Mt Cotton Quarry’s active quarry area is being extended to help meet the growing demand for construction materials in our region. The hard rock resources in our previous extraction zone were depleted.
Barro Group received development approval for the extension project, with conditions, in 2013. Following several approved changes to the development timeframe, works to enable the quarry extension began in 2023.
The total approved quarry extension is 45 hectares, which will be conducted in stages over several decades.
Stage 1 of the extension will establish an active extraction zone of about 15 hectares. A new intersection with Mt Cotton Road and internal access road will be constructed, quarry dams and drainage upgraded, modern crushing and screening equipment installed, and site buildings upgraded.
To reduce any potential visual or noise impacts for surrounding residents, a new 8m high vegetated bund has been built around the new quarry zone.
More than 190 hectares (approximately 75%) of the 250 hectare site will be retained for conservation purposes.
Features of the extension project are shown on the map.
