Study Maps Future Path for Frieda River Project

PanAust Ltd. has reported the results of a new feasibility study of the Frieda River copper-gold project in Papua New Guinea that contemplates initial development of a large open-pit operation based on approximately one-quarter of the project’s resources. Plant feed to a conventional processing plant would average about 40 million mt/y to produce averages of 175,000 mt/y of copper and 250,000 oz/y of gold in concentrate over a mine life of 17 years.

OZ Finds New High-grade at Prominent Hill

An OZ Minerals drilling program on the eastern end of its Prominent Hill orebodies in South Australia has returned strong results, including a 68.5-m intercept grading 3.2% copper and 0.5 g/mt gold located 40 m east of previous domain interpretation and outside of the existing classified mineral resource. OZ Minerals is spending $4 million in 2016 on a diamond drill program to increase the confidence level of the mineralization by infill drilling to a vertical depth of 700 m below surface, testing its potential for future conversion to ore reserves.
