AGC Hits 102g/t AgEq 540m Below Surface at Achilles, Doubling Resource Depth
Australian Gold and Copper's deepest-ever hole at the Achilles discovery has returned 26m at 102g/t AgEq from 433m depth, extending high-grade mineralisation 540 metres below surface and 250 metres beneath the existing 38.5Moz AgEq resource.
Key Takeaways
- Hole A3DD014 — the deepest ever drilled at Achilles — returned 26m at 102g/t AgEq from 433m, including a 2m interval grading 770g/t AgEq, confirming the system delivers its strongest grades at its greatest depth.
- Mineralisation is now confirmed 540m down dip from surface, more than double the depth of the existing 38.5Moz AgEq Mineral Resource Estimate, which currently extends only to 250m down dip.
- Twenty-three drill holes completed after the December 2025 MRE cutoff were excluded due to assay timing, providing built-in resource growth potential ahead of the next formal estimate update.
- AGC is pivoting near-term drilling focus to shallow oxide RC drilling at Achilles, following a previous result of 42m at 266g/t AgEq from 26m — a lower-cost programme targeting faster resource expansion.
- The company held A$7.1 million cash with nil debt as at 31 March 2026, funding a multi-project strategy across a 2,600km² South Cobar landholding that also includes active drilling at Browns Reef–Evergreen.
