When asked, "What are the technological content and barriers of the company's rolled copper foil? Who are the domestic and international competitors? Which companies are downstream clients?" North Copper responded on the investor interaction platform on June 25: The technological content and barriers of the company's rolled copper foil are reflected in: 1. The long process flow of rolled copper foil, involving disciplines such as smelting, rolling, metal heat treatment, and electrochemistry, requires continuous trial production to accumulate a process database. This represents a long-term experiential barrier that cannot be quickly reverse-engineered. 2. Capital and hardware thresholds, with extremely high equipment investment, high barriers for equipment installation, commissioning, and operation, and severe limitations on product width and ultra-thin gauge. 3. Barriers in rolling and forming processes, which are also the highest thresholds—covering product thickness, sheet flatness, internal structure, and mechanical properties, as well as the synergistic barriers of dozens of interconnected processing steps. The consistency control across the entire process is far more demanding than the single-step electrodeposition process for copper cathode foil. Regarding the statement, "The CCL construction portion of the company's 50,000 mt high-performance rolled copper foil and 2 million m² copper clad laminate (CCL) project has not yet commenced due to insufficient relevant technology and talent reserves, out of prudence. Next, the company will decide on the CCL investment and construction plan based on thorough market surveys and scientific validation," North Copper responded on the investor interaction platform on June 25: The CCL construction portion of the company's 50,000 mt high-performance rolled copper foil and 2 million m² CCL project has not yet commenced due to insufficient relevant technology and talent reserves, out of prudence. Next, the company will decide on the CCL investment and construction plan based on thorough market surveys and scientific validation. North Copper responded on the investor interaction platform on June 25: The company seizes market opportunities, closely monitors downstream market demand, focuses on R&D for mid-to-high-end copper strip products and structural adjustments for rolled copper foil products, and is committed to filling gaps in its process lines and reaching its capacity standard, striving to turn losses into profits as soon as possible. Regarding the question, "When will the company's semi-annual report performance forecast announcement be released?", North Copper responded on the investor interaction platform on June 25: The company has scheduled the disclosure of its 2026 semi-annual report for August 27. If the conditions for a performance forecast are met, the company will release the announcement within the stipulated time. When asked, "After the implementation of the 'Regulations on the Implementation of the Mineral Resources Law of the People's Republic of China', has the related work on applying for the mining permit for the newly added copper ore at the Tongkuangyu Mine been accelerated? Could you discuss the company's near-term plans? If progress goes smoothly, based on the ore's copper grade and after deducting relevant costs, how much profit is this expected to bring to the company?" North Copper responded on the investor interaction platform on June 24: The detailed survey of deep-seated replacement resources at the Tongkuangyu Mine is a project to add reserves outside the current mining right's boundary at depth (elevation range: 80m to -325m), which is conducive to increasing the company's copper resource reserves and extending the mine's service life. Given that the replacement resources identified by the detailed survey have reached a large scale, according to reserve review and filing requirements, the exploration level must be achieved for resource reserve filing and for initiating the transition from exploration to mining. As the mine's production level shifts downward, the company will conduct further exploration work for deep-seated replacement resources at the next production level. The company currently has no relevant deep exploration plans. Regarding the question, "As a third-generation core substrate material for IC lead frames, could you briefly introduce the production and latest order status of your company's 5,000 mt chromium zirconium copper alloy product?", North Copper responded on the investor interaction platform on June 23: Our company has completed the casting ingot product for C18150 (chromium zirconium copper alloy); the subsequent copper strip process is currently under trial production. There are no orders at present. On June 17, North Copper stated on the interaction platform in response to an investor's question that the company has not yet established a cooperative relationship with NVIDIA. On June 17, North Copper stated on the interaction platform in response to an investor's question that the company has a comprehensive market cap management system, consistently centering market cap management on enhancing intrinsic value. Through methods such as focusing on core business growth, optimizing governance structures, strengthening information disclosure, and implementing shareholder return plans, it is committed to achieving long-term alignment between the company's value and its market performance. Should there be arrangements such as share buybacks or capital increase plans, the company will promptly issue relevant announcements.

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?

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.
