Forward-looking information relates to management’s future outlook and anticipated events or results, and can include statements or information regarding
plans for mining, development, production and exploration activities at the Company’s mineral properties, sales estimates, expected sales, and expected
operating costs. Forward-looking information included in this presentation includes the estimated mine life and other plans, timelines and targets for mining,
development, permitting, production and exploration activities at the Ekati Diamond Mine and Diavik Diamond Mine, estimated reserves and resources at the
Ekati Diamond Mine and Diavik Diamond Mine, the current production forecast and capital and operating cost estimates for the Ekati Diamond Mine and the
Diavik Diamond Mine.
Forward-looking information is based on certain factors and assumptions, including, among other things, the current mine plans for each of the Diavik Diamond
Mine and the Ekati Diamond Mine; construction and exploration activities at the Company’s mineral properties; currency exchange rates; and world and US
economic conditions. While the Company considers these assumptions to be reasonable based on the information currently available to it, they may prove to be
incorrect. Forward-looking information is subject to certain factors, including risks and uncertainties, which could cause actual results to differ materially from
what the Company currently expects. These factors include, among other things, the uncertain nature of mining activities, including risks associated with
underground construction and mining operations, risks associated with joint venture operations, including risks associated with the inability to control the timing
and scope of future capital expenditures, the risk that the operator of the Diavik Diamond Mine may make changes to the mine plan and other risks arising
because of the nature of joint venture activities, risks associated with the remote location of and harsh climate at the Company’s mineral property sites, risks
resulting from the Eurozone financial crisis, risks associated with regulatory requirements, the risk of fluctuations in diamond prices and changes in US and
world economic conditions, the risk of fluctuations in the Canadian/US dollar exchange rate, and cash flow and liquidity risks. Please see the Company’s most

Mineral resources that are not mineral reserves do not have demonstrated economic viability. Inferred mineral resources are considered too speculative geologically to have
economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that this assessment will be realized.
