previous work

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.

The Whitemud Lake Property is in the English River Subprovince and is ~8km south of the sub-province boundary with the Uchi sub-province.

Caesium - Lake sediments

Lithium- Lake sediments

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).
