TG Metals Limited has delivered a maiden Inferred Mineral Resource Estimate of 6.71 million tonnes at 1.18% Li2O for the Burmeister spodumene lithium deposit within its 100%-owned Lake Johnston Project in Western Australia.

The maiden estimate focuses on material suitable for direct shipping ore, allowing for export without extensive on-site processing beyond basic crushing and screening. Metallurgical testwork has confirmed that simple ore sorting methods can lift the product to approximately 1.5% Li2O.

This is an excellent maiden Mineral Resource at our 100%-owned Lake Johnston Lithium Project and provides a strong foundation for the initial development of the Burmeister deposit. The current resource has been defined with a focus on potential DSO material to support early development. At a grade of approximately 1.2% Li2O, before ore sorting, Burmeister is considered to be well within current DSO specifications for comparable deposits in Western Australia.

Alongside the resource estimate, TG Metals defined an additional in-pit Exploration Target ranging from 11 million to 14.5 million tonnes grading between 0.90% and 1.20% Li2O. The company holds an interest in the Van Uden Gold Project elsewhere in Western Australia, but current development efforts remain centered on Lake Johnston.

The company has already submitted a Mining Lease application for the Burmeister deposit. Upcoming workstreams include resource definition drilling targeting the Exploration Target in the third quarter of 2026, alongside core drilling designed to supply direct shipping ore samples to potential offtakers.
