Chibougamau Val D'or

East Cadillac Group

Property Summary

The immediate vicinity of the East Cadillac Group has been the focus of exploration activity since the mid-1940s when gold-bearing structures were found near the Cartier Resources Chimo Gold Mine (now closed), which operated for nearly 15 years and produced over 349,000 ounces until its closure in late 1996. The East Cadillac Group hosts numerous catalogued gold occurrences, several with historic resources. The Nordeau West deposit, 1,500 m east of the closed Chimo Mine, hosts a NI 43-101 Mineral Resources, the only current resource on the property, with an inferred resource of 1.1 Mt at 4.09 g/t.

The properties comprising the East Cadillac Group overlay a highly sheared sequence of altered greywacke, iron formation and mafic volcanic rocks along nearly 15 kilometres of strike. Gold mineralization is found associated with quartz veins containing disseminated to semi-massive sulphides, typically within sedimentary rocks in close association with magnetite iron formations or sheared and altered mafic volcanic rocks.
