When asked, "What were the sales volume and pricing of copper foil produced by your company in April 2026?" North Copper responded on May 19 via the investor interaction platform: The company's copper foil sales are performing well with balanced production and sales; the product is priced and sold on a market-based basis according to market supply and demand. North Copper also responded on May 19: The company's share price fluctuations are influenced by a combination of factors including the macro environment, market sentiment, capital flows, and the company's own performance. The recent share price fluctuations have been largely in line with the trend of publicly listed firms in the copper sector. The company has always focused on enhancing intrinsic value as the core of its market capitalization management, and is committed to the long-term alignment of corporate value and market performance through focusing on core business growth, optimizing governance structure, strengthening information disclosure, and implementing shareholder return plans. The content of the earnings briefing announced by North Copper on May 8 showed: 1 What is the current construction progress of the new 10kt rolled copper foil production line, and in which month of 2026 is it expected to be completed? 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 reached the intended usable condition. 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? North Copper responded: In accordance with the requirements of Regulatory Guidelines for Listed Companies No. 10 — Market Capitalization Management, the company will make comprehensive utilization of lawful and compliant methods, promote positive interaction between value and market capitalization through improving operational quality, strengthening information disclosure, and deepening investor communication, continuously improve and strengthen market capitalization management, and carry out scientific, effective, and compliant market capitalization management practices. 6 Given the strong Q1 2026 results, the share price has underperformed peers with weaker results. Does the company have any undisclosed adverse events? North Copper responded: In addition to operating performance, the company's share price is also influenced by various factors including the international situation, policy environment, financial market liquidity, capital market atmosphere, and investor psychological expectations. The company strictly fulfills its information disclosure obligations in accordance with relevant laws and regulations, and there are no material matters that should have been disclosed but were not. 7 What new progress will the company make in smart mines and digital factories this year? North Copper responded: The company will continue to advance the construction of smart mines and digital factories, deepen and expand new scenarios for digital-intelligent integration applications, and accelerate the implementation of the Tongkuangyu mine smart mine project. Within the year, the company plans to complete the installation of system equipment for the data center, integrated management and control hall, and other facilities.

It also recovers valuable metals including platinum, palladium, selenium, and bismuth through comprehensive utilization. Copper deep-processing 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. The company has established an integrated industry chain from mining, ore beneficiation, smelting to rolling processing. 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.

SMM May 15 News: In May 2026, the global molybdenum market remained in a persistently tight supply-demand pattern, with prices extending and accelerating the upward trend seen in April. International molybdenum oxide prices kept surging at high levels, while domestic molybdenum concentrate and ferromolybdenum prices repeatedly hit new stage highs.

Recently, China’s domestic rhenium market has seen a mild price correction, with prices of raw materials and metal products weakening in tandem. In contrast, overseas rhenium prices have moved higher against the domestic trend, highlighting a clear divergence between domestic and overseas markets. At present, the industrial chain remains in an obvious price game. Upstream sellers hold a cautious shipping attitude and mainly conclude small-volume rigid-demand deals, while downstream buyers stay on the sidelines with a strong willingness to press prices and test the bottom. Overall market trading activity is sluggish, and rhenium prices are expected to move in a range-bound consolidation in the short term. Differing from the downward trend in the domestic market, the overseas rhenium market has maintained a steady upward momentum with continuous gains in overseas quotations. Currently, the overseas price of ammonium rhenate has climbed to around USD 5,300, and the overseas price of rhenium pellets has risen synchronously to USD 375 per troy ounce. Supported by relatively resilient overseas demand and tight supply circulation overseas, rhenium product prices have kept advancing. A stark contrast has formed between domestic and overseas market trends, and the price spread pattern has also changed accordingly. From the perspective of industrial chain fundamentals, the price game atmosphere in the rhenium market remains intense, presenting a two-sided pattern of cautious holding by sellers and price bottom-hunting by buyers. Domestic copper and molybdenum producers are generally prudent in shipments, holding positive expectations for future prices and reluctant to release large volumes of goods at blindly low prices. Most players adopt a strategy of small-batch and demand-based partial shipments, with overall supply release remaining restrained. Downstream metal processors and end-user enterprises hold a low-price procurement mentality. Amid the market correction, their wait-and-see sentiment has intensified, and they are unwilling to build large inventories. Buyers continue to test sellers’ room for price concessions, and purchase-on-demand has become the mainstream market pattern. Overall, the domestic rhenium market lacks major positive catalysts at this stage, leaving raw material and product prices room for weak range-bound volatility in the short term. High overseas market prices offer limited support to domestic prices. The upstream-downstream price game is unlikely to ease in the near term. Without the concentrated release of new rigid demand and price support from the raw material end, domestic rhenium prices are projected to maintain a weak range-bound trend. Market transactions will continue to be dominated by small rigid-demand orders. It is necessary to keep track of the transaction rhythm between upstream and downstream players, changes in raw material inventories, and the transmission impact of overseas price movements on the domestic market. Looking at the domestic raw material market, the price center of rhenium raw materials has moved down recently. Major domestic copper-molybdenum smelters offer rhenium products mainly at CNY 26,000–27,000 per kilogram, with most market transactions settled within this range. Meanwhile, market supply structure has become differentiated. Some small and medium-sized producers adopt low-price shipments to capital 回收，with actual transaction prices falling to CNY 24,000–25,000 per kilogram. The circulation of low-price supplies has dragged down spot market prices and further deepened the correction of raw material prices. The metallic rhenium market adjusted in line with raw material trends. Rhenium pellet prices edged down alongside raw materials, with mainstream current transaction prices standing at around CNY 46,000 per kilogram. On the whole, the metal end shows a strong correlation with raw material price movements. In the absence of major positive drivers, downstream consumption is confined to industrial rigid demand, which is insufficient to drive a steady rebound in product prices. Market quotations adjust flexibly following spot trading sentiment.

[Molybdenum News Flash] SMM May 14: A steel mill in Liaoning priced its ferromolybdenum tender at 324,000 yuan/mt on May 14, payment by bank acceptance. A steel mill in Hebei's ferromolybdenum tender on May 13 ultimately failed.

[Molybdenum Flash] SMM May 14: On May 14, a mine in Jiangxi sold 128 mt of molybdenum concentrates with a grade of 45%-50% (average copper 1.72%, average phosphorus 0.077%). The auction transaction price was 5,230 yuan/mtu, with a reserve price of 5,230 yuan/mtu, settled at 35% cash and 65% bank acceptance.

[Tungsten News Flash] The Ministry of Natural Resources released a batch of new-round mineral exploration breakthrough results on May 13. The Xiaoliugou deposit in Gansu added 27,600 mt of WO₃ tungsten resources, representing a significant increment to China's strategic mineral reserves. Project: Detailed exploration of the Shiji ore section, Xiaoliugou mining area, Sunan, Gansu; Mining right holder: Gansu Xinzhou Mining; Resources: WO₃ 27,600 mt (14,800 mt indicated + 12,800 mt inferred); Concurrently announced were multiple major exploration breakthroughs including gold-arsenic in Jilin, chromium-nickel-cobalt-copper-molybdenum-silver in Tibet, gold in Sichuan, and oil and gas in Sichuan (natural gas / helium / shale gas).

According to SMM, the latest 316L grade extra fee in Indonesia has risen to $2,100/t, up $200/t from the previous level of $1,900/t. The increase was mainly driven by higher molybdenum costs. As 316L is more sensitive to molybdenum input costs, the rise in moly prices has pushed the grade extra higher and continues to support pricing for high-alloy stainless steel in Indonesia.

[Industrial Advantages] The nonferrous metals industry is the largest pillar industry of Jiangxi Province. The energy consumption dual controls, dual carbon policies, and the new connotations of high-quality development have put forward new requirements for strengthening and expanding the nonferrous metals industry. Promoting the further healthy, rapid, and orderly development of the nonferrous metals industry and enhancing its core competitiveness is an inevitable requirement for transforming from a province rich in nonferrous metal resources to a province with a strong nonferrous metals industry, and is also an important lever for Jiangxi to achieve carbon peaking by 2030. Leveraging Jiangxi Province's abundant nonferrous mineral resources, Jiangxi's nonferrous metals industry has developed rapidly, with continuously expanding scale and improving standards. It has become Jiangxi's largest pillar industry and is currently a key "trillion-yuan-level" industry being cultivated in Jiangxi. It is the undisputed "ballast stone" of Jiangxi's manufacturing sector. Jiangxi has become an important nonferrous metal ore mining and production site in China. Jiangxi Province enjoys superior metallogenic geological conditions and abundant mineral resources, making it one of China's important bases for nonferrous metals, rare metals, rare earth, and uranium minerals, with a relatively high degree of mineral resource complementarity. Jiangxi's seven major categories of minerals — copper, tungsten, rare earth, uranium, tantalum-niobium, gold, and silver — are known as the "Seven Golden Flowers." According to Jiangxi Province's "2+6+N" Action Plan for High-Quality Leapfrog Industrial Development, the province's nonferrous metals industry plans to achieve a trillion-yuan level in main business revenue. To promote the healthy development of Jiangxi Province's nonferrous metals industry, facilitate foreign economic and trade cooperation, and guide Jiangxi's nonferrous metals industry to align with international standards, the Organizing Committee, after conducting multiple in-depth grassroots surveys and project analyses with government authorities and industry associations, has decided to hold the "4th China (Jiangxi) International Nonferrous Metals and Metallurgical Industry Exhibition, 2027" at the Nanchang Greenland International Expo Center on March 28-30, 2027.
