Discovered in 1964, the Mazimchay copper deposit is located in Balakan region, 2-3 km away from the Filizchay deposit. In 2020-2022, comprehensive exploration works were carried out here to estimate the reserves of the deposit and its efficiency. Depending on the metallurgical test results, the Mazimchay deposit will be exploited together with the Filizchay deposit, since it is not considered economically efficient if processed separately.
