Macraes Gold Mine, Waitaki District, New Zealand

Macraes gold mine is situated 2km east of Macraes township in the Waitaki District of Otago New Zealand The mine site extends across 15,705ha and includes surface operation of 55 million tonnes per annum (Mtpa), underground mine of 1Mtpa, and a processing plant Spanning across an area of 26,685ha, the company’s mining and explorationThe Macraes processing plant treats various ore sources from underground and open pits within the Macraes gold mine, as well as concentrate from the Reefton gold mine on the West Coast of NZOptimisation of metallurgical plant sampling procedures atGold at Macraes is known as ‘refractory ore’, which means it is ultrafine and resistant to the typical cyanide leach process, typical of most gold processing plants This refractory nature of the ore led to inefficiencies recovering the gold from ore in the past The ore now goes through a threestage processing cycle to ensure the gold is economically recovered from the oremacraes gold processing plant ikonacoffeecz
