Forward Looking Information This presentation contains certain forward-looking information and statements as defined in applicable securities law (referred to herein as

“forward-looking statements”). Forward-looking statements include, but are not limited to, statements with respect to Detour Gold’s future

financial or operating performance; guidance for production, total cash costs, all-in sustaining costs, capital costs, deferred stripping costs,

exploration costs; expected throughput, mining and recovery rates; expected future production and mining activities; opportunities to

optimize the mine operation; the mine plan and economic analysis of the Detour Lake mine including, but not limited to, the life of mine plan,

the waste to ore ratio, processing and production rates, grades, metallurgical recovery rates, operating and sustaining capital costs, and the

projected life of mine, opportunities to optimize the mine operation; the success and continuation of exploration activities, the future price of

gold, reclamation obligations, government regulations and environmental risks.

Forward-looking statements involve known and unknown risks, uncertainties and other factors which may cause 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, assumptions and parameters underlying the

life of mine update not being realized, a decrease in the future gold price, discrepancies between actual and estimated production, changes

in costs (including labour, supplies, fuel and equipment), changes to tax rates; environmental compliance and changes in environmental

legislation and regulation, 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 2013 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 sustaining capital

costs; the Company’s ability to attract and retain skilled staff; sensitivity to metal prices and other sensitivities; the supply and demand for,

and the level and volatility of the price of, gold; 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.

All forward-looking statements in this presentation are necessarily based on opinions and estimates made as of the date such statements

are made and are subject to important risk factors and uncertainties, many of which cannot be controlled or predicted. Detour Gold and the

Qualified Persons who authored the associated Technical Report undertake 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.

Notes to Investors

The mineral reserve and resource estimates reported in this presentation were prepared in accordance with Canadian National Instrument 43-101 Standards 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 February 4, 2014, Detour Gold announced an updated life of mine plan for the Detour Lake mine. The NI 43-101 compliant Technical Report for this update was

filed on SEDAR on February 4, 2014. The following QPs participated in this update: BBA Inc., under the direction of André Allaire, Eng., Acting President and CEO

and Patrice Live, Eng., Director Mining; SGS Canada Inc., under the direction of Yann Camus, Eng., Project Engineer, 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

and Geotechnical Engineering Group Manager.

The scientific and technical content of this presentation has been reviewed, verified and approved by Drew Anwyll, P.Eng., Senior Vice President Technical

Services, a Qualified Person as defined by Canadian Securities Administrators National Instrument

43-101 “Standards of Disclosure for Mineral Projects”.

Information Containing Estimates of Mineral Reserves and Resources

Non-IFRS Financial Performance Measures The Company has included non-IFRS measures in this presentation: total cash costs and all-in sustaining costs. The Company believes that these measures, in

addition to conventional measures prepared in accordance with IFRS, provide investors an improved ability to evaluate the underlying performance of the Company.

The non-IFRS measures are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance

prepared in accordance with IFRS. These measures do not have any standardized meaning prescribed under IFRS, and therefore may not be comparable to other

issuers. Other companies may calculate these measure differently.

Detour Gold reports total cash costs on a sales basis. Total cash costs per gold ounce include production costs such as mining, processing, refining and site

administration, less non-cash share-based compensation and net of silver sales divided by gold ounces sold to arrive at total cash costs per gold ounce sold.

Production costs are exclusive of depreciation and depletion. Production costs include the costs associated with providing the royalty in kind ounces.

Starting in 2015, the Company will report “all-in sustaining costs”. The Company believes this measure more fully defines the total costs associated with producing

gold. The Company calculates all-in sustaining costs per ounce of gold sold as the aggregate of total cash costs (as described above), share-based compensation,

corporate general and administrative expense, exploration and evaluation expenses that are sustaining in nature, reclamation cost accretion, sustaining capital and

deferred stripping costs.

The following items are excluded from all-in sustaining costs: non-sustaining capital expenditures and exploration costs that are expected to materially increase

production, financing costs and tax expense. Consequently, this measure is not representative of all of the Company’s cash expenditures. In addition, the

Company’s calculation of all-in sustaining costs does not include depletion and depreciation expense.
