Overview
Copper Ridge is a copper-gold prospect in the northern part of the Yambat Project, around 7 km north of the Oval discovery. Identified during 2024 regional reconnaissance, it represents a distinctly different style of mineralisation from Oval and is interpreted as a potential iron-oxide-copper-gold (IOCG)-style system. That makes Copper Ridge an important part of the Company's broader regional pipeline around Yambat.
Geology and mineralisation
The prospect sits adjacent to a regional northwest-southeast fault zone and comprises silicified, magnetite-altered andesitic volcanic and metasedimentary rocks intruded by trachy-rhyolite and granosyenite dykes. Two alteration zones have been mapped, both carrying a chalcopyrite-magnetite-pyrite-malachite assemblage. A 30m-wide by 400m-long mineralised zone has been delineated at surface before dipping under alluvial cover to the east, leaving an interpreted eastern extension untested.
Notable drill intercepts
The following table summarises notable drill intercepts. Please note that full details for all reported intercepts are available in the Appendices A through F of the "Annual Report and Financial Statements 2025" announced on 27 March 2026.
| Drillhole | Intercept | Announcement | Reference |
|---|---|---|---|
| Rock-chip | Up to 0.4% Cu and 0.195 g/t Au from surface sampling | 6 Aug 2024 — Regional Exploration Identifies New Copper & Nickel Targets | View ↗ |
| CRS01A | Continuous disseminated and vein-hosted chalcopyrite from surface over a 200.5 m hole, terminating in mineralisation within a fault zone | 23 Sep 2024 — Drilling Confirms Copper Mineralisation at Copper Ridge | View ↗ |
Exploration to date
Surface rock-chip sampling returned encouraging copper and gold values, and scout drilling has confirmed mineralisation at depth. Five scout holes have been completed at Copper Ridge to date, with early drilling suggesting the system may continue beyond the current test area. The prospect remains early stage, but it is a credible follow-up target within the wider Yambat district.
