Bathurst Resources says another appeal has been lodged against resource consents for its Escarpment mine in the Buller district on the West Coast.
The coal mine project was approved by independent comissioners in August.
West Coast Environment Network has lodged an appeal. Bathurst Resources says it now understands that the Fairdown Residents Association has lodged another.
The company says it will provide more information to the stock market when the appeal period ends, about 16 September.
The Royal Forest and Bird Protection Society of New Zealand says it will also appeal against the consent.
The society says open-cast mining would ruin the eco-system and it wants to protect what is left on the Denniston plateau.
The proposed open-cast mine is on a 200-hectare mining permit in the southern part of the Denniston Plateau. It is expected to produce about 1 million tonnes of premium hard coking coal a year.
It would be the second-largest open-cast coal mine in New Zealand, after Solid Energy's mine at Stockton.
