Building Canada’s Largest Gold Mine Production Early 2013

Corporate Presentation

June 18-22, 2012

© 2011 Detour Gold All Rights Reserved. 2

This presentation contains certain forward-looking information as defined in applicable securities laws (referred to herein as “forward-

looking statements”). Specifically, this presentation contains forward-looking statements regarding the reserve and resource

estimates, ore grade, expected mine life, anticipated gold production, gold recovery, cash operating costs and other costs, capital

costs, sensitivity to metal prices and other sensitivities, financial analysis of the project, commencement of operations, potential

expansion opportunities, plans for organic growth and expected drilling activities. Forward-looking statements involve known and

unknown risks, uncertainties and other factors which are beyond Detour Gold’s ability to predict or control and may cause Detour

Gold’s actual results, performance or achievements to be materially different from any of its future results, performance or

achievements expressed or implied by forward-looking statements. These risks, uncertainties and other factors include, but are not

limited to, gold price volatility, changes in debt and equity markets, the uncertainties involved in interpreting geological data,

increases in costs, environmental compliance and changes in environmental legislation and regulation, interest rate and exchange

rate fluctuations, general economic conditions and other risks involved in the gold exploration and development industry, as well as

those risk factors discussed in the section entitled “Description of Business - Risk Factors” in Detour Gold’s 2011 AIF and in the

continuous disclosure documents filed by Detour Gold on and available on SEDAR at www.sedar.com. Such forward-looking

statements are also based on a number of assumptions which may prove to be incorrect, including, but not limited to, assumptions

about the following: the supply and demand for gold, and the level and volatility of the price of gold; the availability of financing for

exploration and development activities; the estimated timeline for the development of the Detour Lake gold project; the expected

mine life; anticipated gold production; gold recovery; the development schedule; cash operating costs and other costs; the financial

analysis for the project; capital costs; sensitivity to metal prices and other sensitivities; the accuracy of reserve and resource

estimates and the assumptions on which the reserve and resource estimates are based; the receipt of necessary permits; market

competition; ongoing relations with employees and impacted communities; and general business and economic conditions.

Accordingly, readers should not place undue reliance on forward-looking statements. The forward-looking statements contained

herein are made as of the date hereof, or such other date or dates specified in such statements. Detour Gold undertakes no

obligation to update publicly or otherwise revise any forward-looking statements contained herein whether as a result of new

information or future events or otherwise, except as may be required by law. If the Company does update one or more forward-

looking statements, no inference should be drawn that it will make additional updates with respect to those or other forward-looking

statements.

Forward Looking Information


Information Concerning Estimates of Mineral Reserves and Resources

The mineral reserve and resource estimates reported in this presentation were prepared in accordance with Canadian National

Instrument 43-101Standards of Disclosure for Mineral Projects (“NI 43-101”), as required by Canadian securities regulatory

authorities. For United States reporting purposes, the United States Securities and Exchange Commission (“SEC”) applies different

standards in order to classify mineralization as a reserve. In particular, while the terms “measured,” “indicated” and “inferred” mineral

resources are required pursuant to NI 43-101, the SEC does not recognize such terms. Canadian standards differ significantly from

the requirements of the SEC. Investors are cautioned not to assume that any part or all of the mineral deposits in these categories

constitute or will ever be converted into reserves. In addition, “inferred” mineral resources have a great amount of uncertainty as to

their existence and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred

mineral resource will ever be upgraded to a higher category. Under Canadian securities laws, issuers must not make any disclosure

of results of an economic analysis that includes inferred mineral resources, except in rare cases.

On January 31, 2011, Detour Gold announced an updated mineral resource and reserve estimate. The following QPs participated in

this update: Michel Dagbert, Eng., Senior Geostatistician and André Laferrière, P. Geo., Senior Geologist of SGS Canada Inc.

(mineral resources); and André Allaire, Eng., Director Mining and Metals and Patrice Live, Eng., Mining Manager of BBA Inc (mineral

reserve). The NI 43-101 compliant Technical Report for this update was filed on SEDAR on March 15, 2011.

On January 25, 2012, Detour Gold announced a mineral resource and reserve update. The following QPs participated in this update:

Michel Dagbert, Eng., Senior Geostatistician of SGS Canada Inc (mineral resources) and Patrice Live, Eng., Mining Manager of BBA

Inc (mineral reserves).
