The Forgan Lake Property consists of a 256 ha claim (16 claim units) in the Oskawe Lake Area, approximately 125 km north-east of Thunder Bay, Ontario (Fig. 1).
This property occurs within the Georgia Lake Pegmatite field, an area that has seen moderate Lithium exploration since its discovery in the 1950's. Hosted on the property are 4 previously drilled, spodumene(Fig. 3) bearing (Lithium ore) pegmatites, however the property has yet to be explored to its full economic potential. In 1955, Lun-Echo Gold Mines Ltd. conducted surface mapping, channel sampling and diamond drilling. The property has seen little activity from this time until 2009, when TNR Gold Corp. undertook 2 small surface exploration programs, consisting of prospecting, lithogeochemical sampling and a soil geochemical survey.
Historic sampling of pegmatite #1 returned 2.57 wt% Li2O over 6.4m, 4.23 wt% over 7.5m and 1.98% wt% over 7.6m. TNR's results included 2.57% wt% Li2O over 4m on the same pegmatite and a grab sample yielding 3.61% Li2O (Fig. 3).
In addition to lithium mineralization, the property also has significant Rare Earth Metal potential as historic assaying only tested for Lithium content. The Georgia Lake Pegmatite field is derived from an area of known fertile parent granites which contain incompatible elements such as Cs, Ta, Nb and Rb. Pegmatite #1 yielded 323 ppm Ta2O5 and 1486 ppm Rb2O. Having Lithium in addition to rare earth metals increases the economic potential of the Forgan Lake Property.
