Mettallium Limited is a company focused on developing critical mineral processing technologies, with a key development in its collaboration with Meteoric Resources to evaluate FJH as an upgrading pathway for mixed rare earth carbonate (MREC) produced from ionic clay rare earth feedstocks.
The Core ESG Action
Mettallium’s primary pillar is “E” for Environmental, and the company has made significant progress in reducing its Scope 1 emissions by 12% in 2026, maintaining zero Long-Term Impacts (LTIs) over 12 months, and establishing a board sustainability compliance committee.
The company’s extracted metrics and actions include reduced Scope 1 emissions and maintained zero LTIs, with ongoing work focused on further optimising this upgrading pathway and evaluating its potential integration with conventional downstream rare earth separation.
ESG Themes and Impacts
The FJH platform has demonstrated substantial germanium enrichment across three distinctly different secondary feedstocks, including zinc smelter waste, semiconductor manufacturing waste, and defence-related industrial waste.
Germanium is used extensively in high-value applications such as semiconductors, fibre optics, infrared optics, defence systems, AI infrastructure, and data centres. Recovering germanium from existing industrial residues offers a potential pathway to create new domestic supply without relying solely on development of new primary mines.
Governance and Regulatory Alignment
Mettallium is engaging with other major rare earth industry participants regarding additional feedstocks and potential commercial applications of the technology, including with the previously announced collaboration with Ucore Rare Metals Inc.
The company’s development activities will focus on optimisation of recovery, selectivity and product purity; further testing of customer and strategic-partner feedstocks; development of feedstock-specific processing flowsheets; evaluation of scale-up and commercial deployment requirements; and progression of current industry discussions towards commercial agreements.
Forward Commitments
Mettallium’s forward commitments include the successful initial campaigns, with ongoing work focused on further optimising this upgrading pathway and evaluating its potential integration with conventional downstream rare earth separation.
The company will continue to focus on optimisation of recovery, selectivity and product purity; further testing of customer and strategic-partner feedstocks; development of feedstock-specific processing flowsheets; evaluation of scale-up and commercial deployment requirements; and progression of current industry discussions towards commercial agreements.
