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, 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.

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 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.

(equivalent to mining rates of 300,000 to 385,000 tpd)
 Include Block A as a second feed source (at earliest 2018)
 Evaluate the use of Block A pit as waste rock dump and TMA cell

Processing of Fines
Segregation of fines:
 Gold concentrates in the finer
material
 Segregation of fines allows for:
›better grade
›faster processing rates
First Test in Fall 2014:
 Positive results from first
200,000 tonnes test
› grade of 0.62 g/t = 41%
higher than avg. grade of SP
› processed at 68,000 tpd
Low-grade stockpile (avg. grade 0.44 g/t)
Natural segregation of fines
from unloading truck

20. 20
Second Test in Q3 2015:
 Started in July 2015
 Process up to 4,000 tpd
 Validate milling rate
improvement:
› Model suggests increase
of 100-125 tpoh
or 2,400-3,000 tpd for
the first 4,000 tpd added
If results are successful:
 Incorporate into LOM plan

Note: The Company has been notified by the Independent Electricity System Operator (“IESO”) of an adjustment to its electricity rebate
for the period between January 2013 and April 2015, which has resulted in an additional electricity cost of US$12.5 million (refer to Note 6i
in second quarter 2015 financial statements). The balance is payable in 20 equal monthly instalments. As per its contract with IESO, the
Company pays a maximum of C$0.05/kWh until December 2019. The Company has filed for a three-year extension of the contact.

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.
