Li-FT reviews metallurgical test results at Yellowknife

LIFT REPORTS LABORATORY METALLURGICAL RECOVERIES AVERAGING 79% PRODUCING A HIGH-QUALITY SPODUMENE CONCENTRATE GRADING 5.83% LI2O AT THE YELLOWKNIFE LITHIUM PROJECT

Li-FT Power Ltd. has released the results from the metallurgical sampling program completed in 2023 and 2024 across eight spodumene deposits within the Yellowknife lithium project in the Northwest Territories, Canada. Metallurgical test work comprised heavy liquid separation (HLS) testing, dense media separation (DMS) testing and batch flotation testing, executed by SGS Canada Inc., in Lakefield, Ont. 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.

Francis MacDonald, chief executive officer of Li-FT, 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 emission 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 an attached table. Pegmatite sample grades ranged from 0.86 per cent to 1.46 per cent Li2O and from 0.24 per cent to 0.48 per cent Fe2O3.

The mineralogical compositions of the metallurgical samples were determined using the semi-quantitative XRD and are shown in an attached table. Spodumene concentrations in the pegmatites ranged from 11.0 per cent to 18.3 per cent and are in line with lithium concentrations (spodumene is the dominant lithium-bearing mineral identified). Minor amounts (1 per cent) of triphylite (LiFe(PO4)) was detected in the FiM sample. Muscovite concentrations in the pegmatite samples ranged from 4.5 per cent to 7.8 per cent. Minor quantities (less than 1 per cent) of iron-bearing minerals (such as chlorite and chlinochlore) were detected.

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 dikes. The samples were stage crushed to a top crush size of 6.35 millimetres (mm). The minus 6.35 mm plus 0.85 mm fraction was submitted for HLS testing, which achieved global lithium recoveries ranging from 29 per cent to 68 per cent (interpolated to 5.5 per cent Li2O concentrate grade).

Pilot-scale DMS was operated on each metallurgical sample. Two-stage DMS was undertaken on five of the samples (BigE, BigW, Nite, Ki and Echo) and a single-stage DMS was operated on three of the samples (FIM, FiSW and Hi).

For the two-stage DMS tests, global lithium recovery ranged from 49.9 per cent to 60.4 per cent, with spodumene concentrate grade ranging from 5.81 per cent to 6.41 per cent Li2O, with relatively low iron content ranging from 0.62 per cent to 0.88 per cent Fe2O3. For single-stage DMS operation (preconcentrate production), global lithium recovery to the fines and sinks stream ranged from 93.0 per cent to 95.2 per cent. Preconcentrate grades ranged from 1.90 per cent to 2.02 per cent Li2O and 0.53 per cent to 0.55 per cent 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 per cent Li2O spodumene concentrate with lithium recovery ranging from roughly 69 per cent to 72 per cent. For flotation tests undertaken on the fines and stage 2 DMS floats, 5.5 per cent Li2O spodumene concentrate was produced with lithium recovery ranging from 56 per cent to 75 per cent. For flotation tests undertaken on the fines and stage 1 DMS sinks, 5.5 per cent Li2O concentrate was produced with lithium recovery ranging from roughly 66 per cent to 77 per cent.

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 per cent to 6.17 per cent Li2O and lithium recoveries ranging from 81 per cent to 87 per cent. Tests undertaken with a single-stage DMS preconcentration step followed by flotation produced concentrates ranging in grade from 5.59 per cent to 5.77 per cent Li2O, with laboratory-scale lithium recoveries ranging from 61 per cent to 72 per cent.
