Rio Tinto PLC Friday said the development of an underground operation at the Oyu Tolgoi copper mine in Mongolia's South Gobi region continues to be significantly constrained by Covid-19 related restrictions, and that costs linked to pandemic delays are mounting.
The world's No. 2 miner by market value now expects first sustainable production from the project no sooner than January 2023, versus an earlier projection of October 2022. In addition to pandemic-related setbacks, parts of the project are being held up because its owners haven't approved additional funds needed for the development, Rio Tinto said.
Oyu Tolgoi is 66% owned by Turquoise Hill Resources Ltd., in which Rio Tinto has a majority stake. The Mongolian government owns 34%.
Rio Tinto estimated the commissioning of shafts three and four at the site would be delayed by roughly nine months because of pandemic-related restrictions including difficulties getting experts to the mine. The impact on project costs of the additional restrictions related to Covid-19 to the end of September 2021 are estimated at $140 million, Rio Tinto said in a quarterly operational report.
Oyu Tolgoi is one of the largest known copper and gold deposits in the world. A Rio Tinto-led venture plans to build a vast network of underground tunnels at the site, where it has already built an open-cut mine, to turn it into one of the world's largest copper-mining operations.
However, the project has been repeatedly delayed, not just by Covid-19 but by negotiations with Mongolia's government over how to split the profits from the mine.
Mined copper production from the existing open pit at Oyu Tolgoi was up 16% in the third quarter of 2021 versus the same period a year ago, as the operation sought to recover from geotechnical issues in the first half of the year despite a thinned workforce due to Covid-19, Rio Tinto said in its operational report.
While the transport of copper concentrate to China from Mongolia has resumed, a force majeure declared on shipments from March 30 remains in place because of uncertainties in moving commodities across the Mongolia-China border, Rio Tinto said.
"We continue to work closely with the Mongolian and Chinese authorities and our customers to manage the risk of supply chain disruptions," it said.
