("Oracle" or the "Company")
Gold Results Continue to Expand the Footprint at Northern Zone Gold Project
Oracle Power PLC (AIM: ORCP), an international project developer, is pleased
to announce assay results from the first six drillholes of the recently
completed vertical Grade Control ("GC") drilling programme at the Northern
Zone Intrusive Hosted Gold Project ("Northern Zone" or the "Project"), located
25km east of Kalgoorlie in Western Australia (refer to Figure 1 for location).
Assay results from a further 15 drillholes are still to be assayed, with
results expected in the near term. In addition, drilling is progressing on a
new ~40-hole drilling programme, with 12 holes completed to date.
Highlights
· The Company continues to expand the gold mineralisation footprint at
the Northern Zone.
· Assay results from the first six holes of a 21-hole programme have
been received.
· Significant results from the first batch of results from
pre-Christmas drilling include:
o 9m @ 1.33 g/t Au from 56m,
(NZAC146)
o 3m @ 4.39 g/t Au from 45m,
(NZAC149)
o 3m @ 1.89 g/t Au from 48m,
(NZAC150)
o 5m @ 1.75 g/t Au from 61m (EOH),
(NZAC150)
o 4m @ 0.83 g/t Au from 47m,
(NZAC151)
· Targeted drilling continues, with the current campaign 12 holes into
a further 40-hole programme with results to be reported in the next six to
eight weeks.
Naheed Memon, CEO of Oracle, commented:
"As highlighted before, we planned to undertake two drill programmes before
the end of the year to add to our gold footprint in the top 50-60 metres at
our Northern Zone gold project, and to enhance the MEGA Resources mining
operations scenario for 2026. The results from this first batch of assay
results continue to expand the lateral footprint of the Northern Zone and we
continue to achieve the goal of making the project bigger in the oxide zone.
"Everything is going to plan as we expand the mineralised footprint of the
Project and define the high-grade gold zone hosted within a large lower-grade
porphyry host. The reported results continue to meet and exceed expectations,
with the new high-grade zone being delineated on the eastern margin of the
Project, now looking to move northwards.
"The second shallow drill programme is well underway with more samples now in
for assay, and we expect to report these assay results over the next six to
eight weeks."
Results from the GC programme (Tables 1-3) continue to successfully intersect
the mineralised host porphyry over an expanding footprint, consistently
supporting the broader gold mineralisation model. Five drillholes on the
eastern extension intersected significant gold mineralisation (see Figure 2),
with the footprint expanding northwards. 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
announced by the Company 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.
The Northern Zone JV 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.

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 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.
