The mine recommenced operation in 2019 with refurbishment of its crushing system, Merrill-Crowe plants and mining fleet. Initially the mine was restarted with the construction of test leach pads to demonstrate the sulfide oxidation and leach process on a commercial scale.
The Merrill Crowe gold recovery process removes precious metals from a cyanide solution by zinc precipitation. The pregnant solution is first clarified through filters such as horizontal leaf type clarifiers. By using a precoat system with diatomaceous earth an extremely clear solution can be produced.
