Highlights
- Altitude completed a 1,501m, five-hole drilling program at the Byrock Project, comprising 1,158m of reverse-circulation (RC) drilling and a 343m diamond-core tail. The program tested three of four priority Pipe Targets for concealed “pencil-style” copper-gold
porphyry systems. Rainfall prevented access to the 4th target, which remains untested. - Assays have been received for the completed RC drilling. No significant copper mineralisation was identified, although minor gold mineralisation was intersected in hole 26BY04, including 27m at 0.06g/t Au from 42m.
- Visual logging of the diamond-core tail in hole 26BY05(T) identified no significant base-metal mineralisation. Multi-element assays and gold fire-assay results are expected in the coming weeks to confirm the visual observations
- Drilling validated the geophysical interpretation of pipe-like bodies and confirmed deep crustal-tapping structures and previously unmapped volcanic rocks, interpreted to form part of the Macquarie Arc. However, the intersected basaltic and ultramafic rocks appear younger and less fractionated than the targeted felsic igneous rocks
- At Target P38, drilling intersected a volcanic breccia pipe containing abundant large clasts of the targeted felsic intrusive rocks. These clasts will undergo further fertility and prospectivity analysis as part of a broader project review following receipt of assays.
- Based on the results received to date, the Byrock Project has not met the Company’s technical criteria for further drilling expenditure. The project will be placed under review pending the outstanding diamond-core assays and fertility analysis, after which the Company will determine its future involvement in the project.

Altitude Minerals Podcast
EP02: Copper Gold Porphyry
In the latest episode of the Altitude Minerals Podcast, Managing Director Duncan Chessell is in conversation with world-leading geochemist and in-house porphyry expert Professor Bruce Schaefer to explore these elusive and valuable mineral systems, which account for roughly three-quarters of the world’s copper and a fifth of its gold.
