Point Location Description: Scaled off from the No 1 post of claim 41347 using a company plan.
Location Method: Data Compilation
Access Description: Access to Swayze River is easy via the Dore Main Haul Road and the Orofino Access road. At the bridge across the river is a trailer and the drill hole is some 200m southwest along the banks of the Swayze River.
1947 Orofino Mines optioned some ground from Messrs McVittie and Cryderman and drill tested postulated westward extensions on the No 1 vein at the Orofino Mine site. In one hole quartz stringers returned gold values up to 0.7g/t over 0.5m hosted in diorite. Other holes failed to duplicate these values.
