("Oracle" or the "Company")
Further Assay Results from the Northern Zone Gold Project
An additional 1,756 samples are awaiting assay, with the results received to
date continuing to confirm high grade gold intercepts within a lower grade
gold halo
Oracle Power PLC (AIM:ORCP), an international project developer, is pleased to
announce that following the results of the initial two drill holes released on
19 March 2025, it has received assay results from a further five reverse
circulation (RC) drill holes, four of which are highlighted below, from the 11
hole 1,289 metre programme recently completed at the Northern Zone Intrusive
Hosted Gold Project ("Northern Zone"), located 25 km east of Kalgoorlie in
Western Australia (refer to Figure 1 for the location).
A further 1,303 samples from a 1,805 metre vertical drill programme have been
submitted to the laboratory with results expected over the coming weeks.
Accordingly, a total of 36 drill holes for 1,756 samples are currently
awaiting assay at the laboratory.
Highlights:
o Significant shallow gold intercepts from four of the RC drill holes are
reported as follows:

(NZRC012)
§ 7m @ 0.66 g/t Au from

(NZRC013)
o A further 453 samples from four RC drill holes are still to be reported
o 1,303 samples have been submitted to the assay laboratory from 32 AC drill
holes targeting the oxide mineralisation
o The results of recent drilling continue to confirm and enlarge the shallow
gold mineralisation associated with the Northern Zone porphyry
o The dynamic Leapfrog gold model for Northern Zone will be updated with these
latest results in the coming weeks, which will inform the and guide future
drill campaigns
Naheed Memon, CEO of Oracle, commented:
"These latest results complement the previous results, and those released
since late 2023, as we increase the footprint of the gold mineralisation. The
results continue to meet or exceed our expectations, revealing good tenor
within the shallower oxide gold mineralisation at the top of the mineralised
porphyry. We have a total of 1,756 samples in the lab awaiting assay from 36
drill holes to be reported in due as we continue to advance the Northern Zone
project."

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.
