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.

Impact Minerals Limited
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 recent 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. Its main uses are 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.
Impact is currently focused on lodging a mining lease application. The company 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 AL203) 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.
In June 2023, Impact announced 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. The company recently announced a key milestone having produced 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 on schedule in late 2024.
A comparison of the LTL process and the sulphate process
The company received a significant research and development refund of $753,000 from its exploration activities completed in the financial year ending June 30th, 2022. 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 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 has become 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: The company is currently awaiting its Mining Lease Application. 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.
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 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.

Kirgella Gift and Providence: First Inferred Mineral Resource Estimate of 76,400 oz Au from only 3m depth
Highlights
- First Inferred Mineral Resource Estimate for Kirgella Gift and Providence of: 2.34 Mt @ 1.0 g/t Au for 76,400 oz at a 0.5 g/t gold cut-off from only 3m depth.
- Gold mineralisation remains open at depth and along strike between Kirgella Gift and Providence:
- Potential for significant resource growth and upgrade following additional drilling to expand on unclassified blocks outside current model limits.
- Highly economic discovery with KalGold’s direct exploration expenditure cost (drilling and assay) of only ~A$4.20 per gold ounce.
- KalGold’s Total Mineral Resource base, comprising this new resource from the Pinjin Project, and the La Mascotte deposit at Bulong Taurus (see ASX: KAL 7th March 2023), now stands at 214,300 oz.
- Elevated gold price of over A$3,600/oz continues to drive interest in mineable gold projects.
KalGold Managing Director and CEO Matt Painter said:
“KalGold is proud to report the first Mineral Resource Estimate at the Kirgella Gift and Providence gold deposits. It totals ~76,000 oz defined at over 1.0 g/t Au from only 3m depth, remains open in several directions, and is considered the first step in defining the full potential of the Kirgella Gift and Providence gold deposits. Pleasingly, we have defined a shallow gold resource at a very low cost to the Company of around A$4.20 per gold ounce.
The Kirgella and Providence mineral resource estimate is comparable to other deposits within the Laverton Tectonic Zone and is considered typical of the region. This is particularly true of some of the constituent deposits at Ramelius Resources’ (ASX:RMS) Rebecca Gold Project, around 20 km to the south along strike.
KalGold now has defined a total resource base of 214,300 oz of gold. The increased resource base enables KalGold to commence high level mining optimisation studies to assess pathways to production. KalGold looks forward to continuing to progress its work in the Pinjin area with the aim of significantly growing this initial JORC Code (2012) resource and defining a suite of additional shallow resources.”
First Gold MRE at KalGold’s Pinjin Project
The Inferred MRE of 2.34 Mt @ 1.0 g/t Au for 76,400 oz Au has been defined at a 0.5 g/t gold cut-off from the Company’s recent drill focus on the shallow portion of the Kirgella Gift and adjacent Providence gold deposits (see Table 1), combined with thoroughly validated historic datasets. Work continues on both deposits, with gold mineralisation open at depth and along strike between the two. This MRE is expected to form the basis of future updates as drilling and exploration continues.

Acquisition of Mubende Gold Project, Uganda
HIGHLIGHTS
- The granted exploration license EL00379 covers 202 square kilometres in the Mubende region west of Kampala and includes the highly prospective Bukuya prospect.
- The Bukuya prospect is currently being mined by 60-80 artisanal workers over 600 metres of prospective strike and remains open along strike and at depth.
- Rock chip samples taken from a recent site visit to the Bukuya prospect by consultant geologists returned numerous specimens containing visible gold in both ferro-manganese and quartz veins.
- Experienced in-country technical team appointed including Mr Dylan le Roux and Mr Allan Agumya to manage exploration activities.
- Field activities scheduled to commence 05 August 2024.
Commenting on the acquisition Managing Director Mr Mathew Walker stated, “We are delighted to have secured a significant land holding that has prospectivity confirmed by a strong presence of artisanal mining activity. Uganda has a well established gold mining industry and regulatory protocols that add to the appeal of the acquisition. We look forward to the commencement of field activities in the immediate term.”
MUBENDE GOLD PROJECT
The Mubende Gold Project is an extensive landholding of 202 square kilometers that covers a series of metasediments, predominantly characterized by meta-wacke’s and phyllitic slates, with occasional interbedded quartzite units and mafic volcanics. Late-stage granites have intruded the metasediments, mainly in the southern part of the license.
Figure 1: Regional Map with locations of Sifang licenses.
At the Bukuya prospect, wall rock consists of metapelitic units with vertical foliation trending NW in most shafts, turning EW in the northern artisanal shafts. Mineralization appears confined to a deformation zone within the metapelites and hosts three subsets of veins exploited by artisanal workers. The first subset includes quartz veins with hematite mineralization, iron-oxide staining, and goethite/limonite-filled vugs, seen in southern shafts with NW trending foliation. The second subset comprises metallic veins of blueish-grey and black ferro-manganese mineralisation with botryoidal textures and specular hematite, found in northern shafts with EW trending foliation. The third set comprises massive milky white quartz veins.
These veins are described in more detail below.
Type 1 (Iron-rich quartz veins): These are quartz veins that show varying degrees of ferro(-manganese) mineralisation. Mineralisation occurs as hematite (red), specular hematite (dark silver/black), and a lesser degree of manganese (botryoidal, blue-grey to black). Vugs filled with limonitic material is often seen in these veins and is interpreted to represent leached out sulphides. These veins are seen in the SE of the Bukuya site. They are typically decimetre to metre scale and are foliation concordant (vertical to subvertical with dominantly NW trend).
