Three large and significant soil geochemistry anomalies for a range of battery metals and precious metals have been identified at Impact Minerals Limited's (ASX:IPT) 100% owned Beau Project, part of the greater Arkun- Beau-Jumbo project area in the emerging mineral province of southwest Western Australia (Figure 1).
Highlights:
- Four large and significant soil geochemistry anomalies identified, including:
- a large copper-nickel-PGM-silver-cobalt anomaly up to 2.5 km by 1 km in size and associated with previously unrecognised layered mafic gabbros
- a gold-palladium anomaly about 500 metres in diameter
- two lithium-caesium-tantalum anomalies each about 1 km in dimension that may be part of a large zoned intrusive pegmatite system
- Field checking and relevant follow-up sampling of all areas will commence by the end of August to identify reconnaissance drill targets as quickly as practicable
- A reconnaissance drill programme will be organised as soon as practicable and subject to access and the harvest period
- There has been no previous exploration at Beau prior to Impact’s work
Impact Minerals’ Managing Director Dr Mike Jones said “These are the first detailed soil geochemistry results we have had from the hitherto poorly explored greater Arkun project area and confirm our belief that the area is very prospective for a range of battery, strategic and precious metals. In addition, it is a validation of our targeting methodology which we have applied across our extensive project portfolio in Western Australia and put together over the past 18 months”.
“A large nickel-copper-PGM anomaly overlies previously unidentified layered mafic intrusive rocks; these are known hosts to significant massive sulphide deposits around the globe. In addition, we have identified a gold anomaly that is associated with rare earth responses and which may be part of a large intrusion-related system. To cap it all off, we also have identified two areas with significant responses for a range of metals associated with a zoned lithium pegmatite system. Follow-up field checking will commence later this month in order to define targets for first-pass drilling as soon as practicable and to identify the bedrock which is mostly obscured by laterite. We also look forward to getting the results from a further 600 soil samples that are still to come from the northern part of the Arkun project”.
Location of Impact's projects in Western Australia
Previous work by Impact across the Arkun and Beau project areas using a proprietary geophysical-geochemical technology owned by Southern Sky Energy Pty Ltd, identified 17 broad areas of interest, principally for Ni-Cu- PGM mineralisation, for follow-up work (ASX Release 10th June 2021).
Reconnaissance soil geochemistry traverses along gazetted roads and tracks over 15 of these targets identified a total of 22 more specific targets for both Ni-Cu-PGM mineralisation and, for the first time in the area, lithium- caesium-tantalum pegmatites and Rare Earth Elements (REE). A number of the original targets returned anomalous soil results for more than one style of mineralisation. Targets for both Ni-Cu-PGM and lithium were identified at Beau.

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.

High-Grade Gold Confirmed at Bronzewing South
- Partial results received from the diamond tail of drill-hole BWSRC081 with the visible gold zone returning 15.5g/t Au over 0.48m from 416.5m. This high- grade zone is reported within a broader intercept of:
- 8.95m at 1.32g/t Au from 414m, including:
- 0.48m at 15.5g/t Au from 416.5m; and
- 0.55m at 3.52g/t Au from 422.4m.
- 8.95m at 1.32g/t Au from 414m, including:
- Follow-up drilling along strike from these intercepts is scheduled to commence in the coming days to define the extent of the south-trending zone of gold mineralisation with a diamond tail of drill-hole BWSRCD086.
- Drill results indicate the inadequacy of historical air-core drill testing with a significant search space now open on the boundary with the historical Bronzewing Mining Lease.
- Diamond drilling at the Central Target, located ~1.7km to the south of the Eastern Target and within the same structural corridor, has encountered zones of intense locally massive quartz veining associated with brecciation below historical Hammer gold drilling anomalies of:
- 20m at 1.5g/t Au from 120m in drill-hole BWSRC0037, including:
- 8m at 2.4g/t Au from 120m; and
- 4m at 3.9g/t Au from 120m.1
- 20m at 1.5g/t Au from 120m in drill-hole BWSRC0037, including:
- Assay results from the remaining program will be progressively released in the coming weeks.

Hammer’s Managing Director, Daniel Thomas, said:
“The confirmation of high-grade gold mineralisation at Bronzewing South is a significant step in our search for an economically viable gold target at our Yandal Gold Project. High-grade mineralisation can be traced with multiple intercepts to the north of our project area, with the mineralised structure interpreted to extend for hundreds of metres.
“We will now look to test this structure approximately 100m further south on our project area. We are very much looking forward to follow-up drilling at the Eastern Target, as we enter a zone without any previous drilling coverage.
“The team is encouraged by the observations in recent drilling at the Central Target and the potential for this corridor to be connected to the Eastern Target drilling some 1.7km to the north. This corridor is largely untested below the ineffectual air-core drilling and, with a prominent shear zone interpreted to connect these targets, it is of high interest to the team in our search for a significant gold discovery.”
