Slide 6: What did BCD sell?
What did BCD sell? Two near production copper projects with a Scoping Study completed. Envisaged a crusher / sulphide concentrator at Stavely High-grade copper-gold feed from Mt Ararat VMS blended with low-grade feed from Thursday’s Gossan chalcocite Rail to port through the project area 62Mw wind f
Slide 7: Scoping Study Update
Scoping Study Update Stavely Minerals plan to update the previous Scoping Study: Previous Scoping Study identified an opportunity to beneficiate the mineralisation in the chalcocite enriched blanket by washing out kaolin clays prior to sulphide concentration Drill twin holes at the Thursday’s Gossan

Slide 26: Stavely Project
Stavely Project Stavely Minerals bought these projects primarily for the exploration upside A significant factor was that previous explorers had failed to recognise the high- level of exposure – ie. The porphyry was down deeper than existing drilling Copyright © 2013 www.stavely.com.au All Rights Re

Slide 30: Stavely Project
Stavely Project “The HyLogger data certainly supports the hypothesis that the level of exposure tested by previous drilling is analogous to the top of a Prince Lyell system. This system should be drilled to a depth of 200 to 300 meters below the zones of shortest wavelength white mica recorded from

Slide 32: Level of exposure of Thursday's Gossan
Level of exposure of Thursday’s Gossan “The multi-phase intrusions, multi- generations of quartz veins and strong hydrothermal alteration zonation apparent at the Thursdays Gossan project are indicative of the mineralisation and alteration recognised above many large SW Pacific rim porphyry copper-g
Slide 33: Evidence of untested porphyry Cu-Au mineralisation at depth
“Therefore there is strong evidence indicating that there is untested porphyry Cu- Au style mineralisation at depth below the Thursday Gossan project area.” Corbett and Menzies Consulting 2013 Copyright © 2013 www.stavely.com.au All Rights Reserved

Slide 40: Our View
Our View The primary contention is that previous explorers failed to recognise the high level of exposure of the Thursday’s Gossan porphyry complex and that the potential for well-mineralised copper-gold porphyry(s) at depth is excellent. The Stavely area is compared to the Cadia Valley and Goonumbl

Slide 42: Proposed work programmes for the Stavely Project
Proposed work programmes for the Stavely Project Almost all diamond drilling to date (except 2 holes) is to a maximum true depth of ~250m – not deep enough to discover Cadia Ridgeway or Cadia East At the Thursday’s Gossan area (including Drysdale, Junction 1 and Junction 3), propose drilling: 15 x 7
