CANADA’S NEXT INTERMEDIATE GOLD PRODUCER

Corporate Presentation

March 27, 2013

Forward Looking Information 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 commissioning of

the second production line, commencement of commercial production, completing a pre-feasibility study on Block A, 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, ramp-up of operations, future operating plans,

potential expansion opportunities, and plans for organic growth. 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.

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 September 4, 2012, Detour Gold announced an updated mine production plan for the Detour Lake project. The NI 43-101

compliant Technical Report for this update was filed on SEDAR on October 18, 2012. The following QPs participated in this

update: BBA Inc., under the direction of André Allaire, Eng., Vice-President, Markets – Mining and Metals and Patrice Live,

Eng., Mining Manager; SGS Canada Inc., under the direction of Michel Dagbert, Eng., Senior Geostatistician and Maxime

Dupéré, P.Geo., Senior Geologist; and AMEC Environment & Infrastructure, a Division of AMEC Americas Limited, David G.

Ritchie M.Eng., P.Eng, Senior Associate Geotechnical Engineer.
