The processing plant at Monument Mining’s Selinsing Gold Project can now annually treat up to 1 million tonnes of ore following completion of a major expansion. Monument says the $8 million phase 3 expansion began in September last year and finished on time and $500,000 over budget.
The works included installation of an additional crusher, a primary ball mill, three additional leach tanks and improvements to the gold room, detox circuit, tailing pipes and pumping system. It means the plant will provide necessary operating flexibility for processing blended feed when the open pit increases at depth. The company has identified extensions to the Selinsing and Buffalo Reef ore zones both along strike and down dip.
Monument also spent $1.7 million to enlarge the tailings storage facility to accommodate increased discharge from the upgraded plant during the next decade.
The Canadian gold producer says its Selinsing processing plant was successfully commissioned in July by performing at an average of more than 90% of designed capacity for more than 30 consecutive days.
Monument’s president Robert Baldock says, “We are pleased with the increased production capacity and flexibility, and very proud of our in-house Selinsing team that designed, built and commissioned the expanded process plant. The increased capacity will enable us to double the amount of ore to be processed in fiscal 2013 comparing to fiscal 2012 when the mill feed grades are expected to be lower.”
