Name and Location
Woodlawn zinc/copper project, New South Wales, Australia.

Client
Heron Resources.

Project Description
The preliminary economic assessment (PEA) on the Woodlawn project has confirmed the economic viability of the project. The PEA envisages a combined underground and tailings retreatment project, with feed processed through a single plant designed for co-treatment.

The mine will have an initial mine life of 11 years based on underground and tailings resources, including underground resources comprising indicated mineral resources of one-million tonnes and inferred mineral resources of 2.8-million tonnes.

Total life-of-mine production is estimated at 353 000 t of zinc, 77 000 t of copper, 112 000 t of lead, 8.9-million ounces of silver and 59 000 oz of gold.

The operation will have a processing rate of 1.5-million tonnes using standard sequential flotation, with a steady-state production rate of 51 000 t of zinc, 10 000 t of copper, 16 000 t of lead, 1,1-million ounces of silver and 8 700 oz of gold contained within zinc, lead and copper concentrates. Significant reductions in development costs will be achieved using existing infrastructure.

Net Present Value/Internal Rate of Return
The PEA indicates a post-tax net present value, at an 8.3% discount, of $300-million and an internal rate of return of 46%, with an initial payback two years from the date of commissioning.

Value
Initial capital expenditure is estimated at A$140-million.
