Dec 07, 2005 (A Wilson) - Grab samples collected by Corona Corporation returned values up to 8.0 g/t. Chip samples show a high of 3.0 g/t Au over 20 meters. Gold values are associated with pyrite that is spatially related to quartz veins. The distribution of quartz-ankerite veining varies considerably from ladder-style to flat-lying to sub-parallel and sub-vertical.
Dec 07, 2005 (A Wilson) - Strong silica, ankerite, pyrite and feldspar alteration are associated with sections returning the best gold values.
