Learn about extracting and processing gold
At the Deepdell Viewing area, experience the complicated practice of extracting gold from the rock beneath our feet. Enjoy the 360-degree view into our active mine site including views of our Processing Plant, main open pit haul road and rehabilitated areas of our site.
Further along from this viewing area is the historic stamper battery Callery’s Battery, a DOC-protected historic reserve. Find out more here.
Underground Mining
We use tunnels to reach gold deep underground. The process of mining gold-bearing rock follows a cycle of drilling, blasting, bogging, ground support, hauling and rehabilitation.

Processing
The Processing Plant is responsible for removing gold from the mined rock. The six-stage process involves crushing and grinding, flotation and oxidisation, and leaching and adsorption.

Environment
Environmental work is an essential part of our operation and the mining cycle. We understand that mining is only a temporary use of land and that our communities have expectations on how our active mine is managed and rehabilitated, and the future land use once mining has ceased.

Lizard Rock Stacks
Rock stacks, or Lizard Hotels, are built to provide permanent refuge sites for the native McCann’s Skink, Southern Grass Skink, and Korero Gecko.
The design ensures the stacks are warm and dry, have small openings that deter predators from entering, and have suitable shrubbery planted around as a lizard food source.
With help from Ryder Environmental’s Steve Rate and Mandy Tocher, as well as University of Otago Researcher Cathy Rufaut’s development of ‘Lizard Hotels’, we’re able to rehabilitate and enhance our natural biodiversity.
Replicating the features of the natural rock outcrop around the Macraes area allows us to encourage the growth of the local lizard population and continue to provide research opportunities to understand these special native species.
