Mayskoye gold mine

Report summary

Mayskoye is predominantly a high grade underground operation utilising sub-level open stoping method. The refractory ore undergoes single-stage crushing, prior to three-stage grinding (in one SAG mill and two ball mills), with the slurry then reporting to the three-stage conventional flotation circuit at the 850kt/a Mayskoye concentrator to produce gold concentrate. Due to refractory nature of the ore, concentrate was transported to Amursk pressure oxidation plant (POX-1) as well as third party off-takers for further processing and cyanidation. In 2019, Mayskoye concentrate was no longer processed at Amursk POX-1, with it now being loaded with Kyzyl concentrate and shipped to third party off-takers. In 2016, the company opted to extract the crown pillars from zones 1 & 2 utilising open-pit mining. The open pit delivered oxide and transitional ore that was processed through the Mayskoye processing plant that was retrofitted to incorporate a resin-in-leach circuit.
