 particularly near its north and south contacts where they constitute the bulk of the exposed rock. These pegmatites mainly strike in east direction but north, north-west and 40° east of north strikes are also stated. Generally best mineralization occurs in north and east striking dykes. The Pegmatites are classified simple and complex.

The simple ones contain the same minerals as those found in the muscovite granite which are albite, quartz, microcline, and microcline-perthite with small amount of muscovite. The complex Pegmatite include common minerals of the simple pegmatites with fewer common minerals such as spodumene, columbite, tantalite, lepidolite, beryl, and others, which in places have potential for mineral deposits of economic value.

The pegmatite dykes, sills and lenses can be subdivided into rare-element pegmatites and granitic pegmatites. The rare-element pegmatites are significance, and they contain microcline or perthite, albite, quartz, muscovite, spodumene and minor amounts of beryl, columbite-tantalite and cassiterite.

The deposit model for the area is that the spodumene occurs in Li-Cs-Ta (“LCT”) rare-element pegmatite dykes. LCT pegmatites are associated with S-type, peraluminous (Al-rich), quartz-rich granites. S-type granites crystallize from a magma produced by partial melting of preexisting sedimentary source rock. They are characterized by the presence of biotite and muscovite, and the absence of hornblende. Rare-element pegmatites derived from a fertile granite intrusion are typically distributed over a 10 to 20 km2 area within 10 km of the fertile granite. A fertile granite is the parental granite to rare-element pegmatite dykes.

History

Exploration work in the Property and surrounding area dates to the late 1940s’ with the discovery of lithium showings documented in Quebec Department of Natural Resources. Augustus Prospect was described as a lithiferous dyke oriented N300°/40°, it is documented more than 850 m long and 7.6 m wide on average
