Promethium element Critical Material

Promethium is the element Pm, represented here by its neutral-atom identity, distinct from individual isotopes, dissolved ions, mineral species and rare-earth commodity mixtures. Australia's Critical Minerals List, updated on 20 February 2024, includes a rare-earth-elements group whose footnote 17 explicitly names promethium. The designation below is that source's group-member mapping, not a separate individually scored promethium entry or a claim about other jurisdictions. This record contains verified identity and dated criticality; no microbial mechanism or recovery performance is asserted.
