The Sekisovskoye deposit was discovered in 1833 and surface mining was carried out from 1833 to 1847, from 1932 to 1935, and from 1943 to 1946. From 1975 to 1986, a complex of exploration work was carried out. Between 1978 and 1982, the artel "Altai Gold" of the Ministry of Non-Ferrous Metallurgy of the KazSSR introduced mining in the area of an oxidized primary source.
In 2003, Hambledon Ming (later renamed Altyn Plc) owned further exploration work, and gold mining at the mine and the processing plant began in 2008. Today, the mining rights at the Sekisovskoye deposit are located in the 100% subsidiary DTOO GRP Baurgold, and the processing plant is owned by a 100% subsidiary of GMK Altyn MM LLP.
STATUS
The mine was in operation for 8 years and ore reserves for open-pit mining were completed at the end of 2016. Limited underground work began in 2011 and is currently increasing with a target production level (Stage 1) of 100,000 ounces per year.
