PROCESSING PLANT UPGRADE
Our existing grinding mill is over 50 years old and has been in operation at Waihi since 1987. the Waihi North Project requires the mill to operate for a further 14 years, and at an increased capacity. In order to meet this increased demand, the current mill would be upgraded.
The main components of the process plant upgrade are:
These works would increase ore processing throughput from its current capacity of 1.25 million tonnes a year, up to 2.25 million tonnes a year. A further benefit of these works is that they begin early in the project’s timeframe and provide additional jobs.
Under this proposed project, the Process Plant would continue to operate 24-hours-a-day, seven days a week.
As part of these works, we are currently investigating opportunities to upgrade our Water Treatment Plant.
The main components of the process plant upgrade are:
- Replacing the existing mobile and jaw crushers with a modular primary crusher.
- Increasing current milling capacity by installing the mill from the Reefton mine.
