Whitemud LAKe
overview
381 single cell mining claims totaling ~7,775 Hectares
location
- The Property is 41 km northeast of Ear Falls, ON.
- The Whitemud Lake property is located in northwestern Ontario where numerous lithium deposits have been delineated to host significant reserves of Li2O.
- The Property is accessible by a series of logging roads, or via helicopter.
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.

geology
- These terrain boundaries are deep seated structures that divide accreted Archean terranes and can act as conduits for fertile peraluminous granites.
- The Property is underlain by tonalities to granodioritic rocks of the Bluffy Lake batholith in contact with metasedimentary rocks in the north-northeast which have been metamorphosed to the lower amphibolite/upper greenschist facies.
- The Property lies 17 km north of the English River-Winnipeg River Terrane boundary.
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).
