Rio Tinto Diamond's production down 8% for Q1

21 april 2017
In a statement recently, mining major Rio Tinto has released its production update for the quarter ended March 31, 2017, wherein it has reported that diamond production has recorded 8% year-on-year drop to 4.152 mn carats as compared to the 4.522 mn carats produced in the same quarter in 2016.
According to the company, its wholly owned Argyle mine in Australia produced 3.016 mn cts, which was 11% below the comparative figure for the same quarter in 2016. The fall was attributed to lower ore volumes processed as well as lower recovered grades.
At the Diavik mine in Canada, where the company owns 60%, the production amounted to 1.136 mn carats, which is almost the same as against 1.131 mn carats produced in 2016 that was recovered in the same quarter a year earlier. Rio Tinto said that the lower ore throughput at the mine was offset by higher recovered grades.
It also reported that the development of the A21 pipe remains on schedule.
Rio Tinto said that diamond production guidance for 2017 remains unchanged at 19 to 24 mn carats.
