Geology Comments

Dec 07, 2005 (K R Kettles) - GEOLOGICAL DESCRIPTION: The occurrence is situated in a lens of mafic metavolcanic rocks, approximately 2000 m long by 300 m wide. Rocks in this lens strike NE-SW and dip subvertically. Sequences of greywacke and mudstone underlie and overlie the lens of mafic volcanic rocks. Several small quartz-feldspar porphyry dykes have been observed in the mafic volcanic rocks. DEPOSIT DESCRIPTION: Porphyry dyke 'R' is approximately 7.5 m wide. Gold mineralization occurs in small quartz stringers within the porphyry. Quartz vein number 8 is approximately 0.9 m wide and well mineralized with pyrite, pyrrhotite and chalcopyrite. GEOCHEMICAL DATA: In this area, the presence of garnets probably indicates a significant degree of metasomatism. GEOPHYSICAL DATA: A very weak Em anomaly occurs over the occurrence coinciding with a small magnetic high.

Mineralization Comments

Dec 07, 2005 (K R Kettles) - Grade: Dike R - chip sample and grab: 0.16 opt Au over 1.22 m, 0.06 opt Au/4 ft, 0.05 opt Au. Grade - Vein #8: only trace values of gold. A 1.22 m chip sample extending north from the south contact of the quartz porphyry dyke is reported to have assayed 0.16 oz/ton (5.486 g/tonne) Au. Quartz vein number 8 assayed only trace values of gold.



Alteration Comments

Dec 07, 2005 (K R Kettles) - The mafic volcanics are garnetiferous and the porphyry dikes in the area contain abundant quartz stringers.
