The National Tarkine Coalition has lost its legal action to stop a mine on the West Coast.
The group appealed against a decision made in August last year by then federal environment minister Mark Butler to approve a mine in Riley Creek operated by Venture Minerals.
Barrister for the National Tarkine Coalition Emrys Nekvapil had appealed the decision on four grounds, including the ``cumulative impact'' of other industry in the area and the impact on threatened species.
Justice Robert Tracey said Tarkine National had ``failed to make good any of its grounds''.
``Its application must, therefore, be dismissed with costs,'' Justice Tracey said.
Venture Minerals has previously said the proceedings were costing the company $50,000 a week.
