Power Metal Resources PLC

("Power Metal" or the "Company")

Block 8 Oman: Exploration Update including 7.8% Cu Sample

 

Power Metal Resources PLC (AIM: POW, OTCQB: POWMF), the London listed
exploration company with a global project portfolio, and its majority held
subsidiary, Power Arabia Ltd ("Power Arabia"), is pleased to provide an
exploration update for the Block 8 exploration concession in Oman ("Block 8"
or the "Project").

Block 8 (Figure 1) 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 (the
"Agreement") on 25 October 2024.(1, 2)

As per the Agreement, Power Metal has reached the initial milestone of 10%
earn-in based on exploration spend to date of US$500,000 and is currently
planning the further 2.5% milestone by spending an additional US$240,000 to
attain the full 12.5% stake.

Exploration work, including rock chip sampling, mapping and in-fill
gravimetric geophysics ("Gravity") surveying, has focused on two high priority
prospects, the Al Maider Prospect and the Al Mansur Prospect, which both have
the potential to host significant mineralisation.

Highlights:

Al Maider Prospect

·    Recent rock chip sampling returns highlight copper ("Cu") results of
7.84%, 4.7%, 2.8%, and 2.7%.

·    Sample results show strong correlation of copper with an associated
structural feature.

·    Geological mapping continues to support Al Maider as a high
prospectivity target.

Al Mansur Prospect

·    In-fill Gravity survey work has defined an additional named target at
Al Mansur: the new H2 Target is located along strike to the northeast of the
previously defined H1 Target.

·    Regional Gravimetric survey results define at least 3 structural
targets in the centre of the Project.

·    Assay results from the re-analysis of trench samples, confirm the
initial positive results situated along strike from the H1 Target gravimetric
anomaly.

·    Drilling target defined.

Project Scale Exploration

·    Additional 145 Ionic leach geochemical samples to be submitted for
analysis, providing coverage for two target zones based on the gravity survey
interpretation.

·    Several targets promoted for next-stage fieldwork.

·    Full technical report submitted to the Ministry of Mines Oman in
support of the Project licence renewal process.

 

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

"These results further underpin our confidence that these two key prospects
have the potential to host significant mineralisation, whilst also
demonstrating the wider potential for Block 8 to deliver value to stakeholders
and shareholders.

"I would like to thank the Power Arabia team for their continued efforts
across a range of workstreams at Block 8, and I look forward to providing
updates on the planned exploration work we will look to undertake in order to
attain the full 12.5% stake."

Atmavireshwar Sthapak, Managing Director of Alara Resources, commented:

"We are pleased with the encouraging results from recent exploration
activities undertaken by our partners in the Block 8 exploration licence. The
Al Mansur prospect, originally discovered by Alara in 2012-13, continues to
demonstrate strong potential, having now progressed to the drill-testing stage
following recent work. The discovery of a new prospect, Al Maider, by Power
Metal further highlights the broader potential of Block 8 to host additional
copper mineralisation.

"Alara is committed to advancing the exploration of Block 8 and intends to
increase its stake in the joint venture through continued investment alongside
Power Metal. I would like to commend the Power Metal team for their strategic
and effective exploration efforts. We look forward to working closely with all
our partners in the pursuit of new copper discoveries in Oman."

Exploration Summary

Further to the initial ground Gravity survey results, announced 17 April 2025,
the recent work commissioned and undertaken by Power Arabia includes
additional in-fill gravimetric survey work and associated interpretation,
geological mapping, surface sampling and check-sampling.

Project Scale Geological Mapping

The Power Arabia technical team have commenced the detailed geological mapping
and interpretation of the entire Project area.  This work will consolidate
and cross-correlate at least five historic geological maps within the Project
area, and will provide more detailed mapping coverage for the southern region
of the Project including the Al Maider and Al Mansur prospects. The mapping
work will also entail the use of remote sensing imagery, the gravimetric
results and historical ground magnetic geophysical surveys.  The resulting
geological map (Figure 2) will greatly aid ongoing and further exploration.

Al Maider Prospect

The Al Maider Prospect was delineated from stream sediment sampling programmes
in 2024 and early 2025, with copper bearing float located in the area, leading
to the team finding the bedrock source upstream at Al Maider. The geology of
the Al Maider Prospect and the copper in stream sediment results are shown in
Figure 3.

Work to date on the Al Maider Prospect consists of a combination of geological
mapping and rock chip sampling.  The most recent sampling has yielded
significant new copper results (see Table 1 and Appendix 1) which, combined
with previous results and geological and structural fault mapping, define a
robust 4 kilometre ("km") long copper target.

With recent work concentrating on the northern part of the Al Maider Prospect,
the Company is investigating potential for further mineralisation to the
south, along strike of the Gabbro unit and 1.75% copper grab sample result
depicted in Figure 4.  Whilst this result is for a grab sample rather than an
in-situ bed-rock sample, it shows potential for localised copper
mineralisation.

Follow-up work at Al Maider will include infill mapping and sampling along the
prospect trend, trenching and a ground magnetic survey with a view to
establishing targets for initial drill testing. Access to this prospect is
quite challenging and therefore further non-invasive work will be carried out
to add confidence prior to any drilling.

highlighted red. The full sample results are shown in Appendix 1.

Figure 3: Al Maider Prospect Copper in Stream Sediment Sample Results

These rock chip sampling results and geological interpretation strengthen the
prospectivity of Al Maider with initial interpretation showing that the copper
mineralisation is associated with a gabbro intrusive 'slither' within an
ultramafic ophiolite sequence associated with a fault system (see Figure 4).

This interpretation is supported by remote sensing satellite imagery (Figure
5), which shows potential for the current project 4km strike length to be
increased subject to further on-the ground mapping.

and Al Mansur Prospects

 

Al Mansur Prospect

The Al Mansur Prospect is located in the centre of the Project area and has
been defined on the basis of trench sampling undertaken in December 2024 (3
trenches, 150 metres ("m") total length) and gravity geophysics.

Due to perceived QA/QC issues with some of the initial trench sample analysis,
Power Arabia submitted some key coarse reject sample material to a second
laboratory to verify the accuracy of the initial analysis. These returned
acceptable values slightly lower than the original results but still
confirming the anomaly of the trench.

Trench AM24TR02 returned 9m at 0.74% Cu with the trench located perpendicular
to the gravity survey anomaly H1 and the underlying stratigraphy. Trench
AM25TR04 assays results initially returned 8m at 0.29% Cu, however, due to the
lack of acceptable QA/QC as stated above, these samples were re-analysed at a
different lab, ALS Jeddah, and the results returned 8m at 0.31% Cu with
acceptable QA/QC results. This trench, which preceded more recent work, is not
perpendicular to the main strike and stratigraphy at Al Mansur Prospect.

A recent updated interpretation of the gravity survey, further to additional
in-fill and extensional survey points over the Al Mansur target (see Company
announcement 25 April 2025) has returned an additional 'H2 Target', located on
strike from the previously identified H1 Target (Figure 6).

 

Figure 6: Updated Ground Gravimetric Survey Results for Al Mansur Prospect
showing the Location of the H1 Target and New H2 Target

The processed survey data and resulting gravity-residual sections confirm that
the Al Mansur Prospect area is dominated by two pronounced positive anomalies
(H1 and H2) separated by more subdued zones of lower residuals. As shown in
Figure 7 below along Profile A-B, the residual field rises steadily from 0
milligal ("mGal") at the southern end to a broad peak of ≈ +0.45 mGal
between the two dashed markers (H1), then reverses sharply north-eastward,
falling to -0.40 mGal at the profile terminus. This asymmetric high coincides
spatially with the magenta ridge seen and marks a dense, probably
mafic/ultramafic body that is bounded on its western side by a steep density
contrast against the adjacent low-density trough L2. Profile C-D traverses the
same ridge but additionally crosses the northern high H2: a first positive
shoulder (~+0.40 mGal) associated with the southern edge of H1 is followed,
after a subtle saddle, by a sharper peak that reaches +0.60 mGal beneath the
centre of H2 before tapering northwards. The intervening slight inflection
agrees with the narrow negative corridor (blue-green colours) between H1 and
H2 on the map, suggesting a structural break or lithological change. Taken
together, the profiles demonstrate that H1 forms an elongated NW-SE dense
core, while H2 represents a separate, more localised dense block farther
north-east; both are flanked by broad gravity lows (L1-L3) that likely
represent thicker, lower-density cover sediments or alteration zones.

Figure 7: Ground Gravimetric Survey Results for Al Mansur Prospect showing all
interpreted areas of interest.

A third-party re-interpretation is planned to ensure full review is achieved
to ensure maximum confidence for an initial drill programme to test these
targets.

With the historic sampling on strike to the south and the recent trenching by
Power Arabia, this target represents the most advanced target on Block 8 with
easy access for a drilling programme.

Other Target Generation Results

The gravimetric survey also covered an area in the centre of the Project,
where it interpreted key lithological contacts and fault zones which are
considered possible mineralisation trap related targets (Figure 7).  The
initial interpretation has provided a further two strong anomalies for follow
up work.

Fault Zones

 

As advised in the announcement of 30 January 2025, 210 ionic leach soil
samples were collected but not assayed, in advance of the gravimetric survey
work. With the gravity survey interpretation now available, a subset of 145
samples, which cover the three broad target areas, have been submitted to ALS
Bijaq, Oman for laboratory analysis. The location of these samples in relation
to the gravity survey results is shown in Figure 8. Further ionic soil
sampling will be part of the next phase of exploration.

Target Areas, Central Block 8

 

Power Arabia is currently undertaking a review of the exploration results and
interpretations in preparation for the next phase of exploration to meet its
second milestone of 12.5% earn-in, having now met its initial milestone of
10%. The Project is proving highly prospective and, with the Block 8 licence
renewal now granted,  the Power Arabia technical team is excited to continue
the exploration with the objective of defining an initial drilling programme.

4:            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.
