Explorer Minotaur has reported a significant upgrade of its kaolin project near Poochera on upper Eyre Peninsula in South Australia.

Kaolin is a mineral derived from granite formations and used in paint, porcelain and medical products.

Minotaur has drilled across 96 hectares of its Careys Well prospect and expects it to produce about eight million tonnes of refined kaolin.
The best-quality product can sell for more than $200 per tonne.
