Phase 2 Drilling Has Commenced at Elizabeth Hill

Phase 2 Drilling Has Commenced at Elizabeth Hill Silver Project

Alien Metals Limited (AIM: UFO), a minerals exploration and development company, is pleased to report that its joint venture partner, West Coast Silver Limited (ASX: WCE) ("West Coast Silver") has announced that Phase 2 diamond drilling has commenced at the Elizabeth Hill Silver Project ("Elizabeth Hill" or the "Project") in the Pilbara region of Western Australia. The Project, in which Alien retains a 30% free-carried interest through to a decision to mine, is operated by West Coast Silver.

Belinda Murray, Executive Director of Alien, commented:

"It's great to see our joint venture partner, West Coast Silver, progressing rapidly with the next phase of drilling at Elizabeth Hill. The commencement of this program marks another important step in unlocking the full potential of one of Australia's highest-grade historical silver projects. We look forward to the results from this campaign as the project continues to build strong momentum under the West Coast Silver team."

Phase 2 Drilling Has Commenced at Elizabeth Hill

Highlights

• Phase 2 diamond drilling commenced on 11 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 at depth below historical workings
• Transient Electromagnetic (TEM) and drone magnetic surveys have been completed, and teams demobilised
• Geophysical processing commencing and due in the next 1-2 weeks to refine targets along the Munni Munni Fault and parallel structures

West Coast Silver Limited (ASX: WCE) (West Coast Silver or the Company) is pleased to advise that the second phase of diamond drilling commenced on the 11th October 2025, at the high-grade Elizabeth Hill Silver Project in the Pilbara region of Western Australia (Elizabeth Hill) (Figure 4, Figure 6).

The program marks the next phase of West Coast Silver's strategy that has a dual focus: (1) to confirm and define the shallow, very high-grade silver immediately adjacent to the historical workings; and (2) to test for a potential deeper continuation to the south (Figure 4, Figure 5).

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 (Figure 1, Figure 2, Figure 3).

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.

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 high-conviction deeper target that could represent a down-plunge repeat of the Elizabeth Hill system."

Deeper Exploration Prospects

A review of historical drilling and geochemical data supports the potential for a deeper extension of the Elizabeth Hill Mine sequence (Figure 4, Figure 5).

Underground diamond drill hole UGD084 intersected 2m @ 1,995g/t Ag from 61m within an interval of 6m @ 705g/t Ag from 57m down hole. 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 massive nickel sulphides with 1m @ 23,304ppm Ni, 6,013ppm Cu, 1,078ppm Pb, 4,104 ppm Zn and 50ppm Ag from 52m down hole. 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, previously reported, provide confidence in targeting the down plunge extension of the Elizabeth Hill mineralisation.

The Elizabeth Hill Project

Elizabeth Hill, a 70/30 joint venture between West Coast Silver (ASX: WCE) and Alien Metals (AIM: UFO) is one of Australia's high-grade silver projects and has a proven production history outlined below:

• Previous mining operation ceased in 2000: because of low silver prices (US$5)[3].
• Tier 1 Mining Jurisdiction located on a mining lease with potential processing option at the nearby Radio Hill site.

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.
