(SMM), Feng Chundi, Expert of the SMM Industry Research Institute, and Wu Tao, SMM Copper & Tin Overseas Marketing Manager, visited Chambishi Copper Smelter Limited (CCS) for exchange and survey, where they received warm hospitality from CCS leadership. During the visit, both parties engaged in pragmatic communication based on their respective core businesses. Leveraging its core strengths in non-ferrous metal price index R&D, industry chain big data monitoring, copper market analysis, in-depth industry research, and global non-ferrous resource connectivity, SMM shared insights on international copper market operating logic and price trend analysis, in the context of the current global copper smelting supply-demand pattern, raw material procurement landscape, and TC fluctuation trends. As a key copper smelting producer outside China, CCS provided a detailed introduction to its production and operation status, smelting process advantages, capacity release pace, raw material procurement, and product exports layout, elaborating on practical experience of ex-China copper smelters in production management, cost control, green production, and localized operations. Meanwhile, both parties exchanged views on common industry topics including development pain points of copper smelting outside China, raw material supply security, finished product circulation and trade, industry policy changes, and low-carbon smelting development trends. They also reached preliminary consensus on future directions such as industry chain information sharing, market data sharing, joint market analysis, and industry resource coordination, laying a solid foundation for deepening regular exchanges and promoting high-quality collaborative development of the copper smelting industry chain. Introduction to Chambishi Copper Smelter Limited (CCS) Chambishi Copper Smelter Limited (CCS) is the first large-scale modern pyrometallurgy copper smelting enterprise invested, fully independently designed and constructed by China outside China. Located in the Zambia-China Economic and Trade Cooperation Zone, the company has 170 Chinese staff and 1,600 Zambian employees. CCS has consistently focused on its vision of "building an evergreen, world-class smelter," upholding the corporate spirit of "self-transcendence, continuous breakthroughs, and pursuit of excellence," benchmarking against first-class standards with meticulous craftsmanship, and continuously strengthening and optimizing enterprise management, with its comprehensive competitiveness steadily improving. As of the end of 2024, the company had produced over 3.3 million mt of copper products and 8.7 million mt of sulphuric acid, with cumulative sales revenue of approximately $21 billion, effectively driving local economic development in Zambia and becoming a shining pearl along the Belt and Road! Enterprise History and Development Achievements (Pursuing Excellence, Benchmarking Against the Best and Forging Ahead) To extend the industry chain and retain more added value locally, in 2006, China Nonferrous Metal Mining (Group) Co., Ltd. partnered with Yunnan Copper to introduce the advanced ISA copper smelting process to Zambia, with shareholding ratios of 60% and 40%, respectively.

Global new energy and AI industries exhibited high prosperity, coupled with optimistic demand during the seasonal consumption peak. Voices from Various Parties A Huaxi Securities research report stated that external geopolitical risks persist at the current juncture, and market risk appetite may affect short-term market fluctuations. AI remains a key investment theme in the near term, with attention on domestically produced computing power and computing power leasing driven by supply-demand imbalance, as well as optical module and fiber optic cable segments with strong earnings certainty. Computing power supply-demand imbalance is intensifying, with computing power consumption expanding sharply and the three major cloud providers collectively raising prices. On one hand, the current supply-demand imbalance reflects robust demand in upstream chips and computing power leasing industries, with enhanced bargaining power driving price increases, benefiting domestic AI chip and computing power leasing producers. On the other hand, rising AI service costs will be transmitted to downstream application development, potentially accelerating downstream industry consolidation and improving computing power utilization efficiency. Changjiang Securities believed that geopolitical conflicts were accelerating the restructuring of global supply chains, enhancing China's irreplaceability as the "world's factory," and that related export chain and manufacturing leading assets may command a "scarcity premium." In terms of allocation, regardless of whether the Middle East conflict fluctuated, three main themes should be firmly pursued. First, the AI trend that conflicts could hardly alter — focusing on AI infrastructure such as computing power, storage capacity, and power equipment, as well as "HALO" asset opportunities. Second, the urgency of conflicts accelerating the energy revolution — focusing on new energy sectors such as lithium battery and hydrogen energy, as well as resource commodities including non-ferrous metals, oil, and coal. Third, sectors at cyclical bottoms where earnings were expected to gradually improve, such as chemicals, steel, and condiments. Data showed that the CSI A500 Index, closely tracked by A500 ETF South China, covered high-quality large- and mid-cap leading enterprises in A-shares, evenly distributed across core areas such as emerging manufacturing and consumption upgrading, with a focus on new quality productive forces. Investors could gain exposure through A500 ETF South China and its feeder funds in one step. A Huatai Securities research report believed that, with the rapid increase in demand for 800G and 1.6T optical modules in recent years and the approaching 3.2T era, the development opportunities for upstream core materials of optical modules were promising. It systematically reviewed the growth logic of two major industries — InP substrates and thin-film lithium niobate. InP substrates, as upstream core raw materials for optical chips, benefited from the rapid boost in demand from optical chip producers, with the industry showing an undersupply trend. Modulators made from thin-film lithium niobate, leveraging advantages such as low power consumption and high bandwidth, were expected to enter an adoption window in 3.2T pluggable solutions in the future, with broad growth potential across the industry chain. A Shanxi Securities research report indicated that NVIDIA made a $2 billion strategic investment in Marvell to cooperate on expanding the NVLINKFusion ecosystem. On March 31 local time, NVIDIA and Marvell announced a strategic partnership to connect Marvell with NVIDIA's AI factory and AI-RAN ecosystem through NVIDIA NVLINKFusion. Marvell would provide customized XPUs and NVLINKFusion-compatible expansion networks, while NVIDIA would provide supporting technologies, including Vera CPU, ConnectX NICs, Bluefield DPU, NVLINK interconnects, and SpectrumX switches, as well as rack-scale AI computing. Marvell is one of the world's leading ASIC custom service providers, with clients including AWS, Microsoft, and Google. It is a major global supplier of optical module DSP and EIC, and has focused on CPO deployment through the acquisition of CelestialAI. We believe that NVIDIA's strategic investment in Marvell is expected to enhance Marvell's design capabilities in memory semantics, high-speed SERDES, and super-node systems, and to facilitate the expansion of the NVLINKFusion ecosystem. NVIDIA's NVLINK Scaleup technology encompasses an overall solution covering NVLINK SERDES, NVLINK chiplets, NVLINK switches, and rack-scale expansion architecture (including NVLINK SPINE, copper cabling systems, innovative mechanical architecture, power supply, and liquid cooling technologies). NVIDIA unveiled a complete copper-connected rack-scale solution at GTC 2026, including Rubin NVL72, Rubin Ultra NVL144, LPX 256, and ETL 256. Shanxi Securities believed that Marvell's participation is expected to expand the addressable market for copper connectivity. NVIDIA has positioned CPO as one of the most important transformations in Feynman-generation Scaleup technology, and combined with Marvell's silicon photonics technology, we believe the CPO penetration rate is expected to gradually increase. Soochow Securities' research report commenting on Fujida noted: a leading player in China's RF connector industry. The company specializes in the R&D, sales, and services of connectors, cables, cable assemblies, and microwave components, holding a leading position in China and non-China markets. Since its establishment in 1998, the company has been deeply engaged in the RF interconnect field. Backed by AVIC Optronics (its controlling shareholder), it has gradually expanded from traditional general-purpose RF connectors to high-end new product categories, including RF cables (aerospace applications), advanced ceramic products (chip integrated packaging applications), and RF links (active and passive microwave components). In 2025, the company achieved revenue of 881 million yuan and net profit attributable to the parent company of 78 million yuan, up 15.5% and 52.0% YoY, respectively. The company has positioned itself in five core tracks, with broad prospects for high-end connectors: 1) Demand in the defense informatization sector remained strong, with new products showing considerable potential. 2) The civil aerospace satellite sector has become a new growth engine. 3) The semiconductor equipment industry urgently needs high-end RF/electrical connectors. 4) The domestic supply chain for high-end electronic measurement instruments is embracing opportunities. 5) High-speed copper cables and quantum communication cable products are benefiting from the data center construction boom. Large-scale growth in data center infrastructure is boosting high-speed transmission products to gradually evolve toward system-level solutions. The company's high-speed copper cables have achieved product category expansion around 400G components, reaching an internationally leading level; meanwhile, in the quantum communication field, the company has deployed cryogenic superconducting cables, achieved initial small-batch supply, and is expected to gradually achieve commercialization.

SMM April 21: As the anti-involution policy continued to advance, the second round of coke price hikes was officially implemented. This, combined with persistently tight spot supply and demand, capacity constraints caused by Daqin Railway maintenance, the highlighted coal substitution advantage driven by high oil prices, and incremental demand from continued increases in hot metal production, created multiple positive factors that drove the coal mining sector to a two-day winning streak. Specifically, on the supply side, the Daqin Railway spring concentrated maintenance restricted north-to-south coal transportation capacity, inventories continued to decline, and the implementation of coke price hikes further transmitted cost support, pushing coal prices steadily upward. On the demand side, a stronger-than-usual off-season pattern emerged, with hot metal production continuing to edge up, coupled with significant YoY and MoM increases in daily consumption at coastal power plants. Restocking demand from the construction materials and other industries was released ahead of the Labour Day holiday, and with power plant inventories at low levels, seasonal restocking demand was activated early. In addition, tensions in the Middle East pushed up international oil prices, highlighting the economic advantage of coal-fired power, while the defensive attributes of the coal sector attracted some capital inflows, jointly driving the sector higher. As of the close on April 21, the sector gained 2.27%, with individual stocks performing actively. Gansu Energy Chemical, Huayang New Material Technology, Yankuang Energy, Shaanxi Coal Industry, and Lu'an Clean Energy led the gains. Futures market: As of the daytime close on April 21, ferrous metals mostly rose, with coking coal up 1.53% and coke up 2.42%. Spot market Hot metal production is expected to continue edging up this week On April 15, the blast furnace operating rate of the 242 steel mills tracked by SMM rose WoW. The sample steel mills' daily average hot metal production increased WoW. Last week, according to the latest SMM survey, no new blast furnace maintenance was reported, and a total of 2 blast furnaces resumed production, mainly concentrated in Shanxi. Currently, blast furnace profits were under pressure, and most steel mills produced normally as planned. The pace of maintenance and production resumptions remained generally stable, with hot metal production staying relatively steady. Looking ahead to this week, hot metal production is expected to continue edging up. Spot market: On April 21, the Linfen low-sulphur coking coal price was quoted at 1,530 yuan/mt. The Tangshan low-sulphur coking coal price was quoted at 1,550 yuan/mt. The nationwide average price of first-grade metallurgical coke (dry quenching) was 1,845 yuan/mt. The nationwide average price of quasi-first-grade metallurgical coke (dry quenching) was 1,705 yuan/mt. The nationwide average price of first-grade metallurgical coke (wet quenching) was 1,490 yuan/mt. The nationwide average price of quasi-first-grade metallurgical coke (wet quenching) was 1,400 yuan/mt. Coking coal market: Production at some mines that had previously cut production recovered somewhat, but major mines were still affected by safety inspections, and the incremental supply of coking coal remained limited. Moreover, futures rallied, market sentiment warmed notably, stimulating some coal grades to stabilize and rebound. In the short term, coking coal prices may hold up well. Coke market: In terms of supply, coke enterprises' per-mt profitability has recovered, production enthusiasm was moderate, shipments were relatively smooth, and in-plant coke inventory remained at low levels. Demand side, steel mills maintained strong production enthusiasm, hot metal production edged up, providing solid just-in-time procurement support for coke. Additionally, with the Labour Day holiday approaching, some steel mills released pre-holiday restocking demand. Overall, the coke supply-demand structure remained tight, and the coke market may hold up well in the short term. Institutional Views A Datong Securities research report showed: on coking coal, driven by downstream restocking and coke price hike expectations, port coking coal prices rose, while mine-mouth coal prices showed some divergence. At ports, Shanxi-origin coking coal warehouse-pickup prices at Jingtang Port rose WoW, while mine-mouth prices generally showed a stable-to-declining trend. Internationally, Australian Peak Downs hard coking coal CFR China prices were flat WoW. In the short term, with continued growth in hot metal production, sentiment boost from coke price hikes being implemented, and downstream restocking demand release, the coking coal market may see slight upward momentum. A Shanxi Securities research report noted: currently, Daqin Line maintenance-related destocking and high landed costs of imported coal supported coal prices. Power plant daily consumption was at seasonal lows, while chemicals, steel mills, and other industries drove coal demand. Attention should be paid to the sustainability of just-in-time procurement from non-power industries and the summer electricity consumption peak after May. Investment recommendation: high uncertainty from US-Iran conflicts corresponds to high volatility, but oil prices are unlikely to decline significantly in the short term. Recovery signals have been confirmed, coal PPI is about to turn positive, coal prices are expected to rise, and coal stocks are poised for a Davis Double Play. A Guohai Securities research report suggested that, from a broader perspective, the supply-side constraint logic for the coal mining industry remains unchanged, while demand may experience periodic fluctuations, with prices also showing certain oscillations and dynamic rebalancing. From the long-term industry development trend, the aforementioned driving factors still exist, and coal prices still have upward momentum over the long term. The process may be tortuous, but the direction should be clear. Leading coal enterprises have high asset quality, abundant cash flows on their books, exhibiting "five highs" — high profitability, high cash flow, high barriers, high dividends, and high margin of safety. Since 2025, multiple central and state-owned coal enterprises have initiated share buyback and asset injection plans for their publicly listed firms, also releasing positive signals, demonstrating confidence in coal enterprise development, and enhancing corporate growth potential and stability. A Guangda Futures research report analyzed: Coking coal: supply side, most mines at production areas operated largely normally. There were reports that Mongolian coal throughput decreased due to factors such as fuel shortages. Recently, downstream buyers moderately restocked raw material coal, and overall inventory continued destocking. Demand side, steel mills maintained high hot metal production, with a preference for coke procurement. The second round of coke price increases was implemented, and coking enterprises restocked some coal grades with higher cost-effectiveness. Coking coal futures are expected to hold up well in the short term. Coke: Supply side, coking enterprises in some regions were constrained in operations due to government ultra-low emission retrofit requirements. Coking enterprises saw good shipments, and coke inventory mostly remained at low levels. Demand side, steel mills had a relatively strong willingness to produce, and mainstream steel mills accepted the second round of coke price increases. Transportation restrictions emerged in some regions, and steel mills experienced continuous destocking, with high procurement enthusiasm. Coke futures are expected to fluctuate upward in the short term. Southwest Futures stated: In the short term, changes in the Middle East situation may still have sentiment impact on futures prices, but the impact on the actual supply-demand pattern of coking coal and coke is relatively small. Coking coal side, production at some mines in major producing areas was affected, but the impact on production was limited. Demand side, the online auction atmosphere improved recently, and quotes for some coal grades were raised. Coke side, some coking enterprises currently cut production, but the change in supply was relatively small; demand side, national daily hot metal production may continue to rebound, and demand expansion provides support for coke prices; the second round of spot coke price increases is being implemented. From a technical perspective, coking coal and coke futures may continue to move sideways in the medium term. Strategy-wise, investors may watch for buying opportunities at low levels and pay attention to position management. Recommended reading:

Shanghai Metals Market (SMM) is thrilled to announce that our 2026 SMM Global Lead-Acid Battery Supply Chain Industry Conference is scheduled to take place in Ho Chi Minh City, Vietnam, during November 12-13, 2026！

This week, the sodium-ion battery industry operated steadily overall, with industry prosperity continuing to rise. On the technological front, key performance metrics such as high safety, long cycle life, and low cost continued to achieve breakthroughs, laying a solid foundation for large-scale applications. With policy and industry working in synergy, upstream and downstream projects along the industry chain advanced steadily. Supporting infrastructure across materials, battery cells, system integration, and end-use applications continued to improve, with capacity deployment gradually materializing. The pace of scenario validation in energy storage, telecom backup power, and other fields accelerated, and market recognition of sodium-ion batteries' substitution and complementary effects increased. Overall, the industry is demonstrating a development trend characterized by **accelerating technological iteration, broadening application scenarios, and an increasingly mature industry chain**. The industrialisation of sodium-ion batteries continues to advance, with a promising medium and long-term development outlook.

Over the past half-century of industrialisation, the global seaborne iron ore market took shape and solidified into a "duopoly" supply structure dominated by Australia's Pilbara region and Brazil's Carajás and Iron Quadrangle regions. However, with the evolution of macroeconomic cycles, the structural shift in China's economic growth momentum, and the historic imperative for the global steel industry to transition toward low-carbonisation and green development, this traditional supply landscape is undergoing an unprecedented reshaping. On November 26, 2025, as the first commercial vessel loaded with Simandou iron ore slowly departed Mabariya Port for the open sea, Guinea's Simandou iron mine officially commenced production. As the world's largest and highest-quality greenfield iron ore project, this milestone signalled the gradual rise of the African continent—long relegated to a secondary position—as an important emerging force in the global ferrous metals market. Why should we pay attention to the African market? The African continent's iron ore resources are regarded as the third most important region for global iron ore supply, after Brazil's Carajás region and Australia's Pilbara region. The sheer scale and high grade of its resources account for 13.8% of global iron ore resources. It is also set to be the primary supply-side growth driver over the next five years. Therefore, changes in African iron ore will long remain a key market determining international iron ore prices . This article provides a comprehensive analysis of the current status and landscape of African iron ore and select steel markets, offers an in-depth discussion of future development trends, and presents a data-driven outlook on market changes. I. Global Iron Ore Background According to SMM survey data, as of 2025, global iron ore production is estimated at approximately 2.472 billion mt. Of this, Africa contributed approximately 95 million mt, accounting for nearly 4% of total global production. With the successive commissioning of various large-scale mining projects, Africa's iron ore capacity is expected to double by 2030, reaching a scale of nearly 259 million mt. Assuming no production cuts in other regions, Africa-produced iron ore's global market share is expected to rise to nearly 10%, while the global iron ore market's oversupply is estimated to increase to approximately 220 million mt. (Chart-1: Balance Sheet) Although the international iron ore market has already entered a prolonged cycle of loose supply, the substantive supply shock from African iron ore is expected to materialise gradually only over the next five years. In the short term, based on an estimated 15 million mt of new African shipments in 2026, their outstanding high-grade characteristics are expected to quickly meet steel mills' current demand for low-carbon ore blending, allowing the market to absorb them smoothly, with a relatively mild impact on absolute international iron ore prices. The key point to watch will be from 2028 to 2029. As railway, port, and other infrastructure facilities still under development in Africa are fully connected, the surge in high-grade iron ore production will exert heavy downward pressure on the right side of the global iron ore cost curve. This will not only systematically push down the price center of iron ore but also trigger intense structural squeeze; that is, the survival space for low-grade, high-cost mines will be significantly compressed. This price downcycle is expected to persist through 2028. When international ore prices fall below the marginal cost support level of $90/mt, non-mainstream small mines on the far right of the cost curve will be forced to shut down and exit the market. By then, the global iron ore supply landscape will have completed a new round of reshuffle, re-forming a multi-oligopoly ecosystem dominated by ultra-large, low-cost mines (including new African mines), supplemented by quality mid-sized mines. (Chart-2: Price Forecast Curve) II. African Market Current Landscape: South Africa as the Dominant Leader with Multiple Strong Players, West African Countries Actively Expanding Having analyzed the foundation of the global iron ore market landscape, the focus will now shift to the overall situation in Africa. As the primary driving force behind supply growth over the next five years, Africa's iron ore production is concentrated in West Africa and South Africa. Currently, Africa is dominated by three major countries. Among them, South Africa is the largest producer, with production reaching approximately 67 million mt in 2025, and its export shipments firmly hold an absolute dominant position of approximately 65% of Africa's total iron ore exports. However, constrained by potential structural limitations, the future organic growth potential of South Africa's iron ore industry is relatively limited. As major iron ore projects in other emerging resource-rich African countries successively come into production and release capacity, South Africa's share in Africa's overall export market is expected to face sustained contraction. Next is Mauritania, as Africa's second-largest iron ore producer, with production of 15 million mt in 2025 and export volumes of approximately 12 million mt, accounting for 12% of the African market. Mauritania borders the Atlantic Ocean, possesses abundant high-grade iron ore deposits deep in the Sahara Desert, and enjoys exceptionally favorable geographic location and mineral resources. Moreover, it is within close proximity to European and Middle Eastern markets that urgently need green industrial raw materials, providing it with unique advantages for absorbing the global transfer of green metallurgical capacity. It will be a highly promising iron ore supplier in the future. In addition, Sierra Leone, as another important supply hub in the region, also has an expected production of 12 million mt in 2025, holding a stable share of approximately 12% in the African export market. Chinese-invested iron ore mines within the country are actively expanding their operations. Macro trade flow perspective, based on full-year 2024 trade data, the proportion of African iron ore shipped to the Chinese market was relatively low compared to traditional mainstream mining regions, accounting for only about 60%, while the broader Asian market encompassing China, Japan, and South Korea collectively absorbed approximately 70% of African iron ore shipments. Meanwhile, Western European countries represented by the Netherlands and Germany constituted the core secondary shipping destination for African iron ore, with a trade flow share of nearly 14%. The remaining marginal trade flows exhibited a diversified pattern, radiating broadly to emerging steel capacity clusters in the Middle East, including Bahrain, Oman, and Saudi Arabia. (Chart-3: African Iron Ore Market Overview) Enterprise level, Kumba Iron Ore and Assmang , both based in South Africa, became Africa's largest and second-largest iron ore producers with annual production of 37 million mt and 17 million mt, respectively. Kumba's mines such as Sishen are globally renowned for producing high-grade fines (>62%) and premium lump with excellent physical and metallurgical properties (Premium Lump, Fe 65.2%). Under the current trend of blast furnace emission reduction, this type of lump ore that can be directly charged into furnaces and reduce sintering carbon emissions has been highly sought after by the market, commanding a significant premium. Assmang also possesses high-quality iron ore assets, jointly controlled by African Rainbow Minerals (ARM) and Assore at a 50:50 ratio. Its Assmang fines and Assmang lump (grade at 64-65%) are also high-quality direct furnace charge materials. However, for this enterprise, the biggest bottleneck lies not at the pit head but on the rails. Heavy reliance on Transnet's rail shipping capacity means that logistics bottlenecks frequently cap its shipment volumes. SNIM (Société Nationale Industrielle et Minière de Mauritanie) is Mauritania's state-owned mining company and Africa's third-largest iron ore producer after the two South African companies. Unlike mainstream Australian and Brazilian ore, SNIM's products occupy a unique niche in terms of physicochemical specifications and market segmentation. Its most widely traded product is TZFC fines, characterized by extremely low aluminum (Al2O3) and phosphorus (P) content. As an excellent blending raw material, major steel mills prefer to blend SNIM ore fines with high-aluminum Australian fines (such as certain Pilbara blend ores) to significantly dilute the impurity ratio in furnace charge and optimize blast furnace performance. (Chart-4: Top-Tier Enterprises) III. Transformation of the African Market: Major Producing Countries May Stagnate While Emerging Projects Become Key Growth Drivers So where will future growth come from? According to SMM observations, the African market is expected to undergo significant structural changes over the next five years. Multiple large-scale iron ore projects across African countries are already under construction and plan to commence production before 2030. Based on estimates, Africa's iron ore supply is expected to grow substantially from approximately 95 million mt currently to 260 million mt over the next five years, representing a cumulative increase of up to 85%. The market landscape will also shift from South Africa-dominated exports led by Western players to Guinea-dominated exports. (Chart-5: African Market Production Trend) The primary growth driver will come from Guinea in West Africa. The country's renowned Simandou iron ore mine, jointly developed by multiple enterprises, is currently the world's largest undeveloped high-grade open-pit hematite deposit. With resource reserves exceeding 5 billion mt and a designed capacity of 120 million mt, it is the project with the greatest strategic potential to reshape the existing iron ore market landscape. Since the first ore shipment in late November 2025, as of Q1 2026, Simandou's main export port, Morebaya Port, has cumulatively shipped nearly 1.6 million mt. Blocks 1 and 2, developed under the leadership of the Winning Consortium Simandou (WCS), have been successfully commissioned, with 2026 capacity expected to be achieved and shipments expected to reach full production of 60 million mt within the next 2–3 years. Blocks 3 and 4, which are expected to commence production in Q1 2026, are led by Simfer (a Rio Tinto & Baowu joint venture) and are expected to ship 5 million mt of ore in 2026, reaching full production of 60 million mt over 30 months. In other words, Guinea is expected to reach 120 million mt before 2030, vaulting to become the world's second-largest iron ore project, behind only Brazil's S11D project (with a post-expansion designed capacity of 200 million mt, expected to commence production in 2030). Other countries such as Liberia, Gabon, Sierra Leone, and Congo Republic all have iron ore projects under development, with a combined capacity of approximately 46 million mt planned to commence production by 2030. The largest among these is the Tokadeh Phase II project (Tokadeh Phase II) in Liberia, owned by ArcelorMittal (AML), which is expected to commence production in H2 2026 and reach full production of 20 million mt capacity by year-end, with iron ore concentrate expected to exceed Fe 66%. Given that AML's steelmaking capacity in Europe cannot absorb such a massive increase in the short term, the majority of Tokadeh 's products are expected to flow into the international market for trading, exerting downward pressure on iron ore concentrate prices. Currently, the largest exporting country, South Africa, is expected to largely maintain its production within the range of 63–67 million mt, with a risk of slight decline. The primary reason is that South Africa's iron ore transportation is highly dependent on the heavy-haul railway line (TFR) from Sishen to Saldanha Port. In recent years, Transnet Freight Rail (TFR), under South Africa's national transport company Transnet, has seen a significant decline in transport capacity due to numerous issues including locomotive and rolling stock shortages, frequent cable theft, and prolonged underinvestment in infrastructure, resulting in severely reduced transportation capacity for major bulk commodities such as iron ore and coal. South Africa's largest iron ore mine, Kumba, in its 2025 year-end financial report released in February 2026, indicated that its total finished product inventories reached as high as 7.5 million mt , increasing rather than decreasing compared to 6.9 million mt at the end of 2024. As railway transport capacity failed to match mine production capabilities, major South African iron ore producers were forced to accumulate large inventories at mine sites. To prevent inventory overflow, miners had to proactively lower production guidance. Although miners have been working to address transportation issues, the deep-rooted railway problems are difficult to resolve in the short term. Beyond 2030, there is also Mauritania's SNIM strategic growth blueprint. In the first phase (Horizon 1), the company plans to raise annual capacity to 45 million mt by 2031 through implementing lean production, equipment and technology upgrades, and joint development of new reserves. Of this, 20 million mt will be absorbed by SNIM's own wholly-owned capacity, while another 25 million mt will be achieved through attracting international capital to form joint ventures. Furthermore, SNIM has even set its sights on 2045 (Horizon 3), formulating a long-term goal of raising annual capacity to 80 million mt . In addition, there is the MIFOR project in the DRC. On March 26, 2026, the DRC signed a relevant memorandum of understanding with China, and the MIFOR project was listed as a flagship project with priority support. The mine is estimated to hold cumulative resources of 15 billion to 20 billion mt, with an average grade exceeding 60%. Its potential scale is considered to be approximately 2.5 times that of the Simandou project in Guinea. The first phase of the project is expected to cost $28.9 billion, involving the construction of a heavy-haul freight railway combined with Congo River shipping, ultimately connecting to the Banana deep-water port on the Atlantic coast. Initial annual production is expected to be 50 million mt, with a long-term goal of expanding to 300 million mt per year . All these projects are destined to make Africa an indispensable source of iron ore supply in the future. (Chart-6: Selected African Iron Ore Projects) IV. Global Steel Industry Chain Transformation: Will Africa, as a Hub of High-Grade Ore, Empower DRI Production? Notably, most of Africa's currently operating and planned iron ore projects have an average total iron grade (Fe) largely above 65% , with extremely low impurity content. This scarce high-grade ore is an ideal raw material for the direct reduced iron (DRI) process. As the DRI-EAF green steel route gains traction in Europe, the US, and China, future demand for iron ore with grades of 65% and above will surge exponentially. This will confer an exceptionally high "grade premium" on major iron ore projects including South Africa's Kumba, Guinea's Simandou, and other mines coming into production in the future. In the long run, the pricing benchmark for iron ore is inevitably shifting away from the traditional Platts 62% index, and African miners will gain bargaining leverage when renewing long-term agreements, thereby reshaping the global industry chain profit distribution landscape. In line with the global carbon neutrality trend, international investors, encouraged by local governments, are actively deploying high-value-added processing facilities, including DRI plants and high-grade pellet plants, aiming to fully leverage Africa's abundant high-grade iron ore resources and enormous energy potential for DRI production. Based on SMM's observations, approximately 200,000kt of DRI capacity is expected to emerge in Africa by 2030. The largest project among them is an 8.1 million mt DRI complex located in Libya, a joint venture between Turkish steel mill Tosyali and Libya's national steel company. (Chart-7: African DRI Projects) As China advances its "dual carbon" goals, the steelmaking industry is undergoing corresponding adjustments. China has set out a strategic blueprint for carbon peaking by 2030 and carbon neutrality by 2060. The traditional high-carbon-emission long-process steelmaking route dominated by blast furnace-converter operations is facing extremely stringent capacity replacement policies and environmental protection regulations. Meanwhile, the global trade system is also accelerating the imposition of carbon costs — for example, the implementation of the EU's Carbon Border Adjustment Mechanism (CBAM) — compelling the global steel supply chain to accelerate its transition from the source toward a low-carbon or even zero-carbon "green steel" era. Under this irreversible transformation trend, the short-process route combining DRI with electric furnace (EAF) has become the most commercially feasible decarbonization pathway. To meet the surging global demand for green steel in the future, market forecasts indicate that by the 2030s, global DRI designed capacity will need to increase by hundreds of millions of metric tons. This dramatic expansion in production scale will profoundly reshape the global steel supply landscape. The share of traditional pig iron production will gradually decline, while low-carbon DRI supply will directly determine the competitiveness of major economies in the global green steel market. In particular, the "hydrogen metallurgy" technology, which uses green hydrogen to replace natural gas and coal for iron ore reduction, is widely recognized by the industry as the core to achieving ultimate zero-carbon steelmaking. (Chart-8: Reshaping of the Steel Industry Chain Under Green Transformation) Represented by world-class high-quality iron ore projects such as Simandou in Guinea, the gradual commissioning of these super mines is expected to inject over 100 million mt of high-grade iron ore supply into the global market annually, significantly alleviating the global shortage of DRI-grade ore. More critically, North Africa and West Africa possess solar and wind energy potential that is second to none globally, enabling large-scale green hydrogen production at extremely low costs locally. This perfect combination of "high-grade ore + affordable green hydrogen" has led multinational capital and steel giants to increasingly favor establishing DRI production lines directly on African soil, reducing iron ore locally into low-carbon Hot Briquetted Iron (HBI) that is convenient for transport, before shipping it to electric furnaces in Asia and Europe for smelting. As a result, Africa will formally transition from the old era to become an indispensable part of the green iron production chain.
