 Tunnelling of 4 000 m of the tunnel – first talc strike

On 10.4.2009 4000 m of the opening tunnel was punched in the newly opened talc deposit Gemerská Poloma and its completion on the entire length of 4200 meters is expected in the next month. This main opening work will serve as a transport and communication link of the surface with one of the most important deposits of talc in Europe.

The first position of the talc deposit has been stroked just in stationing 4000 m. False power of talcum position was more than 2 m and represented about 70% of mining works profile. Talc visually showed a high degree of whiteness and its other properties will be reviewed at laboratory tests. First tons of the raw materials got to the surface already in the tunneling of the opening tunnel, more will follow in the near future during the planned survey.

Immediately after completion of the opening tunnel tunnelling, detailed underground exploration of the bearing is continuously projected as a combination of drilling  and mining works in which will be the extracted materials used for technological tests as well as for commercial sales. The results of this survey will serve for further optimization of  the realization of the next mining works and mining process, which should in the future be up to 100 000 tons of the material annually.
