Geochemical Review Confirms Munni Munni Targets

Alien Metals Limited (AIM: UFO), a minerals exploration and development company, is pleased to note that GreenTech Metals Limited (ASX: GRE) ("GreenTech") has announced the findings of an independent geochemical review of the Munni Munni PGE-Cu-Ni Project (Munni Munni), conducted by Dr Scott Halley, a specialist geochemist with experience in magmatic sulphide systems and layered mafic-ultramafic intrusions. Dr Halley's review has provided a new and compelling framework for understanding the broader untested potential of the Munni Munni intrusive complex, identifying discrete high-priority exploration targets around the base of the intrusion and interpreting the key controls on Cu-Ni-PGE sulphide mineralisation.

Key Highlights:

·	Soil geochemistry demonstrates discrete copper anomalism over the base of the ultramafic sequence, indicating the basal contact of the Munni Munni intrusion is prospective for basal contact-associated Cu-Ni+/-PGE mineralisation
·	The ultramafic lower section of the intrusion has a widespread depleted copper signature indicative of segregation of magmatic sulphides, consistent with basal sulphide accumulation
·	Major element and trace element systematics map out the fractionation processes in the Munni Munni intrusion. The Ferguson Lode is just below the transition from ultramafic to gabbroic rocks, like most other PGE systems, including the Bushveld Layered Intrusive Complex.
·	A ~5km x 2km strong copper anomaly associated with elevated vanadium and titanium values in the upper sequence suggest magnetite rich zones with disseminated magmatic copper sulphides.

Alien holds a 30% interest, free carried to the completion of a bankable feasibility study at Munni Munni, and holds 37.9 million shares in GreenTech, representing an approximate 10% interest in the issued share capital of GreenTech.

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 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. 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.
