Oracle Power PLC
("Oracle" or the "Company")
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 (#_ftn1) . 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.

Competent Person's Statement
The information in this announcement that relates to exploration results,
exploration targets, mineral resources or ore reserves is based on information
compiled by Mr Edward Mead, who is a Fellow of the Australasian Institute of
Mining and Metallurgy. Mr Mead is a director of Riversgold Limited and a
consultant to the Company and Oracle through Doraleda Pty Ltd. Mr Mead has
sufficient experience which is relevant to the style of mineralisation and
type of deposit under consideration and to the activity that he is undertaking
to qualify as a Competent Person as defined in the 2012 edition of the
`Australasian Code for Reporting Exploration Results, Mineral Resources and
Ore Reserves' (the JORC Code). Mr Mead consents to the inclusion of this
information in the form and context in which it appears in this announcement.
