Reserves/Resources and Brief Description of Geology
The volume of ore reserves is 104 million tons of lead-zinc ore (3.4 million tons of zinc metal in ore, 0.9 million tons of lead metal in ore).
2016 – development of a project for the industrial development of the mine; elaboration of technological regulations; development of a Bank Feasibility Study (BFS).
June 12, 2017 – Loan Agreement with the EBRD – initially, the Project implementation strategy provided for a turnkey EPC scheme, which was the basic decision of the BFS and, accordingly, was accepted by the EBRD loan agreement.
