CANADA’S NEXT INTERMEDIATE GOLD PRODUCER

Corporate Presentation

July 10, 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 the commencement of commercial production at

the Detour Lake mine, 2013 guidance for gold production and total cash costs, reserve and resource estimates, ore grade, expected mine

life, average annual gold production, gold recovery, cash operating costs and other costs, sensitivity to metal prices and other sensitivities,

ramp-up of operations, mining rates reaching approximately 200,000 tpd by year-end 2013, future operating plans, potential expansion

opportunities, and plans for organic growth which includes growing mineral reserves to more than 20 million ounces. 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 2012 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 availability of

financing for exploration and development activities; operating and capital costs; the Company’s ability to attract and retain skilled staff; the

mine development schedule; sensitivity to metal prices and other sensitivities; the supply and demand for, and the level and volatility of the

price of, gold; timing of the receipt of regulatory and governmental approvals for development projects and other operations; the supply and

availability of consumables and services; the exchange rates of the Canadian dollar to the U.S. dollar; energy and fuel costs; the accuracy

of reserve and resource estimates and the assumptions on which the reserve and resource estimates are based; 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.

Notes to Investors

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.

Information Containing Estimates of Mineral Reserves and Resources

Note Regarding Certain Measures of Performance This presentation presents estimates of future “cash operating costs per tonne milled”, “cash operating costs per ounce of gold produced”,

“total cash costs per tonne milled” and “total cash costs per ounce of gold produced” which are not recognized financial measures under

GAAP. These non-GAAP financial measures are intended to provide additional information to investors. However, they do not have a

standardized meaning under GAAP and may not be comparable to similar measures presented by other gold producers. The estimates of

future cash operating costs per tonne milled and future cash operating costs per ounce of gold produced include estimated mining,

processing and site administration costs divided by estimated tonnes milled or gold ounces produced, respectively. The estimates of future

total cash costs per tonne milled and future total cash costs per ounce of gold produced include estimated mining, processing, site

administration, royalty and refining costs net of estimated silver by-product credits divided by estimated tonnes milled or gold ounces

produced, respectively. These future estimates are based upon the cash operating costs per tonne milled, the cash operating costs per

ounce of gold produced, the total cash costs per tonne milled and the total cash costs per ounce of gold produced that the Company

expects to incur to mine gold at the Detour Lake mine. Since the Detour Lake mine has not yet reached commercial production, there is no

reconciliation to actual GAAP measures provided as it is not practicable to reconcile these forward-looking non-GAAP financial measures to

the most comparable GAAP measures.
