Lefroy Exploration (ASX: LEX) has returned high-grade gold intersections from Mt Martin that extend beyond the deposit’s current 460,000-ounce mineral resource estimate (MRE) and strengthen the case for further resource growth. Drilling also confirmed continuity along the East Shear, where high-grade mineralisation remains open down plunge across an under-drilled strike length of more than 1 kilometre. The results will feed into geological modelling and future targeting while Lefroy progresses the Mt Martin scoping study for completion during the September quarter. Lefroy identified the East Shear as a major growth opportunity because historical drilling and mining were concentrated more heavily on the North Shaft, West, and Main Shear zones. “Importantly, they provide us with a new platform for understanding the best corridors for resource growth [and] complement our broader strategy of expanding our 1Moz gold resource base,” he said.
