Andromeda Metals Ltd. has obtained its first national patent for its novel High Purity Alumina (HPA) and Smelter-Grade Alumina (SGA) production process.
The patent, issued by the Republic of South Africa to Andromeda’s wholly owned subsidiary Andromeda Technologies Holdings, represents the initial approval within a broader international Patent Cooperation Treaty application portfolio.
Developed over eight years of research and testing, the proprietary process uses kaolin feedstock sourced from Andromeda’s Great White Project in South Australia.
The technology is designed to establish a low-cost, lower-carbon pathway to manufacture premium HPA, an essential component in lithium-ion battery separators, semiconductors, LEDs, synthetic sapphire, and advanced ceramics.
The regulatory approval follows continuous pilot-scale testing that achieved 4N HPA production with a measured purity of 99.9986 per cent. Additionally, Andromeda recently entered into a agreement with Traxys North America to facilitate the distribution of HPA into the United States market.
A 2025 scoping study outlined a staged development strategy targeting up to 10,000 tonnes per annum. The study highlighted strong project economics, including an estimated pre-tax net present value of AU$1.48 billion and average annual EBITDA of AU$247 million.
Andromeda Acting CEO Sarah Clarke said the patent validates the originality of the company’s process and supports its commercialisation goals.
“The granting of the first national patent is an important milestone in the development of Andromeda’s High Purity Alumina business and validates the originality of our proprietary technology,” Clarke said.
“Protecting our intellectual property is a key component of our commercialisation strategy. This patent strengthens Andromeda’s competitive position as we advance our HPA Project and seek to establish a new, low-cost and low-carbon pathway for producing HPA from kaolin.”
