TORONTO, Feb. 19, 2014 /CNW/ - IAMGOLD Corporation ("IAMGOLD" or "the Company") today announced its 2013 year-end mineral reserve and resource statement. Highlights include:

• Total attributable proven and probable gold reserves decreased by 11% or 1.2 million ounces (after depletion) to 10.1 million ounces of gold at the end of 2013 mainly impacted by Rosebel (-1.4 million ounces) as a result of mining parameter changes reflecting higher costs associated to hard rock mining and Sadiola (-0.7 million ounces) due to change in gold price assumptions used, partially offset by an increase at Essakane (+0.8 million ounces) due to positive drilling results.  The weighted average grade of the proven and probable mineral reserves has increased from 1.1 g/t Au to 1.2 g/t Au.
  
  
• Total attributable measured and indicated gold resources (inclusive of reserves) increased by 4% or 0.8 million ounces at 23.4 million ounces of gold at the end of 2013 mainly due to the addition of Boto (+1.1 million ounces) and Essakane (+0.6 million ounces) as a result of positive drilling results, partially offset by Rosebel (-0.3 million ounces) due to mining parameter changes in pits, reflecting the higher costs associated with harder rock mining and Sadiola (-0.5 million ounces) due to change in gold price assumptions used.  The weighted average grade of the proven and probable mineral resources remained at 1.1 g/t Au.
  
  
• The niobium probable mineral reserves have decreased by 3% to 1,707 million kilograms of contained Nb₂O₅ based on the block caving scenario.
  
  
• Niobium measured and indicated resources have increased by 3% to 2.7 billion kilograms of contained Nb₂O₅ compared to the prior year.

Steve Letwin, President and CEO of IAMGOLD, said, "Amidst a $125 million company-wide cost reduction program that included a $41 million cut to the exploration plan for the year, the exploration and mine site geology teams made remarkable progress on a number of fronts.  The attributable probable mineral reserves at Essakane increased by 25% after depletion from 3.3 to 4.1 million ounces, as additional resources were found at depth and laterally in the mine pit and the model reflected more continuity in some zones.  In addition, the average grade of the mineral reserves at Essakane increased from 1.00 to 1.12 g/t Au.  The Westwood mineral reserves increased by over 40% from 348,000 to 510,000 ounces from a positive conversion of mineral resources, which also saw a net increase as a result of a successful 2013 drilling campaign.

"On the greenfield front, a maiden resource was declared on July 29, 2013 at the Boto project in Senegal, in close proximity to some of our exploration interests in Mali.  We are also excited about the progress to date and the work underway at the Pitangui Project in Brazil with a delineation drilling program advancing the project towards an initial mineral resource estimate.  Several new option agreements have also been reached with exploration companies with promising projects in regions such as Colombia and in Canada.  Although early stage, these projects present drill ready targets with potentially short time lines to discovery and reflect the hard work of our exploration team to continue to identify and build a pipeline of growth opportunities."

On January 22, 2013, the Company announced an updated NI 43-101 compliant resource estimate for the C�t� Gold deposit in Ontario comprising indicated resources of 269 million tonnes, averaging 0.88 g/t Au for 7.61 million ounces and inferred resources of 44 million tonnes, averaging 0.74 g/t Au for 1.04 million ounces. The updated resource estimate, based on a cut-off grade of 0.30 g/t Au, represents a 114% increase in indicated resources in comparison to the previous estimate announced October 4, 2012.

NIOBIUM

In 2013, more than 14,800 metres of underground Diamond drilling were completed as part of the expansion program with the objective to increase the confidence of the resources and support a five-year transition strategy towards the planned expansion of the operation. Results were as expected. In addition, over 6,900 metres of surface exploration and condemnation drilling were completed to acquire further geological and geotechnical information to assist in the design of planned mine development and surface infrastructure. The drilling programs ended in late August. Metallurgical test work was carried out continuously during the year to confirm estimated recoveries as part of the resource estimation process.

As of December 31, 2013, based on the block caving scenario, the niobium probable mineral reserves were 1.7 billion kilograms of contained Nb₂O₅ and the measured and indicated resources increased from 2.56 to 2.65 billion kilograms.

RARE EARTH ELEMENTS

As amended on September 19, 2013, IAMGOLD announced an indicated resource or 531.4 million tonnes at an average grade of 1.64% Total Rare Earth Oxides ("TREO") and inferred resource of 527.2 million tonnes at an average grade of 1.83% TREO estimated on the rare earth elements ("REE") zone located adjacent to and one kilometre north of its Niobec niobium mine.  There were no changes made in 2013 to the estimated mineral resources previously announced.

Notes to Investors Regarding the Use of Resources

Cautionary Note to Investors Concerning Estimates of Measured and Indicated Resources
This news release uses the terms "measured resources" and "indicated resources". We advise investors that while those terms are recognized and required by Canadian regulations, the United States Securities and Exchange Commission (the "SEC") does not recognize them. Investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into reserves.

Cautionary Note to Investors Concerning Estimates of Inferred Resources
This news release also uses the term "inferred resources". We advise investors that while this term is recognized and required by Canadian regulations, the SEC does not recognize it. "Inferred resources" have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. Investors are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally mineable.

Scientific and Technical Disclosure
IAMGOLD is reporting mineral resource and reserve estimates in accordance with the CIM guidelines for the estimation, classification and reporting of resources and reserves.

Note: Mineral reserves and mineral resources for IAMGOLD's gold mines for the 2013 year-end statement were estimated using a $1,400 per ounce gold price (unless otherwise indicated in the notes in Table 1) for mineral reserves and a $1,500 per ounce price for mineral resources (unless otherwise indicated in the notes in Table 1).  For open pit operations, gold resources are constrained within an economic pit shell. 

Note: Mineral reserves have been estimated as at December 31, 2013 using the block caving scenario using $45 per kg of Niobium and include dilution material. Mineral resources have been estimated using a cutoff of 0.20% Nb₂O₅ per tonne (before recovery) under the block caving scenario.

Cautionary Note to U.S. Investors
The SEC limits disclosure for U.S. reporting purposes to mineral deposits that a company can economically and legally extract or produce.  IAMGOLD uses certain terms in this news release, such as "measured," "indicated," or "inferred," which may not be consistent with the reserve definitions established by the SEC.  U.S. investors are urged to consider closely the disclosure in the IAMGOLD Annual Reports on Forms 40-F. You can review and obtain copies of these filings from the SEC's website at http://www.sec.gov/edgar.shtml or by contacting the Investor Relations department.

The Canadian Securities Administrators' National Instrument 43-101 ("NI 43-101") requires mining companies to disclose reserves and resources using the subcategories of "proven" reserves, "probable" reserves, "measured" resources, "indicated" resources and "inferred" resources. Mineral resources that are not mineral reserves do not demonstrate economic viability.

A mineral reserve is the economically mineable part of a measured or indicated mineral resource demonstrated by at least a preliminary feasibility study. This study must include adequate information on mining, processing, metallurgical, economic and other relevant factors that demonstrate, at the time of reporting, that economic extraction can be justified. A mineral reserve includes diluting materials and allows for losses that may occur when the material is mined. A proven mineral reserve is the economically mineable part of a measured mineral resource demonstrated by at least a preliminary feasibility study. A probable mineral reserve is the economically mineable part of an indicated, and in some circumstances, a measured mineral resource demonstrated by at least a preliminary feasibility study.

A mineral resource is a concentration or occurrence of natural, solid, inorganic material, or natural, solid fossilized organic material including base and precious metals in or on the Earth's crust in such form and quantity and of such a grade or quality that it has reasonable prospects for economic extraction. The location, quantity, grade, geological characteristics and continuity of a mineral resource are known, estimated or interpreted from specific geological evidence and knowledge. A measured mineral resource is that part of a mineral resource for which quantity, grade or quality, densities, shape and physical characteristics are so well established that they can be estimated with confidence sufficient to allow the appropriate application of technical and economic parameters, to support production planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough to confirm both geological and grade continuity. An indicated mineral resource is that part of a mineral resource for which quantity, grade or quality, densities, shape and physical characteristics can be estimated with a level of confidence sufficient to allow the appropriate application of technical and economic parameters, to support mine planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough for geological and grade continuity to be reasonably assumed. An inferred mineral resource is that part of a mineral resource for which quantity and grade or quality can be estimated on the basis of geological evidence and limited sampling and reasonably assumed, but not verified, geological and grade continuity. The estimate is based on limited information and sampling gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes. Mineral resources which are not mineral reserves do not have demonstrated economic viability.

Investors are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally mineable.
A feasibility study is a comprehensive technical and economic study of the selected development option for a mineral project that includes appropriately detailed assessments of realistically assumed mining, processing, metallurgical, economic, marketing, legal, environmental, social and governmental considerations together with any other relevant operational factors and detailed financial analysis,  that are necessary to demonstrate at the time of reporting that extraction is reasonably justified (economically mineable).  The results of the study may reasonably serve as the basis for a final decision by a proponent or financial institution to proceed with, or finance, the development of the project.  The confidence level of the study will be higher than that of a Pre-Feasibility Study.

A Pre-Feasibility Study is a comprehensive study of a range of options for the technical and economic viability of a mineral project that has advanced to a stage where a preferred mining method, in the case of underground mining, or the pit configuration, in the case of an open pit, is established and an effective method of mineral processing is determined. It includes a financial analysis based on reasonable assumptions on mining, processing, metallurgical, economic, marketing, legal, environmental, social and governmental considerations and the evaluation of any other relevant factors which are sufficient for a qualified person, acting reasonably, to determine if all or part of the Mineral Resource may be classified as a Mineral Reserve.
