Woodlawn Zinc-Copper Project

Heron’s primary development project is the high-grade Woodlawn Zinc-Copper Project located 250km southwest of Sydney, New South Wales. The project consists of both a high-grade underground and a large medium grade tailings resource. The development approach envisages the construction of a single 1.5Mtpa processing plant capable of treating material from both sources. Planned production will see the generation of three separate base metal concentrates (zinc, copper and lead) with associated precious metal credits. In addition, the project is very well supported by excellent infrastructure, an existing mining lease and state government development approvals.

Woodlawn is expected to become an important Australian near-term zinc producer delivering concentrates into a market with strong supply and demand fundamentals underpinning a strong commodity price.

About Heron Resources

Zinc equivalent calculation – Woodlawn


The zinc equivalent ZnEq calculation takes into account, mining costs, milling costs, recoveries, payability (including transport and refining charges) and metal prices in generating a Zinc equivalent value for Au, Ag, Cu, Pb and Zn. ZnEq = Zn%+Cu%*3.12+Pb%*0.81+*Au g/t*0.86+Ag g/t*0.03. Metal prices used in the calculation are: Zn US$2,300/t, Pb US$ 2,050/t, Cu US$6,600/t, Au US$1,250/oz and Ag US$18/oz. These metal prices are based on Heron’s long-term view on average metal prices. It is Heron’s view that all the metals within this formula are expected to be recovered and sold. Metallurgical metal recoveries used for the formula are: 88% Zn, 70% Pb, 70% Cu, 33% Au and 82% Ag; these are based on historical recoveries at Woodlawn and supported by metallurgical testwork undertaken during the 2015-16 feasibility study. Commodity prices and metallurgical recoveries are factored into the zinc equivalent calculation using a standard metal equivalent formula.
