Woodlawn Zinc-Copper Project
Updated October 2017
Woodlawn is a high-grade, volcanogenic massive-sulphide (VMS) deposit situated in New South Wales, Australia, located approximately 50 km northeast of Canberra, and 250 km southwest of Sydney.
The Woodlawn Project benefits from a mining lease (SML 20) that has recently been renewed for a further 15 years, and major project approvals (statutory approval) that allows for mining operations at the Woodlawn site until 31 December 2034. The mineral rights and production are 100%-owned by Heron.
An attractive Feasibility Study was completed in mid-2016. The Feasibility Study for the “Starter Case” of the Woodlawn Project envisages an initial 9.3 year Reserves-based mine life with significant exploration upside in the underground mineralised system and regional prospects, and contemplates campaign treatment processing of 1.0-1.5Mtpa from two separate production sources - underground and tailings. The Project has an annual steady state production target of approximately 40kt (88Mlbs) zinc in concentrate, 10kt (20Mlbs) copper in concentrate and 12kt (25Mlbs) lead in concentrate, along with associated gold and silver.

A $240M funding package was subsequently approved by shareholders in August 2017 to fully fund the construction of the project and comprises debt, equity, and a silver stream. Construction and development work commenced on site in September 2017, led by Engineering, Procurement and Construction (EPC) contractor Sedgman under a Guaranteed-Maximum-Price (GMP) style contract.
First production is expected in late 2018 to early 2019.
Exploration within the project area is active and continuing, targeting additions to the mine’s resource base. A large number of available targets provides for both extensions to known massive sulphide positions and potential discovery of new lenses. Read more »
Heron also holds a portfolio of tenements adjacent to the Woodlawn site covering the prospective felsic volcanics that host the Woodlawn VMS deposit. The Woodlawn site (SML 20) is surrounded by a larger exploration license (EL 7257) which is held 100% by Heron. This exploration license, of 179 km², includes the previous Currawang Mine located 9 km to the north of Woodlawn. The Currawang Mine provided satellite feed to the previous Woodlawn operations.
