Key Business Segments
High Purity Alumina Processing Technology - HiPurA®
ChemX Materials is developing an innovative processing technology to produce high-purity alumina (HPA). This process is called HiPurA®. ChemX Materials owns 100 percent and holds an Australian patent for HiPurA®. ChemX Materials has proven HiPurA® can produce above 4N (99.99 percent) pure HPA at micro plant scale. This test work has also demonstrated that HiPurA® is superior compared to alternative technologies, offering several advantages, including:
- Lower costs – both capital and operating.
- Independent feedstock - – process is not tied to mine production and uses a readily available aluminous industrial chemical.
- Easily scalable – production output can increase based on demand.
- Modular – can be built near end users’ manufacturing operations.
- Optionality – patented technology can be licenced to end users.
- Lower carbon footprint – technology is not energy intensive.
HPA has several applications, the most important being lithium-ion batteries used in electric vehicles (EVs) and energy storage applications. HPA is used in the coating of the battery separator to enhance safety and performance. The outlook for EVs is very promising. With the adoption of EVs growing rapidly year on year as governments across the globe deploy domestic incentives and regulations to reduce the use of internal combustion engines to meet net zero targets.
HPA is also a key in the production of synthetic sapphire, which is used in LEDs, semiconductors, lasers, optical lenses and medical devices.
ChemX Materials has proven its HiPurA® technology can achieve above 99.99 percent (4N) HPA purity at micro plant scale. Following the technical success of the micro plant, ChemX Materials is constructing a 24 tpa pilot plant in Western Australia. The pilot plant is expected to be operational in June 2024.
In January 2024, ChemX Materials was granted an Australian Patent for its innovative HiPurA® technology. Based on the success of the Australian patent, it is anticipated that ChemX Materials will be afforded similar protections in other international jurisdictions. The patent is important as it provides intellectual property protection as ChemX Materials seeks to commercialise the technology globally.
HPA production from the pilot plant will be used for customer qualification and marketing purposes. ChemX Materials is actively pursuing commercial opportunities globally. Commercialisation options include:
- Build, own, operate a commercial scale plant to sell high purity alumina to end users.
- Licence the HiPurA® technology for deployment at end users’ manufacturing locations.
High Purity Manganese Project
ChemX Materials is developing a high purity manganese project. The Jamieson Tank project is located on two exploration tenements, EL 5920 and EL 6634 in the Eyre Peninsula in South Australia. These tenements collectively cover an area of 718 km2.
ChemX Materials completed a 94-hole drill program at the Jamieson Tank project, totaling 6,164 metres and released its maiden Mineral Resource Estimate in September 2023. The Mineral Resource Estimate reported 13.1 Mt at 5.7 percent manganese, with 21 percent classified as Indicated and 79 percent classified as Inferred.
High purity manganese has essential applications in lithium-ion batteries as a cathode material. Manganese provides energy density, stability and lower costs and is a critical material for modern battery chemistries. As the world pursues decarbonisation it is forecasted that the demand for manganese will grow.
With the objective of the United States Inflation Reduction Act (IRA) to reduce its reliance on Chinese sources of critical minerals, by 2025, the Jamieson Tank project is an important prospect. China currently supplies around 95 percent of the global manganese sulphate.
The South Australian jurisdiction offers excellent infrastructure. The Jamieson Tank project is in a province that is characterised by rapidly growing renewable energy infrastructure (wind, solar and hydrogen) and access to a local skilled workforce. The Jamieson Tank project is accessible by road, approximately 160 kms from the port of Whyalla and near a major regional airport.
The tenements in which the Jamieson Tank project is located also host kaolin and rare earth elements (REE) deposits. The area has historically been well known and explored for its potential for kaolin. The Kelly Tank exploration target is estimated to be 55 - 130 Mt of extractable kaolin.
In 2022, ChemX Materials undertook a drilling program and identified REE hosted within the kaolin throughout the tenements. The drilling program intersected high-grade REE mineralisation with intervals of up to 5 metres @2,468 parts per million total rare earth oxides from 7 metres. Importantly, it remains open in various directions, providing potential exploration upside for future drill programs.

Key Projects
Copper
Tennant Creek
The Tennant Creek project is located in the highly prospective Gecko-Goanna copper-gold corridor of the Northern Territory. A mature project comprising three high-grade copper and gold mineral resources, it contains a combined JORC 2012 mineral resource of 7.3 at 1.7 percent copper and 0.6 g/t gold for 127 kt copper and 145 koz gold. Highly-prospective for further resource growth from resource extensions and new discoveries, Tennant Creek is also located in close proximity to grid power, a gas pipeline, the Stuart highway and the rail line to Darwin.
The area where Tennant Creek is hosted is a re-emerging mineral field with recent neighbouring exploration success from companies such as Emmerson Resources (ASX:ERM) and Tennant Minerals (ASX:TMS). Near-mine targets include the potential to extend resources and open enrichment within the Orlando and Gecko structural corridors.
The current focus for Tennant Creek is to identify and drill high-potential exploration targets with a view to growing the resource base while considering a staged cutback of the existing Orlando open pit to gain access to an ore supply for a fast start option.
Bryah Basin JV projects
Through wholly owned subsidiary Jackson Minerals, CuFe has a 20 percent interest in roughly 804 square kilometres of highly-prospective tenements proximal to the former Sandfire Resources' (ASX:SFR) Doolgunna project and Degrussa copper gold mine, as well as several other prominent gold and copper prospects. Collectively known as the Bryah Basin JV projects, the tenements are currently subject to joint ventures and farm-ins with several companies. The most prominent of these is the Morck Well project, which is under an exploration licence with Auris Minerals (ASX:AUR) alongside the Forrest project.
The Morck Well project tenements cover an area of 600 square kilometres in the highly-prospective region, which has been recognized to have high iron ore potential.
Lithium
North Dam
The North Dam project is a highly prospective lithium tenure situated in the emerging Yilgarn Lithium Belt. Located roughly 50 kilometres south-southeast of the township of Coolgardie, the project is contained within the same lithium belt that contains known spodumene deposits such as Mt Marion, Pioneer Dome, Bald Hill, Manna and Buldania. There have also been several well-known junior exploration successes immediately adjacent to the tenement, including Kali Metals (ASX:KM1), Marquee Resources (ASX:MQR) and Maximum Resources.
To date, work on the project has included defining prospective pegmatites through rock chip sampling, soil sampling and geological mapping. Anomalous lithium and key pathfinder elements have also defined a prospective corridor of roughly 3.5 kilometres in strike length. Columbite and tantalite rock chips selected from a stream bed also contain up to 44 percent niobium and 14.53 percent tantalum.
CuFe has also completed a recent heritage survey and, pending results and conditions, plans to commence a maiden drill program.
Tambourah
The 100 percent owned Tambourah Tenure is a prospective lithium tenure with known gold occurrences. Located roughly 90 kilometres south of the Pilgangoora and Wodgina lithium complexes, and 175 kilometres south of Port Hedland, the project was historically explored for gold and contains known gold occurrences within alluvial material and reef systems. Current work on the project to date has involved geological mapping and rock chip sampling.
Niobium
West Arunta
The fully owned West Arunta consists of three tenements located in the highly-prospective region of the same name. The tenure is known to be prospective for carbonatite-hosted niobium and rare earth element mineralization. Spanning roughly 220 square kilometres, it surrounds Lycaon Resources' (ASX:LYN) Stansmore project and is located 70 kilometres north of several prominent recent discoveries.
CuFe has not yet finalised native title arrangements to commence work in the ground so in the meantime it engaged Southern Geoscience Consulting to undertake a geophysical review of publicly available airborne magnetic data for the tenements including re-processing of said data and 3D unconstrained inversion modeling. Analysis of the total magnetic imagery revealed three anomalous areas across the package, resulting in nine target anomalies for further investigation and exploration.
Iron
JWD iron ore mine
The JWD iron ore operation is an optimised and flexible high-grade, low impurity iron ore operation over the Wiluna West JWD deposit. CuFe has 100 percent interest in the iron ore mining rights agreement for the project, which was started for less than $5 million and produces a high-grade, low-impurity lump iron ore for direct shipping.
At its current production rate, the mine has capacity for 60 kt of lump and 15 kt of fines per month. Mining and crushing is conducted by contractors, with the finished product trucked 800 kilometres to the Geraldton port for export in vessels of circa 6Ma0 kt. The mine also benefits from flexible operating contracts and price hedging, allowing CuFe to more readily react to iron ore price volatility.
Although no JORC reserve has been reported, a JORC resource dated June 30, 2023 reveals an estimate of 9.6 Mt at 63.7 percent iron using a 55 percent iron cut-off.
Yarram
The Yarram iron ore project is a mature development opportunity with the potential for low-cost production. CuFe currently holds a 50 percent interest in the project, which includes operatorship. Partially located on an existing mining lease on freehold land, Yarram has a high-grade DSO resource of 5.6 MT at +60 percent iron as well as a low-grade component of 7.1 Mt with the potential for beneficiation.
Situated 110 kilometres from Darwin Port and adjacent to underutilised mining infrastructure, Yarram also features favourable ore body geometry, with existing infrastructure and services contributing to its low capex and opex.
An initial diamond drilling program provided HG core from two deposits within the project. Physical and thermal metallurgical testing confirms the generation of a lump product with roughly 41 percent yield, elevated gangue levels in the very fine fractions and acceptable thermal and materials handling properties, making it suitable as a blast furnace lump burden feed.
CuFe has also undertaken geotechnical testwork on the diamond drill core to provide parameters for pit optimizations and designs. Final pit shells and a high-level mine schedule have been developed for use in regulatory approvals.
Gold Royalty
Crossroad gold project
Through fully owned subsidiary Jackson Minerals, CuFe holds a 2 percent net smelter royalty over M24/462, which contains Northern Star's (ASX:NST) Crossroads gold project. This project is the subject of a recently approved mining proposal envisaging the mining of 2.67 Mt of gold-bearing ore. The project is expected to commence sometime in 2024 and run for a 36-month period, with the majority of ore mined in the second and third years after pre-stripping.
This project represents a potential near-term revenue source for CuFe with no associated costs.

- Shallow surface and subsurface sampling confirmed surface saprolite clay systems w
- across all Poços tenements, with potential deeper mineralisation upside.
- The project is located nearby to townships, well-developed highways, infrastructure, water access, hydroelectric power and well connected to a commercial port.
ANNOUNCEMENT
Enova Mining Ltd (ASX: ENV) (“Enova” or the “Company”) is pleased to announce assay results from non-invasive shallow surface and subsurface auger sampling at Poços tenements 832.174/2023, 832.175/2023, 832.177/2023, 832.179/2023 and 830.652/2020. The locations of the auger sampling and significant assay intercepts are provided in Figure 2. In accordance with ASX reporting of mineral results, details of the sampling, assay results and other technical details are contained in JORC Table 1 and Significant Results and Auger Sampling Data for Poços Project in Table 2 in Appendix A.
The Poços alkaline complex massif region (Poços) hosts world-class rare earth element (REE) mineral discoveries. Enova aims to replicate the success of peers in the region. Refer to Figure 1 (below) for a location plan of Enova’s tenements and surrounding tenements of IAC REE significance.
Figure 1: Regional location of Poços tenements
Enova is assessing results from the current exploration program and the potential for future air-core drilling program. Regarding tenements overlain by the Pedra Branca APA area and buffer zone, identified during Due Diligence, further clarification is being sought regarding requirements for more impactful exploration in the future, such as air-core/reverse circulation drilling and future development.
Mr. Eric Vesel Managing Director of Enova, commented:
“The assay results from the Poços sampling programme confirm the prospectivity of the tenements, which is not surprising for tenements within the alkaline complex. The largest tenement, located near the southern rim of the complex, was encouraging but with mixed results (Above and below 1000ppm TREO). Overall, the Poços results have returned exceptional near- surface grades which has significant unexplored deeper saprolite strata worthy of follow up exploration. This Phase 1 exploration work was part of our initial reconnaissance to investigate our portfolio of prospective REE tenements.
Our team is currently focused on the CODA maiden drill programme; we recognise the importance of assessing all our other projects. We have arranged a consulting exploration team to explore our Juquiá tenements, a potential carbonatite prospect. There is also REE potential within our Santo Antonio (do Jacinto) tenements based on a strong thorium anomaly3, as shared by SI6’s Pimenta Project.
Enova is now in the envious position of holding two major potential IAC REE project areas: POÇOS and CODA with further areas currently under investigation. It’s remarkable that in such a short period of time, Enova has acquired and brought from concept to exploration stage, two major projects with significant upside and worthy of development.”

47.1% Niobium and 9.01% Tantalum Identified in Columbite Rock Chip at North Dam
HIGHLIGHTS
- Columbite Rock chip sample ND11 sourced from pegmatite returned significant results for Niobium 47.1 % (Nb) and Tantalum 9.01% (Ta) within the North Dam Project.
- This follows up from previously announced (22 August 2023) rock chips collected from a stream bed which returned results 43.93% Nb and 14.53% Ta.
- Anomalous Nb in soil geochemistry is coincident with out cropping pegmatites within the central area of E15/1495, which will be drill tested in the upcoming RC drill program.
- Preliminary heritage survey report now received and supports performing the planned activities, final report is expected this month, with drilling continuing to be targeted to commence in July.
- Infill soil sampling has been completed in targeted zones and results will be incorporated into the final drill hole plans as results are received.
CuFe Executive Director, Mark Hancock, commented“The recent work by the team at North Dam further illustrates the potential of the tenement and although the results are from a columbite chip it shows the potential of the pegmatites across the tenement to host critical minerals other than lithium. We are eager to start our maiden drilling program to further understand the potential of the region”.
As per ASX announcement dated 28th May 2024 a soil geochemistry review, detailed pegmatite mapping and rock chip sampling was undertaken to identify the source pegmatites that have likely shed the columbite and tantalite rock chips along a 97m narrow stream bed which returned 43.93% Nb and 14.53% Ta from sample S254 (refer to ASX release dated 22nd August 2023). A recent rock chip sample ND11 of columbite was collected directly from an outcropping pegmatite located nearby the Niobium soil anomaly and 100m South East from S254.
The selective sample of columbite from weathered pegmatite is biased and does not represent the true concentration of the overall pegmatite but yielded a Niobium content of 47.1% and Tantalum 9.01% (see Figure 1 and Table 1).
Broader zones of anomalous Niobium (>15ppm and > 20ppm) from soil geochemistry have been interpreted (See Figure 2) and are coincident with outcropping pegmatites. These pegmatites to the West will both be mapped in detail for the presence of columbite and have drill holes planned to intersect them as part of the wider RC program, which is primarily targeting Li2O.
A preliminary report has been received for the recent heritage survey and supports performing the planned activities, with the final report expected this month. Following this, preparatory works can be executed prior to mobilisation of the drilling contractor, with drilling targeted to commence in July.
Infill soil sampling work to assist in definition of the priority drill holes has now been completed and results will be incorporated into the drill plans once received.
