2. 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 commissioning of
the second production line, securing a $90 million credit facility, commencement of commercial production, completing a pre-
feasibility study on Block A, reserve and resource estimates, ore grade, expected mine life, anticipated gold production, gold
recovery, cash operating costs and other costs, capital costs, sensitivity to metal prices and other sensitivities, ramp-up of
operations, future operating plans, potential expansion opportunities, and plans for organic growth. 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 2011 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 supply and demand for gold, and
the level and volatility of the price of gold; the availability of financing for exploration and development activities; the estimated
timeline for the development of the Detour Lake gold project; the expected mine life; anticipated gold production; gold
recovery; the development schedule; cash operating costs and other costs; the financial analysis for the project; capital costs;
sensitivity to metal prices and other sensitivities; the accuracy of reserve and resource estimates and the assumptions on
which the reserve and resource estimates are based; the receipt of necessary permits; 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.

3. NI-43 101 Disclosure
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.
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.
