A pyroxene[C quartz diorite stock of the Cretaceous to Tertiary Coast Plutonic Complex intrudes Jurassic Hazelton Group volcanics. A quartz vein, about 15 centimetres wide, occurs along the hangingwall of a fissure within a pyroxene granodiorite phase of the Legate Creek apophysis. The vein, exposed intermittently for 300 metres, is mineralized with tetrahedrite, galena, sphalerite and malachite.
