West Coast Silver Releases Elizabeth Hill Dhem Target Update Alien Metals Limited advised that its joint venture partner, West Coast Silver Limited released an announcement titled 'Elizabeth Hill Silver Project: New High Priority Target to be Drill Tested'. The attached West Coast Silver release outlines the identification of a new DHEM conductor target at the Elizabeth Hill Project, located approximately 50 metres east of the Elizabeth Hill Mine and at a depth of around 110 metres, which West Coast Silver intends to drill test immediately. The first Down Hole Electromagnetic (DHEM) data has been received and processed from the Elizabeth Hill Mine Project. A DHEM conductor has been identified, 50 metres to the east of the Elizabeth Hill Mine and 110 metres depth. The anomaly is represented by a discrete modelled plate (dimensions 20-100 metres by 60 metres) which has not been previously drill tested. Historic drill hole AG54, which intersected 2m at 42 g/t Ag, is situated 25 metres up-dip and aligned with the plate model. The conductance and position of the plates present a compelling drilling target. The Diamond drill rig onsite will move immediately to test the DHEM anomaly, with drilling expected to be completed in the coming week. This first use of electromagnetics by West Coast Silver at Elizabeth Hill which supports the effectiveness of the technique in identifying conductive drill targets. Further surface geophysics techniques are currently being trialled over the Elizabeth Hill deposit. Assay results from Reverse Circulation (RC) and Diamond Drill (DD) programs are anticipated to be received progressively throughout Second Quarter 2026. Hole 25WCDD0025 from West Coast Silver drill program in 2025 was cased with PVC earlier in the year as part of the preparation for trialling DHEM. The DHEM program was designed to test whether direct targeting of high-grade silver mineralisation could be achieved. The results from the current survey indicate: The conductance values of the identified DHEM plates (400-1,200 Siemens) are consistent with the expected range for target silver mineralisation as indicated by petrophysical studies conducted earlier in 2026. While other factors could account for the observed conductivity, the context, intensity, and position of the plates present a compelling drilling target. The upper edge of the plate is located roughly 110 metres beneath the surface and about 50 metres east of the Elizabeth Hill Mine. The modelled conductive plate has a discrete area 60m in the north-south plane and 20 to 100 metres down-dip. No other drilling has been conducted at this depth within the area. All prior drilling was positioned above or passing above this target zone, drilling westward away from this target towards the main Munni Munni Fault. A single drill hole planned from an existing drill pad to directly target the modelled plate at approximately 150 to 170 metres downhole depth. Since the geophysical target has not yet been directly intersected by prior drilling, it remains uncertain whether the drill hole conductor anomaly reflects the same quality, quantity, or mineralogy as observed at Elizabeth Hill Mine. These factors will only be confirmed through the forthcoming drill hole that will test the anomaly. West Coast Silver is conducting multiple exploration programs planned to end of May 2026, comprising reverse circulation drilling, diamond drilling, Down Hole and surface geophysics. The diamond drill rig is moving to test the DHEM anomaly with drilling expected to be completed in the coming week. Should mineralisation be intersected then cutting logging and assaying will be completed over Second Quarter 2026. Elizabeth Hill is historically one of Australia's highest grade silver projects and has a proven production history. High grades enabled low processing tonnes. A total of 1.2 Moz of silver was produced from just 16,830t of ore at a head grade of 2,194g/t (70.5 oz/t Ag). Mining operations ceased in 2000 as a result of low silver prices ($5). Simplistic historic processing techniques were used focussing only on native silver extraction. Native silver was recovered via low-cost gravity separation techniques. Untapped mineral resource expansion potential remains. The Elizabeth Hill deposit remains open at depth and along strike. Recent consolidation of the WCE tenement land holding offers potential to discover more Elizabeth Hill style deposits near mine and regionally. World leading silver grades located on a mining lease with potential processing option at the nearby Radio Hill site. Through the consolidation of surrounding land packages into a single contiguous 180km2 package, significant exploration and growth potential has been created 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 silver deposit analogues.

Alien Metals Limited Commences Diamond Drilling for High-Grade Silver Extensions Below the Elizabeth Hill Mine Alien Metals Limited advised that its joint venture partner, West Coast Silver Limited announced that an up to 1,500m (six holes) diamond drilling (DD) program has commenced at the Elizabeth Hill Silver Project near Karratha, in the Pilbara region of Western Australia, targeting areas directly below and next to the underground mine, where drilling in 2025 showed that silver extends to the surface. Drilling is expected to take between four and six weeks and results are expected to be received progressively through the Second Quarter 2026. West Coast Silver Limited announced an up to 1,500m diamond drilling (DD) program has commenced at its flagship Elizabeth Hill silver project in the Pilbara region of Western Australia. The drilling is designed to expand the existing footprint of the Elizabeth Hill high-grade silver mineralisation down-dip and plunge of the historical Elizabeth Hill silver mine. This program represents the first systematic test of the Company's structural model that suggests high-grade silver mineralisation may repeat at depth along the Munni Munni Fault, which, if confirmed, could materially expand the scale of the Elizabeth Hill system beyond the historical mine. The DD program will specifically probe between and around historical drilling results along the Munni Munni Fault. Previous drilling intersected moderate to high-grade silver mineralisation, justifying follow-up to confirm depth potential, continuity, grade and distribution of intercepted zones. All holes are designed to intersect the Munni Munni Fault within approximately 200m of surface. Drilling is expected to take approximately four to six weeks, subject to weather and operational conditions. Assay results are anticipated to be received progressively through the Second Quarter 2026. Exploration Next Steps West Coast Silver is running multiple exploration programs from end of March to end of May 2026, comprising reverse circulation drilling, diamond drilling, borehole and surface geophysics. Focus through the next three months of exploration activities will be on processing, interpreting and reporting results, as well as dynamic repositioning of remaining planned drill holes to maximise chances of success from results received (geological, geophysical and assay results). Elizabeth Hill is historically one of Australia's highest grade silver projects and has a proven production history. High grades enabled low processing tonnes. A total of 1.2 Moz of silver was produced from just 16,830t of ore at a head grade of 2,194g/t (70.5 oz/t Ag). Mining operations ceased in 2000 as a result of low silver prices (USD 5).

Alien Metals Limited Announces Diamond Drilling Targeting High-Grade Silver Extensions Beneath Elizabeth Hill Mine Alien Metals Limited a minerals exploration and development company, has advised that its joint venture partner, West Coast Silver Limited (ASX: WCE), has announced that a 1,500m diamond drilling (DD) programme is to commence in early April 2026 at the Elizabeth Hill Silver Project near Karratha, in the Pilbara region of Western Australia. Up to 1,500m diamond drilling program (6 holes) to commence beneath the historic Elizabeth Hill high-grade silver mine, Pilbara Western Australia. First systematic test of deeper silver mineralisation along the Munni Munni Fault - the primary structural control on high-grade silver at Elizabeth Hill. Targets extensions directly below and along strike of the underground mine, where 2025 drilling confirmed silver mineralisation extends to surface. Following up high grade silver intersections from historical surface and underground drilling. All holes designed to intersect the Munni Munni Fault within 200m of surface. Testing the "Pearls on a String" exploration concept- that high-grade silver mineralisation repeats at regular intervals along the fault, which could materially expand the scale of the Elizabeth Hill system. Drilling is expected to take approximately four to six weeks. Assay results are anticipated to be received progressively through Second Quarter 2026. The drilling is designed to expand the existing footprint of the Elizabeth Hill high-grade silver mineralisation down-dip and plunge of the historical Elizabeth Hill silver mine. This program represents the first systematic test of the Company's structural model targeting potential repetition of high-grade silver mineralisation at depth along the Munni Munni Fault, which, if confirmed, could materially expand the scale of the Elizabeth Hill system beyond the historical mine. Drilling will test for extensions of mineralisation along strike of the historical Elizabeth Hill high-grade underground silver mine, and structural targets along the Munni Munni Fault. The Munni Munni Fault is a significant regional control on silver and base metal mineralisation. The DD program will specifically probe between and around historical drilling results along the Munni Munni Fault. Previous drilling intersected moderate to high-grade silver mineralisation, justifying follow-up to confirm depth potential, continuity, grade and distribution of intercepted zones. Drilling will also test the concept of high-grade mineralisation repeating at regular intervals with depth. This is the 'Pearls on a String' concept favouring structural repetition of mineralisation over strike and depth along the Munni Munni Fault. All holes are targeting to intersect the Munni Munni Fault within approximately 200m of surface. Initial DD will be to the south and down plunge of the historical Elizabeth Hill silver mine and then step-out to focus on areas south along the Munni Munni Fault. Drilling is expected to take approximately four to six weeks, subject to weather and operational conditions. Assay results are anticipated to be received progressively through Second Quarter 2026. West Coast Silver is running multiple exploration programs from end of March to end of May 2026, comprising reverse circulation drilling, diamond drilling, borehole and surface geophysics.

West Coast Silver Limited Announces Commencement of RC Drilling to Advance Elizabeth Hill Silver Project Alien Metals Limited (AIM: UFO), a minerals exploration and development company, has advised that its joint venture partner, West Coast Silver Limited (ASX: WCE) ("West Coast" or "West Coast Silver"), has announced that a 4,000m Reverse Circulation (RC) drilling program has commenced at the Elizabeth Hill Silver Project near Karratha, in the Pilbara region of Western Australia. Up to 4,000m Reverse Circulation (RC) drilling program has commenced at the Elizabeth Hill silver project in the Pilbara region of Western Australia. Initial drilling targets the northern extensions to the Elizabeth Hill silver mineralised system along the Munni Munni Fault (MMF). The RC program follows up high-grade grade silver intersections returned from 2025 drilling. All holes are targeted to intersect the MMF within ~150m of surface, a depth potentially amenable for open-pit mineable, low-cost resource growth. The RC program is designed to support expansion of the Elizabeth Hill mineralised footprint. Drilling includes extending areas directly up-dip and plunge of the Elizabeth Hill underground silver mine, defined in 2025 as being mineralised to surface. West Coast Silver Limited (ASX: WCE) ('West Coast Silver' or the 'Company') has announced an up to 4,000m Reverse Circulation (RC) drilling program has commenced at its flagship Elizabeth Hill silver project in the Pilbara region of Western Australia. The RC drilling is designed to expand the existing footprint of Elizabeth Hill high-grade silver mineralisation up-dip and plunge of the historical Elizabeth Hill silver mine. RC drilling will test for mineralisation extension along strike of the historic Elizabeth Hill high-grade underground silver mine and newly identified structural targets along the Munni Munni Fault (MMF). The MMF is a significant regional control on mineralisation. The RC program will specifically test for extensions of mineralisation north and northwest of 2025 diamond and aircore drilling results, as well as along the MMF at Elizabeth Hill North (EHN) and Elizabeth Hill South (EHS). Previous drilling at EHN and EHS intersected moderate to high-grade near-surface silver mineralisation justifying follow-up to confirm depth potential, continuity, grade and distribution of intercepted zones. All holes are targeting to intersect the MMF within approximately 150m of surface, highlighting the potential for rapid and cost-effective resource growth. Initial RC drilling will be to the north of the historical Elizabeth Hill silver mine and then focusing on areas south along the Munni Munni Fault. Drilling is expected to take approximately four to six weeks, subject to weather and operational conditions. Assay results are anticipated to be received progressively through Second Quarter 2026. RC drilling is a form of percussion drilling that uses high pressure air to flush rock chips up the centre of the drill rod for collection at surface in carefully controlled intervals representative of the depth of drilling. As drill chips travel up the centre of the RC drill rod, there is minimum sample contamination. Samples are split, logged and bagged for transport to Perth for laboratory assay. West Coast Silver is running multiple exploration programs from end of March to end of May 2026. With RC drilling having started, down-hole and surface geophysics are scheduled to commence at the end of March 2026. Diamond drilling to test the down-plunge extension of the Elizabeth Hill orebody commences in early April depending on drill rig availability. Focus through the next three months of exploration activities will be on processing, interpreting and reporting results, as well as dynamic repositioning of remaining planned drill holes to maximise chances of success from results received (geological, assay, geophysical).

West Coast Silver Limited Announces to Opens Elizabeth Hill Near Mine and Regional Silver Opportunities Alien Metals Limited announced that it has been amended by article 7 of the market ABUSE REGULATION (596/2014/EU) as the SAME has been amended by the market ABUSE (AMENDMENT) (EU EXIT). Drill hole 25WCAC026 intersected 4m @ 88g/t Ag from surface in weathered and chlorite-altered granite hosting quartz-carbonate veins (<1mm thick), and increasing silicification in the bottom of hole from 3.5-4m. The silver intersection is supported by 1m @ 1,635ppm Co from surface which is known to be associated with high-grade silver mineralisation at the Elizabth Hill Silver Mine. Silver intersections in drill holes 25WCAC025 and 25WCAC026 are 20m apart, demonstrating the continuity of the mineralisation corridor north of the Elizabeth Hill Silver Mine. Drill hole 25WCAC006 intersected 1m @ 26g/t Ag from1m (note the 0-1m sample was excluded due to possible surface contamination) in moderately chlorite altered granite. Silver intersections in drill holes25WCAC025 and 25WC AC026 Aircore Drill Holes 25WCAC017 to 25WCAC022 Very low-grade silver mineralisation above 5g/t Ag indicates slight silver enrichment distal to silver mineralisation. Aircore Drill H holes 25WCAC017 to 25 WCAC022 Aircore Drill Holes25WCAC017 to 25WC AC022 Aircore Drill H holes25WCAC017 to 25 WC AC022 Aircore DrillHoles 25WCAC017 to25WCAC022 Aircore Drill Toles 25WCAC007 to 25WCAC013 Mineralisation intersected in 25WCAC008 (0.5m @ 61g/t Ag from 8m), located 225m north of the Elizabeth Hill mine on the northern extension of the Munni Munni Fault, is important for demonstrating the potential to the north of the historical workings. Drill holes 25WCAC027 to 25WCAC029 did not contain significant intersections above 10g/t Ag. A mineralised intersection of 2m @ 39g/t Ag in 25WCAC071 is encouraging for the potential of the Elizabeth Hill South prospect, located 275m south of the Elizabeth Hill Silver Mine, where historical mineralisation such as 2m @ 1,550g/t Ag from 108m in AMEHRC012 and 1m @ 250g/t Ag from 118m in AG43. Drill holes 25WCAC037 to 25WCAC039, and 25WCAC072 contained less than 5g/t Ag. Announcement • Feb 06
