PLS boosts Pilgangoora's lithium mineral resource base by nearly a quarter amid supply glut
PLS, formerly known as Pilbara Minerals, has boosted the estimated lithium contained within Pilgangoora by 23 per cent to 446 million tonnes at 1.28 per cent lithium oxide (Li2O), which equates to 5.7 million tonnes of Li2O.
The mineral resource upgrade followed a 104,672-metre drilling program comprising 364 holes drilled within the past two financial years.
Shares in PLS spiked more than 10 per cent in early Wednesday trade, before paring back to a 3.5 per cent gain by 11.40am.
'The significant uplift in the mineral resources reaffirms our 100 per cent-owned Pilgangoora operation as one of the world's largest and highest-quality hard rock lithium assets,' PLS chief executive Dale Henderson said.
'This outcome is aligned with our strategy to optimise the operating base and unlock the full potential of this world-class asset, driving long-term value for our shareholders.'
PLS wants Pilgangoora to pump out more spodumene concentrate, despite a prolonged market recession.
Pilgangoora produces about 500,000 tonnes of the lithium product annually and is eyeing an increase to 850,000tpa — dubbed the P850 project. PLS has outlaid the capital required for P850.
The benchmark price of the spodumene concentrate all of WA's lithium miners export is currently languishing between $US605 per tonne and $US630/t, down about a quarter this year to date and more than 80 per cent from a 2022 peak.
All of the six lithium mines in Western Australia are believed to be losing money at current prices. A PLS spokesman on Friday indicated there are no plans to switch Pilgangoora off.
'The lithium market is moving through a phase of re-balancing. PLS is well positioned to navigate current conditions and capitalise on future recovery, underpinned by a multi-year strategy to scale the business, lower operating costs, and maintain a strong balance sheet,' the spokesman said.
'Combined with an embedded culture of continuous improvement to drive ongoing efficiency, this positions PLS strongly for the next phase of the cycle.'
Mineral Resources and Ganfeng's Mt Marion lithium mine appears to edge out Liontown Resources' Kathleen Valley as the least profitable lithium mine in the State.
But a MinRes spokesman told The West Australian on Thursday there were no near-term plans to put Mt Marion, or the company's other lithium mine Wodgina, into care and maintenance.

What's behind the recent lithium surge?
Pilbara Minerals chief executive Dale Henderson says it's too early to call a major shift in the market after the price of lithium spodumene surged more than 30 per cent during July. The price is down 86 per cent since January 2023.

Lithium might be back but the ride will be wild
There's been some violent gyrations in lithium markets over the past couple of weeks but sentiment appears to be turning. Liontown Resources (ASX:LTR) managing director Tony Ottaviano pointed out on Tuesday that spodumene futures had surged by US$60 per tonne on Friday but then dropped by US$50/t on Monday. 'Notwithstanding that, we've seen some green shoots in the past two weeks,' he said. Pilbara Minerals (ASX:PLS) managing director Dale Henderson is cautiously optimistic. 'There are signs the lithium winter may be lifting, but it's early in this change,' he said yesterday. 'The lithium market has long been marked by volatility, with prices prone to sharp and sometimes counterintuitive swings. 'The volatility is not incidental. It reflects a still nascent market with limited liquidity, few futures mechanisms and undeveloped trading infrastructure. Pricing remains inefficient. 'In this environment, short term moves are often driven by sentiment, policy signals or speculative flows, rather than durable shifts in supply and demand.' Henderson pointed that the price had sunk to levels over the past year that made much of the global lithium sector unprofitable. 'This was not the result of a fundamental oversupply alone, but an immature market that remains in development,' he said. 'The recent price rally, which began late in the June quarter and accelerated into July, follows this pattern, a sentiment-led rebound triggered by perceived supply risks. 'In this case, Chinese regulatory reviews of brine and lepidolite operations and the suspension of a major project fuelled renewed price momentum.' According to reports, eight lithium mines in Jiangxi are being scrutinised, which could potentially lead to suspensions. Shanghai Metals Market's baseline forecast for August was a 300 tonne surplus, but it suggested even limited disruptions could reduce monthly supply by 2000-2500t. In the case of moderate disruption, meaning a temporary suspension of Jiangxi mines, the impact would be 8000-10,000t in August, easing to 5000t a month by the December quarter. If mines are completely shut down, it forecasts a 10,000t impact to supply in August, escalating to 14,000t a month by the end of the year. 'Now, we remain cautiously optimistic but continue to monitor whether the flagged supply side adjustments will eventuate,' Henderson said. Picking the bottom Joe Lowry, the US-based founder of advisory Global Lithium, believes the lithium winter has ended. 'I believe the market has bottomed and we've started the next cycle,' he said in a video posted to X. IGO boss Ivan Vella yesterday seemed less convinced, commenting on the unseasonably cold winter in Perth this year and comparing it to the lithium winter. 'I suspect it'll warm up in Perth a lot before we see a real shift in the lithium market,' he said. Henderson cautioned it was a partial correction at this stage and not yet a full recovery and prices still remained well below the levels needed to incentivise new production. 'While near-term pricing is volatile, the long-term demand picture remains robust and continues to strengthen,' he said. He said global electric vehicle sales reached five million units in the June quarter, up 27% year-on-year, while EV penetration hit 50% in China in June and 25% for the rest of the world. Energy storage system demand is also building. 'Forecasts indicate 40% year-on-year growth for ESS in this calendar year alone,' Henderson said. 'Together, EVs and ESS are expected to account for something like 90% of lithium demand by 2030, highlighting a powerful and durable and structural demand trend.' Late last week, Canaccord Genuity analysts conceded that demand was much stronger than it expected and low pricing had hollowed out future supply growth. 'As demand growth overtakes supply growth, we see a much tighter market and potential for continued pricing improvements,' the firm's research team, led by Reg Spencer, said. 'There still appears to be oversupply today, but we think demand growth is rapidly eating into this. By 2027, additional will supply be needed and in the absence of higher incentive levels, this could elicit a more dramatic pricing response. 'We think the down cycle in the sector has now likely passed and see lithium equities as set to benefit.' What about juniors? The renewed optimism has flowed down into the junior space. Explorer Perpetual Resources (ASX:PEC) has more than doubled this month after completing the maiden drill program at its Igrejinha project in Brazil's 'Lithium Valley', which is also home to PLS' advanced Colinas development project. Canadian players Patriot Battery Metals (ASX:PMT) and Green Technology Metals (ASX:GT1) have surged, with each adding critical minerals components to their lithium resources. Western Australian junior Global Lithium Resources (ASX:GL1) is up by more than 45% over the past month, while fellow WA explorer Delta Lithium (ASX:DLI) is up by more than 25% over the same period. Argentina-focused Pursuit Minerals (ASX:PUR) is up 24% this month and managing director Aaron Revelle last week told Stockhead he could feel the change in sentiment on the ground. 'There's more inbound interest, especially those looking to secure supply outside of China,' he said. 'Juniors with pilot scale production, strong grades, and a clear pathway to development are getting a second look. It's cautious optimism, but the tone has improved from earlier this year.' Astute Metals (ASX:ASE) is taking advantage of the 20% rise in its share price over the past few days to raise fresh capital to continue advancing its Red Mountain lithium project in Nevada. It comes after the company reported high-grade hits of 62.4m at 1210 parts per million lithium from 152.2m, including 27m at 1420ppm lithium and 33.8m at 1130ppm lithium from 34.8m, including 10.7m at 1320ppm lithium on Friday. The results will underpin an initial resource estimate to be reported by the end of the year. Meanwhile, Chariot Corporation (ASX:CC9) is positioning itself for the recovery and China's strong demand by picking up new ground. Earlier this month, the company picked up the largest portfolio of lithium assets in Nigeria, which managing director Shanthar Pathmanathan described as a global lithium hot spot.

ASX Resources Quarterly Wrap: Lithium bounce could boost these junior explorers
Electric vehicle sales surge 30% sparking lithium price boost Major lithium miners climb on expectation of rising demand Anson defines maiden Green River Resource in June quarter Burgeoning global electric vehicle sales – up 30% to date according to Canaccord Genuity – have boosted lithium prices on expectations that demand for the battery metal will advance in lockstep. Price reporting agency Fastmarkets had last Tuesday assessed 6% Li2O – the benchmark for the spodumene concentrate mined by WA producers – at US$760/t, a significant gain from the low of US$610/t on June 23, 2025. This is due to rising futures prices in China and improved buying interest from battery makers, as well as the closure of a number of Chinese operations on environmental grounds. Lithium carbonate prices have also risen in the same period from US$8050/t to US$8550/t. This has proved to be a boon for lithium producers with Mineral Resources (ASX:MIN) rising 37% since July 1, 2025, to $29.80 while Pilbara Minerals (ASX:PLS) has put on 23.2% to $1.67 in the same period. Juniors have also gained from the improved lithium sentiment, and here are some companies that have been progressing operations during the June 2025 quarter… Anson Resources (ASX:ASN) During this period, Anson defined maiden JORC resources of 103,000t of contained lithium carbonate equivalent at its Green River project in Utah. The estimate is based on the drilling on the Bosydaba #1 well and could be increased in the near-term through the re-entry of the historical Mt Fuel-Skyline Geyser 1-25 well in the current quarter. Anson has also added 100 strategic placer claims to increase the Green River landholding by 10%. About 28% of these fall within the Area of Influence and will be included in subsequent JORC Mineral Resource estimates upgrades. Further resource upgrades could come from recent swabbing programs returning consistently higher assay values. Other steps taken by the company include entering into a non-binding memorandum of understanding with POSCO Holdings to collaborate on the construction of a direct lithium extraction demonstration plant, and working with the Utah state government to develop a new, lower state royalty rate scaled from 1% to 5% based upon market conditions compared to the previous flat rate of 5%. Delta Lithium (ASX:DLI) During the June 2025 quarter, Delta spun out its Mt Ida gold asset into new ASX-listed company Ballard Mining (ASX:BM1) to focus on its lithium assets. It also expanded the footprint of its Yinnetharra lithium and tantalum project through two transactions – the acquisition of Minerals 260's (ASX:MI6) Aston project and Zeus Resources' (ASX:ZEU) Mortimer Hills project. These have added 1778km2 to Yinnetharra, taking the total land package up to over 3100km2. Both assets have highly prospective tenure, are under-explored and host compelling targets for immediate exploration. Delta has also updated resources at Yinnetharra to 21.9Mt at 1% Li2O and 39.4Mt at 102ppm tantalum. The company has started systematic geochemical sampling and mapping over priority areas with passive seismic surveying to follow this year along with drill testing at Jamesons and adjacent prospects along the Leake Springs meta-sediment package in the following quarter. First Lithium (ASX:FL1) First Lithium continues to work closely with the Mali government to finalise renewals for its Gouna and Faraba permits. Discussions have also indicated the maiden resource will be finalised with results released in the current quarter. The Mali government had earlier this year announced plans to partially lift the suspension of mining permits that had been in place since September 2022 from March 15, 2025. The company has received a letter from the National Director of Geology and Mines in Mali confirming geophysical survey work can continue on both permits while direct meetings have confirmed the requirements for the licence renewal process. Chariot Corporation (ASX:CC9) Meanwhile, Chariot acquired a 66.7% interest in one of the largest hard rock lithium portfolios in Nigeria for US$1.5m in cash and 42 million shares in the company. The assets cover ~254km2 across the Fonlo, Gbugbu, Iganna, and Saki projects in Oyo and Kwara states. These contain a mix of licence types: exploration licences (ELs) for large-scale exploration and small-scale mining leases (SSMLs) over known mineralisation which provide Chariot with an opportunity to investigate fast-track development options. Notably, the Nigerian tenements have historically produced several thousand tonnes of spodumene concentrate for export to Chinese customers between 2021 and 2024, validating both the quality of mineralisation and existence of buyers. Chariot plans to start systematic exploration across the Nigerian portfolio, with initial field programs underway and first drilling targeted for late 2025. Separately, the company is awaiting results from Phase 2 drilling at its Black Mountain lithium project in Wyoming. It is also monitoring developments at neighbouring projects to its Resurgent project in the McDermitt Caldera on the border of Nevada and southern Oregon.
