Detour Gold Extends High Grade Gold Mineralization at Lower Detour; Drilling Program of 30,000 Metres to Start this Summer

TORONTO, ONTARIO--(Marketwired - April 28, 2015) - Detour Gold Corporation (TSX:DGC) ("Detour Gold" or the "Company") reports assay results from its 2015 winter drilling program in the Lower Detour Lake area, located approximately six kilometres south of the Detour Lake gold mine.

Results from the eight holes totaling 5,700 metres have confirmed the continuity of the high-grade gold intercepts encountered in last year's winter drilling program. All eight holes intersected the mineralized zone at 150 to 200 metres below last year's drill holes with six of eight holes returning significant gold mineralization.

"The opportunity to identify and define a high-grade gold target is extremely valuable to us. With the success obtained from this drilling program, we now plan to initiate a much larger in-fill drilling campaign on zone 58N to better define the grade continuity of this mineralized system," said Paul Martin, President and CEO of Detour Gold. "Our team is excited about our exploration successes and looks forward to unlocking the potential of our prospective large land package."

Drilling Program Highlights

Zone 58N (uncut gold assays reported)

• 9.53 g/t over 12.0 metres, including 22.41 g/t over 5.0 metres (hole DLD-15-128)
• 5.92 g/t over 18.9 metres, including 12.30 g/t over 5.0 metres (hole DLD-15-131)
• 14.89 g/t over 4.1 metres (hole DLD-15-132)
• 4.91 g/t over 6.5 metres (hole DLD-15-134)
• 4.15 g/t over 8.7 metres (hole DLD-15-127)

To date, the east-west sub-vertical 58N mineralized zone has now been tested over a strike length of 450 metres with 36 holes totaling 16,465 metres. The higher grade gold mineralization has now been traced for approximately 250 metres along strike and from surface to a depth of approximately 550 metres. The system remains open at depth and down plunge to the east.

The gold mineralization is mainly found within the southern portion of a strongly sheared and altered feldspar porphyry intrusive containing quartz and/or quartz-tourmaline veins with up to 5% pyrite and multiple occurrences of visible gold.

With these encouraging results, the Company plans to complete a $5 million drilling program of approximately 50 drill holes totaling 30,000 metres this summer with three drill rigs. This infill program on a 50 metre spacing is expected to be sufficient to assess the underground potential of zone 58N.

Drilling to date highlights the potential for high-grade gold mineralization of the Lower Detour Deformation Zone, which extends for over 30 kilometres on the Detour Lake property. Detour Gold also completed 14,000 kilometres of high resolution airborne magnetics and over 50 kilometres of ground Induced Polarization (IP) surveys, which will further assist in delineating future targets on its 630 square kilometre property.

Technical Information

Detour Gold's drilling program is being managed by its Exploration Manager, Guy MacGillivray, P.Geo., a Qualified Person within the meaning of National Instrument 43-101. Mr. MacGillivray has verified and approved the data disclosed in this release, including the sampling, analytical and test data underlying the information. The true width of the reported intercepts is estimated to be 65 to 75% of the drilled length. Samples are prepared at ALS Laboratories in Timmins and Sudbury and assayed at their Vancouver, B.C laboratory. Analysis for gold is done on sawn half core samples (size NQ) using 50 grams fire assay (AAS finish). Samples with higher grade gold (>5 g/t) or with visible gold are re-assayed using the pulp and fire assay with gravimetric finish procedures. The Company's quality control checks include the insertion of standard reference materials and blank samples to monitor the precision and accuracy of the assay data.
