TSX- and NYSE-listed Turquoise Hill Resources has flagged potential further delays in the development schedule of the Oyu Tolgoi underground mine project, saying that the completion of ‘technically complex’ installations at Shaft 2 could take longer than previously thought.
The Rio Tinto-owned company, which holds the giant mine in a 66:34 partnership with the Mongolia government, last year said that sustainable production of $5.3-billion underground mining project would only be achieved in the third quarter of 2021 rather than the previously guided start of 2021.
