All the signs told that the mine was a successful business and the fact was even mentioned in a newspaper from Kalamata, dated 02/04/1917: "We are happily informed that mining has begun in the mine of Prastova Lefktrou, and coal is already being transported to Piraeus. We are also informed that orders have been placed and received. " That was soon overturned, however, as mining stopped in the beginning of 1918. Due to large amounts of groundwater, the coal's quality was not good, thus it did not compete in the market and the company was dissolved. Zorbas remained in Kalogria for a few more months after the company's dissolution.
