VANCOUVER, British Columbia, Sept. 23, 2024 (GLOBE NEWSWIRE) — Li-FT Power Ltd. (“LIFT” or the “Company”) (TSXV: LIFT) (OTCQX: LIFFF) (Frankfurt:WS0) is pleased to report results from the metallurgical sampling program completed in 2023 and 2024 across eight spodumene deposits within the Yellowknife Lithium Project, Northwest Territories, Canada. Metallurgical test work comprised of heavy liquid separation (HLS) testing, dense media separation (DMS) testing, and batch flotation testing was executed by SGS Canada Inc. (“SGS”) in Lakefield, Ontario. Testing was completed on samples from the Big East (BigE), Big West (BigW), Nite, Ki, Echo, Fi Main (FiM), Fi Southwest (FiSW), and Hi pegmatites.
Table 1- Summary of Results
Francis MacDonald, CEO of LIFT comments, “We are very pleased to report that the comprehensive metallurgical testing studies in preparation for our upcoming Preliminary Economic Assessment (PEA) yielded positive results. Studies notably included pilot-scale DMS testing that indicated that this lower-cost separation method is suitable for the spodumene-enriched pegmatite dikes that are targeted for the more accessible early mining sites that we envision could comprise lithium production in the district for a generation or more. As such the results of these important studies underpin the high value potential for our Yellowknife lithium project.”
Details of metallurgical program
Lithium chemical analysis of the metallurgical samples was performed by sodium peroxide fusion digestion followed by inductively coupled plasma optical spectroscopy (ICP-OES). Whole rock analysis (WRA) was performed by borate fusion and X-ray Fluorescence (XRF). Elemental compositions of the pegmatite samples are presented in Table 2. Pegmatite sample grades ranged from 0.86% to 1.46% Li2O and from 0.24% to 0.48% Fe2O3.
Table 2: Chemical analysis of the metallurgical samples
The mineralogical compositions of the metallurgical samples were determined using the semi-quantitative XRD and are shown in Table 2 . Spodumene concentrations in the pegmatites ranged from 11.0% to 18.3% and are in line with lithium concentrations (i.e., spodumene is the dominant lithium-bearing mineral identified). Minor amounts (1%) of triphylite (LiFe(PO4)) was detected in the FiM sample. Muscovite concentrations in the pegmatite samples ranged from 4.5% to 7.8%. Minor quantities (<1%) of iron-bearing minerals (e.g., chlorite, chlinochlore) were detected.
Table 3 – Metallurgical sample mineralogy from semi-quantitative XRD. Only minor amounts of non-spodumene lithium-bearing minerals were found in samples with ~99% of lithia being hosted in spodumene.
Heavy Liquid Separation (HLS) tests were performed on eight metallurgical samples. The samples were sourced from saw-cut channel samples on the surface of the various dykes. The samples were stage-crushed to a top crush size of 6.35 mm. The -6.35 mm +0.85 mm fraction was submitted for HLS testing which achieved global lithium recoveries ranging from 29% to 68% (interpolated to 5.5% Li2O concentrate grade). HLS test results are presented in Figure 1.

Pilot-scale DMS was operated on each metallurgical sample. Two-stage DMS was undertaken on five of the samples (i.e., BigE, BigW, Nite, Ki, and Echo) and a single-stage DMS was operated on three of the samples (i.e., FIM, FiSW, and Hi).
For the two-stage DMS tests, global lithium recovery ranged from 49.9% to 60.4% with spodumene concentrate grade ranging from 5.81% to 6.41% Li2O with relatively low iron content ranging from 0.62% to 0.88% Fe2O3. For single-stage DMS operation (pre-concentrate production), global lithium recovery to the fines and sinks stream ranged from 93.0% to 95.2%. Pre-concentrate grades ranged from 1.90% to 2.02% Li2O and 0.53% to 0.55% Fe2O3.

Three sets of flotation tests were performed on head samples or products from DMS operation (fines and DMS Stage 1 sinks or fines and Stage 2 DMS floats). For the flotation tests undertaken on the head samples, all samples produced roughly 5.5% Li2O spodumene concentrate with lithium recovery ranging from roughly 69% to 72%. For flotation tests undertaken on the fines and stage 2 DMS floats, 5.5% Li2O spodumene concentrate was produced with lithium recovery ranging from 56% to 75% (Figure 2). For flotation tests undertaken on the fines and stage 1 DMS sinks, 5.5% Li2O concentrate was produced with lithium recovery ranging from roughly 66% to 77% (Figure 3).

Overall laboratory lithium recoveries were calculated based on the DMS and batch flotation test results. Results for the two-stage DMS and flotation flowsheet produced combined concentrates ranging in grade from 5.75% to 6.17% Li2O and lithium recoveries ranging from 81% to 87%. Tests undertaken with a single-stage DMS pre-concentration step followed by flotation produced concentrates ranging in grade from 5.59% to 5.77% Li2O with laboratory-scale lithium recoveries ranging from 61% to 72%.
