Slide 9: Resource growth potential
Resource growth potential • Limited deep drilling to date – average depth <60m • Four key pathways for Resource growth 1. Convert existing Block Model ounces to Resources 2. Bedrock mineralisation beneath Open Pit Resources 3. Supergene mineralisation outside the Paleochannel 4. Untested bedrock tar
Slide 10: Lack of deeper drilling = significant exploration upside
