Bank of America Merrill Lynch

Canada Mining Fireside Chat Event Toronto – September 8, 2016

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 strategic focus; 2016

guidance (gold production, total cash costs, all-in sustaining costs, and sustaining capital); refinancing <$300 million of the Convertible

Notes before due date; expected future production and mining activities, including development plan for West Detour; life of mine plan;

decision to proceed with underground exploration program for Zone 58N in Q4 2016; and continuation of exploration activities.

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 2015 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 amounts are in US dollars except as noted.

Notes to Investors

Qualified Persons

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”.

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-

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.

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.

Year-end 2015 Reserves & Resources Notes:

1. Mineral resources and reserves were

completed by Detour Gold in conformity

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 $1,000/oz and mineral

resources were estimated using a gold

price of $1,200/oz at a US$/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. Mineral reserves included an average

mining dilution of 5.3% from 2016 to 2018

and 4% for 2018+, at a diluting grade of

0.20g/t Au. Mining ore loss of 5% also

included.

5. Only Probable LG Fines scheduled in the

mine plan were reported as mineral

reserves. The LG fines reserves were

based on a cut-off grade of 0.40 g/t Au.

6. Mineral resources are reported exclusive

of mineral reserves. Mineral resources

that are not mineral reserves do not have

demonstrated economic viability.

7. Totals may not add due to rounding.
