A Gold Mine in Russia owned by
Petropavlovsk
. The Pioneer mine now consists of five main open pits: Yuzhnaya, Promezhutochnaya, Bakhmut, Andreevskaya and north-east Bakhmut with four being actively mined this year. The north-east Bakhmut pit was commissioned in 2010 and contributed considerably to the production for the year.
Ore at Pioneer is processed at the on-site 5.0Mtpa RIP plant, which consists of three processing lines: one 5.5m x 1.8m SAG mill, one 3.2m x 5.4m ball mill and a sorption and desorption circuit with 200m3 tanks, and two larger processing lines consisting of two 7.5m x 2.5m SAG mills, four 4.0m x 6.0m ball mills and a sorption and desorption circuit with 450m3 tanks. The Group is planning to commission a flotation unit at the plant in 2013/14 to process refractory ores simultaneously with direct cyanidation leaching and to ship the resultant flotation concentrate to the POX plant that will be constructed at the nearby Pokrovskiy mine for further processing and recovery of gold.
