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.

Additional High Priority Antimony Targets Identified over 10km Corridor at Yallalong Project
Highlights
- Ground geophysical survey over the identified 10km antimony corridor at Yallalong is complete and final data has been processed and interpreted.
- Detailed interpretation of the geophysical data integrated with previous drilling data significantly expands the scale of the exploration model for high-grade antimony mineralisation at Yallalong.
- 14 new, high priority, structural targets analogous to the high-grade Discovery Target have been identified and will be evaluated in the next drilling campaign.
The geophysics has identified 14 new structural antimony targets at Yallalong analogous to the Discovery Target, where historic drilling intercepted high-grade antimony.
Octava’s Managing Director Bevan Wakelam stated, "The new gravity data redefines the exploration model for high grade antimony at Yallalong. It explains the presence of anomalous antimony along the structural corridor and predicts potential hot spots along it. It is exciting to consider the possibility of a continuous system extending under cover for more than 10 kilometers and having a method to pinpoint the most prospective zones. Planning work is already underway for drilling of these new targets "
Antimony
The Yallalong project is located ~ 220km to the northeast of the port town of Geraldton in Western Australia. The antimony (Sb) mineralisation identified at Yallalong appears within a 10km north- south striking mineralised corridor.
Previous exploration identified four principal antimony targets where antimony mineralisation was exposed at surface. Only the Discovery Prospect had previous drilling and recorded high-grade antimony intercepts over a strike length of ~300m, including 7m @ 3.27% Sb.
A detailed geophysical survey was undertaken to identify underlying structures, such as shears and faults, which act as conduits to mineralising fluids. It also outlines key lithological boundaries. These factors are important in the formation of antimony deposits worldwide.
Interpretation of the geophysical data and the historic drilling has re-defined the exploration model for high grade antimony at Yallalong. Fourteen new targets analogous to the Discovery Target have been identified and will be evaluated through planned drilling. See Figure 1.
Figure 1. Summary structural interpretation and with existing and newly identified Sb targets at Yallalong.
Atlas Geophysics conducted the gravity survey using a 100m x 100m grid pattern, with additional measurements on a 50m x 50m grid over the Discovery Target. NewGen Geo, a geophysical consultancy, carried out the gravity data processing and interpretation.

Ore Purchase Agreement with Westgold Resources Unlocks Gold Production from Crown Prince
HIGHLIGHTS
- New Murchison Gold (NMG) and Westgold Resources (Westgold) have entered into an Ore Purchase Agreement (OPA) which will underpin production from NMG’s Crown Prince deposit near Meekatharra, Western Australia in 2025.
- Subject to final regulatory permitting, under the OPA, NMG will commence mining from a new open pit operation at Crown Prince with a targeted commencement date of mid-2025.
- Ore will be hauled 33km by road to the Bluebird Gold Processing Plant, part of Westgold’s Murchison Gold Operations at Meekatharra.
- Ore will be sold to Westgold in several parcels (Ore Parcels) totalling 30-50kt per month with each Ore Parcel certified for grade, moisture and recovery from sampling at the Crown Prince site and a recovery factor agreed for each mining bench from test work replicating the Bluebird Mill circuit.
- The OPA has no fixed term although NMG envisages that most of Crown Prince ore is likely to be processed in an “Initial Period” which runs over the first 24 months of the agreement. Thereafter ore tonnages are to be agreed on a rolling three-month basis once production forecasts have been completed by NMG and Westgold has confirmed mill availability.
- Westgold will purchase ore from NMG based on contained gold in each Ore Parcel at the prevailing AUD gold price in the month the Ore Parcel is collected (minus processing costs and a capital recovery charge). Westgold must promptly collect Ore Parcels that are available for collection.
- The OPA is subject to shareholder approval (Listing Rule 10.1 requirement) at a general meeting of NMG shareholders to be held in late January or early February 2025.
- NMG and Westgold have also entered into an ancillary agreement (Licence and Access Water Discharge Deed) which facilitates NMG’s potential dewatering requirements at Crown Prince.
Alex Passmore, NMG’s CEO commented: "We are very pleased to announce the Ore Purchase Agreement with Westgold as it sees both companies working together to support the development of NMG’s Crown Prince deposit in a capitally efficient manner.
We see this Agreement as beneficial to all shareholders with Westgold acquiring additional high grade oxide ore feed to supplement its Meekatharra operations and NMG transitioning to a producer for modest capital.
The Bluebird Processing Plant owned by Westgold is ideal for NMG due to its close proximity and well-matched metallurgical process. We believe the robust frameworks and protocols we have put in place in this Agreement aligns both operational teams to a common goal of maximizing operational efficiency.
We thank the Westgold team for the technical and commercial work that has led to this Agreement and look forward to working collaboratively in making the development of Crown Prince a success”
Crown Prince is located to the north of Meekatharra, around 33km via road to the Bluebird Gold Processing Plant (Bluebird) owned and operated by BBGO. Westgold and NMG have been working collaboratively on the OPA to manage technical risks and to share economic synergies which are available via the partnering of production from the Crown Prince deposit and milling at Bluebird.
Key Terms of the OPA are outlined in the Table below and will be explained fully in a Notice of Meeting to be sent to NMG shareholders in December. The NMG shareholder meeting is likely to be held in late January or early February 2025. As a result of Westgold’s 18.7% ownership of NMG, it is deemed a related party under the ASX Listing Rules and so the OPA includes a condition precedent of NMG obtaining shareholder approval under Listing Rule 10.1.
BDO Corporate Finance Australia Pty Ltd (BDO) has been engaged to provide an opinion and Independent Expert’s Report to accompany the Notice of Meeting to assist shareholders in their considerations of whether or not to approve the OPA moving into operation.
Should the conditions precedent be met (shareholder approval) the OPA will come into effect with NMG expecting mining approvals to be received in early April 2025. Once mining operations commence, and ore stockpiles are built up, it is anticipated that first Ore Parcel sales will occur in September 2025.
The company is working towards an ore reserve estimate to provide further detail on the economics of the project which is to be released shortly.
