Geological Age: Archean
Metamorphism Type: Regional
Metamorphism Grade: Amphibolite
Dec 07, 2005 (K R Kettles) - GEOLOGICAL DESCRIPTION: The occurence is underlain by felsic tuff striking E-W and dipping approximately 75 deg. to the south. The tuff is banded with chlorite and carbonate layers. A 2m wide quartz-feldspar porphyry dike cuts across the tuff. A smaller porphyry dike to the south also intersects the tuff. South of the tuff lie beds of intermediate volcanic flows which have been carbonized and/or silicified. In the general area, pillow structures have been observed indicating that the flow tops are to the north. The flows contain varying amounts of sulphides, up to 5% locally. The gold mieralization is contained in the quartz-feldspar porphyry dike. DEPOSIT DESCRIPTION: The quartz-feldspar porphyry dike is the host for the gold mineralization. The dike is approximately 2 m wide and dips approximately 65 deg. to the south. Locally, two ages of carbonated joints dipping at 35 deg. and 70 deg. (younger) are found. No information on the strike length or depth of the dike is available. GEOPHISICAL DATA: A strong EM conductor with moderate magnetic correlation is present.

Dec 07, 2005 (K R Kettles) - A diamond drill hole by Minorex intersected a 2 m zone assaying 0.01 oz/ton (0.343 g/tonne) Au. Several zones up to 2 m. in length contain low values (0.09-0.11%) of copper.
Dec 07, 2005 (K R Kettles) - Weak to moderate carbonization and silicification in country rocks and host rocks. Chloritization has occurred in the felsic tuffs.
