Gold mineralization is developed primarily in the cataclasite unit. Mineralized zones that host gold grades >0.5 g/t Au range in width from 10–110 m. Higher-grade material (>1.5 g/t Au) is developed in the cataclasite, but lower-grade (0.5–1.5 g/t Au) mineralization locally occurs as a 20–50 m wide halo in the hanging wall granitoids.
