Great Western Mining Corporation PLC Announces Upcoming Exploration Plans at Defender-Pine Crow Tungsten Project in Mineral County, Nevada USA Great Western Mining Corporation PLC update investors on its upcoming exploration plans at the Defender-Pine Crow Tungsten Project in Mineral County, Nevada USA. This follows the receipt of highly encouraging assay results at Defender announced in January 2026. Accelerating exploration activity with the objective of defining a maiden Mineral Resource Estimate ("MRE") in Fourth Quarter 2026. Assessing a 3 km long mineralised trend between Defender and the Company's existing MRE at M2, through detailed mapping and geophysical surveys commencing in March. Commencing groundwork in April to prepare drill pads, ahead of the planned start of drilling in June. Anticipating additional assay results from new channel cuts in second quarter. Great Western Chairman Brian Hall commented: "Defender is shaping up to have the potential to become a tungsten discovery of considerable scale and significance. Its geological setting, noting its proximity to Guardian Metals' Pilot Mountain Project approximately 30 miles away, reinforces confidence that are operating within a highly prospective polymetallic district. Importantly, Defender appears to represent the far eastern extension of a mineralised trend that includes M2 resource, located more than 3 km to the southwest, highlighting the potential continuity and district-scale opportunity. Two channels returned significant tungsten mineralisation, including 6 m at 0.17% WO3, including 1 m at 0.43% WO3, and 16 m at 0.30% WO3, including 2 m at 0.66% WO3. Importantly, elements that could represent potential processing penalties were recorded at very low concentrations, and silver mineralisation was also intersected within Channel B. 2026 Exploration Programme Following a successful fundraise completed in January 2026, the Company is fully funded to execute an expanded exploration programme at Defender during 2026. Accordingly, the Company has designed a programme to accelerate progress towards defining a maiden MRE, targeted for Fourth Quarter 2026, and to test the scale, continuity and geometry of the mineralised system at Defender, including its potential relationship to the broader mineralised trend extending towards M2, located more than3 km to the southwest. Detailed geological mapping and geophysical surveys will commence in March 2026 to assess the mineralised trend between Defender and The Company's existing MRE atM2. This work is intended to refine the geological model and support drill targeting initially at the eastern end of the trend. Groundworks are scheduled to begin in April to prepare the drill pads, ahead of the commencement of drilling. Bids from drilling contractors are currently being sought for the programme, with the objective of starting drilling in June 2026 and will be incorporated into the exploration model.

Great Western Mining Corporation PLC Announces the Results of an IP Geophysical Survey and the Assay Results of a Reverse Circulation Drilling Programme at Rhyolite Dome Great Western Mining Corporation PLC announced the results of an IP geophysical survey and the assay results of a reverse circulation ("RC") drilling programme at Rhyolite Dome, a previously undrilled prospect, which forms part of its Olympic Gold epithermal precious metals project in the Walker Lane trend of Nevada ("Rhyolite Dome"). Six IP survey lines completed, identifying a near-surface resistivity anomaly associated with a fault and a deeper untested chargeable feature at more than 300 m depth. Four shallow RC holes totalling 2,315 ft (706 m) intersected silicified, hydrothermally altered volcanic rocks consistent with an epithermal system. Low-grade gold and more significant silver mineralisation returned, including 70 ft (21.3 m) at 1.64 g/t Ag. Elevated pathfinder elements (Ba, As, Mn, Li, Sb) indicate shallow levels of a hydrothermal system. Geological model to be refined for better targeting of the deeper chargeable IP anomaly. Four shallow RC drill holes were completed at Rhyolite Dome in November 2025 totaling 2,315 ft (706m). Drilling primarily targeted the near-surface resistivity anomaly defined by the IP survey, while the deeper chargeable feature was ultimately beyond the effective reach of the contracted RC rig from the permitted drill pads. Drilling intercepted several intervals of silicified rhyolite with locally common pyrite, together with hydrothermally altered volcanic rock. Low concentrations of gold were encountered, with maximum intercepts of 5 ft (1.5 m) at 0.12 g/t Au and 5 ft (1.5m) at 0.11 g/t Au in hole RDRC005. More significant silver intercepts were returned, including 70 ft (21.3 m) at1.64 g/t Ag and 0.03 g/t Au in holeRDRC004, as well as 15 ft (4.6 m) at 1.13 g/t Ag and 0.,05 g/t Au. Elevated concentrations of pathfinder elements were recorded across the drill hole assays, including barium (Ba, consistently greater than 1,000 ppm), arsenic (As, consistently greater than 200 ppm and up to 3,820 ppm), manganese (Mn, with several intervals exceeding 1,000 ppm), lithium (Li, consistently greater than 50 ppm) and antimony (Sb, with various intervals above 100 ppm). These geochemical signatures are consistent with the shallow levels of a hydrother mal system. On the basis of these results, the geological framework for the Olympic Gold Project will now be revisited to refine future exploration targeting, particularly with respect to the chargeable feature that remains untested by this shallow RC drilling programme.
