Full Summary

Ora Banda Mining Ltd (ASX: OBM) is pleased to report a new Mineral Resource of 25.6Mt @ 1.6g/t for 1,330 koz at the Company's Round Dam deposit - a 964% increase from the previous resource of 125 koz. The 25.6Mt Round Dam Resource includes 7.2Mt at 1.8g/t for 408 koz in the Indicated category and 18.2Mt at 1.6g/t for 922 koz in the Inferred category. All of the Round Dam Resource is considered suitable for open pit mining and has been calculated with open pit shells that are cash-flow positive at A$5,000/oz, using a cut-off grade of 0.3g/t. The resource estimate includes drilling up to the end of January, noting that it remains open along strike and at depth, with follow up drilling for both resource extension and category conversion continuing. The resource uplift at Round Dam provides a substantial boost to the Company's total global resource position which has increased by 57% to 3.3 Moz - noting that further resource updates are planned to be released for other deposits in mid-2026. Ora Banda has budgeted to spend $73 million on exploration in FY26 which equates to approximately 330km of drilling. Ora Banda considers exploration along the Round Dam trend still to be at an early stage, with the 18km long north-south striking mineralised trend running from Waihi in the north (3.5km from the Davyhurst Mill) to Salmon Gums in the south.

Outlook

Ora Banda is incredibly excited by the potential of Round Dam to become a substantial mining operation, as the Company continues to advance its study work into the construction of a standalone ~3mtpa processing facility at Davyhurst.
