High Purity
Alumina (HPA)
High Purity Alumina is a critical battery material and is an essential ingredient for the production of synthetic sapphire and LED lights. There is no substitute in the manufacture of synthetic sapphire.
Vytas’ High Purity Alumina (HPA)
Vytas has successfully produced a 4N High Purity Alumina (HPA) avoiding the need of hydrochloric acid which is often associated with high capital and operating costs.
The Company intends to explore alternative low cost, low resource methods for the production of HPA directly from kaolinite feedstock, which will be mined from our Tambellup Kaolin Project.
It is the Company’s objective to produce HPA with a 99.99% (4N) or 99.999 % (5N) purity, for the rapidly growth synthetic sapphire, LED lights and lithium-ion battery markets.
HPA
HPA is a high purity form of aluminium oxide Al2O3, which is a critical battery material and is an essential ingredient for the production of synthetic sapphire and LED lights. Global demand for HPA is being driven primarily by the rapid uptake of lithium-ion batteries, as the world transitions to renewable energy sources.
HPA Market
The HPA market is currently growing at a CAGR of 20.7 % and is expected to reach $4.8 billion by 2026 (Allied Market Research, 2020) driven primarily by the rapid uptake of sapphire glass and in LiB where it is used as a separator coating.
The market price for HPA is strongly controlled by quality, and in particular the final alumina composition.
Tambellup Project
The Tambellup Project is located approximately 280 km southeast of Perth and 130 km north of Albany, Western Australia. The project has access to the Port of Albany via the Freight Rail Line, operated by Arc Infrastructure, or the Great Southern Highway.
Mineral Resource Estimate
CSA Global were engaged by the Company to undertake a Mineral Resource Estimate for the Tambellup Kaolin Project.
The Mineral Resource Estimate complies with the recommendations in the Australasian Code for Reporting of Mineral Resources and Ore Reserves 2012 (JORC Code). The Mineral Resources Estimate was compiled by Dr Andrew Scogings (MAIG, RPGeo) and Serik Urbisinov (MAIG) who are both employees of CSA Global with over 30 years of individual experience. Both personnel have sufficient experience which is relevant to the type of style of mineralisation and type of deposit under consideration and to activity which they are undertaking to qualify as a Competent Person as defined by the JORC Code.
The Tambellup Project Mineral Resource Estimate (MRE) is outlined in the table below:
MRE for the Tambellup Project
| Tonnes (Mt) | Yield (-45 µm) (%) | ISO Brightness (%) | Al2O3 (%) | SiO2 (%) | Fe2O3 (%) | LOI (%) |
| 12.5 | 53.5 | > 84.8 | 36.64 | 48.42 | 0.37 | 12.19 |
The estimate is in accordance with JORC Code guidelines and is effective as at 26 April 2022.
Exploration Target
An Exploration Target for Tambellup Project (E70/4969) has been established by CSA Global. Please refer to Section 3.6 of the IGR in the Vytas Prospectus for details on the Exploration Target.
The Exploration Target for the Tambellup Project is provided in the table below.
Exploration Target for tenement E70/4969 of the Tambellup Project
| Tonnes (Mt) | ISO Brightness | Al2O3 (%) | SiO2 (%) | Fe2O3 (%) | LOI (%) |
| 54 – 108 | 79 – 87 | 34– 38 | 47 – 51 | 0.1 – 0.8 | 11 – 13 |
The quantity and grade of the Exploration Target specified above is conceptual in nature. There has been insufficient exploration undertaken to date to determine a Mineral Resource and there is no certainty that further exploration work will result in the determination of a Mineral Resource.
