Enclosure and mill delivery. In 2013 we finished most of the foundation works and most of the main buildings were enclosed. We also completed the steel structure of the accommodation building at the permanent camp, laid the foundation and erected the steel frames of the plant maintenance workshops and completed the main access road to permit transportation of the heavy equipment to the site.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
