• Gold production to start in January 2013
• Project construction reached 95% completion mark at end of October
• Mill commissioning of first production line commenced in October
• Average mining rates above 100,000 tpd during September and October
• Ore stockpile totalled 1.1 million tonnes at end of October
• Operational team now at 396 employees, ahead of schedule

Gerald Panneton, President and CEO of Detour Gold commented, “We are nearly finished with construction and I am proud of what our team has accomplished in just 24 months. The energy at site is vibrant and I would like to thank all our employees and contractors for their dedication and excellent work. We are now confident we will see the first ore in the mill circuit before year-end, almost two months ahead of the original schedule. The first gold pour is expected to occur in January 2013 and will mark a new chapter in Detour Gold’s successful history as it transitions from a developer to producer and becomes the next mid-tier gold producer in Canada.”

Detour Lake Construction 95% Complete and Plant Commissioning Starting

Construction progress is at the 95% completion mark at the end of October 2012 and the Detour Lake mining operation is approximately two months away from its first gold production. At the processing plant, the mechanical work is 98% complete, which has permitted commissioning activities to commence. Mechanical alignment of the SAG and ball mill for the first grinding line is complete. Contractor manpower has begun to ramp-down and efforts are now focused on finishing the electrical and instrumentation work.

The first cell of the tailings management area (TMA) has reached the dam level required for the 2013 operation. Dewatering of the historic Campbell pit to the TMA is progressing as planned and will reach the targeted water level well in advance of operations. The water recovery system, the tailing lines and secondary containment systems are essentially complete.

Detour Gold’s operation manpower is now at 396 employees with all senior operational management positions filled.

Pre-stripping and Mining Activities Reaches 20.3 Mt Mined

The production rates are steadily increasing and have now reached an average daily rate of more than 100,000 tpd over the last two months. As of the end of October 2012, the Company had mined over 20.3 million tonnes of material, with the majority relating to pre-stripping. Approximately 1.1 million tonnes of ore have been stockpiled for future processing, which is in line with the Company’s plan of having 2.3 million tonnes of ore at an average grade of 0.81 g/t by year-end 2012.

2013 Guidance

For 2013, the Company’s guidance remains unchanged:

• Gold production ranging between 350,000 and 400,000 ounces of gold
• Total cash costs of between $800/oz and $900/oz (to be reported after commercial production is declared)

Capital Costs Update

Pre-production capital costs are expected to finish within 3% of the project cost estimate of $1.45 billion, which dates from November 2011, one year ago. The increase is mainly associated with the acceleration of the schedule to process ore by year-end.

As of September 30, 2012, the Company had spent $1.19 billion and had approximately $348 million in cash and short-term investments, sufficient to fully finance the remaining project expenditures ($270 to $310 million). The Company expects to secure a letter of credit facility this month that will allow its letters of credit to be uncollateralized. It is also continuing to advance a senior secured credit facility to provide working capital required during the initial ramp-up period.
