Ora Banda Mining Limited announced an updated underground Mineral Resource for the Riverina Project, a key part of the Davyhurst Gold Project ("Project") located 48km north of the Davyhurst processing plant. The underground Mineral Resource has increased 46% to 728Kt @ 5.9 g/Au for 139,000 ounces, (and incorporates a 37% increase in underground gold grade). The open pit Mineral Resource remains unchanged (3.0Mt @ 1.9 g/t for 183,000 Au oz1). Collectively the total Mineral Resource at the Riverina Project has increased by 16% to 3.7Mt @ 2.7 g/t for 322k Au ounces. The company's total Mineral Resource now stands at 23.3Mt @ 2.7g/t Au for 2.05M ounces. Gold mineralisation plunges to the south and is hosted within two sub-parallel, sub-vertical shears separated by a distance of 5 to 15 metres. Drilling has demonstrated a strike of greater than 1km and at depths of up to 270m below surface. The updated underground Mineral Resource follows further modelling of Riverina Main Lode beneath the AUD 2,400 optimised open pit shell used to constrain the Riverina open pit resource. Historical underground mining of the Main Lode at Riverina was via a number of shafts, producing 99,500t @ 15.8 g/t Au for 50,490 ounces. The open-pit component of the Riverina Mineral Resource is reported from the Localised Uniform Conditioning (LUC) model within a AUD 2,400 optimised pit shell. The underground component of the Riverina Mineral Resource is reported from the updated underground Mineral Resource model and includes all blocks outside and below the same AUD 2,400 optimised pit shell but with a cut-off grade of 2.0 g/t Au, reflecting the increased cost of underground mining. A mining study aimed at defining the portions of the resource that are economically viable by underground mining is in progress. Riverina has an open pit reserve of 1.4 Mt @1.8g/t Au for 81,000 ounces6. Additional deep drilling is planned for Riverina Main lode aimed at upgrading the resource categories and to define extensions down plunge to the south. Environmental studies required for the mining approval process are also advancing.
