Dec 07, 2005 (K R Kettles) - The property is located southwest of the Dome Stock. The principal rock types underlying the property are, mafic metavolcanic flows and mafic to ultramafic intrusions. Locally, the matavolcanic flows are carbonatized, silicified and deformed, and in the past have been described as felsic to intermediate flows and pyroclastic rocks. The mafic to ultramafic intrusions are sill-like bodies of gabbro and serpentinite. A small body of quartz porphyry outcrops in the eastern part of the property. The gold is hosted in a large quartz vein within the altered mafic metavolcanics. The ultramafic intrusives are indicated by a high magnetic profile. Several VLF-EM conductors have been recognized, and these represent either iron formation units (strong conductors) or shear zones(weak conductors).

Dec 07, 2005 (K R Kettles) - The mafic metavolcanics flows are so highly carbonatized, silicifed and deformed that they were originally described as felsic to intermediate flows and pyroclastic rocks. The mafic to ultramafic intrusiopns are mainly gabbro and serpentinite.

Dec 07, 2005 (K R Kettles) - The No. 4 vein has been delineated by drilling for a total strike length of about 150 m. The vein occurs in altered and deformed mafic metavolcanics. It has an average width of 2-4 m. The vein contains appreciable amounts of sulphides but only low average gold values. Visible gold has been reported from one drill hole. The average grade of the vein is 0.092 opt Au (Durocher et al. 1987).
Dec 07, 2005 (K R Kettles) - The mafic metavolcanic rocks which contain the No. 2 vein have been locally highly carbonatized and silicified, and are very deformed next to the vein.
