During the quarter, the Company commenced an aggressive drilling program aimed at expanding the footprint of silver mineralisation, identifying new exploration targets and progressing the project toward resource definition and potential resource development studies. Subsequent to the quarter, the Company released its inaugural Mineral Resource Estimate, establishing Elizabeth Hill as a high-grade silver project and providing a clear pathway toward economic evaluation and development studies. Elizabeth Hill Silver Project (Pilbara, Western Australia) • During the quarter, assay results were received from the Phase 2 diamond drilling program completed in late 2025. The results confirmed extensive high-grade silver mineralisation and included: • 27.4m @ 1,314 g/t Ag from 49m (hole 25WCDD014) including multiple bonanza-grade intervals with peak grades up to 33,107 g/t Ag (1,064 oz/t) over 0.35m. • 22m @ 578 g/t Ag from 6m in hole 25WCDD019 demonstrating mineralisation extending northwest of previous drilling. • Additional high-grade intercepts including 1.95m @ 1,252 g/t Ag in hole 25WCDD022. • These results confirm the potential for a laterally extensive high-grade silver system at Elizabeth Hill and validate historical production grades. • A Reverse Circulation (“RC”) drilling program of up to ~4,000m commenced during the quarter targeting extensions to the high-grade silver mineralisation at Elizabeth Hill: • Initial drilling is focused on northern and southern extensions of the mineralised system along the Munni Munni Fault. • Drilling targets shallow mineralisation within ~150m of surface, supporting potential for open-pit, low-cost resource growth. • Program designed to expand the mineralised footprint and support delivery of a maiden Mineral Resource Estimate. • A late 2025 high-resolution drone magnetic survey covering approximately 14 km² was interpreted to better define structural controls on mineralisation. Key outcomes include: • 28 structural targets identified at interpreted fault intersections. • Eight targets located within 1.2 km of the historical Elizabeth Hill mine. • The Munni Munni Fault confirmed as a key mineralised structure over ~6.8 km strike. • Additional targets identified along the eastern margin of the Munni Munni intrusion. Highlights ASX: WCE ANNOUNCEMENT 29 April 2026 2 ASX | WCE WEST COAST SILVER LIMITED westcoastsilver.com.au Mineral Resource Estimate (MRE) • Subsequent to quarter end, the Company announced an inaugural silver Mineral Resource Estimate (MRE) for the Elizabeth Hill Silver Project comprising 141kt at 617 g/t Ag for 2.79Moz of contained silver. The MRE establishes a high-grade foundation for the Project and confirms mineralisation remains open along strike and at depth. A Whittle open pit optimisation supports reasonable prospects for eventual economic extraction, with the optimised pit capturing the majority of the current mineralisation. The Company will continue drilling and geophysical programs aimed at expanding the resource base and advancing the Project toward development studies. Figure 1, shows the areas of drilling (underway) to expand the existing MRE. Refer labels “2026 EH North RC Test Area” (purple) and “2026 EH Deeps DD Test Area” (blue). Figure 1. Elizabeth Hill April 2026 MRE optimized open pit slice in long-section view. Majority of drilled and mined mineralisation is captured within the constraining Inferred and Indicated resource pit shell. Areas of planned and in- progress 2026 exploration drilling to expand the April 2026 MRE and optimized pit are included on long-section. • Subsequent to quarter end, the Company commenced a diamond drilling program of up to 1,500m targeting down-dip and down-plunge extensions of high-grade silver mineralisation beneath the historical Elizabeth Hill mine. This program represents the first systematic test of the Company’s structural model along the Munni Munni Fault and is aimed at confirming continuity and scale at depth and may materially expand the Elizabeth Hill mineralised system. Drilling is expected to take approximately four to six weeks, with assay results anticipated progressively during Q2 2026. • Subsequent to quarter end, the Company identified a new high-priority drill target at Elizabeth Hill following the application of Down Hole Electromagnetics (DHEM), which defined a discrete, untested conductive plate adjacent to the historical mine. The anomaly exhibits conductance ASX: WCE ANNOUNCEMENT 29 April 2026 3 ASX | WCE WEST COAST SILVER LIMITED westcoastsilver.com.au values consistent with potential mineralisation and is supported by favourable structural positioning and nearby historical intercepts. A diamond drill hole is being advanced to test this target, representing a compelling near-mine opportunity with potential to expand the Elizabeth Hill mineralised system.

Other Projects & JV activity • Falcon Metals (JV, E09/2457): Subject to the undertaking of a Heritage survey Falcon Minerals Ltd (ASX: FAL) plans to commence a maiden RC drilling program across the Olsen Well gold anomaly (a 5.8 km long-soil anomaly). • Portfolio focus: Due to the focus on Elizabeth Hill drilling priorities, no field activities were completed at other projects during the Quarter. West Coast Silver is pleased to present the Company’s quarterly activities report for the quarter ending 31 March 2026 (“the Quarter”). During the Third Quarter (January – March 2026): The primary focus of the Company’sactivities during thequarter was exploration at the Elizabeth Hill Silver Project, where West Coast Silver continued to advance exploration and target generation following the highly encouraging results from the 2025 diamond drilling campaign. During the period the Company released bonanza-grade silver assay results, completed detailed geophysical surveys which identified multiple new exploration targets, and commenced an RC drilling program of up to 4,000m designed to expand the footprint of high-grade silver mineralisation at Elizabeth Hill. West Coast Silver owns 70% of the historical Elizabeth Hill Silver Project (“Project”or “Elizabeth Hill”), 70% of the silver rights across six tenements forming the Pinderi Hills Project, and 70% ownership of three additional tenements and one tenement application surrounding the Elizabeth Hill project area. This consolidated landholding totals approximately 180 km² and is located in the Tier-1 Pilbara mining region of Western Australia, providing significant exploration upside along the Munni Munni structural corridor, which hosts the Elizabeth Hill deposit. Commenting on the quarter, Executive Chairman Bruce Garlick said: “West Coast Silver has delivered another highly productive quarter at Elizabeth Hill, highlighted by the release of exceptional high-grade silver drill results and the identification of multiple new exploration targets through detailed geophysical surveys. The results continue to demonstrate that Elizabeth Hill represents part of a much larger mineralised system.” ASX: WCE ANNOUNCEMENT 29 April 2026 4 ASX | WCE WEST COAST SILVER LIMITED westcoastsilver.com.au “The commencement of our RC drilling program marks the next step in systematically expanding the footprint of high-grade silver mineralisation around the historic mine and testing priority targets along the Munni Munni Fault corridor. With all targets located close to surface, success has the potential to deliver rapid resource growth.” “With a strengthened balance sheet and an expanded technical team, including ERM consulting and Serge Smolonogov as Technical Director, the Company is well positioned to accelerate exploration across Elizabeth Hill and to continue growth beyond the current maiden Elizabeth Hill Mineral Resource Estimate. The work completed this quarter reinforces our belief thatElizabeth Hill has the potentialtoemerge as one ofAustralia’s mostsignificant high-grade silver discoveries, where by virtue of unique high grades, there is exceptional metal content in a smaller host rock volume. This translates to fewer tonnes to be mined for a lower cost of mining and processing.” Figure 2. Visible native silver has been qualitatively observed and assayed in drill hole 25WCDD014 from 74.60m to 75.20m in calcite-quartz vein (photo shown). Note: 50,000g/t or 5% silver over 10cm. Reported down-hole intervals may not represent true width. Refer to West Coast Silver ASX announcement dated 4 February 2026 for further information.1 • Phase 2 diamond drilling was completed comprising 13 holes for 1,015m, confirming extensive high- grade silver mineralisation at the Elizabeth Hill Project. • Significant intersections included: » 27.4m @ 1,314 g/t Ag from 49m in hole 25WCDD014, including a bonanza-grade interval of 33,107g/t Ag over 0.35m. » 22m @ 578 g/t Ag from 6m in hole 25WCDD019, including 0.9m @ 9,070 g/t Ag. » 25.8m @ 151 g/t Ag from 20m in hole 25WCDD020. » 1.95m @ 1,252 g/t Ag from 54.6m in hole 25WCDD022, including 1.2m @ 1,894 g/t Ag. • Drilling confirmed high-grade silver mineralisation close to surface and above historical mine workings, indicating the system remains open and may extend beyond the historic mine footprint. • 76-hole aircore drilling program (1,060m) completed targeting near-mine prospects, intersecting alteration and structural features consistent with the Elizabeth Hill mineralised system. 1 Refer ASX Announcement “Bonanza Silver Hits at Elizabeth Hill” dated 4 February 2026 Elizabeth Hill Silver Project Highlights ASX: WCE ANNOUNCEMENT 29 April 2026 5 ASX | WCE WEST COAST SILVER LIMITED westcoastsilver.com.au • An RC drilling program of up to 4,000m commenced to test extensions of high-grade mineralisation and support a maiden Mineral Resource Estimate. • High-resolution drone magnetic survey (~14 km²) identified multiple structural targets along the Munni Munni Fault, highlighting potential for additional mineralisation along the corridor. Phase 2 Drill Results During the quarter, West Coast Silver reported assay results from its Phase 2 diamond drilling program comprising 13 holes for 1,015m, designed to test near-surface mineralisation and down-plunge extensions beneath the historical Elizabeth Hill mine workings (Figure 3). Drilling confirmed high-grade silver mineralisation in multiple holes, with the standout result from hole 25WCDD014 returning 27.4m @ 1,314 g/t Ag from 49m, including bonanza-grade intervals up to 33,107 g/t Ag. Additional significant intersections included 22.0m @ 578 g/t Ag (25WCDD019) and 1.95m @ 1,252 g/t Ag (25WCDD022). Overall, 9 of the 13 drill holes intersected silver mineralisation, confirming the continuity of the Elizabeth Hill silver system and its potential for further expansion. Figure 3.

ASX: WCE ANNOUNCEMENT 29 April 2026 6 ASX | WCE WEST COAST SILVER LIMITED westcoastsilver.com.au 2026 RC Drilling Program An RC drilling program of up to 4,000m has commenced to test extensions of high-grade silver mineralisation north and south of the historic mine and support a maiden Mineral Resource Estimate targeted for Q3/Q4 2026. The RC drilling program is designed to test extensions of mineralisation along strike, as well as up-dip and down- plunge of the historical Elizabeth Hill underground mine. Drilling is targeting areas identified from 2025 diamond and aircore programs, including Elizabeth Hill North and South, where previous work intersected near-surface silver mineralisation. Drilling is expected to take approximately four to six weeks, with assay results anticipated progressively during Q2 2026. All drill holes are designed to intersect the Munni Munni Fault, a key structural control on mineralisation, reinforcing the scale potential of the Elizabeth Hill system. Subsequent to quarter end, a diamond drilling program of up to ~1,500m has commenced targeting down-dip and down-plunge extensions beneath the Elizabeth Hill mine, with planned holes shown in Figure 1 on page 2 (light blue), complementing the current RC program (purple). Aircore (AC) Drill Program During the quarter, West Coast Silver completed a 76-hole aircore (“AC”) drilling program for 1,060m targeting near-mine and regional extensions of the Elizabeth Hill mineralised system. The drilling confirmed shallow silver mineralisation from surface and demonstrated clear strike extensions of the system both north and south of the Elizabeth Hill mine. At Elizabeth Hill North, mineralisation extends approximately 290m along strike from the historical workings, with multiple shallow intercepts confirming strong continuity along the Munni Munni Fault corridor. At Elizabeth Hill South, mineralisation was confirmed approximately 300m south of the mine, highlighting the potential for a significant southern extension of the system (Refer Figure 4). Aircore drilling also intersected alteration and lithologies consistent with the Elizabeth Hill mineralised setting, including chlorite–silica alteration, carbonate veining and iron oxide staining associated with interpreted structures. These results reinforce the interpretation that Elizabeth Hill forms part of a broader mineralised system with potential for rapid resource growth along strike. Mineralisation interpreted to be associated with ultramafic rocks is locally hosted within granite to the north of Elizabeth Hill, highlighting new exploration areas. Following the success of the aircore drilling program, the Company has commenced a follow-up RC drilling campaign of up to 4,000m to test beneath the aircore holes and target near-surface extensions of the Elizabeth Hill mineralised system. The program is designed to expand the footprint of high-grade mineralisation and support the progression toward a maiden Mineral Resource Estimate. ASX: WCE ANNOUNCEMENT 29 April 2026 7 ASX | WCE WEST COAST SILVER LIMITED westcoastsilver.com.au Figure 4. Location of 2025 aircore drill holes Geophysics and Target Generation During the quarter, the Company initiated a trial geophysical program over a small area of the Elizabeth Hill mine designed to identify extensions to high-grade silver mineralisation and refine structural controls. The program incorporates both borehole and surface-based techniques, including: • Downhole Electromagnetic (DHEM) and Borehole Magnetometric Resistivity (BHMMR) surveys targeting depth extensions below and south of the historic Elizabeth Hill mine • Ground Fixed Loop Electromagnetic (FLEM) and Induced Polarisation (IP) over the mineralised footprint These techniques are designed to detect conductive and resistive/chargeable bodies potentially associated with sulphide and native silver mineralisation and to identify potential extensions to known mineralised zones. The DHEM program utilises completed 2025 diamond drill holes to test mineralisation beyond current drilling and to calibrate geophysical responses against known mineralisation, enabling improved targeting across the broader tenement package. ASX: WCE ANNOUNCEMENT 29 April 2026 8 ASX | WCE WEST COAST SILVER LIMITED westcoastsilver.com.au Southern Geoscience Consultants have been engaged to undertake the geophysical program. In addition, the Company completed a high-resolution drone magnetic survey (~14 km²), which identified multiple structural targets along the Munni Munni Fault, further supporting the interpretation of a broader mineralised system. The integration of drilling, geophysics and structural modelling is expected to materially enhance targeting efficiency and support rapid resource growth along the Munni Munni corridor. Figure 5. Drone magnetics (total magnetic intensity reduced to the pole) of the Elizabeth Hill area. The Munni Munni Fault (host to silver at the Elizabeth Hill Mine) and secondary structures are apparent in the data, with 18 structural targets (fault bends and intersecting structures) are interpreted in the survey area with targets within 7-8 km of the Elizabeth Hill Mine ASX: WCE ANNOUNCEMENT 29 April 2026 9 ASX | WCE WEST COAST SILVER LIMITED westcoastsilver.com.au Technical Review During the quarter the Company undertook a technical review and site visit at Elizabeth Hill with ERM and specialist consultants to integrate drilling, geological and geophysical datasets and refine the exploration strategy. The review focused on: • Refining priority drill targets • Advancing the geological and structural model • Identifying opportunities for resource growth • Supporting future development studies Outcomes from the review will underpin the Company’s 2026 exploration and development strategy, including systematic drilling and progression toward a JORC Mineral Resource Estimate. Inaugural Elizabeth Hill Mineral Resource Estimate Work was commenced in February by ERM Consultants on an inaugural Elizabeth Hill Mineral Resource Estimate (MRE). The work included all historical exploration, grade control, mining and most recent 2025 / 2026 drilling outcomes. Work included a full review of underground production and accuracy of surveyed workings and stopes to ensureaccurate orebody depletion estimates. Thereported Inferred and Indicated resources exclude previously mined ore and are reported above a 20 g/t Ag cut-off grade. The Elizabeth Hill April 2026 MRE outcomes follow. When compared to the previous 2011 East Coast Minerals NL MRE completed at the same cut-off grade as the 2026 MRE, there is significant growth between the JORC 2004 and the JORC 2012 variants of the resource. There has been significant growth through addition of additional drilling and inclusion of more accurate reconciled underground workings allowing remnant ore to be more accurately captured in the estimate. The 2011 MRE to JORC 2004 standards is presented below. The variance between 2026 and 2011 is presented below with gains across reported tonnes, grade and silver ounces. 1 In August 2011, P Jones from AM Maynard & Associates completed a Mineral Resource estimate which was reported in accordance with the 2004 Edition of the JORC Code. The Mineral Resource was confined to a conceptual pit design approximately 15–30 m above the presumed location of the underground workings. According to the report “the extent of underground workings is only sketchy since at least some of the survey data has been lost and only fragmentary data remains”, (East Coast Minerals NL, 2011 p3). 2 Refer ASX Announcement WCE “Elizabeth Hill Silver Project – 2.8 Moz Silver Mineral Resource Estimate” dated 22 April 2026 compliant with JORC (2012). ASX: WCE ANNOUNCEMENT 29 April 2026 10 ASX | WCE WEST COAST SILVER LIMITED westcoastsilver.com.au The inaugural MRE establishes Elizabeth Hill as an exceptionally high-grade silver system, where comparatively low tonnes contain higher than industry norm metal content. The strategic importance lies in grade concentration, value density, economic robustness, and growth optionality. The MRE delivers: • An inaugural publicly disclosed JORC-compliant MRE as a foundation to future growth. • Grades that are exceptional by global peer standards. • A clearly defined risk–reward profile driven by resource classification and expansion potential. • Validation of open-pit economic potential well below current silver prices. • Strong credibility from historical production performance and close reconciliation against areas mined. Figure 6: Elizabeth Hill MRE optimized pit design with trace of Munni Munni Faultand mineralised corridor within the pitextents. 2025 and 2026 exploration drill hole collars are included as reference to areas of future extension. Assay results from 2026 exploration drilling are expected in May 2026. ASX: WCE ANNOUNCEMENT 29 April 2026 11 ASX | WCE WEST COAST SILVER LIMITED westcoastsilver.com.au Figure 7: Elizabeth Hill April 2026 MRE optimized open pit slice in long-section view. Majority of drilled and mined mineralisation is captured within the constraining Inferred and Indicated resource pit shell. Areas of planned and in-progress 2026 exploration drilling to expand the April 2026 MRE and optimized pit are included on long-section. The mineral resource classification split is: • Indicated: 369 Koz (14%) • Inferred: 2.42 Moz (86%) The majority of mineralisation is within the Inferred resource category. To be able to be converted to Probable reserve the Inferred resource will require tighter infill drilling to achieve an Indicated resource level of confidence. The upside of infill drilling a high-grade deposit such as Elizabeth Hill is that there is strong likelihood of additional higher-grade, short-range structures not intersected by broader spaced drilling being added to mineral inventory. The April 2026 Elizabeth Hill MRE with optimized pit shell highlights that any mineralisation defined by 2026 planned near-mine exploration drilling to the north and below the optimized pit shell will be new silver ounces outside of the current MRE and would be included as new additional mineralisation in an end of year MRE update. ASX: WCE ANNOUNCEMENT 29 April 2026 12 ASX | WCE WEST COAST SILVER LIMITED westcoastsilver.com.au 2026 Outlook West Coast Silver has outlined a clear pathway to resource growth and development at the Elizabeth Hill Silver Project, with a major drilling and exploration campaign planned throughout 2026. Key activities include: • RC drilling program: An RC drilling program of up to ~4,000m is underway at Elizabeth Hill targeting near- surface extensions of mineralisationidentified by theaircoredrilling program along the Munni Munni Fault corridor. This follow-up drill program is expected to take approximately four to six weeks, with assay results anticipated progressively during Q2 2026. • Geophysics: Multi-method geophysical programs (DHEM, BHMMR, FLEM and IP) underway to refine drill targeting and identify extensions to mineralisation both near-mine and regionally. • Deeper drilling: A diamond drilling program targeting deeper extensions of the Elizabeth Hill mineral system (“EH Deeps”) is planned following receipt of RC drilling results. • Resource definition: Subsequent to quarter end, the Company announced an inaugural MRE for Elizabeth Hill of 141kt at 617 g/t Ag for 2.8Moz, confirming a high-grade system with potential for further growth. Drilling results will support the delivery of an expanded Mineral Resource Estimate in late 2026. • Development studies: Progress toward a scoping study will evaluate potential development pathways for the Elizabeth Hill project. These activities form part of a major drilling campaign planned across 2026, aimed at expanding the footprint of high-grade mineralisation and advancing Elizabeth Hill toward resource definition and potential development studies. ASX: WCE ANNOUNCEMENT 29 April 2026 13 ASX | WCE WEST COAST SILVER LIMITED westcoastsilver.com.au About the Elizabeth Hill Project Elizabeth Hill is one of Australia’s high-grade silver projects and has a proven production history outlined below: • High grades enabled low processing tonnes: 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)2 . • Previous mining operation ceased in 2000: because of low silver prices (US$5/oz)3 • Simplistic historical processing technique: native silver was recovered via low-cost gravity separation techniques. • Untapped potential remains in ground with deposit open at depth and recent consolidation of land package offers potential to discover more Elizabeth Hill style deposits. • Tier 1 Mining Jurisdiction located on a mining lease with potential processing option at the nearby Radio Hill site. Figure 8. Location of Project Combined Tenements Through the consolidation of the surrounding land packages into a single contiguous 180 km2 package significant exploration and growth potential exists both near mine and regionally. The land package holds a significant portion of the Munni Munni fault system which is considered prospective for Elizabeth Hill look-a-like silver deposits. 2 WAMEX Annual Report,1 April 2014 to 31 March 2015, Elizabeth Hill Silver Project, Global Strategic Metals NL, p16. 3 www.kitco.com/charts/silver ASX: WCE ANNOUNCEMENT 29 April 2026 14 ASX | WCE WEST COAST SILVER LIMITED westcoastsilver.com.au • Due to the focus on the drilling of the Elizabeth Hill Silver Project no field activities were undertaken on the Company’s other exploration projects during the quarter. • Subject to the undertaking of a Heritage survey Falcon Minerals Ltd (ASX: FAL) plans to commence a maiden RC drilling at the Olsen Well gold anomaly (a 5.8 km long-soil anomaly). The Errabiddy project comprises 3 tenements with a combined area of approximately 545 km2 and which are considered prospective for Ni, Cu, Au, REE’s, Li and graphite. The results from routine reconnaissance prospecting, soil sampling and rock chip sampling which was previously undertaken on the project by West Coast Silver has resulted in an initial focus on graphite and gold. Falcon Metals Joint Venture Previously, West Coast Silver entered an Earn-in, Joint Venture and Mineral Rights Agreement with Falcon Metals Ltd (ASX: FAL) (“Falcon”), granting Falcon the right to earn up to a 70% interest in Exploration Licence E09/2457 by spending $2 million in two stages over a 60-month period, covering all minerals excluding graphite. The Errabiddy Gold Project is a craton margin gold target, located 220 km northwest of Meekatharra in Western Australia. The 519 km2 JV licence covers a 42 km strike extent of the Errabiddy Shear Zone, which is considered highly prospective, remains underexplored and with no drilling for gold conducted within the project tenure. The Errabiddy Shear Zone is a compelling cratonic margin gold target which contains known gold mineralisation. Cratonic margins are considered prospective for the formation of large gold deposits, including the Tropicana deposit that was discovered on the eastern margin of the Yilgarn Craton in 2005 through the follow up of a regional public domain gold-in-soil anomaly. West Coast Silver initially identified Olsen Well as a target from a review of public domain Bulk Leach Extractable Gold (“BLEG”) stream sediment data that highlighted this area. Additionally, regional geochemical sampling by the Geological Survey of Western Australia, with a 4 km spaced geochemical grid, detected a 6 ppb Au anomaly near Olsen Well. The sampling undertaken by West Coast Silver in 2023 revealed the Olsen Well Prospect to be a significant gold in soil anomaly with a surface extent of at least 3 km x 1 km with a peak soil value of 234 ppb Au. The soil sampling grid was 300m x 100m with 462 samples collected, and the anomaly coincident with quartz and iron rich rocks hosted within a granitic terrain. This anomalous gold in soil footprint was expanded to a strike of 5.8 km by subsequent soil sampling by JV partner Falcon Metalsi . The Olsen Well gold target is considered by Falcon Metals to be analogous to Benz Mining’s (ASX:BNZ) Glenburgh deposit (16.3Mt @ 1.0g/t for 510,000 ounces of gold4 ) also discovered from regional stream sampling followed by soil sampling in gneissic terrain along the northwest margin of the Yilgarn craton. RC drilling of the 3 km to 5.8 km, >10 ppb gold in soil anomaly at Olsen Well by the company’s JV partner Falcon Metals (ASX:FAL) is due to commence following Heritage clearance likely in early 2026. This would be the first ever drilling program at Olsen Well. 4 Refer to Benz Mining ASX Announcement: “Benz to Acquire WA Gold Projects from Spartan Resources” dated 6 November 2024 Other Projects Errabiddy Falcon JV ASX: WCE ANNOUNCEMENT 29 April 2026 15 ASX | WCE WEST COAST SILVER LIMITED westcoastsilver.com.au Lithium Potential There has been no exploration undertaken on the Andover South tenement E47/4352 during the quarter.
