Forward-looking statements include, but are not limited to, statements with respect to full year 2015 estimated all-in sustaining costs and total cash costs, strategic focus, 2016 guidance (gold production, total cash costs, all-in sustaining costs, capital expenditures and exploration), new life of mine plan and economic analysis of the Detour Lake operation including, but not limited to, the mine plan, processing and production rates, grades, metallurgical recovery rates, operating and capital costs, the projected mine life, the net present value, opportunities to optimize the mine operation, the success and continuation of exploration activities, the future price of gold, reclamation obligations, permitting schedule, 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 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 related Technical Report and 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. 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.

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 43101. 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.

Doyle André Falzon Ingrid Hibbard Michael Kenyon Paul Martin Alex G. Morrison Jonathan Rubenstein Graham Wozniak End Notes 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, a Qualified Person as defined by Canadian Securities Administrators National Instrument 43-101 “Standards of Disclosure for Mineral Projects”. Non-IFRS Financial Performance Measures Detour Gold has included non-IFRS measures in this presentation. 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 measures differently as a result of differences in underlying principles and policies applied. All-in sustaining costs 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 below), share-based compensation, corporate general and administrative expense, exploration and evaluation expenses that are sustaining in nature, reclamation cost accretion (also known as unwinding of the discount on decommissioning and restoration provisions), sustaining capital including deferred stripping, and realized gains and losses on hedges due to operating and capital costs, all divided by the total gold ounces sold to arrive at a per ounce figure. Total cash costs are reported 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. Total site costs per ounce are reported on a produced basis in this presentation. 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 (excluding closure costs) and net of silver sales. These are exclusive of depreciation and depletion. The Company calculates total site costs per ounce as the sum of total site costs (as described above) divided by the total gold ounces produced. Gold ounces produced is noted before delivering the royalty in kind ounces. 31 End Notes 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.
