Endeavor Mine has the potential to be a long-life +20-year asset in one of Australia’s most prolific mining districts.
Polymetals controls 100% of the Northern Basin, 70km strike.
- Large exploration landholding of 1,107km2
- Four high priority targets to be tested by drilling:
- 4 Tank – gold & copper
- Boundary Tank – gold & copper target
- Furney’s Tank – lead, zinc & gold target
- Kiri – copper & zinc target
- Excellent opportunity to discover and mine ore bodies for processing through our Endeavor mill
- Particular focus on shallow high-grade supergene-style mineralisation.
Our priority is to expand our existing JORC Resources and Reserves.

Major polymetallic (base and precious metals) ore bodies with short strike length and deep depth persistence cluster throughout the basin.
Priority Carpark prospect neighbours existing mine.
- Priority near-mine target immediately south of Endeavor, with potential to extend the known orebody.
- Drilling has intersected broad lead-zinc anomalism, supporting a larger mineralised system at Carpark.
- Untested geophysical anomalies lie under 300 metres from Endeavor, highlighting compelling exploration upside.
Significant potential for the discovery of Cobar style copper deposits.
- Recent regional exploration spans 1,100km² in the North Cobar Basin, building a pipeline of drill-ready targets.
- Geophysics-led targeting integrates geology, geochemistry and historic data to prioritise prospective mineralised systems.
- A 65 line-kilometre IP program will rank seven priority prospects and define drill locations.
