Pinnacle has completed an auger drilling program that is expected to deliver a resource estimate for the Bills Middle target within its Bobalong kaolin project.

While assays are pending for the 41-hole program, the company’s initial observations have been encouraging enough for it to recommence discussions with potential offtake partners for a direct shipping ore kaolin product from the project in WA’s Great Southern region.

Bobalong is Pinnacle Minerals’ (ASX:PIM) most advanced project with a Scoping Study already underway and preliminary design planning about to begin.

Options to increase value such as calcination to metakaolin and the commercial extraction of the silica component are also being considered.

Kaolin is used in the paper and ceramics industries, although new applications are always being discovered, while metakaolin is a potential cement replacement that can deliver a stronger yet lighter concrete product.

Drilling objectives

The drill program was designed to gain a deeper understanding of the geology at Bills Middle, allowing the company to better predict where the concentration of higher quality kaolin is located within the target area and elsewhere at the Bobablong project.

Initial findings will also be used to start preliminary planning for potential operations with consideration taken for Pinnacle’s high ESG standards and the need to undertake sustainable development in a productive agricultural area.

This includes the potential to develop Bobalong with several smaller, discrete pits rather than a single large pit to minimise the social and environmental impact.
