Slide 47: Why look for porphyries in western Victoria?
STAVELY PROJECT Why look for For personal use only porphyries in western Victoria? And while the ‘ancient’ porphyry deposits can be amongst the largest copper deposits known to man…
Slide 48: Why look for porphyries in western Victoria?
STAVELY PROJECT Why look for For personal use only porphyries in +100Moz western Victoria? …they are indeed the +40Moz ‘elephants’ of gold deposits. To put it in context, it is like having a chance to discover another Kalgoorlie.
Slide 49: Summary: Take Away Messages
SUMMARY Take Away Messages For personal use only 1. Stavely Minerals has conclusively demonstrated that copper plus gold alkalic porphyry-style mineralisation is present at Thursday’s Gossan 2. Results to date are great but we are not yet in the sweet spot and grades should be very attractive when w
