Announcement PDF ASX:WCE ANNOUNCEMENT 16th July 2025 High Grade Silver Intercepts Near Surface at Elizabeth Hill Highlights • Assays from drill hole 25WCDD001, the first drill hole completed from the 2025 program has returned a significant high-grade silver zone: • 21 metres at 1,047g/t Ag from 10 metres including. • 8 metres at 2,632 g/t Ag from 22 metres including • A spectacular interval of 1 metre at 15,071 g/t Ag from 27 metres. • Impressive near surface results from drill hole 25WWCDD002 include: • 15 metres at 723g/t Ag from 1 metre including: • 3 metres at 2,639g/t Ag from 1 metre. • Gold (Au) reported in laboratory assays with peak assay from drill hole 25WWCDD002 returning: • 1metre at 2.03g/t Au from 4 metres. • To date, only assay results for holes 25WCDD001 & 25WCDD002, have been received from the laboratory. However, the new intersections of near-surface high grade silver provide impetus for further evaluation and quantification of potential economic shallow silver mineralization. • Review of historical drilling data provides additional indication of economic near surface mineralisation • The additional 8 drill holes have been dispatched to the laboratory for assay with assay results expected progressively over a 6–8 week period. • Whilst the drilling component of the program has been completed, logging of holes 11 & 12 continues, and samples will be dispatched to the laboratory once ready WEST COAST SILVER LIMITED ASX | WCE ACN: 155 472 834 REGISTERED OFFICE Level 2, 10 Ord Street West Perth, WA 6005 PO Box 1227, West Perth WA 6872, Australia info@westcoastsilver.com.au +61 8 9322 3383 westcoastsilver.com.au ASX:WCE ANNOUNCEMENT 16th July 2025 West Coast Silver Limited (ASX: WCE) (‘West Coast Silver’ or the ‘Company’) is pleased to advise that its inaugural diamond drill program (12 holes for 1,183m) at the high-grade Elizabeth Hill Silver Project in the Pilbara has been completed and has delivered an exceptional results, with shallow, highgrade silver assays returned from the first two drill holes, 25WCDD001 and 25WCDD002. (Figure 1, Figure 2 and Figure 3); Both holes intersected mineralisation from near surface, with particularly impressive results from hole 25WCDD001 which intersected: • 21 metres at 1,047g/t from 10 metres including o 8 metres at 2,632 g/t from 22 metres including,  A Spectacular interval of 1 metre at 15,071 g/t from 27 metres. Hole 25WCDD002 intersected • 15 metres at 729g/t from 1 metre including: o 3 metres at 2,639g/t from 1 metre. Drill hole 25WCDD001 was designed to twin historic Alien Metals RC drill hole 22AMC001 which intersected: • 21 metres at 730g/t Ag from 12 metres. WCE diamond drill hole 25WCDD001 and historical RC drill hole 22AMC001 intersected comparable mineralisation, both in width and grade. Slight variations in the grade between the two drill holes may reflect a nuggety nature of silver mineralisation. The drill holes intersected weathered granite to the end of hole proximal to the ultramafic rock/granite contact. 21 Ag (g/t) 1,047 Ag (Troy oz/t) 35.66 8 2,632 84.65 22 25WCDD001 1 15,071 484.56 27 25WCDD002 15 723 23.45 1 3 2,639 84.87 1 Hole ID Interval (m) 25WCDD001 From (m) 10 Including 25WCDD001 and including 25WCDD002 Table.7.–.Significant.Intercept.Table.of.the.first.two.drill.holes.of.West.Coast.Silver.drilling Commenting on the results, Executive Chairman Bruce Garlick said: “We are extremely pleased with this exceptional start to our maiden drill program. To intersect highgrade silver from close to surface in our first two holes is a tremendous result and validates our belief in the near-surface potential at Elizabeth Hill. The grades seen in 25WCDD001 are particularly encouraging and includes a 1meter intercept of nearly 485 ounces per tonne which is further confirmation of the historical grades reported from the deposit.” WEST COAST SILVER LIMITED ASX | WCE Page 2 ASX:WCE ANNOUNCEMENT 16th July 2025 “It is also great to see as part of our historical review that there is a large number of shallow intercepts close to these holes which indicates the potential for quantification of a near surface economic mineralisation.” Figure.7.–.Plan.view.of.868❶.West.Coast.Silver.Diamond.core.drilling.and.historical.drilling WEST COAST SILVER LIMITED ASX | WCE Page 3 ASX:WCE ANNOUNCEMENT 16th July 2025 Figure.8.–.Cross.section.showing.drill.hole.8❶WCDD667.(West.Coast.Silver).with.historical.drill.results¡ WEST COAST SILVER LIMITED ASX | WCE Page 4 ASX:WCE ANNOUNCEMENT 16th July 2025 Figure.9.–.Cross.section.showing.drill.hole.8❶WCDD668.(West..Coast.Silver).and.with.historical.drill.results¡ Near surface mineralisation historical assessment The 2025 West Coast Silver diamond drilling (12 holes) was partly designed to target oxidised, shallow (<50m vertical depth) silver mineralisation north of the underground workings (Figure 1to Figure 7), as reported in historical WAMEX reports and compiled in an Alien Metals data base. Appendices C and D provide drill hole collar details and significant silver intercepts for all historical surface drill holes. Best results in the historical surface drilling (Figure 1) are listed in Table 2. These high grade intersections are located along the interpreted Munni Munni Fault at the contact of the ultramafic/mafic rocks to the east and the granites to the west. This mineralisation extends WEST COAST SILVER LIMITED ASX | WCE Page 5 ASX:WCE ANNOUNCEMENT 16th July 2025 approximately 40m to the north of the projected underground workings. Drill hole EC092 (Figure 1), proximal to the interpreted Munni Munni Fault in the northernmost drill line intersected 1m at 204g/t Ag from 1 metre indicating the shallow, oxide silver mineralisation is still not closed off to the north. The shallow high-grade nature of these silver results gives the Company confidence in the near surface potential of Elizabeth Hill. As a matter of priority, the Company engaged ERM Consultants to carry out a comprehensive analysis of all historical drilling at Elizabeth Hill with a future view to developing workflows that may result in quantifying the near surface silver mineralisation at Elizabeth Hill in line with JORC 2012. Significant silver assays identified from historical drilling include the following: Hole ID Interval (m) 21EHDD003 3.7 Ag (g/t) 6,953 21EHDD003 5.7 6,503 19 21EHDD001 15 1,487 2 22AMC001 21 730 12 AMEHRC009 4 3,788 27 EC092 1 204 1 From (m) 13 Table.8.‗.Significant.Intercepts.in.historical.drilling.(see.Figure.7) Anomalous Gold, Lead, Zinc and Copper assay values returned from the drilling programme will also be further assessed.

WEST COAST SILVER LIMITED ASX | WCE Page 10 ASX:WCE ANNOUNCEMENT 16th July 2025 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) 1 • Previous mining operation ceased in 2000: because of low silver prices (US$5) 2 • 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.❹.‗.Tenement.Location Through the consolidation of the surrounding land packages into a single contiguous 180km2 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. 1 WAMEX Annual Report,1 April 2014 to 31 March 2015, Elizabeth Hill Silver Project, Global Strategic Metals NL, p16 2 www.kitco.com/charts/silver WEST COAST SILVER LIMITED ASX | WCE Page 11 ASX:WCE ANNOUNCEMENT 16th July 2025 This ASX announcement has been authorised for release by the Board of Directors of West Coast Silver Limited.
