[{"type":"text","content":"MONTREAL, Quebec / Feb 06, 2023 / Business Wire / Lomiko Metals Inc. (TSX.V: LMR) (“Lomiko Metals” or the “Company”) is pleased to announce an update on the optimization studies of the concentrator flowsheet design and the development of graphite value-add processes, as detailed below. Lomiko Metals completed a pre-feasibility (“PFS”) level flotation flowsheet optimization program that culminated in a flowsheet for the Company’s PFS for its La Loutre property. The samples submitted for metallurgical testing were selected by InnovExplo in Val-d'Or, Quebec. Three different types of composites were generated, mine plan, domain, and grade composites. The mine plan composites represented the first several years of expected mine operations and were blended in the appropriate ratio into a master composite containing material from the EV Zone. This master composite was used in the flowsheet optimization program and produced consistent high-grade flotation concentrates. The total weight of the samples was approximately 640kg. The flowsheet optimization program was carried out by SGS Lakefield Inc. (SGS) using the above samples and the final report was completed by Metpro Management Inc. At the end of the optimization program, this master composite containing only material from the EV Zone was subjected to a locked-cycle flotation test (“LCT”). The LCT simulates the metallurgical performance of a continuous plant operation. The LCT produced a combined concentrate grade of 98.6% C(g) at a closed-circuit graphite recovery of 94.7%. Please refer to Table 1 for details. The robustness of the flowsheet was verified in open-circuit tests with twelve variability composites, which represented different phases in the mine plan, domains, and head grades. The average concentrate grade of the 15 variability flotation tests, which included three repeat tests, was 97.9% C(t) with a low relative standard variation of 1.08%. Taking into account the standard deviation, the lowest value of 95.2% C(t) is considered an outlier. All other tests produced consistently high grades between 96.4% C(t) and 99.7% C(t) as shown in Table 2. Belinda Labatte, CEO and Director stated: “We are very pleased to achieve a high purity of La Loutre’s graphite flotation concentrate in the LCT testing which is indicative of the grades to be produced in the operational setting.
