Highlights
• Drill permit issued: 2,300m RC program to test three (3) highest priority Pipe Targets
• Drilling rig contracted: UDR1000 multi-purpose rig – Resolution Drilling (NSW)
• 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
• Earthworks to commence shortly
• Drilling to commence mid-June as planned
This planned drill program represents a decisive step in testing for concealed porphyry systems beneath shallow cover along the margin of the proven Macquarie Arc, home to world-class Cu-Au porphyry mines. This is exactly the type of generative exploration needed to drive the next generation of copper discoveries critical to meeting the growing demand for gold and copper.
