Formerly: Demix-Varennes quarry, Saint-Amable sill, Varennes & St-Amable, Verchères Co., Québec, Canada

The Demix-Varennes quarry is an operating quarry and has been characterized by some collectors as a "mini Mont Saint-Hilaire" because of the similarity of its mineralogy(see Mineral. Rec. 29, 83-118). The quarry is exploiting an alkaline sill 12-20 m thick that covers a large area. It is on the municipal boundary of the towns of Varennes and Saint-Amable, hence both names are in the locality string. The gate of the quarry is located at the Varennes end but the workings and crushing plant are in St-Amable (approx. 1.6 km from the gate).
