ALROSA (or “the Company”), the world’s largest diamond producer, announces its JORC compliant reserves and resources as of 1 July 2013 and an update on its Long Term Development Plan, including its capital investment programme.

The information presented below is an extract from an independent expert report (the “Micon Report”) that was prepared by Micon International Co Ltd. (“Micon”) assessing the JORC compliant reserves and resources of the major deposits of the Company. The assessment covered all major deposits of the Company, excluding certain alluvial deposits and undeveloped resources. The production plans and capital investment programme presented herein are based on the JORC production schedules for the deposits included within the perimeter of the assessment and on the Company’s Long Term Development Plan for the other assets.

As at 1 July 2013, ALROSA’s JORC compliant reserves were measured at 608 mct with an average grade of 1.34 ct/t, the Company’s compliant resource base stood at 973 mct (68% measured and indicated) with an average grade of 1.38 ct/t.

The following table summarizes the Reserves and Resources of ALROSA’s assets covered within the JORC audit perimeter as at 1 July 2013:

The Micon Report includes highlights from the Company’s Long Term Development Plan. In its Long Term Development Plan, ALROSA is targeting production of 36.4 million carats in 2013 and 41.3 million carats by 2021. In aggregate, the Long Term Development Plan assumes production of 353.2 million carats between 2013 and 2023. The estimated capital expenditures set forth in the Micon report amount to 33 billion roubles in 2013 and to 256 billion roubles in total during the period 2013 to 2021.

Cautionary Note: The targets set forth in ALROSA’s Long Term Development Plan are based on a wide range of assumptions about matters that are inherently uncertain, and ALROSA’s ability to execute its Long Term Development Plan is dependent on a wide range of factors, many of which are beyond its control. Many of the deposits for which the Long Term Development Plan targets future production are in a very early stage of development and in some cases further work remains to be done to verify the resources and reserves associated with the deposits. No assurance can be given that actual production will match the targets set forth in the Long Term Development Plan.
