Defense Metals Corp. (TSXV:DEFN) has confirmed the successful completion of flotation tests on variability samples and a master composite (MC) prepared from drill core obtained from its wholly-owned Wicheeda Rare Earth Element (REE) deposit located in British Columbia, Canada.
“Flotation tests on variability samples from the dominant lithological unit of the Wicheeda REE deposit gave an average of 81% recovery to a concentrate assaying 45% rare earth oxide,” Defense Metals’ metallurgical advisor, John Goode, said.
“Wicheeda is one of the few rare earth deposits under development from which a high-grade mineral flotation concentrate can be produced at recovery rates similar to those obtained by current rare earth producers. High-grade concentrates at high recoveries are a critical requirement for positive production economics.
“These successful flotation results help to position Defense Metals’ Wicheeda deposit as one of the best in North America.”
Defense Metals completed flotation tests on variability samples that are representative of the three key REE-bearing lithologies in the Wicheeda deposit:
1) the higher-grade dolomite carbonatite (DC) which makes up 73% of the deposit,
2) the xenolithic carbonatite (XE) that represents 24%; and
3) the syenite (SYN). The primary rare earths minerals are monazite, bastnäsite and synchysite/parisite.
