Shallow High-Grade Silver Mineralisation Intersected 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) (formerly Errawarra Resources Limited) ("West Coast Silver"), has announced shallow, high-grade silver mineralisation from the first two diamond drill holes of its inaugural drilling campaign 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 Alien's joint venture partner, West Coast Silver.
Highlights:
· Hole 25WCDD001 intersected:
o 5m at 313g/t Silver (Ag) from 20m; and
o 5m at 2822g/t Ag from 26m; including
§ 2m at 6951g/t Ag from 27m
· Hole 25WWCDD002 intersected 12m at 153g/t Ag from surface; including
o 1m at 973g/t Ag from 1m
· Silver mineralisation starts at surface in both holes (Appendix B - pXRF Results[1])
· Drill holes were strategically designed to test high-grade, shallow silver targets.
· Half-core samples dispatched to laboratory for assay; results expected in 6-8 weeks. High grade nature of the samples necessitates more comprehensive laboratory analysis.
· Systematic core logging underway to improve understanding of structural and lithological controls.
Robert Mosig, Technical Director, commented:
"These initial results from the Elizabeth Hill JV are highly encouraging. The intersection of exceptionally high-grade silver mineralisation from surface, particularly in the first hole, supports the historic production profile and confirms the potential for significant near-surface mineralisation. We look forward to the next phase of drilling and receipt of laboratory assays to further advance this high-grade project."
Cautionary Statement
pXRF results should not be considered a proxy for quantitative laboratory analyses, which are required to determine the actual abundance and grade of the mineralisation. The mineralised core intervals referenced in this announcement have been appropriately and systematically sampled and dispatched to ALS Global Laboratories for quantitative analysis, the results of which will be reported once results are received.
High-grade silver intersected in core from the first two drill holes, 25WCDD001 and 25WCDD002, based on portable XRF (pXRF) readings[2]. Both holes intersected mineralisation from surface, with particularly impressive results from hole 25WCDD001, which intersected:
· 5m at 313g/t Ag (10oz/t) from 20m; and
· 5m at 2822g/t Ag (90.7oz/t) from 26m; including
o 2m @ 6951g/t Ag (223.5oz/t) from 27m.
Hole 25WWCDD002 intersected
· 12m at 153g/t Ag (4.9oz/t) from surface; including
o 1m at 973g/t Ag (31.3oz/t) from 2m
These initial holes were strategically selected to test the potential for shallow, high-grade mineralisation.
Anomalous Lead, Zinc and Copper values have also been returned, and further analysis will be carried out during the inaugural drill program to quantify the presence of these elements and their impact on project economics. Refer to Appendix B - pXRF Results for full results of other elements.

Geological Interpretation
Drill core from both holes has been systematically logged, with particular attention being paid to structural and lithological features to improve the geological understanding of the silver mineralisation.
Previous drilling at Elizabeth Hill intersected a high-grade silver vein network with an associated poly-metallic mineralised halo which includes copper, lead and zinc hosted in chalcopyrite, galena, arsenopyrite and sphalerite. In addition to pervasive malachite observed in the core of the hydrothermal vein system.
Core recovery has been in excess of 95%, and successful core orientation has allowed detailed structural measurements of the near-surface mineralisation. Furthermore, holes 25WCDD001 and 25WWCDD002 have traversed a sparsely drilled section of the deposit, highlighting previously unidentified structural trends. The information gathered from these holes provides valuable information, which will enable key decisions to be made for the remainder of the drill program.
Laboratory Testing
The core has been cut, and half-core samples have been sent for confirmatory laboratory assays, which are expected to be returned within 6-8 weeks.
An analysis of pXRF v assay results will be carried out when results are received to demonstrate any variances between pXRF results and laboratory analysis.
The diamond drill program continues at Elizabeth Hill, with further holes planned to test down-plunge and extensional targets.
Regional Exploration Update
Regional fieldworks, including soil sampling, have recently concluded, with all samples being sent to the laboratory for assessment. Lab results are being received progressively, with a consolidated model being built to define next steps.
An updated Programme of Works (PoW) has recently been approved by DEMIRS (Department of Energy, Mines, Industry Regulation and Safety) to facilitate additional field exploration work, including trenching on near mine and regional targets.

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)[4]
· Previous mining operation ceased abruptly in 2000 because of low silver prices (US$5/oz)[5] 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.
