Impact Minerals Limited (ASX:IPT) is pleased to announce that in collaboration with CPC Engineering and the Mineral Recovery Research Centre (MRRC) at Edith Cowan University, they have been awarded a grant of $2.87 million grant towards the commercialisation of the company’s innovative process to produce High Purity Alumina (HPA) from the Lake Hope deposit located 500 km east of Perth in Western Australia. HPA is on the list of critical minerals for Australia, Europe, and North America.
The grant is provided 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 Study in that time frame. 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’ Managing Director Dr Mike Jones, said, “We are immensely proud to drive this transformative project, which aligns with and advances Australia’s strategic interests in critical minerals. We thank Minister Husic for his personal interest in the project as this federal funding not only underscores the national importance of our work but also enhances our capability to implement world- leading technologies that set new standards in sustainability and efficiency in the mineral sector. Being able to commence work on our pilot plant and the subsequent feasibility studies with the world-leading research of Edith Cowan University and the unique skills and experience of CPC Engineering will position Impact Minerals at the forefront of the global HPA market, ready to meet increasing demands with a sustainably produced, high-quality product. The project is scheduled to advance from initial trials to a definitive study phase swiftly, ensuring timely delivery of HPA and fertilizer samples to potential customers and partners. This grant and likely contributions from the R and D rebate will ensure our next stage of work after the PFS will be well funded.”
The research project brings together three groups with the unique assets and skills to bring the Lake Hope project to fruition.
Impact has developed innovative metallurgical processes to produce HPA and fertiliser by-products from the salts in the Lake Hope deposit, which will be mined and trucked to Kwinana for processing. The mining and processing will have a minimal environmental footprint, with no on-site beneficiation required at the mine, nominal long-term rehabilitation requirements and one of the lowest Scope 1 and Scope 2 CO2 emissions of any HPA production process globally (ASX Release June 19th 2024).
The Mineral Recovery Research Centre at ECU, led by Associate Professor Amir Razmjou, is a world leader in Membrane Selective Technology (MST) in which plastic or ceramic membranes are used to remove a wide variety of contaminants from reagents and water. The technology is well-established in water treatment, and the MRRC is adapting the technology to the mining industry.
Impact believes MST to be a further game changer for producing HPA, and in particular, for cost-effective reagent regeneration and removal of contaminants in waste water. This, in turn, will lead to lower energy costs, emissions and, in particular, operating costs for the project. It adds to the overall small environmental footprint of the Lake Hope project and the research aims to design a “zero-liquid discharge” project to minimise or even eliminate waste from the process.
CPC Engineering is completing the engineering design studies and estimates of the operating and capital costs for the proposed 10,000 tonnes per annum HPA plant as part of Impact’s Pre-Feasibility Study on Lake Hope (ASX Release October 9th 2024). Eugenia Phegan of CPC, who has previous experience in building HPA pilot plants, recognised the potential of MST for Lake Hope and Impact thanks her for her insight and energy in helping design and complete the grant application as well as her on-going contribution to the Lake Hope journey.
CPC will design, build and manage the pilot plant under the research project. In addition, Impact will also work with ECU and CPC to generate new uses for HPA.
About the Grant and Future Directions
The CRC-P grant of $2.87 million aims to foster the development of competitive, sustainable, and productive Australian industries through strategic research collaborations. Impact Minerals, along with its partners, will fund the remainder of the $6.4 million project, being $3.53 million, with cash and in-kind contributions. Impacts contribution will be about $1.7 million, much of which will be potentially eligibility for the Research and Development rebate of 43%.

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.

Key Projects
Lake Hope HPA Project
Impact Minerals’ Lake Hope HPA project is in Western Australia, a tier-one mining jurisdiction. HPA is a crucial component in many new and emerging technologies, creating ongoing demand for high-grade sources. The Lake Hope project is the company’s flagship as it moves toward production.
Project Highlights:
- Maiden Mineral Resource Estimate: A maiden mineral resource of 3.5 million tonnes at 25.1 percent alumina (Al2O3) for a contained 880,000 tonnes of alumina has been defined at the Lake Hope HPA Project. About 88 percent of the resource, or 775,000 tonnes of alumina, is in the higher confidence indicated resource category.
- Amenable to Open-pit Mining: The Lake Hope project is a unique HPA asset amenable to shallow, open-pit mining. The deposit is soft and shallow, allowing for cheap digging and minimal infrastructure requirements. This type of deposit also lowers the environmental footprint of the operation.
- Fast-tracked to Production: A mining lease application is currently underway. Once granted, the company will begin working towards a pre-feasibility study and mini pilot plant. Impact Minerals plans to reach a complete pilot plant by 2026.
- Impressive Results of the 2023 Scoping Study: Outstanding economics show Lake Hope to potentially be the lowest-cost producer of High Purity Alumina (HPA) globally by up to 50 percent. Key outcomes from the scoping study include:
- Annual production of 10,000 tpa of 4N HPA with an initial 25-year mine life
- Annual EBITDA of A$174 million.
- 2 years construction period with 5,000 tonnes of production during the first year, 8,000 tonnes in the second year and 10,000 tonnes of production thereafter.
- US$934 million post-tax NPV8 at an IRR of 55 percent.
- Mining Lease Application: Amining lease application was lodged in mid-2024 over the West Lake resource while a miscellaneous licence application (L63/99) was lodged to cover mine infrastructure and haulage road.
The scoping study was underpinned by a sulphuric acid process allowing the company to achieve a new milestone by producing HPA with purity of more than than 99.99 percent (4N) from the metallurgical processing of lake clays acquired from Lake Hope. The company further identified a new proprietary metallurgical process for producing HPA from the lake clays. Known as the low-temperature leach (LTL) process, this also produced 99.99 percent (4N) Al2O3 and has the potential to lower even further the capital and operating costs to produce HPA compared to the sulphate process. The LTL process will be included in the ongoing pre-feasibility study along with the sulphate process to determine the best processing route to HPA. The PFS is due to be completed in late 2024.
Broken Hill Copper Project
The Broken Hill project has a significant land position of 815 square kilometers and hosts multiple targets with the potential for high-grade copper. Broken Hill is located in New South Wales, Australia, an area known for its prolific silver-lead-zinc mining operations and the giant Broken Hill deposit.
Project Highlights:
- Participant in the BHP Xplor Program: Impact was selected for the BHP Xplor program in 2023 based on its Broken Hill project. The program is designed to allow participants to accelerate growth and establish a long-term partnership with BHP.
- Potential for Additional Minerals and Deposits: As well as copper, the project has significant exploration potential for magmatic nickel-copper-PGE sulphides, and at the time the host rocks were formed, Broken Hill was located close to the world-class nickel-copper-PGE deposit of Jinchuan and the significant Lengquisheng deposit. The project area also has the potential to contain zinc-lead-silver deposits, providing even more value.
Arkun Nickel-Copper-Gold-Lithium-REE Project
The Arkun project is a 2,900-square-kilometer nickel, copper and gold project located in the emerging Ni-Cu-PGE province near the world-class Julimar Ni-Cu-PGE deposit and surrounded by Anglo American Corporation, which secured its ground holding shortly after Impact secured its asset. Anglo-American is one of the world’s top ten mining companies, and their presence in the region brings confidence in the project’s potential.
Project Highlights:
- Additional Exploration Underway: Impact plans follow-up work programs, including drilling, at its priority targets.
- Significant Targets Identified: Recent soil sampling identified two new prospects:
- Hyperion prospect - Located in the northwestern part of the project area returned with rare earth element anomalism of up to 5,880 ppm (0.59 percent) total rare earth oxide (TREO+Y) and neodymium and praseodymium (Nd+Pr) of up to 21 percent.
- Caligula prospect - Initially identified on the roadside, the Caligula prospect is a large and significant target for porphyry copper mineralisation.
- Three New Exploration Licences: Impact applied for three new exploration licences expanding Arkun project along trend from the recently discovered REE soil geochemistry anomalies at Hyperion, Swordfish and Horseshoe as well as the Caligula copper anomaly.
