Macro Front China: [CSRC Vice Chairman Liu Haoling: Foreign investors' willingness to allocate to China's quality assets continues to rise] On May 28, the 2026 Global Investor Conference hosted by the Shenzhen Stock Exchange was held in Shenzhen. CSRC Vice Chairman Liu Haoling stated in his address that China's capital market reforms integrating investment and financing had progressed steadily and continued to deliver results, overall market valuations were within a reasonable range, and foreign investors' willingness to allocate to China's quality assets continued to rise. In his address, Liu Haolin stated that China is a major contributor to and stabilizing anchor for global economic growth, and a fertile ground for foreign enterprises to invest and do business. Since the beginning of this year, foreign capital has been flowing steadily into China's stock market through various channels. As of now, various overseas investors hold over 4 trillion yuan in A-share tradable market capitalization, making them important participants in China's capital market. (Wallstreetcn) PBOC conducted 101.3 billion yuan of 7-day reverse repo operations in the open market, with the operation rate at 1.40%, unchanged from the previous day. Today, 100 billion yuan of reverse repos matured. US dollar: As of 11:39, the US dollar index rose 0.25% to 99.48. Persistently high energy prices intensified market concerns about a resurgence in inflation. Chicago Fed President Goolsbee on Thursday further reinforced his warning: rising market expectations for AI's potential to boost productivity could push up inflation and force the US Fed and other central banks to raise interest rates. Goolsbee said: "The more hype there is about future productivity, the higher rates may need to go to prevent the economy from overheating. More importantly, facing supply shocks in the short term—whether from oil prices, supply chain disruptions, or other factors—makes the problem even worse." The above remarks further expanded on the views Goolsbee first publicly raised earlier this month. He questioned the notion that AI could suppress inflation and thereby create room for central banks to cut interest rates—a view championed by many officials in the Trump administration as well as new US Fed Chair Warsh. In the 1990s, as computers became more widely adopted, US productivity rose unexpectedly, driving rapid economic growth without triggering inflation. However, Goolsbee argued that if productivity gains are anticipated by the market, the situation would be different. Markets could trigger a spending boom in advance, pushing up prices before actual productivity gains materialize. US Fed Vice Chair Jefferson said he expected inflation to cool later this year as the effects of tariffs and rising energy costs fade, but he warned that inflation risks remain tilted to the upside. In remarks prepared for delivery at a Bank of Japan-hosted conference in Tokyo on Thursday morning, Jefferson said he is watching for signs that rising energy costs from the Iran war are weighing on consumer spending. He also warned that he continued to see signs of weakness in the labour market. Jefferson reiterated his view that the central bank's current policy stance was well positioned to respond to any developments. Jefferson stated, "I am not prejudging the next meeting and look forward to engaging with my colleagues on the best policy to achieve our dual mandate goals." (Jin10 Data) Other currencies: The Bank of Korea's six-month dot plot showed that among 21 dots, 7 were at 2.75%, 10 at 3%, 2 at 3.25%, and 2 at 2.5%.

Crude oil: As of 11:39, both benchmarks rose, with WTI up 3.1% and Brent up 3.07%. US-Iran tensions escalated again, driving crude oil higher. US President Trump expressed dissatisfaction with negotiations with Iran, and the White House subsequently denied Iranian media reports of progress in peace talks, quickly dampening earlier market optimism about a ceasefire agreement. The US-Iran conflict entered its fourth month, with ceasefire prospects remaining uncertain. According to Xinhua News Agency, US President Trump said at a cabinet meeting at the White House on the 27th that the US and Iran had not yet reached a deal and the US was "dissatisfied" with this, fully rejecting the potential mechanism for joint US-Iran-Oman management of the Strait of Hormuz. (Wallstreetcn) The American Petroleum Institute (API) released data showing that US crude oil and gasoline inventories both declined last week. US API crude oil inventory for the week ending May 22 was -2.819 million barrels, versus expectations of -4.367 million barrels and a prior value of -9.11 million barrels. US API gasoline inventory for the week ending May 22 was -3.199 million barrels, versus expectations of -2.896 million barrels and a prior value of -5.795 million barrels.

May 20, 2026 At first glance, the price of silver appears to be stuck in a rut, with a sustained breakout above stubborn resistance levels still a long way off. But this calm is deceptive: according to experts, an environment is brewing beneath the surface of the financial system that could provide precious metals with massive tailwinds in the coming quarters. While stock markets near record highs give many investors a false sense of security, systemic risks are growing. This opens up an exciting prospect for commodity investors: The signs of a major shift in capital—away from overvalued growth stocks and toward tangible assets—are becoming increasingly evident. Between inflationary pressure and tight supply A key driver of this scenario is persistent inflation. Geopolitical tensions and oil prices above $100 per barrel are fueling inflation and limiting central banks’ room to maneuver. Even with a weakening economy, an aggressive interest rate cut policy is nearly impossible under these conditions. For the silver market, this is a double catalyst: On the one hand, high energy costs are driving up mining operators’ expenses, which makes production more expensive and constricts supply. On the other hand, in an inflationary, uncertain environment, the appeal of real assets—which cannot be multiplied at will—is growing. The interest rate trap for tech stocks as a catalyst However, analysts see the real powder keg in the bond markets. Long-term U.S. Treasury bonds with yields above 5 percent are increasingly becoming a threat to highly valued tech stocks. Their enormous market capitalizations are heavily based on profits that lie far in the future. If interest rates remain persistently high, this valuation logic will deteriorate drastically. This is precisely where experts see the trigger for the so-called “great rotation”: as soon as capital is withdrawn from highly valued tech stocks, it must find new investment targets. Commodities, precious metals, and domestic producers would be the primary beneficiaries of this shift. Future Fed Chair Kevin Warsh faces a balancing act: He must stabilize the banking system while simultaneously withdrawing liquidity from the market to reduce the Federal Reserve’s balance sheet—a scenario that traditionally boosts physical silver and gold. Systemic risks bring physical assets into focus In addition to monetary policy, a growing loss of confidence in traditional financial assets supports the thesis of the precious metals bulls. High interest rates are putting massive pressure on highly indebted companies and the private credit sector. When stocks and bonds lose stability and the banking system appears more fragile, investors seek independence. In a highly leveraged environment, gold and silver offer precisely the advantage of not being dependent on the creditworthiness of third parties. International currency concerns also underpin this trend. India’s recent attempts to curb precious metal imports are a clear symptom of global anxiety about currency stability and the desire to preserve capital. Conclusion : The silver price is still in a consolidation phase. But if inflationary pressures, credit risks, and geopolitical tensions continue to intensify, the current market is not the end of the line, but rather the foundation for a revaluation, according to market experts. The looming rotation away from tech stocks toward real assets could be exactly the spark that catapults the silver price into a dynamic upward trend.

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?

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.

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.
