Multiple share price catalysts • Actively drilling with three more upcoming drill campaigns in the next 6 months 2. Undervalued compared to peer comparisons • Sub $20M market cap. presents significant growth opportunities 3. Focused on gold and copper • Strong macro market thematics 4. Projects backed by Tier 1 Partners • Partnered with serially successful people and companies who have a track record of making and monetising discoveries, and successful mining operations 5. Clear strategy to deliver shareholder value • 100% ownership of projects give shareholders direct upside to discoveries & partnerships minimise dilution and financing risk 6.
