Final deliveries of the mills, high-pressure-grinding rolls (HPGR), flotation cells and thickeners are expected in August. At the Platreef tier-one, palladium-platinum-nickel-copper-gold-rhodium project in South Africa, the project's first shaft (Shaft 1) has been completed to a final depth of approximately 996 metres.

HPGR creates a finer particle size, which helps to liberate the gold particles, resulting in increased recoveries. An improved understanding of the leaching process on its low-grade ore and the potential of this cost-effective grinding addition provided it with the confidence to continue heap leaching beyond the short-term time horizon ...
