North Berwick, Scotland--(Newsfile Corp. - September 18, 2025) - WESTERN GOLD EXPLORATION LTD. (TSXV: WGLD) (the "Company") is pleased to announce results from 2025 drilling at Ardlochan (Figure 1). Following positive indications from the initial shallow scout drilling campaign at Ardlochan in 2023/24 (see May 2024 Press Release), the Company completed 741 m of drilling across three holes (Table 1). These tested three target styles: a porphyry-breccia pipe, porphyry stock mineralisation, and a marginal structural zone (Figure 2).
Breccia Pipe Gold Discovery
Drilling confirmed the discovery of a gold mineralised breccia pipe system at least 140m in diameter, containing multiple generations of porphyry breccia (Figure 3). Most of the higher-grade gold mineralisation occurs in late stage breccias with a potassic matrix and within dykes, although their development in this drillhole is limited. Further drilling is warranted to assess how the pipe varies with depth. Copper mineralisation is elevated throughout but does not correlate well with gold.
The entire pipe is anomalous in gold and averages 195m @ 0.36 g/t Au, from 30 m downhole (using a 0.1 g/t Au cutoff). Full intercepts are reported in Table 2 with higher grade zones including1:
- 4m @ 6.73 g/t Au from 135m, including:
- 1m @ 23.6 g/t Au from 136m
- 12.2m @ 0.72 g/t Au, from 31.8m*
- 6m @ 0.73 g/t Au, from 71m*
- 1m @ 1.11 g/t Au, 22.4 g/t Ag, 0.45% Cu, from 112m

"The Lorne Project continues to surprise us. Breccia pipe systems can be important hosts to gold and copper mineralisation in porphyry systems, and this pipe is consistently mineralised, with some high-grade gold in the first drillhole into the system," said Harry Dobson, Chairman. "Having identified several other potential breccia pipes, these results give us confidence in the broader potential of the project considering the limited drilling conducted to date."
The second hole, WGLD25-B, drilled towards the top of a resistivity magnetic target, looking for primary porphyry mineralisation. It intersected minor copper (up to 0.33% Cu) and gold (up to 0.27 g/t Au) at the granodiorite contact with the phyllite country rock over several metres. The magnetic anomaly appears to be caused by potassic veining with associated magnetite within the granodiorite, but is essentially barren, downgrading this geophysical target. Mineralisation of interest includes*:
- Skarned Dalradian metasediments with biotite-feldspar porphyry dykes:
- 9m @ 0.18 g/t Au [from 17m], including 1m @ 0.53 g/t Au
- Dalradian - granodiorite contact:
- 7m @ 0.14% Cu, 0.17 g/t Au [from 100m]
- Veined granodiorite:
- 1m @ 0.33% Cu, 0.05% Mo, 0.27 g/t Au [from 114m]
*Using a 0.1 g/t Au cut-off with <= 5m consecutive internal dilution
The third hole, WGLD25-D2, tested the structural target but did not intercept the first structural zone, as it was stoped out by later Tertiary dolerite dykes. The MT survey's conductive target zone was intersected and is represented by pyritic granodiorite/monzonite with minor chalcopyrite, associated with potassic alteration; this interval is weakly enriched in copper (c. 200-500 ppm Cu). Drilling terminated in this weakly mineralised and altered zone, characterised by quartz-K-feldspar-biotite veining with minor actinolite and molybdenite.

Next Steps
Drilling has confirmed Ardlochan has potential for gold rich porphyry style mineralisation and validated that anomalies from the 2024 airborne MT survey align with key geological features. Late potassic mineralisation identified within the breccia pipe tested in hole WGLD009_EXT has been identified as a key target for future exploration efforts. Historic maps created by a Noranda Phelps Dodge joint venture during the discovery of the Ardlochan area have been recently recovered from the British Geological Survey MEIGA reports and are currently being reanalysed and assessed on the ground by our team of geologists. New exploration targets, with a focus on gold-rich porphyry-breccia's, are currently being refined.

Review by Qualified Person, Quality Control and Reports
David Pym (CGeol), a consultant of the Company, is the Qualified Person (as defined by National Instrument 43-101) who supervised, verified and approved the scientific and technical disclosure in this press release on behalf of the Company. Verification included checking a proportion of the reported assays (excluding historical) in the Company database against the issued laboratory assay certificates. In addition, verification has included checking the location and orientation of the drill collars in the Company database against historic maps and reports.
The Qualified Person has not reviewed the mineral tenure, nor independently verified the legal status and ownership of the Property or any underlying property agreements. The drilling was conducted by specialist contractor Mineral Exploration Drilling Ltd (MED) using a small footprint drill rig. Collars were surveyed using multi-band GNSS for precision positioning, and downhole surveys were measured using a Reflex GYRO survey tool. Holes were drilled using HQ diameter core barrels positioned approximately perpendicular to the interpreted orientation of drill-targets. All core was orientated and recoveries were generally > 95% beneath overburden. All core was logged, photographed, split to half-core and sampled at the Company's onsite technical facilities. Intercept widths are not true widths and are subject to ongoing interpretation. All drill core was shipped directly to ALS Loughrea, IDA Business Park, Dublin Road, H62 PN80, Loughrea, Co. Galway, Ireland, for analyses. The Company can guarantee the chain of custody. Gold was assayed by 30g fire assay analysis with AAS finish (Au-AA23). Base metals and silver were analysed using four-acid digestion ICP-MS (ME-MS61). All ALS Geochemistry sites operate under a single Global Geochemistry Quality Manual that complies with ISO/IEC 17025:2017, coupled within a global LIMS platform. There is no relationship, fiduciary or otherwise, between ALS and the Company. The Company's QA/QC program for drill core samples includes the regular insertion of blanks and standards into the sample shipments, as well as instructions for duplication. Standards and blanks are inserted every 20 samples.
