VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - May 17, 2007) - Detour Gold Corporation (TSX:DGC) ("Detour Gold" or the "Company") is pleased to report the drill results of an additional 10 holes from its ongoing 50,000 metre drilling program at its Detour Lake property in northern Ontario. The Company has four drill rigs operating at the site and has completed 96 holes totaling 35,212 metres as of May 15, 2007. Results for the first 10 holes were released on April 11, 2007.
The assay results for the 10 holes reported today continue to confirm the continuity of the gold mineralization, which is expected to expand the current near-surface resource of 1.4 million ounces in the indicated category (20.0 million tonnes grading 2.14 g/t) and 2.0 million ounces of gold in the inferred category (35.4 million tonnes grading 1.80 g/t). The mineral resource is contained within two open pits (West Pit and Calcite Zone), based on a US$450 per ounce gold price, located in the area of the former Detour Lake mine, which produced 1.8 million ounces from 1983 to 1999.
Holes DG-07-11, 12, 14, 15, 18, 28, 40 and 40A were drilled between the two US$450 pit shells (Gap Zone) and holes DG-07-16 and 19 were drilled within the unestimated (waste) portion of the US$450 pit shell (West Pit).
Significant gold intercepts (uncut) include:
Gap Zone
- 3.64 g/t over 23.0 m in DG-07-011
- 3.03 g/t over 15.5 m and 2.29 g/t over 13.0 m in DG-07-012
- 5.09 g/t over 7.0 m in DG-07-14
- 3.15 g/t over 10.0 m and 3.10 g/t over 13.0 m in DG-07-15
- 12.58 g/t over 14.0 m and 4.40 g/t over 15.0 m in DG-07-18
- 3.38 g/t over 13.0 m and 3.61 g/t over 21.0 m in DG-07-28
West Pit
- 10.67 g/t over 10.0 m, 36.74 g/t over 7.0 m, 14.28 g/t over 7.0 m, 15.06 g/t over 6.0 m in DG-07-16
- 3.17 g/t over 23.0 m in hole DG-07-19
The gold mineralization occurs within an east-west 200 metre wide corridor, which extends from the West Pit to the Calcite Zone resource blocks (a distance of 2.5 kilometres). The mineralized corridor remains open west of the Calcite Zone. The corridor occurs within an assemblage of massive and pillowed volcanic flows located on the north side (hanging wall) of a major contact with volcanoclastic and ultramafic rocks. This contact is marked by a zone of strong local shearing and hydrothermal alteration referred to as the chert marker horizon (CMH). Gold mineralization within the corridor typically consists of multiple, subvertical, five to 25 metres wide zones grading between 1.0 to 3.0 g/t gold. Higher grade gold mineralization is generally characterized by potassic alteration, and an increased percentage of sulphide minerals and quartz veining.
The primary objective of the Phase I drilling program (50,000 metres) is to expand beyond the current near-surface resource and convert a large portion of the inferred resources to the indicated category with a 40 metre east-west and 80 metre north-south grid. The drilling is focusing between surface to 350 metres over a strike length of more than two kilometres.
The current program is expected to be completed this summer. The Company plans to start a feasibility study in June 2007 and update the current mineral resource in September 2007. Details on the current mineral resource are available in the Detour Lake Project December 2006 Technical Report posted on the Company's website or on SEDAR.
Complete tables of results, surface and longitudinal plans and cross-sections for the Detour Lake deposit are posted on the Company's website www.detourgold.com/Projects/Detour Lake or on the home page "Explore Detour Lake".
Detour Gold's exploration program is being managed by Project Manager, Mr. Roger Aubertin, P.Eng., a Qualified Person within the meaning of National Instrument 43-101. Mr. Aubertin has verified and approved the data disclosed in this release, including the sampling, analytical and test data underlying the information.
Samples are prepared and assayed at SGS Minerals Services in Don Mills, Ontario, Canada. Analysis for gold is done on sawn half core samples using fire assay (AA finish). Samples with higher grade gold (greater than 5 g/t) are re-assayed using the pulp and metallics procedures. Standard reference materials, blank and field duplicate samples are inserted prior to shipment from site to monitor the quality control of the assay data. For additional information on Quality Assurance and Quality Control, refer to the press release dated April 11, 2007.
Forward-Looking Information
Certain statements herein may contain forward-looking information within the meaning of applicable securities laws. Forward-looking information appears in a number of places and can be identified by the use of words such as "intends" or variations of such words and phrases or statements that certain actions, events or results "may", "could", "would", "might" or "will" be taken, occur or be achieved. Forward-looking information includes statements regarding the Company's exploration plans with respect to the Property and the estimation of mineral resources and are subject to such forward-looking risks, uncertainties and other factors which may cause the Company's actual results, performance or achievements, or industry results, to be materially different from any future results, performance or achievements expressed or implied by such forward-looking information. Such risks include gold price volatility, change in equity markets, the uncertainties involved in interpreting geological data, increase in costs and exchange rate fluctuations and other risks involved in the gold exploration and development industry as well as those risk factors discussed under "Risk Factors" in the Company's final prospectus dated January 22, 2007 available at www.sedar.com. There can be no assurance that a forward-looking information referenced herein will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements or information.

Information Concerning Estimates of Mineral Resources
This news release uses the terms 'indicated' and 'inferred' resources. Detour Gold advises investors that although these terms are recognized and required by Canadian regulations (under National Instrument 43-101 Standards of Disclosure for Mineral Projects), the U.S. Securities and Exchange Commission does not recognize them. Investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into reserves. In addition, 'inferred resources' have a great amount of uncertainty as to their existence, and 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 rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, or economic studies except for Preliminary Assessment as defined under 43-101. Investors are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally mineable.
