OZ Minerals has initiated a scoping study of the potential for mining startup at its Carrapateena underground copper-gold project in South Australia based on extraction of the deposit’s high-grade core. The study was prompted by a new analysis of the core that identified 61 million metric tons (mt) of resources grading 2.9% copper equivalent (2.4% copper, 0.9 g/mt gold, and 11.7 g/mt silver). An earlier prefeasibility study released in August 2014 was based on much larger indicated and inferred resources totaling 800 million mt and grading 0.8% copper and 0.3 g/mt gold.
