Item 4. INTRODUCTION AND TERMS OF REFERENCE
This report was prepared by the Niobec mine site geological team and summarized the 2012
works conducted on the Rare Earth Elements exploration project for IAMGOLD Corporation.
The surface diamond drilling exploration program was realised about 1 km North of the
underground Niobec mine activities, St-Honoré, Quebec. Based on the mining and the
metallurgical knowledge, the exploration focused on delimiting and characterizing the rare
earth elements mineralized zone while defining and increasing the mineral resources.
Geological data in this report comes from different sources. Over the 35 years of mining at
Niobec, internal documents (internal Gems database, internal report, MRNFQ GM filed,
historical maps and drilling data, etc.), provided numerous information to the geology
department. All the references are available in the Item 23. This report is the results of a
compilation and interpretation of the geological description and the geochemical analysis of
thirty three new surface diamond drill holes completed in 2012 in a well-known geological
environment.
The main authors of the report are M Louis Grenier, Geo. and M Jean-François-Tremblay,
Geo., respectively exploration geologist and senior geologist for IAMGOLD on Niobec site.
Both supervised all the REEs exploration project operation, conducted by Niobec employees
and specialized contractors on mine site, and are responsible for the Item 7 to 26 (property,
geology and data), except Item 18 and 19, of the report. Pierre Pelletier, Eng. and Vicepresident
metallurgy at IAMGOLD, contributed to Item 18 (processing) and Réjean Sirois,
Eng., Vice President Geology and Resources at G. Mining Services Inc. is responsible for the
Item 19 (resources). Marie-France Bugnon, P.Geo., General manager Exploration for
IAMGOLD and Steve Thivierge, Eng. Special projets and geology Superintendant at Niobec
contributed to the overall edition of the report. All six persons above are qualified persons
(QP) according to the NI 43-101 guidelines.
Item 5. RELIANCE ON OTHER EXPERTS
5.1 Other Data Source
The technical material considered in the present report is based on the existing data produced
by IAMGOLD. This material includes a technical report complying with the NI 43-101
published in 2009, 2011 and 2012 relating to the Niobec mine, a technical report complying
with the NI 43-101 published in 2012 relating to the REEs zone and various other technical
reports regarding the St-Honoré Carbonatite Complex hosting the niobium and REEs depots.
Item 23 provides a full list of reference documents used in preparing this report. In the
production of this NI 43-101 technical report, the authors has relied on the data collected
essentially by new drilling on the REEs zone in 2011-2012 and by producing an updated
compilation of geological data.
