CEM Validates Bauxite-Free Smelter-Grade Alumina Process, Launches PFS

Calgary, AB – September 11, 2026 -- Canadian Energy Metals Corp. (CEM) has validated a proof of concept for producing smelter-grade alumina (SGA) from a non-bauxite resource, and has formally launched a prefeasibility study (PFS) for its Thor project in northeastern Saskatchewan, near Tisdale.

CEM's boehmite conversion process matches Bayer-process alumina purity

Testing on boehmite derived from precursors linked to high-purity alumina (HPA) and chemical-grade alumina (CGA) consistently produced samples matching the purity and technical characteristics of SGA made via the Bayer process, the current industry standard for bauxite refining. SGA is the primary feedstock for metallic aluminum production.
