NOAA will now begin preparation of an Environmental Impact Statement for TMC USA's proposed exploration activities. The certification follows NOAA's April 2026 determination that TMC USA's separate consolidated application for an exploration license and commercial recovery permit for the USA A area is fully compliant with the Deep Seabed Hard Mineral Resources Act.

Around May 23, 2026, import and export data for cobalt and lithium battery industry chain-related products in April were released in a concentrated manner. Data showed that China's spodumene imports in April reached 758,000 mt in physical content, down 9.5% MoM and up 21.7% YoY. Lithium carbonate imports, China imported 32,650 mt of lithium carbonate in April, up 9% MoM and up 15% YoY....... SMM compiled the import and export data for battery materials, as detailed below: Upstream Lithium Concentrates In April 2026, China's spodumene imports reached 758,000 mt in physical content, down 9.5% MoM and up 21.7% YoY, equivalent to approximately 63,000 mt of LCE. Customs data showed that April spodumene imports pulled back MoM from March, reaching 758,000 mt in physical content. By source country, Australian ore port arrivals returned to relatively normal levels, with over 350,000 mt arriving this month, up 38.9% MoM; Zimbabwe's earlier shipments arrived in the month at 102,000 mt, down 9.2% MoM; South Africa and Nigeria saw some contraction in monthly port arrivals, while ore from Mali had almost no notable port arrivals this month due to shipping schedule impacts. Notably, spodumene ore powder sold by Brazil in early 2026 arrived at ports this month, driving a significant increase in port arrivals from this country. Additionally, after SMM screening, the month's incoming ore was equivalent to 63,000 mt of LCE. Among the incoming ore, lithium concentrates accounted for 67%, with the share edging down MoM, mainly because apart from Australia , ore from other source countries contained some relatively low-grade ore. Source: China Customs, compiled by SMM Spodumene concentrates (CIF China) spot pricing, according to SMM spot quotes, spot prices for spodumene concentrates (CIF China) fluctuated upward in April. As of April 30, the spot price for spodumene concentrates (CIF China) rose to $2,540/mt, up $221/mt from the month-end March price of $2,313/mt, a gain of 9.81%. According to SMM, lithium carbonate prices continued to rise in April, and spodumene concentrates prices rose in tandem with salt prices, with gains exceeding those of lithium carbonate itself, causing non-integrated enterprises that purchased externally spodumene concentrates to suffer losses, with spot profitability remaining in deficit. In April, spot circulation of lepidolite concentrates relatively eased. Meanwhile, as lithium carbonate prices rose, processing fees for non-integrated enterprises also increased accordingly, preserving a certain profit margin for their processing operations and enabling these enterprises to achieve spot profitability. However, recently, spodumene concentrates prices adjusted in tandem with lithium carbonate price fluctuations, and the price transaction center shifted downward. According to SMM's latest findings, disrupted by rumors of production resumptions at Jiangxi mines this week, lithium carbonate futures and spot prices declined, further dragging down the overall transaction center. Currently, lithium mines showed a weak willingness to make shipments, and transactions were mostly concentrated between traders and buyers. Port lithium ore inventory continued to decline. Going forward, attention should still be paid to the potential tight lithium ore supply triggered by high operating rates in the lithium chemicals industry, and lithium ore prices were expected to hold up well. Lithium Carbonate According to customs data, China imported 32,650 mt of lithium carbonate in April, up 9% MoM and 15% YoY. Of this, 21,000 mt was imported from Chile (65% of total imports), 9,555 mt from Argentina (29%), and 1,100 mt from Indonesia (3%). From January to April, China's cumulative lithium carbonate imports reached 116,000 mt, up 47% YoY cumulatively. In April, China exported 370 mt of lithium carbonate, down 17% MoM and 50% YoY. From January to April, China's cumulative lithium carbonate exports totaled 1,886 mt, up 7% YoY cumulatively. In April, China imported 17,942 mt of lithium sulfate, up 9% MoM and 296% YoY. From January to April, China's cumulative lithium sulfate imports reached 58,900 mt, up 121% YoY cumulatively. According to SMM spot quotes, spot lithium carbonate prices generally trended upward in April. As of April 30, the spot lithium carbonate price rose to 177,000 yuan/mt, up 14,000 yuan/mt or 8.59% from 163,000 yuan/mt on March 31. According to SMM analysis, China's lithium carbonate prices followed a "V-shaped" trend of first declining then rising in April, with the monthly average price up 6% MoM. In the first ten days, geopolitical disruptions in the Middle East intensified global risk-aversion sentiment, causing non-ferrous metals and lithium carbonate prices to fluctuate downward. In the mid-to-late period, driven by Zimbabwe's export ban, Jiangxi mine license renewals, and rising costs, prices began to rebound and fluctuate upward, with the month-end price center shifting notably higher. Upstream and downstream purchasing remained stagnant, with the psychological price spread widening week by week. Upstream producers held prices firm and held back from selling, maintaining high offer prices; downstream buyers made just-in-time procurement only, with psychological price levels concentrated at 155,000-175,000 yuan/mt, restocking on dips only when prices fell rapidly. In April, battery-grade spot lithium carbonate prices dropped to around 155,500 yuan/mt in the first ten days, then rallied all the way to 177,000 yuan/mt by month-end. As of May 29, domestic battery-grade spot lithium carbonate was quoted at 174,000-181,000 yuan/mt, with an average price of 177,500 yuan/mt. Battery Materials LiPF6 According to China Customs data, in April 2026, China's cumulative LiPF6 exports totaled approximately 868 mt, down approximately 80.9% MoM, while cumulative LiPF6 imports were approximately 96 mt. Export side, China's LiPF6 exports in April 2026 were approximately 868 mt, down approximately 80.9% MoM from March and down approximately 33.2% YoY. Specifically, as the VAT rebate policy for LiPF6 exports was officially abolished starting April 1, 2026, enterprises rushed to export in March in advance, and ex-China electrolyte enterprises built up certain inventory, leading to MoM declines in China's exports to multiple major destination countries in April. Among them, exports to Poland were 337.5 mt (down approximately 80.4% MoM), South Korea 81.804 mt (down approximately 92.56% MoM), Czech Republic 150 mt (down approximately 67.43% MoM), and the US 101.908 mt (down approximately 61.7% MoM). Only exports to Japan saw an increase — exports to Japan were 191.37 mt, up approximately 50.77% MoM. Artificial Graphite In April 2026, China's artificial graphite imports were 757 mt, up 12.4% MoM and down 32.9% YoY. Average import price side, in April 2026, the average import price of China's artificial graphite was 75,941 yuan/mt, up 23.1% MoM and up 14.6% YoY. In April 2026, China's artificial graphite exports were 45,895 mt, up 22.3% MoM and down 21% YoY. Average export price side, in April 2026, the average export price of China's artificial graphite was 9,214 yuan/mt, down 6.6% MoM and up 0.26% YoY. Exports from the top five provinces rose 21% MoM from the previous month, with two provinces seeing export growth exceeding 35% MoM and another province achieving a MoM increase of 20%. Import market, downstream power battery enterprise orders in China gradually recovered in April. Combined with tight spot capacity at leading anode enterprises, restocking demand was released, boosting artificial graphite imports to rebound from weakness on a MoM basis. However, import volumes remained on a YoY decline, primarily because China's anode industry had ample overall capacity with supply still in a surplus pattern. Domestic self-sufficiency continued to strengthen, and the industry's reliance on imported raw materials and finished products steadily declined. Flake Graphite In April 2026, China's flake graphite imports were 3,178 mt, down 19% MoM and down 45% YoY. Data source: China Customs, SMM In April 2026, China's flake graphite exports totalled 4,093 mt, down 50% MoM and 54% YoY. Export market, the official cancellation of the flake graphite export tax rebate policy this month directly squeezed the profit margins of foreign trade enterprises, significantly dampening overall export willingness across the market. Meanwhile, the approval pace for flake graphite export licences slowed down, hindering foreign trade shipment processes. Combined with weak ex-China end-use demand, multiple bearish factors converged to directly boost a sharp decline in industry export volumes. The import market also continued to weaken. Goods originally destined for exports were redirected to the domestic sales market, making China's local supply increasingly abundant. Market enthusiasm for import procurement was insufficient, ultimately causing imports to decline in tandem this month. Phosphate Ore May 20, 2026, from customs data. In April 2026, China's phosphate ore imports were 207,000 mt. April imports rose 13.5% from 182,000 mt in March. The total import value in April was $19.741 million, up 35.7% MoM from $14.552 million in March. The average unit price was $95.5/mt, up 19.6% from $79.9/mt in March. Import commentary: In May, Egypt's phosphate ore exports faced "policy tightening and weakening demand". On May 13, Egypt's Ministry of Petroleum and Mineral Resources announced it would no longer sign any new phosphate ore export contracts. Previously, Egyptian Prime Minister Mustafa Madbouly stated clearly at a meeting on May 10 that the government was pushing a transition from raw material exports to the manufacturing of high-value-added products such as phosphate fertiliser. Already signed long-term contracts would not be affected. This is expected to push up import prices and may affect import volumes going forward. Cobalt Cobalt Hydrometallurgy Intermediate Products In April 2026, China's cobalt hydrometallurgy intermediate products imports were approximately 1,247 mt in physical content, down 26% MoM and 98% YoY. Of this, imports from the DRC were approximately 945 mt in physical content, down 43% MoM and 98% YoY. In April 2026, the average import price of China's cobalt hydrometallurgy intermediate products was $17,187/mt in physical content, up 2.63% MoM. It was reported that most miners had completed Q4 2025 quota approvals, but Q1 2026 quota approvals were again delayed due to issues with sampling, detection, and other procedural processes, resulting in lower approval efficiency. Additionally, DRC currently faced tight transportation capacity. For economic reasons, fleets prioritized transporting oil products and chemicals that were in short supply for production, followed by other metals with shorter turnover cycles, and cobalt among non-ferrous metals came last, meaning cobalt transportation capacity faced significant challenges. Constrained by the above factors, miners primarily focused on building in-transit inventory and had not yet concentrated on booking vessels, so the timing of large-scale intermediate product arrivals at ports was likely to continue being delayed. Unwrought Cobalt China's unwrought cobalt imports in April 2026 were approximately 1,334 mt, up 39% MoM and up 59% YoY. In April, refined cobalt imports mainly came from Indonesia, Russia, and Madagascar, with imports of 462 mt, 457 mt, and 182 mt respectively. The main reason for the increase this month was that domestic smelters lacked intermediate product raw materials and imported cobalt slabs and cobalt briquettes for re-dissolution to ensure normal production. In terms of average import prices, the average import price of unwrought cobalt in China in April 2026 was $52,724/mt, up 4.72% MoM. Cumulative imports from January to April 2026 totaled 5,916 mt, up 153% YoY cumulatively. Export side, China's unwrought cobalt exports in April 2026 were approximately 218 mt, down 47% MoM and down 95% YoY. By country, China's exports to the US dropped significantly, with April exports to the US at 35 mt, down 87.5% MoM. The main reason was that US alloy-grade refined cobalt demand pulled back in April, and ex-China branded refined cobalt was already sufficient to meet regional demand, with some refined cobalt traders redirecting destinations from the US back to China. In terms of average export prices, the average export price of unwrought cobalt in China in April 2026 was $54,590/mt, up 5.80% MoM. Cumulative exports from January to April 2026 totaled 1,792 mt, down 76% YoY cumulatively.

[SMM Aluminum Express News] Ministry of Energy and Mineral Resources of Indonesia is investigating seven illegal mining cases across Indonesia with estimated potential state losses of IDR 857.55 billion. According to the ministry, the cases involve both mining without permits (IUP) and operations conducted outside approved concession areas (WIUP), with investigations spanning regions including Kalimantan, Sumatra, Java, and Maluku.

Tongguan Mine Construction announced that it recently received a bid-winning notification from Xingyao Icarus Limited, winning the bid for the mine construction and mining engineering of the Cuia-Mavoio copper mine in Uíge Province, Angola, with a contract value of approximately $230 million. The infrastructure construction period is 18 months, and the production period is 60 months.

Exploration began in 2010, with the first production phase targeting open-pit ore processing of 2,500 mt per day and a total mining capacity of 4,000 mt/day; the underground mine plans to commence in H2 2026.

The investor relations activity record of Yunnan Copper for May 26–27, 2026 shows: 1 What is the company's planned copper concentrate production from captive mines this year, and what is the approximate cost level of the mining enterprises? According to the company's 2026 financial budget and production plan, full-year self-produced copper concentrates are expected to contain 69,800 mt of copper metal content. The company's current mining enterprises mainly include Diqing Nonferrous, Liangshan Mining, Yuxi Mining, and Diqing Mining. Due to differences in resource endowment and the life cycle stage of each mine, cost levels vary, with Diqing Nonferrous, Liangshan Mining, and Yuxi Mining having relatively lower costs. Meanwhile, the company strives to maintain overall cost stability through measures such as lean operations and increasing mining volumes. 2 What is the progress of the Hongnipo copper mine construction project of Liangshan Mining? The Hongnipo copper mine is currently under construction, with cumulative verified resource reserves of 16.06 million mt of ore, an average copper grade of 1.42%, and copper metal content of 592,900 mt. The project is progressing in an orderly manner as planned and is expected to be completed and ready for commissioning in 2026. 3 Will the mine resources under the company's major shareholder be injected into the publicly listed firm? Asset injection involves complex systematic work that requires comprehensive consideration of development strategy, asset conditions, regulatory requirements, and shareholder interests. The company will continue to focus on and strive to enhance the quality of the publicly listed firm, and if there are any new relevant arrangements, it will strictly follow prescribed decision-making and disclosure procedures. 4 Has the company set a target for resource self-sufficiency rate? The company regards improving resource self-sufficiency rate as an important long-term strategic task, relying primarily on three paths: commissioning of projects under construction, tapping potential of existing mines, and external resource acquisitions. Regarding projects under construction, the company successfully completed the acquisition of 40% equity in Liangshan Mining in December 2025, and the Hongnipo project is expected to be completed and ready for commissioning in 2026. Regarding tapping potential of existing mines, the company leverages its major mines to continuously intensify deep and peripheral exploration efforts, steadily advancing resource succession and reserve additions. Regarding external resource acquisitions, while managing existing mines and smelters well, the company actively monitors quality mineral resource projects and prudently conducts field trips and evaluations based on strategic positioning and market demand. 5 What proportion can the company's copper smelting TC long-term contracts approximately reach? The company follows the principles of marketization and maximization of comprehensive benefits in externally purchasing raw materials. As one of the larger copper concentrate purchasers in China, the company has long maintained good, stable, long-term cooperative relationships with major suppliers, and actively negotiates with copper concentrate suppliers to stabilize long-term contract supply and ensure orderly production. 6 What were the company's sulphuric acid selling price and production in Q1 2026? According to the company's 2026 production plan, planned annual sulphuric acid production is 5.76 million mt. In Q1 2026, sulphuric acid production progressed in an orderly manner as planned. Price side, as a by-product of copper smelting, sulphuric acid selling prices are influenced by multiple factors including regional market supply and demand, transportation conditions, and industry prosperity. Since the beginning of this year, driven by robust downstream demand and tight supply in some producing areas, sulphuric acid selling prices have stayed high. The company seized market opportunities, reasonably arranged production and sales, and made positive contributions to operating performance. Meanwhile, the company will continue to monitor price changes and dynamically optimize production and sales pace. 7 Does the company have further cost reduction plans? The company's mining and smelting enterprises continuously pursue lean cost reduction to build low-cost competitive advantages. For example, the company is comprehensively advancing the "Three-Year Cost Reduction 3.0" initiative, continuously promoting cost reduction and efficiency improvement, and lowering unit production costs through technological upgrades, process optimization, and improved management efficiency. 8 What major capital expenditures are expected in the future? The company's future major capital expenditures will primarily focus on the following strategic directions: first, resource acquisition—continuously strengthening exploration and acquisition of quality copper mineral resources in and outside China to enhance resource security capabilities; second, intelligent manufacturing—advancing automation, digitalization, and intelligent upgrades of mines and smelting plants to improve production efficiency and safety levels; third, green and low-carbon development—increasing investment in environmental protection, energy conservation, and other areas to promote sustainable development. Performance side: Yunnan Copper's Q1 2026 report disclosed on April 24 showed that the company achieved total operating revenue of 52.959 billion yuan, up 49.62% YoY; net profit attributable to the parent was 675 million yuan, up 7.93% YoY. Regarding the reasons for the increase in operating revenue, Yunnan Copper stated that it was mainly due to higher product prices compared to the same period last year and increased sales volumes compared to the same period last year. Yunnan Copper's 2025 annual report showed that in 2025, the company firmly established market entity awareness, strengthened its lean operations system, and solidly carried out production organization, cost control, indicator optimization, marketing value creation, and other work, with main product production reaching record highs and key technical and economic indicators continuously optimized. Full-year production included copper cathode of 1.6411 million mt, gold of 26.04 mt, silver of 735.38 mt, and sulphuric acid of 6.189 million mt, with copper cathode, gold, and silver production all reaching record highs. Full-year operating revenue reached 79.542 billion yuan and net profit attributable to the parent was 1.301 billion yuan, with operating efficiency steadily improving. Cost and technical indicators were continuously optimized, with mine concentrate copper content and smelting copper cathode unit full cost outperforming annual cost reduction targets. Key technical indicators for smelting and mining remained stable with improvement. In 2025, the copper smelting total recovery rate exceeded the target by 0.07 percentage points, and slag flotation tailings copper content was optimized by 0.01 percentage points versus the target, both reaching industry-leading levels. Yunnan Copper announced that in 2025, the company's concentrate copper content production, on a consolidated statement basis, was 69,400 mt, up 26.64% YoY from 2024, mainly because the company issued shares to acquire 40% equity in Liangshan Mining held by Yunnan Copper Group during 2025, and Liangshan Mining was included in the consolidated statements as of December 31, 2025, with its full-year production included in the statistics. Regarding the company's main businesses, Yunnan Copper introduced in its 2025 annual report: The company's main businesses cover copper exploration, mining and beneficiation, smelting, extraction of precious metals and rare scattered metals, sulphur chemicals, and trading. It is an important copper, gold, silver, and sulphur chemical production site in China. The company has established a relatively complete industry chain in copper and related nonferrous metals and is a copper enterprise with deep industry heritage. Main products include copper cathode, gold, silver, industrial sulphuric acid, and rare and scattered metal products such as molybdenum, platinum, palladium, selenium, and tellurium. The company's main products are all produced according to international standardization organization standards, operating effectively under the international ISO9001 quality management system to ensure strict quality control. The company's main product, copper cathode, is widely used in electrical, light industry, machinery manufacturing, construction, national defense, and other fields; gold and silver are used in finance, jewelry, electronic materials, etc.; industrial sulphuric acid is used as raw material for chemical products and in other sectors of the national economy. The company's "Tiefeng" brand copper cathode is registered on the Shanghai Futures Exchange and the London Metal Exchange; "Tiefeng" brand gold is registered on the Shanghai Gold Exchange (SGE) and the Shanghai Futures Exchange; "Tiefeng" brand silver is registered on the Shanghai Gold Exchange (SGE), the Shanghai Futures Exchange, and the London Bullion Market Association. Regarding the company's future development outlook, Yunnan Copper introduced in its 2025 annual report: Yunnan Copper adheres to the guidance of Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era, fully implements the spirit of the 20th National Congress of the Communist Party of China and its successive plenary sessions, and upholds and strengthens the Party's overall leadership. The company actively serves major national strategies, adheres to promoting high-quality development as the theme, fully, accurately, and comprehensively implements the new development philosophy, continuously enhances core functions and improves core competitiveness, and better plays its role in scientific and technological innovation, industrial control, and security support in building a modern industrial system and constructing a new development pattern. The company emphasizes "two guarantees" (important mineral resource guarantee and important metal material guarantee), "two innovations" (scientific and technological innovation and management innovation), "two constructions" (strengthening Party building, especially cadre team building), and "three unwavering commitments" (unwavering in accelerating structural adjustment, unwavering in deepening enterprise reform, and unwavering in international operations and increasing "going global" efforts). The company focuses on "digital-intelligent transformation, expanding resources, refining mines, optimizing smelting, solidifying recycled (copper), and detailing rare scattered (metals)," accelerating the construction of a world-class excellent copper company, and continuously opening new prospects for Yunnan Copper's high-quality development. Guosen Securities' research report commenting on Yunnan Copper on April 11 showed: Quality asset consolidation. Production side, the company's copper ore production was close to 70,000 mt, with major mines maintaining stable production. Copper smelting side, after Southwest Copper reached full production, the company's 2025 copper cathode production was 1.64 million mt, up 440,000 mt or 36% YoY. During the reporting period, the company purchased 40% equity in Liangshan Mining through share issuance to its major shareholder, achieving consolidation. Liangshan Mining is a quality asset, with its mines featuring open-pit mining, abundant reserves, higher grade than the publicly listed firm's existing copper mines, and lower costs than the publicly listed firm's existing copper mines. In H2 2025, profitability of major subsidiaries generally declined. Although copper, gold, and silver prices rose significantly in H2 2025, the company's mining operations saw profit decline QoQ. Smelting operations also declined significantly in H2 2025, which was related to the sharp drop in copper concentrate TCs. As sulphuric acid prices are expected to stay high, the company's smelting business profitability is expected to improve. Gross profit by product side, the company produces over 6 million mt of sulphuric acid annually. Benefiting from sulphuric acid price increases, sulphuric acid business gross profit in 2025 was 2.03 billion yuan, up 1.5 billion yuan YoY, representing a performance highlight. Since early 2026, sulphuric acid prices have continued to rise, and this is expected to further boost earnings. Leveraging the copper industry's high-prosperity cycle in recent years, the company's asset quality has improved, and during the reporting period it achieved consolidation of Liangshan Mining, a quality asset. As the sole copper publicly listed platform under Chalco Group, injection of other quality assets from the major shareholder is anticipated. Although the copper smelting business is under pressure in the short term, the government has issued policies to strictly control new copper smelting capacity, and the company benefits from global copper smelting capacity rationalization, with a favorable long-term industry landscape. Maintain "Outperform" rating.

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.

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.

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! Yinman Phase II is expected to commence construction on July 1; the Yubang 8.25 million mt/year project is expected to commence construction in Q3; the Atlantic Tin project has obtained all construction permits and is currently carrying out preliminary preparation work including contractor tender and equipment transportation, with construction expected to commence in mid-July; all the above projects are expected to achieve commissioning with feed materials in Q4 2028. The managed company Budun Yingen plans to commence construction in Q4, with production expected to begin in 2029. 19. Question: Director Sun, in a previous institutional survey, you clearly stated that the company's quarterly tin production of 3,600 mt can be achieved on a regular basis. Is there an opportunity to achieve this quarterly target this year? Xingye Silver&Tin's response: Thank you for your attention! Adhering to the principles of comprehensive resource recovery and safe, 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 by the company on designated information disclosure media. 20. Question: Does the company have the right to abandon the acquisition of the relevant equity in Weiling Shares? Xingye Silver&Tin's response: Thank you for your attention! For the progress of the Weiling Shares project, please refer to the relevant announcements disclosed by the company on designated media. 21. Question: Director Sun, in the records of a previous institutional survey, the company responded that Yinman's quarterly tin production of 3,600 mt can be achieved on a regular basis, but it seems this has not been realized subsequently. Is there a possibility of attempting to reach this record this year? Xingye Silver&Tin's response: Thank you for your attention! Adhering to the principles of comprehensive resource recovery and safe, 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 by the company on designated information disclosure media. 22.

Question: After acquiring Weiling Shares, our company will become an AAH (Xingye Weiling H) publicly listed firm. What is the company's positioning for the three listing platforms? Xingye Silver&Tin's response: Thank you for your attention! For the progress of the Weiling Shares project, please refer to the relevant announcements disclosed by the company on designated media. 26. Question: In the company's 2025 annual report, the company stated "solidly advancing the subsequent acquisition and integration of Weiling Shares," but Weiling Shares has been subject to a delisting risk warning. What is the purpose of our acquisition of Weiling? Xingye Silver&Tin's response: Thank you for your attention!For updates on the progress of Weiling shares project, please refer to the relevant announcements disclosed by the company on designated media.

Among them, ore-derived tin and ore-derived silver combined accounted for 77.19% of total operating revenue. Xingye Silver&Tin's Q1 report stated that operating profit for the current period increased 238.16% compared with the previous period, total profit increased 236.36%, and net profit attributable to the parent company's shareholders increased 257.32%. The main reasons were: During the reporting period, the selling prices of the company's main mineral products such as silver and tin rose YoY; Yubang Mining's capacity was gradually released, with ore-derived silver production and sales increasing significantly YoY; and the transfer of 60% equity in Shuangyuan Non-ferrous realized investment income of 321 million yuan. Xingye Silver&Tin's 2025 annual report showed that in 2025, the company achieved operating revenue of 5.555 billion yuan, up 30.09% YoY; total profit of 2.096 billion yuan, up 18.75% YoY; and net profit attributable to shareholders of the publicly listed firm of 1.704 billion yuan, up 11.40% YoY. 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. Advance key project construction at full speed, strengthen full-process management of project budgets, schedules, and quality, and coordinate the implementation of projects including the 2.97 million mt expansion of Yinman Mining, the 8.25 million mt expansion of Yubang Mining, the Morocco project, and the Budun Yingen Mining (under trusteeship) project, ensuring on-schedule completion, reaching full production, and releasing capacity benefits. 3. Continue to intensify exploration and reserve expansion efforts, properly balance production operations with geological exploration, steadily advance exploration of existing mines and surrounding areas, accelerate the conversion and upgrading of resource volumes, and continuously strengthen the resource foundation. 4. Deepen industrial synergy and resource integration. Leveraging the core regional advantages in Inner Mongolia, the company will steadily expand its resource layout outside China; adhering to silver and tin as the main business direction, it will enrich and optimize resource varieties. The company will solidly advance the subsequent acquisition and integration of Weiling shares, actively track quality mineral project opportunities in and outside China, and enhance overall competitiveness through synergistic industrial M&A. 5. Further strengthen institutional enforcement and internal control management, drive the effective implementation of various systems, processes, and control requirements, and enhance the company's refined management capabilities; strengthen enforcement capacity building to ensure production plans, comprehensive budgets, and various work deployments are fully implemented, and promote deep integration of corporate culture with business management. 6. Advance Hong Kong stock listing preparations at full speed, accelerate the establishment of a dual capital market platform at home and abroad, enhance cross-border capital operation capabilities, provide stronger financial support for the company's resource integration and strategy implementation, and drive the company's high-quality sustainable development to new heights. 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.
