The Kanichee layered intrusive complex, also called the Kanichee intrusion and Ajax intrusion, is a layered intrusion in Northeastern Ontario, Canada, located in the central portion of Strathy Township about 6.5 km (4.0 mi) northwest of the town of Temagami. It consists of mafic-ultramafic rocks and is the largest of many mafic-ultramafic intrusions associated with felsic and mafic metavolcanic rocks in the northern Archean Temagami Greenstone Belt.^[1]

Five magmatic cycles have been identified in the Kanichee layered intrusive complex, the first of which formed a PGE deposit with associated gold, copper and nickel mineralization. Ore mineralogy includes pyrrhotite, pentlandite, chalcopyrite and pyrite. The deposit has been quarried by Kanichee Mine.^[1]
