The property is underlain by the Auclair Formation, consisting mainly of paragneisses, of probable sedimentary origin, which surround the pegmatite dikes to the northwest and southeast. Volcanic rocks of the Komo Formation occur to the north and east of the pegmatite dikes. The greenstone rocks are surrounded by Mesozonal to Catazonal migmatite and gneiss (Franconi, 1978; Moukhsil et al., 2007).
The outcropping pegmatites at the Project are surrounded by a thick sequence of intensely folded paragneiss with minor concordant felsic porphyry sills. The paragneiss can be subdivided into two distinct groups observed in outcrop:
• Strongly bedded paragneiss with associated garnets, staurolite, andalusite, and occasional cordierite observed in drill core.
• Massive, quartz-dominant paragneiss with no bedding textures.
In the eastern portion of the deposit, a feldspar porphyry sill sub crops measuring 5 m to 10 m wide and oriented towards 100° azimuth. It is difficult to ascertain the dip, but this unit has been intersected in drilling and can be traced at depth with a dip of 60° to the south. The unit is strongly porphyritic, with feldspars measuring from 2 mm to 8 mm. The groundmass is predominantly biotite, with a weak foliation. Tourmaline is observed in close proximity to contacts with surrounding pegmatites.
To the north of the outcropping pegmatites, a lithology rich in biotite and amphibole has been identified both in outcrop and dri ........
