Further Positive Results from Kalgoorlie Drilling Programme

Oracle Power PLC (AIM:ORCP), an international project developer, is pleased to announce assay results from a further 21 drillholes at the Northern Zone Intrusive Hosted Gold Project, located within the Company's Kalgoorlie Gold Project (refer to Figure 1 for location). The values from selected drill holes are given in Tables 1-3 and in Figure 2.  Results from a further 16 drillholes are anticipated to be received shortly.

Highlights

·    The drilling programme has continued to intersect shallow gold mineralisation as drilling expands the gold footprint at the Northern Zone Gold Project.

·    First assay results now arriving for 2026, with significant results, including:

·    8m @ 5.81 g/t Au from 46m         (NZAC179)

·    7m @ 3.48 g/t Au from 48m         (NZAC181)

·    5m @ 3.13 g/t Au from 41m         (NZAC170)

·    4m @ 2.28 g/t Au from 43m         (NZAC182)

·    Further significant results shown in tables below

·    Drilling results from a further 16 drillholes due to be received in two batches over the coming weeks.

·    Drill rig booked for 10 February aiming to continue expanding the oxide gold mineralisation footprint.

·    Conversion to Mining Lease process continues with the Heritage Agreement a major step forward.^[1]

·    The Mine Development and Closure Plan (MDCP) and the associated environmental assessments have commenced with Resource WA.

Naheed Memon, CEO of Oracle, commented:

"It is great to follow on from previous announcements and continue to expand and intersect gold grades in the northeast area and expand the saddle area. We believe these results are very impressive and add significant upside to the project for our plans with our partners for gold production targeted for later this year.  Our modelling suggests that this could constitute part of a ~600m wide zone of shallow oxide mineralisation overlying the Northern Zone porphyry system.

"Oracle also notes from Riversgold's news release on the ASX today that MEGA Resources has become a shareholder of Riversgold, and we see this as highly promising for the JV partnership going forward.

"We are still awaiting results from 16 drillholes, expected in the coming weeks, and we are looking forward to the assays that will be from the northeast and saddle areas.

"The two recently completed drill programmes were designed to add to our gold footprint in the top 50-60m at our Kalgoorlie Gold Project, and to enhance the MEGA Resources mining scenario for 2026^[2]. 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 programme results (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 the northeast area, with a section of drill holes to the north of an existing single line, expanding the gold mineralisation footprint (Figure 2). More drill results from the saddle area between the west and east zones is filling in nicely, with a further 12 holes due shortly. 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 by Riversgold 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 Kalgoorlie 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.
