On May 28, JX Advanced Metals, Mitsubishi Materials (MMC), Mitsui Kinzoku, and Marubeni signed a final agreement to integrate MMC’s copper concentrate procurement and sales of cathode copper, sulfuric acid, and other by-products into Pan Pacific Copper (PPC), while establishing a wholly-owned subsidiary, "PPC Material." The integration will be executed via a company split: PPC first absorbs the target business, then transfers it to the newly established PPC Material on the same day. Originally planned for end-March, the process was delayed by about two months due to detailed discussions. Post-integration, PPC’s ownership stands at: JX 32.50%, MMC 32.00%, Mitsui Kinzoku 21.90%, and Marubeni 13.60%. PPC becomes an equity-method affiliate of all four companies, with PPC Material as its wholly-owned subsidiary. Currently, PPC subcontracts smelting/refining to JX Metal Smelting and Hibi Smelting; after the deal, MMC will also become a subcontractor. Japan’s copper concentrate procurement windows will shrink from three to two, held by Sumitomo Metal Mining and PPC Material. The move aims to counter intensifying overseas competition and sharply deteriorated TC/RC through centralized procurement and cost efficiency. The transaction is planned for October 1, 2026, pending regulatory approvals.

[Hawkish US Fed Expectations Heat Up, Aluminum Prices Under Pressure and in the Doldrums] On the fundamentals, the tight spot cargo situation in the ex-China aluminum market continued. LME aluminum inventory remained at low levels, cancelled warrants continued to grow, reflecting tight available supplies. Meanwhile, Japan's Q3 spot aluminum premiums were further raised, also indicating resilient Asian spot demand. Multiple factors jointly supported LME aluminum's performance. On the China side, driven by improved export margins, aluminum semis exports recovered and are expected to remain at a relatively high level in the near term. However, the pace of China's inventory drawdown was slow, spot transactions were lackluster, and downstream purchasing remained cautious, limiting SHFE aluminum's upside room. Overall, aluminum prices are expected to continue moving sideways with LME outperforming SHFE in the near term.

(CCTV News) US dollar: Overnight, the US dollar index rose 0.08% to 99.23. 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 warned that inflation risks remain tilted to the upside. In prepared remarks for a speech at a Bank of Japan-hosted conference in Tokyo on Thursday morning, Jefferson said he was watching for signs that rising energy costs from the Iran war were dragging on consumer spending. He also warned that he continued to see signs of labour market weakness. Jefferson reiterated his view that the central bank's current policy stance is well positioned to respond to any developments. Jefferson said, "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." According to CME "FedWatch": the probability of the US Fed maintaining rates unchanged through June is 99.9%, with a 0.1% probability of a cumulative 25 basis point interest rate cut. The probability of the US Fed maintaining rates unchanged through July is 91.4%, with an 8.5% probability of a cumulative 25 basis point rate hike. US Fed Governor Lisa Cook said in a speech at a Stanford University event on Wednesday local time that inflation is moving in the wrong direction, and she is prepared to raise interest rates if this continues. While Cook said she currently favors keeping borrowing costs unchanged and expects price growth to cool again in the coming months, her remarks align her with many US Fed officials' view that accelerating inflation is now a bigger policy concern than the labour market. Cook said: "I want to be clear about my risk assessment: risks remain tilted toward higher inflation." Cook said that inflation above the US Fed's 2% target for five years poses the risk of price pressures becoming embedded in price and wage-setting behavior. "Therefore, if the expected inflation pullback does not materialize in a timely manner, I am prepared to raise interest rates," she said.

Crude oil: Overnight, both oil futures fell, with WTI down 4.77% and Brent down 3.92%. The prospects for US-Iran talks remain uncertain. After the decline on the 27th, WTI crude oil edged up at the open on May 28, as the US and Iran still have disagreements on how to reopen the Strait of Hormuz. Trump said he was "not satisfied" with the negotiations. The White House denied Iranian reports of a draft agreement that said Iran and Oman would oversee strait shipping. Despite the challenges, crude oil prices are still on track for a second consecutive weekly decline due to optimism that the warring parties can at least reach an interim agreement. The sticking points in these protracted negotiations include Iran's desire to retain control over the Strait of Hormuz and the fate of the country's nuclear program. (Jin10 Data APP) According to CCTV News, earlier on Wednesday, Iranian media disclosed a "preliminary informal document" regarding the framework of a memorandum of understanding between Iran and the US, covering issues such as the Strait of Hormuz, regional military deployments, and future agreement arrangements. Data released by the American Petroleum Institute (API) showed 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. (Jin10 Data APP)

The minutes of Xingye Silver&Tin's investor briefing announced on May 27 show: 1. Question: Mr. Sun! After the commissioning of Yinman Phase II, the plan is to mainly process lead-zinc-silver series ore, and the ore type and grade are expected to show relatively small changes compared to the Phase I lead-zinc system. Simply put, Zone 1 and Zone 4 are important resource replacement areas for Yinman Mining in the future, but currently they still belong to "potential zones" and cannot be directly classified into the "core rich ore" category like Orebody No. 17. Xingye Silver&Tin's response: Thank you for your attention! As of now, Orebody No. 17 is the main orebody that has been proven at Yinman. 2. Question: Hello, could you share the company's outlook on its own resources going forward and its assessment of the future market? Xingye Silver&Tin's response: Thank you for your attention! As an important participant in China's mineral resources sector and one of the world's leading silver-tin polymetallic mining enterprises, the company is firmly optimistic about its strategic layout, resource reserves, and industry prospects. 3. Question: Mr. Sun, over the past two years, the company has continuously pursued project acquisitions with an expanding financing scale. Can talent and technology be guaranteed? Can timely operations and safety be ensured? Xingye Silver&Tin's response: Thank you for your attention! In recent years, the company has prudently conducted project acquisitions and financing activities centered on its core business, with the overall expansion pace being controllable. Currently, the company has a complete talent pipeline and mature core technologies, and has established a standardized operational management and safety and environmental protection-related controls system, which can fully ensure the stable operation of all acquired projects and effectively prevent various risks. 4. Question: Mr. Sun, was your increase in shareholding in 2026 because you are optimistic about the company's several major projects this year? Xingye Silver&Tin's response: Thank you for your attention! Like other small and medium investors of the company, I am firmly optimistic about the company's potential investment value and plan to hold for the long term. 5. Question: @Director, Vice President and Board Secretary Sun Kai. Dear Secretary Sun, the company's Hong Kong IPO prospectus disclosed a 2026 tin production guidance of 5,500 mt, but Q1 production was only 777 mt, annualized at only 3,100 mt, far below the full-year guidance. May I ask: 1) Was the low Q1 production due to the technological transformation ramp-up of Yinman's copper-tin system, equipment commissioning, or low recovery rates? 2) What is the capacity release pace in subsequent quarters, and can the full-year guidance of 5,500 mt be achieved? 3) What are the timetable for reaching full production after technological transformation and the recovery rate improvement targets? Xingye Silver&Tin's response: Thank you for your attention! Based on the principles of comprehensive resource recovery and safe and efficient mining, the company simultaneously mines Orebody No. 17 and other copper-tin orebodies. For the company's production data, please refer to the periodic reports published on the company's designated information disclosure media. 6. Question: After the acquisition of Weiling Co., the company's related resources will inevitably be tilted toward that company. Please terminate the acquisition of Weiling Co. Xingye Silver&Tin's response: Thank you for your attention! Regarding the progress of the Weiling Co. project, please follow the relevant announcements disclosed by the company on designated media. 7. Question: What are the respective positioning of Xingye Silver&Tin A-shares, Xingye Silver&Tin H-shares, and Weiling Co.? Xingye Silver&Tin's response: Thank you for your attention! Regarding the progress of the Weiling Co. project, please follow the relevant announcements disclosed by the company on designated media. 8. Question: Dear Board Secretary, is the Q1 performance sustainable? What are the current capacity and inventory of silver and tin respectively? Xingye Silver&Tin's response: Thank you for your attention! In Q1 2026, the company's mined silver production was 78.95 mt and mined tin production was 777.33 mt. As of the end of Q1 2026, silver inventory was 15.04 mt and tin inventory was 83.67 mt. 9. Question: Is there a preliminary timetable for the Hong Kong listing? Can it be completed before the end of December this year? Among the company's plans, no projects have been implemented in Xinjiang yet. What kind of resources is the company planning for in the Xinjiang segment? Xingye Silver&Tin's response: Thank you for your attention! The company will release progress announcements on designated media in a timely manner based on project developments. Please stay tuned! 10. Question: Dear Board Secretary, how does the company view the sustained growth in silver and tin demand driven by AI and new energy? Tin production was 8,900 mt in 2024, but the 2026 guidance was lowered to 5,500 mt. What is the core reason? What is the pace of subsequent capacity release for the Yinman technological transformation and the Morocco project? Xingye Silver&Tin's response: Thank you for your attention! The materials related to the Hong Kong listing adopt the JORC Code, a technical standard developed by Australia. For example, the JORC Code defines "ore reserves" as the economically mineable part of measured and/or indicated mineral resources. The above standard differs to some extent from China's standards, resulting in certain deviations between the relevant data under planning and actual production and operations. Specific production data shall be subject to the data disclosed in the company's periodic reports. 11. Question: Has the land certificate and construction permit for Yinman Phase II been obtained? Please do not respond with "please follow the relevant announcements disclosed by the company on designated media." Xingye Silver&Tin's response: Thank you for your attention! Yinman Phase II is expected to commence construction on July 1. After construction begins, the company will promptly disclose relevant progress announcements. Please stay tuned! 12. Question: Last year, the company was bullish on silver prices continuing to rise and chose to stockpile. Now silver prices are under pressure and the company did not hedge. Is the company still bullish on silver?The stock price has been continuously under pressure. Will the company proactively manage this? Xingye Silver&Tin replied: Thank you for your attention! As of now, the company has not conducted any futures hedging business. The company's hedging is carried out prudently at appropriate times based on actual production and operations as well as market conditions, with strict control over transaction risks. 13. Question: What is the current tin recovery rate at Yinman? The report for the Hong Kong listing shows a significant decline in grade. Is this in line with the company's current situation? If based on that report, it seems the company does not need to proceed with the Phase II expansion of Yinman, which appears somewhat contradictory. When will all of the company's capacity reach full production? After all capacity reaches full production, what will be the approximate production of silver and tin? Atlantic Tin has a gold exploration right. Could you briefly introduce the situation of that mine? Does the company have any plans to increase its equity stake in Far East Gold in the future? Xingye Silver&Tin replied: Thank you for your attention! The technical standards used in the Hong Kong listing materials are based on the JORC Code formulated by Australia. For example, the JORC Code defines "Ore Reserves" as the economically mineable part of Measured and/or Indicated Mineral Resources. The above standards differ to some extent from China's standards, resulting in certain deviations between the relevant data in the long-term planning and actual production and operations. Specific production data shall be subject to the data disclosed in the company's periodic reports. 14. Question: Hello, Secretary of the Board. The resource volumes and capacity plans for Yinman and Yubang Mining disclosed in the Hong Kong IPO prospectus are lower than the company's previous communication figures. What is the core reason? Is it due to differences in the JORC Code methodology (only including Measured and Indicated Resources, excluding Inferred Resources)? Does it involve resource reductions, grade downgrades, or mining plan adjustments? Is there room for future resource additions or upward revisions? Xingye Silver&Tin replied: Thank you for your attention! The technical standards used in the Hong Kong listing materials are based on the JORC Code formulated by Australia. For example, the JORC Code defines "Ore Reserves" as the economically mineable part of Measured and/or Indicated Mineral Resources. The above standards differ to some extent from China's standards, resulting in certain deviations between the relevant data in the long-term planning and actual production and operations. Specific production data shall be subject to the data disclosed in the company's periodic reports. 15. Question: Mr. Sun, based on the materials disclosed for the company's Hong Kong listing, the company's production of silver and especially tin is significantly lower than previous expectations. Is this estimate, this guidance, the company's true guidance, or a theoretical guidance made by SRK based on their assessment? Does the company plan to issue a medium and long-term guidance that is in line with the company's actual production plans to clarify these expectations?Otherwise, these expectations may have a significant negative impact on the company and noticeably undermine investor confidence. In fact, this is also unfavorable for the company's listing on international capital markets for financing and further development. Xingye Silver&Tin's response: Thank you for your attention! The Hong Kong listing-related materials adopt the JORC Code established by Australia as the technical standard. For example, the JORC Code defines "Ore Reserves" as the economically mineable part of Measured and/or Indicated Mineral Resources. The above standards differ to some extent from China's standards, resulting in certain deviations between the relevant data in the long-term plan and actual production and operations. Specific production data shall be subject to the data disclosed in the company's periodic reports. 16. Question: Mr. Sun, hello. The prospectus explains that there will be discrepancies between the Competent Person's planned mineral processing production schedule and the enterprise's actual situation. Could Mr. Sun please introduce the production plan for silver and tin from 2028 to 2030? Xingye Silver&Tin's response: Thank you for your attention! The Hong Kong listing-related materials adopt the JORC Code established by Australia as the technical standard. For example, the JORC Code defines "Ore Reserves" as the economically mineable part of Measured and/or Indicated Mineral Resources. The above standards differ to some extent from China's standards, resulting in certain deviations between the relevant data in the long-term plan and actual production and operations. Specific production data shall be subject to the data disclosed in the company's periodic reports. 17. Question: Specifically regarding Yinman Mining: according to SRK's data, there will be significant grade decline in the future. In addition, the feed grade differs considerably from the company's disclosures in the 2025 annual report and previous annual reports. Is it necessary to issue a specific announcement to provide an explanation based on the different mining standards? Xingye Silver&Tin's response: Thank you for your attention! The Hong Kong listing-related materials adopt the JORC Code established by Australia as the technical standard. For example, the JORC Code defines "Ore Reserves" as the economically mineable part of Measured and/or Indicated Mineral Resources. The above standards differ to some extent from China's standards, resulting in certain deviations between the relevant data in the long-term plan and actual production and operations. Specific production data shall be subject to the data disclosed in the company's periodic reports. 18. Question: Have the specific construction commencement dates been confirmed for Yinman Phase II, Yubang Phase II, the Morocco tin mine, and the Budun Yingen mine managed by the controlling shareholder? Could you also provide the commissioning and full production timelines? Thank you. Xingye Silver&Tin's response: Thank you for your attention!

Xingye Silver&Tin's announcement showed that in 2025, the proportion of operating revenue from the company's main mineral products to total operating revenue was as follows: ore-derived silver (2.176 billion yuan, 39.17%), ore-derived tin (1.65 billion yuan, 29.70%), ore-derived zinc (975.87 million yuan, 17.57%), ore-derived lead (220.95 million yuan, 3.98%), ore-derived iron (180.38 million yuan, 3.25%), ore-derived copper (133 million yuan, 2.39%), ore-derived antimony (100.36 million yuan, 1.81%), ore-derived gold (82.34 million yuan, 1.48%), and ore-derived bismuth (16.67 million yuan, 0.30%). Among them, ore-derived tin and ore-derived silver combined accounted for 68.86% of total operating revenue. Regarding the company's main business and key performance drivers, Xingye Silver&Tin stated in its 2025 annual report: The company is a large mining group primarily engaged in the exploration, mining, and ore processing of non-ferrous metals and precious metals. As of the disclosure date of this report, the company had over 20 subsidiaries, of which 8 were operating mining companies, namely Yinman Mining, Qianjinda Mining, Yubang Mining, Rongguan Mining, Xilin Mining, Rongbang Mining, Ruineng Mining, and Bosheng Mining. Atlas Tin SAS under Atlantic Tin was in the construction phase for the Achmmach tin mine. Tanghe Times Mining was in a suspended construction phase, while Yitong Mining and Yunnan Xigui were in the exploration phase. Hainan Fund was primarily engaged in equity investment management; Xingye Gold (Hong Kong) was primarily engaged in metals and mining trading, corporate M&A, and was responsible for expanding markets outside China and acquiring quality mineral resources ex-China; Hainan Guomao and Tianjin Guomao were primarily engaged in non-ferrous metal mineral product sales and partial raw material procurement; Xingye Ruijin was primarily engaged in process research, technology R&D and upgrading in areas such as exploration, mining and processing, and comprehensive tailings recovery and utilization. Tibet Shannan Antimony Gold, Tibet Xinda Mining, and Xing'an League Fuxingtun Mining served as the company's regional resource integration platforms. During the reporting period, the company successfully acquired 85% equity in Yubang Mining. According to data compiled by the Silver Institute as of the end of 2023, Yubang Mining's monomer silver mine ranked first in Asia and fifth globally. This acquisition further strengthened the company's resource advantages and laid a solid resource foundation for sustainable development. Meanwhile, using its subsidiary Xingye Gold (Hong Kong) as the investment vehicle, the company increased investment in mineral resources outside China and successfully acquired 100% equity in Atlantic Tin. This acquisition was an important step in implementing the company's "going global" strategy. According to the classification standards for large-scale tin mines in the "Standards for Classification of Mineral Resource Reserve Scales" (DZ/T 0400-2022), the Achmmach tin mine owned by Atlantic Tin currently amounts to the equivalent of 5 large deposits. Through this integration of tin ore resources outside China, the company further improved its international tin ore layout and also reserved important strategic resources for long-term development. The company's main performance was derived from non-ferrous metal mining and processing operations. During the reporting period, revenue from non-ferrous metal mining and processing accounted for 99.64% of total operating revenue in 2025. Key factors affecting the operating performance of the mining and processing segment included production and sales volumes of major products, market prices, and costs of non-ferrous metal and precious metal mining and processing operations. Regarding the business plan, Xingye Silver&Tin stated in its 2025 annual report: 2026 is the concluding year of the company's "Second Three-Year" plan. The Board of Directors will closely focus on the theme of high-quality development, fully implement established work objectives, continue to deepen the philosophy of "Trust and Collaboration," and make an all-out push to achieve the closing targets of the "Second Three-Year" plan, with emphasis on the following areas of work: 1. Uphold the bottom line of safety and environmental protection. Using 2026 as the "Year of Safety Management Implementation," the company will comprehensively enforce safety responsibilities, consolidate the achievements of the "Year of Collective Safety Vigilance," strengthen risk anticipation and process control, resolutely prevent all types of safety and environmental protection incidents, and achieve safe, steady, green, and low-carbon development. 2.

Reviewing the 2025 price performance of spot silver: the average price of SMM 1# silver (Ag99.99%) on December 31, 2025 was 18,430 yuan/kg, compared with 7,440 yuan/kg on December 31, 2024, representing an increase of 10,990 yuan/kg, or 147.71%. Recently, spot silver prices have been fluctuating. On May 27, the morning quote for SMM 1# silver (Ag99.99%) was 18,654–18,684 yuan/kg, with an average price of 18,669 yuan/kg, up 0.54% from the previous trading day. Compared with the average price of 18,430 yuan/kg on December 31, 2025, the price edged up by 239 yuan/kg, a gain of 1.3%. Regarding the outlook for precious metals, some institutions' views are as follows: FXTM Senior Research Analyst Lukman Otunuga stated: "As hopes for a US-Iran peace deal waver, gold prices have pulled back and are approaching the $4,450 support level. In addition, market expectations for a US Fed rate hike are steadily building amid conflict-driven price pressures, which is also exerting further downward pressure on gold prices." "Ultimately, if more signs emerge that price pressures are rising, it could further reinforce market bets that the US Fed will keep interest rates higher for longer, which would expose gold to greater downside risk." (Jin10 Data APP) CITIC Futures stated: Renewed tensions in US-Iran geopolitics have dampened risk appetite, while rising oil prices have reignited inflation concerns and strengthened market bets on a US Fed rate hike within the year, with multiple factors dragging silver prices lower. On one hand, US economic data still showed resilience, with the latest Chicago Fed National Activity Index for April at 0.14, significantly better than the previous reading of -0.15. The US May Conference Board Consumer Confidence Index and Present Situation Index both pulled back from prior readings, but the confidence index still beat market expectations. Combined with renewed US-Iran tensions pushing oil prices higher and sparking inflation concerns, market pricing for a year-end US Fed rate hike has strengthened. On the other hand, spot silver's fundamental drivers remained weak, with London market silver lease rates running at persistently low levels. In the short term, silver is expected to maintain a fluctuating trend, with overall capital interest still relatively low. Attention should be paid to US-Iran negotiation progress and strait navigation resumption. If US-Iran negotiations progress smoothly, this could drive a short-term silver rebound, but interest rate expectations will continue to suppress the trend. If geopolitical tensions escalate again and push oil prices higher, caution is warranted regarding further medium-term suppression of silver's industrial products elasticity and potential supply disruptions. Over the long term, weakening US dollar credibility, safe-haven demand, and investment demand provide solid support for silver prices. (Jin10 Data APP) A CITIC Securities research report noted that the resilience of the global economy is being tested by the Middle East conflict, with a glimmer of hope for the resumption of navigation through the Strait of Hormuz. The US economy may continue to grow mildly but unevenly this year, the pace of the EU's weak recovery is being delayed, and Japan's private-sector demand will inevitably be disrupted by energy shortages. High oil prices are already pushing up global inflation, with headline inflation rates in Europe and the US likely to fluctuate at highs this year, while Japan's headline inflation rate may continue its mild performance. The US Fed may not cut interest rates at all this year, while potential rate hikes by the ECB and BOJ are imminent, and the "unrestrained" fiscal stance of Japanese and European political circles may constitute a source of market risk this year. We maintain our view that US equities will outperform US bonds and that the US dollar index has support, and gold prices are expected to break free from their predicament as tail risks of inflation dissipate. ANZ analyst Kumar, Soni recently stated that inflation expectations, rising US Treasury yield, and a stronger US dollar are unfavourable factors putting gold prices under pressure. These factors will persist until we can clearly determine how long this conflict will last. Gold has fallen more than 14% since the outbreak of war in late February. OANDA Senior Market Analyst Kelvin Wong stated that since early March, the overall trend of the 10-year US Treasury yield has remained in a medium-term upward phase. Therefore, at this juncture, gold bulls may not be as aggressive in pushing prices higher. Gold is expected to continue weakening over the next few trading days, with resistance at $4,645 and support at $4,456. (Jin10 Data) Goldman Sachs stated that central banks are expected to increase gold purchases, helping gold prices rebound by year-end. Analysts Thomas, Lina and Struyven, Daan stated in a research report published on May 15 that the average monthly central bank gold purchases in 2026 are expected to rise to 60 mt. Based on the revised accumulation model, the 12-month average of central bank gold purchases in March reached 50 mt, compared with a previous figure of 29 mt. Citing internal surveys, the analysts noted that central banks have long-term rigid allocation demand for gold, and recent changes in the geopolitical landscape are likely to continue driving countries to accelerate asset diversification. JPMorgan lowered its 2026 average gold price forecast from $5,708 per ounce to $5,243 per ounce. As demand is expected to re-accelerate in H2 2026, the base case still projects gold prices reaching $6,000/ounce by year-end.

In the first quarter of 2026, global energy storage system shipments reached 100.0 GWh, a 96.5% increase from 50.9 GWh in the same period of 2025, bringing quarterly shipments to an entirely new scale.
