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, railballast, gabion material, blended road pavement products, manufactured sand, select fill, and drainage materials commenced in 2005.

The Austen Quarry Extension Project was approved in July 2015 and comprises the extension to the east and southeast and extension of the overburden emplacement area to the south. A modification to this consent (Modification 1) was approved in August 2018 to increase the rate of production and product despatch, extend operating hours, realign site boundaries and to amend the wording of conditions relating to offsetting obligations.

The operation provides access to proven reserves of 44Mt of rhyolite. This will be extracted and processed using convention drill and blast, load and haul methods with processing on-site in a dedicated processing area. Extraction operations at the Austen Quarry are connected to the processing plant by an innovative overland conveyor that provides power generating capacity through gravitational force. The current approval for the Quarry operation limits extraction to 1.6Mt per annum and sets limits on product despatch levels to ensure that operations minimise potential conflicts on the road network. Operations are currently approved to 30 June 2050.

The Austen Quarry is strategically located close to major roads and will be a future source of hardrock aggregates to meet the growing demand for these and other materials from the construction industry in the greater Sydney metropolitan region, as well as the needs of local and regional road works and other infrastructure projects.
