GreenTech Metals Quarterly Activities Report

Alien Metals Limited (AIM: UFO), a minerals exploration and development company, notes that GreenTech Metals Limited (ASX: GRE) ("GreenTech"), in which Alien Metals holds an investment, has today released its Quarterly Activities Report for the period ended 30 June 2026.

During the quarter, GreenTech continued to advance its flagship Munni Munni PGE-Copper-Nickel Project and the adjacent Whundo Copper-Zinc-Gold Project in Western Australia.

Highlights:

·	Results from the Phase 1 drilling programme at the Munni Munni Project demonstrated new, thicker platinum group element ("PGE"), copper and nickel mineralised zones, while also validating historical drilling through twin hole drilling and core resampling.
·	GreenTech continued work on a JORC (2012) Mineral Resource Estimate for the Munni Munni Project, with resource re-estimation focused on copper-dominant domains and metallurgical testwork advancing the production of a primary copper-PGE concentrate and supporting Net Smelter Return (NSR) parameters.
·	Following the quarter end, an independent geochemical review identified a 5km by 2km copper anomaly and discrete high-priority exploration targets around the base of the Munni Munni intrusion. Government co-funded Fixed Loop Electromagnetic (FLEM) surveys have commenced to test for conductors that may represent massive sulphide accumulations ahead of follow-up drilling.
·	GreenTech announced mobilisation for its upcoming drill programme at the Munni Munni and Whundo Projects, comprising approximately 4,750m of reverse circulation drilling and 3,560m of diamond drilling. Drilling will initially focus on existing cleared drill pads ahead of a heritage survey scheduled to commence on 10 August 2026.
·	GreenTech strengthened its technical team through the appointments of Heida Mani and Rachel Backus and remains fully funded following its A$7.5 million placement.

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 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.
