The R2D2 property, 100% owned by Matamec, consists of a series of 66 claims separated in two blocks in the Pontiac sub-province, about 20 km south of the town of Cadillac. These claims straddle the northern edge of the Decelles Reservoir Batholith which intruded metasedimentary clastic rocks (Pontiac schists). The property is being explored for lithium, beryllium and tantalum.
The claim acquisition was determined by the presence of Be, Li, Ta-mineralized granitic pegmatites which were examined and/or mapped by Boily et al. (1989). There are three main showings, the most important revealing granitic pegmatites mineralized in Li and Be and located on the western side of the Chemin du Rapide-Deux in the Montanier Township.
