This campaign allowed to define a depth limit of 60m for the hematitic weathered facies, to outline lanthanide rich zones (>2%) in the central part and to recognize the same lanthanides mineralogy and grain size down below the weathered hematitic facies (Bastnaesite and monazite in fine needles or in reddish brown-purple accumulations) (Dénommé & al, 1986). In 1986, Cambior Inc. acquired the Soquem share in the mine and in 2001 Teck Corporation sold their interest to Mazarin Inc. of Quebec City. In December 2003, Sequoia Minerals Inc. was created as the result of a corporate reorganization of the Mazarin Inc. operations whereby the metal and industrial minerals segment (niobium, dolomite and graphite) became a separate corporation (Sequoia). In 2004, Sequoia Minerals Inc. shareholders voted in favor of a takeover offer by Cambior Inc., clearing the way for the company to take full ownership of North America's only niobium mine. In September 2006, IAMGOLD Corporation and Cambior announced their merge to create a new entity. IAMGOLD Corporation Inc. owns 100% of the Niobec mine since November 2006. In September 2011, Niobec Inc., a 100% IAMGOLD Corporation owned company, is created. Niobec Inc. is the operator of Niobec mine and the owner of the beneficial right of the niobium mineral. In August 31 st , an agreement between Niobec Inc. and IAMGOLD granted to IAMGOLD 100% of the beneficial rights to all the non-niobium mineral rights located on the property (including the rights to the REE’s). In 2011, after a long quiet period, REEs became in short supply and prices reached historic highs. A new economic interest for the REE Zone by IAMGOLD-Niobec Inc. boosted the exploration interest by the realization of a first drilling campaign of 29 drill holes totaling 13,798 metres to evaluate the REE resources. In 2012, the exploration program is pursued. A total of 33 new drill holes for 23,851 metres help defined the three dimensional REEs mineralisation geometry, transform the 2011 inferred resources into indicated resources, extend the inferred resources to the depth of 700 m, provide samples for metallurgical test work and increased the REE mineralization knowledge. 3400, chemin du Columbium, St-Honoré-de-Chicoutimi, QC G0V 1L0 Canada – tel. : 418 673-4694 Fax : 418 673-3179 E-mail : info.niobec@iamgold.com www.niobec.com

TOTAL 227 93,217 metres Item 9. GEOLOGICAL SETTING 9.1 Regional Geology The Saguenay region is mainly composed of Precambrian rocks (Figure. 3) belonging to the Grenville orogenic province of the Canadian Shield (Roy, 1977; Laurin and Sharma, 1975; Jooste, 1958; Denis, 1937). The metamorphism reached the upper amphibolite faciesgranulite and at least three generations of folds are superimposed. More recently, the Grenville province was divided three distinct lithostructural units (modified from Belzile, 2009): • The first Unit constitutes a gneiss complex that is divided in three Groups (Groups I, II and III) based on increasing structural complexity from the youngest to the oldest Group. All the rocks from the Group I have been migmatized and deformed during the Hudsonian Orogeny (1,735 million years ago). • The second Unit is represented by anorthosite and charnockite-mangerite batholiths showing well preserved igneous structures and textures. Anorthosite which range from pre- to post Greenvillian age, are regarded as evidence of crustal extension, the Neohelikian extensional tectonics, which continued during the Grenville Orogeny, 3400, chemin du Columbium, St-Honoré-de-Chicoutimi, QC G0V 1L0 Canada – tel. : 418 673-4694 Fax : 418 673-3179 E-mail : info.niobec@iamgold.com www.niobec.com
