Elizabeth Hill high-grade silver discovery

Alien Metals Limited (AIM: UFO), a minerals exploration and development company, notes the release of an announcement from its joint venture partner at the Elizabeth Hill Silver Project ("Elizabeth Hill"), West Coast Silver Limited ("West Coast Silver") (ASX: WCE). The announcement outlines results from diamond drilling with high-grade silver and base metal intersections. West Coast Silver has also received significant assay results for the last 15 of 32 reverse circulation (RC) drill holes completed in May 2026 at the Elizabeth Hill Project, located near Karratha in the Pilbara region of Western Australia.

Key Highlights:

·	Recently returned diamond drilling (DD) assays from below and south of the Elizabeth Hill historical silver workings have intersected:
	- 3m @ 524g/t Ag from 183m; including 1.5m @ 1,039g/t Ag from 184.5m in diamond drill hole 26WCDD029.
·	This diamond drill hole confirms a new, still to be fully defined, discrete zone of silver mineralisation, below and separate from the previously mined Elizabeth Hill orebody.
·	The new drill intersection ties together historical drill intersections of 7m @ 607g/t Ag from 57m (including 2m @ 1,995g/t Ag from 61m) in underground drill hole UGD084 ; and 4m @ 223g/t Ag from 190m in surface drill hole AG33, to define an approximately 50m long, north-south, sub-horizontal, mineralised trend beneath and to the south of historical mine workings.
·	Massive sulphides were also intersected in hole 26WCDD029, which targeted an off-hole electromagnetic (EM) conductor from 25WCDD025 returning:
	- 2.73% Ni, 0.93% Cu and 0.7g/t Pd over 0.45m from a depth of 154.87m down hole.
·	Final assays from 2026 RC extension drilling continued to increase the scale of silver mineralisation north and west of the Elizabeth Hill maiden MRE (April 2026).
·	Best RC intersections received include:
	- 44m @ 26g/t Ag from surface (including 31m 30g/t Ag from 3m) in 26WCRC020.
	- 41m @ 23g/t Ag from 1m and ending in mineralisation in 26WCRC019.
	- 12m @ 15g/t Ag from 31m ending in mineralisation in 26WCRC025.
·	Reverse circulation (RC) drill hole assays have extended a broad near-surface mineralisation zone outside of the Elizabeth Hill mineral resource estimate (MRE) reported in April 2026.
·	Exploration diamond drilling at Elizabeth Hill is progressing through the final planned holes, with further assays expected to be progressively reported through July and August.

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).

Alien's principal 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.
