Moscow, October 11, 2013 – Open Joint Stock Company “ALROSA” (ALROSA), reports production results for Q3 and 9M of 2013. During Q3 2013, ALROSA produced 9.9 million carats of diamonds, an increase of 9% compared to Q3 2012. ALROSA’s 9M 2013 diamond production reached 27.1 million carats, an increase of 6% compared to the same period of the previous year.

The increase in production was due primarily to the acquisition of the diamond mining company Nizhne-Lenskoye, an increase in ore grade at the Jubilee pipe and a higher output from the Mir underground mine.
