Dec 07, 2005 (K R Kettles) - GEOLOGICAL DESCRIPTION: The occurrence is underlain by a thick sequence of mafic metavolcanic flows. The flows vary from massive and coarse grained to pillowed. Stratigraphic tops are to the west. Foliation strikes NE-SW and dips approximately 80 deg. southeast. A thick unit of metasedimentary rocks overlies the mafic volcanics. The basal part of the sedimentary sequence is primarily composed of garnetiferous conglomerate. DEPOSIT DESCRIPTION: A quartz vein striking S34 deg. E and dipping 15 deg. to 60 deg. to the west hosts the gold mineralization. The vein has been exposed over a length of 27 m.

Dec 07, 2005 (K R Kettles) - MDI1 DATA: GRADE: ASSAYS UP TO 0.03 OPT AU FROM VEIN A quartz vein striking S34 deg. E and dipping 15 deg. to 60 deg. to the west hosts the gold mineralization. The vein has been exposed over a length of 27 m. Assays of up to 0.03 oz/ton (1.029 g/tonne) Au have been reported from the vein.
Dec 07, 2005 (K R Kettles) - The conglomerate in the area is garnetiferous.
