The Hera operation is comprised of the Hera (Pb-Zn-Au-Ag) and Nymagee (Cu-Ag) deposits. Aurelia Metals (formerly YTC Resources) commenced box cut and decline development at Hera in 2012. First production from Hera commenced in the September quarter of 2014. Pre-feasibility study on Nymagee deposit is still ongoing in 2018, and thus has not been included in the accompanying analysis. Wood Mackenzie’s asset reports are built from the bottom up, incorporating a number of granular data metrics to ultimately produce our industry standard cash operating costs. This report contains a detailed asset note giving you a holistic view of the asset, including an operational overview through to a timeline of events from inception to now. This qualitative analysis is supplemented by the associated Excel download which enables interrogation of a whole series of cost and production metrics over the life of the asset.
