Detour Gold Update on Detour Lake Project Construction and Increased Exploration Budget to $20 Million

TORONTO, ONTARIO--(Marketwire - June 22, 2011) -Detour Gold Corporation (TSX:DGC) ("Detour Gold" or the "Company") reports on the construction progress and 2011 exploration program at its flagship Detour Lake gold project in northeastern Ontario. All dollar amounts are in Canadian dollars.

Detour Lake Construction Update

Detour Gold initiated infrastructure construction activities at the Detour Lake site in November 2010, following receipt of approvals from the provincial government. The development of the mine and construction of the processing plant are proceeding in accordance with the planned schedule. AMEC has operational responsibility for the procurement and construction management services for the project. There are currently approximately 902 construction personnel on site. Personnel at site is expected to reach in excess of 1,000 people at the peak of construction. Overall construction of the project is now approximately 25% complete.

• Completion of the first 135 kilometre powerline section between the project site and Island Falls (two months ahead of schedule)
• Construction camp is currently at 1,000 rooms; an additional 200 beds anticipated by the end of June
• Plant site earthworks are close to 70% complete
• Concrete work is approximately 30% advanced
• Detailed engineering is 70% complete
• $815.3 million has been committed towards capital expenditures of which $245.6 million has been spent

The concrete work for the process plant building is advancing and the construction team is on schedule to initiate steel erection in late June. Installation of the leach tanks and the electric sub-station near the processing plant is underway. Dam construction around the existing tailings facility is scheduled to start in early July.

Purchase orders have been placed for all major equipment and the first of the initial six hauling trucks (CAT 795E) are arriving on site in July. The first RH340 shovel is scheduled to arrive in October. The SAG and ball mills will be ready to be shipped in August. The last significant contracts, the electric rope shovels and the MPEI (mechanical, piping, electrical and instrumentation), are expected to be awarded in the third quarter.

With procurement activities 85% completed, there is limited exposure for cost overrun or delivery delays for the remaining portion. The majority of contracts have been awarded at or below budget expectations.

The Project Control Estimate completed by AMEC shows total capital expenditures for the project at $1.28 billion versus the feasibility study estimate of $1.18 billion, an increase of approximately 8.5% and well within the feasibility study estimate of -10%/+15%. The increase in costs is primarily related to higher indirect costs in the areas of construction management, construction of temporary facilities and construction freight and an increase of the contingency by $12.1 million to $100.2 million. Management will make every effort to minimize contingency spending through effective construction management and cost control.

Gerald Panneton, President and CEO of Detour Gold said "We are extremely pleased with the progress we have made to date since commencing construction at the Detour Lake site. The project is currently on time and on budget. The Project Control Estimate, being well within the feasibility study estimate, demonstrates the high quality of the work that went into the feasibility study including ordering long lead equipment a year ago. The Company has currently $780 million cash on hand which, together with the US$105 million Caterpillar financing previously announced, provides us with the financing required well into 2012".

2011 Exploration Program

In May, Detour Gold increased its 2011 exploration budget from $14 million to $20 million. Exploration and drilling activities are focussing on:
