About Waihi North Project (Waihi District)
The Waihi North Project, which includes the high-grade Wharekirauponga Underground (WUG) is located approximately 10km north of the Waihi Operation. WUG is designed as a modern underground mine with minimal surface footprint that leverages the Waihi Operation’s current infrastructure. High-grade ore from WUG is to be delivered underground to the existing Waihi processing plant, which will undergo select upgrades to increase mill capacity.
