Significant Silver Assays from Fieldwork at Elizabeth Hill 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) (formerly Errawarra Resources Limited), has announced significant assay results from recent float and rock chip sampling 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 WCE.

Highlights:

·    Silver assays of up to 490 g/t Ag returned from float and rock chip sampling.

·    Multiple samples returned elevated copper (up to 0.42% Cu) and gold (up to 0.19 g/t Au).

·    Silver-rich float samples have been identified up to ~ 500m north and   ~ 200m south of the historic Elizabeth Hill high-grade silver mine, indicating potential for new mineralised zones.

·    Follow-up trenching and sampling works have commenced on site.

·    A comprehensive near-mine and regional exploration targeting study is nearing completion.

Robert Mosig, Technical Director, commented:

"These latest assay results continue to validate the outstanding exploration potential at Elizabeth Hill. The scale and tenor of the silver mineralisation identified in areas away from the historic mine suggest the possibility of multiple new mineralised systems within the broader project area. With trenching now underway and a follow-up drill programme in planning, we are excited to see this momentum continue as our joint venture partner advances the project. "

The sampling program involved the collection of 115 rock chip samples, with assay results confirming anomalous silver, copper, and gold mineralisation in areas both north and south of the historic Elizabeth Hill high-grade silver mine. Notable assay results from the complete results, which are detailed in Appendix A of the announcement include:

·    25EW06-062: 490 g/t Ag, 0.03 g/t Au, 0.17% Cu

·    25EW06-057: 316 g/t Ag, 0.19 g/t Au, 0.11% Cu

·    25EW06-063: 276 g/t Ag, 0.13 g/t Au, 0.14% Cu

·    25EW06-025: 179 g/t Ag, 0.42% Cu

·    25EW06-064: 178 g/t Ag, 0.1% Cu

Figure 1 - Location of float sample assay results north and south of the historic Elizabeth high grade silver mine

These significant assay results-up to 490 g/t Ag, 0.19 g/t Au, and 0.42% Cu-occur in two key areas relative to the historic high-grade silver mine. A cluster of samples grading >100 g/t Ag are located over an area 200-500m north of the mine, while an isolated sample (170 g/t Ag) lies ~200 m to the south. The results suggest potential for additional new mineralised source areas and are possibly related to the north-south trending Munni Munni fault system.

Upcoming Works

Following on from the completion of its inaugural drilling campaign and building on its significant results, including 21 metres at 1,047g/t Ag from 10 metres in 25WCDD001, West Coast Silver has now commenced a systematic approach to further exploring Elizabeth Hill and the surrounding areas.

This includes:

·    Trenching, mapping, and additional rock chip sampling, which has already commenced at site;

·    Completion of near mine and regional targeting works, including prioritisation of targets (estimated completion 3-4 weeks); and

·    Development of follow-on drill campaigns to the inaugural campaign, including consideration for air core, reverse circulation and additional diamond drilling.

Elizabeth Hill Silver Project Overview

Elizabeth Hill, one of Australia's highest-grade silver projects, has a proven production history outlined below:

·    High grades enable 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) [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

·    Simplistic historical processing technique: native silver was recovered via low-cost gravity separation due to high grades and large silver nugget sizing

·    Significant untapped potential remains in and around the historic mine site, with limited, outdated drilling and geophysics deployed

·    Tier-1 mining jurisdiction - located on a mining lease with processing facilities adjacent at the nearby Radio Hill

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 it 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 explora5on tenements surrounding the historical silver mine which has produced some of Australia's highest-grade silver ore during the late 1990s.
