Dec 07, 2005 (K R Kettles) - GEOLOGICAL DESCRIPTION: The occurence is situated in an area primarily underlain by mafic metavolcanic flows with thin units of chemical metasedimentary rocks between flow units. The volcanics are strongly foliated, highly carbonized and chloritized. Pillow structures have been noted on some of the islands around the occurence, with tops indicated to the north. The chemical metasedimentary rocks are composed of interbanded chert, graphitic chert, and graphite with occassional disseminations and bands of pyrite and pyrrhotite. The sulphide content of the chert units is low, whereas the graphitic units contain up to 15% pyrite and pyrrhotite. DEPOSIT DESCRIPTION: The highest gold and silver values were found in thin units of graphitic chert with thin bands of pyrite and pyrrhotite.

Dec 07, 2005 (K R Kettles) - A 30 cm section of drill core returned assays of 180 ppb Au and 0.9 ppm Ag. A 68 cm section returned assays of 100 ppb Au and 0.7 ppm Ag.
Dec 07, 2005 (K R Kettles) - The mafic metavolcanics are highly carbonatized and chloritized. Quartz-carbonate veins are rare in the chemical metasediments.
