A significant bulk sampling and test pits program has recently been completed at Impact Minerals Limited’s (ASX:IPT) flagship Lake Hope High Purity Alumina (HPA) project located 500 km east of Perth in Western Australia. The program is a critical component of the Pre-Feasibility Study on Lake Hope, which is currently underway following a positive Scoping Study on the project that indicated the project may be the lowest-cost producer of HPA globally by a significant margin (ASX Release 9th November 2023).
Impact has the right to earn an 80% interest in the Lake Hope project by completing the Pre-feasibility Study (ASX Release 21st March 2023).
A total of 5.5 tonnes of material was collected from twenty-five bulk samples taken from test pits across West Lake and East Lake, which host the alumina deposit at Lake Hope. The deposit contains a resource of 3.5 million tonnes at 25.1% alumina (Al2O3) for a contained 880,000 tonnes of alumina, of which about 88%, or about 775,000 tonnes of alumina, is in the higher confidence Indicated Resource category (ASX Release 19th June 2023).
Impact confirms that no new information exists, and all modifying factors remain the same as at the time of the first publication of the resource.
In addition, earthworks for access tracks and drill pads for water bores for groundwater monitoring were also completed.
Managing Director Dr Mike Jones said: “This bulk sampling program marks another significant milestone in our journey towards the production of High Purity Alumina (HPA) from Lake Hope and caps off a very busy and successful nine months since acquiring the rights for this exceptional project.
In that time, we have completed a maiden resource statement, obtained heritage clearance from the Ngadju First Nations people, completed most of the first phase of metallurgical test work using the unique Playa One sulphate process, and completed a Scoping Study. The results of that study were outstanding and demonstrated the potential of Lake Hope to produce HPA at a cost much less than any other supplier globally, and this has given us the confidence to progress the pre-feasibility study aggressively. The bulk samples will set us up for the forthcoming stages of development, which will include the commissioning of a mini-pilot plant once the initial test work is completed.
Our focus for 2024 will be to complete the PFS, which will include setting up the mini-pilot plant and, in particular, producing HPA in bulk for potential customers and off-take partners. As part of this strategy, we have already started reaching out to key groups in the battery and LED market, and the demand is there. We look forward to a watershed year for Lake Hope, Impact and its shareholders”.
About the Bulk Sampling and Earthworks Program
Impact commissioned Pinnacle Site Services to undertake an earthwork and bulk sampling program. A backhoe was used to refurbish the existing access track to the site, construct access tracks to the lakes and a drill pad for a water monitoring bore.
A total of 5.5 tonnes of aluminous mud was collected from 25 pits, 13 from West Lake and 12 from East Lake (Table 1 and Figure 1). Ground conditions during excavation of the lake surfaces were excellent, with the mud hard, dry and easily dug. Groundwater was absent in most excavations, likely due to the dry summer conditions, which emulate the three-yearly summer mining campaigns proposed in the Scoping Study (ASX Release 9th November 2023).
A number of the sample sites were left open for geotechnical studies on the performance of the mud with respect to slope stability and groundwater levels, both of which will be monitored over the next 12 months before rehabilitation.
These ground-disturbing activities were enabled after successful Aboriginal Culture and Archaeological surveys were completed in July with the Ngadju Native Title group (ASX Release 27th July 2023). The survey identified no sites of cultural or archaeological significance, which is critical for Impact lodging a Mining Lease Application.
Update on the Pre-Feasibility Study
Impact has continued to progress the Preliminary Feasibility Study on Lake Hope.
The Baseline Flora and Fauna Survey data collection process is complete, with a final report due early in Q1 2024. Once received, the results will be used to finalise the location of mining lease boundaries and infrastructure corridors. A Mineralisation Report, a critical requirement of a mining lease application, has been completed, and the application will be lodged as soon as practicable in Q1 2024.
The metallurgical test work has progressed to final purification testing, with preliminary results expected in January 2024 (Stages 4 and 5 of the Playa One Sulphate Process, ASX Release 18th October 2023). Design of the by-product circuit and re-design of acid and reagent handling strategy is underway to investigate options for reduced capital and energy costs. A comprehensive test work regime is under design to inform a mini-pilot plant configuration, with quotes being sought.

Impact Minerals Limited
Investor Insight
With a mining lease application underway and a scoping study that shows excellent economics, Impact Minerals’ game-changing, advanced Lake Hope high-purity alumina project makes for a compelling investment case.
Overview
Impact Minerals (ASX:IPT) is an exploration and development mining company focused on discovering and developing new resource projects within Australia. Lake Hope, a transformational acquisition by the company and its current flagship asset, is a high-purity alumina (HPA) project in Impact’s home territory of Western Australia, a tier-one jurisdiction.
This advanced-stage project allows the company to fast-track the asset toward development, firmly establishing the company on the road to production and increasing shareholder value.
HPA is a high-value product with various uses in several industries that are key to the transition to a low-carbon world. It is mainly used in LED lighting, micro-LED screens, and ceramic-coated separators in lithium-ion batteries. Both these markets are forecast to grow dramatically over the next decade, and a looming supply shortage is predicted for 2026.
HPA is also necessary for producing synthetic sapphire and scratch-resistant glass. With these ever-widening applications for HPA, demand for this resource is expected to grow from US$3.18 billion to US$12.21 billion by 2030 with a compounded annual growth rate of about 20 percent.
Lake Hope is the company’s current focus as it moves towards production, and where a very shallow, high-grade resource of HPA precursor material has been identified in the top two meters of a dry salt lake. The deposit has unique physical and chemical properties that will allow for inexpensive digging and mining, with transportation to a processing facility off-site in an established industrial area. This will accelerate the approvals processes required to get into production.
With a mining lease application pending, Impact aims to bring Lake Hope, which contains almost 1 million tons of potential HPA, into production when the forecast average price for 4N HPA (99.99 percent Al2O3) and related products is about US$20,000 per ton. The ‘4N’ designation indicates the purity grade, making it suitable for high-tech end uses.
Outstanding economics from the latest scoping study released by the company shows Lake Hope’s potential to be the lowest-cost producer of HPA globally by up to 50 percent.
Lake Hope has a maiden mineral resource estimate (MRE) of 3.5 million tons at 25.1 percent alumina (Al2O3) for a contained 880,000 tons of alumina. The company also received heritage clearances for the entire Lake Hope deposit further de-risking the project and providing another critical component in the company’s application for a mining lease.
Impact completed a bulk sampling and test pits program at the Lake Hope project in December 2023, and later reached a key milestone by producing HPA greater than 99.99 percent (4N) purity from the metallurgical processing of lake clays acquired from Lake Hope.
In February 2024, a new proprietary metallurgical process for producing HPA from the lake clays was identified. Impact produced 99.99 percent (4N) Al2O3 from a low-temperature leach (LTL) process. The LTL process may lower the capital and operating costs to produce HPA compared to the sulphate process which underpinned the recent scoping study. The LTL process will be included in the ongoing pre-feasibility study in parallel with the sulphate process at marginal extra cost to determine the best processing route to HPA. The PFS is due to be completed in late 2024.
A comparison of the LTL process and the sulphate process
The company is well funded to finance the pre-feasibility study at the Lake Hope High Purity Alumina project and exploration activities at the Arkun battery minerals project.
Impact Minerals has been awarded a $2.87 million grant for the commercialisation of its innovative process to produce High Purity Alumina (HPA) from the Lake Hope deposit. The grant is under the Federal Government’s Cooperative Research Centres Projects (CRC-P) program which fosters short-term, industry-led research collaborations. The grant is part of an estimated $6.4 million research and development project to be completed within three years and designed to provide Impact with the relevant information required to complete a definitive feasibility. A key component of the grant funding will be to construct a pilot plant, which is a key goal for 2025, and this will provide consistent material for off-take and qualification trials.
Impact Minerals was also one of the inaugural cohort of seven companies selected to be part of the prestigious BHP Xplor program. BHP Xplor, an accelerator program introduced by BHP in August 2022, is designed to help provide participants with the opportunity to accelerate their growth and the potential to establish a long-term partnership with BHP and its global network of partners.
The BHP Xplor funding was used to identify new target areas for copper and other energy metals around the Broken Hill area in New South Wales, eastern Australia, where Impact has been quietly adding to its ground position for several years.
Additionally, the company is exploring its large Arkun battery metals project, also in Western Australia which covers nearly 2,900 square kilometres. Three new exploration licence applications were submitted recently immediately north of the Arkun project along trend from the recently discovered REE soil geochemistry anomalies at Hyperion, Swordfish and Horseshoe, and the Caligula copper anomaly. These anomalies require drill testing which will occur in 2024 and is an exciting development in the emerging mineral province of southwest WA.
A strong management team with over 50 years of combined industry experience leads the company. With a mining and exploration geology degree, Dr. Mike Jones, managing director, launched a long career consulting and leading mining organizations. Peter Unsworth, the non-executive chairman, has more than 35 years of experience in multiple financial sectors, such as securities industries and wealth management. Paul Ingram, a non-executive director, has led several mining companies since 2003. Impact Minerals has the experience and expertise to lead the company to success.

Overview
Founded in 2009 and publicly listed in 2011, Angkor Resources (TSXV:ANK,OTCQB:ANKOF) has built a unique dual-focused enterprise across energy and minerals in Asia and North America.
On the energy side, the company is advancing acquisition of cash flow through oil production and carbon capture in Canada, and is poised for transformational growth through the first-ever onshore oil and gas exploration program in Cambodia. Its Canadian subsidiary, EnerCam Exploration, is already generating revenue from oil production, water disposal and gas processing, while also implementing carbon gas capture and conversion solutions for provincial markets. In Southeast Asia, Angkor’s Cambodian subsidiary, EnerCam Resources, is spearheading a national-scale initiative to bring Cambodia its first domestic hydrocarbon energy, with exploration activities underway on the company’s Block VIII concession.
On the mineral side, Angkor has positioned itself as a first-mover in Cambodia’s underexplored mineral belts, holding licenses at Andong Meas and Andong Bor. These projects target both precious and base metals, with copper porphyry systems and high-grade gold mineralization now confirmed through exploration results.
Angkor’s strategy is designed to mitigate shareholder risk by diversifying revenue streams, blending recurring Canadian cash flow with high-impact exploration upside in Cambodia. The company’s management emphasizes hydrocarbons and copper as priorities, noting the potential value of 25 million recoverable barrels in Cambodia alongside significant copper-gold discoveries.
Key Projects
Onshore Cambodia – Block VIII Oil & Gas Concession
Angkor’s flagship asset is Block VIII, a 4,300 sq km oil and gas concession in Cambodia’s underexplored onshore sedimentary basin. The license, structured under a 30-year Production Sharing Agreement with renewal options, represents the first onshore hydrocarbon exploration license in the country. Geoscientific studies conducted by Danish, Canadian and European experts have identified strong indications of a foreland basin system and rift formations with significant petroleum potential. Over 21 natural oil seeps have been mapped and testing of the seeps by Schlumberger confirms the presence of hydrocarbons. Gas showings are also evident across the block.
The block is ideally located adjacent to export infrastructure, close to port with highway access to Phnom Penh and proximity to a deepwater port. Cambodia currently imports all of its petroleum products, making Block VIII strategically important both nationally and regionally. EnerCam, Angkor’s subsidiary, is implementing Cambodia’s first onshore 2D EnviroVibe seismic program, designed to minimize environmental footprint while mapping structural traps and stratigraphic features.
Technical projections suggest that once commercial quantity of recoverable hydrocarbons is proven, Block VIII could host Cambodia’s first onshore oil production. Angkor’s phased development plan includes completing seismic interpretation, definition of drill targets or additional 3D seismic followed by stratigraphic test wells and eventual development drilling. This project is expected to be the company’s most significant value driver and is prioritized as its number one corporate focus.
Canadian Energy & Carbon Capture – EnerCam Exploration
In Canada, Angkor operates through EnerCam Exploration Canada, which is a 40 percent interest holder in oil production and carbon solutions across 30 well sites spanning 516 hectares in Saskatchewan. These wells, shut in since 2018 due to low oil prices and mismanagement by previous operators, have been systematically refurbished and restarted. EnerCam participates in the full production cycle, including oil recovery, water separation and gas handling.
A key milestone was the acquisition of the pipeline network and compressor station, which resolved historical venting issues and allowed EnerCam to capture associated gas. This gas is converted into natural gas energy and sold into provincial markets. Angkor’s Canadian revenue streams also include water disposal fees, gas plant operations, and oil production revenues, supplemented by ongoing carbon capture and enhanced recovery of water conversion and injection wells projects.
Angkor holds a 40 percent interest in oil and gas production ventures in Saskatchewan, ensuring a recurring revenue stream. This platform not only offsets G&A costs but also provides a foundation for emission control and potential for further gas capture with surrounding producers in the area.
Cambodia Mineral Properties – Copper and Gold Portfolio
Through its subsidiary Angkor Gold Cambodia, the company holds a strategic portfolio of copper and gold assets in prospective belts. These licenses include Andong Bor and Andong Meas.
The Andong Bor license has emerged as a cornerstone of Angkor’s mineral portfolio. In June 2025, the company confirmed the presence of a copper-gold porphyry system, the first discovery of its kind in Cambodia. This breakthrough positions the project as a potential district-scale copper-gold system. Further drilling is expected to test depth extensions and delineate mineralized zones.
At the Andong Meas license, exploration has revealed high-grade gold mineralization, with surface samples returning assays up to 70 grams per ton (g/t) gold across a 0.8 km by 1.5 km area. This anomaly remains largely untested by drilling and represents a significant near-term target for resource expansion.

Prince Silver: Advancing the Large-scale Prince Silver Project in Nevada
Prince Silver (CSE:PRNC,OTC:HWTNF) is a Vancouver-based exploration company advancing the Prince Silver project in southeastern Nevada. In July 2025, the company completed the transformational acquisition of Stampede Metals Corporation and rebranded from Hawthorn Resources to Prince Silver Corp. The flagship Prince project is a district-scale, past-producing silver-gold-zinc-manganese carbonate replacement system, historically mined for silver and base metals in the early to mid-1900s.
Aerial view of the Prince silver projectFully funded and technically refreshed, the company’s near-term priority is to validate and build upon the 129 historic drill holes (over 16,600 m) completed on the property, with the goal of converting the large JORC-compliant exploration target into a maiden NI 43-101 mineral resource.
A drill program is scheduled to begin in early September 2025, targeting the validation of legacy data, step-outs along mineralized trends, and continuity across the deposit’s multiple mantos, veins, and breccia zones. In parallel, the company will undertake metallurgical test work, geophysical refinement, and updated geological modeling to support a modern pit-constrained resource and underpin a longer-term development strategy.
Company Highlights
- Flagship project: 100 percent ownership of the historic Prince silver mine in Lincoln County, Nevada, an open, near-surface silver-gold-zinc carbonate replacement deposit with a 25 to 43 Mt exploration target and strong historic grades.
- The company’s second project, Stampede Gap, is about 15 km north west of the Prince mine. Stampede Gap is a large porphyry copper-gold-molybdenum with an extensive alteration zone that presents a deep seated exploration target.
- Clean corporate reset: Hawthorn Resources completed the Stampede Metals acquisition and re-listed as Prince Silver Corp. on July 11, 2025, issuing 15 million shares for the acquisition and raising ~C$4 million in gross proceeds to fund drilling.
- Fully funded summer drill program: ~6,500-m reverse-circulation set to begin early Sept 2025 to validate historic holes and step out along strike/dip to expand known mineralization and potential resources. .
- Tight share structure: 45.9 million shares outstanding post-financing; Stampede shareholders voluntarily locked-up for 12 months.
- Experienced, hands-on leadership: President Ralph Shearing, plus new directors Robert Wrixon and Darrell Rader, add mine-building, corporate and capital-markets depth to the company’s leadership team.
