Organic Growth Potential

Near-mine exploration activities are on-going with resource/reserve drilling update recently released. Extensive in-fill and deep-hole drilling with more than 43,400 metres of reverse circulation and diamond drilling have been completed.
Efforts have been concentrated on drilling on a closer pattern and testing extensional mineralised targets.
Grass-root regional exploration is also under way with specific attention to gravimetric anomalies identified in the Company’s exploration licences.
