Geological survey works that led to the discovery of Teghout Copper-Molybdenum Deposit started in 1972. Exploration drillings and other geological works were carried out for around 20 years. As a result, the ore body geometry has been defined and the industrial reserves have been approved by the State Reserves Committee of Soviet Union.
Excavators carrying out the stripping works load the rocks into the trucks. During the pre-stripping phase all trucks transport the waste rocks to the waste dump. After reaching the ore body, the extracted ore is transported to the enrichment plant, while the waste rocks are transported to the waste dump. In the open pit is used machinery of the well-known Caterpillar Company. The excavators are CAT 6018 with 10 cubic meter bucket capacity. And the trucks used for transportation are CAT 777 F vehicles, with 90 tonnes carrying capacity.
Parallel to open pit also waste dump is formed.
During the recultivation works foreseen during and after exploitation the waste dump is covered with fertile soil layers, followed by plantation of trees and shrubbery.
Tailings from the enrichment plant are removed through a pipeline by gravity flow into the tailings storage facility in the River Kharatanots gorge. Natural water flows are removed from the gorge in advance, using the hydro-technical constructions.
The volume foreseen for the tailings’ allocation is formed through dam constructed by using clay and the waste rocks derived from the mine stripping. The filtered water collected as a result of squeezing the tailings is transported to the secondary sedimentation reservoir trough the collector.
With the raising level of dehydrated tailings, the wells receiving water on the lower level of the collector are closed, and the water is removed through the upper level wells. When the initial space is full, the dam is elevated by filling the sludge using upstream method.
After filtration in the secondary sedimentation pond, water is pumped back to the enrichment plant. The closed water cycle eliminates the possibility of polluting the environment by industrial effluents.
In parallel with the tailing dump exploitation, within the framework of recultivation works, the slopes of the dam and after the exploitation the whole surface of it are covered with a fertile soil layer and planted.
