Dec 07, 2005 (A Wilson) - The multiple iron ranges found in the Goudreau area are presumably folded, faulted and tectonically thickened portions of a single iron formation. This iron formation occurs at the contact between the intermediate to felsic metavolcanics of cycle one and the intermediate to mafic metavolcanics of cycle two. In general, the iron formation becomes thinner and the carbonate facies disappears as one moves eastward into the Kapuskasing Structural Zone. The major difference between the Goudreau iron formations and the iron formation north of Wawa is that the siderite of the carbonate facies at Wawa is calcite east of Goudreau. The occurrence lies within the southern domain of the Goudreau Lake Deformation Zone. This domain is located immediately south of the Maskinonge Lake sock and is composed of brittle to brittle-ductile high-strain zones.

Dec 07, 2005 (A Wilson) - The occurrence is located in an area of poor outcrop exposure. Several outcrops of heavily gossan stained material occur at the contact between mafic metavolcanic rocks to the north and felsic to intermediate metavolcanic rocks to the south. Diamond drill logs indicate strongly sheared and interdigitated mafic metavolcanics and iron formation.
