Summary
• Drilling has commenced to test the seven highest-ranked shallow “pipe-like”geophysical features analogous to North Parkes and Cadia Cu-Au porphyry deposits
• The Byrock Project is an untested company interpreted north-west segment of the Macquarie Arc, which is host to profitable Cu-Au porphyry mines to the south
• Drill targets are under a shallow cover of ~80m
• The 1,500m Aircore/RC drill program will take two (2) weeks to complete
• The company intends to announce assay results upon receip
These shallow drill targets are a low-cost, high-impact opportunity for Altitude, where the potential exists to define “pencil” Cu-Au porphyry deposits, which exhibit a pipe-like geometry, within a previously unrecognised and untested segment of the Macquarie Arc.
If this proof-of-concept drill program is successful, it has the potential to become a flagship project for the Company. Altitude also holds a significant 100% ground position adjacent to the Byrock Project with a similar geological setting and prospectivity.
This will be the 2nd drilling program in three months and is in line with Altitude’s pipeline strategy of unlocking shareholder value through testing for high-quality discoveries
