Dec 07, 2005 (K R Kettles) - Geological description: The prospect is underlain primarily by altered basaltic flows. Near the No. 2 vein, abundant pillow structures have been observed. They are locally up to 1 m in size and indicate a top direction to the northwest. In some areas, altered basalts are coarse grained. Small dikes of dioritic composition are present. Feldspar porphyry has been noted in the area, but is uncommon. Tuff and siliceous sediments are present between altered basalt flows. Sedimentary rock units are generally less than 5 m in thickness. They strike 090 deg. and dip 85 deg. S. Generally the rocks show little deformation but at a few localities small shears striking roughly N60 deg. W and dipping steeply south have been observed. Deposit description: A shear zone with a strike of approximately N 60 deg. W cuts the altered basaltic flows and iron formation. The shear is less than 2 m in width and is not well exposed. Given the location and strike of the shear, it is possible that it is a continuation of the No. 1 vein.

Dec 07, 2005 (K R Kettles) - High gold values were reported from grab samples by Redruth in 1945, but no numbers were given. R. Riley grab sampled the area in 1970, and assays of up to 0.01 oz/ton (0.343 g/tonne) Au and 0.60 oz/ton (20.571 g/tonne)Ag were returned.
Dec 07, 2005 (K R Kettles) - A weak carbonate alteration occurs associated with the quartz veins.
