West Coast Silver Quarterly Activities Report

Alien Metals Limited (AIM: UFO), a minerals exploration and development company, notes that its joint venture partner, West Coast Silver Limited ("West Coast Silver") (ASX: WCE), has today released its Quarterly Activities Report for the period ended 30 June 2026. During the quarter, West Coast Silver continued to advance the Elizabeth Hill Silver Project ("Elizabeth Hill") in Western Australia, delivering a number of significant operational and technical milestones as it progresses the project towards resource growth and development.

Highlights:

·	Subsequent to quarter end, West Coast Silver reported high-grade diamond drill results and final reverse circulation (RC) percussion assays from the 2026 program, including 3 m at 524 g/t Ag from 183 m in 26WCDD029, with 1.5 m at 1,039 g/t Ag from 184.5 m, confirming a new high-grade silver zone beneath and south of the historical workings. Final RC assays also extended broad near-surface silver mineralisation outside the April 2026 MRE, including 44 m at 26 g/t Ag from surface in 26WCRC020 and 41 m at 23 g/t Ag from 1 m in 26WCRC019.
·	The new diamond intersection ties together historical high-grade silver intercepts to define an approximately 50 m long, north-south, sub-horizontal mineralised trend beneath and to the south of the historical mine workings, opening an important priority follow-up target at depth.
·	Inaugural Mineral Resource Estimate reported in accordance with the JORC Code (2012) ("MRE") and announced on 22 April 2026 comprising 141,000 tonnes at 617 g/t Ag for 2.795 Moz of contained silver above a 20 g/t Ag cut-off.
·	A 32-hole, 2,710 m RC drilling program was completed at Elizabeth Hill North in May 2026. Subsequent final assays confirmed broad near-surface silver mineralisation extending north and west of the April 2026 MRE, with multiple holes ending in mineralisation and increasing the scale of the Elizabeth Hill system.
·	Key RC intersections included: 60 m at 25 g/t Ag from surface in 26WCRC004, 28 m at 29 g/t Ag from 2 m in 26WCRC002, 9 m at 33 g/t Ag from 6 m in 26WCRC003, 2 m at 96 g/t Ag from 91 m in 26WCRC012 and 1 m at 157 g/t Ag from surface in 26WCRC011. Final RC assays included 44 m at 26 g/t Ag from surface in 26WCRC020, 41 m at 23 g/t Ag from 1 m in 26WCRC019 and 12 m at 15 g/t Ag from 31 m in 26WCRC025, with 26WCRC019 and 26WCRC025 ending in mineralisation.
·	Diamond drilling commenced during the Quarter and was nearing completion at quarter end, targeting down-dip and down-plunge extensions beneath the historical mine, infill within the reported MRE block model and follow-up of RC holes that ended in mineralisation.
·	26WCDD029 also intersected massive sulphides returning 0.45 m at 2.73% Ni, 0.93% Cu and 0.7 g/t Pd from 154.87 m, opening the possibility of an additional nickel-copper-palladium mineralisation style at Elizabeth Hill.
·	West Coast Silver announced a Growth & Development Plan focused on resource growth, conversion of JORC (2012) Inferred Resources to Indicated Resources, metallurgical testwork, mine-study inputs and staged economic evaluation.
·	West Coast Silver finished planning and organisation of an extensive district-scale IP and CSAMT geophysical survey program over an approximately 4 km length of the Munni Munni Fault Zone, supported by a $114,312 WA Government Exploration Incentive Scheme co-funded geophysics grant covering 50% of the ground geophysical program.
·	Planning and budgeting for potential H2 drill testing of the Elizabeth Hill South target was completed. Proposed exploration aims to follow-up 2025 aircore drilling which intersected 2m at 39g/t Ag from 12m (25WCAC071); results from historical hole AMEHRC012 which recorded 2 m at 1,550 g/t Ag from 108m; and a re-evaluation of historical and third-party drilling in the area.
·	A specialist review by David Lewis B.Sc. (Geological Sciences), M.Sc. (Geology), P.Geo. (PGO) (Structural Geologist) identified geological similarities between Elizabeth Hill and global 5-element silver system styles of mineralisation, which supports broader district-scale exploration across West Coast Silver's approximately 180 km² project area.
·	Cash balance of approximately A$3.0 million at 30 June 2026.

Alien holds a 30% interest in Elizabeth Hill and holds 30.5 million shares in West Coast Silver (representing an approximate 8.7% interest in the issued share capital of West Coast Silver).

Notes to Editors

Alien Metals Ltd is a mining exploration and development company quoted on the AIM market of the London Stock Exchange (AIM: UFO). The Company follows a balanced strategy focused on advancing and strengthening its asset portfolio through targeted technical work and project development, while evaluating partnerships, joint ventures, and selective monetisation opportunities to enhance shareholder value. At the same time, Alien will continue to consider opportunities to expand its asset base through carefully selected acquisition opportunities consistent with the Board's disciplined investment criteria.

Alien's 100%-owned Georgina Basin IOCG Project comprises a tenement package of approximately 2,500 km² in the East Tennant province of the Northern Territory. Exploration by the Project's former owners has confirmed the IOCG potential of the tenement package, with the identification of elevated IOCG pathfinder elements, including copper, bismuth, silver and uranium, in drilling, and three drill-ready gravity anomalies remain to be adequately tested.

Alien's principal iron ore focus is the advancement and development of its 90%-owned Hancock Iron Ore Project in the central Pilbara region of Western Australia. The Hancock tenements contain a JORC-compliant resource of 8.4Mt at 60% Fe and offer significant exploration upside, which is targeted to deliver a mining operation of 2Mtpa for 10 years. The Project benefits from direct access to the Great Northern Highway, providing a route to export facilities at Port Hedland, one of the world's largest iron ore export hubs. Alien also holds exploration interests in the Brockman and Vivash iron ore projects in the West Pilbara.

Alien additionally retains exposure to two advanced precious and base metal assets in the Pilbara. At Munni Munni, one of Australia's largest PGM systems hosting a historic resource of 2.2Moz PGM (palladium, platinum, and rhodium) and gold, the Company has completed its partial asset sale and joint venture transaction with GreenTech Metals Ltd under which Alien retains a 30% interest, free carried to completion of a bankable feasibility study at Munni Munni, and additionally holds 37.9 million shares in GreenTech Metals Ltd. Alien (via a wholly owned subsidiary) also retains a 30% interest in the Elizabeth Hill Silver Project through a joint venture with Crest, which encompasses the Elizabeth Hill Mining Lease M47/342, which has produced some of Australia's highest-grade silver ore during the late 1990s. Alien retains a 30% interest in the Elizabeth Hill Silver Project and additionally holds 30.5 million shares in West Coast Silver Limited, providing both direct project exposure and equity participation in ongoing development.
