Woodlawn History

The Woodlawn deposit was discovered in 1969 and operated from 1978 to 1998 under various owners. It was mined both as an open pit operation and from underground positions, and also ran a tailings retreatment operation for a number of years. The mine was closed in March 1998 due to prevailing low metal prices and external corporate issues with the then-owner, Denehurst Limited.

During the operations the mine processed:

  • 8.0Mt @ 8.3% Zn, 1.6% Cu, 3.1% Pb and 62g/t silver (Ag) from the Woodlawn open pit between 1978-1987;
  • 530,000t @ 13.0% Zn, 1.6% Cu 2.2% Pb and 33g/t Ag from the satellite Currawang mine between 1991-1995, and
  • 5.8Mt @ 10.1% Zn, 1.6% Cu, 4.1% Pb, 0.5g/t gold (Au) and 90 g/t Ag from the Woodlawn Underground between 1987-1998.

Post mine closure, the mineral rights contained within the Woodlawn Mining Licence SML20 were purchased by an entity which became TriAusMin Ltd. Since that time, work focused on evaluating the potential to re-process the medium grade tailings from previous mining operations, and to re-develop the underground mine.

Regional exploration has also been undertaken in the vicinity of Woodlawn with the objective of discovering new, high grade satellite deposits.
