Ann: 2.3km Outcropping Pegmatite Target Identified, page-254

How good is this description from your link:

"The presence of spodumene lithium deposits in the Montagnes Lake area has been known since the Ministère's mapping work in 1962 (RP 500). Lithium mineralization is hosted in white pegmatitic spodumene-tourmaline-garnet-apatite-muscovite granite dykes cutting amphibolitized basalts of the Lac des Montagnes Group. Metre to hectometre-thick intrusions are oriented NE-SW and dip steeply (60-80°). Spodumene crystals 1 cm to 10 cm long are disseminated in pegmatite with contents varying from 2% to 15%. The Whabouchi deposit represents the typical example of lithium-bearing deposits in the area. Although no showing lithium content has been recorded in the Le Vilin Lake area, pegmatites of the Senay Suite, locally enriched in tourmaline, garnet and muscovite, are relatively abundant and represent a prospective lithology for lithium exploration."

Anyone have a suggestion where the parent source of magma would be?
