[SMM Shanghai Spot Copper] Looking ahead to tomorrow, SHFE copper prices are expected to rise intraday and remain at a relatively high level. Coupled with the futures contract rollover, trading activity is likely to be muted, reflecting that the current price level is significantly suppressing real demand. After the rollover, the market will officially price around the 2607 contract, and close attention should be paid to the outflow of unmatched warrants. However, open interest for the SHFE copper 2606 contract currently stands at approximately 5,500 lots, indicating limited delivery participation. The concentrated release of warrants is therefore expected to exert relatively limited additional pressure on spot discounts. Supported by delivery-related dynamics, Shanghai spot copper discounts did not see a sharp decline. But if copper prices remain at current highs and demand fails to improve effectively, spot premiums may come under downward pressure.

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.

SMM News Flash: [Rebar] Today, export FOB prices for rebar rose slightly by about USD 2/tonne. According to market traders, inquiry activity was relatively decent, but actual transactions remained average. Some participants also noted that long steel demand in South America has been relatively stable recently, while demand in the Middle East remains weak. Regarding the US–Iran peace agreement, there has been no significant change in order flow so far, and overall market sentiment remains cautious and wait-and-see. [Billet] Today, export billet offers increased slightly by around USD 2/tonne, with prices at approximately USD 473–476/tonne FOB. Market feedback indicates that countries such as Indonesia and India are actively exporting billets, leading to intensified competition. However, domestic export price advantages are not obvious, as rising production costs are limiting steel mills’ willingness to discount, while traders are also more cautious in taking short positions. As a result, overall transaction activity remained moderate. [HRC] Today, export prices for flat steel products rose by USD 2/tonne day-on-day. Hot-rolled coil transaction prices were in the range of USD 497–506/tonne. Market inquiry activity was moderate, with no significant release of concluded deals. Recently, there have been some new inquiries for medium and heavy plate in the Middle East, with a portion of them resulting in transactions. [India] Ship-breaking scrap prices in the Alang (Gujarat) market increased by around 3 USD/tonne, with HMS (80:20) assessed at approximately 373 USD/tonne EXW. Semi-finished steel prices remained broadly stable, while finished steel saw a mild correction in the previous trading session. Market sentiment in Alang stayed subdued, as vessel arrivals remained at historically low levels. Strong freight economics continued to incentivize shipowners to extend the operating life of older vessels, limiting scrap inflows. In the near term, Alang scrap prices are expected to remain supported but constrained by tight supply conditions, with further movement largely dependent on vessel arrivals and downstream steel demand. [Thailand] Galvanizing quotes in the Thai market remained stable in the short term, with import offers still around 710 USD/tonne; however, for large-volume firm orders, the market could consider offering a discount of 5-10 USD/tonne. Wire rod quotes were also relatively stable, but some traders had to push up prices by 20 USD/tonne to 570 USD/tonne due to rising costs. In terms of local market transactions, downstream end-use demand was weak, and actual deals mostly shifted to a "negotiate deal by deal" model. It is expected that in the short term, Thai wire rod and galvanizing prices will hover at highs. Whether prices can subsequently stabilize on a solid footing will mainly depend on the release of downstream firm orders and the final bargaining and concession room offered by sellers under shipment pressure. [South Korea] Facing the approaching rainy season, South Korean builders are racing against time to push forward the final “intensive rush to meet deadlines” for foundation and main structure works, and the upward momentum of finished steel prices has slowed significantly. Today, POSCO’s two core steelworks (Pohang and Gwangyang) simultaneously raised the purchase price of high-quality pig iron scraps/premium steel scrap by 15,000 won/tonne (approximately 9.93 USD/tonne), and medium and light scrap by 10,000 won/tonne (approximately 6.62 USD/tonne), mainly to prevent domestic supply from being snapped up by other EAF steel mills before the off-season arrives. POSCO had no choice but to raise buying prices against the trend to “lock in” domestic spot cargo flows.

Today HRC futures held up well, with the most-traded contract settling at 3,397, up 0.68%. In the spot market, spot HRC offers rose 10-20 yuan/mt in many regions, while cold galvanized prices remained largely stable, and overall transaction performance was moderate. In news, the National Development and Reform Commission (NDRC) and other authorities issued a notice on launching a three-year campaign to promote energy-saving and carbon-reduction transformation in key industries. Starting from 2026, focusing on nine industries including steel, aluminum, cement, flat glass, oil refining, ethylene, synthetic ammonia, methanol, and coal power, comprehensive transformation will be carried out over three years; attention will be paid to subsequent implementation and progress. Outside China, Pakistan’s prime minister said on the 15th local time that after intensive negotiations, the US and Iran had reached a peace agreement, and Trump said the Strait of Hormuz would be fully opened. On the fundamentals, HRC inventory is expected to continue destocking this week, with limited accumulation of fundamentals. Considering the overall weakening demand during the off-season, steel prices lack self-driving force. In the short term, they are expected to hold up well, following raw material prices. Attention needs to be paid to the changing Middle East situation and its impact on future export orders.

The global secondary copper industry is at a critical juncture defined by tightening resources, green transformation, and intensifying global competition. As environmental protection policies continue to tighten and the energy crisis deepens, secondary copper—with its notable environmental advantages and economic value—is playing an increasingly prominent role in alleviating tight supply of primary copper and driving low-carbon development. Currently, the global copper industry chain is under multiple pressures, including supply fragility, demand transformation, and low-carbon upgrading. Major economies have listed copper among critical minerals, and international competition for secondary copper resources is becoming ever more intense. Optimizing the industry chain structure, improving recycling and recovery efficiency, and aligning global standards have become urgent priorities for the sector. To help the industry gain a comprehensive understanding of global policy trends and market dynamics.

[SMM Shanghai Spot Copper] Looking ahead to tomorrow, SHFE copper prices are expected to rise intraday and remain at a relatively high level. Coupled with the futures contract rollover, trading activity is likely to be muted, reflecting that the current price level is significantly suppressing real demand. After the rollover, the market will officially price around the 2607 contract, and close attention should be paid to the outflow of unmatched warrants. However, open interest for the SHFE copper 2606 contract currently stands at approximately 5,500 lots, indicating limited delivery participation. The concentrated release of warrants is therefore expected to exert relatively limited additional pressure on spot discounts. Supported by delivery-related dynamics, Shanghai spot copper discounts did not see a sharp decline. But if copper prices remain at current highs and demand fails to improve effectively, spot premiums may come under downward pressure.

On June 6, under the precise matchmaking and full support of the finance bureau of the Sanmenxia Urban-Rural Integration Demonstration Zone (High-tech Zone), Henan Qianbiao Industrial Group Co., Ltd. and Sanmenxia High-tech Investment Group Co., Ltd. successfully signed a cooperation agreement for the project of secondary aluminum recycling and alloy plate and coil rolling production and processing with an annual capacity of 100,000 mt in the zone, marking the official launch of the cooperation project between the two parties.

[SMM Shanghai Spot Copper] Looking ahead to tomorrow, next Monday marks the last trading day for the SHFE copper 2606 contract. According to SMM's #1 copper cathode price assessment methodology, SMM always quotes against the front-month contract. During the day, the center of copper prices moved up, and downstream procurement sentiment pulled back slightly, indicating that high prices somewhat curbed demand. Approaching delivery, suppliers showed a relatively strong willingness to deliver their open interest, keeping available cargo tight. In addition, spot inventory in the Guangdong region remained at a low level, with offers at a premium of around 200 yuan/mt, which may lend some support to premiums in the Shanghai region. Overall, premiums for Shanghai spot copper against the SHFE 2606 copper contract next Monday are expected to remain at a premium level.

Domestic Selenium Market Remains Weakly Stable Amid Seasonal Lull and Increased Supply

On June 9, a fire broke out at Chemical Grade Plant 3, or CGP3, at the Greenbushes lithium operation. The fire was quickly extinguished, no injuries were reported, and CGP1 and CGP2 continued to operate as normal. The following day, IGO confirmed that its FY2026 spodumene concentrate production guidance of 1.375–1.425 million tonnes remained unchanged. Chemical Grade Plant 4, or CGP4, is scheduled to commence construction in 2027. Viewed in isolation, this was a well-contained operational incident. However, the location of the fire deserves closer attention. CGP3 is not part of Greenbushes’ existing production base. It represents incremental supply currently ramping up at the far-left end of the global lithium cost curve. The project involved approximately A$880 million of investment and is designed to add around 500,000 tonnes per year of spodumene concentrate capacity. First ore was fed into the plant in December 2025, and the facility had originally been expected to reach nameplate capacity around mid-2026. The damage assessment is still under way. Neither the repair cost nor the recovery timeline has been quantified. The fact that production guidance remains unchanged should therefore be understood as an initial assessment rather than a definitive conclusion. The key question is not whether IGO has immediately revised its annual guidance. It is whether the CGP3 ramp-up schedule will be delayed. Should the market be concerned when an incremental production line at the world’s lowest-cost lithium mine experiences an operational disruption? To answer this question, it is useful to examine the role of Australian lithium mines in the broader lithium pricing mechanism. Note on the CGP3 ramp-up timeline: At IGO’s FY2026 second-quarter results briefing in late January 2026, management stated that CGP3 had received first ore in December 2025 and would require approximately five months to ramp up to nameplate capacity. Some English-language transcripts recorded management as referring to completion “by the end of the calendar year.” However, based on the timing of first ore feed, a five-month ramp-up period would imply completion around mid-2026, before the end of Australia’s FY2026 financial year. This is also consistent with the company’s previous guidance. The transcript may therefore have intended to say “by the end of the financial year.” This article adopts the mid-2026 ramp-up assumption. The timing is relevant because the June 9 fire occurred only weeks before the originally expected completion of the ramp-up. The actual impact should become clearer in IGO’s fourth-quarter report, which is expected in late July. Greenbushes: A Reference Point at the Bottom of the Cost Curve Greenbushes’ most important advantage begins with ore grade. It is one of the world’s largest and highest-grade hard-rock lithium mines currently in production. Its ore grade is approximately twice the industry average. For a spodumene operation, grade directly affects processing efficiency. To produce one tonne of SC6 concentrate, Greenbushes needs to process materially less ore than a typical mine. This provides a structural advantage across mining, beneficiation, energy consumption and tailings management. Greenbushes also benefits from scale. The operation currently has several processing facilities, with combined nominal ore-processing capacity of around 6.5 million tonnes per year and spodumene concentrate capacity of up to approximately 1.5 million tonnes per year. Once CGP3 completes its ramp-up, the mine will add a further 500,000 tonnes per year of concentrate capacity. With the mine life extended to 2045, Greenbushes combines low costs with long-term supply capacity. This explains the mine’s resilience during the lithium price downturn. During 2024 and 2025, lithium prices declined sharply. A number of higher-cost Australian mines and Chinese lepidolite projects faced production cuts or temporary shutdowns. Greenbushes, however, continued to maintain relatively strong profitability and moved ahead with the CGP3 expansion. Greenbushes does not represent the industry’s average cost. It represents the most competitive end of the global hard-rock lithium cost curve. For that reason, Greenbushes is better understood as a reference point for the bottom of the cycle. As lithium prices fall, higher-cost supply exits first, while low-cost assets remain in operation. The closer prices move toward the cost range of Greenbushes, the fewer marginal producers remain capable of operating normally, and the more advanced the supply-side clearing process becomes. This does not mean that lithium prices can never fall below the cost level of Greenbushes. In the short term, inventory pressure, liquidity conditions and market sentiment can push prices below the cost levels implied by the marginal supply curve. Greenbushes is not an absolute price floor. Its significance is that it provides a structural reference point for assessing how far supply-side clearing has progressed. Greenbushes: The Largest Producer, but with Limited Freely Traded Supply Although Greenbushes produces large volumes of spodumene concentrate, relatively little of that material enters the open spot market directly. The mine is operated by Talison Lithium. Talison is owned by Tianqi Lithium Energy Australia, or TLEA, and Albemarle. TLEA is in turn jointly owned by Tianqi Lithium and IGO. Greenbushes concentrate is primarily distributed through shareholder offtake arrangements and supplied into the downstream conversion systems of Tianqi, Albemarle and their respective partners. Under normal conditions, the material is not sold directly into the open market. Greenbushes therefore provides a useful example of why lithium supply should be analysed through several different layers: Resources → Design capacity → Actual production → Saleable volume → Freely traded spot volume Greenbushes ranks among the world’s largest producers by actual output. However, because most of its concentrate is locked into shareholder offtake arrangements, the amount available for open-market trading remains relatively limited. This means Greenbushes affects lithium pricing mainly through indirect channels. First, it determines the size of the lowest-cost portion of global lithium supply and therefore plays an important role in shaping the lithium chemical cost curve. Second, its operating costs, offtake pricing mechanism and expansion schedule provide reference points for long-term contract negotiations and price assessments in the spodumene market. By contrast, short-term spot prices are often more directly influenced by marginal resources that are not fully locked into shareholder arrangements and must actively seek buyers in the market. These include certain Australian mines, African lithium resources and trader-held cargoes. This explains an apparent paradox. An additional 500,000 tonnes of Greenbushes concentrate capacity can materially change the medium-term supply-demand balance, yet its immediate impact on the spot market may be limited. Meanwhile, the shutdown or restart of a marginal mine producing only 100,000–200,000 tonnes per year can quickly influence spot quotations and market sentiment if its output is sold on a market basis. Short-term pricing is not determined solely by total production. It is also shaped by the volume of material that is freely available for negotiation and immediate transaction. The same logic applies to lithium carbonate. Price elasticity depends not only on total inventory but also on how much inventory is genuinely available for circulation. The largest producer does not necessarily exert the most direct influence over the spot market. Short-term marginal pricing is usually driven by the resources that are tradeable, negotiable and available for immediate delivery. However, shareholder offtake does not mean that Greenbushes material is completely isolated from the market. If lithium conversion plants within the Tianqi or Albemarle systems reduce operating rates, or if downstream conversion assets experience operational issues, part of the concentrate originally intended for internal consumption may re-enter the market indirectly through tolling, resale or inventory adjustments. These volumes are rarely captured in public statistics, but they can affect the actual liquidity of the spodumene market. Tracking this material requires a broader set of indicators, including shareholder conversion-plant operating rates, concentrate inventories, tolling arrangements and import flows. This type of “shadow spot supply” is harder to observe than nominal mine production, yet it can become relevant at specific points in the cycle. SC6 and Lithium Chemicals: The Direction of Price Transmission Reversed Within a Year The relationship between Australian spodumene concentrate prices and Chinese lithium chemical prices has completed a full cycle over the past year. During the first half of 2025, spodumene prices followed lithium chemical prices downward. Australian miners reduced costs materially in the first quarter but largely avoided production cuts. Mining companies remained willing to ship material, and the price of SC6 concentrate fell to around US$620 per tonne. Falling concentrate prices then placed additional pressure on lithium chemical prices, reinforcing the downward cycle. At the time, the key market question was straightforward: When would the mining sector finally reduce supply? The direction of transmission reversed in the end of third quarter. The announcement that 27 mining licences in Yichun could be cancelled, together with the suspension of the Jianxiawo mine, tightened expectations around domestic Chinese lithium supply. Lithium chemical prices moved first. SC6 prices then followed, with greater elasticity. By December, the monthly average price had recovered to around US$1,300 per tonne. Formula-based pricing mechanisms linked to lithium chemical prices allowed mining companies to capture a large share of the upside, while Chinese converters saw their processing margins squeezed. At the same time, the impairment and expansion adjustments at the Kwinana lithium hydroxide project highlighted the challenges facing Australian downstream conversion. The project has faced difficulties in cost control, production ramp-up and operational stability. TLEA’s Kwinana lithium hydroxide refinery was fully impaired in mid-2025, the second train was suspended, and IGO made clear that it would prioritize mining. These developments reinforce Australia’s role as a supplier of spodumene concentrate rather than a major lithium chemical conversion hub. As a result, the relationship between SC6 prices and Chinese lithium chemical prices is likely to remain strong. However, the speed and magnitude of transmission will continue to depend on inventories, contract formulas, shipping cycles and converter operating rates. One of the most useful indicators is the implied conversion margin between SC6 concentrate and lithium chemical spot prices. When the implied conversion margin turns negative, Chinese converters purchasing third-party concentrate are effectively losing cash on incremental production. The market then needs to rebalance through at least one of three channels: Spodumene concentrate prices decline; Lithium chemical prices rise; Converters reduce operating rates. This indicator provides a useful way to judge whether bargaining power currently sits with the mining segment or the conversion segment. Australian Mine Restarts: Lithium Prices Develop an Upper Constraint The key theme for Australian lithium mines during 2024 and 2025 was supply-side clearing. In 2026, the theme has shifted toward reactivation. As lithium prices recovered during the first half of the year and futures briefly exceeded RMB 200,000 per tonne, a series of restart decisions emerged across May and June. Project Action Timing Key Point Bald Hill, Mineral Resources Restart after approximately 18 months of suspension Restart announced in May; first concentrate expected in July Restart cost of around A$20 million Ngungaju, PLS Processing plant restart Planned for July Approximately 200,000 tonnes per year of restored output Finniss, Core Lithium Final investment decision approved; financing secured Targeting first ore in the third quarter Financing package of approximately US$205 million Kathleen Valley, Liontown Expansion under assessment Ongoing Further details pending Mt Cattlin, Rio Tinto Remains suspended Suspended since March 2025 Restart conditions remain unclear Taken together, these cases show that the true threshold for mine restart is more complex than a simple comparison between lithium prices and cash costs. Bald Hill moved from restart announcement to expected first concentrate production in around two months. The mine had remained in a production-ready care-and-maintenance state, and Mineral Resources has its own mining-services platform, allowing it to mobilize mining, crushing and haulage internally without relying heavily on external contractors. This type of asset represents the fastest-reacting segment of supply when prices recover. Finniss is a different case. The project first monetized inventories through Glencore to improve liquidity, then assembled a financing package involving convertible debt, additional borrowings and equity issuance before reaching a final investment decision. For miners with weaker balance sheets, a restart is not simply an operational decision. It is a financing event. A low-price cycle does not eliminate the resource base. It eliminates the ability to finance production. The market impact of the restart wave is already visible. Lithium carbonate futures reached a two-year high of RMB 200,500 per tonne on May 13 before retreating to around RMB 160,000–170,000 per tonne in June. One reason for the pullback is that the market has begun to price in the return of idle supply. The mechanism is straightforward: Prices rise → Idle capacity restarts → Expected supply increases → Prices come under pressure The list of suspended Australian mines, once ranked by restart economics and response time, effectively becomes an upside supply curve for lithium prices. The CGP3 fire and the restart wave represent two sides of the same market. At the low-cost end of the curve, incremental Greenbushes supply has experienced an operational disruption, creating a bullish signal. At the higher-cost end, idle assets are returning to production, creating a bearish signal. From a resource perspective, lithium prices in 2026 are searching for equilibrium between these two forces. Lithium Prices in 2026 May Become More Volatile, but One-Way Trends Could Be Shorter Once prices rise, the factor that ultimately limits the upside is the speed at which idle capacity returns to the market. Bald Hill, Finniss and Ngungaju represent a broader pool of suspended or standby assets that can respond when lithium prices move sufficiently above their cash-cost thresholds and remain there for long enough. However, restart supply is not instantaneous. From the moment a restart is announced, companies need to remobilize personnel, inspect equipment, resume mining and processing, build concentrate inventories and arrange shipments. Depending on the asset, concentrate may enter the market within two months or only after several quarters. This delay creates a window during which supply disruptions can push prices higher. The suspension of the Jianxiawo mine and the CGP3 fire at Greenbushes matter not because global lithium resources have suddenly become scarce, but because short-term freely available supply has tightened while idle capacity has not yet fully returned. Compared with the previous cycle, this risk-premium window appears to be shortening. An increasing number of mines are being placed on care and maintenance rather than permanently closed. Mining-services companies, traders and downstream customers are also becoming more involved in restart financing and offtake arrangements. Once prices move back above the relevant breakeven levels, some idle assets can return more quickly. This does not necessarily mean lithium prices will become more stable. Supply disruptions can still trigger rapid price increases. However, the duration and magnitude of one-way rallies are likely to face stronger constraints from restart expectations. Prices may become more volatile in the short term, but sustained unilateral trends could become shorter. Conclusion Australian lithium mines influence lithium prices through several distinct channels. Greenbushes provides a structural reference point at the bottom of the hard-rock lithium cost curve. However, because most of its output is absorbed through shareholder offtake arrangements, it does not directly determine short-term spot pricing. Spot-market tightness is more directly influenced by marginal saleable supply: Australian mines, African resources and trader-held inventories that are available for negotiation and immediate transaction. Once lithium prices rise, the speed at which suspended assets restart becomes the key constraint on the duration of the rally. The framework can therefore be summarized in three lines: Low-cost mines provide a structural reference point for the bottom of the cycle. Freely traded supply determines short-term spot-market tightness. The speed of mine restarts determines how long an upside cycle can last. The CGP3 fire and the restart wave sit at opposite ends of this framework. One represents a disruption to low-cost incremental supply. The other represents the return of higher-cost idle capacity. Lithium prices in 2026 will continue to seek equilibrium between these two forces. Lesley Yang Senior New Energy Analyst, SMM yangle@smm.cn
