- Prairie Mining said it received mixed court and regulatory results in Poland, with an administrative court ruling over one concession going its way but a government decision for another potentially going against the company.

Prairie said Poland's Supreme Administrative Court had finally and fully rejected rival Lubelski Węgiel's administrative complaints against a refusal by authorities to grant it a mining application in 2013 for the Jan Karski concession.

In a related ruling for that same first case, the court upheld a 2016 decision that obliged authorities to approve Prairie 's detailed resource estimate for the concession.

However, for the separate Debiensko coal mine concession, the company said Poland's environment ministry may limit or withdraw the concession.

'Prairie will strongly defend its position and continue to take relevant actions to pursue its legal rights regarding the Debiensko concession, including filing an appeal,' the company said.

'Preliminary legal advice obtained by Prairie indicates that the ministry's decision is fundamentally flawed, fails to comply with Polish, EU and international law, and demonstrates yet further evidence of the discriminatory treatment faced by Prairie as a foreign investor in Poland.'
