Slide 26: Why look for porphyries in western Victoria?
STAVELY PROJECT Why look for porphyries in western Victoria? For personal use only • Porphyries are the major deposit type for global copper production • Porphyries are large metal systems with a well understood alteration zonation typically an order of magnitude larger than the deposit itself – ie.
Slide 27: Stavely Project resource and prospects
STAVELY PROJECT For personal use only • Thursday’s Gossan chalcocite enriched blanket – Inferred Mineral Resource of 28Mt at 0.4% copper containing 107kt copper • Thursday’s Gossan porphyry • Junction porphyry • Newly interpreted Mt Stavely porphyry • Fairview Gold prospect • Wickliffe VMS prospect
Slide 28: Mt Stavely Volcanic Complex and Mt Read Volcanics
STAVELY PROJECT For personal use only • Mt Stavely Volcanic Complex considered the northern extension of the Mt Read Volcanics in Tasmania – demonstrated by Tony Crawford. • MRV hosts the Mount Lyell, Rosebery, and Henty copper-gold deposits. • In the Thursday’s Gossan area a very major intersection

STAVELY PROJECT For personal use only Thursday’s Gossan chalcocite blanket (red) and location of porphyry intrusion at depth (blue) controlled by long-lived structures – regional structural controls expressed at local scale.
Slide 30: Exploration premise for the projects
STAVELY PROJECT • Stavely bought these projects primarily For personal use only for the exploration upside. • Stavely’s premise was that previous explorers had failed to recognise the high-level of exposure – ie. The porphyry was down deeper than existing drilling.
Slide 31: Significant drill intercepts into leakage structures
STAVELY PROJECT For personal use only Significant drill intercepts into ‘leakage’ structures: • ‘D’ veins in the porphyry terminology of Gustafson and Hunt, 1975 • 7.7 metres at 4.14% copper, 1.08 g/t gold and 77g/t silver • 9.5 metres at 2.93% copper, 0.44g/t gold and 42 g/t silver

Slide 35: Drill hole SMD004 at Thursday's Gossan
STAVELY PROJECT For personal use only Drill hole SMD004 at Thursday’s Gossan was providing an excellent ‘vector’ towards the porphyry core at depth to the south but this would be disrupted by the low-angle structure at ~420m depth We were very close, now to use every piece of evidence we can get
Slide 36: Low-angle structure intercepted at ~400m
STAVELY PROJECT For personal use only Drilling intercepted low- angle structure at ~400m depth Alteration and sulphides were indicating close proximity to target potassic core Challenge can be overcome with good geology – we have the tools we need see ASX announcements dated 28 August 2014 and
Slide 37: Results to date
STAVELY PROJECT Results to date For personal use only Thursday’s Gossan Very positive results from drilling the IP chargeability anomaly – increasingly intense alteration, very ‘busy’ drill core, low-grade copper mineralisation in peripheral alteration Intercepted a low-angle structure at ~400-4
Slide 38: First to recognise major low-angle structure
STAVELY PROJECT Stavely has become the first company to recognise the influence of a major For personal use only low-angle structure at Thursday’s Gossan. We believe the target zone to have been offset into an untested position to the north / east. see ASX announcements dated 27 January 2015 and ava
Slide 39: Stavely has compelling exploration potential
STAVELY PROJECT Stavely has compelling exploration potential For personal use only Confirmed porphyry targets with: Well-developed low-grade copper mineralisation in peripheral phyllic and propylitic alteration IP chargeability anomalies correlate well with phyllic alteration Alteration minera
Slide 40: Main take-away messages
STAVELY PROJECT For personal use only Main ‘take-away’ messages: Thursday’s Gossan demonstrates the attributes of an alkalic porphyry copper-gold system We are the first to recognise the impact of a major low- angle structure We believe the ‘core’ of the porphyry – which we expect to be much b
