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, estimated reserves and resources at the Ekati Diamond Mine, production, capital and operating cost estimates for the Ekati Diamond Mine. Forward-looking information is based on certain factors and assumptions, including, among other things, the current mine plan the Ekati Diamond Mine; construction and exploration activities at the Ekati Diamond Mine; the timely receipt of required regulatory approvals; mining methods; currency exchange rates; estimates related to the capital expenditures required to bring the Jay pipe into production; required operating and capital costs; labour and fuel costs; world and US economic conditions; future diamond prices; and the level of worldwide diamond production. 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, risks associated with the estimates related to the capital expenditures required to bring the Jay pipe into production, risks associated with the remote location of and harsh climate at the Ekati Diamond Mine, variations in mineral reserve and mineral resource estimates, grade estimates and expected recovery rates, failure of plant, equipment or processes to operate as anticipated, risks resulting from the Eurozone financial crisis, risks associated with regulatory requirements and any delays in receiving required regulatory approvals, the risk that diamond price assumptions may prove to be incorrect, the risk of fluctuations in diamond prices and changes in US and world economic conditions, or the risk of fluctuations in the Canadian/US dollar exchange rate and cash flow and liquidity risks. Please see the Company’s most recently filed Management’s Discussion and Analysis, as well as the Company’s current Annual Information Form, both available at www.sedar.com and www.sec.gov, respectively, for a discussion of these and other risks and uncertainties involved in the Company’s operations.

Misery South and Southwest are currently inferred resources. 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.
