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, capital costs, exploration costs; expected throughput, mining

and recovery rates; expected future production and mining activities; opportunities to optimize the mine operation; the updated 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-

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 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.,

Vice President of Operations, 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 “Total cash cost per gold ounce sold (TCC)” and “Adjusted net loss” in this presentation which are non-IFRS measures.

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 and its ability to generate operating earnings and cash flow from its mining

operations. Refer to the MD&A of June 30, 2014 or relevant period for reconciliation of these measures.

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

refining, site administration, costs associated with providing royalty in-kind ounces, and costs for agreements with Aboriginal communities, but are

exclusive of depreciation and depletion, reclamation, non-cash share-based compensation and deferred stripping. Total cash costs are reduced by

silver sales and divided by gold ounces sold to arrive at total cash costs per gold ounce sold. Further details regarding total cash costs per gold

ounce sold and a reconciliation to the nearest IFRS measures are provided in our MD&A accompanying our financial statements filed on

www.sedar.com. Total cash costs plus capex per gold ounce sold includes TCC plus sustaining capital and deferred stripping divided by gold

ounces sold. These 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 this measure differently.
