DUGALD RIVER
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 of the
trial continue to be analysed in parallel with a review of surface infrastructure and processing requirements.
As a result of the trial stoping program, there are ore stockpiles at Dugald River of approximately 450,000
tonnes with an average grade of 13.3% zinc. Trucking this stockpiled ore to Century for processing is one of
a number of options being considered in the short term while the analysis of the trial stoping program is
underway.
