American Rare Earths (ASX: ARR) is pleased to announce the appointment of Mark Wall as Chief Executive Officer, effective 5 January 2026. Mr. Wall brings more than 30 years of global mining experience across operations, project development, permitting and construction in gold, copper, diamonds and uranium, including senior leadership roles with Tier 1 majors and North American developers. His track record in advancing complex projects from study phase through financing, construction and operational ramp up is directly aligned with American Rare Earths' transition from explorer to future U.S. producer of rare earth elements. Anchored by the world class Halleck Creek project in Wyoming, American Rare Earths has recently delivered a series of pivotal milestones, including a significantly upgraded mineral resource estimate for the Cowboy State Mine, breakthrough impurity removal test work in its processing flowsheet, and an expanded relationship with Tetra Tech to progress U.S. funding and permitting pathways. Under Mr. Wall's leadership, the Company will focus on completing the Halleck Creek pre-feasibility study, advancing design and delivery of a demonstration plant, leveraging U.S. government programs to pursue non-dilutive funding, and preparing the Company for a potential U.S. listing to broaden its investor base and better reflect its U.S. project footprint.
