Discussion of Results
This week’s drill results are for five holes from two different pegmatite dykes, including four from the BIG East swarm (YLP-0074, 76, 77, 108) and one from Fi Southwest (YLP-0081). A table of composite calculations, some general comments related to this discussion, and a table of collar headers are provided towards the end of this section.

BIG East Pegmatite
The BIG East pegmatite swarm comprises a 35-90 m wide corridor of parallel-trending dykes that dips around 55°-75° degrees west and extends for at least 1,100 m along surface and 200 m downdip.
YLP-0074 was designed to test the BIG East swarm just 50 m south of the dyke swarm’s northern mapped extent and 25 m vertically beneath the surface. Drilling intersected two pegmatite dykes in 33 m of core, with first dyke intercepted over 4 m and the second 22 m but including three 1-2 m wide septa of metasedimentary country rock. Assays from the lower dyke returned 0.82% Li2O over 22 m, including an interval of 1.35% Li2O over 10 m.
YLP-0076 was drilled 600 m south of YLP-0074 to test the BIG East swarm some 550 m from its southern mapped extent and 50 to 100 m vertically beneath the surface. Drilling intersected eight, 2-8 m wide pegmatite dykes that are separated by at least 3 m of country rock and sum up to a total 37 m of pegmatite or approximately 40% of the 90 m interval. Five of these dykes returned assay composites between 1.00-1.38% Li2O over core widths of 1-5 m; one returned 0.55% Li2O over 5 m, and the two narrowest dykes, which bookend this 90 m interval, returned negligible grades.
YLP-0077 was drilled approximately halfway between YLP-0074 and YLP-0076, approximately 300 m from the northern end of the BIG East swarm and tested 150-200 m below the surface. Drilling intersected two dykes over 39 m of drill core, with the upper intercept approximately 4 m wide and the lower dyke 25 m. Assay results for the lower dyke returned a composite of 1.35% Li2O over 22 m whereas the upper dyke returned 1 m of 0.47% Li2O and otherwise negligible results.
YLP-0108 was drilled between YLP-0076 and YLP-0077 to test the BIG East swarm approximately 550 m from its northern mapped extent and 75 m vertically below the surface. Drilling again intersected two dykes over 39 m of drill core, with the upper dyke approximately 14 m wide and the lower one 17 m. Assay results for the upper dyke returned a composite of 1.27% Li2O over 14 m whereas the lower dyke returned 1.28% Li2O over 15 m (Table 1 and 2, Figures 2, 3 & 4).

Fi Southwest Pegmatite
The Fi Southwest (SW) pegmatite is one of several dykes occurring within a longer and wider north-northeast striking dyke corridor. The Fi-SW dyke itself is 25-30 m wide, dips 60°-80° to the east-southeast and extends for at least 1,100 m on surface and 200 m downdip.
YLP-0081 was drilled to test the Fi-SW pegmatite 50 m from its known northern end and 150-200 m vertically below the surface. Drilling intersected three, 5-14 m wide, pegmatite dykes over 39 m of core length, for cumulative pegmatite thickness of 22 m (or 56% of this interval). Assay composites from the upper- to lower-most dyke include, respectively, 1.20% Li2O over 3 m, 1.33% Li2O over 3 m, and 0.98% Li2O over 10 m (Table 1 and 2, Figures 5 & 6).

Drilling Progress Update
Currently, LIFT has reported results from 82 diamond drill holes (14,451 m). The Company concluded its initial drill program at the Yellowknife Lithium Project with 198 diamond drill holes completed (34,238 m).
All five holes described in this news release were drilled broadly perpendicular to the dyke orientation so that the true thickness of reported intercepts will range somewhere between 65-100% of the drilled widths. A collar header table is provided below.
Mineralogical characterization for the YLP pegmatites is in progress through hyperspectral core scanning and X-ray diffraction work. Visual core logging indicates that the predominant host mineral is spodumene whereas other significant non-lithium bearing phases include quartz and feldspar.

QA/QC and Core Sampling Protocols
All drill core samples were collected under the supervision of LIFT employees and contractors. Drill core was transported from the drill platform to the core processing facility where it was logged, photographed, and split by diamond saw prior to being sampled. Samples were then bagged, and blanks and certified reference materials were inserted at regular intervals. Field duplicates consisting of quarter-cut core samples were also included in the sample runs. Groups of samples were placed in large bags, sealed with numbered tags to maintain a chain-of-custody, and transported from LIFT’s core logging facility to ALS Labs (“ALS”) laboratory in Yellowknife, Northwest Territories.
Sample preparation and analytical work for this drill program were carried out by ALS. Samples were prepared for analysis according to ALS method CRU31: individual samples were crushed to 70% passing through 2 mm (10 mesh) screen; a 1,000-gram sub-sample was riffle split (SPL-21) and then pulverized (PUL-32) such that 85% passed through 75-micron (200 mesh) screen. A 0.2-gram sub-sample of the pulverized material was then dissolved in a sodium peroxide solution and analysed for lithium according to ALS method ME-ICP82b. Another 0.2-gram sub-sample of the pulverized material was analysed for 53 elements according to ALS method ME-MS89L. All results passed the QA/QC screening at the lab, all inserted standards and blanks returned results that were within acceptable limits.
