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; timeline for the

life of mine plan update, second test for the processing of fines, and exploration program; and opportunities to optimize the mine operation.

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 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 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 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, 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 loss and adjusted basic 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 loss is defined as net 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

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.

1. Mineral reserves calculated using a gold price of US$1,000/oz; mineral resources calculated using US$1,200/oz. Foreign exchange

rate of C$1.03 to US$1.00 (refer to the “Detour Lake Mine NI 43-101 Technical Report dated February 4, 2014).

2. Mineral reserves estimated using a 4% dilution at 0.20 g/t Au and 5% ore loss.

3. Based on an elevated cut-off grade of 0.5 g/t Au for Detour Lake and cut-off grade of 0.6 g/t Au for Block A.

4. Mineral resources are exclusive of mineral reserves. Mineral resources that are not mineral reserves do not have demonstrated

economic viability. Mineral reserves and resources are compliant with CIM definitions.

5. Totals may not add due to rounding.
