Oracle Power plc commenced next week at the Northern Zone Gold Project, located 25 km east of Kalgoorlie in Western Australia (the "Northern Zone Gold Project"), which is being advanced by its partner, Riversgold Ltd. The Northern Zone Gold Project has an exploration target of 200Mt to 250Mt at a grade of 0.4 g/t to 0.6 g/t Au for an exploration target of 2.5Moz to 4.8Moz of gold, as announced by RGL to the ASX on the 9 May 2023. Cautionary Statement: The potential quantity and grade of the exploration target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource.

The reader is advised that an exploration target is based on existing drill results and geological observations from drilling as well as interpretation of multiple available datasets. The exploration target is based on historical and Oracle drilling results. It uses data from 53 historical drillholes drilled between 1998 and 2012, and 7 drillholes drilled by Oracle in 2021.

The contracted drill rigs are a reverse circulation ("RC") drill rig and an air core ("AC") drill rig, which will start drilling at its Northern Zone Gold Project next week, located 25 km east of Kalgoorlie in Western Australia. Refer to Figure 1 for location. On the 9 May 2023, RGL announced the 80% earn-in to the Northern Zone Gold Project with Oracle.

RGL undertook a 4-hole diamond drill programme for 1,379m (with orientated core) to specifically test the exploration model of +100m wide gold mineralisation. The RGL drilling confirmed the original mineralisation model, style, widths, and grades.
