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's focus is on delivering a profitable direct shipping iron ore operation from its 90% Hancock iron ore project in the central Pilbara region of Western Australia. The Hancock tenements currently contain a JORC-compliant resource of 8.4Mt iron ore @ 60% Fe and offers significant exploration upside which is targeted to deliver a mining operation of 2Mtpa for 10 years.

These Hancock Project tenements have direct access to the Great Northern Highway, which provides an essential export route to export facilities at Port Hedland, from where more than 500Mt of iron ore is exported annually (30% of global production). The Company also has an interest in two iron ore exploration projects Brockman and Vivash, located in the West Pilbara.

The Company owns one of Australia's largest PGM deposits, Munni Munni which hosts a deposit containing a historic resource of 2.2Moz PGM (Palladium, Platinum, and Rhodium) and Gold. The Company has recently entered into a joint venture with West Coast Silver Limited (formerly Errawarra Resources Limited) for the development of the Elizabeth Hill Silver Project, located near Karratha in the Pilbara, which consists of the Elizabeth Hill Mining Lease and exploration tenements surrounding the historical silver mine which has produced some of Australia's highest-grade silver ore during the late 1990s.

Appendix A - ASX:WCE ANNOUNCEMENT

Accelerated Phase 2 Drilling campaign commences at Elizabeth Hill

Highlights

·    Phase 2 diamond drilling to commence on 10 October 2025 at the high-grade Elizabeth Hill Silver Project (Pilbara, WA)

·    Follows multiple bonanza-grade intercepts from Phase 1 (Aug-Sep 2025)

·    Program aims to test near-surface high-grade mineralisation, and prospective areas down plunge of the historical workings with mineralisation open at depth

·    Additional ~3,000m air core program scheduled to begin early November, targeting near-mine anomalies defined by recent geophysics

·    Geophysics in progress: Transient Electromagnetic (TEM) and drone magnetic surveys continuing to refine targets along the Munni Munni Fault and parallel structures

·    Drilling Contractor and WCE personnel have commenced mobilisation activities to site

West Coast Silver Limited (ASX: WCE) (West Coast Silver or the Company) is pleased to advise that the second phase of diamond drilling will commence ahead of schedule, on 10 October 2025, at the high-grade Elizabeth Hill Silver Project in the Pilbara region of Western Australia (Elizabeth Hill) (Figure 1, Figure 2, Figure 6).

The program has a dual focus: (1) to confirm and define the shallow, very high-grade silver immediately adjacent to the historic workings; and (2) to test a potential for deeper continuation to the south where the mineralisation remains open at depth.

The Phase 2 drilling program will consist of approximately 14 diamond drill holes (~1,300 metres). This will be expanded as required based on the success of the program. Drilling will be undertaken by Wallis Drilling Pty Ltd.

In addition, geophysical surveys have commenced to provide additional high-quality data for refinement of the proposed air core programs commencing in November (Figure 3, Figure 4, Figure 5).

Commenting, Executive Chairman Bruce Garlick said:

"We're back on the ground and moving quickly to build on the outstanding grades from our initial campaign. Phase 2 is designed to do two things: demonstrate near-surface continuity in the oxide zone and test a deeper target that could represent a down-plunge repeat of the Elizabeth Hill system.

Down Plunge Exploration Targets

Further evaluation of historical underground and surface drilling geology logs and geochemistry has reinforced the prospectivity of the down plunge target as a potential extension of the Elizabeth Hill Mine sequence (Figure 2).

Underground diamond drill hole UGD084 intersected 2m @ 1,995g/t Ag within an interval of 6m @ 705g/t Ag (Figure 1 ,Figure 2, Appendices 1-2). Drill logs at the time also describe native silver mineralisation within the 2m high grade interval, similar to that recorded in the Elizabeth Hill Deposit (WAMEX Report A62365).

Underground diamond drill hole UGD085 intersected 23,304 ppm Ni, 6,013 ppm Cu, 1,078 ppm Pb, 4,104 ppm Zn and 50 ppm Ag (Figure 1, Figure 2). The drill log describes complex textures with calcite brecciation reflecting similar geology to the Elizabeth Hill mine sequence (WAMEX Report A62365).

These drill holes combined with drill hole AG33 (Figure 1, Figure 2) previously reported, provide confidence in targeting the down plunge extension of the Elizabeth Hill mineralisation.

Geophysical Programs

Drone magnetic and Loupe TEM programs are currently being conducted on site. The Drone Magnetic survey is being flown at 20m line spacing to refine the targeting for planned air core programs, as well as defining further potential Elizabeth Hill style targets on the Munni Munni fault (Figure 3, Figure 4).

The Loupe TEM survey is being undertaken to test for near surface conductors that may support targeting along the Munni Munni fault, as well as other prospective structures (Figure 5).

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)[2].

·    Previous mining operation ceased in 2000: because of low silver prices (US$5)[3].

·    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 offers 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 6: 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.

The upcoming Phase 2 program represents the next step in defining near-surface continuity and testing deeper repeat potential within this proven high-grade system.
