Peak Rare Earths Limited (ASX: PEK) (“Peak” or the “Company”) is pleased to announce the final set of assay results from its critical minerals exploration programme, which is targeting the multi-commodity potential of the Ngualla carbonatite system.
- Critical minerals exploration programme is supporting the multi-commodity potential of the Ngualla carbonatite system
- Completion of all remaining assays from the current drilling:
- 7 RC drill holes from the Northern Zone as well as 11 RC and 2 DD drill holes from the Breccia Zone
- Assays from Breccia Zone confirm outstanding high-grade thick intercepts of fluorspar supporting the potential of a globally significant fluorspar deposit:
- NRC390: 80m at 30.8% CaF2 from surface including 10m at 53.3% CaF2 from 34m
- NRC408: 34m at 44.2% CaF2 from surface including 10m at 59.2% CaF2 from surface
- NDD048: 68m at 30.6% CaF2 from surface including 6m at 61.5% CaF2 from surface and 8m at 58.1% CaF2 from 12m
- Prospectivity of Breccia Zone further enhanced by significant high-grade rare earth mineralisation as well as elevated levels of niobium:
- NRC408: 34m at 3.77% TREO from surface including 8m at 4.87% TREO from 2m and 16m at 4.63% TREO from 14m
- Final assays from Northern Zone extend the area of high-grade phosphate mineralisation, supporting the recently identified opportunity to supply phosphate into local fertiliser sector:
- NRC384: 28m at 16.7% P2O5 from 6m and 41m at 22.9% P2O5 from 39m to end of hole
- NRC388: 40m at 20.3% P2O5 from 6m,
- Ongoing engagement with strategic parties around low-cost phosphate and fluorspar development options that could complement the delivery of the Ngualla Rare Earth Project
- Further drilling to be evaluated as part of the next phase of the exploration programme
Assay results cover a maiden drilling campaign in the Breccia Zone, comprising of 11 Reverse Circulation (“RC”) and 2 Diamond Drill (“DD”) holes. They confirm extensive high-grade and thick intercepts of fluorspar across the Breccia Zone (Figure 1) supporting the potential of a globally significant fluorspar deposit at Ngualla. High-grade rare earth mineralisation and elevated levels of niobium have also been intercepted within the Breccia Zone; further enhancing the prospectivity of the area.
The final set of assays from 7 RC holes within the Northern Zone have also been finalised. These demonstrate further high-grade intersections of phosphate, further extending the existing extent of phosphate mineralisation in the south direction.
Both fluorspar and phosphate are increasingly strategic critical minerals:
- Fluorspar is used in electrolytes within lithium batteries and to purify graphite anodes; and
- Phosphate is used in lithium iron phosphate EV batteries and fertilisers, which are critical to boosting food security and agricultural yields in Tanzania and East Africa.
Commenting on the assay results, Bardin Davis, the CEO of Peak, said:
“The results from our maiden drilling campaign in the Breccia Zone are extremely exciting and confirm a major fluorspar discovery. Fluorspar is an increasingly strategic critical mineral, and we have the potential of a globally significant deposit. The final assay results from the Northern Zone are also very pleasing and further extend the mineralisation area of high-grade phosphate.
We intend to further assess the potential for low-cost development options for these two commodities”.
Results overview
The assay results from 18 RC holes and 2 diamond holes across the Northern Zone and Breccia Zone covering a total of 1,533m are included within this latest batch of results (Figure 2). Drilling in the Breccia Zone has targeted the southern and northern extent of the area where previous trench samples identified high-grade fluorspar at surface. The final set of drill holes from the Northern Zone has focused on infill between the current mineralised area and the Bastnaesite Rare Earth Zone, which lies ~1km south of the Northern Zone.
All assays pertaining to the current drilling campaign have been completed and covered a total of 57 drill holes for a total of 4,200m (Table 1).

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.
