode technology, carbon footprint in the aluminum industry, and domestic petroleum coke and calcined coke markets, bringing an unparalleled event to the aluminum industry in the spring of the year.

This week has been highly eventful for the upstream aluminium industry, especially the bauxite sector, which has dominated the headlines.

This week the upstream sector of the global aluminium industry witnessed many significant events. News of new highs, marginal misses, financial results, etc, have kept the industry on its toes.

SMM Morning Comment on Alumina: Recently, the weekly operating rate of alumina has rebounded slightly, and alumina supply has increased slightly. With the technological transformation and production cuts at aluminum smelters in Guangxi, Sichuan, and other regions, alumina demand has slightly decreased, and the previously tight alumina supply has improved compared to earlier periods. By the end of December, the alumina raw material inventory at aluminum smelters had rebounded slightly, while downstream restocking and purchasing enthusiasm weakened. The acceptance of high-priced spot alumina decreased, and with reports of some low-priced transactions, suppliers showed an increased willingness to sell. In the short term, spot alumina prices are likely to maintain a slight downward trend.
