The project remains on budget and on schedule for gold production to start in the first quarter of 2013. All dollar amounts are in Canadian dollars.

The following project development milestones have recently been achieved:

--  Project construction reached 60% completion mark on March 31, 2012

Gerald Panneton, President and CEO of Detour Gold commented, "The Detour Lake project construction is advancing as planned with no change in the forecast capital expenditures of $1.45 billion. The Company has sufficient cash to complete the project construction. We are on schedule for gold production to commence in the first quarter of 2013."

Capital Expenditures

Pre-production capital cost estimates for Detour Lake remain unchanged at $1.45 billion, of which approximately $736 million has been spent as of March 31, 2012. Approximately $1.17 billion of the total $1.45 billion of project expenditures has been committed. To date, 98% of all contracts have been awarded. The Company has approximately $866 million in cash and short-term investments, sufficient to fully finance the remaining project expenditures.

Construction Activities

The process plant building was completely enclosed in December and all MPEI (mechanical, piping, electrical and instrumentation) contractors are now mobilized at site. The major mill grinding components, including the gyratory crusher, secondary crushers, SAG and ball mills and motors are all at site. Status of construction progress has now reached 60% completion and includes:

--  All 20 leach tanks have been installed
--  Secondary crusher building has been completed and transferred to MPEI
--  Installation of the first line of SAG and ball mills is advancing well
    and installation of the second line has commenced
--  Installation of CIP tanks and other mechanical equipment such as pumps,
    compressors, screens and HVAC (heating, ventilation, and air
    conditioning) is well underway
--  Primary crusher structure nearing completion
--  Truck wash facility is commissioned and operational

Construction of the second 45 kilometre segment of the 230 kV powerline between Pinard and Island Falls was completed in March. Hydro One is expected to connect the powerline to the grid in the third quarter of 2012, in advance of the commissioning schedule for the mills. While the project site is already connected on 115 kV, this last connection will deliver up to 100 MW of electricity.

Pre-production Mining Activities

The 2012 pre-stripping operation is underway and is supported by six haul trucks and two hydraulic shovels. With the recent addition of a second shift and a second shovel, the production rates are increasing and have now reached 70,000 tpd (tonnes per day). The Company is targeting to have up to 3 million tonnes of ore available for processing prior to the commencement of operations.

In preparation for the 2013 production plan, an additional 12 haulage trucks and two large cable shovels are expected to arrive during the year. This will bring the total at site to 20 haulage trucks with four shovels (two of 34 m3 and two of 48 m3). The delivery of the haulage trucks has started and three are now being assembled. The first of the two large cable shovels (48 m3) is expected to be operational by late summer. A significant portion of these deliveries will be leased under the Company's US$150 million lease facility with CAT Finance.

Civil construction of the first cell of the Tailings Management Area continues to advance on schedule.

Start of Commissioning Activities

The construction team delivered the first permanent maintenance facility to the commissioning team at the end of March. The truck wash facility is now fully operational.

In addition, Detour Gold has commissioned three of the four wings (300 of 400 en-suite rooms) of the permanent camp, which will allow for construction activities to peak this summer with up to 1,500 rooms being available.
