What does the Jinzifeng–Huashan merger mean for Jiangxi’s lithium supply?

Yongxing and Canmax have announced plans to merge two adjacent lepidolite mines in Jiangxi, China's largest lithium-mica hub, in a deal Benchmark expects to delay fresh lithium supply in the near term even as it unlocks substantial output over the longer term. Under the deal, Canmax subsidiary Yichun Shengyuan Lithium will inject its Jinzifeng mine, valued at RMB 2.7 billion (~$396 million), into Yongxing's Huaqiao Mining in exchange for a 50% stake, with both parties then applying for a single unified mining right designed for 18 million tonnes of ore per year.

Greenbushes downgrades production guidance as ore grade decline accelerates

Greenbushes, the world’s largest hard-rock lithium mine, is struggling with a structural decline in ore feed grade that is now materially impacting production and costs. IGO announced this week that spodumene concentrate output for Q1 was 351kt, prompting a full-year FY26 guidance cut to 1,375–1,425kt from 1,500–1,650kt. Benchmark’s Q1 2026 lithium supply forecast had Greenbushes at approximately 270,000 tonnes LCE for 2026 calendar year, underpinned by 1,850kt of spodumene concentrate across the year. The March quarter result, and the likelihood of a softer Q2, means the first half of 2026 is now tracking approximately 170kt SC below our forecast, equivalent to a shortfall of roughly 25,000 tonnes LCE.

Lithium feedstock concerns over Nigeria port, security challenges

Lithium feedstock concerns over Nigeria port, security challenges

Port congestion at Lagos, licence fee increases, and a deteriorating security environment in northwest Nigeria are constraining spodumene concentrate exports to China. Q1 2026 shipments are tracking well below Nigeria’s mining and concentrating capacity, with market participants pointing to a structural trade imbalance at Lagos as the primary bottleneck. Terminal operators there have periodically suspended the reception of returned empty containers, citing saturated yard space.

Zimbabwe to lift lithium concentrate export ban with stringent conditions

On 2nd April, Zimbabwe's Minister of Mines and Mining Development outlined the prerequisite conditions for lifting the country's ban on lithium concentrate exports, signalling a potential thaw in the export suspension imposed in February 2026. The move reflects the government's intent to unlock value from the sector while enforcing strict domestic beneficiation requirements and operational standards. The conditions, detailed in a letter to the Chamber of Mines, represent a high bar for operators and reveal significant friction points between Zimbabwe's policy ambitions and the economics facing miners and converters.

What does Albemarle’s idling of Kemerton mean for Australia's lithium outlook?

What does Albemarle’s idling of Kemerton mean for Australia's lithium outlook?

Albemarle plans to idle its 25ktpa capacity Kemerton lithium hydroxide processing plant in Western Australia, citing “challenges facing Western hard-rock lithium conversion operations”. Kemerton processes spodumene from Albemarle’s Greenbushes mine into lithium hydroxide. In 2025, it produced an estimated 7.5kt LCE and was forecast to produce 22kt LCE in 2026. Expansions planned for 2029 could have added 75ktpa capacity. The idling of Kemerton materially weakens the near-term outlook for Australian lithium chemical refining as Kemerton was forecast to account for 46% of the country’s lithium chemical output in 2026 and had the potential to increase this to 49% by 2036.

PLS lithium offtake reinforces structural support in spodumene market

PLS lithium offtake reinforces structural support in spodumene market

Australian lithium miner PLS has executed a two-year binding offtake agreement with Canmax, a Chinese battery materials producer, for up to 150ktpa of spodumene concentrate (SC) starting in mid-2026. The deal includes a floor price of US$1,000/t and is subject to a US$100m unsecured, interest-free prepayment. There is an option to extend the offtake a further 12 months. The price floor is comfortably above the costs of PLS’ Ngungaju plant. It is also consistent with Benchmark’s view that hard-rock feedstock will be supported above US$1,000/t through 2026.

Restart of CATL’s Jianxiawo lithium mine may be delayed, tightening balance

Market expectations around the restart of CATL’s Jianxiawo lithium operation are increasingly diverging from Benchmark’s base-case assumption that production would resume shortly after the Lunar New Year which takes place in February this year. Claims circulating in the market this week indicate Jianxiawo requires remediation related to inadequate tailings pond impermeability and its proximity to

Why are lithium prices in China soaring this week?

Lithium prices in China have risen sharply this week, driven by the convergence of steadily tightening inventories, improving demand expectations, and improved macroeconomic sentiment. Battery-grade lithium carbonate and hydroxide inventories in China have been consistently drawn down since September 2025 and are now lower than at any time in 2025. With inventories depleted, the market […]

What do the recent Jiangxi permit cancellations mean for the lithium industry?

Benchmark’s long-held view that regulatory enforcement across China’s lithium sector is consistently tightening, rather than being episodic, was supported by the cancellation of 27 expired mining licences across Jiangxi by Chinese regulators in mid-December and the issuance of an Action Plan for Comprehensive Solid Waste Management. While neither development removes active lithium supply from the […]
