Dec 07, 2005 (A Wilson) - Mineralization is hosted in massive basalts. These basalts are part of a sequence of Fe tholeiitic massive and pillowed flows with intercalated tufaceous horizons. The basalts intersected in the hole are predominantly fine-grained, though there are local medium to coarse grained intervals. Pyrite and pyrrhotite are common accessories, but occur in low concentrations disseminated throughout the basalt and also are locally concentrated in aggregates together with calcite. A stockwork of hairline carbonate veins occur locally, and even more restricted are some minor quartz veins with adjacent epidote-carbonate alteration.

Dec 07, 2005 (A Wilson) - In hole HW85-1a 3 m interval (between 165 and 175 feet) of massive sulphide veins has been reported. An examination of the core shows that this interval contains coarse grained sulphides (2 - 3 mm) in loose aggregates or trails. There are a numbe rof these trails in the upper and lower part of the interval and the total sulphide percentage is less than 5%. Pyrrhotite is the dominant sulphide with lesser amount of pyrite and chalcopyrite. Grab samples returned values of 0.82 g/t Au, 0.35 g/t Ag and 0.8 % Cu.
