Rio Tinto subsidiary Turquoise Hill Resources, which owned a 66% interest in the significant Oyu Tolgoi copper/gold mine, in Mongolia, on Tuesday said the mine’s first quarter performance was so strong, that it hiked its full-year production guidance.
For the three months ended March 31, Vancouver-headquartered Turquoise Hill advised that the Oyu Tolgoi operation’s concentrator throughput reached a quarterly high, as well as better-than-expected gold production.
