Detour Gold Reports High Grade Gold Intersections in the Lower Detour Area of Its Detour Lake Property

TORONTO, ONTARIO--(Marketwired - June 2, 2014) - Detour Gold Corporation (TSX:DGC) ("Detour Gold" or the "Company") reports assay results from its 2014 exploration drilling program in the Lower Detour Lake area located approximately 6 kilometres south of the Detour Lake gold mine on its 100% owned Detour Lake property. The Company extended its initial 8,000 metre drilling program to nearly 15,000 metres as a result of encouraging results and a longer winter drilling season. The Company completed 14,874 metres in 40 holes and has received assay results for all significant intersections of the program.

The Company has identified a significant mineralized system to the north of Zone 75 in following up a high-grade intercept of 17.3 g/t over 4.4 metres (DLD-13-075, last hole of the 2013 drilling program). This east-west mineralized zone (referred to as Zone 58N) was tested over a length of 450 metres by 28 holes totaling 10,888 metres. The mineralized system has a maximum width of 120 metres and narrows to less than 15 metres to the west and east. It has been tested from surface to a depth of approximately 300 metres and it remains open to the west and down dip. 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 10% pyrite and multiple occurrences of visible gold. The results suggest that the grade and continuity of the gold mineralization may improve at depth.

"Confirming high-grade potential within trucking distance of the processing plant only after our second exploration drilling program and with minimal expenditures demonstrates the tremendous potential of our large land package," said Paul Martin, President and CEO of Detour Gold. "Our team is excited about the prospects for success over the coming years. In the coming months, the Company will complete a detailed geological and structural interpretation exercise of the Lower Detour area in preparation for the next winter drilling campaign."

Highlights from Zone 58N include (uncut assays reported) (from west to east):

• 9.69 g/t over 30.3 metres (hole DLD-14-105)
• 11.82 g/t over 32.4 metres (hole DLD-14-103)
• 12.74 g/t over 28.0 metres (hole DLD-14-110, 80 metres up dip from DLD-14-103)
• 5.67 g/t over 23.0 metres and 5.04 g/t over 16.0 metres (hole DLD-14-112)
• 9.20 g/t over 22.0 metres (hole DLD-14-116)
• 2.55 g/t over 31.1 metres (hole DLD-14-120)

Gold mineralization was also encountered in Zone 75 (20 to 50 metres south of Zone 58N described above). This mineralized zone is characterized by strongly sheared and altered mafic volcanics and feldspar porphyry dykes containing quartz veins and up to 25% sulphides.

Highlights from Zone 75 include:

• 4.31 g/t over 7.3 metres (hole DLD-14-111)
• 10.82 g/t over 7.0 metres (hole DLD-14-088)
• 7.41 g/t over 5.1 metres (hole DLD-14-100)

The Company has also completed 3,985 metres in 12 holes testing mainly geophysical (IP) anomalies over a strike length of 5 kilometres in the Lower Detour area. With only partial assays available, only minor pyrite and/or pyrrhotite with no significant gold mineralization were encountered in the holes.

All drill hole data, including drill hole location map and cross sections are posted on the Company's website under Projects/Detour Lake Exploration: Regional.

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. No significant gold mineralization was intersected in the other drill holes. 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 (AA finish). Samples with higher grade gold (>3 g/t) or with visible gold are re-assayed using the pulp and metallics procedures. The Company's quality control checks include the insertion of standard reference materials and blank samples to monitor the accuracy of the assay data.
