Explore Detour Lake

2008 Drilling Program

In 2008, the Company completed 121,506 metres of drilling in 316 holes and 231,104 metres in 621 holes on the Detour Lake deposit since it acquired the project in early 2007. Assays are pending for approximately 36,400 metres of drilling. The drilling has been suspended for the holidays and is scheduled to resume on January 5, 2009.

The mineral resource update of July 2, 2008 included only 53% of the drilling completed to date. Results from the drilling program are continuing to indicate additional gold mineralization within and outside the US$700 pit shell (see Press Release July 2, 2008), which should positively impact the final pit design for the feasibility study expected in 2009.

July 2008 Mineral Resource

On July 2, 2008, Detour Gold reported an updated National Instrument 43-101 compliant mineral resource estimate for its Detour Lake project in northern Ontario based on a detailed engineered pit design.

The updated resource estimate included the historical drilling, Phase I drill results (49,322 metres) and an additional 73,469 metres of diamond drilling from its ongoing Phase II program (representing 54% of Phase II). Based on a cut-off grade of 0.50 g/t gold and a gold price of US$700 per ounce, the in-pit resources included in a detailed engineered pit design are as follows:

1. The mineral resources are classified as measured, indicated and inferred, and comply with the CIM mineral resource definitions referenced in National Instrument 43-101.
2. Base case assumes a gold price of US$700/oz gold and $US exchange rate of $1.10.
3. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
4. The quantity and grade of reported inferred resources in this estimation are conceptual in nature and there has been insufficient exploration to define these inferred resources as an indicated or measured resource and it is uncertain if further exploration will result in upgrading them to an indicated or measured resource category.

Pit sensitivity analysis, using the same identical parameters, was carried out using a gold price of US$575 and US$825 per ounce with a cut-off grade of 0.60 g/t and 0.40 g/t gold, respectively. Results of this study are presented below.

1. The mineral resources are classified as measured, indicated and inferred, and comply with the CIM mineral resource definitions referenced in National Instrument 43-101.
2. Base case assumes a gold price of US$700/oz gold and $US exchange rate of $1.10.
3. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
4. The quantity and grade of reported inferred resources in this estimation are conceptual in nature and there has been insufficient exploration to define these inferred resources as an indicated or measured resource and it is uncertain if further exploration will result in upgrading them to an indicated or measured resource category.

The mineral resource increase is largely due to:

• An additional 73,469 metres of drilling completed throughout the deposit, with a focus in the Calcite Zone (western end); also, the 40 metre by 40 metre drill spacing (from a 80 metre drill spacing) has successfully improved the continuity of the deposit;
• Discovery of more mineralized zones in the hanging wall, north of the known 200 metre wide corridor;
• Addition of known mineralization that was previously drilled (prior to Detour Gold) into the new pit shell (below the previous 2007 US$575 pit shell);
• Increase in search radius for indicated and inferred resources as a result of better continuity; and
• Gold price increase from US$575 to US$700 per ounce with a cut-off grade of 0.50 g/t.

The proposed open pit extends 2.7 kilometres in length and up to 650 metres in depth. There is excellent potential for additional mineralization along strike, especially west of the Calcite Zone for several kilometres. The mineralized system has also not been fully tested to the north in the hanging wall outside of the main 200 metre wide corridor. The deposit remains open below the former open pit where significant gold mineralization was intersected in the footwall of the chert marker horizon (CMH) (i.e. hole DG-07-194A).
