Konrad Forrest

4 September 2025 | Perth, WA – Ora Banda Mining (ASX:OBM) has posted a string of standout assays from the first 9 holes of a planned 45-hole (~15,300m) campaign at Waihi, 3km west of its Davyhurst plant, including the discovery of a new high-grade lode and significant depth extensions on the Waihi West Lode. The results strengthen Waihi’s credentials as OBM’s third underground mine, alongside Riverina and Sand King.

The Golden Pole area—historically 81kt @ 29g/t for ~77koz—remains under-tested at depth and shares the same structural setting as the main Waihi system, presenting immediate follow-up targets on the newly identified lode. OBM has 36 holes still to drill in the current program, aimed at growing high-grade shoots and testing additional prospects around the Waihi complex.

MD Luke Creagh said the program is “nothing short of outstanding,” noting the combination of grade, width and depth extensions “continues to build the case for Waihi as a third underground mine” at Davyhurst.
