Yuinmery Drilling Yields 1.97% Copper Intercept in June Campaign
Empire Resources has released final assay results from its June 2025 drilling at the Yuinmery Copper-Gold Project, revealing promising high-grade copper intercepts and broad mineralised zones that warrant further exploration.
- 21 reverse circulation holes completed for 2,593m across six prospects
- High-grade copper intercepts up to 1.97% Cu at YT01 prospect
- Broad zones of low to moderate copper-gold mineralisation at YT12, YT19, and Marcus-Augustus
- Follow-up air core drilling planned west of YT01 to test mineralisation extensions
- Project hosts a JORC Inferred Resource of 2.52Mt at 1.31% Cu and 0.49g/t Au
Exploration Update at Yuinmery
Empire Resources Limited (ASX, ERL) has announced the final assay results from its June 2025 reverse circulation (RC) drilling program at the Yuinmery Copper-Gold Project, located approximately 470km northeast of Perth in Western Australia. The campaign comprised 21 holes totaling 2,593 meters, targeting six copper-gold prospects within the Youanmi greenstone belt.
The standout results came from the YT01 prospect, where drilling confirmed a potential westward extension of copper-gold mineralisation. Notably, hole YRC25-10 returned two high-grade intercepts exceeding 1% copper, including a 2-meter interval grading 1.97% Cu and 0.24g/t Au from 85 meters depth. These intercepts suggest the presence of discrete ore shoots with significant sulphide mineralisation, including chalcopyrite and malachite.
Broader Mineralisation Across Multiple Prospects
Beyond YT01, the drilling program intersected broad zones of anomalous copper mineralisation at the YT12, YT19, and Marcus-Augustus prospects. These included intervals such as 43 meters at 1,172ppm Cu at YT12 and 28 meters at 1,301ppm Cu at YT19, indicating a widespread copper system with potential for resource growth. The Magnetic Hill prospect yielded modest copper and gold values, while the Main Road prospect returned no significant results.
The Yuinmery project is notable for hosting the Just Desserts volcanogenic massive sulphide deposit, which currently holds a JORC 2012 Inferred Resource of 2.52 million tonnes grading 1.31% copper and 0.49g/t gold. The recent drilling results add to the geological understanding of the area and highlight new targets for follow-up.
Next Steps and Exploration Outlook
Empire Resources plans to follow up the encouraging YT01 results with additional air core drilling to the immediate west, aiming to delineate the extent of the higher-grade mineralisation. A comprehensive field assessment is also being prepared to review existing prospects and develop new copper and gold mineralisation models across the project area.
With an experienced exploration team and a portfolio of promising targets, Empire is positioning itself to unlock further value from the Yuinmery project. The combination of high-grade shoots and broad mineralised zones presents an intriguing opportunity for resource expansion in a well-established mining region.
Bottom Line?
Empire’s June drilling results at Yuinmery set the stage for targeted follow-up, with high-grade copper shoots offering a tantalising glimpse of potential resource growth.
Questions in the middle?
- Will follow-up air core drilling confirm the lateral extent of high-grade mineralisation at YT01?
- How might these results influence the timing and scale of a potential resource upgrade?
- What new geological models will emerge from the planned field assessment across multiple prospects?
