Operation of the slurry pipeline marks another milestone for New Century, with saleable zinc concentrate produced on site undertaking the first stage of logistics for export.
Pumping slurry to Karumba also moves New Century closer to that all important revenue cheque.
The slurry pipeline is 304km long. Slurry is moved along the pipeline thanks to three Wirth pumps.
As part of the Century operations New Century is upgrading the flotation plant, the 700-person camp, airport, grid power connection, port facility and concentrate transhipment vessel.
New Century aims to become one of the world's top-10 zinc producers.
