IAMGOLD Corporation provided a further update from its 2018 drilling program completed at its Nelligan joint venture project (IAMGOLD Corporation: 51%, Vanstar Mining Resources Inc. ("Vanstar"): 49%), located 60 kilometres southwest of Chibougamau, Quebec, Canada. The Company is reporting assay results from the remaining nine (9) diamond drill holes totaling 4,487 metres completed as part of the 2018 drilling program. The 2018 diamond drilling program was designed to evaluate the resource potential of the recently discovered mineralization system, referred to as the Renard Zone, located immediately north of the previously known Liam and Dan zones. The drilling program continued to intersect wide zones of hydrothermal alteration characterized by variable carbonatization, sericite, phlogopite and pervasive silicification affecting the hosting meta-sedimentary sequence. Disseminated pyrite is widespread, distributed in the alteration zones and varies from 1% to locally 15%. Trace molybdenite and occasionally fine grains of visible gold are observed. In 2019, an initial 12,000 to 15,000 metres of diamond drilling program is planned to infill and further test continuity of the mineralized zones of the Renard system. Drill rigs are currently being mobilized to the property with the commencement of drilling activities expected by mid-January. The drilling results, coupled with ongoing geological, geochemical and structural studies, will be integrated to support the development and refinement of a deposit model with the objective of completing an initial NI 43-101 compliant resource estimate in 2019.
