Dec 07, 2005 (A Mitchell) - The claims are underlain by an NE-SW striking, moderately to vertically dipping, intercalated sequence of slates, quartzites, greywackes and conglomerates. Dikes of quartz porphyry, diorite, and lamprophyre intrude the sedimentary rocks. A 5 m to 12 m wide band of slate, containing lenses of quartzite is the locus for the quartz veins. The quartz is clear to bluish in colour and granular. Tourmaline is present along the margins of the veins.

Dec 07, 2005 (A Mitchell) - Work has outlined a zone approximately 25 m long, 2 m wide and extending to a depth of 75 m containing auriferous quartz veins. Most of the zone is comprised of a large quartz vein approximately 20 m long and 2 m wide. The other veins are considerably smaller and pinch out along strike and with depth. The quartz lens is reported to have assayed 0.685 oz/ton at surface and 0.15 oz/ton across 1 m at the 450 m level.
