This presentation contains certain forward-looking information and forward-looking statements, as defined in applicable securities laws (collectively referred to herein as “forward-

looking statements”). Forward-looking statements relate to future events or future performance and reflect current expectations or beliefs regarding future events and include, but

are not limited to, statements with respect to: (i) the amount of mineral resources and mineral reserves and exploration targets; (ii) the amount of future production over any period;

(iii) net present value and internal rates of return of mining operations; (iv) assumptions relating to recovered grade, average ore recovery, internal dilution, mining dilution and other

mining parameters set out in the technical reports, studies and disclosure of the Company; (v) assumptions relating to revenues, operating cash flow and other revenue metrics set

out in the Company’s disclosure materials; (vi) mine expansion potential and expected mine life; (vii) expected time frames for completion of permitting and regulatory approvals;

(viii) future capital and operating expenditures; (ix) future exploration plans; (x) future gold prices; and (xi) sources of and anticipated financing requirements. All statements other

than statements of historical fact are forward-looking statements. Often, but not always, forward-looking statements can be identified by the use of words such as “plans”, “expects”,

“is expected”, “budget”, “scheduled”, “estimates”, “continues”, “forecasts”, “projects”, “predicts”, “intends”, “anticipates”, “targets”, or “believes”, or variations of, or the negatives of,

such words and phrases or state that certain actions, events or results “may”, “could”, “would”, “should”, “might” or “will” be taken, occur or be achieved. Forward-looking statements

involve known and unknown risks, uncertainties and other factors, which may cause actual results to differ materially from those anticipated in such forward-looking statements. The

forward-looking statements in this presentation speak only as of the date of this presentation or as of the date or dates specified in such statements.

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, risks relating to variations in recovered grades and mining dilution, variations in rates of recovery, changes or delays in mining development and

exploration plans, the success of mining, development and exploration plans, changes in project parameters, risks related to the receipt of regulatory approvals, 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

2016 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 and production schedule and related costs, dilution control;

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 timing and results of consultations with the Company’s Aboriginal partners; the supply and availability of consumables

and services; the exchange rates of the Canadian dollar to the U.S. dollar; energy and fuel costs; required capital investments; estimates of net present value and internal rate of

returns; the accuracy of reserve and resource estimates, production estimates and capital and operating cost estimates and the assumptions on which such 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 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 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.

The Company believes the measure all-in sustaining costs 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.

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

general and administration, bullion shipment, refining, agreements with Aboriginal communities, capital costs (including closure costs) and net of silver sales. The Company

calculates total site costs per ounce as the sum of total site costs (as described above) divided by the total gold ounces sold. Gold ounces produced is noted before delivering

the royalty in kind ounces.

IFRS Measures The Company has included IFRS measure in this presentation: Free cash flow before financing activities, which is calculated as cash flow from operations less cash flow from

investing activities. It provides useful information to management and investors as an indicator of the cash generated from the Company’s operations before consideration of

how those activities are financed.

Year-end 2017 Reserves & Resources Notes:

1. The Company’s mineral resources and

reserves conform with generally accepted

definitions and guidelines given in the

Canadian Institute of Mining, Metallurgy

and Petroleum (CIM) Standards on

Mineral Resources and Mineral Reserves

as required by NI 43-101.

2. Mineral reserves were estimated using a

gold price of US$1,000/oz and mineral

resources were estimated using a gold

price of US$1,200/oz at a US$/C$

exchange rate of 1.10.

3. Mineral reserves and resources were

based on a cut-off grade of 0.50 g/t Au.

4. LG Fines (sourced from material grading

0.40-0.50 g/t Au) classified as Measured

and Indicated were reported as Probable

mineral reserves and included in the mine

plan.

5. Further information, including key

assumptions, parameters, and methods

used to estimate mineral resources and

mineral reserves are described in the

Technical Report on the Detour Lake

operation, dated March 22, 2017.

6. Mineral resources are reported exclusive

of mineral reserves. Mineral resources that

are not mineral reserves do not have

demonstrated economic viability. Mineral

resources are constrained within an

economic pit shell.

7. Totals may not add due to rounding.
