IAMGOLD Reports New Discovery with High Grade Drill Intersections from Its 2019 Drilling Program on the Karita Project in Guinea

Oct 02, 2019

Toronto, Ontario--(Newsfile Corp. - October 2, 2019) - IAMGOLD Corporation (TSX: IMG) ("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 intervals 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.

Forward Looking Statement

1. The true widths of intersections are unknown at this time, but are interpreted to approximate the reported downhole lengths.
2. Drillhole intercepts are calculated using a minimum downhole length of two (2) meters, a cut-off grade of 0.5 g/t gold, and may include up to two (2) metres of internal dilution.
3. Assay intervals are reported uncapped, with higher grade subintervals reported if present.
