Report summaryLaRonde is one of the deepest mines in the Western Hemisphere with its 2.2km deep Penna Shaft. Underground production is from the LaRonde and El Coco properties, using a combination of longitudinal retreat and transverse open stoping mining methods. Processing is relatively straightforward with grinding, differential flotation - copper/lead flotation and separation, zinc flotation and zinc tailings precious metals leaching circuits followed by carbon-in-leach (CIL) recovery. Mine life is estimated at 8 years until 2024, with the possibility of a further 2 year extension with production from LaRonde Zone 5. In 2016, payable production totalled 306koz Au, 988koz Ag, 4.7kt Zn and 4.4kt Cu.
