As next door neighbour Perpetua Resources Inc (PPTA.NAS, A$5bn market cap) partners with the Idaho National Laboratory (INL) to host, commission and operate a flexible, modular pilot processing plant expected to be capable of recovering critical and defense-related minerals.
Resolution Minerals Ltd (ASX: RML; OTCQB: RLMLF) is pleased to announce the appointment of Dr Adam Roper as Chief Metallurgist – Critical Metals Extraction, to lead the development and implementation of the Company’s antimony, tungsten and gold processing strategy. Dr Roper’s appointment further enhances Resolution’s strategy to become a leading U.S.-aligned critical minerals processing partner for the Pentagon’s defense metals requirements.
Dr Roper, PhD (Antimony Geochemistry), is a highly accomplished metallurgist and chemical processing specialist with over a decade of experience spanning process development, piloting, flowsheet optimisation and the design of innovative extraction solutions for complex and strategic metals. His technical leadership and demonstrated capability in delivering large-scale, multistakeholder projects make Dr Roper a key strategic addition to Resolution as it builds its downstream U.S. critical minerals strategy.
Adam’s expertise in critical metals processing, complex chemistries and flowsheet commercialisation is a major asset for Resolution. His deep technical capability - particularly in antimony - strengthens our competitive position and accelerates our path toward establishing a North American supply solution for high-value strategic minerals. We look forward to working closely with him as Resolution advances Horse Heaven into its next phase of development
Dr Roper’s appointment to Resolution comes at an opportune time, with the U.S. military confirming on 9 December 2025 that it plans to develop a fleet of small-scale refineries to produce critical minerals used to make bullets, armour and other types of weaponry, a move aimed at developing domestic sources for niche materials that Chinese miners have long controlled. The plans are being developed by the U.S. Army alongside the Idaho National Laboratory and antimony and gold miner Perpetua Resources Inc (PPTA.NAS, A$5 billion market cap) (which is directly adjacent to RML’s Horse Heaven project), with antimony being the first mineral the military aims to refine.
