About 300 people gathered in the Karangahake Gorge to protest against the New Talisman Gold Mines on Sunday.
A Coromandel Watchdog statement said the protesters' message was very clear; there was to be no more mining in Karangahake.
Neighbour to the mine, Mark Beach expressed his anger at not being properly consulted by the company and said he was yet to meet a local who had been consulted.
"When I saw the Hauraki District Council had issued them a resource consent I was angry and went to the Council to express my opposition. I was told all I could do now was take it to the High Court which seems like an impossible task for someone like me."
