Petropavlovsk’s operational assets include three mines; Pioneer, Albyn and Malomir as well as known satellite deposits and the Pressure Oxidation (“POX”) Hub, a technologically-advanced plant designed to process refractory gold ores. Mining is principally undertaken as open-pit, although smaller underground mining operations exist at Pioneer and Malomir to extract deeper higher-grade ore.
Ores that are amenable to direct cyanidation are processed at on-site resin-in-pulp (“RIP”) plants located at each of the three mines. Refractory ores found at Pioneer and Malomir require two additional treatment stages, including flotation and then pressure oxidation. A 3.6Mtpa flotation plant is operational at Malomir and a similar plant was launched at Pioneer on 31 May 2021.
