Prairie Mining Limited shares surged 18.5% to 32p in late-afternoon trading after it confirmed ongoing partnership talks with Polish firm Jastrzebska Spolka Weglowa SA (JSW).
The miner signed a non-disclosure agreement with JSW in March to allow for talks over a possible cooperation agreement for its coal projects in Poland.
Prairie own the Jan Karski project in the east of Poland as well as the Debiensko hard coking project in the south-west.
The company said talks were continuing at present but cautioned that they were still at an early stage.
