IAMGOLD Reports Additional Positive Assay Results from the 2019 Drilling Program Completed on the Lac Gamble Zone of the Rouyn Gold Project, Quebec
Toronto, Ontario--(Newsfile Corp. - July 31, 2019) - IAMGOLD Corporation (TSX: IMG) ("IAMGOLD" or the "Company") today provided the remaining assay results from its 2019 diamond drilling program completed on the Lac Gamble Zone at the Rouyn Gold project optioned from Yorbeau Resources Inc. ("Yorbeau"). The project is located 4 km south of Rouyn-Noranda, Quebec, and approximately 45 kilometers southwest of IAMGOLD's Westwood operation. The Company is reporting assay results from the remaining 17 diamond drill holes, totaling 4,946 metres. Three (3) drill holes were abandoned due to excessive deviation and re-collared. Results for 31 diamond drill holes totaling 8,438 metres were previously reported (see news release dated May 23 and June 12, 2019).
The assay results reported herein are provided in Table 1 below and include the following highlights (a longitudinal section illustrating the drilling program on the Lac Gamble zone is attached to this news release):
- Drill hole GA-19-711: 9.7 metres grading 6.6 g/t Au
includes: 5.9 metres grading 10.0 g/t Au
- Drill hole GA-19-719: 16.9 metres grading 3.4 g/t Au
includes: 5.8 metres grading 5.7 g/t Au
includes: 1.8 metres grading 10.3 g/t Au
- Drill hole GA-19-721: 23.4 metres grading 6.1 g/t Au
includes: 8.1 metres grading 13.3 g/t Au
includes: 1.0 metres grading 65.5 g/t Au
- Drill hole GA-19-722: 10.1 metres grading 6.6 g/t Au
includes: 3.0 metres grading 10.9 g/t Au
and includes: 4.0 metres grading 7.9 g/t Au
Craig MacDougall, Senior Vice President, Exploration for IAMGOLD, stated: "We are very pleased with the positive results obtained from our first delineation drilling program completed earlier this year at Lac Gamble. The program successfully targeted mineralization in the upper part of the zone with a number of drill holes intersecting good grades over wide intervals. The zone also appears to remain open along strike to the west and at depth and therefore has potential for further expansion with additional drilling. We look forward to incorporating the results from this drilling program to develop a robust deposit model to allow for the completion of a future resource estimate. I would like to acknowledge that the success of this initial program benefited significantly from the close collaboration between the IAMGOLD and Yorbeau exploration teams."
The objective of the 2019 winter diamond drilling program was to systematically infill a portion of the Lac Gamble zone to evaluate the potential to outline a resource. The program was designed to achieve an approximate 50 x 50 metres drill hole spacing pattern. The drilling program successfully intersected the targeted sheared Cadillac-Piché corridor which hosts the mineralized zone. The zone is associated with alteration varying from several metres to greater than ten metres in width, exhibiting variable carbonatization, fuchsite, silicification, crosscut by a network of white quartz and brown tourmaline stockwork veins and breccias. Gold mineralization occurs as small specks of visible free gold associated with minor sulphides in quartz-tourmaline veinlets.
The results of this initial diamond drilling program will be compiled and integrated with the existing geological, geochemical and structural information to support the development and refinement of a preliminary deposit model. This work will be used to support the completion of a mineral resource estimation of the Lac Gamble zone currently in planning.
Drilling has also resumed to test selected exploration targets in the area of the historic Astoria deposit, located several kilometres to the east of Lac Gamble. The program will involve the completion of approximately 5,000 metres of diamond drilling and assay results will be reported once they are received, validated and compiled.
About the Rouyn Gold Project
The Rouyn Gold Property is located about 4 km south of Rouyn-Noranda, Quebec. With a long history of mining, the city of Rouyn-Noranda offers many advantages for mining and exploration, including political and social stability, good access and infrastructure, skilled mining personnel, and one of the most mining-friendly jurisdictions in the world.
The property covers a 12-kilometre stretch of the Cadillac-Larder Lake Break and contains four known gold deposits along the 6-km Augmitto-Astoria corridor situated on the western portion of the property. Two of the four deposits, Astoria and Augmitto, benefit from established underground infrastructure and have been the subject of technical reports that include resource estimates that were previously filed in accordance with Regulation NI 43-101.
The Lac Gamble zone is located between the Augmito and the Astoria deposits. The exploration target potential at Lac Gamble is interpreted to be between 400,000 and 600,000 ounces of gold at a grade between 7.0 and 8.5 g/t Au. The potential quantity and grade of the exploration targets referred to are conceptual in nature and insufficient exploration work has been completed to define a mineral resource. The property may require significant future exploration to advance to a resource stage and there can be no certainty that the exploration target will result in a mineral resource being delineated. The exploration targets are consistent with similar deposits in the area, deposit models or derived from initial drilling results.
IAMGOLD signed a definitive option agreement in December 2018, whereby IAMGOLD has the option to acquire a 100% interest in the Project by making scheduled cash payments totaling C$4 million and completing exploration expenditures totaling C$9 million over a four year period. Exploration programs must include the completion of a minimum of 20,000 metres of diamond drilling within the first two-years of the option. By the end of the expenditure period, the Company must complete a NI 43-101 compliant resource estimate, after which the Company, at its election, can purchase a 100% interest in the Project, subject to a 2% net smelter return production royalty, by paying Yorbeau the lesser of C$15 per resource ounce or C$30 million.
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.
The "Qualified Person" responsible for the supervision of the preparation and review of this information is Marie-France Bugnon, P. Geo., General Manager Exploration. Marie-France is considered a "Qualified Person" for the purposes of National Instrument 43-101 with respect to the technical information being reported on. The technical information has been included herein with the consent and prior review of the above noted Qualified Person. The Qualified person has verified the data disclosed, and data underlying the information or opinions contained herein.
The design of the drilling program and interpretation of results is under the control of IAMGOLD's and Yorbeau's geological staff, including qualified persons employing strict protocols consistent with NI 43-101 and industry best practices. The sampling of, and assay data from, the drill core is monitored through the implementation of a quality assurance - quality control (QA-QC) program. Drill core (NQ size) is logged and samples are selected by geologists and then sawn in half with a diamond saw at the project site. Half of the core is retained at the site for reference purposes. Sample intervals may vary from half a metre to one and a half metres in length depending on the geological observations.
Half-core samples are packaged and transported in sealed bags to AGAT laboratories in Val d'Or, Quebec, and Mississauga, Ontario. Samples are coarse crushed to a -10 mesh and then a 1,000 gram split is pulverized to 95% passing -150 mesh. AGAT prepare analytical pulps at their facilities located in Val-d'Or and processed the pulps at their Mississauga laboratory which is ISO / IEC 17025:2005 certified by the Standards Council of Canada. Samples are analyzed using a standard fire assay with a 50 gram charge with an Atomic Absorption (AA) finish. For samples that return assay values over 3.0 grams per tonne, another pulp is taken and fire assayed with a gravimetric finish. Core samples showing visible gold or samples which have returned values greater than 10.0 grams per tonne are processed with a protocol involving fine grinding of the entire sample, followed by metallic screen analysis of the entire pulverized material. Insertion of duplicate, blanks and certified reference standards in the sample sequence is done in all drill holes for quality control.
