GreenTech Intersects High-Grade Copper at Whundo Project

4.76m at 7.13% Copper, Including 3.44m at 9.43% Copper

Alien Metals Limited (AIM: UFO), a minerals exploration and development company, announces that GreenTech Metals Limited ("GreenTech") (ASX: GRE), in which Alien holds approximately 10% of the issued share capital, has today reported exceptional high-grade copper-gold-silver-zinc assay results from diamond drilling at the Ayshia deposit within GreenTech's 100%-owned Whundo Cu-Zn-Au Project in the West Pilbara, Western Australia.

Highlights:

·	Diamond drilling at the Ayshia deposit within the Whundo Project has returned high-grade copper-gold-silver:
	- 4.76m @ 7.13% Cu, 1.20% Zn, 0.88 g/t Au and 29.6 g/t Ag from 367m, incl.
	- 3.44m @ 9.43% Cu, 1.59% Zn, 1.20 g/t Au and 39.7 g/t Ag from 367.62m (26GTDD016)
·	New drill hole provides down plunge extension to recent and historical1 drilling at Ayshia, including:
	- 23.7m @ 3.19% Cu and 0.39% Zn from 209m (12AYDD103)
	- 13.97m @ 3.4% Cu and 0.42% Zn from 243.63m (12AYDD109)
	- 20m @ 0.60% Cu, 1% Zn and 0.11 g/t Au from 250 m, incl.
	- 3m @ 3.1% Cu and 2.6% Zn from 261m (24GTRC004)
·	The 4.76 m intersection grading 7.13% Cu, including 3.44 m at 9.43% Cu (see photo 1), represents the highest-average-grade multi-metre copper intersection identified at Ayshia to date and ranks among the highest-grade copper intersections recorded across the broader Whundo Project.
·	The exploration program continues to demonstrate potential for expansion of current Whundo JORC 2012 Mineral Resource2 of 6.2 Mt @ 1.12% Cu, 1.04% Zn, with significant gold and silver intercepts to be assessed as part of an updated Mineral Resource estimate targeted for Q4 2026.
·	Alien holds 37.9 million GreenTech shares, representing approximately 10% of GreenTech's issued share capital and providing Alien shareholders with exposure to the Whundo Project.
·	Alien retains a 30% interest in Munni Munni, free carried to completion of a bankable feasibility study. GreenTech is working to validate the historical non-JORC estimate of 24 Mt at 2.9 g/t 4E (approximately 2.2 Moz contained 4E) and establish a JORC 2012 Mineral Resource.

Vince Fayad, Executive Director of Alien Metals, commented:

"These are exceptional drilling results. The intersection of 4.76 metres at 7.13% copper, including 3.44 metres at 9.43% copper, highlights the high-grade potential of GreenTech's Whundo Project. Alien shareholders retain exposure to continued exploration success through the Company's approximately 10% equity interest in GreenTech. With Whundo adjacent to Munni Munni, where Alien retains a 30% interest free carried through to completion of a bankable feasibility study, Alien is well positioned to benefit as GreenTech advances both projects."

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.
