Dugald River

The Dugald River project is one of the largest and highest-grade known undeveloped deposits of zinc, lead and silver in the world. Located in north-west Queensland, approximately 65 kilometres north-west of Cloncurry, the deposit is a Mineral Resource of 63 million tonnes at 12% zinc, 1.8% lead and 31g/t silver.

The project is an underground development accessed by two declines (north and south).

A mine stoping trial is being conducted throughout 2014 to determine the accurate stope design parameters and productivity assumptions for Dugald River leading up to the assessment of future options for the project.

As at the third quarter 2014, a total of 13 out of 22 trial stopes had been successfully mined and backfilled. Stope spans between 15m and 30m have proven stable for the geotechnical conditions encountered, and a geological and geotechnical program is now underway to review the findings in relation to the entire ore body.

Processing Dugald River ore using existing infrastructure at Century mine remains a future option for the project.
