Caballos area

Mineralization in the Caballos area may be similar to the Big Pit area. Gold mineralization is exposed by several old workings that exploited quartz veins intersecting a low-angle structure consisting of sheared and folded phyillites and siltstones. The Jurassic sedimentary rocks are likely the same as those in the Big Pit area and have been intensely sheared, folded, cleaved, intruded, altered and mineralized along a brittle-ductile thrust fault zone that coincides with the contact with overlying sandstones. In the Big Pit area, the mineralized zone lies primarily along the low-angle thrust fault and has an average thickness of approximately 10.5 m and encompasses altered and mineralized intrusive dikes. Gold mineralization in the thrust fault is characterized by intense brittle deformation, anastamosing shears, local folding, silicification and slip surfaces that strike north-south and dip to the west. The sedimentary rock units (commonly sandstone) that overlie the thrust fault exhibit areas of silicification, brecciation and are crosscut by numerous quartz veins. In the Caballos area, steeply dipping quartz veins, stockworks, and sheared phyllites show anomalous values up to 5.31 g/t gold.
