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 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.

The company previously reviewed and approved an investment of approximately $231 million based on an expected 55% shareholding to construct the project. Currently, the company's equity interest in the Alacran copper-gold-silver mine has increased to 97.5%, and the company will follow the corresponding review procedures for project construction investment in accordance with the company's articles of association and make timely disclosures. Jinchengxin's Q1 2026 report disclosed on April 28 showed: The company achieved total operating revenue of 3.414 billion yuan, up 21.45% YoY; net profit attributable to the parent company was 601 million yuan, up 42.55% YoY. Regarding the reasons for the increase in Q1 operating revenue and net profit, Jinchengxin announced: This was mainly due to increased sales of mineral resource products (copper cathode, copper concentrates, iron ore) and rising copper ore product prices during the period. Jinchengxin's 2025 annual report showed: The company achieved revenue of 13.894 billion yuan in 2025, up 39.74% YoY; net profit attributable to the parent company was 2.339 billion yuan, up 47.66% YoY. Jinchengxin stated in its 2025 annual report: Operating revenue increased 39.74% YoY and net profit attributable to shareholders of the publicly listed firm increased 47.66% YoY during the period, mainly due to increased production and efficiency at captive mine projects in the mine resource development business during the reporting period. In addition, Jinchengxin stated on the interactive platform on April 28 that the company's copper ore product inventory increased at year-end 2025 and at the end of Q1 2026, mainly because the local rainy season (November–April) affected road conditions and transportation on peripheral roads of the Dikulushi copper mine in the DRC, and the produced mineral products had not yet been sold externally. China Post Securities' commentary on Jinchengxin's performance report showed: The resource segment saw volume-driven growth, while the mining services business was slightly dragged down. By business segment, the mine resource business achieved revenue/gross profit of 6.986/3.121 billion yuan in 2025, up 117.67%/130.20% YoY, while the mining services business achieved combined revenue/gross profit of 6.613/1.515 billion yuan, up 1.06%/down 13.47% YoY. The mining business saw both volume and price increases, while the decline in mining services was mainly due to the Lubambe copper mine being converted to an internal unit after acquisition, resulting in reduced recognized revenue and gross profit, and some projects being affected by declining work volumes/production ramp-up. Volume: Copper metal sales in 2025 were 92,700 mt, up 88.16% YoY; phosphate ore sales were 357,400 mt, down 1.00% YoY. The growth in copper metal production and sales was mainly due to the Lonshi copper mine reaching full production, the Dikulushi and Lonshi copper mines exceeding production plans, and the Lubambe copper mine being consolidated for the full year. In 2026Q1, copper metal production/sales were 22,400/18,100 mt, mainly affected by declining grade and the rainy season. Price: Copper prices were up 7.62% YoY in 2025 and up 36.72% YoY in 2026Q1. Production is expected to grow steadily in 2026, with significant long-term expansion potential. In 2026, the company's captive resource projects plan to produce 100,300 mt of copper metal (equivalent) and sell 99,700 mt of copper metal (equivalent), and produce and sell 300,000 mt of phosphate ore; the Yisitanxinshan magnetite project plans to produce and sell 1.25 million mt of iron ore concentrates. In the longer term, the northern mining area of the Liangchahe phosphate mine is expected to be put into use by the end of 2028, with annual capacity expanding from 300,000 mt to 800,000 mt; after the eastern zone of the Lonshi copper mine is put into production, annual production can expand from 40,000 mt to 100,000 mt; the Lubambe copper mine is undergoing technological transformation, and after completion is expected to produce 35,000 mt of copper annually; the company holds a 97.5% equity stake in the San Matias copper-gold-silver mine, which is in the EIA approval stage. Risk warnings: Price fluctuation risks; project progress falling short of expectations; downstream demand falling short of expectations; model assumptions not matching reality; policy risks exceeding expectations, etc.

Today, the most-traded BC copper contract 2606 opened at 92,520 yuan/mt, swung wildly in early trading, then fluctuated upward to probe 93,040 yuan/mt after the day session opened. Subsequently, the copper price center fluctuated downward to touch a low of 92,020 yuan/mt before fluctuating upward again, ultimately closing at 92,660 yuan/mt, up 0.42%. Open interest stood at 9,125 lots, down 263 lots from the previous trading day, with trading volume at 7,298 lots, indicating bears reducing positions. On the macro front, the US suspended its originally scheduled military action against Iran on Tuesday, and the US dollar index weakened, providing bullish support for copper prices; an Ebola outbreak emerged in the DRC, which has not yet affected core copper mining areas, but the market has begun to worry about the stability of the global copper ore supply chain. Fundamentals side, on the supply end, affected by concentrated maintenance at smelters, copper cathode arrivals in China decreased, compounded by limited imported copper replenishment, and the spot market supply was generally tight; on the demand end, as copper prices fluctuated at highs, downstream enterprises showed weak purchase willingness, with the market mostly maintaining rigid-demand purchases, and overall transactions showed no significant recovery. The SHFE copper 2606 contract closed at 104,530 yuan/mt. Based on the BC copper 2606 contract at 92,660 yuan/mt, its after-tax price was 104,705 yuan/mt. The price spread between the SHFE copper 2606 contract and BC copper was -175, maintaining an inversion that continued to widen from the previous day.

The main products include high performance copper and copper alloy strip and rolled copper foil, of which copper alloy strip capacity is 25,000 mt/year and rolled copper foil capacity is 5,000 mt/year. 2 What caused the negative operating cash flow, and what is the impact on the company going forward? North Copper responded: The negative net cash flow from operating activities in Q1 was mainly due to two reasons: first, rising non-ferrous metal prices led to higher overall value of copper raw materials, increasing capital occupation; second, under the impact of geopolitical factors, international shipping rerouting and tight domestic railway dispatching caused copper raw material arrivals at the plant to be delayed versus plan, extending the capital turnover period. The company's current cash flow level can effectively support daily operations and debt repayment. Going forward, the company will take targeted measures to improve the situation. 3 Questions regarding the progress of Hujiaoyu mine asset injection. Specifically: Has the preliminary preparation work for the asset injection (such as auditing, valuation, and plan evaluation) been initiated? Does the company plan to complete this asset injection within 2026? Are there any material obstacles or uncertainties in the process that need to be disclosed to investors? Beyond strictly fulfilling the commitment to inject within 24 months, does the company's management have a clear goal and timetable to "strive for early completion"? What specific stage has the related work progressed to? North Copper responded: Hujiaoyu Mining Company, a subsidiary of the company's controlling shareholder Zhongtiaoshan Group, obtained the mining permit for newly added reserves on March 27, 2026. Preliminary work for obtaining the mine safety production permit is currently being actively advanced, and the conditions for injection into the publicly listed firm are not yet met. The company will initiate the asset injection process in a timely manner after all the above mining permits are obtained, fulfilling the relevant commitments. 4 After the completion of the 50,000 mt rolled copper foil and strip project, are there any further plans for new copper foil capacity construction and expansion? North Copper responded: Some production lines of the company's 50,000 mt/year high performance rolled copper strip and foil and 2 million m² CCL project have not yet been completed, and capacity has not been fully released. There are currently no new copper foil capacity expansion plans. 5 How does the company's management plan to manage market capitalization?

The company's "Zhongtiaoshan" brand Grade-A copper is registered on the Shanghai Futures Exchange and the Shanghai International Energy Exchange, and the "Zhongtiaoshan" brand gold and silver ingots are registered on the Shanghai Futures Exchange. The company's mineral exploration status disclosed in North Copper's 2025 annual report showed: The company completed the detailed exploration project for deep replacement resources at the Tongkuangyu copper mine (below the 80m elevation), with the following main work completed: exploration tunnels 140.6 m, drilling chambers 12/2,823.6 m³, drilling 12 holes (including 3 hydrogeological holes), drilling volume 7,268.62 m, 1:2000 specialized hydrogeological and environmental geological survey 6 km², geophysical logging 2,065.61 m, and pumping tests on 3 holes; 8,091 sample analyses and tests, 46 sets of rock and ore tests, 99 bulk density samples, 20 copper phase analyses, 10 complete chemical analyses, and 12 complete water quality analyses. On February 20, 2025, the Shanxi Mining Association organized and completed the supervision and field acceptance of the detailed exploration project, issuing the supervision report and field acceptance report. In early March, the company completed the compilation of the Detailed Hydrogeological and Environmental Survey Report for the Deep Part of Tongkuangyu Mine. On March 17, the report was reviewed and approved by experts organized by the Shanxi Mining Association. In May, the company completed the compilation of the Detailed Exploration Report for Deep Replacement Resources at Tongkuangyu Copper Mine, Yuanqu County, Shanxi Province (hereinafter referred to as the Report). On May 23, the report was reviewed and approved by experts organized by the Shanxi Mining Association, and review opinions were issued. According to the Report, as of December 31, 2024, within the 80m to -325m elevation range of the Tongkuangyu mining area, the cumulative identified industrial ore body (No. 5) copper ore resources totaled 103.718 million mt, with an average grade of 0.84% and metal content of 869,600 mt. Associated gold metal content was 8,930 kg with an average grade of 0.09 g/t; associated molybdenum metal content was 3,727 mt with an average grade of 0.011%. Low-grade copper ore resources totaled 34.625 million mt, with an average grade of 0.25% and metal content of 88,200 mt. The explored resources reached a large scale, achieving significant exploration results and providing solid resource support for the company's industry chain layout. Regarding the company's copper ore resource reserves, North Copper disclosed in its annual report that as of the end of 2025, the Tongkuangyu mine retained copper ore resources of 4.664 million mt above the 80m elevation, with copper metal content of 1.2501 million mt. Meanwhile, below the 80m elevation at the bottom of the company's existing Tongkuangyu mine mining rights, the cumulative identified industrial ore body (No. 5) copper ore resources totaled 3.718 million mt, with an average grade of 0.84% and metal content of 869,600 mt. Regarding the 2026 production and operation plan, North Copper mentioned in its 2025 annual report: Major product production targets: copper cathode 300,000 mt, sulphuric acid 800,000 mt, gold ingots 6 mt, and silver ingots 60 mt, to maximize economic benefits. Regarding the outlook for copper, some institutions hold the following views: Tony Sage, CEO of Critical Metals, noted in a recent report that market participants remain bullish on the copper price outlook, driven by long-term demand from AI infrastructure, power grid modernization, and the global energy transition, coupled with supply constraints. He added that in the long run, the copper market may face a potential supply deficit, which will provide support for copper prices. (Jin10 Data) A CITIC Securities research report noted that as Freeport once again delayed the production resumptions schedule for its Indonesian project and comprehensively lowered its production guidance for 2026-2027, global major miners' 2026 production expectations have officially entered a decline, and the potential impact of subsequent extreme weather may further amplify supply disruptions. We expect that the solid supply-demand fundamentals demonstrated by the better-than-expected destocking in China, along with easing macro headwinds, will support copper prices to stabilize at $13,000/mt in 2Q26, while the gap between supply-demand expectations could drive copper prices to challenge previous highs. We are optimistic about the allocation opportunity in the copper sector where earnings elasticity and valuation elasticity resonate.

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."
