The Riverina Project area is located approximately 48 km north of the Davyhurst Processing Plant. The project comprises gold resources defined at the Riverina, Silver Tongue, Forehand and Sunraysia deposits, as well as several advanced exploration targets. The main Riverina deposit is one of five key priority mining targets at the Davyhurst Gold Project. It’s high proportion of oxide tonnes make it an attractive early source of ore. There is an existing haulage road in place between Davyhurst and Riverina.
GEOLOGY & MINERALISATION
The Riverina deposit occurs as a series of mineralised shears within a package of mafic and ultramafic volcanic and metasedimentary rocks. The mineralisation is well-defined over a strike of approximately 1.2 km and remains open along strike and at depth. OBM has reached agreement with the Riverina Station owners to remove a historical exclusion zone surrounding the homestead which opens an additional 1.0 km of strike extension to the south of the known mineralisation.

Previous companies have established the potential of the site for open cut operations. OBM has recently completed additional infill RC and diamond drilling, confirming the existing Riverina resource, and are now working on finalising a revised mine plan. In addition, the company intends to test below and down-plunge of the historic underground workings as a source of high-grade underground ore.
Silver Tongue and Forehand Deposits: These deposits are approximately 1 km east of the Riverina Deposit and within a similar rock sequence. The deposits are on granted mining leases. Additional drilling is required on each deposit prior to updating the resource estimates.
Sunraysia Deposit: Is approximately 5 km south of Riverina within a similar geological sequence. Further infill RC drilling is required to fully evaluate the deposit.
Other targets have been identified within the project area that required follow up evaluation.
