Karelian Diamond Resources plc expects an August court judgement over compensation and the boundary of its diamond mine development at Lahtojoki in Kuopio Kaavi, Finland.
Two farmers previously appealed against money owed to them as well as the site boundary.
Karelian said that following the court hearing on 21 May, the Finnish Land Court announced it would give its ruling 12 August.
The Lahtojoki diamond deposit contains “high quality colourless gem diamonds, pink diamonds and other coloured diamonds”.
The company is also exploring for the source of green diamond also discovered in Finland.
