GCR Mongolia, a joint venture between Gobi Infrastructure Partners and RUC Mining, says it has reached a depth of 1,000 m on Shaft #4 at the Oyu Tolgoi mine in Mongolia.

On the achievement, RUC Mining said: ­“This achievement is a testament to the unwavering dedication and efforts of our exceptional shaft sinking project team.”

Back in 2018, GCR Mongolia was awarded a contract to design, construct and commission the sinking and lining of Shaft #3 and #4 and build the stage one material handling system at the copper-gold underground project.

The shaft sinking aspect for these ventilation shafts involves blind sinking and concrete lining of the two shafts, while the material handling system will require the installation of 9 km of conveyors able to transport ore to surface at 6,500 t/h. Shaft #4 was planned to be sunk to a depth of 1,200 m with a finished diameter of 11 m.

Oyu Tolgoi, in the southern Gobi Desert of Mongolia, is expected to produce the equivalent of 500,000 t/y of copper at its peak.

The GCR Mongolia joint venture has won more work at Oyu Tolgoi, with the three partners set to design, construct and commission the sinking and lining of Shaft #3 and #4 and build the stage one material handling system at the copper-gold underground project.

GCR was previously awarded a contract by Jacobs Engineering to carry out bulk and detailed earthworks, civil and concrete works for major concrete structures and buried services, plus decommission 35 kV overhead powerlines at Oyu Tolgoi.

The shaft sinking aspect of the new contract involves blind sinking and concrete lining of the two shafts, while the material handling system will require the installation of 9 km of conveyors able to transport ore to surface at 6,500 tonnes per hour.

Oyu Tolgoi, in the southern Gobi Desert of Mongolia, is expected to produce 622,000 tonnes of copper and 669,000 ounces of gold at its peak in 2025. It is jointly owned by the government of Mongolia (34 %) and Turquoise Hill Resources (66 %), with Rio Tinto the majority owner of the latter.

GCR Mongolia is a registered Mongolian company that combines the expertise and experience of Gobi Infrastructure Partners, Clough Projects International and RUC Cementation Mining. It is focused on providing clients a complete solution to construction, infrastructure and mining development projects throughout the region.
