Detour Gold Reports Positive Drilling Results from Lower Detour

TORONTO, ONTARIO--(Marketwired - Jul 28, 2016) - Detour Gold Corp. (TSX:DGC) ("Detour Gold" or the "Company") reports positive results from its 2016 winter drilling program at Lower Detour, which targeted Zone 58N located approximately six kilometres south of its flagship Detour Lake gold mine (refer to Table 1).

During the 2016 winter drilling program, the Company completed 36,830 metres of infill drilling in 119 holes at a 25 metre drill spacing above 250 metres and at a 50 metre spacing below 250 metres. The second phase of the infill drilling program totaling approximately 25,000 metres resumed in July.

Zone 58 N - Significant Intercepts (uncut gold assay reported)

• 35.19 g/t over 5.2 m (DLD-16-190)
• 26.38 g/t over 13.0 m, including 79.40 g/t over 4.0 m (DLD-16-205)
• 26.97 g/t over 8.0 m (DLD-16-233A)
• 10.23 g/t over 22.0 m, including 18.91 g/t over 6.0 m (DLD-16-245)
• 14.75 g/t over 22.0 m, including 34.21 g/t over 9.0 m (DLD-16-248)
• 30.79 g/t over 10.0 m, including 75.60 g/t over 4.0 m (DLD-16-250)
• 15.46 g/t over 13.0 m (DLD-16-270)
• 18.93 g/t over 13.0 m, including 57.58 g/t over 4.0 m (DLD-16-273)
• 34.98 g/t over 23.2 m, including 95.58 g/t over 8.0 m (DLD-16-277)
• 21.95 g/t over 9.0 m (DLD-16-278A)

The gold mineralized system (Zone 58N and 75) has been intersected over an east-west strike length of 450 metres, from surface to a depth of 800 metres. The mineralized system remains open at depth.

An independent engineering firm has commenced an initial assessment of the Zone 58N gold mineralization. Geological interpretation of the main mineralized envelope indicates good grade continuity for the upper 250 metres that has been drilled at a 25 metre spacing. The conceptual ore zones were defined by using a minimum stoping width of 3 metres. At this time there is insufficient drilling data at below 250 metres to make a similar detailed interpretation. The surface and underground infrastructure scoping work has started for the development of an underground exploration program. The design, timeline and cost estimate are expected to be completed in the fourth quarter.

"We are highly encouraged with the results of our infill drilling program that are demonstrating good continuity of the zones from surface to 250 metres and indicating amenability to underground mining methods," said Jean-François Metail, Vice President Mineral Resource Management. "While the second part of the drilling program is underway, we will continue with the interpretation and engineering work on Zone 58N. A decision to proceed with the underground exploration program is expected in the fourth quarter."

Metallurgical testing continues to progress in parallel to confirm the amenability of the mineralized material to be processed at the existing Detour Lake plant. At this time, indications are that the mineralized material from Zone 58N is compatible with the current flowsheet.

Gold mineralization is mainly found within an altered feldspar porphyry intrusive characterized by brittle deformation, containing quartz and/or quartz-tourmaline veins with up to 5% pyrite and multiple occurrences of visible gold. The thickness can exceed 100 metres, although individual mineralized lenses are typically up to 30 metres in width. The feldspar porphyry narrows to the east and west.

Regional Exploration Program

In addition, the Company completed 36 holes totaling 9,977 metres on its first pass along the 25 kilometre under-explored Lower Detour trend. Gold mineralization was intersected in several holes giving confidence in the potential of finding high grade mineralization along the trend. Mineralized intercepts included 5.69 g/t over 2.0 metres (DLD-16-247A), 2.65 g/t over 4.0 metres and 1.91 g/t over 3.9 metres (DLD-16-226), and 1.37 g/t over 4.0 metres (DLD-16-236).

The regional drilling program resumed earlier this month with 6,500 metres of drilling in the area east of the current tailings facility where grab and channel samples from several showings returned significant gold mineralization.

Technical Information

The drilling program is being managed by Guy MacGillivray, P.Geo., Exploration Manager of Detour Gold, 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. For this drilling campaign, samples are prepared at ALS Laboratories in Sudbury and assayed at their Vancouver, B.C laboratory. Analysis for gold is done on sawn half core samples (size HQ or NQ) using 50 grams fire assay (AAS finish). Samples with higher grade gold (>3 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.
