The past twelve months have been a defining chapter in our journey. In November 2024, shareholders overwhelmingly supported the Company’s rebranding from Errawarra Resources Ltd to West Coast Silver Limited, reflecting our strategic pivot to become Australia’s pre-eminent pure-play silver explorer. This transformation centred on our flagship asset—the Elizabeth Hill Silver Project in the Pilbara—which continues to demonstrate exceptional high-grade silver potential and district-scale opportunity. Our exploration strategy has been aggressive and targeted. The inaugural diamond drilling campaign at Elizabeth Hill commenced in Quarter 2 2025 and has already delivered exceptional results. Early drilling confirmed the presence of multiple mineralised zones in and around the historic mine, with laboratory assays from the first two holes confirming strong silver grades alongside anomalous copper and gold. These results validate our geological model and strengthen confidence in the system’s scale and continuity. These technical milestones were made possible by the strong support of our shareholder base. During the year, the Company completed a series of well-supported capital raisings, securing the funding required to accelerate drilling and unlock the potential of the Elizabeth Hill silver corridor. These placements brought in a strong mix of institutional and sophisticated investors aligned with our long-term vision. Importantly, the Company has remained committed to disciplined capital management and transparent communication throughout this journey. We thank our shareholders for their continued belief in our strategy and look forward to rewarding that trust with sustained progress. Looking ahead, West Coast Silver is positioned for an exciting growth phase. With our focused silver strategy, rejuvenated brand, and a high-grade asset at the core, we are building momentum as a new force in the Australian silver sector. On behalf of the Board, I extend my sincere thanks to our team, shareholders, and partners for their ongoing support. We look forward to delivering another transformative year ahead. Kind regards, Bruce Garlick Executive Chairman WEST COAST SILVER LIMITED 2025 ANNUAL REPORT | 2 DIRECTORS’ REPORT REVIEW OF OPERATIONS During the year West Coast Silver, acquired the historic Elizabeth Hill Silver Mine marking a significant change in the exploration focus for the company. This transformational acquisition ensures that the Company is now underpinned by a high-grade historical producing silver asset, with significant resource growth potential and future low-cost operational opportunities in a Tier One global mining jurisdiction. This acquisition was also the impetus for Errawarra Resources Ltd to be renamed West Coast Silver Limited which was approved by shareholders in May 2025. With the company’s primary focus being on Elizabeth Hill, the company has been reviewing its project portfolio and has disposed of foundation project tenements in the Fraser Range region. However, the company has maintained its strong tenure in the Gascoyne region with the focus being the Olsen gold target currently being investigated by Falcon Metals Ltd by way of a Joint Venture. Despite the current market sentiment towards nickel and lithium, the company considers its Andover West project which covers 100km2 to be valuable due to its proven prospectivity for nickel and lithium and more recently gold at the White Quartz Hill orogenic gold prospect. The Company’s projects are: Elizabeth Hill Silver Project West Coast Silver acquired 70% of the historical Elizabeth Hill Silver Project (“Elizabeth Hill”), 70% of the silver rights to the Pinderi Hills Project tenement package and 70% of the ownership of three tenements or tenement applications surrounding the silver project. This collective tenement package totalling 180km2 is in the Tier 1 mining jurisdiction of the Pilbara, Western Australia. Andover West (Nickel, Gold, Lithium) Project West Coast Silver acquired an 80% interest in the Andover West project on 2 May 2022 following shareholder approval at a meeting held 22 April 2022. The Company’s interest was acquired by way of an 80% interest in Western Exploration Pty Ltd, the owner of the project tenement. Errabiddy Project West Coast Silver holds interests in five tenements which comprise the Errabiddy project in the Gascoyne Region of Western Australia. Falcon Metals Ltd (ASX: FAL) is earning up to 70% interest in tenement E09/2457 by way of a Farm-in/Joint Venture (“JV”). West Coast Silver has an 80% interest in tenement E09/2346 with Sammy Resources free carried to the completion of a feasibility study at 20%. The remaining three tenements are held 100% by West Coast Silver. Binti Binti / Gindalbi (Gold) Project West Coast Silver currently holds 80% interest in granted tenement E27/577 located in the Edjudina Region of Western Australia 70km north-east of Kalgoorlie. 3 | WEST COAST SILVER LTD 2025 ANNUAL REPORT DIRECTORS’ REPORT Pinderi Hills JV (Lithium) Project West Coast Silver withdrew from its JV with Alien Metals Australian in which it had the right to earn 50% interest in the Pinderi Hills Project tenements by sole funding $4m in exploration within 4 years. Fraser Range Project West Coast Silver has surrendered its interests in two adjoining tenements in the Fraser Range Region of Western Australia. These interests were by way of an agreement with Sorrento Resources Pty Ltd and represented a 70% interest in both E63/1771 and E63/1941. Figure 1.

WEST COAST SILVER LIMITED 2025 ANNUAL REPORT | 6 DIRECTORS’ REPORT EXPLORATION Elizabeth Hill Silver Project (A) Introduction West Coast Silver acquired 70% of the historical Elizabeth Hill, 70% of the silver rights to the Pinderi Hills Project tenement package and 70% of the ownership of 3 tenements or tenement applications surrounding the silver project. This collective tenement package totalling 180km2 is in the Tier 1 mining jurisdiction of the Pilbara, Western Australia. The Elizabeth Hill Project acquisition resulted in West Coast entering into separate joint venture agreements with Alien Metals Australia (AIM: UFO) (“Alien”) and GreenTech Metals Limited (ASX: GRE) (“GreenTech”). This transformational acquisition ensures that the Company is now underpinned by a high-grade historical producing silver asset, with significant resource growth potential and future low-cost operational opportunities in a Tier 1 global mining jurisdiction. (B) Background Elizabeth Hill, one of Australia’s high-grade silver projects has a proven production history which included the recovery of numerous nuggets. Figure 2. Elizabeth Hill location 7 | WEST COAST SILVER LTD 2025 ANNUAL REPORT  1.2Moz of silver was produced from just 16,830t of ore at a head grade of 2,194g/t (70 oz/t Ag);  Previous mining operation ceased in 2000 because of low silver prices (~US$5oz);  Silver was recovered via low-cost gravity separation techniques; and  Tier 1 Mining Jurisdiction located on a granted mining lease with potential processing option at the nearby Radio Hill site. DIRECTORS’ REPORT (C) Acquisition terms and details Alien Under its agreement with Alien, West Coast Silver agreed to acquire from Alien 70% of the Elizabeth Hill mining lease and 70% of the silver mineral rights to the Pinderi Hills tenement package. The Consideration for the Alien Transaction was $500,000 cash to Alien; and the issue of 44,500,000 shares. The key terms of the Alien JV Agreement in respect of both the Elizabeth Hill tenement and the Pinderi Hills tenements are as follows: (a) On and from the date of completion of the Alien Transaction, West Coast and Alien (together, the “JV Parties”) established and commenced the joint venture and hold the joint venture interests on a 70/30 basis. (b) On and from the JV Start Date, West Coast agreed to solely fund all joint venture expenditure and free carry Alien’s joint venture interest until a Decision to Mine; and (c) Upon a Decision to Mine, Alien must elect within 10 business days to: Green Tech  convert its joint venture interests to a 2% net smelter royalty: or  contribute to all joint venture expenditure made or incurred in respect of the joint venture in proportion to their respective joint venture interests and where either JV Party does not contribute to the joint venture expenditure Its joint venture interest will dilute in accordance with the formulae set out in the Alien JV Agreement (as the case may be). Under its agreement with GreenTech, West Coast Silver agreed to acquire from GreenTech 70% of the ownership of 2 tenements and 1 tenement application which adjoin the Elizabeth Hill silver project. The Company paid $100,000 cash to GreenTech as consideration for the Transaction. The key terms of the GreenTech JV Agreement are: (a) On the Completion Date, West Coast and GreenTech established and commenced the joint venture and hold the joint venture interests on a 70/30 basis. (b) On and from the JV Start Date, West Coast agreed to solely fund all joint venture expenditure and free carry GreenTech’s joint venture interest in the joint venture until West Coast announces a Decision to Mine (“Free Carried Period”). (c) During the Free Carried Period, West Coast agrees to incur a minimum of $1,000,000 in joint venture expenditure within four years of the JV Start Date, unless otherwise extended by mutual agreement between the parties. (D) Geological setting A characteristic of the West Pilbara terrain is the extensive occurrence of mafic intrusions and in many instances related nickel-copper mineralisation. This association is fundamental to the nickel-copper prospectivity of the region. The historic Elizabeth Hill underground silver mine is located between two mafic intrusives namely the Munni Munni and Maitland mafic layered intrusions which present at surface as gabbro and peridotite. Both intrusives are prospective for Nickel-Copper and PGE mineralisation. Elsewhere the project area is mostly dominated by the Nallana Formation with lesser occurrences of the Toorare Tonalite and with a small occurrence of the South Whundo Granodiorite. WEST COAST SILVER LIMITED 2025 ANNUAL REPORT | 8 DIRECTORS’ REPORT The major mineralisation styles present in and around the project area can be subdivided into several main groups:  Vein and Hydrothermal mineralisation: gold, copper-gold and silver.  Orthomagnetic mafic-ultramafic mineralisation that includes commodities such as nickel, copper, cobalt, Platinum Group Elements (“PGE”), vanadium, titanium and chromium.  Volcanogenic Massive Sulphide (“VMS”) mineralisation: copper, lead, zinc, silver and gold. Specifically, within the project area the primary focus of exploration for the Company is the first mentioned style of mineralisation above due to the presence of a very significant high-grade silver dominant polymetallic hydrothermal style deposit. This deposit known as Elizabeth Hill was mined in the 1998-2000 period with reported production of 1.16Moz silver from just 16,830t of ore. The silver deposit is spatially associated with the Munni Munni Fault which is a major north south trending fault structure in the area. Along with the Munni Munni Fault are numerous similarly orientated faults that appear to be sympathetic structures and which could be equally prospective for silver mineralisation. This along with other evidence indicates that the project area is highly prospective for look-a-like Elizabeth Hill style mineral deposits. (E) Exploration DRILLING An inaugural drill program comprising 12 diamond core holes for a total 1,183m was completed during June 2025 with assay results received for 6 of the 12 drill holes. Of the assay results received to date for these 6 drill holes (25WCDD001, 25WCDD002, 25WCDD003, 25WCDD004, 25WCDD011 and 25WCDD012), exceptionally shallow, high grade silver results were returned for 25WCDD011 and 25WCDD0121. Both holes intersected significant silver mineralisation from near surface, with particularly impressive results from hole 25WCDD011 which intersected: Drill Hole 25WCDD011  17 metres at 858g/t Ag from 5 metres including: 2 metres at 6,349g/t Ag from 7 metres;  10 metres at 850g/t Ag from 47 metres including: 3 metres at 2,593g/t Ag from 50 metres; and  13 metres at 1,615g/t Ag from 62 metres including: 2 metres at 10,049g/t Ag from 63 metres. Drill Hole 25WCDD012 Figure 3. Long section showing drill holes, 25WCDD001, 25WCDD002, 25WCDD004, 25WCDD011 & 25WCDD012 1 Refer to West Coast Silver ASX announcement dated 22 August 2025. 9 | WEST COAST SILVER LTD 2025 ANNUAL REPORT  6 metres at 317g/t Ag from 10 metres including: 1m at 1,455g/t Ag from 13 metres. DIRECTORS’ REPORT Drill Hole 25WCDD001  20m at 1,097g/t Ag from 10mmetres including: 8m at 2,629 g/t Ag from 22metres; and 1m at 15,071 g/t Ag from 27metres Drill Hole 25WWCDD002  15m at 729g/t Ag from 1metre including: 3m at 2,639g/t Ag from 1metre and 1m at 2.03g/t Au from 4metres Drill hole 25WCDD011, which was strategically drilled to test depth and continuity of the mineralisation also intersected significant high grade gold mineralisation including 1 metre at 11.1g/t Au. Along with significant silver and gold mineralisation, native silver has also been identified in 25WCDD011. This development has initiated investigations within the company into Figure 4. Plan view of 2025 West Coast Silver Diamond core drilling and historical drilling the viability of a simplistic gravity separation process to recover free silver from the Elizabeth Hill mineralisation. Elizabeth Hill is located 25km south of an existing processing facility at Radio Hill which is owned by Artemis Resources Ltd. Utilisation of these facilities will be factored in the company’s assessment of the potential processing options for the Elizabeth Hill material. SOIL SAMPLING AND GEOLOGICAL MAPPING A systematic soil sampling program targeting distal anomalies is currently underway and progressing on schedule and with samples being dispatched to the laboratory on a progressive basis. Complementing the soil sampling, geological and structural mapping of the broader Elizabeth Hill area has also commenced. This work is aimed at refining geological models and improving the understanding of controls on mineralisation. ROCK CHIP SAMPLING A reconnaissance rock chip and float sampling program, which involved the collection of 115 rock chip/float samples, has returned significant assay results, confirming the presence of anomalous silver, copper, and gold mineralisation in areas both north and south of the historic Elizabeth Hill high-grade silver mine. Notable assay results from the complete results include:  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, 0.1% Cu; WEST COAST SILVER LIMITED 2025 ANNUAL REPORT | 10 DIRECTORS’ REPORT These significant assay results – up to 490 g/t Ag, 0.19 g/t Au, and 0.42% Cu – occur in two key areas relative to the historic high-grade silver mine. A cluster of samples grading >100 g/t Ag are located over an area 200–500 m north of the mine, while an isolated sample (170 g/t Ag) lies ~200 m to the south. The results suggest potential for additional new mineralised source areas and are possibly related to the north-south trending Munni fault system. Figure 5. Location of float sample assay results north and south of the historic Elizabeth high grade silver mine INTEGRATED TARGETING STUDY An integrated targeting study has delivered significant advancement in West Coast Silver’s geological understanding of the Elizabeth Hill. Data sets investigated in this study include:  Historical near mine and regional drill hole data;  Historical soil, multi-element geochemical data;  West Coast Silver rock chip and float sample multi-element geochemical data;  Review of historical trench geochemical data; and  Historical magnetic, radiometric and gravity data. The analysis of the integrated data sets confirms the primary control on high-grade silver mineralisation at Elizabeth Hill is the intersection of the Munni fault with the granite–ultramafic rock contact, a structurally favorable setting known to host significant mineralisation at the historical Elizabeth Hill underground mine. The re-evaluation of a large volume of historical and recent data sets led to the identification and ranking of 12 high priority targets on near-mine tenements. These targets were assessed based on the following criteria: 1. Proximity to key structural features such as north-trending faults and fault flexures. 2. Proximity to granite/ultramafic rock contacts. 3. Coherent silver-in-soil anomalies with multi-element support (including copper and zinc). 4. Presence of gossanous material or historical float samples with elevated silver. 5. Underexplored zones due to ineffective past drilling or transported cover in regolith. 11 | WEST COAST SILVER LTD 2025 ANNUAL REPORT DIRECTORS’ REPORT The 12 near-mine targets remain untested or ineffectively tested, particularly those to the south of the historic mine where the main silver shoot is interpreted to step down along east-trending faults. This step-down geometry provides a compelling exploration narrative for the search for extensions of the high-grade silver mineralised zone. HIGH PRIORITY EXPLORATION TARGETS – NEAR MINE The target generation study has defined two near mine targets for immediate follow up exploration. One near mine target is located along the interpreted Munni Munni fault at the granite/ultramafic rock contact to the south of the Elizabeth Hill Silver Mine. It is supported by two very high-grade silver intersections in historical drill holes AG43 (1m @ 250g/t Ag from 118m downhole depth) and AMEHRC012 (2m @ 1,550g/t Ag from 108m downhole depth). A second near mine target is located about 100m north of the historical Elizabeth Hill Silver Mine along the interpreted Munni fault. This target is supported by one silver intersection in historical drill hole 22AMC011 (4m @ 60g/t Ag from 4m downhole depth) within a granite host rock and surrounded on the surface by three highgrade float samples and one high-grade rock chip sample. Figure 6. Further top 76 targets along the east side of the Munni Munni intrusion (Overlaid on RTP Band Pass Filter Tilt Magnetic Image) Several other high priority targets are located at the eastern contact of the Munni Munni ultramafic/mafic intrusion and eastern granite These targets are supported by silver in soil anomalies and are located along an interpreted fault paralleling the eastern margin of the ultramafic/mafic Munni Munni intrusion in a similar structural position and host rock setting to the Elizabeth Hill Silver Mine.

With respect to Azure’s lithium pegmatite discovery, which is currently undergoing resource drill out, Azure announced a lithium resource target of 100-240mt @ 1-1.5% Li2O. Because of the proximity to Azure’s discovery West Coast Silver pursued the discovery and evaluation of lithium pegmatites which had also been identified within the Company’s project tenement. The Company’s exploration activities for both nickel and copper have subsequently been curtailed due to market sentiment towards these commodities. However, the project tenement remains prospective for gold at the White Quartz Hill orogenic gold prospect where the company has undertaken reconnaissance sampling. (B) Background West Coast Silver received approval from shareholders to complete the Andover West transaction with Western Exploration Pty Ltd at a General Meeting held 22 April 2022. This was achieved by acquiring 80% interest in private company Western Exploration Pty Ltd the holder of tenement application E47/4352 which comprises the project. The tenement was initially acquired to explore for mafic hosted nickel deposits within the mineralised and highly prospective Andover Mafic Intrusion. Subsequently the exploration was broadened to include lithium bearing pegmatites following the discovery of lithium bearing (“LCT”) pegmatites by Azure on their adjoining tenement. More recently the company has been investigating the White Quartz Hill orogenic gold prospect. (C) Geolo
