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?

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.

"Tin" Leads the Future: Industrial Transformation and Value Reshaping in a New Cycle **Conference Background** Currently, the global tin industry stands at a historic turning point, where traditional cyclical logic has been fundamentally disrupted and strategic value has become fully prominent. The tin market in 2026 presents an unprecedented complex landscape and profound transformation: **I. Deep Restructuring of the Supply-Demand Pattern with Unprecedented Elevation of Strategic Attributes** The global static reserve-to-production ratio of tin resources is only 14 years, with scarcity becoming increasingly prominent. The supply side faces "triple pressures": repeated setbacks in Myanmar's production resumptions, continued policy tightening in Indonesia, and elevated geopolitical risks in the DRC — resource constraints have become the new normal. Meanwhile, the demand structure has undergone a fundamental shift, and tin has become a strategic resource connecting traditional manufacturing with the digital future. **II. Price System Breaking Historical Records with the Industrial Ecosystem Facing Reshaping** In early 2026, SHFE tin prices broke through 470,000 yuan/mt, hitting a record high. This price breakthrough is not only a reflection of supply-demand imbalance but also a hallmark of the value reassessment of the tin industry. Traditional trade models, risk management systems, and supply chain collaboration approaches all urgently require innovative breakthroughs. **III. Technology-Driven and Green Transformation Fostering a New Symbiotic Ecosystem** Digital and intelligent technologies are deeply empowering the tin industry chain. The global green transformation requires the tin industry to upgrade toward low-carbonisation and circular economy models, making secondary tin recycling and green smelting processes an inevitable path. All segments of the industry chain must shift from competition to collaboration, building an open, resilient, and innovative symbiotic system.
