The investor relations activity record of Yunnan Copper for May 26–27, 2026 shows: 1 What is the company's planned copper concentrate production from captive mines this year, and what is the approximate cost level of the mining enterprises? According to the company's 2026 financial budget and production plan, full-year self-produced copper concentrates are expected to contain 69,800 mt of copper metal content. The company's current mining enterprises mainly include Diqing Nonferrous, Liangshan Mining, Yuxi Mining, and Diqing Mining. Due to differences in resource endowment and the life cycle stage of each mine, cost levels vary, with Diqing Nonferrous, Liangshan Mining, and Yuxi Mining having relatively lower costs. Meanwhile, the company strives to maintain overall cost stability through measures such as lean operations and increasing mining volumes. 2 What is the progress of the Hongnipo copper mine construction project of Liangshan Mining? The Hongnipo copper mine is currently under construction, with cumulative verified resource reserves of 16.06 million mt of ore, an average copper grade of 1.42%, and copper metal content of 592,900 mt. The project is progressing in an orderly manner as planned and is expected to be completed and ready for commissioning in 2026. 3 Will the mine resources under the company's major shareholder be injected into the publicly listed firm? Asset injection involves complex systematic work that requires comprehensive consideration of development strategy, asset conditions, regulatory requirements, and shareholder interests. The company will continue to focus on and strive to enhance the quality of the publicly listed firm, and if there are any new relevant arrangements, it will strictly follow prescribed decision-making and disclosure procedures. 4 Has the company set a target for resource self-sufficiency rate? The company regards improving resource self-sufficiency rate as an important long-term strategic task, relying primarily on three paths: commissioning of projects under construction, tapping potential of existing mines, and external resource acquisitions. Regarding projects under construction, the company successfully completed the acquisition of 40% equity in Liangshan Mining in December 2025, and the Hongnipo project is expected to be completed and ready for commissioning in 2026. Regarding tapping potential of existing mines, the company leverages its major mines to continuously intensify deep and peripheral exploration efforts, steadily advancing resource succession and reserve additions. Regarding external resource acquisitions, while managing existing mines and smelters well, the company actively monitors quality mineral resource projects and prudently conducts field trips and evaluations based on strategic positioning and market demand. 5 What proportion can the company's copper smelting TC long-term contracts approximately reach? The company follows the principles of marketization and maximization of comprehensive benefits in externally purchasing raw materials. As one of the larger copper concentrate purchasers in China, the company has long maintained good, stable, long-term cooperative relationships with major suppliers, and actively negotiates with copper concentrate suppliers to stabilize long-term contract supply and ensure orderly production. 6 What were the company's sulphuric acid selling price and production in Q1 2026? According to the company's 2026 production plan, planned annual sulphuric acid production is 5.76 million mt. In Q1 2026, sulphuric acid production progressed in an orderly manner as planned. Price side, as a by-product of copper smelting, sulphuric acid selling prices are influenced by multiple factors including regional market supply and demand, transportation conditions, and industry prosperity. Since the beginning of this year, driven by robust downstream demand and tight supply in some producing areas, sulphuric acid selling prices have stayed high. The company seized market opportunities, reasonably arranged production and sales, and made positive contributions to operating performance. Meanwhile, the company will continue to monitor price changes and dynamically optimize production and sales pace. 7 Does the company have further cost reduction plans? The company's mining and smelting enterprises continuously pursue lean cost reduction to build low-cost competitive advantages. For example, the company is comprehensively advancing the "Three-Year Cost Reduction 3.0" initiative, continuously promoting cost reduction and efficiency improvement, and lowering unit production costs through technological upgrades, process optimization, and improved management efficiency. 8 What major capital expenditures are expected in the future? The company's future major capital expenditures will primarily focus on the following strategic directions: first, resource acquisition—continuously strengthening exploration and acquisition of quality copper mineral resources in and outside China to enhance resource security capabilities; second, intelligent manufacturing—advancing automation, digitalization, and intelligent upgrades of mines and smelting plants to improve production efficiency and safety levels; third, green and low-carbon development—increasing investment in environmental protection, energy conservation, and other areas to promote sustainable development. Performance side: Yunnan Copper's Q1 2026 report disclosed on April 24 showed that the company achieved total operating revenue of 52.959 billion yuan, up 49.62% YoY; net profit attributable to the parent was 675 million yuan, up 7.93% YoY. Regarding the reasons for the increase in operating revenue, Yunnan Copper stated that it was mainly due to higher product prices compared to the same period last year and increased sales volumes compared to the same period last year. Yunnan Copper's 2025 annual report showed that in 2025, the company firmly established market entity awareness, strengthened its lean operations system, and solidly carried out production organization, cost control, indicator optimization, marketing value creation, and other work, with main product production reaching record highs and key technical and economic indicators continuously optimized. Full-year production included copper cathode of 1.6411 million mt, gold of 26.04 mt, silver of 735.38 mt, and sulphuric acid of 6.189 million mt, with copper cathode, gold, and silver production all reaching record highs. Full-year operating revenue reached 79.542 billion yuan and net profit attributable to the parent was 1.301 billion yuan, with operating efficiency steadily improving. Cost and technical indicators were continuously optimized, with mine concentrate copper content and smelting copper cathode unit full cost outperforming annual cost reduction targets. Key technical indicators for smelting and mining remained stable with improvement. In 2025, the copper smelting total recovery rate exceeded the target by 0.07 percentage points, and slag flotation tailings copper content was optimized by 0.01 percentage points versus the target, both reaching industry-leading levels. Yunnan Copper announced that in 2025, the company's concentrate copper content production, on a consolidated statement basis, was 69,400 mt, up 26.64% YoY from 2024, mainly because the company issued shares to acquire 40% equity in Liangshan Mining held by Yunnan Copper Group during 2025, and Liangshan Mining was included in the consolidated statements as of December 31, 2025, with its full-year production included in the statistics. Regarding the company's main businesses, Yunnan Copper introduced in its 2025 annual report: The company's main businesses cover copper exploration, mining and beneficiation, smelting, extraction of precious metals and rare scattered metals, sulphur chemicals, and trading. It is an important copper, gold, silver, and sulphur chemical production site in China. The company has established a relatively complete industry chain in copper and related nonferrous metals and is a copper enterprise with deep industry heritage. Main products include copper cathode, gold, silver, industrial sulphuric acid, and rare and scattered metal products such as molybdenum, platinum, palladium, selenium, and tellurium. The company's main products are all produced according to international standardization organization standards, operating effectively under the international ISO9001 quality management system to ensure strict quality control. The company's main product, copper cathode, is widely used in electrical, light industry, machinery manufacturing, construction, national defense, and other fields; gold and silver are used in finance, jewelry, electronic materials, etc.; industrial sulphuric acid is used as raw material for chemical products and in other sectors of the national economy. The company's "Tiefeng" brand copper cathode is registered on the Shanghai Futures Exchange and the London Metal Exchange; "Tiefeng" brand gold is registered on the Shanghai Gold Exchange (SGE) and the Shanghai Futures Exchange; "Tiefeng" brand silver is registered on the Shanghai Gold Exchange (SGE), the Shanghai Futures Exchange, and the London Bullion Market Association. Regarding the company's future development outlook, Yunnan Copper introduced in its 2025 annual report: Yunnan Copper adheres to the guidance of Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era, fully implements the spirit of the 20th National Congress of the Communist Party of China and its successive plenary sessions, and upholds and strengthens the Party's overall leadership. The company actively serves major national strategies, adheres to promoting high-quality development as the theme, fully, accurately, and comprehensively implements the new development philosophy, continuously enhances core functions and improves core competitiveness, and better plays its role in scientific and technological innovation, industrial control, and security support in building a modern industrial system and constructing a new development pattern. The company emphasizes "two guarantees" (important mineral resource guarantee and important metal material guarantee), "two innovations" (scientific and technological innovation and management innovation), "two constructions" (strengthening Party building, especially cadre team building), and "three unwavering commitments" (unwavering in accelerating structural adjustment, unwavering in deepening enterprise reform, and unwavering in international operations and increasing "going global" efforts). The company focuses on "digital-intelligent transformation, expanding resources, refining mines, optimizing smelting, solidifying recycled (copper), and detailing rare scattered (metals)," accelerating the construction of a world-class excellent copper company, and continuously opening new prospects for Yunnan Copper's high-quality development. Guosen Securities' research report commenting on Yunnan Copper on April 11 showed: Quality asset consolidation. Production side, the company's copper ore production was close to 70,000 mt, with major mines maintaining stable production. Copper smelting side, after Southwest Copper reached full production, the company's 2025 copper cathode production was 1.64 million mt, up 440,000 mt or 36% YoY. During the reporting period, the company purchased 40% equity in Liangshan Mining through share issuance to its major shareholder, achieving consolidation. Liangshan Mining is a quality asset, with its mines featuring open-pit mining, abundant reserves, higher grade than the publicly listed firm's existing copper mines, and lower costs than the publicly listed firm's existing copper mines. In H2 2025, profitability of major subsidiaries generally declined. Although copper, gold, and silver prices rose significantly in H2 2025, the company's mining operations saw profit decline QoQ. Smelting operations also declined significantly in H2 2025, which was related to the sharp drop in copper concentrate TCs. As sulphuric acid prices are expected to stay high, the company's smelting business profitability is expected to improve. Gross profit by product side, the company produces over 6 million mt of sulphuric acid annually. Benefiting from sulphuric acid price increases, sulphuric acid business gross profit in 2025 was 2.03 billion yuan, up 1.5 billion yuan YoY, representing a performance highlight. Since early 2026, sulphuric acid prices have continued to rise, and this is expected to further boost earnings. Leveraging the copper industry's high-prosperity cycle in recent years, the company's asset quality has improved, and during the reporting period it achieved consolidation of Liangshan Mining, a quality asset. As the sole copper publicly listed platform under Chalco Group, injection of other quality assets from the major shareholder is anticipated. Although the copper smelting business is under pressure in the short term, the government has issued policies to strictly control new copper smelting capacity, and the company benefits from global copper smelting capacity rationalization, with a favorable long-term industry landscape. Maintain "Outperform" rating.

I. Market Status: Negative TCs Enter Triple Digits, Structural Tightening in Copper Concentrate Supply-Demand As global smelter capacity continues to climb, China, as the world's largest copper smelting country, faces a continuously declining self-sufficiency rate in copper concentrates and rising external dependency. Compounded by geopolitical crises, production cuts by ex-China miners, declining mine grades, and frequent production accidents, the copper industry has undergone a dramatic shift from "tight balance" to "structural deficit." Currently, the global copper concentrate market has fallen into a state of persistently tight supply. On May 15, the SMM Imported Copper Concentrate Index (weekly) reported -$102.84/dmt, breaking through the -$100/dmt threshold for the first time in history, setting a record negative depth. The payable indicator for 20%-grade domestic trade ore was 97.5%-98.5%, up 0.5 percentage points MoM. Supply-side factors driving TCs persistently lower continue to accumulate. 1) Full production resumptions at Freeport's Grasberg mine have fallen short of expectations. According to Freeport's Q1 earnings call, the company plans to achieve full production resumptions by the end of 2027; 2) The Peruvian government signed Emergency Decree No. 003-2026 on May 11, triggering widespread market concerns over the country's energy supply and copper mine output; 3) Geopolitical disruptions—the continued blockade of the Strait of Hormuz has driven sulfur prices persistently higher, pushing smelting acid prices to rise continuously. With smelting profits climbing, smelters' purchase willingness has increased, driving copper concentrate TCs persistently lower. Customs data showed that China's copper ore and concentrate imports in April 2026 were 2.352 million mt in physical content, down 19.57% YoY; cumulative imports from January to April were 9.915 million mt in physical content, down 0.8% compared to the same period last year. Since December 2020, China's copper concentrate cumulative imports had maintained positive YoY growth; this marks the first decline in over five years. II. Smelter Operating Rates Stay High Contrary to the intuition of "industry-wide losses" implied by deeply negative TCs, operating rates at China's copper smelters have not experienced a cliff-like decline. From a pure smelting perspective, operating willingness and actual profitability across different types of enterprises show significant divergence. Under the extreme environment of deeply negative TCs, the core reason China's copper smelters can maintain relatively resilient operations is that by-product revenues are becoming the key variable determining break-even. Meanwhile, China's copper cathode production declined MoM due to the maintenance peak. SMM data showed that China's copper cathode production in April fell 2.26% MoM. Cumulative copper cathode production from January to April 2026 reached 4.7067 million mt. However, according to SMM, some smelters postponed their maintenance plans or completed crude smelting maintenance ahead of schedule to capture revenue from the by-product sulphuric acid. III. Breakdown of Smelter Profit Sources (i) Sulphuric Acid: The Strongest Profit Contributor at the Current Stage Sulphuric acid is currently the most important by-product profit source for smelters. In pyrometallurgy-based copper cathode production, approximately 3-4 mt of sulphuric acid is produced as a by-product for every 1 mt of copper cathode. As of May 15, the SMM China Copper Smelting Acid Index stood at 1,665 yuan/mt, up 83.7% from the beginning of the year. Sulphuric acid prices currently stay high, meaning sulphuric acid revenue can offset a considerable portion of the revenue loss caused by negative TCs. However, this "sulphuric acid moat" is facing policy challenges. China suspended exports of ordinary industrial sulphuric acid and smelting by-product sulphuric acid starting in May for a period of 8 months. The export ban is not intended to suppress domestic sulphuric acid prices, but rather to prioritize domestic supply for agricultural phosphate fertiliser production and strategic industries such as new energy. Demand side, overall sulphuric acid demand remains tight. Although downstream sectors including phosphate fertiliser, titanium dioxide, and new energy materials saw declining operating rates due to high-priced raw materials, just-in-time procurement still exists. Meanwhile, the supply side is also constrained by concentrated smelter maintenance and high sulphur-based acid production costs, with industry-wide capacity utilization rates at low levels. Cost side, firm sulphur prices provide bottom support for sulphuric acid; supply side, concentrated maintenance limits downside room; demand side, although weak, has not yet formed a substantial enough impact to break down high prices. This means sulphuric acid continues to serve as a profit pillar for smelters. (ii) Precious Metal Recovery: "Incremental Game" Under High Copper Prices In addition, copper concentrates typically contain associated precious metals such as gold and silver, which can be recovered through anode slime processing during smelting. Copper prices are currently at historically high levels, and gold prices also fluctuate at highs, greatly enhancing the economics of precious metal recovery. According to SMM market sources, when gold and silver prices are at high levels, raw materials with impurities rich in gold and silver are assigned extremely high added value. The profit contribution of precious metal recovery to smelters is reflected in: smelters can achieve recovery utilization rates exceeding the gold and silver payable indicators through refined processing, profiting from spot smelting revenue. This portion of revenue is often a significant component of smelters' comprehensive profit structure. However, as gold and silver prices continue to rise, suppliers in the copper concentrates spot trade are simultaneously raising gold and silver payable indicators. The continuously rising precious metal payable indicators and payable benchmark pose an increasingly severe challenge to smelter profitability. IV. Future Trends: Coexistence of Industry Landscape Evolution and Technology Upgrade Requirements However, industry chain profits are irreversibly shifting toward the upstream ore side. Under the medium and long-term landscape of persistently tightening copper concentrates supply and demand, the scarcity value of the resource side is being reassessed by the market. As the copper concentrates supply-demand gap persists over the medium and long-term horizon, and smelters' bargaining power will remain under pressure over the long term. The market is widely concerned about whether TC can quickly pull back in tandem once the continuously rising sulphuric acid prices reach a turning point. Facing the long-term trend of profit squeeze at the mine end and losses in the smelting segment, the future landscape of the copper smelting industry will evolve in the following directions: Direction 1: Integrated consolidation extending upstream. Enterprises with upstream mine assets will have a significant advantage in profitability. Direction 2: Technological upgrades to achieve differentiated competition. Against the backdrop of narrowing profit margins from non-payable metals, the technological barriers of smelters will become increasingly important. Those who can more efficiently extract valuable metals from low-grade ore or complex ore will seize the initiative in the industry reshuffle. Under the extreme environment of persistently negative TCs, sulphuric acid by-product revenue and precious metal recovery are the core profit pillars currently sustaining smelter operations. The supply-demand pattern dictates that the pricing power and profit margins at the mine end will continue to outperform those at the smelting end. The copper smelting industry is transitioning from the traditional model of "earning TCs" to a new competitive landscape of "resource control + technological barriers + integrated operations."

The 2026 SMM Hong Kong Metals Forum , organized by Shanghai Metals Market (SMM) and sponsored by China Securities International as platinum sponsor, wrapped up successfully at Novotel Hong Kong Century on May 6. With over 300 registrations and 200 on-site attendees, the forum focused on the theme "New Metals Cycle: Prices, Power & Global Wrestling". The event featured keynote speeches by industry experts and SMM analysts, covering base metals, new energy materials, and strategic revaluation of minor and precious metals. Two high-level panel sessions were held, exploring hot topics such as geopolitics, supply-demand fluctuations, CBAM impacts, and market opportunities. It also served as an efficient platform for networking and cooperation across entire industry chains. SMM Opening Address SMM Chairman Adam Fan SMM Chairman Adam Fan stated in the opening address that it was a great honor to gather with elites from all sectors of the industry at this forum. The world is currently at a critical development period, and the exchange of industry ideas is not only an industry necessity but also an inevitable requirement for global development. Adam reviewed the century-long legacy of the London Metal Exchange, which has weathered nearly 150 years of global changes and industry evolution, fully demonstrating that although market structures may change, the fundamental need for risk management and reliable price discovery remains constant. At the same time, Adam candidly acknowledged that global markets are currently mired in a pattern of deep fluctuations. Geopolitical conflicts, supply chain fragmentation, and the compounding crises of energy and food, overlaid with de-globalization and rising trade protectionism, have intensified market uncertainty and inflationary pressures, posing severe challenges to global economic growth and industrial cooperation. Against this backdrop, SMM has steadfastly upheld its mission, refusing to be a bystander to the trend of industry fragmentation, and is committed to serving as a bridge for global industrial connectivity amid a landscape of division. SMM is dedicated to promoting dialogue and exchange, breaking down industry and regional barriers, and bringing together regulators, traders, and producers from around the world to discuss industry development. SMM upholds the principle of information transparency, continuously providing accurate, real-time market data to help the industry see through market fog and clarify market distortions. SMM deepens pragmatic cooperation by building a neutral and professional platform for exchange and matchmaking, driving all parties to pursue collaborative development based on shared interests and transcending political differences. Adam emphasized that information sharing and open collaboration would be leveraged to mitigate market risks and strengthen overall industry resilience, and called on the industry to seize the opportunity of this forum to jointly explore solutions, transforming current challenges into momentum for driving integrated and robust development of the global metals industry. Speech by Platinum Sponsor Wang Guangxue, Member of the Executive Committee of China Securities Co., Ltd. and Chairman of China Securities Futures Co., Ltd. Wang stated that as a vital bridge connecting the capital market and the real economy, China Securities has always been committed to serving the high-quality development of the metals industry. Leveraging the comprehensive financial strengths of CITIC Group, the company has built a full-chain integrated service system covering securities, futures, investment, and research.

The company aims to tailor integrated risk management and asset allocation solutions at home and abroad for enterprises across the metals industry chain, precisely helping enterprises hedge against price fluctuation risks, and enabling them to operate steadily and advance with high quality in complex market environments. Structural Shifts: Rethinking Commodity Benchmarks in an Era of Persistent Inflation and Rivalry Speaker: Tian Yaxiong, Co-Head of R&D Department, China Securities Futures Tian shared professional research findings and cutting-edge market insights on hot topics including the market outlook for global metals and the deep impact of geopolitics on commodity trends. SMM Industry Analysis: Market Outlook and Pre-seminar Sharing for Base Metals and New Energy Materials (Copper, Aluminum, Nickel, Cobalt, Lithium, and Tin) & How SMM Empowers Your Commodity Trading & Analysis Speakers: Dr. Yanchen Wang, Managing Director of SMM Global UK Ltd.; Thomas Feng, Head of Industry Analysis at SMM Dr. Wang first analyzed the macroeconomic landscape. At the beginning of this year, the manufacturing PMIs of major economies performed quite well, actually exceeding 50%. Without the conflict, demand this year would have been quite strong. However, at the end of February, the US-Iran conflict broke out, and the International Monetary Fund subsequently revised down its global economic growth expectations. He pointed out that China's exports remain one of the three pillars that are still functioning well to date. Regarding automobile consumption, he noted that for the EV market, the positive factor for the auto industry also lies in exports. In Q1 this year, export performance was indeed very strong. If you look at EV exports alone, they actually grew nearly 160% YoY. Driven mainly by growth in global markets, he remains optimistic about the auto industry this year. In Europe, gasoline and diesel prices have risen significantly due to the US-Iran conflict, and EV demand is expected to benefit from this factor. He believes the power sector continues to maintain strong growth. Based on power grid and power generation investment data from the first two months, combined with State Grid Corporation of China's earlier announcement that fixed asset investment during the "15th Five-Year Plan" period is expected to reach 4 trillion yuan, this indicates that electricity demand will drive strong growth. State Grid Corporation of China will build more ultra-high voltage transmission projects, which will undoubtedly support aluminum demand and also copper demand. Aluminum: Wang noted that base metal prices experienced wild swings since the beginning of this year. He also discussed that China's aluminum smelters continued to raise operating rates due to favorable profitability; aluminum demand pulled back in Q1, and high prices drove inventory higher; approximately 950,000 mt of new aluminum smelting capacity in Indonesia may come online in 2026, with some investors watching Angola; and aluminum semis and wheel hub exports maintained growth in Q1. Copper: After copper prices experienced a pullback and adjustment in March, downstream procurement demand in China was rapidly released, providing strong support for copper prices to rebound. Copper prices rose sharply, with the market downplaying geopolitical risks. China's copper cathode demand was robust, and inventory continued to decline. China's copper scrap market was not truly facing a spot shortage issue. The outlook for copper cathode demand is positive. China remains dependent on copper concentrate imports. Spot copper concentrate TCs showed no signs of bottoming out. By-product revenue sustained smelter profits. He also analyzed the DRC sulphuric acid market conditions, the expected slowdown in global refined production growth, and how a refined market supply deficit should support higher copper prices. He also mentioned that the AI industry maintained strong development momentum, bringing new growth momentum to copper demand. Tin: He elaborated from the following perspectives: Myanmar tin production — slow recovery, upward trajectory, 2025-2027E; Indonesia tin ore RKAB quotas — expected to ease slightly in 2026; DRC — major mine production remained stable, but the M23 movement added uncertainty; global tin prices — supply determines the floor, macro factors drive fluctuations; the global tin market is expected to maintain a tight balance, with new mining capacity expected to be concentrated for release in 2028. Thomas Feng shared insights on nickel, cobalt, and lithium: emerging from the trough and entering a new cycle. ►New energy demand landscape: from EV popularization to energy storage deployment. First, he reviewed and provided an outlook on the global NEV market: NEV demand no longer maintains a one-sided high-growth trajectory, but instead exhibits characteristics of regional differentiation, structural divergence, and intensifying cyclical volatility; development paces in China, Europe, and the US have shown notable differences; performance trends of BEVs, PHEVs, and commercial vehicles have diverged; and the impact of inventory and price cycles on industry operations is increasing significantly. Second, in his review and outlook of the global energy storage market, he noted that the global energy storage market will remain concentrated in three key regions: China, the US, and Europe. Driven by 2030 climate goals, emerging markets such as the Middle East, Australia, and Southeast Asia are showing strong growth in demand for large-scale energy storage. Benefiting from cost advantages and improved safety performance, LFP battery market share is expected to continue climbing. ►Lithium: Reshaping the Supply-Demand Pattern in a New Cycle Global lithium carbonate market: shifting from overall surplus to structural tightness, with prices in a post-trough reassessment and recovery phase. Lithium hydroxide supply and demand maintained a tight balance: production on the supply side was driven by demand, the market share of ternary power batteries was squeezed, and room for growth was limited. The concentration of lithium resource supply declined, with marginal growth rates slowing down simultaneously. Significant demand growth drove the continued expansion of resource projects. ►Nickel: Navigating Policy Changes and Narrowing Oversupply Indonesia's nickel ore HPM adjustment: aimed at enhancing the economic value of non-nickel resources. The discussion covered scenario analysis of nickel ore prices following the implementation of the new policy, and the impact analysis of nickel ore benchmark price adjustments on MHP full costs. Indonesia's nickel ore RKAB quota: a tight balance is expected to set the tone for 2026. Global primary nickel is expected to remain in persistent oversupply. Regarding the logic behind refined nickel price trends, it was noted that policy and macro factors jointly amplified price fluctuations, while cost support elevated the long-term price floor. ►Cobalt: Shifting from Surplus to Shortage after the DRC Export Ban——Long-Term Uncertainty Remains Following the DRC policy announcement, cobalt product prices in China rose rapidly. However, high prices suppressed downstream demand, putting prices under pressure. Starting from H2 2025, the Chinese market continued destocking. Amid raw material shortages, enterprises began using MHP and recycled materials as production substitutes. MHP and recycling are expected to continue growing rapidly, effectively bridging the cobalt hydroxide gap. Cost pressure transmitted in both directions: LCO doping/ternary substitution restarted, and consumer cobalt demand is expected to decline by 10%. As persistently high cobalt prices suppress demand, if China secures 90% of the DRC quota, supplemented by MHP and recycling supply, inventory buildup could occur as early as 2026. Panel Discussion: Global Metals Market Outlook——Geopolitics Disruption, Macro Cycles and the Return of Commodity Volatility •Copper and Aluminum Price Rise, 2024-2026 •Precious Metals Storm: Silver Swung Wildly, Gold Hit Record Highs — Interest Rate Cycles, Safe-Haven Demand, and Industrial Logic •Precious Metals and Industrial Metals: Are Commodities Entering a New Cycle •Focus on Critical Minerals: Emerging Region Supply Rise and Policy Shifts, Green Transition Co-Shaping a New Narrative •Chinese Market: The 15th Five-Year Plan Moderator: Yanchen Wang, Managing Director, SMM Global UK Ltd. Panelists: Yahong Tian, Co-Head of R&D, CITIC Futures Henry Van, Head of Industrial Metals Analysis, Trafigura Sharon Ding, Head of China Basic Materials, UBS Justin William Hughes, Commodity Derivatives Distribution, Optiver Xie Shaobo, Head of China, Appian Mining Fund & independent non-executive Director, Zijin Gold International Panelists noted aluminum has great upside—its 10% price rise lags its 4%-5% supply contraction (vs. oil’s 60% price surge on 10% supply drop), with valuation recovery incomplete. They were more optimistic about copper demand, driven by real downstream demand rather than speculation; aluminum semis’ upside is underappreciated due to high oil prices. Long-term, copper and gold are key for mining investment, with scarce high-quality copper mines and solid gold fundamentals. They also discussed US tariffs, China’s metal demand resilience and overseas mining investment. Overseas mining success hinges on resource-to-reserve certainty; West Africa, Latin America, DRC and Zambia are new hotspots, while Australian/Canadian listed miners are undervalued. Enterprises must plan prudently based on risk tolerance. Geopolitical conflicts (e.g., Iran) may trigger energy crises, but current inflation control and China’s high metal consumption share weaken demand impact. Long-term, energy crises will boost electrification, expanding copper/aluminum demand. Investment depends on risk appetite and fundamental grasp. SMM Industry Analysis: Strategic Re-valuation of Minor Precious and Minor Metals in 2026 — The Case of Silver and Tungsten Silver: Market Supply-Demand Balance and Macroeconomic Volatility: Evolution and Shift in Industrial Demand, Particularly Driven by the PV Sector Tungsten: Strategic Status Upgrade - Supply Constraints and High-End Demand Driving the 2026 Price Rally Speaker: Juno Zhu, Senior Analyst of Minor and Precious Metals, SMM Juno shared insights on the strategic revaluation of tungsten and silver. Tungsten: Tungsten prices have surged over 500% since 2025; China holds over 50% of global tungsten reserves, contributes nearly 80% of global production, and possesses a complete industrial value chain; China's tungsten supply constraints in 2025: H1 mining quotas declined 6.45% YoY; global new project stagnation: limited capacity expansion in 2026, with ex-China mine development cycles of 3–5 years; domestic tungsten downstream applications: significant growth in cutting tools and PV tungsten wire in 2025; European market: persistent raw material shortages, with Rotterdam tungsten prices surging since February 2025; China's tungsten product exports: transitioning from primary products to deep-processed products; SMM analysis: the tungsten market supply-demand gap is expected to persist but narrow in 2026; prices are expected to consolidate at highs after overheating cools. Silver: Silver price fluctuations in 2026: an unexpected surge from Q4 2025 to Q1 2026, where frenzied investment demand and capital liquidity completely overshadowed the impact of the industrial off-season. Shift in trade dynamics in Q1 2026: SGE-LBMA premiums reversal and a surge in imports. Demand spike in Q1 2026: the PV industry started with a recovery, and an investment boom generated a phased demand peak. PV market outlook: policy shifts in 2026 are expected to curb demand growth, with overall silver consumption remaining stable. Silver demand outlook for 2026: industrial fundamentals provide support, while investment surges serve as a tactical highlight. Silver supply outlook for 2026: mild annual growth and an expanding secondary supply share are expected to drive a tight balance in the market. Market outlook: short-term trends are expected to revert to industrial fundamentals, while the medium and long-term trajectory is expected to fluctuate at highs driven by safe-haven demand. Panel Discussion: Metals in a Fragmented World: Trading Opportunities in the Age of Instability (Physical Trading and Hedging) •Shifting Liquidity Landscape across LME, CME, and SHFE •Shipping Risks and Sanctioned Metals: Implications for LME Inventory Structure •How European CBAM is Reshaping Global Metals Trade Flows •Is the Metals Market Entering an "Era of Geopolitical Risk Premiums" •Internationalization of SHFE & GFEX: Opportunities and Challenges for Global Investors Moderator: Jean Tang, Commercial Director, SMM Panelist: Anant Jatia, Founder and Chief Investment Officer, Greenland Investment Management Bella Yu, General Manager of Marketing Department, Liyang Unilink E-commerce Co., Ltd. David Wilson, Director of Commodity Strategy, BNP Paribas Duncan Hobbs, Research Director, Concord Resources Nicholas Snowdon, Head of Metals and Mining Research, Mercuria Energy Trading SA Sabrina Qian, Director of Geared broking desk, IFCHOR GALBRAITHS Anant Jatia stated: CBAM represents a major policy shift in Europe's metals sector. It is not merely about raising trade costs, but will profoundly reshape global metal trade flows and pricing logic. CBAM officially took effect in January this year, initially covering categories such as steel and aluminum semis, with its core mechanism incorporating carbon emission intensity costs into Europe's metal pricing system. High-carbon-emission producers will need to bear additional carbon allowance costs, significantly weakening their export competitiveness to Europe, while green capacity powered by clean energy will gain a clear advantage in the European market and capture greater market share. Following the policy's implementation, the landed cost of metals in the European market will rise, sustaining a long-term regional premium similar to the aluminum premium structure in the US market. Compared with the market differentiation among LME-registered brands following CBAM's implementation, what deserves more attention are the entirely new market opportunities it creates. By sourcing low-carbon, high-quality materials, market participants can potentially capture green premiums, while the mechanism will also transform metal trading models and the global trade flow landscape. The panelists also discussed the changing liquidity landscape across LME, CME, and SHFE. They noted that liquidity in the commodity market is becoming increasingly fragmented, with copper and other products now tradable across multiple global futures exchanges. Price discovery is no longer concentrated in a single market, and the traditional pattern of one market leading gains and others following has reversed, with multi-exchange rotation driving price movements becoming the norm. Factors such as geopolitical policies and tariff adjustments have given rise to regional pricing divergence, with price movements in some markets increasingly driven by capital flows and sentiment. Policy and geopolitical events have also significantly affected the spread between futures and spot prices of metals, creating opportunities for cross-market arbitrage. Meanwhile, policies related to critical minerals supply security, regional supply shocks, and geopolitical disruptions have widened the dislocation between regional fundamentals and price signals. The metals market has entered a window of structural arbitrage opportunities, and this trend is expected to persist. Cross-market arbitrage continues to provide liquidity support to exchanges, a phenomenon broadly observed across both industrial and precious metals. In addition, the panelists engaged in in-depth discussions on the differences between exchange liquidity and industrial liquidity, as well as factors influencing metal price trends, including fundamentals, geopolitical developments, energy costs, and commodity transportation costs.

[SMM Analysis] Copper prices have surged recently. On the surface, the current hot topics in the copper market are focused on the following areas: the widening LME-COMEX price spread, copper concentrate TCs hitting new lows again, the energy crisis in Peru, the repeated fluctuations in the pace of Grasberg's production resumptions, and the substitution effect between copper cathode and copper scrap in China. However, from a deeper perspective, all these events can be understood under a single theme: the growing global emphasis on copper resource security, with the market repricing the entire industry chain.

[SMM Analysis] Sulphuric Acid: A Key Variable Reshaping Copper Pricing Logic

According to data from the online query platform of the General Administration of Customs, China's imports of copper ore and concentrates in March 2026 totaled 2,629,996.23 mt, up 13.84% MoM and 9.99% YoY. Shipments from major supplying countries such as Chile, Peru, and Mongolia all increased to varying degrees. However, spot copper concentrate TCs in China remained at low levels, and the tight ore supply situation continued. Below is the supply breakdown from major source countries for China's copper ore imports since March 2020: Data source: General Administration of Customs (Wenhua Composite)

March production was broadly in line with expectations, increasing by 63,700 mt from February on a MoM basis to a record high.

Since the beginning of this year, the spot treatment charge market for copper concentrates has shown an unprecedented and severe downward trend. The SMM Copper Concentrate Spot Index has fallen from -45 USD/dmt at the start of the year to near -70 USD/dmt, with the speed and magnitude of the decline being historically rare. A negative treatment charge means that when smelters purchase copper concentrates, they not only fail to receive traditional processing income from miners but instead must pay the sellers. Based on the current TC of -70 USD/dmt, the actual cost smelters pay sellers in the copper smelting process is equivalent to a TC of 70 USD, or further converted to a TC+RC of approximately 112 USD. This extreme price signal has quickly drawn high market attention to smelter profitability and even sparked concerns about the sustainability of domestic copper smelting production. Despite treatment charges falling to historic lows, copper cathode production by Chinese smelters remains at high levels, currently around 1.2 million tons per month. This phenomenon of "producing more while losing more" appears, on the surface, to contradict market logic, but actually reflects smelters' passive choices and structural supporting factors in the current complex environment. Historically, extreme treatment charge scenarios are not unprecedented. In past industry downturns, smelters often relied on one or several factors—exchange rate fluctuations, rising sulfuric acid prices, or treatment charges themselves—to barely maintain cash flow balance. In the current cycle, the sharp rise in sulfuric acid prices has become a key variable supporting smelter survival. Currently, the ex-factory prices of smelter acid sold by domestic copper smelters generally range from 800 to 1,600 yuan per ton. The latest SMM Copper Smelting Acid Index stands at 1,235.5 yuan/ton. As a crucial byproduct of copper smelting, sulfuric acid price fluctuations significantly impact smelters' comprehensive earnings. Typically, smelters produce approximately one ton of sulfuric acid for every dry metric ton of copper concentrate processed. Based on the current sulfuric acid price of 1,235.5 yuan/ton, after deducting value-added tax (at a 13% rate) and converting to US dollars (using an exchange rate of 6.9), each ton of sulfuric acid can contribute about 158 USD in revenue for the smelter, equivalent to an additional 158 USD per dry metric ton of copper concentrate. If further converted to the TC+RC metric, this amounts to about 99 USD. Thus, the rise in sulfuric acid prices has significantly offset the loss pressure from negative copper concentrate treatment charges, with some more efficient smelters even achieving marginal profitability. It is precisely this "stabilizer" role of sulfuric acid that allows smelters to maintain high operating rates under extreme treatment charge conditions. However, the support of sulfuric acid for smelting profits is not unlimited, as its price trend is itself influenced by more complex international geopolitical factors. The recent sharp escalation of the Middle East situation has brought significant uncertainty to the global sulfuric acid and sulfur supply chain. Since the joint US-Israeli military strike against Iran on February 28, 2026, the Strait of Hormuz, the world's most critical energy transport route, has rapidly fallen into a severe transit crisis. After taking office, Iran's new Supreme Leader, Mojtaba Khamenei, immediately declared that the strait would remain closed as a strategic lever against the US-Israeli alliance and suggested that neighboring countries close US military bases. The Islamic Revolutionary Guard Corps subsequently explicitly announced a ban on any vessels associated with the US or Israel from passing through the Strait of Hormuz, warning of severe consequences for unauthorized passage. The Strait of Hormuz is a critical chokepoint for global sulfur transport. Statistics show that before the conflict, over 100 ships passed through the strait daily. However, after the conflict erupted, transit traffic plummeted by over 90%, with extreme cases of no ships passing for an entire day, leaving over 3,000 vessels stranded in nearby waters. This effective blockade has not only directly impacted the crude oil market—with Brent crude futures rising over 50% within a month to exceed 114 USD per barrel—but has also severely disrupted the global supply chain for sulfur and sulfuric acid. War risks have caused shipping insurance costs to soar to over 20% of the cargo value, further increasing logistics costs and plunging global sulfur supply into a logistical crisis. Although Iran claims to allow passage for vessels from "non-hostile" countries, requiring them to obtain prior permission, actual transit volumes remain extremely low, far below global trade demand. Simultaneously, the Houthi armed group in Yemen has announced its involvement, posing new security threats to the Red Sea-Suez route. The compounding pressure on the two major shipping chokepoints of the Strait of Hormuz and the Red Sea is posing a systemic challenge to the global supply chains for energy and chemical raw materials. As the primary raw material for sulfuric acid production, the disruption in sulfur supply directly drives international and domestic sulfuric acid prices progressively higher. Given the current situation, geopolitical conflicts show no signs of easing in the short term, implying further room for sulfuric acid price increases. The continued rise in sulfuric acid prices will have a dual impact on the domestic copper smelting industry. On the one hand, increased sulfuric acid revenue will continue to provide crucial profit supplementation for smelters, enabling them to maintain production even at lower TC levels and potentially further depressing spot copper concentrate treatment charges. On the other hand, this surge in sulfuric acid prices, driven by geopolitical conflict, also makes smelter profitability highly dependent on external unstable factors, rendering the industry's overall risk resilience increasingly fragile. Notably, the extreme treatment charge environment has begun to have a tangible impact on the global layout of copper smelting capacity. Mitsubishi Materials of Japan recently announced its plan to cease operations at its Onahama copper smelter by the end of March 2027. The smelter has a crude and refined capacity of 230,000 tons, and the main reason for the closure is precisely the intensified competition in the global copper smelting industry, leading to a sharp deterioration in copper concentrate TC/RC and persistent pressure on business prospects. This decision sends a clear signal: against the backdrop of continuously bottoming treatment charges and industry profits highly dependent on byproducts and external environments, some high-cost smelting capacity or those lacking comprehensive recovery capabilities are facing pressure to exit the market. In summary, China's copper smelting industry is currently at a highly unusual cyclical juncture. On one hand, smelters, benefiting from high sulfuric acid prices, have temporarily weathered the impact of negative treatment charges, maintaining high output. On the other hand, sulfuric acid prices themselves are heavily dependent on geopolitical situations, and external variables like the Strait of Hormuz blockade introduce significant uncertainty into the sustainability of smelting profits. If tensions in the Middle East persist, sulfuric acid prices may continue to rise, leaving room for TC to fall further, potentially enhancing smelters' tolerance for extreme treatment charges in phases. However, if geopolitical tensions ease, sulfur supply chains recover, and sulfuric acid prices retreat from their highs, smelters would face the risk of a "double blow" from both low treatment charges and reduced byproduct revenue, potentially heralding a genuine phase of capacity reduction and deep adjustment for the industry. Therefore, the current apparent "resilience" of the copper smelting industry is essentially built upon a fragile balance between geopolitical factors and the byproduct market. For market participants, besides monitoring TC trends, it is crucial to closely track changes in sulfuric acid prices and the underlying geopolitical factors to make more accurate judgments regarding the production sustainability and profitability prospects of the smelting industry.
