Walkinshaw Lake Lithium Property

The Walkinshaw Lake Property is a lithium exploration opportunity located only 23 km north of Thunder Bay, Ontario.

The Walkinshaw Lake Property occupies the southern Quetico Subprovince boundary zone with Wawa Subprovince. This general area was included in a province-wide reconnaissance project (Operation Treasure Hunt) that examined peraluminous granites and their associated rare-element pegmatites. With respect to this area, samples collected along the Armstrong Highway (Hwy 527) transect revealed increased fractioning of pegmatites toward the southern (Onion Lake-Walkinshaw) and northern (Smiley-Scandrett-DeCourcey) boundary zones.

The following recommendation was provided as an outcome of the Highway 527 transect in Operation Treasure Hunt (OFR6099):

Fertile granites occur along a 45 km long stretch of the Armstrong highway between Walkinshaw and DeCourcey lakes. The authors wanted to determine what part of this area had the most potential for pegmatites, so the authors collected and analyzed garnet samples throughout the area. The south end of the Armstrong highway near Onion and Walkinshaw lakes contains manganese-rich garnet (>30% spessartine component), whereas the rest of the highway section contains iron-rich garnet. Thus, the authors propose that the south end of the Armstrong highway is a good prospect when searching for rare-element pegmatites. The reconnaissance work done by this survey indicates that chemically evolved pegmatitic rocks occur along the northern and southern subprovince boundary zones of the Quetico Subprovince, especially at Onion Lake and Walkinshaw Lake.

Next Steps

Next steps for this property include additional grassroots prospecting to identify the location and orientation of pegmatites, observe the characteristics of the pegmatites and collect samples for geochemical analysis to further determine the degree and direction of fractioning and test for the presence of rare-element mineralization.
