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 the 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, financial analysis of the project, commencement of
operations, 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.

ORGANIC GROWTH
Under-Explored Greenstone Belt

26. Planning for Organic Growth
5 Year Plan for Successful Organic Growth
Large prospective land position of approx. 566 km2
• Two main gold structures with total strike length of >80km
• Continue focus on Detour Lake deposit extension (northern
structure i.e. Block A)
• Test targets on structure south of Detour Lake
Future objectives
 Grow reserve base to +20 M oz (@ US$850/oz)
 Increase mill throughput to above 75,000 tpd for gold production
output of +800,000 oz/yr
 Find high-grade ore near-surface within trucking distance to
supplement mill
