NEWS RELEASE

IAMGOLD REPORTS RECORD PRODUCTION, RECORD NET EARNINGS, RECORD OPERATING CASH FLOW FOR THE FOURTH QUARTER

All amounts are expressed in US dollars, unless otherwise indicated.

Toronto, Ontario, February 24, 2011 – IAMGOLD Corporation (“IAMGOLD” or “the Company”) today reported its unaudited consolidated financial and operating results for the fourth quarter ended December 31, 2010. Net earnings were $144.5 million ($0.39 per share), an increase of $191.9 million compared to the fourth quarter of 2009, and operating cash flow was $221.3 million ($0.59 per share(1)), representing an increase of 228% from the fourth quarter of 2009.

“We had an excellent fourth quarter, with a 35% increase in gold production the key driver behind record highs in net earnings and cash flow,” said Steve Letwin, IAMGOLD’s President and CEO. “Gold production was at the top end of our latest guidance reflecting the hard work and resourcefulness of our employees. These strong financial results, however, were overshadowed by the death earlier this month of an employee of a contractor at our Rosebel mine in Suriname. We are saddened by this tragic accident and extend our deepest sympathies to his family. Safety is, and will continue to be, our top priority.”

“Our plan in 2011 is to build on our strong operational competencies to maximize the growth potential of our core gold assets,” continued Mr. Letwin. “With our strong performance in 2010 and a 13% increase in gold reserves, we are on track to achieving our production target of 1.1 to 1.2 million ounces of gold for the year. We continue to assess the business alternatives to unlocking the value of our niobium asset, and together with our focus on organic growth, are powerful drivers of future performance and improved shareholder returns.”

  • Commercial production at Essakane began on July 16, 2010. Total attributable production in 2010 was 122,000 ounces at a cash cost(3) of $429 per ounce. Throughput continued to ramp up with over 22,000 tonnes per day in December 2010, and is in line with its goal of 25,000 tonnes per day while processing soft rock.

Niobium Operation

  • Strong niobium production of 4.4 million kilograms in 2010, 7% higher than production in 2009, and an operating margin(4) of $18 per kilogram compared to $20 per kilogram in 2009.

Exploration

  • Exploration expenditures of $86.3 million in 2010 included accelerating work on promising results at the Company’s joint ventures in West Africa and the Charmagne discovery in Suriname. These successes supported supplemental funding approval for both near-mine exploration and greenfields exploration in 2010 along with aggressive programs planned for 2011.

Reserves

  • The proactive exploration program at IAMGOLD resulted in increases in reserves and resources.
  • Gold proven and probable reserves increased by 1.9 million ounces, or 13%, to 16.4 million ounces.
  • Niobium proven and probable reserves increased by 34% to 243.8 million kilograms of contained niobium pentoxide (Nb2O5).

Development Projects

  • The Westwood project is on track to commence commercial production in early 2013. Shaft sinking achieved a depth of 1,063 metres at the end of 2010.
  • The Sadiola sulphide project feasibility study was completed and a construction decision is expected to be made in the first half of 2011.
  • On February 9, 2011, IAMGOLD received $49 million in cash from Rio Alto Mining Limited (“Rio Alto”) for the sale of its La Arena project. In addition, as part of the option and earn-in agreement in June 2009, IAMGOLD received 8 million shares of Rio Alto with an approximate market value of $18 million as of February 23, 2011.

REVIEW OF 2010 RESULTS

Financial Results

  • Revenues were $1,167.2 million in 2010, a 28% increase from 2009 primarily due to higher realized gold prices. The average realized gold price in 2010 for IAMGOLD’s operations and joint ventures rose 31% compared to 2009 and the number of ounces of gold sold increased by 2%.
  • In 2010, net earnings were $279.8 million ($0.75 per share) compared to $114.1 million ($0.32 per share) in 2009. Adjusted net earnings(2) of $285.7 million ($0.77 per share(2)) increased by 68% compared to $170.0 million ($0.48 per share) in 2009. The impact of higher sales and gold prices was partially offset by increases in mining costs and income and mining taxes.
  • Operating cash flow was $415.1 million ($1.12 per share(1)) in 2010, an increase of 62% compared to $257.0 million ($0.73 per share) in 2009. The increase is mainly due to increased sales partially offset by higher mining costs and income and mining taxes.

Financial Position

  • The Company’s cash, cash equivalents and gold bullion (at market value) position has improved with $411.3 million available at December 31, 2010 compared to $300.1 million available at December 31, 2009. During 2010, cash and cash equivalents increased mainly due to record cash flow from operating activities, partially offset by capital expenditures in mining assets and exploration and development projects. The Company’s financial position reflects an increase of $167.9 million compared to September 30, 2010 as Essakane ramped up towards its design capacity during the fourth quarter of 2010. As at December 31, 2010, $350.0 million of unused credit remained available under the Company’s credit facility.
  • On February 9, 2011, IAMGOLD received $49 million for the sale of its La Arena project. The proceeds add to IAMGOLD’s strong financial position.
  • On February 24, 2011, IAMGOLD entered into an agreement for a private placement of flow-through shares. The issuance of 1.7 million shares at a price of $25.48 per share raised gross proceeds of C$43.3 million.
  • In 2011, the Company plans to incur $460.0 million in capital expenditures and approximately $51.0 million in exploration expenses. With strong cash, cash equivalents and gold bullion positions, the available credit facility and expected operating cash flows, the Company has the financial capacity to fund the continuing 2011 requirements of exploration and development projects and expansion of existing operations.

Production and Cash Costs

Gold production and cash costs In 2010, IAMGOLD’s attributable gold production increased by 28,000 ounces, or 3%, compared to 2009. The increase in production was a result of:

• Ramp-up of production at Essakane after achieving commercial production on July 16, 2010, and

  • Higher throughput at Tarkwa, Rosebel and Mupane,

Partially offset by:

  • Closure of the Doyon mine in December 2009 and mining the Mouska mine at a reduced rate in 2010, and
  • Lower grades at Sadiola and Yatela.

The 2010 annual average cash cost(3) of $574 per ounce has increased $113 per ounce from $461 per ounce in 2009 mainly due to lower grades, higher energy costs, and higher royalties of $13 per ounce.

Average annual cash costs at IAMGOLD operated sites (Rosebel, Essakane, Mupane and the Doyon division) were $525 per ounce(3) during 2010, an increase of 16% compared to $453 per ounce during 2009. The weighted average cash cost for IAMGOLD’s two main operations (Rosebel and Essakane) was $471 per ounce which highlights the strong performance in 2010. Cash costs for the Company’s joint ventures and working interests (Sadiola, Yatela, Tarkwa and Damang) were $657 per ounce during 2010, an increase of 39% compared to $473 per ounce during 2009.

As gold prices rise, lower grades of ore become economical to mine. By choosing to mine these lower grade deposits of the ore body and managing the cut-off grade, the Company can mine previously uneconomical portions of its resource base, increase the yield from the ore bodies and extend the life of the mines. Notwithstanding increased costs, this yields positive cash flow for the Company. IAMGOLD's continuous improvement programs and cost control efforts focus on aggressively managing unit operating costs (such as cost per tonne mined and cost per tonne milled) and increasing productivity at the operating sites. Increases in the gold price and increased royalty rates have driven higher royalty amounts.

Niobium production and operating margin Niobium production increased in 2010 compared to 2009, resulting primarily from higher throughput. The site successfully completed the paste backfill project and the mill expansion project in the second and third quarter of 2010, respectively. The operating margin per kilogram of niobium(4) decreased by $2 per kilogram during 2010 compared to 2009, the result of commissioning the paste backfill process, the strengthening in the Canadian dollar and higher prices and volumes of aluminum used in processing. Paste backfill process will enable near complete extraction of the ore body including areas with lower grades, impacting mining costs and operating margin.

Development Projects

In 2010, the Company’s total development project expenditures were $260.7 million, mainly related to Essakane in Burkina Faso and Westwood in Northern Québec.

Burkina Faso – Essakane mine – Achieved commercial production effective July 16, 2010

Construction of the Essakane mine is completed and commercial production began on July 16, 2010. Final costs for the construction of the project totalled $464.8 million which was on plan.

Canada – Westwood project – On schedule for early 2013

Completion of the Westwood project is on schedule with commercial production planned for early 2013. Project expenditures in 2010 totaled $94.9 million, with significant infrastructure preparation and construction. Shaft sinking has reached 1,063 metres compared to 1,220 metres expected during the year mainly due to the excavation of a loading station at a higher level than originally planned. More excavation has also been completed on level 60-0 and 84-0. The significant exploration and resource delineation programs resulted in over 74,000 metres of drilling in 2010.

In 2011, significant progress will continue, including the following projected activities: completing the construction of the surface waste silo to allow ore development to begin by the end of 2011, achieving the current shaft sinking plan (1,560 metres by end of 2011), and carrying out an 82,000-metre infill and extensions drilling program for resource development.

South America – Ecuador – Quimsacocha project

The Company has obtained the requisite permits to allow the use of reservoir water for exploration and feasibility work. Regular contact and dialogue is maintained with senior government officials in order to obtain clarity on fiscal and other matters. A model mining contract, which is expected to clarify some of these issues, is being developed by the Ecuadorian government.

Exploration

IAMGOLD’s exploration efforts remain focused in West Africa, select countries of South America, and the province of Québec in Canada. With a strategic mandate for organic growth, the Company has numerous projects underway and continues to pursue additional advanced exploration joint ventures and acquisition opportunities that will strengthen the foundation for future growth.

In 2010, IAMGOLD incurred $86.3 million on exploration projects, a 35% increase from $63.8 million in 2009. The 2010 expenditures included:

  • Near-mine exploration and resource development expenditures of $48.7 million, including a resource expansion and delineation drilling program of more than 94,000 metres at Rosebel in Suriname for $14.7 million, a drill delineation program of more than 40,000 metres at Essakane in Burkina Faso for $13.4 million, and an $8.7 million exploration and resource delineation drilling program of more than 74,000 metres at the Westwood development project in the province of Québec; and
  • Greenfield exploration of $37.6 million conducted at 16 projects, including two advanced exploration sites, in 10 countries in Africa and the Americas as part of IAMGOLD’s long-term commitment to reserves replenishment and organic growth.

Reserves

In 2010, the proactive exploration program at IAMGOLD resulted in a total proven and probable mineral reserves increase of 1.9 million ounces to 16.4 million ounces of gold, a 13% increase over the previous year.

Total proven and probable mineral reserves of niobium increased by 34% to 243.8 million kilograms of contained Nb2O5.

Commitment to Zero Harm Continues

In 2010, IAMGOLD was awarded the Corporate Social Responsibility award at the Corporate and Community Social Responsibility Conference for its Zero Harm vision of maintaining the highest standards in human health, minimizing the impact on the environment, and working co-operatively with host communities.

The frequency of all types of serious injuries across IAMGOLD during 2010 increased marginally to 0.58 compared to 0.54 in 2009.

The Company is committed to connecting its Zero Harm vision to performance, and regrets the tragic deaths of an employee at the Niobec mine in the province of Québec in 2010 and, more recently, an employee of a contractor at the Company’s Rosebel mine in Suriname.

The importance of continually striving for Zero harm is a core value for IAMGOLD. The Company strives to eliminate all injuries and tragedies through programs that reinforce the importance of constant vigilance in the workplace and the adoption of safe work practices. Recently, IAMGOLD joined the Mining Safety Roundtable, an industry forum for the industry’s most safety-focused leaders.

REVENUES

Fourth quarter record revenues of $459.0 million were up 73% over $265.3 million for the same quarter of 2009. This increase was primarily due to an increase in gold sales from IAMGOLD’s operations and joint ventures, and an increase in related realized gold prices.

Record revenues for the full year of 2010 were $1,167.2 million, a 28% increase over the previous year mainly resulting from the increase in realized gold prices.

MINING COSTS

Mining costs in the fourth quarter of 2010 were $216.1 million, a 55% increase over $139.2 million for the same quarter of 2009. Mining costs for the full year of 2010 reached $570.6 million, a 28% increase over the previous year.

The increase in mining costs was due to growth in production, higher consumables costs as well as higher labour costs at Rosebel, higher energy costs across all sites, increased royalties from a rise in gold prices, and adjustments to asset retirement obligations at Doyon due to changes to remediation plans.

DEPRECIATION, DEPLETION AND AMORTIZATION

Depreciation, depletion and amortization decreased from $153.8 million in 2009 to $132.7 million in 2010 due mainly to the increase in reserves for gold sites and Niobec. This decrease was partially offset by additional depreciation expenses following the beginning of commercial production at the Essakane mine during the third quarter of 2010.

EARNINGS FROM WORKING INTERESTS

Year over year earnings from working interests increased mainly as a result of higher sales and higher realized gold prices, partially offset by higher mining costs.

CORPORATE ADMINISTRATION

Corporate administration expenses in 2010 were $46.9 million compared to $49.1 million in 2009. The decrease was primarily related to process improvements, costs containment and one-time costs in 2009 related to the Essakane acquisition.

EXPLORATION AND DEVELOPMENT EXPENSES

Exploration and development expenses in 2010 were $46.0 million compared to $39.8 million in 2009. Exploration expenses in 2010 included accelerating work on promising results at the Company’s joint ventures in West Africa and the Charmagne discovery in Suriname.

NET INTEREST EXPENSE

Net interest expense in 2010 was $3.6 million compared to $0.7 million in 2009. The increase is mainly due to costs associated with maintaining the increased credit facility.

FOREIGN EXCHANGE GAIN/LOSS

The foreign exchange loss in 2010 was $1.7 million compared to a foreign exchange gain of $27.0 million in 2009. The majority of the foreign exchange loss during 2010 and the gain in 2009 were related to the impact of foreign exchange variation on cash held in Canadian dollars. The amount was larger in 2009 resulting from the equity financing in Canadian dollars during the first quarter of 2009.

DERIVATIVE GAIN/LOSS

The total derivative loss was $13.3 million in 2010 compared to a gain of $7.0 million in 2009. The loss in 2010 was mainly due to the market variation of gold option contracts for the Mupane mine, which were undertaken to support a positive cash flow for the remaining limited life of the operation. In addition, the derivative loss was impacted by foreign exchange and heating oil option contracts, partially offset by the positive change in the fair value of warrants held as investments.

OTHER INCOME/EXPENSE, NET

The total other income, net was $24.4 million in 2010 compared to other expense, net of $1.8 million in 2009. The other income/expense, net in 2010 was mainly related to gains on disposal of marketable securities.

NON-CONTROLLING INTERESTS

The total non-controlling interests charge in 2010 was $18.2 million compared to $8.8 million in 2009. The increase is mainly due to the inclusion of the Essakane operation in 2010.

INCOME AND MINING TAXES

The Company does not recognize tax benefits on losses generated in countries where the recent history of operating losses do not satisfy the “more likely than not” criterion for the recognition of deferred tax assets. Consequently, there are no income tax benefits recognized on the pre-tax losses in these jurisdictions as valuation allowances are recorded to offset the associated benefit.

In 2010, income and mining taxes totaled $135.4 million compared to $108.0 million in 2009. The income tax rate varies from the combined federal and provincial income tax rates of 31% in 2010 and 33% in 2009 primarily due to fluctuations in exchange rates for foreign currency, the geographic distribution of income, non-deductible expenses, withholding taxes related to repatriations of international earnings, and the existence of valuation allowances.

Operations Summary

The Company’s 2010 gold operations are summarized below.

ROSEBEL MINE, SURINAME

Rosebel achieved record gold production in the fourth quarter and full year 2010, which was higher than the same periods in the prior year by 20% and 1%, respectively. This strong production level was achieved despite lower grades and a difficult rainy season. The Rosebel site achievement was the result of record throughput levels, higher productivity and operational efficiencies. Moreover, the fourth quarter benefitted from increased recoveries resulting from the commissioning of additional leach tanks.

Cash costs per ounce(3) increased 6% in the fourth quarter of 2010, compared to the same period last year, primarily due to higher energy, labour and consumables costs, and higher royalties due to rising gold prices. Cash costs per ounce have increased by 22% on a full year basis for similar reasons. In addition, grades were lower as the mine was unable to access higher grades in previous quarters of the year due to higher precipitation levels in the rainy season.

In 2011, the Company began another expansion at Rosebel. The expansion will result in additional grinding capacity to allow mill throughput to be maintained between 12 and 14 million tonnes per year offsetting the impact of processing increased hard rock volumes. The expansion essentially brings gold production forward in time and reduces long-term fixed costs by reducing the currently planned mine life.

ESSAKANE MINE, BURKINA FASO

Essakane gold mine achieved commercial production effective July 16, 2010. Attributable production during the fourth quarter and full year 2010 was 80,000 ounces and 122,000 ounces, respectively. Attributable production nearly doubled during the fourth quarter over the third quarter of 2010 despite a two-week shutdown in November caused by an electrical failure at the SAG mill. Cash costs(3) since the beginning of commercial production were $429 per ounce compared to life of mine estimate of between $400 and $410 per ounce.

A feasibility study to expand the mine is currently in progress and is expected to be completed in the third quarter of 2011. The study is expected to demonstrate that the hard rock capacity of the mill could be expanded to process 10.8 million tonnes per year, compared to the current estimate of 5.4 million tonnes per year. The expectation is for life-of-mine average annual gold production between 450,000 and 470,000 ounces (on a 100% basis) compared to the current estimate of 315,000 ounces. The current mine plan includes processing of soft rock for the first three years at a rate of 9.0 million tonnes per year, followed by approximately nine years of processing hard rock.

DOYON DIVISION, CANADA

Gold production at the Doyon division declined in the fourth quarter and for the full year in 2010 compared to 2009. The decline in production reflects the closure of the Doyon mine in December 2009 and reduced production at the Mouska mine nearing the end of its life. As a cost reduction initiative, the ore mined from Mouska during the first eight and a half months of 2010 was stockpiled and batch processed starting mid-September and completed in December.

Cash costs per ounce(3) increased during the fourth quarter and full year of 2010, largely due to lower production, higher royalties due to higher gold prices and the impact of a stronger Canadian dollar on the operation.

MUPANE MINE, BOTSWANA

Gold production at Mupane increased in the fourth quarter and for the full year in 2010 by 36% and 12%, respectively, compared to 2009. The increase was the result of higher throughput levels with improved performance of the ball mill in the current year which was unavailable for the second half of 2009. Cash costs per ounce(3) for the fourth quarter and the full year of 2010 rose mainly due to higher mining and energy costs. This is the result of more volume of material mined coupled with longer hauling distances from more distant pits and higher diesel fuel prices.
