Block 8 Oman: Drilling Programme 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"), are pleased to provide an update on the maiden drilling programme on the Block 8 concession in Oman ("Block 8" or the "Project").

Highlights:

·   Maiden reconnaissance diamond core drilling programme completed in October 2025, with eight drill holes for a total meterage of 724.45 metres ("m") drilled.

·   Identified lithological units, alteration, brecciation and mineralisation consistent with copper-dominant (Cyprus-type) Volcanogenic Massive Sulphide ("VMS")1, 2.

·   All holes intersected prospective lithological units, including basalt and andesite with associated carbonate, chlorite and epidote alteration.

·   Highlight downhole depth intercepts of:

·   1.04% Copper ("Cu") over 1.5m (hole AM25DD001 from 95.5-97m within wider zone returning 0.52% Cu from 95.5-99.0m);

·   0.36% Cu over 1m (AM25DD001 from 72-73m, within a broader elevated Cu zone from 68-77m);

·   0.35% Cu over 4m (AM25DD001 from 80-84m, with up to 0.56% Cu from 80-81m);

·   0.19% Cu over 4m (AM25DD002 from 85-89m);

·   Elevated Cu, lead ("Pb") and zinc ("Zn") results over 18 m (AM25DD003 from 35-53m, associated with a sulphide stockwork in a fault zone); and

·   1.1% Zn over 1m (AM25DD006 from 51-52m, plus elevated Cu and Zn from 51-58m).

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 2024.3, 4

The drilling programme completes the initial 12.5% earn-in.

 

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

"The results of the maiden drilling programme are very encouraging and confirm our view that this is a prospective area that has been under-explored. The completion of the programme marks the fulfilment of the agreed $740,000 spend to earn a 12.5% stake in Block 8.

"I look forward to updating the market further as we move into the next phase of workstreams with additional trenching and drilling programmes that will enhance our understanding of the results and the mineralised intersects."

Atmavireshwar Sthapak, Managing Director of Alara Resources said: 

"We are very encouraged by the results of this maiden drilling programme at Block 8. The identification of VMS-style mineralisation, strong alteration signatures and structural features across all drill holes confirms the robustness of the geological model developed through the Power Metals exploration work. These early results highlight the potential of Block 8 to host Cyprus-type copper mineralisation, and they provide a solid foundation for advancing the next phase of exploration.

We look forward to continuing our collaboration with Power Metal and Awtad Copper as we build further momentum on this promising project."

Block 8

Block 8 is located approximately 130 kilometres ("km") west of Muscat in Oman and encompasses a contiguous area of 497 km2 (Figure 1). The concession includes a section of the Semail Ophiolite that is prospective for copper-dominant (Cyprus-type) VMS mineralisation. Power Arabia's exploration activities have included spectral remote sensing, stream sediment, soil and rock chip sampling, trenching and sampling, gravimetric surveying, petrography and X-Ray Diffraction ("XRD") analysis.

Drilling programme

The initial drilling targets were mainly based on geological observations, magnetic and gravimetric data, and trenching results. However, the locations were ultimately adjusted in response to observations as the programme, which contained eight holes totalling 724.45m, developed.

The drillhole locations and parameters are shown in Figure 2 and summarised in Table 1 respectively.

Drillhole observations

The drilling intersected a volcanic succession predominantly consisting of intercalated andesite and basalt units. Andesite units ranged in thickness from 0.12 to 11.1m (averaging 3.22m), and basalt units ranged in thickness from 0.13 to 12.95m (averaging 2.0m). Some of the basalt units included pillows, substantiating subaqueous deposition and favourable genetic conditions for the formation of massive sulphide mineralisation.

Propylitic alteration, including carbonate, chlorite and epidote, was apparent in almost all drillholes and particularly associated with basaltic units.

Faulting and brecciation were also common and evident in all drillholes. Breccias ranged in thickness from 0.2 to 13.5m (averaging 3.82m) and some were associated with alteration (silica, carbonate, chlorite, epidote and hematite).

Significant sulphides, mainly pyrite, were intersected in six of the eight drillholes. The pyrite occurred as disseminations, veinlets and in semi-massive form (Figures 3-5).

Figure 4: Brecciated and Colloform Pyrite in Drill Core (AM25DD001 from 95.5m)

Figure 5: Semi-massive Pyrite and Quartz Breccia/Stockwork Drill Core (AM25DD003)

Pyrite mainly occurred within the andesite and basalt units and in the presence of propylitic alteration, although some of the faults and breccias also included pyrite disseminations and veinlets.

Drillhole sampling and results

A total of 156 half-core samples were cut using a diamond saw with 11 Quality Assurance ("QA") samples distributed throughout the batch. All samples were prepared and analysed by ALS Arabia Biyaq in Oman.

Drillhole AM25DD001 included up to 1.04% Cu over 1.5m (from 95.5-97m downhole depth) corresponding to faulted dolerite within a wider zone returning 0.52% Cu over 3.5m (from 95.5-99m). Other intersections included 0.36% Cu over 1m (from 72-73m) and 0.35% Cu over 4m (from 80-84m). Half of the samples from the drillhole (36 of 72) returned Cu values > 100 ppm Cu (the average abundance for basalts5) and correspond to elevated iron z-scores (z-scores indicate how many standard deviations a result is from the mean of a distribution and is used to assess anomalous values).

Drillhole AM25DD002 included up to 0.19% Cu over 4m (from 85-89m downhole) in basalt.

Drillhole AM25DD003 included up to 0.18% Cu over 1m (from 42-43m downhole) within a stockwork zone.

Drillhole AM25DD006 included up to 1.1% Zn over 1m (from 51-52m downhole).

Tabulated drillhole results are provided in Table 2 below.

Sections for drillholes AM25DD001 and 2, and AM25DD003 and 8 are shown in Figures 6 and 7 respectively.

Conclusions

The drillhole observations and results identified some significant sulphide mineralisation in what is interpreted to be the peripheral zone of a mineralised system. The >1% Cu intersection in hole AM25DD001, along with the other geochemically anomalous zones, offer great encouragement and targets for the next phases of work.

The next phases of work include a full review of all results to better understand the geological associations with mineralisation, with an emphasis on the breccia units. This would facilitate the planning of a follow-up trenching and drilling programme.

Some additional sampling on the remaining core is also planned. This includes sampling the rest of AM25DD006, hole AM25DD007 (located over 1km to the north of hole AM25DD001), as well as potentially some intervals of the as yet unsampled holes AM25DD004, 5 and 7 (that contain alteration and some observed mineralisation).

NOTES TO EDITORS

Power Metal Resources PLC (AIM: POW, OTCQB: POWMF) is a London-listed metals exploration company which finances and manages global resource projects and is seeking large scale metal discoveries.

 

The Company has a principal focus on opportunities offering district scale potential across a global portfolio including precious, base and strategic metal exploration in North America, Africa, Saudi Arabia, Oman and Australia.

 

Project interests range from early-stage greenfield exploration to later-stage prospects currently subject to drill programmes.

 

Power Metal will develop projects internally or through strategic joint ventures until a project becomes ready for disposal through outright sale or separate listing on a recognised stock exchange thereby crystallising the value generated from our internal exploration and development work.

 

Value generated through disposals will be deployed internally to drive the Company's growth or may be returned to shareholders through share buy backs, dividends or in-specie distributions of assets.
