In its effort to broaden its know-how, the company has attempted, on a trial basis and for the first time in lignite mining in Greece, to use open pit and underground mining operations simultaneously.The successful outcome of the above attempt will ensure:


(i) Extraction of the largest possible amount of the lignite deposit at the lignite mine of Prosilio and in any other lignite mines that satisfy the requirements. This allows for exploiting lignite deposits which, due to the high cost of extraction, were unsuitable for extraction so far.

(ii) Minimisation of the environmental impact of lignite mining.
