New Century Resources has recorded a 28 per cent increase in zinc metal output during the September quarter as it continues the ramp-up at Century mine.
It produced 26,171 tonnes of zinc metal in 53,500 tonnes of concentrate for the quarter through the lower Gulf region tailings reprocessing operation.
Its main focus has been upgrading the cleaner circuit within the processing plant, removing bottlenecks for continued recovery improvement and increasing metal production.
New Century said the upgrade was delivered on schedule and budget in mid-August, providing a step-change improvement in operational performance for the second half of the September quarter.
“The improvements due to this upgrade are particularly evident in the performance during the month of September, which delivered 10,013t of zinc metal at an average recovery of 52 per cent zinc (against an overall quarterly average recovery of 48 per cent zinc),” the company reported.
Operations have become more consistent, with more than 50 per cent zinc recovery now achieved for more than 30 days straight.
The average mining rate also improved and is now being progressively increased to 9Mtpa over the course of the December quarter.
New Century said it expected further improvements to metallurgical recoveries and metal production rates during FY20, through the planned expansion to 12Mtpa plant capacity.
