Newmont Waihi Gold has announced plans to build another underground mine.
The Correnso Mine in Waihi East would replace the existing Favona and Trio mines.
General Manager Glen Grindlay says the mining would occur at a depths of between 350 and 130 metres beneath some Waihi East properties, which could be a concern to some residents.
But he says the company will talk with those likely to be affected in the coming weeks to work through any issues.
Newmond Gold expects to apply for resource consent for the new mine by early next year, and have it operational by mid-2013 if it is approved.
