Location and History


Taborny mine (Tabornoe gold deposit) is located in the southwestern Sakha (Yakutia) Republic in Russia some 125km northeast of the Ikabya station on the BAM railway. It is around 200 km from the town of Chara and is accessible via an all-season road (a 10 hour journey) or alternatively a one hour helicopter flight to site. The workforce is accommodated on site and power is generated by diesel generators.

Tabornoe ore is mined at a rate of 3Mtpa, ore grades at Tabornoe are typically between 1.0 and 1.3 g/t with gold recovery from heap leach and downstream adsorption and desorption circuits varying between 63% and 73%.

The area is mountainous the project is at an elevation of 1,100m to 1,300m above sea level. The climate is very cold much of the year, there is snow cover between October and May and a short hot summer. Rivers are frozen from November to April and permafrost extends to approximately 400m depth although up to 3m of soil may defrost in the summer.

Nordgold acquired the mine in 2007. The Mining licence for Tabornoe covers an area of 0.93km2 and has been held by Taborny since 2001; it is currently valid until the end of 2020.

The Taborny mine operates the Tabornoe gold deposit and is the location for Nordgold’s pilot stage Gross project.

Taborny has a processing plant with crushing and heap leach extraction capabilities. Operations at Taborny utilize the simplest heap leach extraction method available, due to the highly oxidized low-grade ore. Production at Taborny is subject to significant seasonal variations due to harsh winter temperatures. The majority of crushing and stockpiling of ore occurs from May to September, and the majority of gold production occurs from July to December, as the cyanide spray used in heap leaching cannot penetrate frozen ore.

Milling and Classification
Nordgold’s open pit operations use conventional surface mining methods involving drilling and blasting, followed by a load and haul process allowing for selective mining of the ore. Ore from the pit is then transported to a designated stockpile and fed into a crushing circuit. The sized ore is then conveyed to a Heap Leach Facility.
The ore is heaped on a clay lined leach pad where it is irrigated with the sodium cyanide leach solution. The solution percolates through the heap and leaches gold from the minerals. The leach solution containing the dissolved cyanide gold ("pregnant solution") is then collected, treated in a process plant to recover gold on carbon and then recycled to the heap after reagent levels are adjusted.
The final gold loaded carbon is removed and washed before undergoing elution. Elution is achieved by introducing the gold loaded carbon to a solution of caustic at a high temperature (>110°C) and under high pressure. This results in the reversal of the attachment process, with the gold detaching from the carbon back into solution. This produces a small volume of solution with a high gold concentration.
The gold loaded eluate solution that emerges from the elution process is passed through electrowinning cells, where gold is deposited onto the cells’ cathodes.
The cathodes then undergo a smelting process, further refining the gold and leading to the eventual production of gold ingots suitable for transport to a refinery.

2018 Deliveries

  • Additional mining fleet was acquired to ramp up mining volumes to 24Mt per annum with the objective to maximize the current Taborny heap leach processing capacity of 4.6Mtpa.
  • From Q1 2018, ore mining from Tabornoe and recently permitted Temnii and Trench 7 open pits are matching the Taborny heap leach processing capacity of 4.6Mtpa (displacing previously processed Gross ore are Taborny).
  • Development of the recently permitted Temnii and Trench 7 open pits, and cutbacks to the main Tabornoe pit is in progress in 2018.
  • Processing continues to increase HL irrigation volumes, and new pad construction commenced for future ore stacking.
  • Regional exploration is focused on the Tokkinsky area.
