Mineral deposits and reserves of geothermal water belong among the important natural resources in the hinterland of the city. Deposits of granodiorite and ceramic clays are only of local significance.

Reserves of high-quality magnesite are of greater importance. The deposit was exploited by underground mining. Currently, the exploitation was temporary stopped. From the point of view of its size, temperatures and depth, the Mesozoic of Košická kotlina Basin belongs among the most prospective regions of Slovakia suitable for the use of geothermal energy. Temperature of water is ranging from 27 to 182°C. From the chemical point of view, this water is of the Na-Cl type with mineralisation ranging from 10.6 to 30.2 g.l^-1 (strongly to very strongly mineralised water). CO₂ prevails from among gases.

The prospective thermal and power potential of geothermal energy reserves, which is suitable for exploitation by the system or re-injection, represents 1,276 MW for the thermal gradient from 119°C to a reference temperature of 15°C.

Hot geothermal water can be one of the main sources of heat for the system of central heat supply for Košice and a few adjacent villages, as well as for other use in the power engineering industry.

At the same time, the basis for the development of greenhouse management, breeding of fish and recreational and sports activities of the city population is being established.

The ”Utilization of Geothermal Water of the Košická kotlina Basin” project is assessed now within the EIA process.
