Snow Lake Resources Ltd., (NASDAQ: LITM) d/b/a Snow Lake Lithium Ltd. is pleased to provide an update, and analysis on the recently completed Grass River Project Resource Drilling campaign. Significant intersections are listed in Table 1.0 below for reference. Cross Sections and maps (Figures 1.0 to 4.0) are also available to review as part of this release.
This data will be passed to our resource modeler, with these results to be included in the next MRE following the maiden MRE to be released in July together with the PEA.
The dykes have yielded great results which are anticipated to provide the forthcoming resource with significant upside in terms of grade and tonnage. As noted by several geologists at the core house, several intersections of coarse-grained spodumene pegmatites were logged in multiple holes within the Grass River area.
Based on the initial wireframe modeling of the pegmatite dykes at Grass River, the Company has been able to identify a minimum of three distinctive spodumene bearing pegmatite dykes (Figure 1.0). Snow Lake Lithium’s technical personnel in the field have hypothesized that there could be as many as five distinctive dykes based on core and field observations.
Snow Lake Lithium has engaged ABH Geological Services to assist with modeling the GRP dykes to better understand the three-dimensional composition of the subsurface area and map out drilling patterns for future drill programs that will look to expand the anticipated resources.
Based on the initial wireframe modeling of the pegmatite dykes at Grass River, ABH was able to identify a minimum of three distinctive spodumene bearing pegmatite dykes (Figure 1.0). Snow Lake Lithium’s technical personnel in the field hypothesized that there could be as many as five distinctive dykes based on core and field observations. Due to this higher density of dykes within the Grass River area, Snow Lake Lithium will refer to this area as the Grass River Pegmatite Swarm. Based on these promising results additional drilling is planned for the fall and winter of 2023.
Dale Schultz, Snow Lake’s Project Manager and VP of Resource Development, commented, “We are excited with the drill results received to-date and are increasingly optimistic for the balance of the results to be received from the recent drilling campaign. As evidenced by the high-grade intercepts retrieved from the Grass River Pegmatite Swarm, we can infer additional dykes beyond those identified from the initial scoping study. We look forward to updating the market as those studies progress and remain steadfast in positioning the Company to begin initial site development in 2024 with construction and commissioning of the commercial mine to follow.”

GRP Dykes Swarm
Geology of the GRP dyke Swarm and host rocks – The GRP dykes crosscut plutonic intrusive rocks of Monzonite composition, exhibiting medium to coarse grained Plagioclase crystals within a fine to medium grained mafic groundmass. Albitic to potassic feldspars occur frequently within the rock. The groundmass consists of amphiboles and occasional biotite. Garnet has been observed in small clusters within rare melanocratic groundmass. The Monzite has been subject to considerable seracitic and hematitic alteration, often resulting in destruction of the original plutonic minerals and giving the rock a “bleached” appearance. Small quartz and granitic Aplite dykes are common.
The GRP pegmatite dykes swarm appear to strike 110° and dip about 60-65o SSW. The mineralogy of the dykes is typical for Lithium bearing pegmatite dykes, and consists of potassic feldspars, quartz, muscovite and to a lesser extent biotite, tourmaline and rare garnets and very rare beryl. The lithium bearing mineral is spodumene, which varies considerably in both grain size and distribution within the dykes. Spodumene crystals can vary in size from 1 cm to over 10+ cm in size. The GRP dykes often exhibit very large spodumene crystals, often ranging in size from 10-15 cm long. The distribution of the crystals within the dyke intersections is sporadic, with some sections containing up to 25 to 30 percent Spodumene, and other sections that are Spodumene poor to barren, suggesting multiple pulses of fluids and crystal mush from the parent granitic magma. The mineralogy and mineral zonation of the dyke(s) will be the subject of further study in the coming months.
Analytical – Half core samples are sent to the SGS Lakefield laboratory in Ontario for analysis. Core samples are initially crushed to a size of -12.7 mm, then fragmented to 75% passing 2mm and eventually extruded into a 250 g pulp that is pulverized to 85% passing 75 microns. Samples are sodium peroxide fused and ran on ICP-AES and/or ICP- MS generating 56 element suit.
