Dec 07, 2005 (K R Kettles) - The occurrence is situated along the contact between mafic volcanics and the East Bay Serpentinite. The volcanic rocks consist of both pillowed and massive basalt. Near the shore of East Bay, mapping and drilling have shown that the basalts are altered; they consist of alternating brown and green bands, 2 to 8 cm wide, that are characterized by biotite an amphibolite. The East Bay Serpentinite is exposed along the common boundary of claim KRL 260 and KRL 11036, where it consists of fine grained, light weathering rock containing some thread veinlets of asbestos. Talc has been reported from diamond drill holes along the edge of the serpentinite. Intrusive rocks that are present include dikes of quartz-feldspar porphyry and lamprophyre.

Dec 07, 2005 (K R Kettles) - Eight holes were drilled in the vicinity of the main gold occurrence. Gold mineralization was encountered over a strike length of 120 m in 5 diamond drill holes. Mineralization consists of free gold with minor associated sulphides. Drilling and trenching returned many favourable assays. The best values returned were: 0.64 oz/ton (21.942 g/tonne) Au over 30 cm, 0.60 oz/ton (20.571 g/tonne )Au over 60 cm, and 0.50 oz/ton (17.143 g/tonne) Au over 1.08 m. Visible gold was observed in three drill holes and in some of the trenches.
Dec 07, 2005 (K R Kettles) - The metavolcanics contain abundant biotite, and have been locally carbonatized and/or silicified. Talc has been noted in the ultramafic units.
