Highlights
- Positive air-core drill results identified 3 of 7 Pipe Targets that warrant follow-up validation and likely RC drilling to test for Macquarie Arc pencil (pipe-like) porphyry deposits
- 775 infill gravity stations and 92-line km of passive seismic have been acquired in total over the Pipes Targets and T55 Target in the last month as a validation step
- The passive seismic data will be integrated with new gravity data & 2025 magnetics data to more accurately predict depth to target and optimise RC drill collar locations
- Detailed alteration and petrology studies are approaching completion and will inform final target ranking and optimise drill collar locations ahead of definitive RC drill testing
- The Byrock Project is a Company interpreted north-west segment of the Macquarie Arc, which hosts the profitable Cu-Au porphyry mines of Cadia and North Parkes to the south. These deposits exhibit “pipe-like” geophysical features analogous to the Pipe & T55 Targets on the Byrock Project
- Processing of newly acquired gravity and passive seismic data is underway and will be reported in combination.
Altitude Minerals will shortly identify final RC drill collars and a program of works for our highest priority large-scale potential Cu-Au porphyry targets validated over a 15-month program of methodical appraisal using tectonics, geochemistry, mineralogy, ground and airborne geophysics, air-core drilling, alteration studies and application of the latest porphyry targeting expertise.
I am very much looking forward to being out on the rig when we drill test these Pipe Targets. These targets are exactly what a modern explorer should be doing, testing the boundaries of known mineralised belts for the next generation of deposits under shallow cover, unlocking new exploration spaces and shareholder value.
