Apr 01, 2014 (A Wilson) - Diamond drilling intersected a 1.4 ft section of semi-massive sulphides at the base of an andesitic unit. The best assays from the andesitic zone returned 0.002 oz/t Au, 0.0001 oz/t Ag, 0.3% Zn, 0.049% Cu and 0.0016% Pb. The conductors are generally due to thin zones of disseminated to semi-massive sulphides.
