·	West Core Drilling is scheduled to mobilise in the week of 5 October, with drilling expected to continue through early to mid-December.
·	The four workstreams are: 1. MRE development drilling will target selected lower confidence areas above historic mine workings to support potential reclassification of Inferred Mineral Resources to Indicated status, and are intended to inform future evaluation of ore reserves. 2. Western extension drilling will test broad silver mineralisation outside the current 2.8Moz silver MRE block model1. 3. Elizabeth Hill Deeps drilling will test the continuity of a new high-grade silver zone that remains open to the east and south below historic mine workings2. 4. Underground extension drilling will test inadequately drilled areas immediately down plunge of Elizabeth Hill’s deepest historic mine workings.
·	Drill core will be geotechnically, metallurgically and structurally logged, and sampled as part of Scoping Study test works.
·	The program has been designed using 2025-2026 drilling outcomes and resultant updated structural and geological interpretations.
·	New drilling results will be included in a March 2027 MRE update and Q1 2027 Scoping Study outcomes. A separate MRE update remains scheduled for November 2026.

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 West Coast Silver, 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.
