Castle Minerals (CDT) has announced the successful production of commercial-grade graphite concentrate.

The product was produced at the company’s Kambale project, with flake concentrate grading at 95.1 per cent achieved through test work using traditional downstream equipment.

Castle perceives this achievement as a boost to its confidence in its ultimate goal: producing high-quality graphite that meets the stringent standards of EV battery manufacturers.

Graphite is commonly referred to as the “forgotten battery metal.” It is compressed into sheets known as foil, which are used in batteries as anodes.

Anodes play a crucial role in facilitating the flow of electricity within a battery. The concentrate is being sent to experts in Germany for further assessment through electrochemical tests.

This news coincides with a busy period for Castle. The company is anticipating assay results from 43 drillholes recently completed, and it is also planning to initiate a scoping study for Kambale in Q4 of this year.

Notably, Kambale, situated in the African nation of Ghana, provides convenient access to US and EU markets through nearby ports located approximately 240 kilometres away via sealed roads.

CDT shares last traded at 1.1 cents.
