Defense Metals Ships Mixed Rare Earth Carbonate Samples to two major REE companies

Press Release

News Release – Vancouver, British Columbia – March 4, 2024: Defense Metals Corp. (“Defense Metals” or the “Company”; TSX-V:DEFN / OTCQB:DFMTF / FSE:35D) is pleased to announce that samples of mixed rare earth carbonate (“MREC”) have been shipped to two major Rare Earth Element (“REE”) companies. Samples generated by SGS Canada Inc. in Lakefield, Ontario during 2023 hydrometallurgical piloting test work performed on concentrate produced by earlier flotation pilot plant testing of a 26-tonne bulk sample taken from the Company’s wholly-owned Wicheeda deposit have now been sent to almost every REE separator in the world.

MREC samples shipped to the recipients are independently verifying the high-quality of the REE product from the Wicheeda deposit, and further establishing Defense Metals’ Wicheeda REE Project as a critically important, future North American source of rare earths.

Craig Taylor, CEO of Defense Metals, commented:

“Defense Metals continues to advance the Wicheeda Project, establishing it as one of the few western world REE projects that has the key characteristics required for a viable REE project including: (1) location and superior logistics, (2) minerology, metallurgy, and grade, (3) the ability to produce a REE product as established by pilot plant operations , (4) significant potential mine life, and (5) social licence and support of the McLeod Lake Indian Band. Defense Metals believes strongly that Wicheeda will play a key role in establishing North American REE supply chains; first and foremost, with respect to mining and hydrometallurgical processing, and ultimately with respect to the onshoring of downstream REE separation, refining and metallizing capabilities. Defense Metals is positioned as one of the very few North American REE companies having true ability to achieve this vision.”
