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).

MMG conducted a trial stoping program in 2014 to determine the geotechnical conditions and practical operating performance of the underground mine.

The mining component of this program is now complete with 19 stopes successfully mined, providing valuable input into the determination of the optimal stope size and project parameters. The results have been analysed in parallel with a review of surface infrastructure and processing requirements. A decision on Dugald River will be made in the third quarter of 2015.

As a result of the trial stoping program, there is an ore stockpile at Dugald River of approximately 450,000 tonnes with an average grade of 13.3% zinc. A trucking program of this stockpiled ore to Century (Lawn Hill) for processing is underway and will be completed by 30 November 2015.

Find out more about the trucking program along with tips on sharing the road safely with heavy vehicles when travelling in the Gulf of Carpentaria.
