Meghradzor Gold Mine Belonging to "Meghradzor Gold" LLC To Be Developed for Another 17 Years

“Meghradzor Gold” LLC has submitted an amended application for the Preliminary Environmental Impact Assessment (EIA) of Meghradzor gold mine in Kotayq Region to Ministry of Environment. The company intends to extend the mining license by 17.2 years, which expires in September 2023.

Under the project, the annual productivity of the underground mine will be 60,000 tons per ore. The company intends to extract all the industrial ore reserves by underground mining within its planned 17.2 years. Under the project, the Marmarik River and its Gomur tributary, where the mine waters flow, are under the direct influence of Meghradzor mine. The Marmarik River is regularly polluted by water leaking from the tails of Meghradzor Gold Mine Processing Plant. The next alarm was beaten in May 2021.

The Marmarik river has the highest pollution, 5th class, the pollutant is manganese. According to the year-end data for 2020 presented by "Hydrometereological Monitoring Center" SNCO of RA Environment Ministry, the river in the Marmarik estuary was polluted with vanadium, iron, barium and potassium. The project says that the results of the monitoring carried out by the Institute of Mining and Metallurgy CJSC in the river sections 500 m below the mine in 2020 showed that the concentration of arsenic and that of determined metals in the waters of the Marmarik River corresponds to the quality of water grades 1-2, whereas the concentration of sulfates, chlorides and mineralization corresponds to the grade 3 of water quality.

Depending on the concentration of the materials, the Marmarik River has the 5th grade of water quality. After mechanical cleaning, the water of the mine transport ways flows into the Gomur River. Depending on the concentration of the material, the river is again of class 5 quality. Water quality according to zinc is in Classes 1-2.

Harmful emissions also occur as a result of mine operation. In particular, about 5 tons of harmful substances are emitted into the atmosphere annually, out of which 1.33 tons during explosion and 3,246 tons during operation.

 The environment is adversely affected by the wastes belonging to the mine and hazardous classes 3 and 4. In general, the volume of waste generated is about 35 tons per year.
