Exploration History

MINERALIZATION: ARCHEAN BANDED IRON FORMATION 214M BELOW NIP. DIAB. AND GOWGANDA FM. IN DDH. W.A. Carter (1958) - ground magnetometer survey and diamond drilling recommended. 1959: Thomson and Savage - geology and diamond drilling. 1959: geological, ground magnetometer and dip needle survey carried out at Crest Lake; DD-2-937.9 ft. 2008: Temagami Iron Corporation - magnetometer survey; Scholes- ground magnetometer survey. Mineralization: Archean banded iron formation 214m below Nipissing. diabase. and Gowganda Formation. in DDH. Rio Tinto Canadian Exploration sank a shaft and carried out bulk sampling and a feasibility study which suggested that the deposit was economic. They determined reserves of 108 million long tons grading 29.7 percent soluble iron to a depth of 1750 feet. Later Eagle Rock Iron Mines was formed and determined a reserve of 328 million long tons grading 27.2 percent soluble iron.
