Block 8 Oman: Drilling Programme and Geophysics Results

 

Power Metal Resources PLC (AIM: POW, OTCQB: POWMF), the London listed
exploration company and project incubator with a global project portfolio, and
its majority held subsidiary Power Arabia Ltd ("Power Arabia"), is pleased to
provide an update on the updated gravimetry geophysical survey results and
maiden drilling programme on the Block 8 exploration concession in Oman
("Block 8" or the "Project"), further to the Ministry of Energy and Minerals
Oman issuing a 1 year renewal of Block 8 on 30 May 2025.

Highlights:

·    Maiden reconnaissance diamond core drilling programme is scheduled to
commence on 15 September 2025, with an initial 9 drill holes planned to test
targets generated through Power Arabia's exploration work.

·    In-fill and extension gravimetry geophysics ("Gravity") survey
completed over Al Mansur Prospect.

·    Updated Gravity survey defined two strong anomalies:

o  AM1: The highest gravimetric anomaly peaking at 0.56 milligal ("mGal") of
contrast with a north south orientation that may be associated with possible
massive sulphide mineralisation (the "AM1 Target"); and

o  AM2: The second joint highest gravimetric anomaly with a similar peak of
0.56 mGal of contrast and a north south orientation that may be associated
with possible massive sulphide mineralisation or may constitute an extension
of AM1. AM2 is open on strike to the northeast.

·    AM1 and AM2 combined provide close to 700 metres ("m") of highly
anomalous target strike length at Al Mansur.

Block 8 is the subject of an Agreement for Power Metal to earn a 12.5% stake
in the Project held by ASX listed Alara Resources Limited ("Alara") and Awtad
Copper LLC ("Awtad Copper"). The exploration work, led and undertaken by the
Power Arabia technical team, commenced in October 2024 following the signing
of a formal and legally binding agreement on 25 October 2024.(1, 2)

The gravimetry geophysics method is used to measure gravitation field
variations which correspond to density changes which can be associated with
subsurface mineral deposits, such as massive sulphide, as well as geological
structures and volcanic intrusions.

Sean Wade, Chief Executive Officer of Power Metal Resources plc, commented:

"I am pleased to report on further progress at Power Arabia's flagship
project. The Gravity survey results have been encouraging, highlighting two
highly anomalous targets, and I look forward to the commencement of the maiden
drill programme, which will help enhance our understanding of the
mineralisation whilst providing an initial indication of potential width,
grade and strike related to these exciting anomalies."

Alara Managing Director Atmavireshwar Sthapak said:

"We are pleased to report that exploration activities over Block 8 have now
advanced to the critical target-testing phase through core drilling. The Al
Mansur prospect, first identified in Alara's 2012 exploration program and more
recently refined through gravity surveys, has yielded several anomalous
targets now ready for drilling.

Alara commends its partners at Power Metals for their strategic and effective
exploration efforts and remains committed to advancing exploration in Block 8.
Through planned investment alongside Power Metals, Alara also intends to
increase its stake in the joint venture. We look forward to working closely
with all our partners in the pursuit of new copper discoveries in Oman."

In-fill and Extension Ground Gravity Survey

Based on the positive findings of the Al Mansur Gravity survey (announced 17
April 2025), Power Arabia commissioned Oman based geological consultancy
National Rocks to conduct an in-fill and extension survey to better delineate
the previously defined H1 gravimetric high anomaly (now renamed AM1), with a
view to optimising drill targets for a maiden reconnaissance drilling
programme.(3)

The infill and extension work conducted during July 2025 comprised a further
348 survey points using an CG-5 Autograv Gravity Meter and a differential GPS,
on a nominal 50m x 50m grid, infilling the previous NNE orientated 100 m x 50
m grid, and extending survey coverage north and eastwards (Figure 2). The new
survey data was combined with the existing data for reprocessing and
interpretation. Both the initial survey and in-fill work was undertaken by
National Rocks to maintain operational consistency.

The Al Mansur Prospect was originally identified by Alara who conducted chip
sampling over areas of surface copper mineralisation.  Power Arabia confirmed
the prospectivity through trench sampling and geological and structural
mapping work. The Gravity survey was designed to delineate the predicted
location of possible mineralisation buried under transported overburden along
strike from the outcropping copper mineralisation located at surface on the
southern boundary of the Al Mansur prospect.(4)

The results of the Gravity in-fill and extension work have confirmed that the
previously identified H1 Target, now named AM1, is a very strong north-south
orientated Residual Anomaly on the eastern side of the survey area, which may
be associated with potential volcanogenic massive sulphide ("VMS")
mineralisation.(5)

The AM1 anomaly comprises a very high gravimetric anomaly peaking at 0.58 mGal
of contrast, whilst the newly identified AM2 target also comprises a very high
gravimetric north-south orientated anomaly of up to 0.56 mGal of contrast and
may also be associated with possible massive sulphide mineralisation or may
represent an extension of AM1.

AM2 remains open on strike to the northeast and there is now close to 700m of
highly anomalous strike length target at Al Mansur.

There is evidence of a possible northwest southeast structure in the Al Mansur
area which could mean that the AM1 and AM2 targets are part of the same
mineralised unit which may have been divided by faulting, or they could
represent two distinct bodies with the same gravimetric response and
potential.

Survey Area

Maiden Drill Programme

Further to the positive results of the ground Gravity in-fill and extension
programme, the surface copper mineralisation in the trenches and rock chips
directly on the southern limit of the AM1 anomaly, Power Arabia has planned a
maiden reconnaissance diamond core drill programme on the Al Mansur target as
a key next phase of exploration and mineralisation definition.

The drilling is planned to test for mineralisation and provide an initial
indication of potential width, grade and strike related to the identified
anomalies.

Both target anomalies are deemed to dip to the west hence drill holes are
planned to drill from west to east to ensure maximum cross cutting of the
target rather than drilling 'along' it.

The planned programme comprises an initial 9 holes for a total of 750 m of HQ
core diameter diamond drilling arranged on three broadly NW-SE orientated
fence lines (see Figure 4 and Table 1) over the AM1 anomaly (6 holes) and AM2
anomaly (3 holes). The drill holes are arranged on a heel to toe basis along
each fence line, with three holes per line planned to ensure complete drill
testing of each of the two targeted anomalies. The heel to toe concept will
also ensure the entire cross section of the anomaly is fully tested should the
dip of the target body not be as predicted; this method should also negate the
possibility of 'missing' any mineralisation present below that fence line.

Power Arabia obtained three drilling contractor quotes for the work, with the
final choice of drilling company made based on their availability, experience
and cost.

All necessary environmental and local permits have been granted to support
this programme.

Power Arabia have robust environmental and health and safety systems in place,
as do the drilling company, to ensure full compliance with all regulatory
requirements.

The programme is scheduled to commence on the 15 September 2025.

Power Arabia will provide further updates on receipt of a series assay results
for stream sediment, ionic leach, trench and rock chip samples, and continues
to expand knowledge and target identification on Block 8.

Other

In addition to the Al Mansur exploration work and drilling outlined above,
Power Arabia have next stage exploration plans for target areas 2, 4 and 5
(Figure 5) which all warrant more detailed exploration to fully test and
ascertain if more potential discoveries are present.

Power Arabia looks forward to providing further updates on this programme and
other developments on Block 8.

Figure 6 shows the current surface copper anomalies defined over the geology
and this is a key prospect for follow up exploration work to lead to a
reconnaissance drilling programme. In-fill mapping and rock chip sampling is
planned along with a tight spaced Ground Gravity Survey to help delineate a
robust drill target followed by actual drilling.

5:            Volcanic-associated or VMS deposits range from lens
shaped to sheet-like bodies of sulphide-mineral-rich rock spatially associated
with volcanic rocks ranging in composition from basalt to rhyolite. VMS
deposits can be divided into three general categories: Cyprus-type; Kuroko
type; and Besshi-type. Cyprus-type deposits tend to be small, medium-grade
deposits rich in copper and zinc. They are generally lens or mound shaped
accumulations of massive pyrite developed in ophiolite-related, extrusive
basalt sequences. They are typically underlain by copper-rich "stringer-zones"
composed of anastomosing quartz-sulphide mineral veins in extensively
chloritised basalt.
