Jun 26, 2012 (A Wilson) - The mineralization is hosted by a grey porphyry which is extensively silicified, sericite- carbonate altered and mineralized with pyrite, pyrrhotite and sphalerite. It intrudes a sequence of fine-grained sediments which also display sericite-carbonate alteration. Gold mineralization occurs within the porphyry and within altered metasediments at and near the contacts.

Jun 26, 2012 (A Wilson) - Diamond drilling returned assays up to 3.54 g/t Au over 9.8 m including 4.61 g/t Au over 6.6 m from drill hole GW-04-11.The porphyry is generally massive to weakly sheared. Gold mineralization is erratic within the porphyry and the better grades do not appear to be associated with sulphide mineralization.
