IAMGOLD REPORTS NEW DISCOVERY WITH HIGH GRADE DRILL
INTERSECTIONS FROM ITS 2019 DRILLING PROGRAM ON THE
KARITA PROJECT IN GUINEA
Toronto, Ontario, October 2, 2019 – IAMGOLD Corporation (“IAMGOLD” or the “Company”) today
announced assay results from its 2019 drilling program on its wholly owned Karita project in North-Eastern
Guinea. The project is strategically located along the prolific Senegal - Mali Shear Zone in West Africa,
between the Company’s Boto Gold Project in Senegal to the north, and its Diakha -Siribaya project in Mali
to the south. The Company is reporting assay results from 16 reverse circulation (RC) drill holes totaling
1,839 metres completed as part of its 2019 exploration program.
The assay results reported herein are provided in Table1 below and include the following highlights (a drill
hole plan map and drill section is attached to this release):
2019 RC Drill results:
Drill hole KRC19-001: 13.0 metres grading 2.80 g/t Au
and 16.0 metres grading 2.41 g/t Au
includes 3.0 metres grading 9.84 g/t Au
Drill hole KRC19-006: 29.0 metres grading 2.96 g/t Au
includes 10.0 metres grading 3.52 g/t Au
Drill hole KRC19-009: 16.0 metres grading 3.17 g/t Au
includes 8.0 metres grading 5.61 g/t Au
and 32.0 metres grading 1.83 g/t Au
Drill hole KRC19-010: 22.0 metres grading 2.27 g/t Au
includes 5.0 metres grading 5.54 g/t Au
Drill hole KRC19-011: 21.0 metres grading 9.01 g/t Au
Includes 7.0 metres grading 25.67 g/t Au
and 7.0 metres grading 2.90 g/t Au
Craig MacDougall, Senior Vice President, Exploration for IAMGOLD, stated, " we are very pleased to
announce these drilling results which confirms a new grassroots exploration discovery along this portion of
the Senegal – Mali Shear Zone. As with our previous discoveries at the Boto Gold Project, located 8
kilometres to the north, and at the Diakha-Siribaya Project, located 3 kilometres to the south, we have
intersected multiple, wide zones of mineralization within altered metasedimentary units. With now our third
grassroots discovery we continue to highlight the outstanding exploration potential along this portion of the
shear zone. Once again, I want to recognize the efforts of our exploration team in West Africa and
congratulate them on their newest discovery.”
About the Karita Project
The Karita project is wholly owned by IAMGOLD and is held under an exploration permit that covers
approximately 99.85 square kilometres, located in the Birimian aged Kédougou-Kéniéba inlier of the West
African Craton region along the borders with Senegal and Mali.
In 2017, the Company completed a reconnaissance geology and termite mound geochemical sampling
program over the Karita permit to evaluate the interpreted extension of the Boto-Diakha mineralized trend
in Guinea. The area is thought to cover an extension of the regionally important and prolific Senegal - Mali
shear zone along trend between IAMGOLD’s Boto Gold Project in Senegal to the north, and its Diakha-
Siribaya Project in Mali to the south. The sampling program identified an extensive gold geochemical
anomaly delineated over a nearly two kilometer strike length, and similar to that observed to be associated
with the deposits occurring at both Boto and Diakha.
The 2019 drilling program was designed to evaluate the geochemical anomaly for the presence of
mineralization and involved the completion of wide spaced lines of RC drilling over a 1.6 kilometre strike

length of the anomaly. The program has confirmed the presence of multiple zones of wide inter vals of
mineralization hosted within an albite + hematite + carbonate altered sandstone metasedimentary unit.
The style of the mineralization and associated alteration appears similar to IAMGOLD’s other deposits in
the region.
Next Steps
The results of this drilling program will be compiled and integrated with data from our adjacent Boto and
Diakha-Siribaya projects to help guide future drilling programs with an objective to define the extents of the
mineralization and evaluate the resource potential of this new discovery. The program will include twinning
RC holes with diamond holes to confirm the widths and orientation of mineralized intervals and help
establish the structural and geological characteristics of the mineralizing system.
Technical Information and Quality Control Notes
The drilling results contained in this news release have been prepared in accordance with National
Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101").
The “Qualified Person” responsible for the supervision of the preparation, verification, and review of the
technical information in this news release is Konan Barthelemy Kramo, P. Geo, Project Manager, Mali
Exploration. Mr. Kramo is a Qualified Person as defined by National Instrument 43 -101.
The information in this news release was reviewed and approved by Craig MacDougall, P.Geo., Senior
Vice President, Exploration for IAMGOLD. Mr. MacDougall is a Qualified Person as defined by National
Instrument 43-101.
The sampling of, and assay data from, RC chips are monitored through the implementation of a quality
assurance - quality control (QA-QC) program designed to follow industry best practice and include the
insertion of certified reference standards. Rock chips from the Reverse Circulation drilling are collected at
the rig site, at one meter intervals, under the direct supervision of IAMGOLD geologists and field
technicians. Samples are riffle split to obtain two 3 kg samples. One sample is retained for reference
purposes and the other sample is sent for assay.
The assay samples were prepared at Bureau Veritas in Bamako, Mali and assayed at Bureau Veritas
Analytical Laboratory in Abidjan, Ivory Coast, using a standard fire assay with a 50-gram charge and an
Atomic Absorption finish (FA450). Samples which returned values greater than 10 g/t Au are being re-
assayed using a gravimetric finish.

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 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 “will”, “should”,
“continue”, “expect”, “anticipate”, “estimate”, “believe”, “intend”, “to earn”, “to have’, “plan” or “project” or the negative of
