Large Jorc Exploration Target Range For Colina Confirmed
Latin Resources Limited (ASX: LRS) (“Latin” or “the Company”) is pleased to provide the following update on resource definition drilling and other studies currently ongoing at the Company’s 100% owned high-grade Colina Lithium Prospect (“Colina”) (Appendix 1).
HIGHLIGHTS
- Maiden independent JORC Indicated and Inferred Mineral Resource Estimate (“MRE”) for the Colina Lithium Deposit of 13.3Mt @ 1.2% Li2O reported above a cut-off of 0.5% Li2O (2.08Mt Indicated and 11.17Mt Inferred).
- Significant upside growth potential identified at Colina, with SGS confirming an independent estimated JORC Exploration Target Range ("ETR”).
- Recent drilling at the Colina West prospect, 500m to the west of Colina has confirmed the continuity of the thick high-grade spodumene pegmatites intersected in drill hole SADD033, with a further three holes intersecting the newly identified pegmatite swarm, assay results pending.
- Aggressive 65,000m drilling campaign planned for 2023 with the addition of four more drilling rigs for a total of eight on site, this is designed to fast track rapid resource growth at the Colina and Colina West Deposit and underpin a rapid move towards potential future development.
- Preliminary Economic Assessment (PEA) is well under way to allow fast tracking of DFS in 2023.
In October, the Company commissioned Toronto based independent resource consultants SGS Geological Services (“SGS”), to undertake the estimation of a JORC Mineral Resource Estimate (“MRE”), and a wider Exploration Target Range (“ETR”) for the Company’s Colina Lithium Deposit.
SGS, working closely with the Company’s geological team have confirmed the presence of a series of moderately east dipping pegmatite bodies, extending from near surface to a depth of over 350m. These pegmatites remain open along strike to the north and south, and at depth.
Based on assay results from a total of 47 diamond drill holes for some 10,528 m of drilling, SGS has independently estimated the maiden Mineral Resource for the Colina Deposit in only 10 months since the commencement of drilling in early 2022. Of the 57 diamond drill holes completed at the cut-off date, 47 drill holes have assays results used for the MRE to produce a JORC Indicated and Inferred resource estimate of 13.3mt @1.2% Li2O (2.08Mt Indicated and 11.17Mt Inferred).
SGS has also estimated a JORC ETR of 13.5 – 22 Mt with a grade range of 1.2 – 1.5% Li2O for the Colina Deposit based on data from all the available 57 diamond drill holes. The current interpretation indicates that that the modelled pegmatites potentially increase in both thickness and grade with depth, additional drilling is required to confirm these observations.
*The potential quantity and grade of the lithium mineralisation at the wider Colina project is conceptual in nature, there has been insufficient exploration to estimate a Mineral Resources and it is uncertain if further exploration will confirm the target ranges.

Latin Resources’ Executive Director, Chris Gale, commented:
“The maiden JORC Resource is a significant milestone for Latin Resources. We are very excited by the immense upside in the potential resource size as we plan to drill 65,000 metres through 2023. The exploration team led by Tony Greenaway and Pedro Fonseca in Brazil have accomplished a fantastic result for the company in a short period of time.
“The company is now very focused to continue to grow our lithium resource significantly over the next six months, as well as complete our feasibility studies to fast track development of a very special lithium project in Brazil.”
Latin Resources’ Geology Manager, Tony Greenaway, commented:
“We are all extremely pleased with the outcome of our maiden MRE process; the declaration of a 13.3 million tonne resources at a grade of 1.2% Li2O, in just 10 months from the completion of our first drillhole is an outstanding achievement. The MRE proves that the Colina Deposit is a significant discovery and will be the platform on which the Company will grow its resource inventory through further drilling in 2023.
“The potential growth for the Colina Deposit is highlighted by the independent exploration target by SGS, which has an upper range of 22 million tonnes at Colina3. This target range does not consider the additional pegmatites discovered at Colina West, where we believe we will be able to add significantly to the resource inventory with more drilling.
“With eight drill rigs scheduled to be on site from mid-January 2023, we will be aggressively drilling throughout the year, specifically targeting Colina West with resource definition drilling, the Colina Deposit itself with resource infill drilling, Colina South and the Salinas South prospect areas with reconnaissance exploration drilling, where we hope to have our next discovery.”

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.

Investor Insight
Leveraging early-stage land acquisition, accelerated drilling and a strong strategic partnership, Lithium Africa delivers maximum exploration efficiency, capital leverage and de-risked lithium discovery upside at scale.
Overview
Lithium Africa is an exploration company purpose-built to capitalize on the next cycle of lithium demand. Its strategic mission is to discover, de-risk and monetize Tier 1 lithium assets through data-driven targeting, aggressive fieldwork and value-driven exits. The company's unique 50/50 joint venture with Ganfeng Lithium is the cornerstone of its strategy, providing both financial leverage and industrial alignment at the earliest stages of project development.
Africa remains largely underexplored for lithium despite sharing geological similarities with major hardrock lithium belts in Canada and Australia. 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.

- 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.

Rio Tinto Partners with Codelco to Develop Lithium Project in Chile
Rio Tinto (ASX:RIO,NYSE:RIO,LSE:RIO)said on Monday (May 19) that it has signed binding agreements with Corporación Nacional Del Cobre de Chile (Codelco) to develop and operate a high-grade lithium project.
The asset is located in the Salar de Maricunga, a large lithium-containing resource base in Atacama, Chile. Its brine is said to have one of the highest average grades of lithium content in the world.
According to Rio Tinto, it will acquire a 49.99 percent interest in the company Salar de Maricunga, through which Codelco holds its licenses and mining concessions related to the resource base.
Codelco is a state-owned firm formed in 1976. Its full name translates to “National Copper Corporation of Chile.”
“We are honoured to be chosen as Codelco’s partner to deliver a world-class project using Direct Lithium Extraction technology in the Salar de Maricunga, leveraging our expertise as a leading producer of lithium for the global market,” said Rio Tinto Chief Executive Jakob Stausholm. “Developing this significant lithium resource will deliver further value-adding growth in our portfolio of critical minerals essential for the energy transition.”
In 2023, Rio and Codelco entered a joint venture for the exploration of Nuevo Cobre, situated within the Potrerillos mining district, also in Atacama. Codelco owns about 43 percent of Nuevo Cobre, while Rio Tinto owns about 58 percent.
For the Salar de Maricunga partnership, Rio will invest AU$350 million in initial funding for additional studies and resource analysis that will assist in creating a final investment decision.
Once a decision is made, AU$500 million will be dedicated toward construction costs. Another AU$50 million will be allocated should the venture deliver its first lithium target by the end of 2030.
The new partnership with Codelco forms part of Rio Tinto's long-term lithium plan, which includes a production goal of over 200,000 metric tons of lithium carbonate equivalent annually by 2028.
The company recently completed its acquisition of Arcadium Lithium, making it the world's third top lithium producer.
Subject to regulatory approvals and the satisfaction of customary conditions, the Salar de Maricunga transaction is expected to close by the end of the first quarter of 2026.
