Detour Gold Reports on 2016 Exploration Program

TORONTO, ONTARIO--(Marketwired - Jan 30, 2017) - Detour Gold Corp. (TSX:DGC) ("Detour Gold" or the "Company") reports on its 2016 exploration and drilling programs at the Detour Lake property in northeastern Ontario.

2016 Key Highlights

• Positive results from infill drilling program at Zone 58N in the Lower Detour area
• New mineralized system identified in the area of the tailings facility, opening up exploration potential further east

Zone 58N Exploration

In 2016, the Company completed a total of 52,079 metres of infill drilling at Zone 58N, approximately seven kilometres south of the Detour Lake processing plant facility. Since the update provided in July 2016 on the results from the Phase 1 drilling program, the Company received all the assay results from the Phase 2 drilling program completed this fall (15,249 metres in 46 holes). The majority of the infill drilling was at 25 metre spacing, testing the top 250 metres of the deposit. Results continued to demonstrate the continuity of the gold mineralization and provided a high level of confidence in the upper part of the deposit, further confirming the underground mining potential of Zone 58N. Significant assay results from Phase 2 are listed in Table 1.

Zone 58 N - Selected Significant Intercepts from Phase 2 (uncut gold assay reported)

• 14.22 g/t over 13.0 m, including 24.55 g/t over 7.0 m (DLD-16-312)
• 3.16 g/t over 26.0 m and 6.96 g/t over 10.0 m (DLD-16-320)
• 14.21 g/t over 13.0 m (DLD-16-335)
• 12.78 g/t over 7.2 m (DLD-16-340A)
• 28.14 g/t over 9.0 m (DLD-16-346)
• 5.33 g/t over 14.2 m (DLD-16-347)
• 4.19 g/t over 12.0 m (DLD-16-348)

G Mining Services Inc., an independent engineering firm, has now completed a preliminary model and conceptual design for an advanced underground exploration program. The block model assumed a 3 metre minimum horizontal thickness and work is underway to evaluate the potential for wider mining areas. Based on the geological interpretation of the deposit as currently drilled, multiple lenses of potential ore were delineated from bedrock surface to a depth of approximately 800 metres. The deposit remains open below 800 metres.

The conceptual underground advanced exploration program consists of temporary surface infrastructure, a portal and a decline (sized at 5 x 5 metres), cross-cuts and ventilation development necessary to access the deposit for an eventual bulk sample. Diamond drilling would be undertaken from drill bays off the decline to allow for delineation drilling for the upper 400 metres and additional drilling at depth. The estimated cost of this program over a period of five years is expected to range between C$30 and C$50 million. The Company would require an advanced exploration permit to commence this program.

On January 4, 2017, the Company started a surface infill drilling program of approximately 30,000 metres between 250 and 450 metres below surface with the objective of increasing the understanding of grade and geometry for that part of the deposit. Selected holes will also be drilled deeper to delineate continuity at depth.

The gold mineralized system (Zones 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. 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.

TMA Exploration

In the area east of the current tailings facility, approximately 3.5 kilometres east of the Detour Lake open pit, the Company completed 6,195 metres in 19 holes as well as various trenches. Trenching and drilling results have identified shear-hosted gold mineralization over 1,200 metres, opening up exploration potential immediately east of the current tailings facility. Significant assay results from this drilling are listed in Table 2.

For 2017, the Company plans to continue trenching along the current mineralization, extend the geophysical induced polarization (IP) survey, and carry out additional drilling to better understand the controls and orientation of the gold mineralization.

TMA - Selected Significant Intercepts (uncut gold assay reported)

• 3.99 g/t over 4.0 m (DTMA-16-001)
• 9.88 g/t over 1.0 m (DTMA-16-007)
• 4.47 g/t over 5.5 m (DTMA-16-010)
• 5.04 g/t over 1.5 m (DTMA-16-011)
• 5.04 g/t over 1.5 m (DTMA-16-016)
• 12.08 g/t over 11.7 m and 4.06 g/t over 10.9 m (channel samples in Trench 2)
• 4.00 g/t over 5.0 m (channel sample in Trench 6)

The surface plan and cross-sections of Zone 58N, and the surface plan of the drilling and trenching results of the TMA target, are posted on the Detour Gold website: http://www.detourgold.com/projects/detour-lake-exploration-regional/default.aspx

Technical Information

The drilling programs are 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.
