The Pavlovskoye lead-zinc project is classified as one of the biggest mines in Russia. Located in the Arkhangelsk region, the project is expected to contain reserves sufficient for up to 35 years of production.

ARMZ Uranium Holding subsidiary First Ore Mining Company is developing the project, which is estimated to have an output capacity of up to 3.5Mt of ore a year.

The project was included in the ‘Social and Economic Development of the Arctic Area of the Russian Federation’ programme.

ROSATOM and the Arkhangelsk government signed an agreement to co-operate for the implementation of the Pavlovskoye project as part of an overall development of the Arctic Zone of the Russian Federation, in March 2017.

The Pavlovskoye lead and zinc deposit was granted priority investment project status by the Governor of Arkhangelsk Region in March 2018. Construction of the combined mining and processing unit is proposed to start in 2018, and with first commercial production expected to start in 2020.

Pavlovskoye lead-zinc project location, geology and mineralisation

JSC The First Ore Mining Company discovered the deposit in 2001 and undertook prospecting and appraisal between 2001 and 2002, which identified approximately 37Mt of С1 and С2 category lead-zinc-silver ore reserves.

“The project was included in the ‘Social and Economic Development of the Arctic Area of the Russian Federation’ programme.”

Spread over 12km², the Pavlovskoye ore field is one of the biggest polymetallic ore facilities of Bezimyanskoye ore cluster. It adjoins the offshore part of the Barents Sea and is located at the distance of 16km-18km from the deepwater, bay capable of receiving sea vessels with the displacement between 6,000t and 8,000t.

The project hosts terrigenous, terrigenous-clayey, and carbonate rocks belonging to the Silurian-Devonian age. The rocks are shallowly submerged towards the south and south-eastern direction.

The project hosts two productive deposits of lead and zinc ores namely Eastern and Central, which have a band-like morphology with a thickness ranging from 10m to 120m. The mineralisation was evaluated by trenches and boreholes along a strike length of 800m-900m, dipping downwards by more than 400m.

Pavlovskoye lead-zinc project reserves

The Pavlovskoye project is estimated to hold approximately 47.7Mt of ore containing 2.49Mt of zinc, 0.55Mt of lead and 1.2Mt of silver.

Mining and processing of ore at Pavlovskoye

Conventional open-pit mining method is proposed to be used at the Pavlovskoye lead-zinc project, which comprises three open pits.

An estimated 2.5Mt of ore a year is proposed to be recovered from the mine and delivered to the enrichment plant. The proposed processing plant will feature a process flotation system to produce lead and zinc concentrates, which will be dried and shipped to consumers.

The ore processing complex will consist of a 500,000 tonnes per annum (tpa) mill, which is expected to produce approximately 220,000t of zinc concentrate and 50,000t of zinc concentrate a year. Final concentrates will be shipped to customers from the Bezymyannaya bay port, to be constructed by Rosatom.

The produced lead concentrate is proposed to be supplied to plants located in Russia, Europe and the People’s Republic of China, while the zinc concentrate will be sent to the Russian processing facilities and Sweden-based metals company Boliden.

Pavlovskoye project construction

First Ore Mining completed the first stage of the field season of the Pavlovskoye deposit in November 2016 and conducted field operations related to engineering surveys for the construction of the mine and the processing complex in 2017.

The company also conducted engineering surveys for the onshore facilities, collected semi-industrial samples, and developed the operating procedure for enrichment of lead-zinc ore.

A port complex on Novaya Zemlya is proposed as part of the Pavlovskoye field development. Engineering surveys for the design of the main underwater part of the port complex were carried out in July 2018.

Infrastructure facilities

 Major infrastructure facilities of the project will include a 450-person shift camp and an administrative and utility building complex.

The port dock-side facilities are expected to include an open trans-shipment warehouse and facilities for fuel, lubricants and liquefied natural gas.

Contractors involved

JSC Rusburmash, an exploration company of ROSATOM’s mining division, was awarded the contract for conducting exploration at the Pavlovskoye field.

JSC VNIPIPromtechnologii was engaged as the general design engineer of the project and was also awarded the contract for the port development at Novaya Zemlya.

Shaneco Design Institute participated in preparing the pre-feasibility study report of the Pavlovskoye deposit.
