Dugald River set to step up another level
General manager Sam Rodda said the MMG site would aim for an ore throughput as high as 2Mtpa and was still ramping up its underground mining operations with contract partner Barminco.
“It’s exciting for us. We still don’t totally understand what the ultimate capacity is for mining this site,” he said.
“Part of our challenge and opportunity is to find our right sustainable production rate.”
The MMG-owned Dugald River mine and processing operation, 65km north-west of Cloncurry, came online in late 2017.
In its first full calendar year of operation it achieved an output of 147,320 tonnes of zinc in zinc concentrate and just under 17,000 tonnes of lead in lead concentrate.
It produced 38,665 tonnes of zinc in zinc concentrate in the first quarterof this year.
“Over the last 12 months, pleasingly, we’ve been able to optimise how the plant runs and steadily improve mine production and, even with some of the flood interruptions, we’ve been able to maintain really strong production in the first quarter (of 2019),” Mr Rodda said.
“We reached design capacity for the processing circuit last year in a record rate.
“We’re able to process targeted metal at 1.75Mtpa and we reached those targets by the back end of 2018.
“We will continue to try to optimise the plant to see if we have the ability to extend that to 1.8 million, 1.9 million, 2Mtpa.
“That’s going to be part of our project opportunity over this year, to see how we can get more out of our processing plant through efficiencies and less downtime on the equipment and working with the team to identify little business improvement opportunities along the way.”
Underground, the Dugald River team is looking to increase the number of production levels it has on the go to consistently achieve a throughput rate of 1.8Mtpa by the end of the year.
