The Martha and Favona mines in Waihi, New Zealand, are operating gold and silver mines, managed by Newmont Waihi Gold.

The Martha Mine’s open pit is unique in New Zealand in that it is situated in a residential area, in close proximity to a thriving community; it is the subject of intense public interest. We are dedicated to maintaining operations in a socially and environmentally responsible manner. Restraints and conditions have been placed on the operation that take into account the mine’s proximity to the town. These conditions include hours of work, permitted blasting times and permitted noise, dust and vibration levels. The Martha Mine has been operating since 1988.

Following an extensive permitting process over several years, work began at the end of 2004 to construct the Favona underground decline. The Favona Mine began producing ore from stopes in 2006. Like the Martha Mine, Favona consent conditions are stringent due to the operation’s proximity to neighbouring residential properties.

Martha and Favona ore is treated at the processing plant, situated almost two kilometres from the open pit, beyond the town boundary and in a rural area,adjacent to the underground mine.  Water treatment and tailings storage facilities are also situated near the processing plant.

Consents to mine Trio were granted late 2010 and early 2011 and construction work has begun. Trio is an underground operation, accessed from the Favona decline and sharing the same portal (tunnel entrance) as Favona.
