The list of potential markets for Andromeda Metals’ (ASX:ADN) ‘Great White’ halloysite kaolin just got bigger.

Andromeda aims to get the Great White kaolin project in South Australia – already among the world’s largest by reserves and resources — into production in early 2022.

It’s expected to be a long life, low cost, very high return project.

Concrete now joins paints, plastics, lithium-ion batteries, nanotube tech and cancer therapeutics (just to name a few) as “a new and very significant domestic and global market opportunity” for halloysite-kaolin, Andromeda says.

Worth more than $US439.2 billion globally ($603 billion) in 2018, concrete and cement is a huge and rapidly growing market.

The amount of halloysite-kaolin required to strengthen concrete — 1–2kg per square metre — is low enough to be commercially attractive to buyers.

This cement block has not been strengthened with halloysite-kaolin. Probably.

“Once the reduced amount of required processing is factored in, the opportunity becomes extremely compelling,” Andromeda says.

Concrete application areas under testing which are currently all showing positive results include self-consolidating concrete, shotcrete, pool mix and deep foundation pilings.

A large-scale underground shotcrete trial is planned to obtain real-life performance data on the benefits from adding halloysite-kaolin, the company says.

Official Australian Concrete Standards Certification is anticipated in late November 2020.

Andromeda is the kind of story small cap investors love. Its market cap has ballooned from ~$5m to $365m in just under two years.

That’s a 7200 per cent gain.
