| ABSTRACT: | Toronto, Ontario, November 6, 2019 – IAMGOLD Corporation (“IAMGOLD” or the “Company”) today announced positive results from a Feasibility Study ("FS") for the Carbon-in-Leach and Heap Leach Project (the “Project”) at its Essakane operation in Burkina Faso, West Africa. The results support an increase in current hard rock carbon-in-leach (“CIL”) plant capacity and outlines an economically viable Heap Leach (“HL”) facility at the end of CIL operations. The FS concluded that increasing CIL plant capacity and postponing the HL operation to the end of LOM defers capital and provides an extension to the life of mine. Optimization work focused on increasing CIL throughput to 11.7 Mtpa (at 100% hard rock equivalent capacity) compared to the current design at 10.8 Mtpa (at 100% hard rock equivalent capacity) with minimal capital of $9 million. The optimization of the CIL plant would indirectly result in a reduction of the anticipated HL annual throughput from 10.0 Mtpa to 8.5 Mtpa. The production profile of the HL operation remains relatively unchanged as reduced throughput is offset by an improved recovery of gold in HL from 55.0% to 67.0%. The capital cost of the HL facility was reduced by $40M, for the new scenario, by re-using existing CIL plant equipment (primary & secondary crushing circuits) at the end of CIL life and by optimizing the Heap Leach Pad footprint. The optimization of the Heap Leach Pad footprint allows for the HL infrastructure to remain within the current industrial complex of the mine, versus the PFS scenario which would have required additional land outside of the current complex, thus avoiding impact to communities and farmland. | |
