New Shallow Gold Zone at Northern Zone Gold Project

25km East of Kalgoorlie

Oracle Power PLC (AIM:ORCP), an international project developer, is pleased to announce assay results from a further six drillholes at the Northern Zone Gold Project ("Northern Zone Project" or "Project"), located just 25km east of Kalgoorlie in Western Australia (refer to Figure 1 for location). Results from a further nine grade control drillholes are anticipated to be received shortly. Samples from 28 air core drillholes from the recently completed program have been submitted for assay, with results from all 37 drillholes expected to be received in batches over the next six weeks.

Highlights

·    Riversgold continues to keep intersecting shallow gold mineralisation at Northern Zone Project

·    Assay results from a further 6 drillholes have been received.

·    Gold mineralisation now identified in the previously undrilled "saddle" between the eastern and northwestern mineralised zones.

·    Significant results from the second batch of results include:

o  5m at 3.09 g/t Au from 47m                                                         (NZAC152)

o  6m at 0.72 g/t Au from 66m (end-of-hole)                            (NZAC152)

o  6m at 0.65 g/t Au from 32m                                                         (NZAC153)

o  1m at 11.0 g/t Au from 46m                                                         (NZAC153)

o  8m at 0.62 g/t Au from 32m                                                         (NZAC154)

o  2m at 1.47 g/t Au from 49m                                                         (NZAC155)

o  7m at 1.58 g/t Au from 42m                                                         (NZAC156)

o  2m at 1.32 g/t Au from 44m                                                         (NZAC157)

·    2025 drilling has now concluded with results from a further 37 drillholes due to be received in batches over the coming weeks.

Naheed Memon, CEO of Oracle, commented:

"Intersecting these gold grades in the previously undrilled saddle area between the eastern and the northwestern shallow gold zones is highly significant as it demonstrates the potential for these two zones to join together. Our modelling suggests that this could constitute a ~600m wide zone of shallow oxide mineralisation overlying the Northern Zone porphyry system.

"We are still awaiting results from 9 drillholes from the grade control drill rig program, and 28 vertical air core drillholes from the drilling have just been submitted to the lab. With results from these 37 drillholes expected in the coming weeks, we are looking forward to a constant stream of news-flow leading into the New Year.

"The two recently completed drill programs were designed to add to the gold footprint in the top 50-60m at the Northern Zone Project, and to enhance the MEGA Resources mining scenario for 2026[1]. Results continue to expand the lateral footprint of Northern Zone and we are achieving the goal of making the Project bigger in the oxide zone. I look forward to updating shareholders as we progress the Project."

The latest drill programs (Tables 1-3) continue to successfully intersect the mineralised host porphyry over an increasing footprint and consistently validate the broader gold mineralisation model. Gold mineralisation has been successfully intersected in a previously undrilled area referred to as the saddle with modelling suggests the potential of joining the northwestern and eastern mineralisation. The last drillhole on the eastern extension intersected significant gold mineralisation (see Figure 2), with the overall footprint expanding. A key SW-NE cross-section derived from 3D Leapfrog software is illustrated in Figure 3. The interpretation illustrates gold grade shells derived from all the significant intercepts reported to April 2025. The Leapfrog model will be updated once all pending assays are received.

Northern Zone is hosted within a porphyry unit (Tonalite-Trondhjemite Intrusion, TTI), with high background gold and horizontal gold mineralised units within the TTI unit. The Northern Zone Project sits within the Canon Shear or fault zone, with further drilling required to define the limits of mineralisation identified to date. The horizontal mineralisation makes drilling to date perpendicular to the gold mineralisation, and no water in drilling to a depth of 60 metres makes the TTI also suitable for drilling with the techniques the Company has utilised to date.

Riversgold will continue advancing its understanding of the Project before proceeding with a maiden Mineral Resource Estimate (MRE), but this drilling will be used by Mega Resources in their mine planning for our joint plans to start mining in the first half of 2026.
