PROCESSING PLANT UPGRADE​

We are pleased to share that an Expert Panel has made a final decision to grant approvals for the Waihi North Project.

​
This project displays OceanaGold’s ability to continue to support economic growth, create high-paying jobs, generate royalties, support communities, and boost exports at the same time as making a positive contribution to the environment.  

OceanaGold will now commence the next phase of the Waihi North Project. Several conditions are attached to the project, most of which align with our current operating practices. Our immediate priority is finalising Management Plans that outline how we will meet these conditions.  At the same time, we will continue work on the services trench to allow water to be moved between the Willows Road site and our existing Water Treatment Plant which will be upgraded. Construction will also begin on a surface infrastructure area on the farm on Willows Road to support the future commencement of tunnelling works.   

The final decision and related conditions and technical documents can be viewed here: Fast-track ​

PROCESSING PLANT UPGRADE​

Our existing Processing Plant has been in operation at Waihi since 1987. The Waihi North Project requires a plant upgrade to increase its capacity and extend its life for a further 14 years.

The proposed upgrade would increase processing capacity from its current annualised rate of 1.25 million tonnes, up to 1.6 million tonnes. 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 Company’s Reefton Mine, where mining has now concluded.
  • Refurbishment of the adsorption circuit and installation of new pumps and pipelines to transport tailings to TSF3.
As part of these works, we will also upgrade our existing Water Treatment Plant, and temporary project facilities, such as offices, parking, and equipment laydown yards will be required during the upgrades. These facilities will be built within the current footprint of the Process Plant and will be removed once the upgrade work is complete.
A benefit of these upgrade works is that they provide additional jobs during the construction phase.
Under this proposed project, both the Process Plant
and Water Treatment Plant would continue to operate 24-hours-a-day, seven days a week.
