Angas Zinc Mine
CLIENT: Teramin Australia Limited
LOCATION: Strathalbyn
WORKS COMPLETED:
The Angas Zinc Mine site, located near Strathalbyn on South Australia’s Fleurieu Peninsula, was historically operated as a quarry and retained only sparse natural vegetation. Decades of disturbance left the land heavily degraded, with minimal habitat value for native fauna. As a condition of securing its mining lease, Terramin was required to demonstrate that operations would not result in a permanent loss of biodiversity from native vegetation clearance. Legacy impacts from quarrying were clearly visible: dust emissions, exposed mine infrastructure, and extensive stockpiles of soil, ore, and waste rock. These factors created significant erosion risks, diminished the site’s visual amenity for the surrounding community, and posed ongoing environmental challenges. The most critical issue was the 45-degree boxcut slope above the mine entrance. Comprised of highly erodible clays, it was prioritised for immediate stabilisation to prevent further land degradation and off-site impacts.
