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 2015 guidance for

production, total cash costs, all-in sustaining costs, capital costs, deferred stripping costs, and exploration costs; expected throughput,

mining and recovery rates; expected future production and mining activities; opportunities to optimize the mine operation; and timeline for

the life of mine plan update.

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 plan 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 2014 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

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.

All monetary amounts are in U.S. dollars unless otherwise stated.

Notes to Investors

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

Services, and exploration results was reviewed, verified and approved by Guy MacGillivray, P.Geo., Exploration Manager , both Qualified Person as

defined by Canadian Securities Administrators National Instrument 43-101 “Standards of Disclosure for Mineral Projects”.

Qualified Persons

Non-IFRS Financial Performance Measures The Company has included non-IFRS measures in this presentation: total cash costs, all-in sustaining costs, adjusted net loss and adjusted net loss per

share. 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 include production costs such as mining, processing, refining and site

administration, agreements with Aboriginal communities, 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. The measure also includes other mine related costs incurred such as mine standby costs and current

inventory write downs. Production costs are exclusive of depreciation and depletion. Production costs include the costs associated with providing the

royalty in kind ounces.

Commencing in 2015, the Company adopted all-in sustaining costs on a prospective basis. The Company believes this measure more fully defines the total

costs associated with producing gold. The Company calculates all-in sustaining costs as the sum 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 including deferred stripping, and realized gains and losses on hedges due to operating and capital costs, all divided by the gold

ounces sold to arrive at a per ounce figure.

Costs excluded from all-in sustaining costs are 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

calculation of all-in sustaining costs does not include depreciation and depletion expense as it does not reflect the impact of expenditures incurred in prior

periods.

Adjusted net earnings (loss) and adjusted basic earnings (loss) per share are used by management and investors to measure the underlying operating

performance of the Company. Presenting these measures from period to period helps management and investors evaluate earnings trends more readily in

comparison with results from prior periods. Adjusted net earnings (loss) is defined as net earnings (loss) adjusted to exclude specific items that are

significant, but not reflective of the underlying operations of the Company, including: fair value change of the convertible notes, the impact of foreign

exchange gains and losses, including the foreign exchange on deferred income and mining taxes, non-cash unrealized gains and losses on derivative

instruments, accretion on convertible notes, unwinding of discount on decommissioning and restoration provisions, impairment provisions and reversals

thereof, and other non-recurring items. Adjusted basic net earnings (loss) per share is calculated using the weighted average number of shares outstanding

under the basic method of loss per share as determined under IFRS.

Notes to Investors Information Containing Estimates of Mineral Reserves and Resources

The mineral reserve and resource estimates reported in this presentation were prepared in accordance with Canadian National Instrument 43-101

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.
