Kučín Quarry

Clinoptilolite is the extractable raw material in the deposit and is evenly distributed throughout the rock on-site. The Kučín deposit has confirmation of the high quality of the natural clinoptilolite, which is among the highest quality deposits in the world.

The deposit and the mining area are located 300 m to the south-west of the town of Kučín in the Vranov nad Topľou district. From a geological perspective, the deposit band of zeolite tuff between Kučín and Pusté Čemerné forms a single contiguous unit.  The deposit was created by zeolitization of ash ryodacite tuffs settled in an aquatic (marine) environment. The deposit is in a single layer. The massive complex of Hrabov tuffs is the result of a single volcanic and sedimentation process that was not interrupted by another sedimentation process.

The 0.24 km² deposit is located approximately in the north-western part of the zeolite tuff (Hrabov tuff) deposit zone of the Lower Hrabov Layer (late Badenian Eastern Slovak Neogene Basin). The body of the deposit forms an irregular polygon on the surface (in the area of the plate body).  On the surface, the longest lengths are 1240 m from north-west to south-east and 184 m from north-east to south-west and covers 23.54 hectares.

A total of 23,820,000 are the calculated and approved zeolite reserves in the designated Kučín deposit.
