Dec 07, 2005 (K R Kettles) - GEOLOGICAL DESCRIPTION: The occurrence is underlain by northeast striking, steeply dipping mafic metavolcanics and metasediments. The mafic volcanic units have been described as mafic tuffs. The metasediments are comprised of an intercalated sequence and mudstone beds. The metasediments appear to overlie the volcanics. Small quartz-feldspar porphyry dikes intrude the volcanics and sediments. Gold mineralization occurs in quartz veins in the mafic volcanics and in sulphide rich porphyry dike. DEPOSIT DESCRIPTION:

Dec 07, 2005 (K R Kettles) - The occurrence is underlain by northeast striking, steeply dipping mafic metavolcanics and metasediments. The mafic volcanic units have been described as mafic tuffs. The metasediments are comprised of an intercalated sequence and mudstone beds. The metasediments appear to overlie the volcanics. Small quartz-feldspar porphyry dikes intrude the volcanics and sediments. Gold mineralization occurs in quartz veins in the mafic volcanics and in sulphide rich porphyry dike. Vein # 3 is approximately 1.5 m wide and is composed mainly of quartz with irregular chlorite inclusions. Minor pyrite and chalcopyrite are also present. Gold appears to be associated with the chlorite inclusions rather than the quartz. Vein # 2 is composed of quartz which is well mineralized with chalcopyrite and pyrrhotite. The footwall contains a band of massive pyrrhotite up to 0.9 m in width. The quartz vein is about 0.78 m thick. Vein # 1 is quite similar to Vein # 3 and gold mineralization associated with the chloritic inclusions. Porphyry dike 'T' is about 3 m wide and well mineralized with pyrite.

Dec 07, 2005 (K R Kettles) - The following are the highest assays that have been reported from the veins: Vein # 1 - 0.02 oz/ton (0.686 g/tonne) Au. Vein # 2 - 0.10 oz/ton (3.429 g/tonne) Au (grab sample) Vein # 3 - 0.02 oz/ton (0.686 g/tonne) Au (chip sample) Dyke T - 0.10 oz/ton (3.429 g/tonne) Au. The heavily mineralized quartz between Veins #1 and #2 is reported to have assayed 0.12 oz/ton (4.114 g/tonne) Au. Vein # 3 is approximately 1.5 m wide and is composed mainly of quartz with irregular chlorite inclusions. Minor pyrite and chalcopyrite are also present. Gold appears to be associated with the chlorite inclusions rather than the quartz. Vein # 2 is composed of quartz which is well mineralized with chalcopyrite and pyrrhotite. The footwall contains a band of massive pyrrhotite up to 0.9 m in width. The quartz vein is about 0.78 m thick. A strong EM conductor coinciding with a strong magnetic anomaly of over 10,000 is located in the area of the occurrence.
