Alien Metals Limited (AIM: UFO), a minerals exploration and development company,  is pleased to announce that further to the Company’s announcement on 1 December 2025 (the “Announcement”), it has completed its partial asset sale and joint venture transaction with Australian publicly listed company; GreenTech Metals Limited (ASX: GRE) (“GreenTech”) in respect of the Munni Munni Platinum-Palladium-Copper-Nickel Project (“Munni Munni” or the “Project”) and surrounding tenements in the West Pilbara region of Western Australia (“Transaction”).

Executive Chairman, Bruce Garlick, commented:

“This Transaction with GreenTech Metals Limited is a meaningful step in executing Alien’s partner-led strategy. We have secured a high-quality joint venture partner to advance Munni Munni, while retaining a 30% interest that is free carried through to completion of a bankable feasibility study. This structure preserves exposure to the upside while materially reducing funding requirements and execution risk for Alien shareholders.”

“Alongside the consideration received under the Transaction, Alien owns 30.5 million shares in West Coast Silver Ltd which, as at 30 January 2026, were worth approximately A$6.7 million. These equity positions represent a material asset for the Company and further strengthen Alien’s balance sheet and portfolio leverage.”
