Caprock Mining Corp. (CSE: CAPR) ("Caprock" or the "Company") is pleased to announce high-grade lithium assay results from samples obtained 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. Assay highlights from the sampling program are provided in Figure 1 below.

Caprock's CEO Mr. Vishal Gupta states: "Today's assay results confirm our assessment that Ackley has the potential to host significant lithium mineralization. While these samples were obtained from in-situ zinnwaldite boulders and sub-crop during a first-pass prospecting program in a very small portion of the Main Block called the 'Deer Pond' area, we are already starting to see the delineation of a mineralized trend within the greisened rock at Deer Pond. On the basis of these high-grade assays, Caprock's technical team plans to continue its aggressive exploration of the Main Block in the coming weeks."
Field observations indicate that the sampled zinnwaldite boulders and sub-crop occur in close proximity to the large greisen zone at Deer Pond, however the mineralization appears to be more spatially related to the fine-grained Devonian-aged Ackley granite. This provides Caprock's technical team a prospective area spanning several square kilometres within the Main Block where additional lithium-bearing mineralization could be uncovered. The Company awaits additional confirmation of the zinnwaldite mineralization through detailed petrographic analysis of field samples. Highlighted sample locations are illustrated in Figure 2 below.

Procedures Utilized for Assay Analysis
The samples were submitted to the AGAT Laboratories Ltd. (AGAT) laboratory in St John's, Newfoundland and internally couriered to the AGAT Mining Geochemistry Laboratory in Mississauga, Ontario for sample preparation and assay testing using Sodium Peroxide Fusion (lithium) with inductively coupled plasma - optical emission spectrometry (ICP-OES) and inductively coupled plasma - mass spectrometry (ICP-MS) finish for multi-element analysis. AGAT is independent of Caprock and is accredited to ISO/IEC 17025:2017 standards.
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.

Beneficiation Delivers 4,480ppm Lithium Clay Concentrate at Red Mountain Project, USA
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
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.
