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. On June 15, North Copper stated on the interaction platform in response to an investor's question that, relying on scientific research breakthroughs at the Shanxi Provincial Key Laboratory of New Copper-based Materials, the company's copper strip and foil product structure is undergoing further adjustment and optimization. All production and operation activities are proceeding in an orderly manner, and product orders are growing steadily. On June 4, North Copper stated on the interaction platform in response to an investor's question that the company's management places high importance on extending the industry chain and has made positive progress in deep copper processing. During the 15th Five-Year Plan period, the company will rely on its existing copper strip and foil production lines to achieve new breakthroughs in scientific research, product structure adjustment, and capacity enhancement, thereby empowering the company's high-quality development.

The company's 'Zhongtiaoshan' brand Grade A copper is registered on the Shanghai Futures Exchange and the Shanghai International Energy Exchange, and its 'Zhongtiaoshan' brand gold and silver ingots are registered on the Shanghai Futures Exchange. The mineral exploration situation disclosed in North Copper's 2025 annual report showed that the company completed the detailed survey project of deep-seated replacement resources at the Tongkuangyu Copper Mine (below 80m elevation), with primary completed workloads: prospecting roadway 140.6m, 12 drill chambers/2,823.6m³, 12 drill holes (including 3 hydrogeological holes), drilling footage 7,268.62m, 1:2000 special hydrogeological, engineering geological, and environmental geological survey 6㎢, geophysical logging 2,065.61m, and pumping tests for 3 holes; 8,091 samples analyzed and tested, 46 rock/mineral test groups, 99 small-weight samples, 20 copper phase analysis samples, 10 complete chemical analysis samples, and 12 complete water quality analysis samples. On February 20, 2025, the Shanxi Mining Association organized the completion of supervision and field acceptance work for the resource detailed survey project, issuing supervision and field acceptance reports. In early March, the company completed the compilation of the 'Special Hydrogeological, Engineering Geological and Environmental Geological Detailed Survey Report for the Deep Part of the Tongkuangyu Mine'. On March 17, the Shanxi Mining Association organized an expert review which was passed. In May, the company completed the compilation of the 'Detailed Survey Report on Deep-seated Replacement Resources at the Tongkuangyu Copper Mine in Yuanqu County, Shanxi Province' (hereinafter referred to as the report). On May 23, the Shanxi Mining Association organized an expert review which was passed, and an review opinion was issued. According to the report, as of December 31, 2024, within the 80m to -325m elevation range of the Tongkuangyu mining area, cumulative identified industrial orebody (No. 5) resources amounted to 103.718 million mt of copper ore with an average grade of 0.84% and a metal content of 869,600 mt. Associated gold metal content was 8,930 kg at an avg. grade of 0.09g/t; associated molybdenum metal content was 3,727 mt at an avg. grade of 0.011%. Low-grade copper ore resources amounted to 34.625 million mt with an avg. grade of 0.25% and a metal content of 88,200 mt. The scale of discovered resources reached large-size, marking a significant prospecting achievement and providing a solid resource guarantee for the company's industry chain layout. Regarding the company's copper ore resource reserves, North Copper announced in its annual report, As of year-end 2025, the Tongkuangyu Mine had retained copper ore resources above 80m elevation of 204.664 million mt, with a copper metal content of 1.2501 million mt. Additionally, below 80m elevation at the base of the Tongkuangyu Mine's current mining right, the cumulative identified industrial orebody (No. 5) copper ore resources was 103.718 million mt, with an average grade of 0.84% and a metal content of 869,600 mt. For the 2026 production and operation plan, North Copper mentioned in its 2025 annual report: Main product production: copper cathode 300,000 mt, sulphuric acid 800,000 mt, gold ingots 6 mt, silver ingots 60 mt, to maximize economic benefits. A research report from Huaxi Securities on June 14 pointed out: In the medium and long term, copper, as a key metal for energy transition, possesses strategic allocation value under the policy guidance of the 15th Five-Year Plan. On the supply side, entering 2026, major mines globally have continued to experience strikes and production halts this year, keeping the supply profile relatively tight. From a macro perspective, the probability of a US Fed interest rate cut during the year still exists. In the long term, the macro environment supports copper prices, and the US dollar is expected to continue depreciating, supporting a positive outlook on copper prices. Furthermore, strong supply-demand fundamentals support copper prices. China's macro policies are expected to continue exerting force, and stimulus measures in sectors like electric power infrastructure, NEVs, and home appliance consumption could further expand.

SMM News Release, June 22 According to customs data, China’s total exports of tungsten smelting products and tungsten materials reached approximately 1,063.6 tons in May 2026, down 11.9% month-on-month and 17.9% year-on-year.

Jusheng Light Alloy specializes in the production of high-performance aluminum alloy plates, strips, and foils, along with the processing of related products, and has achieved an output value of 470 million yuan. Since establishing a cooperative relationship with North China Aluminum, it has successfully brought in a professional management team of over 20 people. This team is helping the company expand its product portfolio into emerging fields such as NEV aluminum foil, with a target of exceeding 1 billion yuan in output value within the year.

The total investment of the Chalco Aluminum Foil New Energy High-Precision Plate, Sheet, Strip and Foil Project is RMB 1.82 billion, and physical progress has currently reached 40%. The roofing of the factory building will be completed by June 30 this year, and equipment commissioning and acceptance will be finished by month-end December, followed by trial production. It is understood that the project is expected to be officially completed and put into operation on May 31, 2027. After commissioning, it will achieve an annual output of 170,000 mt of high-precision aluminum plate/sheet, strip and foil, primarily used for the positive electrode current collectors of high-end power batteries, with an output value projected to reach 4 billion yuan.

This week, the operating rate of China's downstream aluminum processing industry leaders was recorded at 64%, edging down 0.1 percentage point WoW, with significant divergence across sub-sectors. The operating rate of primary aluminum alloy edged up 1.2 percentage points WoW to 59.4%; although supply remained normal, demand recovery was slow, and the rate is expected to hold steady in the short term. The operating rate of aluminum plate/sheet and strip edged down 0.2 percentage points to 72.0%, with robust export orders offsetting weak domestic demand caused by high aluminum prices. The operating rates of aluminum wire and cable and aluminum extrusion held flat at 68.0% and 57.6% respectively; aluminum wire and cable benefited from a significant increase in aluminum stranded wire exports. Extrusion side, steady growth in home decoration orders partially offset the drag from weak real estate recovery, while industrial extrusion demand remained solid, expected to hold up well in the short term. The operating rates of aluminum foil and secondary aluminum producers declined 0.3 and 1 percentage point respectively to 73.3% and 53.9%, affected by multiple factors including fading peak season, air-conditioner foil drag, bill supervision tightening, and weakening demand, facing sustained downward pressure going forward. Overall, strong exports partially compensated for insufficient domestic demand, but high aluminum prices, cost pressure, and off-season factors continued to constrain the industry's upside room. Primary aluminum alloy: This week, the operating rate of China's industry leaders in primary aluminum alloy rose 1.2 percentage points WoW to 59.4%. Supply side, enterprises maintained normal production schedules overall. Some enterprises saw operating rates rebound recently as prior inventory had been largely depleted. Demand side, the aluminum price center shifted lower this month MoM, but downstream spot order quotes remained generally scarce, with the market primarily executing long-term contracts as usual. As downstream demand recovered slowly, primary aluminum alloy enterprises intensified competition for limited orders, leading to a slight increase in overall inventory. Overall, with aluminum prices maintaining current levels, the stimulus effect on downstream consumption remained limited. The operating rate of the primary aluminum alloy industry is expected to stay at current levels, likely remaining stable next week. Aluminum plate/sheet and strip: This week, the operating rate of aluminum plate/sheet and strip industry leaders edged down 0.2 percentage points WoW to 72.0%. Operations side, plate/sheet, strip and foil industry leaders maintained a generally stable production pace, but disrupted shipment pace had not yet eased due to persistently high aluminum prices and downstream speculative purchasing patterns. Orders side, stable domestic can stock packaging demand provided a floor; ESS sector battery casings, brazing materials and other products maintained high operating rates as downstream orders extended into Q3, forming a key support; auto sheets benefited from MoM rebound in new energy vehicle sales in May and strong exports, with orders recovering at the margin. Export side, a stronger overseas market significantly benefited China's exports, with enterprises reporting export orders already extended to late August and beyond, with full orders on hand. However, the domestic commodity plate market faced a severe situation: aluminum ingot average prices had long operated at a high level of 24,000 yuan/mt, civilian aluminum semis demand contracted sharply, fixed-price engineering orders were widely delayed as picking up goods meant immediate losses, and domestic orders showed signs of weakening. In the short term, although strong exports could offset some weak domestic demand, aluminum price fluctuation risks intensified, and enterprises tended to control production schedule pace while destocking simultaneously. The operating rate of aluminum plate/sheet and strip is expected to be under pressure in June. Aluminum wire and cable: The domestic aluminum wire and cable industry operating rate held steady at 68.0% this week, flat WoW. The industry operating rate stayed high during the week, mainly supported by strong export order activity. Resilient ex-China demand continued to drive enterprise production plans, and near-term industry orders remained focused on aluminum stranded wire export orders. In contrast, domestically, the pace of power grid construction project order placement was slower than expected at the beginning of the year. Recent power grid tenders were dominated by low-voltage and overhead lines, and the marginal boost from order production schedules to operating rates weakened. However, sustained volume growth in export orders effectively filled the gap in domestic demand, and the order structure continued to show a pattern of "strong exports, stable domestic." Under the current dynamic between high export growth and stable domestic demand, industry shipments maintained a dynamic balance, and operating rates are expected to remain resilient in the near term. Aluminum extrusion: The domestic aluminum extrusion operating rate held steady at 57.6% this week, with the industry continuing a mild operating trend overall. On the architectural extrusion side, home renovation orders maintained steady incremental growth recently. Combined with some enterprises having previously secured large-scale project orders such as supertall buildings and corporate headquarters, their volume advantage and longer delivery cycles provided sustained support for industry operations, partially offsetting the drag from weak real estate recovery. On the industrial extrusion side, demand in segments such as power systems, automotive lightweighting, and PV frames remained solid, supporting stable industry operations. Multiple large enterprises reported that May orders remained robust and held an optimistic outlook for June orders. However, some small and mid-sized industrial extrusion enterprises reported that to maintain healthy cash flow, they expect to moderately control order-taking to ease finished product inventory pressure. Some enterprises also proactively declined orders with low processing fees to maintain reasonable margins, leading to slight divergence in industry operations. Overall, off-season characteristics had not yet emerged, and the aluminum extrusion operating rate is expected to continue to hold up well next week. Aluminum foil: The operating rate of aluminum foil industry leaders pulled back 0.3 percentage points WoW to 73.3% this week. At the enterprise operation level, the traditional peak-season effect was gradually fading. Although orders on hand at industry leaders remained ample, structural divergence intensified. On the order side, demand for food packaging foil and pharmaceutical foil was at the tail end of the peak season, and domestic orders were set to face a seasonal pullback. Battery foil, on the other hand, benefited from robust battery end-use demand, with tight production schedules. However, the air-conditioner foil segment faced notable pressure: June household air conditioner domestic sales production schedules were sharply revised down YoY, downstream clients bargained aggressively, hydrophilic foil processing fees were running near cost, and the air-conditioner foil segment entered a downturn earlier than in previous years. In June, the packaging off-season effect and the drag from air-conditioner foil are expected to gradually dominate, with operating rates continuing to pull back. Secondary Aluminum: This week, the operating rate of secondary aluminum industry leaders fell 1 percentage point WoW to 53.9%, mainly weighed down by dual pressures from both the cost and demand sides. Cost side, invoice regulation continued to tighten with an expanded scope, and the shortage of compliant input invoices forced some secondary aluminum producers to cut production, significantly dampening their willingness to operate. Demand side, downstream consumption weakened further after June, with new orders for die-casting remaining sluggish. Although ADC12 prices were raised consecutively at the beginning of the week driven by costs, downstream buyers showed limited acceptance of high prices, restocking mainly on rigid demand with little willingness to rush to buy amid continuous price rise, and transaction volumes failed to increase in tandem. Overall, if invoice issues continue to escalate and the off-season deepens further, the industry operating rate still faces downward pressure.

According to customs data, China's aluminum plate/sheet and strip (tariff codes 76061121, 76061129, 76061191, 76061199, 76061220, 76061230, 76061251, 76061259, 76061290, 76069100, 76069200) exports totaled 327,900 mt in April 2026, up 18% MoM and up 18% YoY.

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"?

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.

[Geopolitical Disruptions Combined with Elevated Inventory Highlight LME Outperforming SHFE in Aluminum Market] Overall, the core pattern of LME outperforming SHFE in the aluminum market is difficult to reverse in the short term. LME strength will support room for SHFE aluminum to catch up after the holiday, but high domestic inventory and weak demand will cap overall gains. Going forward, the focus will be on the pace of aluminum ingot destocking in China and the strength of rigid demand release from downstream resumption of work and production resumptions.
