Alien Metals Limited Announces New Exploration Targets Across Elizabeth Hill Silver Project
Alien Metals Limited, a minerals exploration and development company, has advised that its joint venture partner, West Coast Silver Limited ("West Coast" or "West Coast Silver"), has announced the results of a detailed drone magnetic survey completed at the Elizabeth Hill Silver Project near Karratha, in the Pilbara region of Western Australia. The results delivered by West Coast Silver mark a very important step forward for the Elizabeth Hill Project. The high-resolution drone magnetic survey has not only refined our understanding of the structural controls at the historical mine but has also highlighted a series of new targets that point to a much larger mineralised system than previously demonstrated. The identification of multiple structural targets, particularly those located close to the original workings and supported by surface sampling and drilling, reinforces our view that Elizabeth Hill retains significant untapped potential. As West Coast advances its 2026 exploration programme, Alien remains confident that continued integration of geophysics, geochemistry, and drilling will unlock further value across the broader tenement package. The scale of the structures identified, including new trends beyond the Munni Munni fault, underscores the opportunity for repeat, high-grade silver mineralisation within the joint venture area. A high-resolution drone magnetic survey was completed in Fourth Quarter 2025 covering ~14 km2 of the main Elizabeth Hill mineralised trend. The aim of the geophysical survey was to map out structures across the Elizabeth Hill prospect e.g. faults, that could be trap sites for potential silver mineralisation. The drone magnetic survey identified multiple new targets for mineralisation testing along known (Munni Munni fault) and new structural trends. Key structures defined by the drone survey were coincident with anomalous surface and near-surface assays from field sampling and aircore drilling. Twenty (20) structural targets are defined at the intersection of interpreted fault structures having the potential to localise silver mineralisation. Eight (8) of twenty structural targets are located within 1.2 km of the historical Elizabeth Hill silver mine. Proximity of geophysical targets to Elizabeth Hill mine and overlap with significant surface sampling and aircore drilling assays, confirms near-mine growth potential and importance of structures in mineralisation localisation. The Munni Munni fault is confirmed as a key mineralised structure over a length of 6.8 km, with mineralisation discovered (aircore and surface assays) coincident with the fault north and south of Elizabeth Hill silver mine. Drone magnetics defined structural targets are not limited to the Munni Munni fault, with the eastern margin of the Munni Munni intrusion identified as a new potential structural setting for silver and critical metals occurrences. The survey has highlighted multiple new exploration target areas, and the potential for a larger-scale silver-bearing mineralised system beyond the historical high-grade Elizabeth Hill mine. The results from WCE's detailed drone magnetic survey confirm structures controlling silver mineralisation at Elizabeth Hill extending well beyond the historical mine workings. The results when overlain with previously reported anomalous surface sampling and aircore drilling assays show a pattern of new targets along the Munni Munni fault north and south of Elizabeth Hill, and significantly in new locations not along the Munni Munni fault. The identification of multiple fault jogs and structural intersections, with eight of the twenty targets located proximal to the Elizabeth Hill mine, reinforces our view that the Elizabeth Hill deposit is unlikely to be a standalone occurrence. Elizabeth Hill is potentially part of a broader, repeatable silver mineralised system. Testing the near mine and regional potential for mineralisation is part of WCE's planned 2026 exploration scope of works. A detailed drone magnetic survey, covering ~14 km2 of WCE tenement holding and centred on the north-south trending Munni Munni fault, was designed to refine the structural architecture controlling silver mineralisation at Elizabeth Hill for application in identifying new regional target areas (refer to ASX Announcement dated 13 November 2025 for JORC Table with drone magnetic survey details). A drone magnetic survey uses a drone fitted with a sensitive magnetometer to measure small variations in the Earth's magnetic field across the project area. These variations reflect differences in rock types and structures beneath the surface, allowing geologists to map faults, contacts and geological features that may control mineralisation. Because the drone flies low with closer line spacing, it is able to capture much higher-resolution data than older regional airborne surveys, helping identify smaller structural features that could potentially host silver mineralisation. The high-resolution drone magnetic survey successfully resolved fault flexures, splays and intersections that were not clearly defined from earlier regional, wider spaced, magnetic surveys. Structural analysis has interpreted 20 discrete target zones with potentially silver-favourable mineralisation traps at fault bends and intersections between the Munni Munni fault and secondary structures. Some of these new magnetic targets are supported by anomalous surface geochemistry and aircore drilling (refer to ASX Announcement dated 24 February 2026), providing greater confidence in the interpretations. Eight targets are located within 1.2 km of the historical Elizabeth Hill silver mine, with six targets aligned south along the Munni Munni fault in a "Pearls-On-a-String" style. These six targets are potentially in similar structural settings to, and repetitions of, that hosting the Elizabeth Hill silver deposit. The interpretation also highlights the eastern margin of the Munni Munni intrusion, as a secondary target corridor.
