Time flies as the midpoint of 2026 approaches. The zinc concentrate market has witnessed another extraordinary price cycle this year. As of June 12, domestic zinc concentrate treatment charges (TCs) plunged to -50 yuan per metric ton of zinc metal, marking the arrival of negative TCs. Meanwhile, TCs for imported zinc concentrate tumbled to -71.2 US dollars per dry metric ton, both hitting all-time record lows.

From June 3 to June 5, Indonesia Critical Minerals 2026 was held at the Pullman Jakarta Central Park in Jakarta, Indonesia. The conference was organized by Shanghai Metals Market (SMM) and co-organized by the Indonesia Nickel Miners Association (APNI) , the Ministry of Foreign Affairs of the Republic of Indonesia , the National Economic Council of Indonesia , and MMR , in a strategic partnership with the Jakarta Futures Exchange . The conference featured six dedicated forums: the main forum, the nickel and cobalt forum, the tin forum, the coal & energy transition forum, the aluminum forum, and dedicated sub-forums, attracting 3,500+ attendees from 45 countries and regions worldwide, featuring more than 120+ speakers sharing insights on market prices, supply-demand patterns, industry policies, low-carbon development, and ESG development, etc. Conference Background of Tin Forum In 2022, both LME and SHFE tin annual prices closed lower, and the market at the time may not have anticipated that this would serve as the prelude to a three-year upward cycle. From 2023 to 2025, tin prices recorded three consecutive years of gains, with both LME and SHFE tin surging over 30% in 2025. Entering 2026, the upward trend has continued, with tin prices hitting a new record high and becoming one of the most closely watched metals in the industrial metals market. However, this rally has not been smooth. In the past two years, tin prices have fluctuated significantly within an upward channel, driven by deep adjustments in global supply-demand patterns, especially multiple disruptions on the supply side. On the demand side, emerging sectors such as AI servers, PV welding strips, and NEVs have rapidly risen, coupled with a recovery in consumer electronics, continuously highlighting tin's strategic value in high-end manufacturing and steadily expanding rigid demand. On the supply side, global tin resources are highly concentrated, production resumptions in Myanmar have fallen short of expectations, some ex-China mining areas have been disrupted by geopolitical factors, and Indonesia—a key link in global refined tin supply—has seen its industrial policy adjustments become a critical variable affecting market expectations. Reviewing Indonesia's tin industry policy, the past two years have shown a clear trajectory of "standardizing and regulating, tightening exports, and promoting downstream development." In 2024, the Mining Work Plan (RKAB) was adjusted from an annual to a three-year basis, and exports experienced temporary fluctuations during the policy transition. In 2025, Indonesia further strengthened governance over illegal mining, shutting down some illegal tin mines, cracking down on smuggling activities, and adjusting tin ore royalty fees, leading to higher production costs. Entering 2026, the policy direction has become clearer, with studies on restricting refined tin exports, lowering export quotas, and plans to raise tin royalty tax rates, promoting the transition from resource exports to high value-added processing. These adjustments are reshaping the rhythm and trade patterns of the global tin supply chain. As an important platform connecting the global tin industry chain with the Indonesian resource market, the Tin Forum focuses on the latest developments in Indonesia's tin policies, the evolution of the global tin supply-demand pattern, price trend analysis, and industrial cooperation opportunities. It brings together government officials, industry experts, miners, smelters, and downstream end-user representatives to jointly explore new opportunities in the global supply chain amid the transformation of Indonesia's tin industry.

Miller Esq, Strategic & Defense Metals Specialist/Director, Mission Critical Metals, Mission Critical Metals Keynote Speech: The Development Trend of the Tin Market in China Speaker: Zheyu Zhang, Tin Market Analyst, Marketing Department, Yuntin (Honghe) Investment Development Co., Ltd. Keynote Speech: Opportunities and Challenges for Smelters Under Indonesia's New Tin Industry Policies Speaker: Yazid Kanca Surya, Chief Executive Officer, Jakarta Futures Exchange Fragmented Global Supply Chain System Reshaping of the Geopolitical Landscape : Trade disputes and geopolitical tensions are profoundly altering traditional commodity trade patterns. Industrial Security :Countries are increasingly prioritizing long-term stable supply of strategic resources over short-term price advantages. Focus on Critical Minerals : Tin’s industry role is no longer isolated; it has become a core issue in the global energy transition and high-end manufacturing sectors. Evolution of the Tin Market The industry is entering a new phase where credibility is as important as capacity. Promoting Downstream Industrialisation (Hilirisasi) •Historical Development Background: Indonesia has long been dominated by the supply of primary processed products, with most downstream value addition achieved outside China. • Strategic Goals : Indonesia is adjusting export policies, trade management, and supply chain oversight to retain high-value-added industries within the country. Strengthening regulation and cracking down on illegal mining are not punitive measures, but rather efforts to build a transparent system to help the local area vigorously promote the development of downstream industries. Smelters Under Pressure Upstream uncertainties: Illegal mining disrupts the market, raw material supply fluctuates, and price trends are difficult to predict. Downstream market requirements: Strict compliance standards, full transparency in raw material traceability, and continuously rising screening thresholds for buyers. Market Volatility Intensifies The uncertainty in the current operating environment has increased significantly. Enterprises must not only cope with production risks, but also simultaneously address the multiple pressures arising from external shocks and rising operating costs. Investment Barriers in Deep Processing Keynote Speech: Deepening Downstream Diversification, Joining Hands to Foster Long-term Prosperity Guest Speaker: HARRY BUDI SIDHARTA, S.T, MM., Vice President Director, PT Timah (Persero) Tbk Keynote Speech: Challenges and Opportunities for China's Tin Industry amid Global Tin Ore Supply Changes Guest Speaker: Huanbo Qin, Market Analyst, International Tin Association China Keynote Speech: Analysis of Global Tin Price Trends and Future Outlook Speaker: Vicky Qiao, Senior Analyst, Shanghai Metals Market Price Trend Overview Price Review: Amid macroeconomic and geopolitical disruptions, market fundamentals have provided structural support Key Points: Tight mine-side supply has established a long-term price floor, while macro liquidity has primarily driven price fluctuations. Tin Resources and Mine Supply Landscape Supply elasticity is limited, accompanied by a high geographic concentration of reserves; the global static mine life is less than 15 years. Rising mine production alongside shrinking global resources has accelerated reserve depletion in producing countries. DRC: Output from major mines remained stable; however, M23 militant activities increased market uncertainty. ►Risks 1. The M23 armed conflict has spread to the Masisi region east of the Bisie mine and the Goma border crossing between the DRC and Rwanda, directly disrupting the original tin ore transportation route via Goma to Dar es Salaam. 2. To mitigate conflict risks, security at the Bisie mine has been reinforced, and freight routes have been adjusted northward to reroute through Uganda, ultimately destined for the port of Mombasa in Kenya. Nevertheless, market concerns persist that further spread of the M23 conflict could disrupt normal production operations at the mine. 3. The DRC recently experienced an Ebola outbreak, with confirmed cases concentrated in Beni and Bunia, areas adjacent to Uganda. Strict disease prevention measures have been implemented at both the mine and along transportation links; Bisie's mining and freight activities have yet to be affected by the pandemic impact. However, the market remains apprehensive about the local mineral supply outlook. Myanmar's Man Maw Tin Mine: Production Resumptions Hindered • 90% of Myanmar's tin ore production is concentrated in Wa State. To ensure rational resource extraction and stable regional development, Wa State suspended all tin ore mining starting in 2023, with new mining permits only reissued in July 2025. Due to the local rainy climate, the mine pits accumulated significant water during the suspension, making drainage the primary challenge upon work resumption. As the water accumulation issue affected multiple pits, the cost-sharing arrangements for drainage among mining enterprises were long delayed and never finalized. The resulting obstruction of drainage work has directly constrained the mine's production resumption progress. •In February 2026, the local government issued detailed rules clarifying the cost-sharing standards for drainage, and the Wa State tin mine immediately began resuming production. •Currently, strict approval and control of civilian explosives in Myanmar, compounded by disruptions to mining and logistics caused by the rainy season, have led to progress in local production resumptions falling short of expectations. Full resumption is expected only by 2027. The number of new tin mine projects globally is scarce, with generally low ore grades and lengthy development-to-production cycles. New projects generally have low ore grades, posing upside risks to future mining costs and increasing operational difficulty. Only three new projects have grades above 1%. Lower ore grades mean that more raw ore must be processed to produce the same amount of tin metal. The future supply landscape will be markedly differentiated, with total planned and under-construction projects reaching 173.5 kt in capacity, and just four major projects accounting for over 67%. Global supply will be highly dependent on these core mine projects, while five new projects in Australia can only bring a small incremental increase with limited impact. Global Tin Ingot Supply The high concentration of primary tin smelting capacity limits the global supply elasticity of tin ingots. Keynote Speech: Achieving the Trading and Risk Hedging of Pure Tin Ingots Through the Standardized Trading Mechanism of the Futures Market – Commodity Futures Trading Regulatory Authority Guest Speaker: Ima Siti Fatimah, Head of the Commodity Futures Trading Development Bureau, Ministry of Trade of the Republic of Indonesia Keynote Speech: Under the Drive of Geopolitical Policies: Global Strategic Metal Tin Trade Restructuring, Breakthroughs in North American Secondary Production, and New Logic in Solder Consumption Guest Speaker: Joseph G. Miller Esq, Strategic & Defense Metals Specialist/Director, Mission Critical Metals, Mission Critical Metals ► Securing Supply: US Plan to Reshore Critical Metal (Tin) Capacity • Lessons drawn from COVID-19 and World War II. • No primary tin capacity currently exists in North America: no tin ore mining operations, no tin ore smelting capacity. • The US secondary tin market is regionally fragmented. • The US government supports the Nathan Trotter primary/secondary tin smelter. • The Trump administration has made multiple investments in the critical metals sector. • Security situation in the DRC and surrounding regions. ► Data Center Tin Consumption Estimates How much tin is consumed per gigawatt of installed data center capacity? • Servers, GPUs, network systems: 500–1,500 mt. • Power systems, switchgear: 100–400 mt. • Control devices, communication equipment, cooling systems: 50–200 mt. • Tin usage per gigawatt of installed AI data center capacity is approximately 1,200–1,500 mt. Additionally, the speaker noted: the PV industry's annual tin consumption is about 25,000 mt, with average annual new installations of around 30 GW, corresponding to tin demand of 36,000–45,000 mt. Keynote Speech: Due Diligence in the Indonesian Tin Sector: A Tradition of Early Adoption and Pathways for ESG Leadership Guest Speaker: Josue Ruiz, Director of Facility Engagement, Responsible Minerals Initiative Keynote Speech: Malaysian Tin Mine: Market Breakthrough and Global Expansion from the Perspective of Critical Minerals Guest Speaker: DATO DEREK TENG, Director of the SETARA JELITA SDN BHD, President of the MALAYSIA MARITIME SILK ROUTE RESEARCH SOCIETY Critical Minerals in the New Era Strategic Positioning and Core Applications of Tin National Strategic Cornerstone: Listed in the “Critical Minerals List” by many countries, it holds an irreplaceable core position in securing national resource security and maintaining the resilience of global supply chains. Modern Industrial Lifeline: The core raw material for electronic solder manufacturing, it supports semiconductor packaging, PCB circuit boards, and other electronic information industries, serving as the “industrial monosodium glutamate” of modern manufacturing. Frontier Technology Engine: Empowering emerging technologies such as 5G communications, NEV batteries, PV modules, and AI chips, it drives the dual transformation of the digital economy and green transition. Tin: The “Industrial MSG” Driving High-Tech Industries ► A Core Member of the Global Critical Minerals System U.S. Official Designation: According to the U.S. Geological Survey (USGS) “2025 Critical Minerals List,” tin is formally listed as a critical mineral, regarded as a strategic resource vital to national economic development and national security. Global Industry Consensus: In the mineral assessment systems of the EU and other developed economies, tin also occupies a core position. It is an indispensable “emerging cornerstone mineral” supporting the global digital economic transformation and the upgrade of the new energy industry. The global tin application structure in 2025 is very clear: 53% is used in semiconductors and high-end electronic solder, 16% in fine tin chemical new materials, 11% in food-grade tinplate and tin cans, and 8% directly in the PV green new energy industry. Tin Applications in High-Growth Sectors Currently, three major high-growth tracks worldwide are continuously driving rigid incremental demand for tin. First, AI computing power and hyperscale data centers: The tin consumption per unit of high-end AI servers is 3–13 times that of ordinary servers. With the explosive growth of global AI computing power demand, the demand for high-end solder will continue to grow rapidly. Second, new energy vehicles: Tin consumption per vehicle is about three times that of internal combustion engine vehicles, and for intelligent car models, it can reach up to 1.5 kg per vehicle. Third, advanced packaging: The solder ball usage of advanced packaging technologies such as HBM (High Bandwidth Memory) is more than five times that of traditional DRAM. Malaysia at a Crossroads The Decline of a Former Empire and Opportunities for Transformation ► Glorious History · Tin Empire: In the 1960s, Malaysia was the world's veritable "Tin Empire." Its tin production once accounted for one-third of the global total, and revenue from tin exports represented as much as 60% of the country's total export revenue, dominating the global tin trade landscape. ► Current Situation · Dual Challenges: However, after industrial iteration, its share of global production was only 0.2% in 2023, with annual output falling to 6,100 mt, marking a sharp decline. Malaysia still holds considerable secondary resource reserves of 780,000 tonnes, with native ore depleted but tailings holding significant potential. ► Future · Reshaping Value Strategic Empowerment: Leverage the new strategic identity of “critical minerals” to enhance discourse power and bargaining power in the international supply chain. Industrial Leap: Shift away from dependence on primary tin ingot exports and move towards high value-added deep processing manufacturing and the establishment of a circular economy system. Core Challenges Faced Currently, Malaysia’s tin industry faces four core structural challenges. Market Breakthrough: Reshaping Value Embrace the New Identity and Extend into Downstream High Value-Added Sectors Build a Regional Circular Economy Center Core Strategy: Fully leverage Malaysia’s industrial advantage as a global electronics manufacturing center, turning the large amount of tin-containing scrap generated during production—including solder dross, waste circuit boards, etc.—into valuable recycled tin resources, and establish an “urban mining” resource recycling system.

Mine decarbonization cannot be achieved solely through carbon disclosure, carbon offsets, or green procurement. Daily production activities such as transportation and turnaround, captive power supply, crushing and grinding, mine ventilation, and process electricity are the core carriers of carbon emissions. The core challenge for the industry today is to steadily reduce carbon emission intensity against a backdrop of growing demand for minerals. This requires a systematic restructuring of the mine’s overall energy system, rather than simply replacing fuels for individual equipment. Diesel-powered transport is the key battleground for carbon reduction in mines Various types of mobile equipment are the key targets for carbon emission monitoring. The average annual fuel consumption of a single mining truck is close to one million liters. For open-pit mines, fuel consumption is closely linked to haul distance, road gradient, payload, dispatch management, and vehicle idling. Therefore, the transport phase becomes the optimal breakthrough point that balances carbon reduction and production efficiency. The electrification of mining trucks is not a technical bottleneck; the real key lies in whether the supporting core infrastructure, such as charging and energy storage, can enable the equipment to operate at full capacity and ensure that production is not affected. The global fleet of large mining haul trucks numbers about 28,000 units, and is still predominantly diesel-powered. According to RMI estimates, the average annual diesel consumption of a single truck reaches 900,000 liters; energy consumption by haul vehicles accounts for 30%–50% of total mine energy use, corresponding to annual CO2 emissions from the global fleet of approximately 68 million mt.

[Tungsten News Flash] SMM June 5: On May 29 local time, the DRC Council of Ministers reviewed and approved a special decree, officially incorporating six mineral categories—lithium, tantalum, niobium, tungsten, uranium, and rare earths—into the national strategic minerals list. According to the relevant provisions of the DRC's current Mining Code, strategic minerals are subject to a royalty rate of 10%, while the base royalty rate for ordinary non-ferrous metals is 3.5%. After the new policy takes effect, the royalty costs for local mining enterprises involved in newly designated strategic minerals such as lithium and tungsten will increase to nearly three times the original level. This expansion of the catalog is a significant implementation measure by the country to optimize critical minerals revenue distribution and strengthen control over domestic strategic resources. The policy will be officially implemented through a cabinet enforcement decree.

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. 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! 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: Is there a plan to spin off minor metals other than silver and tin to 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. 23. Question: Has the matter of acquiring Weiling been terminated? 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. 24. Question: Has the company already dispatched personnel to take over the production and operations of Jiayu Mining? 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. 25. 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. Xingye Silver&Tin's Q1 report showed that from January to March 2026, the company achieved operating revenue of 2.13 billion yuan, up 85.32% YoY; net profit attributable to shareholders of the publicly listed firm was 1.338 billion yuan, up 257.32% YoY. As of March 31, 2026, the company's total assets were 19.689 billion yuan, and net assets attributable to shareholders of the publicly listed firm were 10.825 billion yuan. Operating revenue breakdown: From January to March 2026, the proportion of operating revenue from the company's main mineral products to total operating revenue was as follows: ore-derived silver (1.41 billion yuan, 66.21%), ore-derived tin (234 million yuan, 10.99%), ore-derived zinc (228.12 million yuan, 10.71%), ore-derived lead (71.85 million yuan, 3.37%), ore-derived antimony (53.1 million yuan, 2.49%), ore-derived gold (51.02 million yuan, 2.40%), ore-derived iron (44.17 million yuan, 2.07%), ore-derived copper (35.65 million yuan, 1.67%), and ore-derived indium (524,100 yuan, 0.02%). 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.
