Detour Gold Extends Gold Mineralization Outside of the Current Resource at its Detour Lake Property, Northern Ontario (DG-07-01 Intersects 2.71 g/t Over 31 Metres)

TORONTO, ONTARIO--(CCNMatthews - April 11, 2007) - Detour Gold Corporation (TSX:DGC) ("Detour Gold" or the "Company") is pleased to report the drill results of the first 10 holes of a 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 66 holes totaling 24,189 metres as of March 31, 2007.

The assay results for the first 10 holes are confirming the continuity of the gold mineralization, which is expected to expand the current near-surface resource of 3.4 million ounces (indicated mineral resource of 20.0 million tonnes grading 2.14 g/t containing 1.4 million ounces of gold and an inferred mineral resource of 35.4 million tonnes grading 1.80 g/t containing 2.0 million ounces of gold). The mineral resource is contained within two open pits (West Pit and Calcite Zone) based on a US$450 per ounce gold price. All holes announced today were drilled within the unestimated (waste) portion of the US$450 pit shell (West Pit) and between the two US$450 pit shells (Gap Zone). The near-surface deposit is located in the area of the former Detour Lake mine, which produced 1.8 million ounces from 1983 to 1999.

Significant gold intercepts (uncut) include:

- 2.71 g/t over 31.0 m and 2.17 g/t over 22.0 m in DG-07-01

- 2.25 g/t over 31.1 m in DG-07-04

- 3.15 g/t over 15.0 m, 8.53 g/t over 8 m, and 2.48 g/t over 23.0 m in DG-07-06

- 2.59 g/t over 20.0 m in DG-07-13

Results from the drilling program continue to confirm that the gold mineralization occurs within an east-west, 100 to 200 metre wide corridor, which extends from the West Pit to the Calcite Zone resource blocks. The mineralized corridor remains open west of the Calcite Zone. The corridor occurs within a sequence of massive and pillowed volcanic flows located on the north side (hanging wall) of a major contact with volcanoclastic and ultramafic rocks. The 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 consists of multiple, subvertical, five to 35 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 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 resource in September 2007. Details on the current resource are available in the December 2006 Technical Report available 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".

Quality Assurance/Quality Control and Qualified Person

The drill holes reported in this press release were collared using NQ (47.6 mm) sized core. All logging and sampling is conducted by employees and contractors working for Detour Gold.

The core is photographed, logged and then marked up for sampling using standard lengths of one metre, but is locally adjusted to no less than 0.5 metre to accommodate significant geological contacts. The core is then split into two equal halves using a diamond saw. One half of the core is left in the original core box and stored in a secure location at the Detour Lake site and the other half is sampled, placed into sealed bags and stored at the site until being shipped to SGS Minerals Services in Don Mills, Ontario. At the SGS facility, the entire half-core is crushed to 90% passing 10 mesh (2 mm) and riffle split to obtain a 500 gram subsample. Each 500 gram subsample is then pulverized to 90% passing 200 mesh (75 microns) and subsampled again to obtain a 50 gram pulp. SGS Minerals Services in Toronto is accredited to ISO/IEC 17025.

Routine gold analysis is conducted by SGS at the laboratory in Toronto using fire assaying with atomic absorption finish. All samples with visible gold and all samples returning values of 5 g/t gold or greater on the first analysis are analyzed with the pulp and metallics procedures using a minimum sized 1 kilogram split of the original 10 mesh subsample. The subsamples are passed through a 150 mesh screen and then both the coarse and fine fractions are analyzed using fire assaying with atomic absorption finish. Selected samples are also analyzed later for copper using sodium peroxide fusion and inductively coupled plasma optical emission spectrometer (ICP-OES).

Quality control procedures include the systematic insertion of blanks, standards and duplicates to the sample stream by Detour Gold at the rate of one per every 40 samples. In addition, SGS inserts one preparation blank and certified reference material for every 46 samples and one duplicate every 12 samples. Data that falls outside the control limits is investigated and repeated as necessary.

Guidelines for Quality control and Quality Assurance have been provided by Lynda Bloom of Analytical Solutions Ltd.

The Detour Gold exploration program is being managed by Senior Technical Advisor, Mr. Eric Kallio, P.Geo., and, on-site, by Mr. Roger Aubertin, P.Eng., and Mr. Fred Sharpley, P.Geo., all of whom are Qualified Persons within the meaning of National Instrument 43-101. Mr. Eric Kallio has verified and approved the data disclosed in this release, including the sampling, analytical and test data underlying the information.

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 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 'measured', '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.
