The Causabiscau Shear Zone transects the Pontax South Property over 16 km, representing approximately 10% of its total length. In addition, another regional Shear Zone, oriented E-W, crosscuts the Property over 6 km. Many Lithium deposits and occurrences are closely and spatially associated to shear zones, evidencing entrapment, and tend to form at or near the contact of mafic, ultramafic or amphibolite rocks which are reported at Pontax South.
