Production has tripled since 2019 following significant investment to upgrade the plant and expand capacity, which was completed in 2024.
The Sekisovskoye Deposit is an exploration and development project of AltynGold.
It is located in the East of Kazakhstan, near the regional centre of Ust-Kamenogorsk. The underground work began in 2011 and is currently increasing with a target production of over 50,000 ounces in 2025.

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 Mining (later renamed AltynGold Plc) owned further exploration work.
The process and open-pit mining began in 2008. Today, the mining rights at the Sekisovskoye deposit belong to the 100% subsidiary DTOO GRP Baurgold, and the processing plant is owned by a 100% subsidiary of GMK Altyn MM LLP.

The Teren-Sai Project is an exploration and development project of AltynGold. It is located in the East of Kazakhstan and is adjacent to Altyn’s operating Sekisovskoye Mine. Estimated mineral resources are 9 million ounces of gold, as well as 16 million ounces of silver with the possibility of transferring ore reserves into industrial categories after further exploration.
The Subsoil Use Contract for the Teren- Sai Project is held by MMC Altyn MM LLP (“MMC Altyn”) a wholly owned subsidiary of Altyn. The Teren- Sai Project was granted Subsoil Use Contract No. 48-40-TPI, effective from 27 May 2016. The Subsoil Use Contract is an Exploration Contract, valid for gold ore, which covers an area of 221.25km2 but excludes an area of 0.56km2, resulting in a total area of 220.69km2. The excluded area forms the boundary for the Subsoil Use Contract for the Sekisovskoye Mine.
It has the potential to enable us to grow significantly beyond our core asset based at the Sekisovskoye mine with an area of 221 km2. While covering a total of 15 targets, Altyn’s initial focus has been solely on Area No.2 in particular two of its four breccia bodies.
The appraisal work carried out in this area, made use of the historic data purchased by the Company and related to core drilling, exploratory trenching and detailed metallurgical test work.
