Austen Quarry - Project Profile

Client: Hy-Tec Industries Pty Limited
Industry: Quarrying
Status: Approved and Operating
Local Government Area: Lithgow City


The Austen Quarry is located approximately 3.5km south-southwest of the village of Hartley and 10km south of Lithgow. Development consent was originally granted to Aus10 Rhyolite Pty Limited in 1994, however, production did not commence until Hy-Tec Industries Pty Limited (Hy-Tec) entered into a lease to become the operator of the quarry in early 2002.  The production and sale of a wide range of aggregates, rail ballast, gabion material, blended road pavement products, manufactured sand, select fill, and drainage materials commenced in 2005.

The Austen Quarry Stage 1A Extension Project, currently before Lithgow City Council for determination, provides for an increase in the depth of extraction (of 30m) within the existing extraction area.  Approval of the Stage 1A Extension will ensure that a ridgeline within the approved extraction area, which has been retained to reduce the visual impact of the quarry from vantage points to the north, may be retained whilst assessment and determination of the larger Stage 2 Extension is completed by the Department of Planning & Environment.

The Austen Quarry Stage 2 Extension Project comprises the extension of the existing extraction area to the east and southeast and extension of the overburden emplacement area to the south. The extension will provide access to proven reserves of 44Mt of rhyolite. This will be extracted and processed using similar methods and processes as current operations with product despatch not exceeding the existing maximum rate of 1.1Mt per annum. Should the extension be approved operations at the quarry will continue for an additional 30 years.

The extension to the extraction and overburden emplacement area and the corresponding lengthening of the operational life of the Austen Quarry will allow Hy-Tec to meet the growing demand for aggregates and other materials from the construction industry in the greater Sydney metropolitan region and the needs of local and regional road works and other infrastructure projects.
