Slide 8: Exploration History
Exploration History For personal use only • EL 4022 was acquired from CRAE (Rio Tinto Exploration) in 2004 with the initial interest being the historically mined (70koz) high grade quartz vein at Bodangora (Mitchell’s Creek mine). • Following drill testing of Bodangora by Alkane (with very few inter

Boda Geology – Intrusive Rocks For personal use only • Intrusions comprise of high-K calc-alkaline to shoshonitic monzodiorite and monzonites. • Monzogabbro and monzodiorite intrusives are feeder dykes and are pre- mineral. • Monzonite dykes host only late-mineral quartz- chalcopyrite veins suggesti
Slide 12: Boda Geology – Intrusive Breccias
Boda Geology – Intrusive Breccias For personal use only • Magmatic-hydrothermal breccias appear to be the focus of the extensive calc- potassic alteration at Boda. • Series of NW trending monzodiorite intrusions form a vertical 300m x 500m stock of intrusive breccias central to Boda. • Intrusive bre
Slide 13: Mineralisation
Mineralisation For personal use only • ~3km of continuous >0.2g/t gold mineralisation from Kaiser to Boda Three prospects. • Approximately 60,000 metres of drilling at Boda for the maiden resource estimation.
Slide 14: Mineralisation
Mineralisation For personal use only • Calc-potassic alteration assemblage of biotite-actinolite-epidote- magnetite. • Higher Au-Cu grades centred around sulphide cemented breccias of calc-potassic altered volcanics. • Veining proximal to the breccias is dominantly calcite-quartz and typically sulph

Slide 22: Summary
Summary For personal use only • Boda is a Au-Cu alkalic porphyry system associated with intrusive-hydrothermal breccias of a host sequence of basaltic -andesites. Boda represents a probable unique style of significant Au-Cu porphyry mineralisation for the Macquarie Arc. • Exploration work continuing
