The Pb step-leaching routine presented here is derived from the unpublished intellectual property of J. Hergt, J. Woodhead, and M. Tonelli (The University of Melbourne). Without their effort, this work would not have been possible. Work here forms part of RJD's PhD within the pmd*CRC (Predictive Minerals Discovery Cooperative Research Centre) with support from Xstrata Copper, and this paper is published with permission. We acknowledge the help of S. McKnight for his help with the epidote imaging. G. Mark, I. Buick, R. Frei, and C. Ballhaus are thanked for providing helpful comments on this manuscript.
