The Whitemud Lake Property has been underexplored. Government mapping in the northwestern part of Whitemud Lake Area township identified several outcrops of pegmatite in the proximity of Whitemud Lake (Fenwick, 1966).
Government lake sediment surveys covered the Property in summer of 2000. The anomalous suite of elements returned from the survey on the Property suggest possible granitic pegmatite source rocks (OGS 2002). The sample sites in the project area returned some of the highest values obtained for Cs, Nb, Li, Sn, Be, Hg , and TI. There were also numerous other sites in the area which also returned elevated to anomalous values of Cs which are covered by the Property.
The term “elevated” indicated analytical results above the 90th percentile, “anomalous” for results above the 95thpercentile and “highly anomalous” for results above the 98th percentile.

Neighbouring, Frontier Lithium’s (TSXV: FL) ‘Electric Avenue SPARK deposit announced 18.8 million tonnes averaging 1.52% Li2O in the Indicated category and 29.7 million tonnes averaging 1.34% Li2O in the Inferred category. Frontier Lithium’s PAK Lithium Project encompasses 26,774 hectares along 65 km of Ontario’s Electric Avenue with four spodumene-bearing pegmatites.
Avalon Advanced Materials’s (TSX: AVL) Separation Rapids property consists of 19 mineral claims and one mining lease covering a combined area of approximately 4,414 hectares with resources of 9.4Mt grading 1.35% Li2O.
The Georgia Lake pegmatite field with resources of 16+Mt grading 1.15% Li2O is owned by Imagine Lithium and Ultra Lithium.
The English River sub-province consists mainly of turbiditic metasedimentary rocks, deposited during the final stages of magmatic and tectonic accretion within the Uchi Subprovince to the north at around ca. 2720 to 2710 Ma. The sedimentary rocks were intruded by a suite of calc‐alkalic plutons at 2698 Ma. Major regional deformation, amphibolite to granulite facies metamorphism, anatexis, and emplacement of an extensive peraluminous granitic suite culminated at 2691 Ma. Late episodes of metamorphism, metasomatism, and emplacement of pegmatites occurred locally at ca. 2680 and 2669 Ma (Corfu, F.1995).
