Announcement PDF ASX:WCE ANNOUNCEMENT 24th September 2025 Phase 2 Drilling Contract Awarded at Elizabeth Hill Following High-Grade Silver Intercepts Highlights • Phase 2 drilling contract awarded to Wallis Drilling (~1,000m diamond, 2,000– 3,000m air core). • Drilling will consist of a combination of diamond and air core drilling with multiple objectives targeted • Program to test near-surface mineralisation, potential depth extensions and step-out targets1 • WCE’s integrated geological team including ERM consultants is currently finalising defined drill targets which will further refine the drill program • Imminent TEM2 and magnetic surveys to feed into the targeting process • Drilling will commence in ~4-6 weeks • Assays from drill hole 25WCDD008 have identified further high-grade silver mineralisation zones including: • 6 metres at 316g/t Ag from 44 metres; including • 1.4 metres at 1,007g/t Ag from 45 metres • 21 metres at 50g/t Ag from 20 metres • 25WCDD010 has also intersected high-grade silver mineralisation including: • 3.4 metres at 219g/t Ag from 63 metres • Low grade silver mineralisation has also been intercepted in 25WCDD005 at both 165m and 171m on structures associated with the Munni Munni Fault • These intervals demonstrate mineralisation is hosted in subsidiary structures related to the main Elizabeth Hill mineralisation event. These intercepts are well below the historical workings which was suspended at the 102m level in 2000 due to declining silver prices 1 Refer to ASX Announcement dated 5th August 2025 2 Time Domain Electromagnetic 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 24th September 2025 West Coast Silver Limited (ASX: WCE) (‘West Coast Silver’ or the ‘Company’) is pleased to advise that it has awarded its phase 2 expanded drill program to Wallis Drilling. The drill program will consist of a combination of diamond and air core drilling with multiple objectives targeted including quantification of near surface mineralisation at Elizabeth Hill, testing of proven depth extensions and step out drilling to test high priority near mine targets. WCE’s integrated geological team including ERM consultants is currently finalising defined drill targets which will further refine the drill program. Drilling will commence in ~4-6 weeks and will consist of ~1000 m of diamond drilling and 2000-3000m of air core drilling. Commenting, Executive Chairman Bruce Garlick said: “This follow-up drilling program is designed to build on recent high-grade results at Elizabeth Hill, including historic silver intercepts below the workings. We are eager to return to the field within weeks to test multiple growth opportunities including the priority prospective near mine targets aimed at advancing the project.” The Company has received further high-grade silver intercepts from the inaugural diamond drill program (12 holes for 1,183m) at the high-grade Elizabeth Hill Silver Project in the Pilbara. The Company has received the remainder of assay results for six drill holes (25WCDD005, 25WCDD006, 25WCDD007, 25WCDD008, 25WCDD009 and 25WCDD010) for the inaugural drilling program. From the six drill holes, further high-grade silver results were returned for 25WCDD008 and 25WCDD010 (Figure 1 and Figure 2). Both holes intersected silver mineralisation from near surface (Table 2), with particularly impressive results from hole 25WCDD008 including: • 6 metres at 316g/t Ag from 44 metres o • with 1.4 metres at 1,007g/t Ag from 45 metres 21 metres at 50g/t Ag from 20 metres Hole 25WWCDD010 intersected: • 3.4 metres at 219g/t Ag from 63 metres This builds on the outstanding previously announced (West Coast Silver ASX Releases dated 16 July 2025 and 22 August 2025) near surface results including 25WCDD001 which intersected: • 21 metres at 1,047g/t from 10 metres including o 8 metres at 2,632/t from 22 metres including a spectacular interval of 1 metre at 15,071g/t from 27 metres. Drill hole 25WCDD002 intersected: • 15 metres at 723g/t from 1 metre including: o 3 metres at 2,639g/t from 1 metre. Drill hole 25WCDD011 which intersected: • 17 metres at 858g/t Ag from 5 metres including: o 2 metres at 6,349g/t Ag from 7 metres; WEST COAST SILVER LIMITED ASX | WCE Page 2 ASX:WCE ANNOUNCEMENT 24th September 2025 • 10 metres at 850g/t Ag from 47 metres and • 13 metres at 1,615g/t Ag from 62 metres o including 2 metres at 10,049g/t Ag from 63 metres and Drill hole 25WCDD012 also returned significant high-grade silver intercepts including: • 6 metres at 317g/t Ag from 10 metres including: o • 1m at 1,455g/t Ag from 13 metres; and 14 metres at 162g/t Ag from 18 metres. Drill hole 25WCDD007 was completed as a scissor test to validate the near surface oxide mineralisation intersected in historical drill hole, EC085, that contained 18 metres at 581g/t Ag from 12 metres (West Coast Silver ASX Release dated 16 July 2025). While recent drill hole 25WCDD007 intersected 12 metres at 42g/t Ag from 15 metres and 1 metre at 121g/t Ag from 30 metres (Table 1), it confirmed the thickness but highlighted the nuggety grade distribution of the silver mineralisation in the oxide zone. Drill hole 25WCDD009 was designed to test the down plunge extent of the near surface, oxide mineralisation between 25-30m vertically above the historical workings and intersected 4 metres at 66g/t Ag from 45 metres in the interpreted position of the Munni Munni Fault. Drill holes 25WCDD005 and 25WCDD006 intersected minor silver intervals above a 25g/t Ag cut-oƯ (Table 1) despite still intersecting structures containing quartz-carbonate breccias and veins below the historical Elizabeth Hill mine workings. This provides further support to the Company’s interpretation that silver mineralisation plunges to the south within the Munni Munni Fault.

The Company continues to work with ERM to carry out a comprehensive analysis of all historical drilling at Elizabeth Hill with a view to assess the extent of near surface mineralisation at Elizabeth Hill. This process will include any QA/QC checks required to ensure all historical data is of suƯicient quality to be reported from a JORC 2012 perspective. Inaugural Drilling Update Twelve diamond holes have been completed at Elizabeth Hill totalling 1,183 m of drilling. Laboratory assay results have been received for the 12 diamond holes with the final six holes reported in this release. WEST COAST SILVER LIMITED ASX | WCE Page 6 ASX:WCE ANNOUNCEMENT 24th September 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)3. • Previous mining operation ceased in 2000: because of low silver prices (US$5)4. • 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 oƯers 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 3 - 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, and other fault systems subparallel to the Munni Munni fault system, which are considered prospective for Elizabeth Hill look-a-like silver deposits. 3 WAMEX Annual Report,1 April 2014 to 31 March 2015, Elizabeth Hill Silver Project, Global Strategic Metals NL, p16 4 www.kitco.com/charts/silver WEST COAST SILVER LIMITED ASX | WCE Page 7 ASX:WCE ANNOUNCEMENT 24th September 2025 This ASX announcement has been authorised for release by the Board of Directors of West Coast Silver Limited.
