The Sha claims are underlain by moderately east dipping Precambrian Middle Aldridge Formation sediments. These sediments are dominantly medium to thin bedded wackes and quartzitic wackes which are intruded by gabbro sills and dykes. The area is bounded on the east and west by 2 major north trending faults: the Iron Mountain Fault on the west and on the east by the Kidd Creek Fault. A number of minor northeast and northwest striking left lateral normal faults have been mapped on the property.
