Dec 07, 2005 (K R Kettles) - According to A.C. Bray, the 'O' zone is 152 m north of the Rowan 'C' zone, in sheared mafic volcanic rocks, but these must comprise only thin layers of mafic rocks within the felsic tuff mapped by Riley. The shearing runs in a north-westerly direction parallel to bedding, and the shear zone is silicified and contains numerous auriferous quartz stringers.
