The La Grande Project is located between 50km to 190km east of Radisson in northwest Quebec, Canada. The Project comprises three key prospects:
Joule Prospect - located 50km south-east of Radisson consisting of 320 claims covering approximately 16,385 hectares;
Aero Prospect - located 150km east of Radisson consisting of 101 claims covering approximately 4,980 hectares; and
Aqua Prospect - located 190km east of Radisson consisting of 172 claims covering approximately 8,803 hectares.

The La Grande Project is situated within the east-central portion of the Superior Geological Province, in the middle of the Canadian Shield. The Superior Province extends from Manitoba to Quebec and is predominantly comprised of Archaean age lithologic units. The La Grande Sub-province borders the plutonic Bienville sub province to the north and is bounded to the south by the metasedimentary and plutonic Opinaca sub province. Collectively, the La Grande and Opinaca sub-provinces host a significant number of the known spodumene pegmatite occurrences in Quebec.

The Joule Prospect covers an area of approximately 16,385 hectares along the Robert-Bourassa reservoir. The area is the host to the Duncan Intrusions suite of Neoarchean Age. This unit, composed of generally foliated hornblende and biotite tonalite.
The Joule Deformation Zone (“JDZ”) on the property is approximately 21km long and trends for 7km at 110° northwest to southeast before turning northeast at about 070° for 14km. It continues within volcanic greenstones northwest underneath the LaGrande reservoir for a distance of 22km. From this point it continues all the way northwest to the James Bay coast but in less favourable tonalites and monzonites.
The western segment of the JDZ extends for 7km on the property. This section is marked by a dextral fault to the south and a series of shear zones located north of the main dextral fault. In places the deformation is up to 1000m wide and at its narrowest point is about 500m wide. This section is also marked by a series of northeast trending normal faults that basically chop the JDZ into segments. Due to its overall complexity in the western segment, and government stratigraphic surveys identifying pegmatites and pegmatite textures in the area, this area is deemed to be the most prospective area of the property of LCT pegmatite dykes.
The eastern segment of the JDZ extends for 14km on the property and consists of a series of northeast trending shear zones that extend to the northeast limit of the property. The deformation zone at the far northeastern part of the property fan tails to reach a width up to 1.5km. A deformation zone of greater than 800m is considered to indicate prospectivity for LCT Pegmatites in the area. The JDZ provides plenty of structural "Space" for the injection of pegmatite dykes with similar subduction fault widths of those seen at Winsome’s Cancet and Adina properties, and Patriot’s Corvette property.

The Aero Prospect consists of 101 continuous claims covering an area of 4,980 hectares. The Aero Property has approximately 13km of deformation zones which are considered highly prospective for LCT Pegmatites. The nearby Cancet (Winsome) and Corvette (Patriot) properties both have deformation zones running through their properties and have had significant success along these zones.
Aqua

The Aqua Prospect consists of 172 continuous claims covering an area of 8,803 hectares. The geology of the local area touches three Archean sub-provinces (La Grande, Bienville, Opinaca) and includes gabbro dykes and a Proterozoic arenitic basin. Regional faults transverse the property from ESE to WNW which hosts the La Grande Greenstones which are considered highly prospective for LCT Pegmatites.
