The Smiley Lithium Property consists of 5 mining claims comprising 1,902 hectares located 55 km north of Thunder Bay, Ontario. The property has excellent highway and secondary road access and is close to rail, port facilities, personnel and mining supplies.
A muscovite-bearing granite, is host to the Property, an S-type peraluminous fertile parental granite (Breaks et al., 2003) that is in contact with meta-sediments. The Property straddles a sub province boundary, an integral relationship between lithium deposits and structure (Breaks et al., 2003). Several mapped muscovite-tourmaline granite pegmatites have been mapped by the OGS within the peraluminous granite with one mapped in the meta-sediments which is an excellent exo-contact for fractionating pegmatites.
The Smiley Lake Lithium property is located in northwestern Ontario where numerous lithium deposits have been delineated to host significant reserves of Li2O. Of significance, lithium deposits of Northwestern Ontario are located within 20km of a terrane boundary. These terrane boundaries are deep seated sutures that divide accreted Archean terranes and act as conduits for fertile peraluminous granites. The Property straddles the Marmion-East Wabigoon Terrane boundary.
Significant lithium deposits of northwestern Ontario include:
The Seymour Lake Lithium Project hosts 4.8Mt grading 1.24% Li2O and 186ppm Ta2O5.
The Georgia Lake pegmatite field with resources of 16+Mt grading 1.15% Li2O.
Separation Rapids Lithium deposit with resources of 9.4Mt grading 1.35% Li2O.
Up to 3.4 m wide quartz-feldspar mica pegmatites intersected commonly described with green alteration of feldspar (potentially spodumene as it can have a greenish tint and look like feldspar and not recognized by the logger). Other highlights include:
- Blue transparent angular crystals (most likely beryl but not known to the core logger).
- Coarse grained muscovite.
- Possible tourmaline or columbite-tantalite.
- A inexpensive trace element package was used that did not include Li or Be analysis.
Sample results show highly elevated Cs, Ta and Rb values indicative of a LCT-pegmatite (Li, Cs, Ta) type commonly found in northwestern Ontario lithium deposits and occurrences.
The average crustal levels for the following rare-elements were Be (3ppm), Cs (4ppm), Ga (17 ppm), Li (20 ppm), Nb (25 ppm), Rb (112 ppm), Sn (6 ppm) and Ta (2 ppm)(Breaks et al., 2003). The levels from the HTX pegmatite samples are well above these levels and are excellent fractionation indicators along host rock fractures as these rare-elements are incompatible with rock-forming minerals and will wait to the last possible moment to crystallize.
