Point Location Description: Outcrop of iron formation along the shore of the Wakami River just north of the tp boundary
Location Method: Data Compilation
Access Description: Access is by way of Highway 667, south of Chapleau, between Highway 129 and the town of Sultan. Take the Kormak Road north past the Canadian National Railway line. A logging road leads north into Greenlaw Township and a smaller bush road will take you to Hotstone Lake. To reach the showing, travel by canoe down the Wakami River about 4.5 km.
1958: T. Clement conducted an airborne magnetic and electromagnetic survey over a small block of claims that straddled the Wakami River and included the iron formation showing along the west shore. 1959: The Anaconda Company (Canada) Ltd. conducted a ground electromagnetic and geological survey on a small block of claims to the immediate north of the iron formation outcropping on the lower Wakami River. 1972: Dome Exploration conducted a diamond drill program to the west of the Wakami River in southern Greenlaw Township. Two of the three holes intersected iron formation hosted within intermediate to felsic metavolcanics. 1990: M. Tremblay conducted a sampling program over a number of properties in the Greenlaw area. This program included several whole rock analysis in the area around South Greenlaw Iron to the west of the Wakami River. 2010: Sino Minerals Corp. – AEM, AMag.
