West Coast Silver is pleased to present the Company’s quarterly activities report for the quarter ending 30 September 2025 (“the Quarter”). During the 1st Quarter (July – September 2025): The primary focus of the Company’s activities over the Quarter was on the Elizabeth Hill Silver Project where the subsequent assays from the inaugural drilling campaign delivered some further exceptional results including a spectacular 2 m interval grading 10,049g/t Silver (Ag) from 63 m in hole 25WCDD011. West Coast owns 70% of the historical Elizabeth Hill Silver Project (“Project”or“Elizabeth Hill”), 70% of the silver rights onsix tenements forming the Pinderi HillsProject, and 70% ownership of threetenementsand one tenement application surrounding the Project. This collective tenement package totalling 180km2 is in the Tier 1 Pilbara mining region of Western Australia. Commenting on the quarter, Executive Chairman Bruce Garlick said: “The assay results received in this quarter from the inaugural drilling campaign confirm the presence of high silver grades from our exploration program at Elizabeth Hill. We have intersected further high-grade silver from close to surface in subsequent holes”. “As a result, we have commenced a 1,300m diamond drilling program at the Elizabeth Hill mine site, and a 2,000- 3,000m air core program is being planned at the high priority targets near to the mine site.” “During the Quarter, after a heavily oversubscribed $6.125 million capital raising, we are now in a position to advance into demonstrating the near-surface continuity in the oxide zone and test a higher conviction deeper target that could represent a down-plunge repeat of the Elizabeth Hill system.” ASX: WCE ANNOUNCEMENT 29 October 2025 3 ASX | WCE WEST COAST SILVER LIMITED westcoastsilver.com.au • Exceptional initial drill results: The first two holes of the inaugural 12-hole diamond program (1,183 m) at Elizabeth Hill returned spectacular near-surface intercepts. Hole 25WCDD001 yielded 21 m @ 1,047 g/t Ag from 10 m and included 8 m @ 2,632 g/t Ag from 22 m and an interval of 1 m @ 15,071 g/t Ag from 27 m. Hole 25WCDD002 recorded 15 m @ 723 g/t Ag from 1 m including 3 m @ 2,639 g/t Ag from 1 m and a gold intercept of 1 m @ 2.03 g/t Au from 4 m1 . • High-grade follow-up intercepts: Subsequent assays from the inaugural program delivered further exceptional results2 as follows: • 25WCDD011 intersected 17 m @ 858 g/t Ag from 5 m including 2 m @ 6,349 g/t Ag from 7 m, 10 m @ 850 g/t Ag from 47 m and 13 m @ 1,615 g/t Ag from 62 m including 2 m @ 10,049 g/t Ag from 63 m. The hole also returned 1 m @ 11.1 g/t Au from 51 m. • 25WCDD012 returned 6 m @ 317 g/t Ag from 10 m (including 1 m @ 1,455 g/t Ag from 13 m) and 14 m @ 162 g/t Ag from 18m. • Additional high-grade intercepts: Further high-grade results were announced from holes 25WCDD008 and 25WCDD0103 . 25WCDD008 intersected 6 m @ 316 g/t Ag from 44 m, including 1.4 m @ 1,007 g/t Ag from 45 m, and a separate interval of 21 m @ 50 g/t Ag from 20 m. 25WCDD010 returned 3.4 m @ 219 g/t Ag from 63 m. • Phase 2 Drilling Commenced at Elizabeth Hill: Subsequent to quarter end, Phase 2 diamond drilling commenced on 11 October 2025. The program aims to test near surface high-grade silver mineralisation and prospective areas at depth below existing workings. The Phase 2 drilling program will consist of approximately 14 diamond holes (~1,300 m). This will be expanded as required based on the success of the program. In addition, geophysical surveys have been completed to provide additional high-quality data for refinement of the proposed aircore program scheduled to commence in November. • Reconnaissance rock-chip program: A 115-sample rock-chip and float sampling campaign around Elizabeth Hill returned significant assays with silver up to 490 g/t, copper up to 0.42% and gold up to 0.19 g/t. High-grade silver samples cluster between 200–500 m north and ~200 m south of the historical mine4 . • Integrated targeting study: An integrated geophysical, geochemical and geological study led by The ERM Geoscience team identified 12 high-priority near-mine targets and eight regional targets5 . The study highlighted the importance of the Munni Munni fault and the granite–ultramafic contact and ranked targets based on structural proximity and multi-element geochemical support. • Growth potential: Regional targeting for look-a-like Elizabeth Hill silver deposits within large 180km2 land package. Inaugural Drill Program & Historical Drilling Assessment During the quarter, West Coast Silver completed its maiden diamond drilling program at Elizabeth Hill.

The integrated targeting study concluded that this setting is structurally favourable. Visible native silver and silver sulphide minerals were identified in quartz–calcite veins within pyroxenite, suggesting potential for gravity separation. Mineralisation occurs both in the oxide zone near surface and in underlying sulphide zones, with the highest grades associated with narrow native silver veins. Data indicates that mineralisation plunges southwards along the fault and remains open at depth9 . Drilling Logistics and Sampling Core samples were dispatched to accredited laboratories under strict chain-of-custody procedures. Logging and sampling of the final holes continued into July, with assays received over the preceding 6–8 weeks. Quality assurance included insertion of standards, blanks and duplicates, as documented in the JORC 2012 Table 1. The Competent Person for the release of this data confirmed the historical data had been verified and was fit for purpose (Appendix 4 of the 5 August 2025 ASX Announcement). Rock-Chip and Float Sampling During July 2025, the Company completed a reconnaissance rock chip sampling program collecting 115 rock chip and float samples from around Elizabeth Hill. The program returned silver up to 490 g/t, gold up to 0.19 g/t and copper up to 0.42%. Stand-out samples included 25EW06-062 (490 g/t Ag, 0.03 g/t Au, 0.17% Cu); 25EW06-057 (316 g/t Ag, 0.19 g/t Au, 0.11% Cu); 25EW06-063 (276 g/t Ag, 0.13 g/t Au, 0.14% Cu); 25EW06-025 (179 g/t Ag, 0.42% Cu); and 25EW06-064 (178 g/t Ag, 0.10% Cu). High-grade samples cluster north and south of the historical mine indicating potential extensions along the Munni Munni fault10 . These results underpinned the prioritisation of near-mine targets NM1 and NM59 . 9 Refer to West Coast Silver’s ASX announcement “Near Mine High Priority Targets Defined at Elizabeth Hill” dated 5 August 2025. 10 Refer to West Coast Silver’s ASX Announcement “Amended Significant Fieldwork Assays from Elizabeth Hill” dated 24 July 2025. ASX: WCE ANNOUNCEMENT 29 October 2025 6 ASX | WCE WEST COAST SILVER LIMITED westcoastsilver.com.au Integrated Targeting Study ERM’s integrated study synthesised historical drill holes, soil data, West Coast Silver’s rock-chip results, trench data and reprocessed geophysics. The study concluded the intersection of the Munni Munni fault with the granite– ultramafic contact is the primary control on high-gradesilver mineralisation. Twelvehigh-priority near-mine targets were identified and ranked using criteria including proximity to faults and contacts, presence of silver in historical soil samples from multi-element geochemical data and evidence of gossanous material. Two targets, NM1 and NM5, were prioritised for immediate follow-up. NM1 is ~100 m north of the mine and is supported by high-grade float/rock-chip samples and a historical intercept of 4 m @ 60 g/t Ag from 4 m in 22AMC011. NM5 lies south of the mine along the Munni Munni fault and is underpinned by historical drill results of 1 m @ 250 g/t Ag from 118 m (AG43) and 2 m @ 1,550 g/t Ag from 108 m (AMEHRC012)11 . Operational Impact and Next Steps On 11 October 2025, West Coast Silvercommenced Phase 2 diamond drilling at the high-grade Elizabeth Hill Silver Project in the Pilbara region of Western Australia. The program follows on from multiple very high grade silver intercepts from the Phase 1 drilling reported in August and September 2025. This new drilling is designed to: • Confirm and define shallow, high-grade silver mineralisation immediately adjacent to the historical workings; and • Test a high-conviction deeper target interpreted as a potential down-plunge repeat of the Elizabeth Hill Mine sequence. The Phase 2 program comprises approximately 14 diamond holes (~1,300 m) and will be expanded subject to results. Drilling is being undertaken by Wallis Drilling Pty Ltd. In parallel, Transient Electromagnetic (“TEM”) and drone magnetic surveys have been completed, with data processing underway to refine aircore targets scheduled for November 2025. Ongoing and Planned Fieldwork Field mapping of the 12 near-mine targets was competed in September 202512 . A drone magnetic survey along the Munni Munni fault is planned to collect detailed high-resolution data to aid in identifying potential magnetic signatures akin to that associated with the Elizabeth Hill orebody. A Loupe TEM survey to test for near surface conductive anomalies is also planned. The phase 2 drill program will test near surface and deeper targets, and results will feed into a maiden Mineral Resource estimate. 11 Refer to West Coast Silver’s ASX announcement “Near Mine High Priority Targets Defined at Elizabeth Hill” dated 5 August 2025. 12 Refer to West Coast Silver’s ASX announcement “Exploration Ramped Up at Elizabeth Hill” dated 2 September 2025.

Figure 3- Location of float samples assay results north and south of the historical Elizabeth Hill high grade silver mine Forward Work Plan West Coast Silver has outlined a multi-faceted work plan for FY2026: • Mapping and geophysics: Detailed mapping of 12 near-mine targets was completed by structural geologist Dr Peter Neumayr. Geophysical surveys planned for October include a drone magnetic survey along the Munni Munni fault to collect detailed high-resolution data and Loupe TEM survey to test for near surface conductive anomalies. • Phase 2 drilling: A contract with Wallis Drilling was signed for ~1,000 m of diamond drilling and 2,000– 3,000 m of aircore drilling. The diamond drilling was scheduled to commence in the second week of October and will test near-surface mineralisation, depth extensions and step-out targets. • Resource definition: ERM is working to quantify near-surface mineralisation for a potential open-pit resource and will conduct QA/QC on historical data. • Processing studies: Discussions have been initiated with Artemis Resources Limited regarding use of the Radio Hill plant and its Gekko gravity circuit. • Community engagement and approvals: Ongoing heritage and environmental assessments will support permitting for phase 2 drilling and future project development. 14 Refer to West Coast Silver’s ASX announcement “Near Mine High Priority Targets Defined at Elizabeth Hill” dated 5 August 2025. ASX: WCE ANNOUNCEMENT 29 October 2025 10 ASX | WCE WEST COAST SILVER LIMITED westcoastsilver.com.au Figure 4 - Regional Prospectivity at Elizabeth Hill 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: 1.2M oz of silver was produced from just 16,830 t of ore at a head grade of 2,194 g/t (70.5 oz/t Ag)15 . • Previous mining operation ceased in 2000: because of low silver prices (US$5)16 • 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 locatedon a mining lease with potential processing option at the nearby Radio Hill site. 15 WAMEX Annual Report,1 April 2014 to 31 March 2015, Elizabeth Hill Silver Project, Global Strategic Metals NL, p16. 16 www.kitco.com/charts/silver ASX: WCE ANNOUNCEMENT 29 October 2025 11 ASX | WCE WEST COAST SILVER LIMITED westcoastsilver.com.au Figure 5 – Location of Project Combined Tenements 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. • 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. • The Company terminated its lithium joint venture with Alien Metals Ltd at the Pinderi Hills Project to focus on silver17 . 17 Refer to West Coast Silver’s ASX Announcement “Amended Significant Fieldwork Assays from Elizabeth Hill” dated 24 July 2025. Other Projects ASX: WCE ANNOUNCEMENT 29 October 2025 12 ASX | WCE WEST COAST SILVER LIMITED westcoastsilver.com.au • During the quarter Falcon Metals Ltd, West Coast’s JV Partner completed an infill soil sampling program on E09/2457 that further refined the targets for an upcoming RC Program with a focus on the Olsen Well gold in soil anomaly18 . The Errabiddy project comprises 7 tenements with a combined area of approximately 1,000km2 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 Minerals 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 220km northwest of Meekatharra in Western Australia. The 519km2 licence covers a 42km 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 4km spaced geochemical grid, detected a 6 ppb Au anomaly near Olsen Well. The sampling undertaken by West Coast Silver in 2023 has shown the Olsen Well Prospect is a significant gold in soil anomaly with a surface extent of 3km x 1km 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. During the quarter, Falcon continued with its reconnaissance and soil sampling activities collecting 272 ultrafine samples. This consisted of infill sampling following up on previous results and extensional sampling that was successful in increasing the strike length of the anomaly, at a >10 ppb Au threshold, from 3 km to 5.8 km. Although these results were generated during the quarter and have assisted in progressing the Olsen Well Prospect, they do not change Falon’s planned work program at the Project. Once the final phase of the rock chip sampling is completed, a heritage survey will be undertaken ahead of the first ever drilling program at Olsen Well. Lithium Potential The Andover West Project is located 30km south-east of Karratha with exploration initially targeting only mafic intrusion hosted nickel-copper mineralisation. However, the significant Lithium-Caesium-Tantalum (“LCT”) pegmatite discoveries reported by Azure Minerals and their ongoing evaluation highlighted the potential for LCT pegmatite on West Coast Silver’s adjoining tenement. West Coast Silver subsequently identified two prospective lithium pegmatite swarms19 within its project tenement located along strike of the discoveries made by Azure 18 Refer to Falcon Metals’ ASX Announcement “Soil anomaly extended to 5.8km strike at Errabiddy” dated 22 July 2025. 19 Refer to ASX Announcement “Mount Oscar Joint Venture Progress Report” dated 13 May 2024. Errabiddy Falcon JV Andover West ASX: WCE ANNOUNCEMENT 29 October 2025 13 ASX | WCE WEST COAST SILVER LIMITED westcoastsilver.com.au Minerals. Despite the prospectivity for LCT pegmatites the Company has not progressed the exploration due to the significant retreat of the lithium price. Gold Potential A review of the gold potential within tenement E47/4352 identified the White Quartz Hill (WQH) Prospect where Fox Resources has previously reported the occurrence of gold associated with structures over a strike of 5km20 . The Binti Binti/Gindalbie Gold Project comprises sole tenement E27/577. The tenement has significant gold prospectivity with a new potential gold anomalous zone identified. While investigation of this new gold target area is continuing, the Company is also assessing corporate opportunities with respect to this Project. • Cash balance at the end of the quarter was $5.122 million. • Completed a $6.125 million (before costs) share placement to a broad range of new institutional and sophisticated investors21 . • The Placement was priced at $0.11 per share representing a premium of 0.04% to the 15-day VWAP to 21 July 2025. • Matt Birney was appointed as a Non-Executive Director22 , and Robert Mosig resigned as a Non- Executive Director23 . • The Annual General Meeting of the Company will be held on 20 November 2025 at 10.00am (WST) at Level 2, 10 Ord Street, West Perth WA 6005. The Notice of Meeting has been dispatched electronically or by mail depending on shareholders’ communication preferences24 .
