New Century Resources Limited provide an update on Century production and operational ramp up during the Q1 2019. During the quarter the operations continued the successful ramp up of plant performance, with total zinc recoveries averaging 50% for March 2019 and peaking at 54% (86% of the design target). The improved plant performance resulted in a 50.4% increase in total metal production from operations, with 18,170t of zinc metal produced in 37,500 tonne of concentrate grading 48.3% zinc (vs 25,500t at 47.0% zinc Q4 2018). Silver content of 152g/t within the concentrate remained in line with previous quarter operations.

The quality of zinc concentrate produced also continued to improve significantly over the quarter, with a 25% decrease in the lead impurity content (5.6% Pb for March 2019 vs 7.5% Pb Q4 2018). Silica content remained within the target range of 5.0-7.5% Si02 (6.9% Si02 average for the quarter).

While hydraulic mining operations maintained two cannons in operation for Q1 2019, wet season effects and mining of marginally lower grade zones of the tailings dam caused an 8% reduction in overall zinc metal mined (1.39 million tonne at 2.92% Zn Q1 2019 vs 1.5 million tonne at 2.95% Zn Q4 2018). Despite this decrease in total metal mined, the operations still achieved an increase in metal production of over 50%, further demonstrating the significance in improvement of plant metallurgical performance.

Post quarter end the installation of a third mining cannon and pumping system was completed, resulting in ability for the operations to target ramp up to a mining rate consistently above 8.0Mtpa and up to 10 million tonne per annum during Q2 2019.
