Republic of Karelia, for construction stone production purposes in accordance with Western standards. Using geological research and trial mining, a high-quality quarry site would be identified. In order to study the quality of the stone, the intention was to bring sample batches to Finland for research. Some of the samples would also be studied in Russia. Modern mining equipment was to be utilised and a research boring unit was to be developed to serve the mining needs. The project was to train the personnel for the mining of the stone type in question. In addition, the international marketing opportunities for Ruskeala marble and the possibility of establishing refining operations at Tohmajärvi were to be researched.
