Queenstown firm Steve Rout Contracting Ltd is safe from appeals to the Environment Court against its retrospective consent to mine schist at Earnscleugh, near Alexandra.
A timeframe within which people could appeal the Central Otago District Council's decision to grant consent closed this week.
Environment Court staff at Christchurch had not received any appeals when contacted.
Steve Rout Contracting was granted retrospective consent in December last year to quarry schist at Earnscleugh, near Alexandra.
The Central Otago Environmental Society made a submission opposing the company's application for consent, stating it would set a negative precedent for the district if granted.
An estimated 3000cu m of schist was extracted from 1ha of private property near Fraser Dam.
