Dec 07, 2005 (K R Kettles) - Geological Description: The area is underlain by mafic volcanic flows. In the general area pillow structures are present, indicating that the flow tops are to the north. Drill holes in the area have intersected large gabbroic intrusions, which show local zones of fracturing and carbonatization. Between the basaltic flows are beds of sedimentary iron formation composed primarily of chert, and magnetite. They are generally less than 2 m thick. The occurence is located on what is interpreted to be the northern limb of a long, east-west striking anticline. DEPOSIT DESCRIPTION: The occurence is located near the contact between beds of chloritic, schistose tuff and iron formation. Over 1 m section, thin quartz veins, and silicified lenses occur, and these seem to be the locus for the gold mineralization. About 1 to 3% sulphides also occur in the zone. The iron formation returned low assays for Cu, Pb, and Zn. GEOPHYSICAL DATA: A strong EM anmaly with good magnetic correlation was discovered. This anomoly outlines the iron formation.
