Detour Gold Corporation (TSX: DGC) ("Detour Gold" or the "Company") is pleased to report positive results from its infill drilling program on a 20 metre by 20 metre grid in the eastern portion of the Detour Lake deposit (West Pit area). The drilling program of 8,101 metres (53 holes) was completed in the last quarter of 2008 to infill an area of 80 metres along strike (19,420E to 19,500E) by 370 metres in width (north-south), from surface to a depth of 160 metres (referred to as the "20m X 20m Test Block").

Overall, the results of the 20m X 20m Test Block when compared to the previous 40m x 40m drill hole spacing confirm the following:
  • Approximately same number of gold ounces in measured and indicated categories
  • Slight improvement in average gold grade (measured + indicated)
  • Continuity of three main mineralized envelopes
  • Drill spacing of 40 metres by 40 metres is adequate for the deposit
The table below compares the mineral resources contained in the Test Block with a drill spacing of 20 metres versus the initial 40 metres.

(1) The mineral resource estimate uses the same parameters and methodology as the one released on July 2, 2008 for the Detour Lake deposit based on a US$700/oz gold price.


Gerald Panneton, President and CEO of Detour Gold, commented: "We are very satisfied with these 20m X 20m infill results, which add greater confidence in our understanding of the continuity of the main mineralized zones with relatively no loss in ounces in the measured and indicated categories. It further indicates the adequacy of our 40 metres drill spacing for the upcoming mineral reserve statement that will be included in the pre-feasibility study expected to be released in the second quarter of 2009."

Detour Gold has currently four drill rigs on site with two testing the footwall mineralization, from surface to 200 metres, on the south side of the former open pit and the other two completing the infill drilling further to the west.

Significant mineralized (uncut) intervals encountered in the 20m X 20m Test Block are shown below.

Detour Gold's infill drilling program is being managed by Project Manager, Mr. Roger Aubertin, P.Eng. The 20m X 20m Test Block mineral resource estimate was prepared by Thon Consulting of Smithers, British Columbia and subsequently verified by Robert Crepeau, P.Eng., consultant for Detour Gold. Both Mr. Aubertin and Mr. Crepeau are Qualified Persons within the meaning of National Instrument 43-101 and have verified and approved the data disclosed in this release.

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 (>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 ("QA/QC"), refer to the press release dated April 11, 2007.

Forward-Looking Information
This press release contains certain forward-looking information as defined in applicable securities laws (referred to herein as "forward-looking statements"). Often, but not always, forward-looking statements can be identified by the use of words such as "plans", "expects", "is expected", "budget", "scheduled", "estimates", "continues", "forecasts", "projects", "predicts", "intends", "anticipates" or "believes", or variations of, or the negatives of, such words and phrases, or statements that certain actions, events or results "may", "could", "would", "should", "might" or "will" be taken, occur or be achieved. Specifically, this press release includes forward-looking statements regarding: the Company's planned drilling program and estimate of the quantity and quality of its mineral resources. Inherent in forward-looking statements are risks, uncertainties and other factors beyond the Company's ability to predict or control. These risks, uncertainties and other factors include, but are not limited to, the uncertainties involved in interpreting geological data and other risks involved in the gold exploration and development industry as well as those risk factors listed in the Company's Annual Information Form (AIF), Item 4.4 -- "Description of Business - Risk Factors" filed on SEDAR. Readers are cautioned that the list of factors included in the AIF is not exhaustive of the factors that may affect the forward-looking statements. Actual results and developments are likely to differ, and may differ materially, from those expressed or implied by the forward-looking statements contained in this press release. Such statements are based on a number of assumptions which may prove to be incorrect, including, but not limited to, the following assumptions: the Company's exploration and development activities on the Detour Lake Property will proceed in accordance with the Company's current timetables; and the Company's resource estimates, geological and metallurgical assumptions (including with respect to the size, grade and recoverability of mineral resources) and operational and price assumptions on which the resource estimates are based, are accurate. Forward-looking statements involve known and unknown risks, uncertainties and other factors which may cause the Company'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. All forward-looking statements herein are qualified by this cautionary statement. Accordingly, readers should not place undue reliance on forward-looking statements. The Company undertakes no obligation to update publicly or otherwise revise any forward-looking statements whether as a result of new information or future events or otherwise, except as may be required by law.

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.
