The diamond resources and reserves estimates provided in this Presentation have been prepared and presented in accordance with the standards and classifications of the

regulations of certain other jurisdictions, including the regulations of the U.S. Securities Exchange Commission (the “SEC”) with respect to registration statements and other

documents filed with the SEC. Among other things, in accordance with the JORC Code, this Presentation provides certain mineral resources estimates classified as “inferred”,

“indicated” or “measured”, which differ in significant respects from “probable” and “proven” mineral reserves estimates and are not disclosed in certain jurisdictions, including in

SEC filings. There can be significant uncertainty as to whether mineral resources can ever be feasibly and commercially mined. For further explanation of the JORC Code, see

the JORC website at www.jorc.org.

Diamond supply In next decade global diamond production is expected to grow with 1.6% CAGR

During the crisis, in 2009, world diamond production dropped by 26% mainly due to De Beers production cut

In the medium term global diamond production is expected to grow with 4.7% CAGR due to rebound of production mainly at

Grib and Karpinskogo-1 (Russia), Argyle (Australia) and Gahcho Kue (Canada)

After 2018, global diamond production is expected to decline with -2.0% CAGR mainly because of Argyle (Rio Tinto), Diavik

(60% Rio Tinto and 40% Dominion Diamond Corp.) and Ekati (80% Dominion Diamond Corp.) depletion
