Diamond Drilling for High-Grade Silver Extensions Below the Elizabeth Hill Mine Commences
Alien Metals Limited (AIM: UFO), a minerals exploration and development company, is pleased to advise that its joint venture partner, West Coast Silver Limited (ASX: WCE) ("West Coast" or "West Coast Silver"), has 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 Q2 2026.

Notes to Editors
Alien Metals Ltd is a mining exploration and development company listed on the AIM market of the London Stock Exchange (AIM: UFO). The Company follows a balanced strategy of advancing and strengthening its asset portfolio through targeted technical work and project development, while evaluating partnerships, joint ventures, and selective monetisation opportunities that are value-enhancing for shareholders. At the same time, Alien will continue to consider opportunities to expand our asset base through carefully selected acquisition opportunities which meet the Board's prudent criteria.
Alien's principal focus is the advancement and development of its 90%-owned Hancock Iron Ore Project in the central Pilbara region of Western Australia. The Hancock tenements contain a JORC-compliant resource of 8.4Mt at 60% Fe and offer significant exploration upside, which is targeted to deliver a mining operation of 2Mtpa for 10 years. The Project benefits from direct access to the Great Northern Highway, providing a route to export facilities at Port Hedland, one of the world's largest iron ore export hubs. Alien also holds exploration interests in the Brockman and Vivash iron ore projects in the West Pilbara.
Alien additionally retains exposure to two advanced precious and base metal assets in the Pilbara. At Munni Munni, one of Australia's largest PGM systems hosting a historic resource of 2.2Moz PGM (Palladium, Platinum, and Rhodium) and gold, the Company has completed its partial asset sale and joint venture transaction with GreenTech Metals Ltd, under which Alien has divested a 70% interest in the Munni Munni tenements to GreenTech and Alien will retain a 30% interest, free carried to the completion of a bankable feasibility study at Munni Munni. Alien (via wholly owned subsidiary A.C.N. 643 478 371 Pty Ltd) also retains a 30% interest in the Elizabeth Hill Silver Project through a joint venture with Crest, which encompasses the Elizabeth Hill Mining Lease M47/342, which has produced some of Australia's highest-grade silver ore during the late 1990s.
Competent Person's Statement
The information in this announcement that relates to Exploration Results is based on information reviewed by Mr Max Nind who is a Member of the Australian Institute of Geoscientists. Mr Nind is a consultant to Alien and a full-time employee of ERM Australia Consultants Pty Ltd.
Mr Nind has sufficient experience that is relevant to the style of mineralisation and type of deposits under consideration, and to the activity being undertaken to qualify as a Competent Person as defined in the 2012 Edition of the Joint Ore Reserves Committee (JORC) 'Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves', and a Specialist under the VALMIN Code 2015 Edition of the 'Australasian Code for Public Reporting of Technical Assessments and Valuations of Mineral Assets'. Mr Nind consents to the inclusion in the announcement of the matters based on this information and in the form and context in which it appears.
Appendix A - ASX: WCE ANNOUNCEMENT
Diamond Drilling for High-Grade Silver Extensions Below the Elizabeth Hill Mine Commences
· A diamond drilling program of up to 1,500 meters (6 holes) has commenced beneath the historical Elizabeth Hill silver mine in Pilbara, Western Australia.
· This is the first thorough test of deeper silver mineralisation along the Munni Munni Fault, which is the main feature controlling high-grade silver distribution at Elizabeth Hill.
· The drilling will target areas directly below and next to the underground mine, where drilling in 2025 showed that silver extends to the surface.
· All holes are planned to reach the Munni Munni Fault within 200 meters of the surface.
· Drilling should take about four to six weeks. Results are expected to start coming in during the second quarter of 2026.
West Coast Silver Limited (ASX: WCE) ('West Coast Silver' or the 'Company') is pleased to announce 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 (Figure 1 and Figure 2).
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 Q2 2026.
Commenting on the results, Executive Chairman Bruce Garlick said:
"Our previous 2025 drilling confirmed that silver mineralisation at Elizabeth Hill extends beyond the historical underground mine and associated with a broader structural corridor along the Munni Munni Fault. This current program of diamond drilling below Elizabeth Hill is designed to determine whether there are high-grade silver extensions below and south of the mine. The drilling will also test whether high-grade mineralisation repeats at depth; a model that, if confirmed, could materially expand the resource potential."
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)

The Elizabeth Hill Project
Elizabeth Hill is historically one of Australia's highest grade silver projects and has a proven production history. Key points are outlined below:
· 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)[1].
· Mining operations ceased in 2000 as a result of low silver prices (US $5)[2].
· 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.
