The Dugald River zinc project in north-west Queensland is 45 per cent complete and remains on target for first concentrate production in the first half of 2018, according to owner MMG’s December quarter report.
Key milestones during the fourth quarter were 1514m of lateral development, 16,592m of diamond drilling and 209m of vertical raise bore hole development completed, the company said.
The high-voltage transmission line steel pole installation is complete with connection to grid power progressing on schedule, all new primary mine ventilation fans have been commissioned and operational, and the ball and SAG mills have been installed.
The project is expected to cost $US600-620 million (plus interest) to bring to completion.
Dugald River is positioned to be within the world’s top 10 zinc mines when operational, with an expected mine life of about 25 years.
The optimised mine plan will support a 1.7 Mtpa operation with annual production of about 170,000 tonnes of zinc in zinc concentrate, plus by-products.
