SHEAR ZONE OPEN TO THE NORTH, SOUTH AND AT DEPTH TO THE WEST
Oldest rocks in the region are Proterozoic to mid Paleozoic rocks assigned to the pericratonic Shuswap metamorphic complex. These rocks occur in a north trending belt east of Okanagan Lake and extend north past Shuswap Lake
In fault contact with the Shuswap rocks are late Paleozoic sedimentary and volcanic rocks assigned to a pre-Nicola Group island arc assemblage termed the Harper Ranch Group. These rocks occur in a 35 by 10 km EW trending band extending from SW of Cherryville to the east
Top Shear Zone
Based on trenching and drilling information, has been traced for 170 metres
Appears to vary from NNE trending and steeply west dipping at higher elevations to <30 degrees West dipping at depth with the horizontal width increasing with depth from <1m to >10m
Interpretably been offset by east-west and north-south faults with local west side up displacement
Shear zone and associated spatially concentrated mineralization is open to the north, south and at depth to the west
The known high grade Top 1 Gold Zone is a <10m (in radius) west plunging body extending from ‘trench 2’ within a large, similarly oriented apparently deformed, variably altered and mineralized intermediate Tertiary dyke inside the Top shear
