Photograph of cut half HQ3 drill core from 184.5m to 186.0m in 26WCDD029 showing the high grade silver mineralisation (1.5m @ 1,039g/t Ag) in pyroxenite host rock in the newly interpreted mineralised zone offset from the Munni Munni Fault. Yellow arrows point to fine grained (<1mm) silver mineralisation. West Coast Silver Limited (ASX: WCE) (‘West Coast Silver’ or the ‘Company’) is pleased to report it has received results from diamond drilling with high-grade silver and base metal intersections. The Company has also received significant assay results for the last 15 of 32 reverse circulation (RC) drill holes completed in May 2026 at the Elizabeth Hill Project (WCE 70%, Alien Metals 30%), located near Karratha in the Pilbara region of Western Australia. The 32 RC hole program (2,710m) targeted silver mineralisation north of the April 2026 maiden Mineral Resource Estimate (MRE), with results to date indicating significant extensions beyond the current resource envelope. Diamond drilling continues to test for extensions to, and infill of, the MRE, while economic studies of near-surface mineralisation are progressing towards a Scoping Study. Refer to previous ASX Announcements from the Company regarding details of previous exploration results included in this announcement. Executive Chairman Bruce Garlick commented: "We are excited by the outcomes of these diamond and RC drilling campaigns at Elizabeth Hill and Elizabeth Hill North. The identification of high-grade silver at depth in 26WCDD029 (3m @ 524g/t Ag from 183m; including 1.5m @ 1,039g/t Ag from 184.5m) and broad, near-surface silver zones of up to 44m downhole extent, together with mineralisation extending beyond the current resource boundary, demonstrates the increasing scale of the Elizabeth Hill silver system and reinforces its significant resource growth potential. The extension of mineralisation beyond the April 2026 MRE, to the north, west and at depth, has the potential to add new silver ounces and tonnes in the next MRE update. Importantly, the intersection of silver mineralisation hosted in granite expands the prospectivity of the system beyond a single rock type, and the alteration patterns observed provide the exploration team with a robust tool for targeting higher-grade zones. The intersection of nickel (Ni), copper (Cu) and palladium (Pd) in 26WCDD029 (0.45m @ 2.73% Ni, 0.93% Cu and 0.7g/t Pd from 154.87m) hosted in ultramafic lithologies within the basal Munni Munni Intrusive Complex, opens the possibility of an additional mineralisation style at Elizabeth Hill. The Elizabeth Hill trend remains open to the north and at depth, and we look forward to updating shareholders as further assay results are received over the coming months.” ASX:WCE ANNOUNCEMENT 9 July 2026 WEST COAST SILVER LIMITED ASX | WCE Page 3 DIAMOND DRILL RESULTS Elizabeth Hill Deeps Diamond drill hole 26WCDD029 (Figure 2, Figure 3, Figure 4) was drilled targeting the potential continuation of high-grade silver mineralisation intersected in historical drilling from underground to the south and below the Elizabeth Hill Mine workings (UGD084: 7m @ 607g/t Ag from 57m2 ; including 2m @ 1,995g/t Ag from 61m3 ). 26WCDD029 intersected 3m @ 524g/t Ag from 183m; including 1.5m @ 1,039g/t Ag from 184.5m downhole depth (Figure 1). This intersection is 12m to the south of the UGD084 intersection. These drill intersections form part of a 50m long north-south, sub-horizontal, mineralised trend at depth beneath the mine workings that also includes a historical intersection of 4m @ 223g/t Ag from 190m in drill hole AG33, as well as other anomalous drill intersections with silver in the 5-50g/t Ag range. This mineralised trend is on the contact between granite and ultramafic rocks that sit to the east, and offset, from the main Munni Munni Fault Zone (MMFZ). Previous drilling has concentrated on testing the vertical MMFZ in this area and as a result this target trend is poorly drilled with most of the holes passing above this sub-horizontal trend to penetrate the MMFZ to the west. Controls on this trend are poorly constrained. There is potential for more mineralisation hosting/controlling, structural splays sub-parallel to the MMFZ intersecting the granite-ultramafic lithology contact east of the main MMFZ. Where hole 26WCDD029 passed through the MMFZ at depth it did not encounter any significant silver mineralisation. Other deep drilling around the MMFZ in holes 26WCDD026 and 26WCDD028 (Figure 2, Figure 3, Figure 4) returned intersections anomalous in silver within the MMFZ. The most significant of these was 1m @ 18g/t Ag from 210m in hole 26WCDD026. 26WCDD028 did not return any significant assay results. 26WCDD026 was drilled to test the MMFZ at depth south of the mine workings, and is the southernmost hole drilled by WCE to date. 26WCDD028 was drilled to test the MMFZ at depth beneath the mine workings. Hole 26WCDD027 (Figure 2) was drilled to target the borehole electromagnetic (BHEM) conductivity anomaly modelled from the BHEM survey conducted in hole 25WCDD025 in April this year. It did not intersect any significant mineralisation to explain the conductivity model. However, the hole did intersect a broad section of anomalous copper (individual assays ranging from 0.11% to 0.45%), coincident with trace sulphides in ultramafic rocks from 34m to 56m downhole depth. Drill hole 26WCDD029 also intersected massive sulphides from 154.87m with 0.45m @ 2.73% Ni, 0.93% Cu and 0.7g/t Pd, hosted in ultramafic lithologies within the basal Munni Munni Intrusive Complex (MMIC) igneous suite. Historical underground drill hole UGD085 in this area intersected sulphide mineralisation (1m @ 2.33% Ni, 0.6% Cu from 52m4 ) also within ultramafic rocks on the contact with the granite. These intersections are in the vicinity of the BHEM conductivity anomaly identified in 25WCDD025 that was remodelled with information from 26WCDD027. This strongly suggests the conductivity feature relates to similar sulphides in ultramafic rocks of the MMIC. 2 Using 10 g/t Ag cut off on assay data contained within Appendix 2 of ASX Announcement dated 9 October 2025. 3 See Appendix 2 of ASX Announcement dated 9 October 2025 4 See Appendix 2 of ASX Announcement dated 9 October 2025 ASX:WCE ANNOUNCEMENT 9 July 2026 WEST COAST SILVER LIMITED ASX | WCE Page 4 Figure 2.

Elizabeth Hill Deeps diamond drilling longitudinal section view ASX: WCE ANNOUNCEMENT 9 July 2026 WEST COAST SILVER LIMITED ASX | WCE Page 8 RC DRILL RESULTS Elizabeth Hill North Assay results from the final 15 of 32 reverse circulation (RC) drill holes (26WCRC018-26WCRC032) indicate broad zones of silver mineralisation both within and west of the recent MRE block model, with silver hosted in intensely silica-altered granite and quartz-carbonate veins within the MMFZ (Figure 2, Figure 3). Most of the new mineralisation defined by the RC drilling lies outside the Elizabeth Hill MRE, increasing the scale of the mineralised system and providing new tonnes and metal for MRE updating in Q4 2026. The strongest results are from holes 26WCRC019 and 26WCRC025, drilled immediately west of the current MRE on cross-section H-H’ (Figure 13) and 26WCRC020 on cross-section I-I' (Figure 14). • Hole 26WCRC019 returned 41m @ 23g/t Ag from 1m (including 26m @ 27g/t Ag from 16m) and ended in mineralisation. • Hole 26WCRC020 was mineralised from surface and returned 44m @ 26g/t Ag (including 31m @ 30g/t Ag from 3m). • Hole 26WCRC025, on the same section and to the west of 26WCRC019 also returned wide mineralised intervals with greater than 10g/t Ag, with the better interval returning 12m @ 15g/t Ag from 31m where the hole ended in mineralisation in this interval. • Other holes, 26WCRC018 and 26WCRC024 (on Sections E-E’ and C-C’, respectively) returned minor intervals of 1m @ 15g/t Ag from 56m and 46m, respectively. Other RC drill holes, despite hitting strong alteration in the MMFZ, did not intersect significant silver mineralisation. Strongly to extremely silicified alteration in granite has been logged across sections B-B’, C-C’, D-D’ and E-E’, interpreted to mark the continuation of the Elizabeth Hill alteration system within the MMFZ (Figure 2, Figure 7, Figure 8, Figure 9, Figure 10). Importantly, high grade lead (Pb) was intersected in 26WCRC018, with 9m @ 5.3% Pb from 55m downhole depth, including 1m @ 17.2% Pb from 56m and 1m @ 16.4% Pb from 62m (Appendix 4). Zones of high-grade lead typically flank high grade silver zones at the Elizabeth Hill deposit and may indicate the presence of silver mineralisation further to the north along the MMFZ. This is supported by shallow, scout aircore hole 25WCAC008 with 0.5m @ 61g/t Ag from 8m. The Company will be undertaking extensive surface geophysical surveys in coming weeks to test this trend to the north towards Maitland (Figure 5). Full cross-section descriptions and figures are provided in Appendix 1. Significant assay results are summarised in Table 3 and Table 4.

ASX: WCE ANNOUNCEMENT 9 July 2026 WEST COAST SILVER LIMITED ASX | WCE Page 10 NEXT STEPS Following the maiden MRE release and encouraging RC drilling results, West Coast Silver will continue to advance Elizabeth Hill through: • Ongoing drilling to expand the scale of the Elizabeth Hill mineralised system through testing of depth extensions, infill lower-density areas within the MRE to improve resource categorisation, and evaluation of along-strike and near-mine extensions, including Maitland and Elizabeth Hill South prospects. • Drill planning underway to follow up on Elizabeth Hill Deeps drilling results. • Detailed geological and structural review of all 2025-2026 drilling data, including interpretation of the change in strike and plunge of silver mineralisation, to plan and prioritise follow-up drilling at Elizabeth Hill North and South, and newly identified targets in the northwest of the project area. • Surface and downhole geophysical surveys for new target generation along the MMFZ and to support further extension and development of Elizabeth Hill during 2026, including surface IP, CSAMT, EM and downhole EM methods. • Economic studies based on an upgraded and potentially larger-scale JORC MRE of near-surface lower grade and deeper higher-grade mineralisation, to support evaluation of a project development pathway. • Regional exploration designed to discover repeats of the Elizabeth Hill Project, including potential drill testing of the Elizabeth Hill South prospect and other priority targets along the MMFZ (Figure 5). ASX: WCE ANNOUNCEMENT 9 July 2026 WEST COAST SILVER LIMITED ASX | WCE Page 11 Figure 5. Elizabeth Hill regional exploration prospects plan view. West Coast Silver is advancing to test beyond Elizabeth Hill multiple exploration prospects and targets that remain under-explored, having indications of elevated Ag, Pb, Zn, Cu and Ni from surface geochemistry, sparse drilling and associated with geophysics defined fault structures. ASX: WCE ANNOUNCEMENT 9 July 2026 WEST COAST SILVER LIMITED ASX | WCE Page 12 About The Elizabeth Hill Project Elizabeth Hill is historically one of Australia’s highest grade silver projects, with a proven production history and significant untapped potential: • Demonstrated high-grade production: 1.2Moz of silver was produced from just 16,830t of ore at a head grade of 2,194g/t (70.5 oz/t Ag)5 , demonstrating the exceptional grade of the deposit. • Previous mining ceased in 2000 due to low silver prices (US$5)6 . The current silver price environment is materially higher than when mining ceased in 2000. • Low-cost processing potential: Historical silver recovery was achieved via gravity separation, a low-cost technique well-suited to the deposit's native silver mineralisation. • Resource growth potential: The deposit remains open at depth and along strike. Consolidation of the surrounding land package into a single contiguous 180km² holding provides additional opportunity to discover further Elizabeth Hill-style deposits. • Strategic location and infrastructure: The project is in the world-class West Pilbara mining jurisdiction with a granted mining lease, and an MOU with Artemis Resources Ltd to evaluate the Radio Hill processing facility as a potential treatment option for Elizabeth Hill material. Through the consolidation of surrounding land packages, a significant portion of the Munni Munni Fault System and subparallel structures are now within WCE’s tenement holding, all considered prospective for Elizabeth Hill- style silver mineralisation.

ASX: WCE ANNOUNCEMENT 9 July 2026 WEST COAST SILVER LIMITED ASX | WCE Page 14 Appendix 1: Cross Sections ASX: WCE ANNOUNCEMENT 9 July 2026 WEST COAST SILVER LIMITED ASX | WCE Page 15 Cross Section B – B’ with RC Drill Holes 26WCRC005 - 26WCRC008 and 26WCRC023 RC drill holes 26WCRC005 to 26WCRC008 (Figure 2, Figure 7), released previously (refer WCE ASX Announcement dated 9 June 2026), on cross section B – B’ intersected a broad envelope of silicified granite within which lies a highly silicified subvertical zone with quartz carbonate veins, the latter is interpreted to represent the core of the broader MMFZ. Some lenses of ultramafic rock are located within the granite. Drill hole 26WCRC005 intersected 7m @ 15g/t Ag from surface, 6m @ 14g/t Ag from 18m and 4m @ 14g/t Ag from 33m. Based on the logging of 26WCRC023, the hole contains a 72m down hole intersection of the altered MMFZ. Figure 7. Cross section B-B’ showing RC holes 26WCRC005 - 26WCRC008 and 26WCRC023 ASX: WCE ANNOUNCEMENT 9 July 2026 WEST COAST SILVER LIMITED ASX | WCE Page 16 Cross Section C – C’ with RC Drill Holes 26WCRC009 - 26WCRC012, 26WCRC022, 26WCRC024 The RC holes (26WCRC009-012, released previously refer WCE ASX Announcement dated 9 June 2026; and 26WCRC022, 26WCRC024), on cross section C – C’ (Figure 2, Figure 8) intersected a complex array of intensely silicified quartz-carbonate veins hosted within granite. A high-grade intersection of 2m at 96g/t Ag from 91m in 26WCRC012 is associated with the lower part of this vein networking within ultramafic rocks. In 26WCRC010, this networking is associated with elevated lead grading up to 1.66% Pb from 55m to 70m down. The same relationship exists in 26WCRC009 with lead up to 2.43% Pb within the interval from 40m to 54m down hole. Anomalous silver exists around the upper margin of the higher-grade lead zone in 26WCRC009 (10.95g/t Ag from 39-40m) and lower margin in 26WCRC010 (8.52g/t Ag from 69-70m). This provides a good example of the general spatial correlation between lead and silver. The other high grade silver intersection on this cross section is 1m at 157g/t Ag from surface in 26WCRC011. Drill hole 26WCRC024 contained 1m @ 15g/t Ag from 46m whereas drill hole 26WCRC022 did not have any significant intersections. It is interpreted from logging that 26WCRC022 was drilled obliquely down the MMFZ, as represented by a 117m zone of variably silicified granite and ultramafic rocks. RC hole 26WCRC024 was designed to test the western extent of the MMFZ and for silver mineralisation interpreted to be hosted in granite to the west of the MMFZ. Based on the logging of 26WCRC024, it is interpreted this hole did not intersect the MMFZ. ASX: WCE ANNOUNCEMENT 9 July 2026 WEST COAST SILVER LIMITED ASX | WCE Page 17 Figure 8. Cross section C-C’ showing RC holes 26WCRC009 - 26WCRC012, 26WCRC022 and 26WCRC024 ASX: WCE ANNOUNCEMENT 9 July 2026 WEST COAST SILVER LIMITED ASX | WCE Page 18 Cross Section D – D’ with RC Drill Holes 26WCRC013 - 26WCRC015 and 26WCRC021 Four RC drill holes (26WCRC013-015, released previously refer WCE ASX Announcement dated 9 June 2026; and 26WCRC 021) were drilled on cross section D – D’ (Figure 2, Figure 9). Assay results were received for all the holes on cross section D-D’ with low levels of silver mineralisation (10.4g/t Ag) intersected in 26WCRC013 from 6m to 7m in partially weathered. RC hole 26WCRC014 did not contain silver mineralisation, however from 46m to 57m it contained a zone of elevated lead mineralisation that graded up to 0.77% Pb within intensely silicified granite. This zone is interpreted to be the core of the MMFZ. Drill hole 26WCRC021 did not contain any significant mineralisation. Figure 9. Cross section D-D’ showing RC holes 26WCRC013 - 26WCRC015 and 26WCRC021 ASX: WCE ANNOUNCEMENT 9 July 2026 WEST COAST SILVER LIMITED ASX | WCE Page 19 Cross Section E – E’ with RC Drill Holes 26WCRC016 - 26WCRC018 and 26WCRC028 Assay results have now been received for all the four RC holes (26WCRC016-017, released previously refer WCE ASX Announcement dated 9 June 2026; and 26WCRC018 and 26WCRC028) drilled on cross section E – E’ (Figure 2, Figure 10). Low levels of silver mineralisation were intersected in 26WCRC017 (17.4g/t Ag from 25-26m) associated with millimetre scale carbonate veins in a 2m thick ultramafic lens. While 26WCRC016 did not contain silver mineralisation, the interval from 42m to 48m did contain elevated lead mineralisation up to 0.44% Pb. An empirical observation from reviewing the RC drilling and assay data is that spatially, lead generally seems to be located outside the zone containing higher silver grades but is still within the overall mineral system. Drill hole 26WCRC018 intersected 1m @ 15g/t Ag from 56m. Drill hole 26WCRC028 did not contain any significant mineralisation. Based on the logging of 26WCRC018, there is a large section of silica and quartz carbonate veining from 54m to 71m down hole. This interval corresponds to a zone of intensely silicified granite, where rock textures have been destroyed by the silica alteration, containing up to 10% visible galena in the RC chips. It is interpreted this large section represents the core of the MMFZ, and an extension of the alteration associated with the Elizabeth Hill mineral system. Figure 10.

The drill holes intersected highly silicified granite, which is interpreted to represent the MMFZ, but did not contain any significant silver mineralisation. Figure 11.

The hole was drilled to test the down dip extension silver (0.5m @ 61g/t Ag from 8m) reported in 25WCAC008 (refer WCE ASX Announcement dated 24 February 2026), as well as the northern extension of the MMFZ and continuation of the alteration and increased lead mineralisation identified in sections E-E’ and F-F’. Although the drill hole intersected highly silicified granite interpreted to represent the extension of the MMFZ, it did not contain any significant silver mineralisation. Figure 12.
