European Lithium Limited (ASX: EUR, FRA: PF8, OTC: EULIF) (European Lithium or the Company) is pleased to announce Critical Metals Corp. (Critical Metals or CRML) has entered into a share subscription facility for up to US$125.0M from GEM Global Yield LLC SCS (GEM), a Luxembourg based private alternative investment group. Proceeds from the facility are expected to be used to fund the development of the Wolfsberg Lithium Project in Austria (Wolfsberg or Wolfsberg Project).
HIGHLIGHTS
- Critical Metals has signed an agreement for a share subscription facility for up to US$125.0M in transaction funding from Global Emerging Markets (GEM)
- Critical Metals expects to provide an update on further equity funding in the near term
- Funding will principally be used to accelerate the development of the Wolfsberg Lithium Project in Austria.
Tony Sage, Chairman, commented: “Receiving this significant and binding commitment is a huge milestone for the Company. Combined with European Lithium’s recent deal with Saudi Arabian based, Obeikan Investment Group, the Company and Critical Metals have secured approximately 65% of the total expected capex of the Wolfsberg Project and brings us closer to our stated goal to be the first local producer of lithium spodumene for the green energy transition in Europe.”
Under the terms of the definitive agreement, Critical Metals will have access to up to US$125.0M in incremental capital to fund its operations upon closing of the business combination transaction. The facility would enable Critical Metals, in its discretion but subject to the terms and conditions set forth in the definitive agreements, to draw down funds (up to US$125.0M) through the issuance of new shares directly to GEM over a three-year period after the closing of the transaction. Assuming no further redemptions are made by public stockholders of Sizzle Acquisition Corp. (Sizzle) in connection with its shareholder vote to approve the transaction, Critical Metals would now be expected to have access to up to ~US$175.0M in transaction proceeds (comprising of the GEM finance package and existing cash reserves).
The GEM finance package, together with European Lithium’s additional funding secured through the binding term sheet with Obeikan Investment Group (Obeikan)(refer to EUR announcement dated 2 June 2023), are expected to provide Critical Metals and European Lithium with significant capital to accelerate the development of the Wolfsberg Project once the transaction with Sizzle completes.
The Company can report substantial progress has been made in the development plan for the Wolfsberg project with the achievement of several key milestones highlighted by:
- Mining permit secured - spodumene mined from the project successfully demonstrated its capability to supply high-purity lithium (99.6% lithium carbonate equivalent) at pilot plant.

European Lithium
Overview
As the global push to halt climate change gains momentum, the European Commission is looking to regionalize the battery supply chain to capitalize on the rapid electric vehicle (EV) growth and limit its dependency on other countries through heavy investment and policy changes. Europe’s electric vehicle market value reached US$29.49 million in 2021 and is projected to increase up to US$143.08 million by 2027, indicating a compounded annual growth rate of 23.4 percent in that period.
Even though Europe is one of the largest global producers of motor vehicles, it currently does not have a local supply of lithium hydroxide which is heavily used in EV battery technology. According to experts, the market is set to remain in a structural shortage until 2025
One company that aims to become the first local lithium supplier into an integrated European battery supply chain is European Lithium (ASX:EUR,FRA:PF8), a mining exploration and development company focused on exploring, identifying and acquiring lithium in Europe. The company is led by a management team with decades of experience and success in the mining and finance markets.“Our aim is to be the first supplier of lithium from Europe, for Europe,” European Lithium chairman Tony Sage said.
The company is focused on its wholly owned Wolfsberg Lithium project located in Carinthia, Austria. The pre-existing mine is located in a mining-friendly region with multiple mineral discoveries in the surrounding area. The property features a high-grade lithium resource at an average grade of one percent lithium hydroxide, with a total resource of 12.88 million tonnes based on resources measured, indicated and inferred in zone 1 only.
The Wolfsberg Lithium project resource has the potential to double based on positive drill results in another zone on the property.
Based on the definitive feasibility study (DFS) released in March 2023, Wolfsberg Lithium Project is well positioned to become a leading producer of battery-grade lithium hydroxide in Europe. It is set to deliver high returns, leveraging low operating costs, and benefiting from a lithium market that is anticipated to be in structural undersupply during most of the life of mine. The battery-grade lithium hydroxide monohydrate (LHM) prices modeled in the DFS are projected to be at a 39-percent discount to current spot prices in 2025 and then escalate by 2 percent per annum. The estimated capex is US$866 million which supports a post-tax NPV of US$1.5 billion.
European Lithium has established several strategic relationships with an aim to deliver value to the Wolfsberg Lithium Project through development and during production. This includes a partnership with KMI for liaising with Austrian authorities.
The company commissioned Dorfner Anzaplan to construct the pilot plant, which was successfully completed on schedule. Anzaplan has also overseen the completion of metallurgical test work on bulk ore extractions. Testing will allow significantly higher recovery rates at the start of production as opposed to only assessing metallurgical data from the core as other mining companies often do, giving European Lithium the advantage of a streamline refinement process.
The company has support from the European Battery Alliance, GREENPEG and other government initiatives, believing it has the potential to become a major, first-to-market producer of lithium in Europe. The company also remains committed to clean production in an effort to support sustainability.
Based on the DFS, the company plans to begin the permitting process of its Wolfsberg Lithium project and prepare the mining plan for the mining authority to authorize the mine and concentrator construction. Afterward, the company will determine the approval requirements of the carbonate hydroxide conversion plant with the Energy Information Administration (EIA) and then initiate the final financing plan.
European Lithium, through its wholly owned Austrian subsidiary ECM Lithium Aľ GmbH (ECM), signed a binding long-term lithium offtake agreement with top-tier European auto manufacturer BMW to secure the company’s first offtake of battery grade lithium hydroxide from its Wolfsberg Lithium Project in Austria.
The company is aiming to commence production of lithium hydroxide from the project in 2027 — subject to funding and approvals by the Austrian government.
In a bid to expand its project portfolio, European Lithium executed a binding Heads of Agreement with 2743718 Ontario Inc., a subsidiary of Richmond Minerals (TSXVRMD), to acquire 100 percent of the rights, title and interest in the Bretstein-Lachtal Project, Klementkogel Project and the Wildbachgraben Project, a group of exploration licenses covering 114.6 square kilometers, targeting lithium with known occurrences in the Styria mining district of Austria.Company Highlights

Rock Bottom: Strategic Window for Ground-level Lithium Investment in 2025
When lithium prices hit bottom, savvy investors know that’s exactly where the next big discovery begins — literally. Beneath the surface of global markets and remote exploration grounds, new opportunities are forming in the wake of a sharp price reset and renewed geopolitical urgency.
Macroeconomic and policy shifts in 2025 are creating ideal conditions for those willing to look past the headlines. While volatility in lithium prices has tempered short-term sentiment, the underlying demand trajectory remains strong. With governments reshaping supply chains to reduce reliance on China and accelerate the energy transition, lithium is emerging not only as a critical resource, but as a strategic investment theme with long-term upside.
For investors, this reset isn’t a retreat; it’s a rare chance to get in early, at ground level.
Critical metal for a low-carbon future
Lithium demand is being driven by structural, not cyclical, forces.
Global sales of electric vehicles are expected to reach 17 million units in 2025, up from just 6.6 million in 2021, according to a report from the International Energy Agency. At the same time, the rollout of renewable energy infrastructure has created a parallel boom in demand for lithium-ion batteries in stationary storage applications.
These trends have elevated lithium to the status of a strategic resource. The US, EU, Canada and Australia have all included lithium on their critical minerals lists, with policy frameworks and funding programs aimed at reshoring supply chains and reducing dependence on dominant producers such as China.
New landscape for investors
Three major forces are shaping the lithium market in 2025:
- Geopolitical realignments: China continues to dominate lithium refining and cathode production, but western economies are responding with policies that promote domestic and allied resource development. Africa, in particular, is emerging as a new frontier, offering significant untapped lithium reserves in relatively underexplored jurisdictions.
- Strategic consolidation: Major lithium producers are moving aggressively to secure future output. Rio Tinto's (ASX:RIO,NYSE:RIO,LSE:RIO) $6.7 billion acquisition of Arcadium Lithium, and SQM's (NYSE:SQM) joint ventures in Brazil and Australia reflect a renewed emphasis on long-term control of raw materials. These moves also signal confidence in lithium’s medium- and long-term pricing. Rio Tinto, in particular, remains “consistent in its belief in the long-term outlook for lithium,” according to a June 3, 2025, report from Reuters.
- Price volatility creates opportunity: Spot lithium prices experienced a steep drop in 2023 following the oversupply concerns post-2022 highs. But market watchers are now seeing signs of recovery as supply rationalizes and demand from automakers rebounds. For investors, downturns often mark the most opportune entry point — when high-quality assets are undervalued and underfunded.
Lithium Africa: A strategically aligned explorer
Amid this shifting landscape, junior exploration company Lithium Africa is capitalizing on timing, partnerships and geography. The company is focused on unlocking lithium potential across Africa, with an early focus on pegmatite-rich regions in Morocco, Zimbabwe, Côte d’Ivoire and Guinea — jurisdictions that are fast gaining attention as future pillars of global lithium supply.
Strategic partnership
One of Lithium Africa’s most distinctive value propositions is its technical and financial partnership with Ganfeng Lithium, one of the world’s largest lithium producers. Ganfeng brings deep chemical processing expertise and project development experience, providing critical de-risking support as Lithium Africa advances its early stage projects. Importantly, Ganfeng is matching every dollar raised by Lithium Africa — with $1 raised equating to $2 spent on exploration — an arrangement that reduces dilution, improves capital efficiency and signals external validation of project potential.
Raising capital at the bottom of the cycle
Unlike many juniors sidelined by the recent downturn, Lithium Africa is using the current market reset as a window of opportunity. The company has secured funding during the trough of the lithium cycle, allowing it to acquire prospective tenements at low cost and accelerate fieldwork, while competitors are cash-constrained or inactive. This countercyclical strategy is designed to generate value precisely when assets are overlooked by the broader market.
Efficient exploration for discovery-driven growth
Lithium Africa’s exploration model emphasizes efficiency. The company employs low-cost but technologically advanced geophysical and geochemical techniques to quickly evaluate and rank prospects before committing to intensive drilling campaigns. In regions like Zimbabwe — already home to several lithium occurrences — this approach allows for rapid advancement toward discovery. Should a world-class deposit be delineated, history shows that such a find is recognized and rewarded by both majors and markets, regardless of the broader cycle.
Africa's lithium frontier: Gaining global attention
Lithium Africa is part of a broader wave of explorers turning their attention to the continent. Companies such as Leo Lithium (ASX:LLL,OTC Pink:LLLAF) and Atlantic Lithium (ASX:A11,LSE:ALL,OTCQX:ALLIF) have drawn investor interest for their hard-rock projects in Mali and Ghana, respectively. Africa offers the geological potential, lower entry costs and increasing regulatory clarity that resource developers seek in a post-China supply chain strategy.
However, Lithium Africa’s differentiators — its timing, capital alignment and strategic partnership — set it apart in a competitive field.
Investor takeaway
The lithium market may be entering a phase of short-term volatility, but its long-term trajectory is defined by structural demand growth. For investors, the opportunity lies not just in producers, but in the well positioned explorers who can secure quality ground, deploy capital wisely and advance toward discovery with strong technical backing.
Companies like Lithium Africa, which align with geopolitical supply trends, partner with strategic industry leaders, and commit to efficient, high-impact exploration, offer a uniquely leveraged way to gain early exposure to the next chapter of global lithium supply.

Beneficiation Delivers 4,480ppm Lithium Clay Concentrate at Red Mountain Project, USA
Latest results reinforce ability to upgrade Red Mountain mineralisation
Astute Metals NL (ASX: ASE) (“ASE”, “Astute” or “the Company”) is pleased to report further positive results from the latest phase of beneficiation testwork for its 100%-owned Red Mountain Lithium Project in Nevada, USA. The results continue to strengthen the Project’s commercial development potential.
Key Highlights
- Follow-up Falcon C beneficiation testwork completed on diamond drill core samples from the Red Mountain Project.
- Sample upgraded from 3,245ppm to 4,481ppm Lithium.
- Successful removal of 51.8% of dense material and concurrent 38% increase in lithium grade.
- Reinforces the April 2025 results indicating that Red Mountain mineralisation may be upgraded using beneficiation.
- Attrition Scrubbing beneficiation testwork now underway for comparison with the Falcon testwork results.
- Leaching testwork to be undertaken on Falcon and Attrition Scrubbing products to confirm reduced acid consumptions.
Following on from the results announced on 22 April 2025, this second phase of Falcon Beneficiation testwork was designed to concentrate lithium-bearing clay and remove unmineralized gangue (waste) in order to decrease mass and increase lithium grade. In a mineral processing context, a reduction in tonnes and volume processed with an increased head-grade typically results in lower processing costs.
This second Falcon testwork program was conducted by Sepro Laboratories (Sepro) and utilised high- clay drill core samples from hole RMDD002 (which intersected 86.9m @ 1,470ppm Li from 18.3m4). This follow-up test was designed to establish how high-clay material performed using the Falcon method, for comparison with results from the previous test conducted on lower grade mineralisation from Red Mountain.
The latest result indicates a strong ability to upgrade mineralisation, achieving a reduction of sample mass by 51.8% with a concurrent increase in lithium grade of 38% (from 3,245 to 4,481ppm Li), with an overall 66.6% lithium recovery. These results compare favourably with the previous round of testwork, exhibiting both a greater upgrade in lithium and reduction in mass, with a substantial 43% reduction in calcium and carbon (interpreted as calcite removal) expected to result in a significant reduction in acid consumption. The Company has commissioned Attrition Scrubbing testwork – another method of beneficiation – for comparison with the Falcon results. Once complete, sample products from both the Falcon and Attrition Scrubbing tests will be assessed for acid consumption in future leachability tests.
Astute Chairman, Tony Leibowitz, said:“The demonstration of a commercial pathway to a lithium product is the natural complement to the establishment of a Mineral Resource. It is for this reason that Astute has actively advanced workflows for both exploration drilling and metallurgical testing at Red Mountain, in tandem. These positive results, which reinforce the previous results from the project, represent the systematic de-risking of what continues to emerge as an important US- based critical metals project.”
Figure 1. Clay-rich RMDD002 drill-core from 160-165ft (3,280ppm Li) used in Falcon beneficiation testwork.
Background
Located in central-eastern Nevada (Figure 4), adjacent to the Grand Army of the Republic Highway (Route 6), which links the regional mining towns of Ely and Tonopah, the Red Mountain Project was staked by Astute in August 2023.
The Project area has broad mapped tertiary lacustrine (lake) sedimentary rocks known locally as the Horse Camp Formation1. Elsewhere in the state of Nevada, equivalent rocks host large lithium deposits (see Figure 4) such as Lithium Americas’ (NYSE: LAC) 62.1Mt LCE Thacker Pass Project2 and American Lithium (TSX.V: LI) 9.79Mt LCE TLC Lithium Project3.
Astute has completed substantial surface sampling campaigns at Red Mountain, which indicate widespread lithium anomalism in soils (Figure 3) and confirmed lithium mineralisation in bedrock with some exceptional grades of up to 4,150ppm Li1,5.
A total of 19 RC and diamond drill holes have been drilled at the project to date for a combined 3,666m. Exploration drilling has been highly successful, with strong lithium mineralisation intersected in every hole for which assays have been received9.
Scoping leachability testwork on mineralised material from Red Mountain indicates high leachability of lithium of up to 98%, varying with temperature, acid strength and leaching duration, and proof-of- concept beneficiation testwork has indicated the potential to upgrade the Red Mountain mineralisation6,8.
About Beneficiation
The primary purpose of beneficiation is to optimise the value of mineralised material by separating unwanted waste material (gangue) from valuable minerals.
Testwork conducted to date at Red Mountain indicates that clay-hosted lithium mineralisation may be upgraded through beneficiation, which seeks to remove coarser grained material, such as particles of sand, that do not contain appreciable lithium8. Successful beneficiation can result in reduced reagent consumption, reduced plant wear and tear, and a reduced environmental footprint.

Pursuit Dispatchs 99.5% Lithium Carbonate Samples to Potential Strategic Partners as Feasibility Studies Progress
Pursuit Minerals Ltd (ASX: PUR) (“PUR”, “Pursuit” or the “Company”) is pleased to announce that high- purity lithium carbonate samples have been dispatched to multiple parties as part of its engagement with prospective offtake and strategic partners. The samples were produced from the Company’s 250tpa Pilot Plant in Salta, Argentina, using synthetic brine chemically identical to that of the Rio Grande Sur Lithium Project.
HIGHLIGHTS
- Final product assays confirm 99.5% lithium carbonate purity, upgraded from pilot output via bench scale processing.
- Certified samples dispatched to multiple potential offtake and strategic partners for qualification.
- Feasibility study progressing for low cost, 5,000tpa operation at Rio Grande Sur.
- Ongoing small batch lithium carbonate production to support offtake qualification while preserving capital discipline in current market conditions.
- Pursuit continues to advance its dual-pronged growth strategy progressing Rio Grande Sur while accelerating the evaluation of strategic gold, silver, and copper acquisitions in Argentina.
Figure 1 – Pursuit’s 99.5% Li₂CO₃ Sample Ready for Dispatch to Potential Offtake Partners
In relation to the dispatch of samples, Pursuit Managing Director & CEO, Aaron Revelle, said:
“Achieving 99.5% lithium carbonate purity is a major technical milestone for Pursuit and a clear demonstration of the capability embedded within our flowsheet, team, and pilot plant infrastructure. It not only validates the compatibility of our process design with Rio Grande Sur brines but also confirms our ability to deliver a consistently high-quality product suited to a wide range of industrial and energy storage applications. Dispatching these samples to potential offtake partners is a critical first step in our commercialisation pathway, enabling product qualification and accelerating engagement with strategic customers in tough market conditions. As we transition into the next phase of development, our focus is firmly on advancing feasibility for our 5,000tpa operation and securing long-term partnerships that will underpin the future production and growth of the Rio Grande Sur Project.”
Initial pilot production at Pursuit’s 250tpa Pilot Plant in Salta successfully produced 15 kilograms of lithium carbonate at 98.9% purity, validating both the compatibility of the Rio Grande Sur brine and the efficiency of the Company’s conventional processing flowsheet. To enhance product quality and simulate potential refinement steps at commercial scale, a portion of this material was further treated at bench scale using fractional crystallisation (FX) and ion exchange (IX) techniques. These post processing steps upgraded the product to 99.5% purity, meeting established benchmarks for technical-grade lithium carbonate.
The final product assays confirm not only the effectiveness of Pursuit’s downstream purification strategy but also the scalability and robustness of its broader flowsheet. This achievement represents a critical milestone on the path to commercial readiness supporting key feasibility assumptions, validating end product quality, and enabling active engagement with prospective offtake partners.
Pursuit is well positioned to undertake additional small-batch production as required to meet partner qualification needs and advance strategic discussions. Furthermore, it demonstrates Pursuit’s capability to produce high-purity lithium carbonate suitable for industrial use, with potential to meet battery-grade specifications through additional refinement.

Ore Reserve Quadruples for Rhyolite Ridge Project; Reaffirms Robust Project Economics
Ioneer Ltd (ASX: INR, Nasdaq: IONR) (Ioneer) is pleased to announce a 308% upgrade to the Ore Reserve estimate for its 100%-owned Rhyolite Ridge Lithium-Boron Project (‘Rhyolite Ridge’ or the ‘Project’) in Nevada, USA, alongside updated Project economics.
- Rhyolite Ridge Ore Reserve more than quadrupled from 60 million tonnes in 2020 to 247 million tonnes, delivering a mine life of 95 years
- Ore Reserve now contains a total of 1.92 Mt of lithium carbonate equivalent and 7.68 Mt of boric acid equivalent
- Underpinning plans for a large, long-life, low-cost expandable operation, producing lithium carbonate, boric acid and then battery-grade lithium hydroxide
- Stable co-product - boric acid accounts for an average 25% of annual revenue in the first 25 years; helping ensure positive EBITDA at low lithium prices and EBITDA margin of 65.7% based on average production over first 25 years
- All-in sustaining cash cost of US$5,745 per metric tonne lithium carbonate equivalent places the Rhyolite Ridge Project in the bottom of the global lithium cost curve
- Compelling Project economics with an after-tax NPV of US$1.367 billion, and an unlevered, after-tax internal rate of return (IRR) of 14.5%
The Ore Reserve has increased by 186.6 million tonnes (Mt) and approximately 48% of the Mineral Resource has been converted into Reserve, now estimated at:
- 246.6 Mt at 1,464 ppm lithium and 5,444 ppm boron
- Containing 1.92 Mt of Lithium Carbonate Equivalent (LCE) and 7.68 Mt of Boric Acid Equivalent (BAE)
“Today’s updated Reserve and Mine Plan reinforces the importance of Rhyolite Ridge’s remarkable mineralogy. Our Ore Reserve estimate of 247 Mt containing a total of 1.92 Mt LCE and 7.68 Mt BAE make it the largest lithium-boron Reserve in the world,” said Bernard Rowe, Managing Director, Ioneer. “It allows Ioneer to match prevailing market conditions and blend or prioritise ore to produce a valuable boric acid co- product, whose market is uncorrelated with the Project’s primary lithium product. No other lithium project offers this level of flexibility and economic advantage. In periods of low cycle lithium pricing, like today, we plan to prioritize the high-boron ore production to optimize the relative proportion of total revenue derived from boric acid.”
By prioritising High-Boron (Hi-B) ore in the first 25 years of production, the Project is poised to produce an average of ~19,200 tonnes per annum (tpa) of LCE, and 116,400 tpa of boric acid (see Table 1).
The updated Ore Reserve estimate, 95-year mine plan for stage one operations, and Project economics reaffirms Rhyolite Ridge as a highly attractive global Project to produce lithium carbonate, lithium hydroxide and boric acid. The updated findings position Ioneer, on an LCE basis, in the lowest cost quartile for lithium production globally with an estimated all-in sustaining cash cost to produce battery grade lithium hydroxide of US$5,745 and a cash cost of C1 $3,858 per tonne net of expected boric acid revenue in the first 25 years.
The Project has a stable overall operating cost structure to produce lithium carbonate and battery grade lithium hydroxide due to the scale and reliability of its boric acid credit. Boron remains one of the most stable natural resource commodities over many decades.
Ioneer has refined Project plans over the past four years and updates now include an Association for the Advancement of Cost Engineering (AACE) Class 2 capital cost estimate (-10%, +15%) with approximately 70% of the Project’s engineering complete. As a result of this and other engineering work including RAM analysis and detailed engineering design, Ioneer has adopted a more conservative approach to plant availability, equipment downtime and maintenance strategies. While this approach reduces bottom line economics, the Company believes it is appropriate for a Project of this type and scale.
The Company now estimates total capital expenditure to complete the Project will be US$1,667.9 million, including a 10% contingency.
