About Udokan

About Udokan


Udokan Copper (earlier known as Baikal Mining Company) was established in 2008 to develop the Udokan Copper Deposit in Kalar District of the Trans-Baikal Region (Russia).

With more than 26 million tonnes of mineral resources, Udokan is Russia’s largest and one of the world’s largest undeveloped copper deposits. The project includes a mine and processing plant that will produce copper cathodes and sulfide concentrate. The first stage of the plant will deliver up to 135 thousand tonnes of copper per year.

Committed to care for the environment and responsible use of natural resources, we implement the best available technologies to minimize our environmental footprint. Udokan Copper will process ores using our own patented flotation and hydrometallurgical technological scheme.

Udokan is a pioneer greenfield project in the industry. Starting from the construction phase, we follow global best practices in ESG, work on reducing our carbon footprint, develop regional infrastructure, protect the environment and support local indigenous peoples' traditions.

Udokan Cooper Deposit

Mining and Metallurgical Plant

Udokan Mining and Metallurgical Plant will produce copper cathodes and sulfide concentrate.

The first stage of the plant will deliver up to 135 thousand tonnes of copper per year. Udokan ores will be processed using a unique flotation and hydrometallurgy scheme.

We are now Udokan Copper

Udokan Copper completes constructing the railroad warehouse with rail loading terminals. The railroad warehouse will process cargo from the plant and will provide sufficient capacity for Stage 2 of the project as well.


Udokan Copper completed a major infrastructure project, connecting railroad warehouse with the Udokan Mining and Metallurgical Plant.

The new 17-kilometer road is 6 meters wide to support the transportation of 700 thousand tonnes of cargo per year.

It will be the key logistics asset supporting deliveries to Udokan MMP as well as transportation of its products to the key regional transportation artery, Baikal-Amur Mainline.


The airport at the settlement of Chara is a gateway to the north of the Trans-Baikal Region.

Udokan Copper created an airport redesign project that includes the construction of a new 80 passenger-per-hour terminal with a medical office, maternity room and a food court. Runway and taxiways will be reconstructed and the territory - landscaped. Airfield will be lit to support 24x7 operation.

Project documentation was submitted to the Trans-Baikal Region authorities, and the reconstruction started in 2022.


A sufficient amount of electric power is required to build and operate the MMP. The existing 220 kV Chara substation fully covers project construction needs.

A new overhead power line “Tynda – Lopcha – Khani – Chara” as well as a section of overhead power line from Chara substations to MMP site were built in 2022 in order to meet the needs in power supply for the plant.

Corresponding Member of the Academy of Sciences of the USSR Yuri Bilibin demonstrated the rationale for exploration in the area from the source of the Vitim river to the middle course of the Olyokma river, suggesting the similarity of the geological structure of this area with Central African Copperbelt.


Lead Geologist of Sosnov Expedition Elizaveta Burova discovered the unique Udokan copper deposit on a trail along an unnamed stream, a left tributary to the Naminga river.


Udokan Exploration Team was established in 1952. Reconnaissance of the Udokan copper deposit was completed in 1953—1958. In 1960, a government resolution on the accelerated exploration of the Udokan deposit was issued with the objective to complete the first stage of exploration by 1964. When the exploration was completed, further work at the Udokan deposit was suspended in 1965 and shut down in 1966. The photograph shows the members of Udokan Exploration Team.


The new life of Udokan deposit started with the beginning of construction of Baikal-Amur Mainline in 1975. Over the next five years, detailed exploration was conducted within the pit contour (70% of the overall copper ore reserves), bulk samples were tested, and ore reserves were recalculated. Mine and processing facility with a copper-chemical plant have been slated for construction since 1970s. Udokan MMP project designs were prepared in 1969, 1972, 1980, 1995 and 2000. Moscow State Expertise classified these projects as not feasible. The photo shows Zapadny section of the deposit, 1976.


Mikhailovsky Mining and Processing Plant won the mining license for Udokan deposit in an open tender. Baikal Mining Company (BGK) was established to develop the deposit. Since 2008, Baikal Mining Company, today known as Udokan Copper, has been holding the mining permit for copper and associated components based on license CIT 14956 TE issued by the Russian Federal Agency for Mineral Resources.

Metal of the Future

Copper is an indispensable metal that fueled revolutionary progress in the history of the humankind. Copper Age, the period of early metalworking in Eurasia, gave birth to metallurgy.

Due to its high electrical and thermal conductivity, corrosion resistance and strength, copper is in high demand, especially in high-tech industries. Today, scientists call the modern stage of the industry development the New Copper Age.

Uses of Copper

Copper has always been and remains the driver of revolutionary changes in telecommunications, from phones to high-speed computer links, satellite technologies and wireless communications.
Engineering Infrastructure
Copper is indispensable in construction; it is the most important metal used in production of wires, water and heating pipes and construction materials. Copper has the highest electrical and thermal conductivity out of all metals, and it is widely used in the energy industry.
Low-Carbon and Green Technologies
Copper is more important for the renewable energy than it is for traditional power plants. Copper usage intensity in renewable energy is four to six times higher than in nuclear and coal power stations. Wind and solar photovoltaic energy systems use the most copper among all renewable energy technologies.
Electric Vehicles
Passenger electric vehicle manufacturers will require more than 3.7 million tonnes of copper per year by 2040.
Copper in Healthcare
Copper is an important biological element necessary for normal development of plants and animals. It accelerates chemical processes within cells. Copper is also a natural antibacterial agent. In 2008, antimicrobial properties of copper surfaces were officially recognized by the United States, and in 2009, the effectiveness of copper and its alloys was proven at inactivating the A/H1N1 influenza virus.
