Section A – A’ planned RC drill holes (26PL03 – 05) through the P38 Target, Byrock Project – drill tested with shallow aircore holes (ASX 6/2/2026) in November 2025 – prospective for a porphyry system. 3D inverted magnetic susceptibility shell 3000 x 10-5 SI (red) (ASX 7/5/2025) and 0.05 g/cc inverted density [gravity] shell (blue)
Highlights
- Compelling RC drill targets have been confirmed at the Byrock Project to test for
Macquarie Arc pencil (pipe-like) porphyry deposits - Processing of newly acquired gravity and passive seismic data has been completed, and
integrated with 2025 magnetics data and alteration studies to predict depth to target and
optimise RC drill collar locations - The Byrock Project is a Company interpreted north-west segment of the Macquarie Arc, which hosts the economic Cu-Au porphyry Cadia and North Parkes mines to the south. These deposits exhibit “pipe-like” geophysical features with dimensions analogous to targets within the Byrock Project
- Drill permits submitted and expected in late May 2026, with RC drill rig availability confirmed for planned drilling in June 2026
I am pleased to confirm final RC drill collar locations for our three highest-priority Cu-Au porphyry targets at Byrock in the Macquarie Arc, NSW. These targets reflect disciplined screening of multiple prospects using geophysics, air-core drilling and alteration studies, narrowing our focus to the most compelling opportunities along an interpreted extension of the Macquarie Arc. This drilling represents a decisive step in testing for concealed porphyry systems under shallow cover; exactly the type of generative exploration that drives new discoveries on the margins of proven world-class mineralised belts.
