Forward Looking Information
This presentation contains certain forward-looking information as defined in applicable securities laws (referred to herein as “forward-looking
statements”). Specifically, this presentation contains forward-looking statements regarding 2013 guidance for gold production and total cash
costs, reserve and resource estimates, ore grade, expected mine life, average annual gold production, gold recovery, cash operating costs
and other costs, sensitivity to metal prices and other sensitivities, ramp-up of operations, mining rates reaching approximately 200,000 tpd
by year-end 2013, future operating plans, potential expansion opportunities, and plans for organic growth which includes growing mineral
reserves to more than 20 million ounces. 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, 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 2012 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 schedule; 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 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. 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
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.
On September 4, 2012, Detour Gold announced an updated mine production plan for the Detour Lake project. The NI 43-101 compliant
Technical Report for this update was filed on SEDAR on October 18, 2012. The following QPs participated in this update: BBA Inc., under
the direction of André Allaire, Eng., Vice-President, Markets – Mining and Metals and Patrice Live, Eng., Mining Manager; SGS Canada
Inc., under the direction of Michel Dagbert, Eng., Senior Geostatistician and Maxime Dupéré, P.Geo., Senior Geologist; and AMEC
Environment & Infrastructure, a Division of AMEC Americas Limited, David G. Ritchie M.Eng., P.Eng,
Senior Associate Geotechnical Engineer.
Information Containing Estimates of Mineral Reserves and Resources
Note Regarding Certain Measures of Performance
This presentation presents estimates of future “cash operating costs per tonne milled”, “cash operating costs per ounce of gold produced”,
“total cash costs per tonne milled” and “total cash costs per ounce of gold produced” which are not recognized financial measures under
GAAP. These non-GAAP financial measures are intended to provide additional information to investors. However, they do not have a
standardized meaning under GAAP and may not be comparable to similar measures presented by other gold producers. The estimates of
future cash operating costs per tonne milled and future cash operating costs per ounce of gold produced include estimated mining,
processing and site administration costs divided by estimated tonnes milled or gold ounces produced, respectively. The estimates of future
total cash costs per tonne milled and future total cash costs per ounce of gold produced include estimated mining, processing, site
administration, royalty and refining costs net of estimated silver by-product credits divided by estimated tonnes milled or gold ounces
produced, respectively. These future estimates are based upon the cash operating costs per tonne milled, the cash operating costs per
ounce of gold produced, the total cash costs per tonne milled and the total cash costs per ounce of gold produced that the Company
expects to incur to mine gold at the Detour Lake mine. Since the Detour Lake mine has not yet reached commercial production, there is no
reconciliation to actual GAAP measures provided as it is not practicable to reconcile these forward-looking non-GAAP financial measures to
the most comparable GAAP measures.
