Drilling program commenced targeting a maiden MRE at highest priority growth prospect, Blackbeard FINNISS EXPLORATION UPSIDE The Exploration Target is supported by historical drilling, trenching & exploration results. The potential quantity & grade of the Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource & it is uncertain if further exploration will result in the estimation of a Mineral Resource.

The potential production upside is indicative only. The pathway is subject to technical and financial studies, regulatory approvals, funding, market conditions and the development of new mining operations. Factors relating to these matters remain uncertain. The pathway represents an aspiration and is not intended to be a production target, forecast, projection or guidance. The statements relating to the potential production upside are aspirational statements only (and not production targets), and the Company does not have reasonable grounds to believe this can be achieved. These statements are of an aspirational nature and are dependent on several factors, including exploration success, ore reserves and mineral resource definition 2.
