Golden Goliath's Manicouagan Project now consists of three properties covering anomalous Rare Earth Element occurrences just to the south of the Manicouagan impact crater. Highway 389 splits the properties just north of the Robert Bourassa hydro dam at Manic-5, 215 km north of Baie Comeau. The initial exploration program on these properties consisted of geology and geochemistry as well as the ground radiometric survey and Drone Mag survey completed on Victory 21.

All three properties are underlain by metamorphic and igneous units that are cut by younger pegmatites. It is unclear if the anomalous REE values are associated with the Manicouagan impact event.
