IAMGOLD Confirms Significant Gold Discovery Exceeding
Initial Targets at Saramacca - Strategically Located Near its Rosebel Gold Mine
TSX: IMG NYSE: IAG
TORONTO, Sept. 5, 2017 /CNW/ - IAMGOLD Corporation
("IAMGOLD" or the "Company") today announced the first mineral resource estimate in accordance with the Canadian
Institute of Mining, Metallurgy and Petroleum ("CIM") Definition Standards incorporated by reference in National Instrument
43-101 ("NI 43-101") for the Saramacca deposit located approximately 25 kilometres from its Rosebel operation in Suriname
(see attached map).
The resource estimate comprises 14.4 million tonnes of
indicated resources averaging 2.20 grams of gold per tonne for 1,022,000 ounces and 13.6 million tonnes of inferred resources
averaging 1.18 grams of gold per tonne for 518,000 ounces. Approximately 60% of the resources are contained within shallow,
softer laterite and saprolite hosted mineralization. The Saramacca deposit remains open along strike in both directions
and at depth and has significant potential for expansion.
IAMGOLD's President and CEO, Steve Letwin, commented, "The
NI 43-101 maiden resource estimate for Saramacca confirms the significance of this gold discovery, and adds to the substantial
resource increase reported at Rosebel just over a month ago. With an estimate surpassing our expectations and a deposit that remains
open, our transformative strategy to consolidate prospective land packages around Rosebel continues to add significant value for
IAMGOLD shareholders."
Craig MacDougall, Senior Vice President, Exploration for IAMGOLD,
stated, " The initial resource estimate reported for the Saramacca deposit today is the culmination of an outstanding effort
by our exploration and support teams, who have worked tirelessly to advance the project since the commencement of exploration activities
last September. These initial results not only exceed our expectations, but we are excited about the potential to further expand
the current resources and to make additional discoveries on the property. I congratulate the exploration team for the well-executed
and safely-completed exploration program leading to today's announcement."
The mineral resource for the Saramacca deposit incorporates
assay results from 307 diamond and reverse circulation drill holes spaced at approximately 50 x 50 metres and totalling approximately
47,000 metres, including 217 holes totalling 37,700 metres completed by IAMGOLD. The estimate was prepared using a block
model constrained with 3D wireframes of the principal mineralized domains. Values for gold were interpolated into blocks
using ordinary kriging (OK). An open pit optimization algorithm was run on the block model to constrain the resource and
to support the CIM requirement that Mineral Resources have 'reasonable prospects for eventual economic extraction'. The resource
estimate assumes a long-term gold price of US$1,500/ounce. Only mineralization contained within the preliminary pit shell has been
included in the resource estimate. It is meaningful to note that the pit shell generated extends to the base of the defined
resources in some of the higher grade zones of the deposit. The effective date of this resource estimate is August 28, 2017.
A supporting NI 43-101 Technical Report will be filed on SEDAR
at www.sedar.com no later than 45 days after the date of this release.

Notes: |
|
1. |
Mineral resources are not mineral reserves and have not demonstrated economic viability. |
2. |
CIM definitions were followed for classification of Mineral Resources. |
3. |
Cut-off grades are 0.25 g/t Au for laterite and saprolite, 0.35 g/t Au for transition and 0.45 g/t Au for fresh rock. |
4. |
Mineral Resources are reported using a gold price of US$1,500 per ounce. |
5. |
Mineral Resources are constrained by a Whittle optimized pit shell. |
6. |
All figures have been rounded to reflect the relative accuracy of the estimates. Discrepancies in sums occur due to rounding. |
In support of the mineral resource estimate, preliminary metallurgical
test work was completed by ALS Metallurgical Laboratories in Vancouver, British Columbia, Canada, on thirteen composite samples
prepared from drill core obtained from the Saramacca drilling program. The results suggest that gold recoveries averaging approximately
97% in oxide, 76% in transition and 82% in fresh rock can be expected from a conventional gravity and leach/carbon in leach (CIL)
circuit. Further testing is recommended to further optimize gold recoveries.
About the Saramacca Project
The Saramacca project is strategically located approximately
25 kilometres southwest of the Rosebel Gold Mine processing facility. Mineralization is hosted in the Paramaka Formation within
the lower part of the Marowijne Greenstone Belt, which is dominated by metamorphosed basalt and andesite lithologies in the project
area. These are traversed by the regional, northwest trending Saramacca shear zone, an important deformation zone for the
localization of gold mineralization. Drilling has confirmed the presence of multiple mineralized structures within an approximately
2-kilometre long and 400-metre wide corridor. Mineralization occurs in the near surface oxidized weathering profile to depths ranging
from 50 to 100 metres, as well as deeper in primary sulphide zones. In the deposit area, three mineralization styles are
recognized from the drilling completed to date: breccia hosted mineralization characterized by jigsaw, crackle and matrix supported
breccias; shear hosted mineralization characterized by well-developed pyritic disseminations and stringers; and irregular pyrite-quartz-carbonate
veins which locally carry high gold grades.
On August 30, 2016, the Company signed a letter of intent
with the Government of Suriname to acquire rights to the Saramacca property, with the intent of defining a National Instrument
43-101 mineral resource within 24 months. The terms of the letter included an initial payment of $0.2 million, which enabled immediate
access to the property for Rosebel's exploration team to conduct due diligence, as well as access to the data from previous exploration
activity at the Saramacca property. On September 30, 2016, having been satisfied with the results of the due diligence, the Company
ratified the letter of intent to acquire the Saramacca property and subsequently paid $10 million in cash and agreed to issue 3.125
million IAMGOLD common shares to the Government of Suriname in three approximately equal annual instalments on each successive
anniversary of the date the right of exploration was transferred to Rosebel (December 2016). In addition, the agreement provides
for a potential upward adjustment to the purchase price based on the contained gold ounces identified by Rosebel in National Instrument
43-101 measured and indicated resource categories, within a certain Whittle shell within the first 24 months, to a maximum of $10
million.
The Saramacca project falls within the "UJV" area
as defined in an Agreement with the Government of Suriname announced on April 15, 2013. The Agreement establishes a joint
venture growth vehicle under which Rosebel would hold a 70% participating interest and the Government will acquire a 30% participating
interest on a fully-paid basis.
Next Steps
With the results of the initial resource estimate now in hand,
a follow up drilling program is expected to commence this quarter with the objective to: 1) increase the confidence in the current
resources and convert inferred resources to indicated; 2) target expansions to the existing resource along known mineralized trends
and at depth, and 3) evaluate identified exploration targets for the presence of additional mineralized zones. A program
of approximately 20,000 metres of diamond and reverse circulation drilling is planned for completion during the remainder of 2017.
In addition to the drilling program outlined above, the Rosebel
mine team is working to advance the Saramacca deposit towards production. An Environmental and Social Impact Study (ESIA)
is already underway as the fundamental element in the permitting process. Preliminary engineering work has been undertaken
on mine design, and infrastructure elements such as ore transport options, access roads, and waste rock disposal. In addition
to the exploration work planned for the next phase, field work will commence soon on geotechnical investigation and condemnation
work. Additional, comprehensive metallurgical testing will also be undertaken to refine the recovery assumptions, to test
the crushing and grinding characteristics of the ore, and to investigate the metallurgical variability across the ore deposit.
Using the new block model as a basis, new mine designs and integrated scheduling with the main Rosebel resources will commence
soon, and will continue to be advanced as additional geologic and engineering information becomes available. It is our intention
to complete the permitting work and to generate a preliminary reserve estimate for Saramacca during the first half of 2018 and
to work toward initial production in 2019.

Notes to Investors Regarding the Use of Resources
Cautionary Note to Investors Concerning Estimates of Measured
and Indicated Resources
This news release uses the term "indicated resources". We advise investors that while that term is 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 estimates in accordance with the CIM guidelines for the estimation, classification and reporting
of resources.
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 resource 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' 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 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.
