The Garden Well Operations include Garden Well open pits, Tooheys Well, Russell’s Find and Erlistoun open pits. Underground operations at Garden Well South commenced in 2021.

The Garden Well and associated deposits are mined using conventional open pit mining truck and shovel methods. The plant design is based on a nominal 5Mtpa throughput rate utilising a two stage crushing circuit, scrubber and single ball mill. The carbon in leach circuit is larger in capacity to enable processing of the Rosemont feed in slurry at a combined rate of approximately 7.5Mtpa.
