Drilling at the new Dog-Leg target increases the Mineral Resource Estimate for the Ewoyaa Lithium Project to 36.8Mt at 1.24% Li2O
Atlantic Lithium Limited (AIM: ALL, ASX: A11, OTCQX: ALLIF, “Atlantic Lithium” or the “Company”), the African-focused lithium exploration and development company targeting to deliver Ghana’s first lithium mine, is pleased to announce an increase to the JORC (2012) compliant Mineral Resource Estimate (“MRE” or “Resource”) at the Company’s flagship Ewoyaa Lithium Project (”Ewoyaa” or the “Project”) in Ghana, West Africa.
Highlights:
- Total Mineral Resource Estimate for the Company’s flagship Ewoyaa Lithium Project increased to 36.8Mt at 1.24% Li2O, reported in accordance with the JORC Code (2012).
- 81% of the Total Resource now in the higher confidence Measured and Indicated categories (3.7Mt at 1.37% in the Measured category, 26.1Mt at 1.24% in the Indicated category and 7.0Mt @ 1.15% Li₂O in the Inferred category).
- MRE increase follows targeted drilling programme, undertaken in 2023 and H1 2024, comprising sterilisation drilling to support the plant and haul road design and resource conversion drilling, converting Inferred resources to Indicated and Measured resources, to provide mine plan optionality; new Dog-Leg target identified through this process.
- Drilling subsequently undertaken on the Dog-Leg target, where the Company has identified a shallow-dipping, near-surface mineralised pegmatite body with true thickness up to 35m, which contributed 890,892 tonnes of the Resource increase to 36.8Mt at 1.24% Li2O.
- Potential to grow the Resource further; step-out drilling planned at five priority deposits and one new exploration target identified for initial reverse circulation (“RC”) evaluation.
Commenting, Neil Herbert, Executive Chairman of Atlantic Lithium, said:
“We are pleased to report an increase in the Mineral Resource for the Ewoyaa Lithium Project to 36.8Mt at 1.24% Li2O, which reaffirms Ewoyaa’s status as one of the leading hard rock lithium projects.
“The increase follows the limited drilling programme completed recently, which was focused on supporting our mine planning activities rather than expanding the resource base, but through which we identified the Dog-Leg target, which has added near-surface tonnes to the Ewoyaa Resource. We are pleased to see this lucky strike at Dog- Leg contributing an additional circa 891,000 tonnes to the enlarged 36.8Mt at 1.24% Li2O Resource.
“While our current focus remains firmly on advancing Ewoyaa towards shovel-readiness, we recognise the significant potential across our exploration portfolio to increase the Resource further.”
Mineral Resource Estimate Upgrade
An upgraded MRE of 36.8Mt at 1.24% Li2O was completed for the Ewoyaa deposit and surrounding pegmatites; collectively termed the “Ewoyaa Lithium Project”.
The MRE increase follows a targeted drilling programme aimed at supporting the mine build activities at the Project. This comprised sterilisation drilling to support the plant and haul road design and resource conversion drilling, aimed at converting Inferred resources to Indicated and Measured, to provide mine plan optionality. The drilling programme resulted in the combined Measured and Indicated resource increasing to 81% of the Total Mineral Resource (to 29.8 Mt at 1.26% Li2O).
During drilling programme, the Dog-Leg target was identified, with prioritised drilling subsequently undertaken, which returned multiple broad and high-grade intersections, from which the Company has identified a shallow-dipping, near- surface mineralised pegmatite body with true thickness up to 35m. The Dog-Leg target contributed 890,892 tonnes, comprising 332,100 tonnes at 1.01% Li2O Indicated and 558,792 tonnes at 1.13% Li2O Inferred, of the increase in resources to 36.8Mt at 1.24% Li2O.
The Mineral Resource is based on 168,015m of drilling completed at the Project to date, inclusive of infill and extensional drilling undertaken since the February 2023 MRE reported by the Company, comprising 148,865m of reverse circulation (“RC”), 12,639m of diamond core (“DD”), 5,311m of reverse circulation with diamond tail (“RCD”) and 1,200m of reverse circulation hydrology holes (“RCH”).
The MRE includes a total of 3.7Mt at 1.37% Li2O in the Measured category, 26.1Mt at 1.24% Li2O in the Indicated category and 7.0Mt at 1.15% Li2O in the Inferred category (refer Table 1). The independent MRE for Ewoyaa was completed by Ashmore Advisory Pty Ltd (“Ashmore”) of Perth, Western Australia, with results tabulated in the Statement of Mineral Resources in Table 1. The Statement of Mineral Resources is reported in line with requirements of the JORC Code (2012) and is therefore suitable for public reporting. High-level Whittle optimisation was completed and demonstrates reasonable prospects for eventual economic extraction.

Investor Insight
Atlantic Lithium is advancing Ghana’s first lithium mine at Ewoyaa, a fully permitted, strategically located project ready to supply global battery markets. With strong local support and a clear path to production, the company is positioned for near-term growth and long-term impact in the energy transition.
Overview
Atlantic Lithium (AIM:ALL,ASX: A11,GSE:ALLGH,OTCQX: ALLIF) is an Africa-focused lithium exploration and development company advancing its flagship Ewoyaa Lithium project through to production as Ghana’s first lithium mine.
Despite its long mining history, favourable regulatory climate and stable political backdrop, Ghana remains largely overlooked as an investment jurisdiction for battery metals. Situated on the West African coast, the country boasts a strong strategic location, between Europe, the Americas and Asia, to serve the global battery metals market. Ghana is also home to an abundance of mineral wealth, with c. 180,000 tonnes of estimated lithium resources.
Atlantic Lithium intends to produce spodumene concentrate capable of conversion to lithium chemicals for use in electric vehicle batteries and energy storage, aiming to support global decarbonisation.
A definitive feasibility study (DFS) released in June 2023 shows that Ewoyaa has demonstrable economic viability, low capital intensity and excellent profitability.
Through simple open-pit mining, three-stage crushing and conventional Dense Medium Separation (DMS) processing, the DFS outlines the production of 3.6 Mt of spodumene concentrate over a 12-year mine life, which will make it one of the largest spodumene mines by production capacity globally.
The Ewoyaa Lithium Project was awarded a Mining Lease in October 2023, an EPA Permit in September 2024, and a Mine Operating Permit in October 2024.
Having secured all of the permits required to begin construction, Atlantic Lithium currently awaits parliamentary ratification of the Ewoyaa Mining Lease, which was issued by the Ministry of Lands and Natural Resources in October 2023.
The JORC mineral resource estimate at Ewoyaa now stands at 36.8 million tons (Mt) at 1.24 percent lithium oxide, 81 of which is now in the higher confidence measured and indicated categories (3.7 Mt at 1.37 percent lithium oxide in the measured category, 26.1 Mt at 1.24 percent lithium oxide in the indicated category, and 7 Mt at 1.15 percent lithium oxide in the Inferred category).
The residents of the project-affected communities in Ghana’s Central Region have voiced their strong support from the advancement of the project towards production.

Project Funding
The development of the project is co-funded under an agreement with NASDAQ and ASX-listed Piedmont Lithium (ASX: PLL), under which Piedmont is required to contribute the first US$70m of Development Costs, as defined in the agreement, as sole funding to complete its earn-in to 50% of Atlantic Lithium's ownership of the project, with all Development Costs and other project expenditure equally shared by both Atlantic Lithium and Piedmont thereafter.
In accordance with the agreement, which is intended to result in the construction of the project and the achievement of initial spodumene production, Piedmont will earn the rights to 50 percent of all spodumene concentrate produced at Ewoyaa at market rates, providing a route to consumers through several major battery manufacturers, including Tesla.
The Minerals Income Investment Fund (MIIF), Ghana’s minerals sovereign wealth fund, has also agreed to invest US$27.9 million at project-level to acquire a 6% contributing interest in the project and Atlantic Lithium’s Ghana Portfolio. The project-level investment represents Stage 2 of its Strategic Investment in the company.
This follows Stage 1 of its Strategic Investment, comprising MIIF’s Subscription for US$5 million Atlantic Lithium shares, which was completed in January 2024, resulting in MIIF becoming a major strategic shareholder in the company.
MIIF’s Strategic Investment is intended to expedite the development of the project towards production.
In addition, noting that Ewoyaa is one of the most advanced undeveloped hard rock lithium projects globally, Atlantic Lithium continues to engage with parties across the battery metals supply chain who express inbound interest in lithium products from Ewoyaa.
In doing so, Atlantic Lithium aims to expedite and de-risk the development of the Project, realise attractive terms for any offtake contracted and secure well-credentialled partners that will support the company's and Ghana's objectives of supplying lithium into the global market.
Ghana
Ghana is a well-established mining region with access to reliable, existing infrastructure and a significant mining workforce. There are currently 16 operating mines in the country.
Already the largest taxpayer and employer in Ghana’s Central Region, Atlantic Lithium is expected to provide direct employment to over 900 personnel at Ewoyaa and, through its community development fund, whereby 1 percent of revenues will be allocated to local initiatives, will deliver long-lasting benefits to the region and Ghana.
Through its proven lithium discovery, exploration and evaluation methodologies, Atlantic Lithium has the potential to capitalise on its extensive exploration portfolio and deliver upon its objectives of becoming a leading producer of lithium in West Africa.

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.

Lithium Africa is the first company to systematically deploy a multi-jurisdictional discovery strategy across the continent – combining top-tier geology with capital efficiency and strategic clarity.
At the heart of Lithium Africa’s model is its joint venture with Ganfeng Lithium, one of the top two lithium chemical producers globally. The 50/50 JV, established in 2023, enables Lithium Africa to double its capital efficiency, with $1 raised equating to $2 spent on exploration. The partnership provides unmatched advantages: access to Ganfeng’s downstream processing know-how, established customer relationships with Tier 1 OEMs, and a long-term offtake framework that allows Lithium Africa to retain flexibility and optionality on any asset monetization.
Lithium Africa does not intend to develop or operate mines. Instead, the business model is designed around efficient land acquisition, aggressive de-risking via trenching, sampling, and early drilling, and ultimately monetizing high-value discoveries through royalties, sales or carried interests. In a down market, the company is actively pursuing counter-cyclical M&A opportunities to acquire stranded or undercapitalized lithium assets. With this strategy, Lithium Africa provides shareholders exposure to world-class discovery upside with significantly reduced financing risk.
Company Highlights
- Exploration-focused Model: Lithium Africa focuses purely on discovery and value creation, with no intention to develop or operate a mine
- Strategic 50/50 JV with Ganfeng Lithium: Doubles exploration spending and provides access to processing expertise and long-term downstream offtake partners.
- Pan-African Footprint: Over 8,000 sq km of tenure across Zimbabwe, Morocco, Mali, Côte d’Ivoire, Guinea, and others – enabling diversification in discovery strategy.
- Contrarian, Countercyclical M&A: Well-capitalized and positioned to roll up distressed lithium juniors during a downcycle
- Rapid Permitting & Scalability: Target jurisdictions offer 3- to 4-year discovery-to-mine timelines versus 10 to 15 years in North America.
- RTO & Listing Expected by August 2025: Tight structure, early institutional support and significant near-term drilling catalysts.
Key Projects
Zimbabwe
Birthday Gift Project (Flagship)
The Birthday Gift project is Lithium Africa’s flagship asset and highest-priority exploration target. Located along a >12 km pegmatite corridor, the project hosts three parallel, flat-lying spodumene-bearing pegmatites within metasediments. Surface trenching has returned multiple significant intercepts, including 100 m, 67 m, and 55 m widths with true thicknesses averaging ~35 m. Rock chip samples from fresh spodumene zones have returned assays as high as 5.25 percent lithium oxide. More than 3,000 geochemical samples have been collected, and a 1,500-meter RC drill program commenced in January 2025 to test a 1,300-meter strike length.
The pegmatites remain open at depth and along strike. SGS South Africa is performing ICP assay analysis, and environmental permitting and trenching on the western trend are ongoing.
The Birthday Gift asset has strong potential to support an inaugural resource estimate by late 2025.
West Africa
Torakoura in Bougouni District, Mali
Lithium Africa controls six highly prospective licenses in Mali, located within the prolific Bougouni Basin, home to Leo Lithium’s Goulamina project, one of the world’s largest spodumene deposits. The Torakoura permit is situated along the same structural corridors and granitic host rocks. Surface exploration has identified spodumene-bearing pegmatites, supported by strong lithium and pathfinder anomalies from historic soil sampling.
Initial drilling at Torakoura began in 2024 but paused for LIBS-to-ICP calibration. A new RC drilling campaign resumed in Q4 2024. These permits offer substantial scale and proximity advantages in a well-established lithium district with proven permitting and development pathways.
Adzopé & Regional Licenses, Côte d’Ivoire
In Côte d’Ivoire, Lithium Africa holds four early-stage but highly promising permits totaling 1,254 sq km. The Adzopé license has returned rock samples with lithium oxide values up to 0.98 percent. Field mapping and lithological sampling have been completed, and a 21,700-meter auger drilling program is planned to refine targets for follow-up RC and core drilling. The region is emerging as a new pegmatite belt in West Africa, and Lithium Africa has first-mover status in building a pipeline of discovery-stage projects.
Kobikoro Project, Guinea
The Kobikoro project in southeastern Guinea consists of four licenses covering 376 sq km in the Archean Kinema-Man domain. This district is part of the underexplored Kissidougou pegmatite belt. Historical stream sediment geochemistry conducted by BRGM highlights multiple anomalous trends in lithium, tantalum and niobium. The standout feature is a 20 km-long lithium-tantalum-niobium anomalous zone aligned with regional structures and underlain by fractionated granite intrusions.
Morocco
Bir El Mami
In 2024, Lithium Africa acquired a 585 sq km, district-scale land package in the Bir El Mami region of Morocco, located on the northern extension of the Tasiast greenstone belt. The project is notable for its spodumene-bearing pegmatites confirmed by surface rock samples, which include lithium values up to 862 parts per million (ppm), and historic soil anomalies up to 363 ppm. The region is emerging as a key lithium district given Morocco’s favorable trade agreements and a growing domestic EV battery manufacturing base. Lithium Africa is currently Morocco’s only major lithium concession holder, and early-stage target identification is underway as of Q1 2025. The company is well positioned to be Morocco’s lithium sector leader and consolidator.
