Defense Metals (DEFN.V) has begun a confirmatory pilot flotation plant test program for its Wicheeda Project, the company said on Tuesday.
The program will be conducted at the SGS Canada Inc. metallurgical facility in Lakefield, Ontario, the company said.
The company has engaged SGS Canada to undertake the pilot flotation program, which is designed to confirm the results of the 2021 pilot plant, further advance metallurgical development, generate flotation concentrate for hydrometallurgical pilot plant work, and support future engineering studies for the Wicheeda Project.
The program will use approximately 30 tonnes of drill core material from the Wicheeda deposit in two sub-samples representing planned production from years 1 through 5 and year 6 onwards of the PFS mine plan, said the company.
"The primary objective of the pilot flotation campaign is to generate a representative rare earth flotation concentrate grading approximately 50% total rare earth oxides ("TREO")," said the company. "The concentrate produced during the pilot program will be used in a planned downstream hydrometallurgical pilot plant aimed at confirming and optimising the general process conditions of the PFS with the representative concentrate generated from this pilot flotation program."
In addition to concentrate production, the continuous pilot-scale operation will generate representative process tailings for downstream testing and characterization, said the company and added that the pilot plant will also confirm metallurgical performance under continuous operating conditions while providing "valuable engineering and process design data for future project development activities."
"SGS has completed pre-pilot characterization work, including head assays, grindability testing, laboratory-scale flotation testing, and pilot plant setup activities," said the company.
Pilot plant operations are scheduled to begin on May 12, 2026, and are expected to continue for approximately five weeks.
"We are very pleased to commence this important pilot flotation campaign with SGS Lakefield, which marks another major step in advancing the Wicheeda Project toward development," said Mark Tory, Chief Executive Officer of Defense Metals. "The generation of a representative high-grade rare earth concentrate for downstream hydrometallurgical testing is a critical component in further de-risking the project and refining our process flowsheet. The pilot program will also provide valuable engineering and operational data needed to continue progressing Wicheeda as a potential North American source of rare earth materials."
The company also announced that Michelle Tanguay has been appointed Vice President of Environment and Social Performance.
The company's shares were last seen unchanged at $0.21 on the TSX Venture Exchange.
