Oct 22, 2010 (A Wilson) - The sulphides are described as disseminated within the gabbro. A composite grab sample collected by R. Ginn (OGS) from the shaft dump returned 2.92% Cu and 0.41% Ni. Grab samples collected at the shaft muck pile by Mustang Minerals returned: 0.31% Cu, 1.28% Ni, 0.142% Co, 213 ppb Pt and 254 ppb Pd; a second sample returned 5.42% Cu, 0.62% Ni, 0.070% Co, 178 ppb Pt and 151 ppb Pd. A grab sample taken by Mustang Minerals from a trench south of the shaft in 2002 returned 0.99% Cu, 0.64% Ni, 0.083% Co, 27 ppb Pt and 96 ppb Pd. The sample analysed by Mustang Minerals was reportedly pyrrhotite rich. Grab samples collected by Mustang Minerals in 2001 returned values up to 2.95% Cu+Ni, 0.09% Co and 240 ppb PGM.
