Mobilisation Commences for Inaugural Drilling

Mobilisation Commences for Inaugural Drilling Campaign at Elizabeth Hill Silver Project

Alien Metals Ltd (AIM: UFO), a minerals exploration and development company, is pleased to announce that its joint venture partner, West Coast Silver Limited (ASX: WCE) (formerly Errawarra Resources Limited) ("West Coast Silver"), has commenced mobilisation for its maiden diamond drilling campaign at the Elizabeth Hill Silver Project ("Elizabeth Hill" or the "Project"), located in the Pilbara region of Western Australia.

Highlights:

• Mobilisation of drilling contractor West Core Drilling Pty Ltd scheduled over the weekend of 24-25 May 2025
• Drilling operations to commence shortly thereafter, targeting extensions to known high-grade silver mineralisation
• Programme to target extensional and down-plunge silver mineralisation, with a focus on expanding known high-grade zones
• Use of portable XRF ('pXRF') technology on site to provide real-time elemental data and guide in-field decision-making
• First significant drill program at Elizabeth Hill under the West Coast Silver joint venture

The West Coast Silver technical team has also been finalising preparations, both on-site and at the Company's core logging and processing facility in Karratha, to ensure an efficient and well-supported start to the programme.

The upcoming drilling campaign will test both extensional and down-plunge targets associated with the known high-grade silver mineralisation at Elizabeth Hill. In addition to targeting potential mineralised extensions, the programme aims to enhance geological understanding of the structural framework that hosts the Elizabeth Hill mineralised envelope.

To support real-time decision-making and optimise drill targeting, portable X-Ray Fluorescence (pXRF) technology will be utilised on site to deliver rapid elemental analysis during the course of the programme.

Guy Robertson, Executive Chairman, commented:

"Commencement of drilling at Elizabeth Hill marks another major step forward for the joint venture. With our partners at West Coast Silver now on the ground and mobilising to drill, we look forward to results from what is one of Australia's highest-grade historic silver mines. This work aligns with our strategy to progress the Elizabeth Hill and Pinderi Hills projects with minimal dilution to Alien shareholders while retaining exposure to significant upside."

Elizabeth Hill Silver Project Overview

• High grades enable low processing tonnes: 1.2Moz of silver was produced from just 16,830t of ore at ahead grade of 2,194g/t (77.4 oz/t Ag)1
• Previous mining operation ceased abruptly in 2000 because of low silver prices (US$5/oz)2 and a dispute between previous joint venture parties
