Caprock Mining Corp. (CSE: CAPR) ("Caprock" or the "Company") is pleased to announce that its technical team has discovered the presence of zinnwaldite, an extraordinary lithium-bearing mineral, during a recently concluded prospecting and sampling program on the eastern-most claim block (the "Main Claim Block") at its Ackley Lithium-Tin-Molybdenum-REEs property ("Ackley", or the "Property") located in south-eastern Newfoundland, for which the Company has an option to acquire a 100% interest.
Caprock's CEO Mr. Vishal Gupta states: "Historical work at Ackley returned assays of up to 0.91% lithium oxide, however the specific lithium-bearing mineral was never identified until an internal assessment of recently obtained samples by Caprock's technical team. We are very excited by this discovery, since we believe that it is much easier and a lot less capital-intensive to produce lithium hydroxide from zinnwaldite than from the highly sought-after mineral, spodumene."
Mr. Gupta goes on to say, "Zinnwaldite is being successfully mined and processed at the Zinnwald Lithium project in Germany, and its presence has only been documented a handful of times in Canada, previously. While it is still early days in our exploration work at Ackley, initial prospecting work indicates a potential for extensive zinnwaldite mineralization on the Property related to the large 'greisen' zone that resides at the contact between the Devonian-aged granite complex, and the Proterozoic metasediments and volcanics over which the Ackley claim blocks lie."
Assay results from grab samples taken during recent field work will be published in subsequent press releases. The Company also awaits additional confirmation of the zinnwaldite mineralization through detailed petrographic analysis of the grab samples.
Additional Information About Zinnwaldite
Zinnwaldite is a potassium-lithium-iron-aluminum-silicate-hydroxide-fluoride phyllosilicate mineral within the mica group that typically occurs in greisens, pegmatites and quartz veins, and is often associated with tin ore deposits.
In general, zinnwaldite ore is the least energy- and capital-intensive hard rock mining alternative to a lithium-brine operation with respect to the production of lithium hydroxide, especially when compared to spodumene ore. Whereas spodumene concentrate must undergo two separate "high temperature" roast cycles prior to the production of lithium hydroxide, zinnwaldite concentrate only has to undergo a single "medium temperature" roast cycle in order to produce lithium hydroxide.
Additionally, unlike spodumene which has a tendency to lose its lithium content when exposed to ambient weather conditions, zinnwaldite is not subject to weather conditions as a means of production, which allows for greater certainty of supply and control of production.

About the Ackley Property
Ackley comprises three claim blocks that collectively span an area of 4,550 hectares located less than two hours' drive from St. John's. The claim blocks overlie portions of the contact zone of a large Devonian-aged granite complex with Proterozoic metasediments and volcanics, parts of which are "greisened", or hydrothermally altered, that is similar in age and lithology to the Mount Pleasant deposit in New Brunswick and the East Kemptville deposit in Nova Scotia. Limited historical exploration work across the Main Claim Block by companies including Esso Minerals, American Zinc, Inco and others, discovered occurrences and anomalies of lithium, tin, molybdenum, tungsten and REEs.
Recent magnetometer survey work over part of the Main Claim Block indicates that the altered contact zone may be extensive, covering several square kilometres. Recent limited prospect sampling and historical Esso trenches across the Main claim block returned assays of up to 0.91% lithium oxide, 5.0% molybdenum, 0.67% tin and 1-5% fluorine on surface. Newfoundland government survey maps of this region report some of the highest lake sediment values for REEs on the entire island.

Lithium Africa CEO Makes Case for Lithium Investing Amid Bear Market
The CEO of Lithium Africa is making a case for investing in lithium during the current bear market, saying recent moves by major players such as Rio Tinto (ASX:RIO,NYSE:RIO,LSE:RIO) indicate confidence in the market's longer-term potential.
“(Rio Tinto) is the second biggest miner of commodities on the planet. And late last year, they did the Arcadium Lithium transaction, which is the second largest transaction in corporate history, and they've picked lithium," Tyron Breytenbach said during an interview with the Investing News Network.
"Shortly after that, they followed on with a big, multibillion-dollar investment in Chile. Again, the commodity they picked was lithium."
Lithium Africa is advancing a portfolio of lithium exploration assets in Africa, and has established a strategic partnership with Ganfeng Lithium (OTC Pink:GNENF,HKEX:1772), a major producer of lithium battery products.
Breytenbach said Ganfeng sees the company’s potential to make a discovery and become a low-cost source of lithium. In return, Lithium Africa can take advantage of the capital and chemical expertise Ganfeng offers.
“We're planting the seeds now that investors are going to reap when the next (lithium) bull market comes back … And I think when the market comes back, we're going to be the leader in Africa,” he said.

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.”

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.
