Mining and Co-Operation Agreement with Mega Resources

Northern Zone Gold Project

MEGA Resources will fully-fund the operations with Project Owners to receive 50% of the profit

Oracle Power PLC (AIM:ORCP), an international project developer, is pleased to announce that Oracle (through its Australian subsidiary) and Riversgold Limited ("Riversgold")  have agreed a binding Right to Mine and Co-Operation Agreement with MEGA Resources Pty Limited ("MEGA Resources") and Bain Global Resources Pty Limited ("BGR Pty") for the right to mine (the "MEGA Resources Agreement") with respect to the Northern Zone Gold Project ("Northern Zone") located 25km east-south-east of the Kalgoorlie Super Pit in Western Australia. Figure 1.

Highlights:

·    The Northern Zone is owned 80% by ASX listed Riversgold and 20% by Oracle ("Project Owners") as set out in the Earn-in Agreement between the Project Owners in May 2023, with the JV agreement to be documented by 31 December 2025 latest.

·    Riversgold has signed on the Project Owners behalf, a Right to Mine and Co-Operation Agreement with established WA Goldfields mining services provider MEGA Resources   for full project funding, mining, and haulage services at its Northern Zone.

·    MEGA Resources is a full-service mining contractor that will now be providing all of the funding for the operation, through BGR Pty; MEGA Resources will also provide geological and engineering services and manage project approvals.

·    Mega Resources has a partnership with mining giant BGR Mining & Infra Limited, which owns BGR Pty, and which will provide funding for mining operations at the Northern Zone.

·    No upfront funding is required from the Project Owners.

·    MEGA Resources and BGR will share profits equally (50/50) from operations with the Project Owners.

·    10% of monthly profits (funded on a 50/50 basis) will be reinvested back into grade control and step out drilling.

·    MEGA Resources is aiming to break ground during the first quarter of 2026, subject to the Project Owners gaining all the final tenement permissions, mining approvals and the signing of a binding Ore Purchase Agreement with a third-party processing mill.

·    The Northern Zone drilling has already identified a gold mineralised porphyry around 600m wide and around 500m deep from diamond drilling^[1].

·    New Northern Zone drilling programmes are being planned to test extensions of known gold mineralisation.

Under the MEGA Resources Agreement, MEGA Resources and BGR Pty will pay for 100% of the costs to develop and mine at the Northern Zone, including paying for all ancillary activities (which incorporates haulage of material to the point of sale, maintenance of haul roads and processing costs).

In return for MEGA Resources paying for all of the upfront costs at Northern Zone, any profit generated from this partnership will be split 50%/50% with the Project Owners.

In May 2023, Oracle and Riversgold signed an earn-in agreement with and Riversgold immediately embarked on a drilling program with first results announced in August 2023. In February 2025, Riversgold exercised its option to acquire an 80% interest in the Northern Zone with Oracle retaining the remaining 20%. Oracle's holding will remain unchanged with the MEGA Resources Agreement.

Naheed Memon, CEO of Oracle, commented:

"This is an outstanding deal for Oracle as it accelerates the mining of prospective gold deposits and removes the funding requirements on Oracle whilst providing a share of potential profits at our Northern Zone Kalgoorlie Gold Project. MEGA are aiming to have their mining team on site early next year. Further details of the partnership's plans will be made available to shareholders closer to breaking ground. We plan to continue our drilling efforts on the shallower gold mineralisation and expand on the gold zones already identified. Oracle is highly optimistic for the long-term future of this project."

About Northern Zone Gold Project

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 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 the techniques Riversgold has utilised to date.

Metallurgical test work using cyanide bottle roll has closely replicated the original 2023 work previously reported, when Riversgold completed due diligence on the project. The results between 90.64% and 94.7% for five samples, average 92.56% gold recovery^[2]

A select sample of the many drill results reported to date are listed below:^[3][4]

The geological model, and previously announced Exploration Target at the Northern Zone Gold Project remains valid, with a range of 200Mt - 250Mt at a grade of 0.4 g/t Au - 0.6 g/t Au for an Exploration Target of 2.5Moz - 4.8Moz of gold.^[5]
