Cautionary Statement

This presentation contains forward-looking statements. All statements, other than of historical fact, that address activities, events or developments that the Company believes, expects or anticipates will or may occur in the future (including, without limitation, statements regarding expected, estimated or planned gold and niobium production, cash costs, margin expansion, capital expenditures and exploration expenditures and statements regarding the estimation of mineral resources, exploration results, potential mineralization, potential mineral resources and mineral reserves) are forward-looking statements. Forward-looking statements are generally identifiable by use of the words “may”, “will”, “should”, “continue”, “expect”, “anticipate”, “estimate”, “believe”, “intend”, “plan” or “project” or the negative of these words or other variations on these words or comparable terminology. Forward-looking statements are subject to a number of risks and uncertainties, many of which are beyond the Company’s ability to control or predict, that may cause the actual results of the Company to differ materially from those discussed in the forward-looking statements. Factors that could cause actual results or events to differ materially from current expectations include, among other things, without limitation, failure to meet expected, estimated or planned gold and niobium production, cash costs, margin expansion, capital expenditures and exploration expenditures and failure to establish estimated mineral resources, the possibility that future exploration results will not be consistent with the Company's expectations, changes in world gold markets and other risks disclosed in IAMGOLD’s most recent Form 40-F/Annual Information Form on file with the United States Securities and Exchange Commission and Canadian provincial securities regulatory authorities. Any forward-looking statement speaks only as of the date on which it is made and, except as may be required by applicable securities laws, the Company disclaims any intent or obligation to update any forward-looking statement.

The United States Securities and Exchange Commission (the "SEC") permits mining companies, in their filings with the SEC, to disclose only those mineral deposits that a company can economically and legally extract or produce. We use certain terms in this presentation, such as "mineral resources" , that the SEC guidelines strictly prohibit us from including in our filings with the SEC. U.S. investors are urged to consider closely the disclosure in the IAMGOLD Annual Report on Form 40-F. A copy of the 2010 Form 40-F is available to shareholders, free of charge, upon written request addressed to the Investor Relations Department.

Total Resources includes all categories of resources unless indicated otherwise.

Mineral mining. The deposit locally outcrops at Resources are estimated at a cut-off grade of 0.30 g/t Au. Mineral Resources are estimated using a gold price of US$1,600 per ounce and metallurgical recovery of surface and, based on the extensive 93.5%. High grade assays are capped at 15 g/t Au and 20 g/t Au depending on sub- domain. Bulk density of 2.71 t/m3 was used for tonalite and breccia and 2.79 t/m3 was drilling program to date, the depth of the used for diorite. The Mineral Resource Estimate is constrained within a Whittle Pit shell using assumed costs and the above noted gold recovery and gold price Mineral barren overburden averages 5.8 metres. Resources are not Mineral Reserves and do not yet have demonstrated economic viability, but are deemed to have a reasonable prospect of economic extraction. Numbers may not add due to rounding. Mineral Resources are reported on a 100% basis; IAMGOLD has a 92.5% average attributable ownership of this project.

ABORIGINAL PARTICIPATION THROUGHOUT EA PROCESS

Version: February 2012 Formal Consultation Opportunity Open Pit

Estimated Dimensions Depth: approx. 650 metres deep Surface area: approx. 210 hectares

Expected Production

Open pit mining rate is expected to be 60,000 tonnes per day

How would it be mined?

The benches in rock would be developed by blasting

Conventional shovel and truck type operation

Ore, mine rock and overburden removed from the open pit would be trucked to the surface

May include an In-pit Crushing and Conveying (IPCC) system

Involves the use of crushing machinery that can be relocated to minimize the vertical haulage component carried out by the haul Typical haul truck Rio Tinto, Palabora Open Pit trucks

13 Mine Rock Areas

Project development is expected to generate: Mine rock: 850 million tonnes 730 hectares by up to 100 metres high Overburden: 20 million tonnes 150 hectares by up to 100 metres high Use:

About 40 million tonnes of mine rock would be used in Project site construction and maintenance (i.e., dams and roads)

Some overburden would be used in final reclamation

Unused overburden and mine rock would be managed on the site

Environmental Impacts – Rock Analysis

Preliminary Results – mine rock is not potentially acid-generating

Further testing is underway to better characterize the rock

Any potentially acid-generating rock would be managed appropriately

14 Ore Processing Plant, Work Camp and Other Buildings

Storage Facility Storage for fuels and process-related

Accommodations Complex 1,200 workers during construction 500 full-time personnel during operation

Ore Processing Plant Area where gold is recovered from ore using metallurgical techniques

15 Tailings Management Facility (TMF)

What are tailings? Tailings are the materials left over after removing the valuable fraction (i.e., gold)

What is the TMF?

Facility constructed to manage the tailings

Size: approx. 900 hectares

Storage capacity: approx. 330 million tonnes of tailings

Dams: constructed rockfill dams and naturally high bedrock surface

Dam heights (maximum): 45 to 50 metres above ground surface

Water: a large portion of the excess water in the TMF would be recycled for process water

Remaining water would be discharged through a polishing Examples of Tailings Management Facilities pond to surface water and would meet applicable Federal and Provincial effluent discharge standards

Closure: the TMF would be rehabilitated (for example re-vegetated) at closure based on the Ministry of Northern Development and Mines approved Closure Plan

16 Power Transmission Line

Power for Project operations would be powered by a new 230 kilovolt transmission line connected to the existing HydroOne Network in Timmins at the Porcupine Substation

Proposed alignment First segment, approx. 120 kilometres long, would parallel an existing 115 kilovolt transmission line from Timmins to Shining Tree Second segment, approx. 40 kilometres long, would be constructed within an existing right-of-way from the Shining Tree Substation to the Project site

Proposed alternative alignment More direct (shorter) route (cross-country) is being evaluated and may be incorporated into the environmental assessment if the evaluation looks promising

Aboriginal, Stakeholders and Government Consultation Activities and Information Sources

First Nation and Métis groups (as identified by Federal and Provincial governments) Meetings and open houses

Gogama and other regional communities Site tours (Sudbury, Timmins) Newsletters/Newspaper notices Provincial and federal governments Project website (www.iamgold.com) Neighbours and adjacent land owners (Mesomikenda cottagers, mining interests, Direct mail/e-mail to project mailing list trappers, hunters)

Interested stakeholders (Economic development agencies, businesses, forestry companies,

Non-governmental environmental organizations (Northwatch, Mining Watch Canada)

18 Côté Gold Project: Current Activities on Project

Employ 50 people at the Côté Gold Project site; half of whom live in Gogama and surrounding communities.

Local contracts in place for services such as: hauling, clearing brush, making roads, pipe fusing, making core boxes, and carpenters.

Drilling Continue to define the resource and explore property holdings

Additional Baseline Work Aboriginal traditional knowledge and land use Air Quality Archaeology Aquatics and Terrestrial Geochemistry Groundwater and Surface Water Socio-economics Visual Aesthetics
