Forrestania Resources Limited (ASX:FRS) (Forrestania or the Company), is pleased to provide an update on activities at its Eastern Goldfields project area located north of Coolgardie and north of Kalgoorlie, around the gold mining districts of Leonora, Coolgardie and Menzies (see figure 1). The Eastern Goldfields project area comprises eighteen tenements (eight ELs and ten EL applications) that are strategically located over areas that the Company believes are highly prospective for multi-commodities, particularly lithium, gold, REE and copper.
Highlights:
- Fieldwork underway on highly prospective Eastern Goldfields tenements, following recently announced agreement with Outback Minerals Pty Ltd1.
- Multiple outcropping pegmatites, up to ~100m in strike length, mapped at the Breakaway Dam / Alexandra Bore project area (E29/1037), contiguous to Forrestania’s existing tenement position. The recently acquired tenements have never previously been explored for lithium.
- Outcropping pegmatites also mapped at the Bonnie Vale project area (E15/1632), near Coolgardie.
- Mapping and sampling will continue to assist in defining targets for a maiden drilling programme.
Forrestania Resources’ Managing Director Michael Anderson commented:
“The rationale for entering into the option agreement with Outback Minerals already appears to be justified. The confirmed presence of multiple pegmatite outcrops, some up to ~100m in strike length, provides us with additional confidence in the discovery potential on these tenements. We are prioritising our activities to prepare for a maiden drilling programme, as soon as possible.”
Discussion:
The Company has recently completed a mapping and reconnaissance field trip to the newly acquired Eastern Goldfields tenements. The focus of the trip was to further enhance the Company’s geological understanding of the project areas, as well as to further assess the potential for lithium mineralisation.
The newly acquired tenements (Alexandra Bore / Breakaway Dam project (E29/1037 and E29/1036) have never previously been explored for their lithium potential, with previous historic exploration instead focussed on copper, gold and nickel, despite the known presence of pegmatites.
The Bonnie Vale project area (E15/1534 and E15/1632) has also never been explored for its lithium potential, with previous explorers focussing on the tenement’s gold prospectivity.
Mapping and field work is on-going, but the company is pleased to announce that additional pegmatites have been mapped at both project areas, specifically on E29/1037 and E15/1632.

The Company recently completed a mapping and reconnaissance field trip to the newly acquired Alexandra Bore / Breakaway Dam project area (see Figure 2).
Pegmatites have previously been mapped by the company at the Alexandra Bore / Breakaway Dam project areas1 and ongoing field reconnaissance is currently underway.
Significantly, additional pegmatite outcrops have recently been mapped at surface by Company geologists, with outcropping pegmatites ranging from ~43m and up to ~100m in strike length (see Figures 3, 4, 5 and 6). These pegmatites were located approximately 300m apart and have never previously been tested for lithium or LCT pathfinder minerals. Indeed, the Alexandra Bore / Breakaway Dam project area has only previously been explored for copper and gold1 and the potential for lithium mineralisation has yet to be fully evaluated. Importantly, these outcrops are all located within the mapped greenstone or close to greenstone/granite contacts (as interpreted by GSWA).

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.

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.
