Lefroy Exploration Ltd has returned high-grade gold assays from a 5,046-metre reverse circulation drilling program at the Mt Martin gold deposit in Western Australia.

The strongest results from the program include 8 metres at 3.93 g/t gold from 141 metres, including 3 metres at 9.44 g/t gold in hole LEFR1161, and 6 metres at 5.48 g/t gold from 69 metres, including 2 metres at 12.8 g/t gold in hole LEFR1148.

Several of these intercepts, including the high-grade result from LEFR1161, occur outside the current 460,000-ounce mineral resource estimate. Drilling along the East Shear successfully confirmed grade continuity down-plunge across a 1-kilometre strike length, identifying multiple open, untested high-grade shoots.

“These significant assay results from Mt Martin demonstrate the resource growth potential at Mt Martin. When drilling commenced in April, our primary goal was to unlock shallow, high-grade resource growth potential along strike and down plunge. These assay results highlight that the system holds substantial along strike and down plunge upside.”

“Importantly, these results provide us with a new platform for understanding the best corridors for resource growth. They complement our broader strategy of expanding our 1million-ounce gold resource base. In parallel with the Mt Martin Scoping Study, we are moving quickly to translate this exploration success into improved project economics.”

— Graeme Gribbin, Managing Director

Lefroy is incorporating these results into the Mt Martin Scoping Study, which is on track for delivery during the September 2026 quarter. Concurrently, the team is completing resource modelling to update the high-grade gold domain within the Burns mineral resource estimate.
