Resource-grade mineralization on the Snow Lake Lithium Project is hosted by the Thompson Brothers dike (TBL) on the east side of Crowduck Bay (northeast end of Wekusko Lake) and the Grass River set of four dikes (GR) on the west side of Crowduck Bay; several smaller and/or less intensively mineralized dikes have also been identified in the TBL and the GR.The Thompson Brothers dike has been modelled as an intrusion into a pebble meta-conglomerate / greywacke group of host sediments. The dike has been interpreted as sub vertical, dipping between –81.5° and –87.5° towards 130° azimuth. The trend of the ore body has slight variations and is rolling to the East and West. The dip of the ore body is also rolling slightly. The dike carries both mineralised and unmineralized pegmatite as identified by the presence of spodumene as the lithium bearing mineral. Only the lithium bearing pegmatite has been modelled in this instance which extends for a total length of 1,012 m ranging in true thickness from a maximum of 18 m to a minimum of 1.8 m; however, mineralisation has not been closed off either at depth or to the north or south of the drilled area.The dike is generally orientated between 20° and 40° offset from the apparent foliation in the surrounding country rock and there is outcropping evidence of additional mineralised and unmineralized pegmatite in the area that is yet to be defined in terms of size and or orientation.The dikes on the GR property intrude into older andesitic and monzonitic rocks. The average trend of the dikes is 125° and average dip of 60°. The total depth of the mineralized dikes is 574 m, a total length of 500m and a total width of 200m. As in the TB dikes, the pegmatite bodies have mineralized and unmineralized sections which were distinguished by the presence or absence of spodumene.Mineralization The Flin Flon belt has been the host to a variety of precious base metal and REE deposits. Major mineralizing events took place during the 3 stages of crustal development of the Trans-Hudson Orogen. These deformation events were pre-accretion, post-accretion, and continent-continent collision. Gold and syngenetic base metal gold deposits are associated with the pre-accretionary stage. The syn- post-accretionary stage hosts intrusion-related precious metal deposits. The continental collision stage is the host to orogenic gold and lithium-cesium-tantalum pegmatite deposits.The mineral being sought after at the Snow Lake project is spodumene, a pyroxene group, lithium aluminum silicate (LiAlSi2O6). Interestingly, the TBL and GR spodumene is a light green colour but is Fe-poor.The TB and GR pegmatite dike clusters make up part of the Wekusko Lake pegmatite dike field. Several other dikes have been recorded towards the north along the Crowduck Bay fault. These clusters of dikes are also known as dike swarms. The dikes are all tabular in form and steeply dipping.The Thompson Brothers dikes are located on the east shore of Grass River linking Crowduck Bay to Wekusko Lake. At this location, there are 3 mineralized pegmatite dikes named TB-1, TB-2 and TB-3 that intrude into Missi group pebble to cobble conglomerates and greywackes.The TB-1 dike was drill tested by Nova Minerals in 2017 and 2018 with 24 diamond drill holes, and 30 drill holes were drilled by Snow Lake Lithium in 2022 on the main dike. The TB-1 dike strikes 040° and dips about 85° southeast. It ranges from 2.9-15.4 meters in true thickness but averages approximately 7.7 meters wide.Dike TB-2 is situated to the north of TB-1 and has been traced for about 400 m along strike. This dike has not been located in outcrop and has had minimal drill testing with 8 holes. It is approximately 2.8 m thick and oriented sub-parallel to TB-1. Dike TB-3 is located approximately 250m to the northwest of dikes TB-1 & 2. It is approximately 2.0 m thick and oriented sub-parallel to the other dikes with a strike of 040 and dip of 80° to the northwest.All TB dikes are sub-parallel to the northeast-trending foliation and strata in general. Dike TB-2 could represent the faulted northern extension of dike TB-1, or an en-echelon dilational structure. Dike TB-2 remains open along strike to the north and to depth. Grass River consists of 4 sub-parallel lithium-bearing pegmatite dikes.The dikes on the GR property intrude into older andesitic and monzonitic rocks. The average trend of the dikes is 125° and average dip of 60°. The total depth of the mineralized dikes is 574 m, a total length of 500m and a total width of 200m. As in the TB dikes, the pegmatite bodies have mineralized and unmineralized sections which were distinguished by the presence or absence of spodumene.
