Mine planning

Nearly 1 km below the surface. That’s how far the boreholes reach in the Viscaria Mine. And that’s just the beginning.


The deposit

Viscaria’s mining deposit is divided into three zones and extends 4 kilometers horizontally. Vertically, the ore bodies are mapped down to 800 meters deep. Many of the mine tunnels preserved from previous underground mining will be able to be repaired and reused if the mine is reopened. Additionally, the mine’s infrastructure will be expanded to reach all parts of the deposit. Under Viscaria’s management, mining is planned to occur both in open pits and underground.

Viscaria is what’s known as an open deposit, meaning its outer limits in vertical and horizontal directions have not yet been mapped. Therefore, exploration and surveys continue in parallel with the work to reopen the mining operation.

Viscaria aims to be a mine with minimal environmental and climate impact

Through water purification, efficient resource utilization, and modern infrastructure and mining technology, the impact from mining operations at Viscaria will be minimal.
