Detour Gold’s strategy is to create additional shareholder value through organic growth. The Company has consolidated the Detour Lake area and now controls approximately 625 km2. The Company also controls the Burntbush Property, totaling 494 km2 strategically located on the Ontario side of the Casa Berardi fault.

Detour Lake Property (625 km2

Lower Detour Area - Zone 58N

The Company continues to explore its large prospective land holdings with a focus on the Lower Detour Deformation Zone (“LDDZ”), a major structural break, that is parallel and less than 7 kilometres south of Sunday Lake Deformation Zone (“SLDZ”), which hosts the Detour Lake deposit. The LDDZ has been traced over an approximate strike length of 25 kilometres on the property and remains largely underexplored.

The Company has conducted small exploration programs along the LDDZ, completing a total of 70,349 metres of drilling in 169 holes from 2013 to 2015 which have defined three sub-parallel mineralized structures: Zones 75, 58 and 58N. The high grade Zone 58N is the current focus of the Company's explorations activities. In 2016, the Company completed 52,079 metres of infill drilling in 168 holes with the majority of the drilling at a 25 metre drill spacing above 250 metres. This mineralized system has been intersected over an east-west strike length of 450 metres, from surface to a depth of 800 metres, and the mineralized system remains open at depth.

The 2017 winter drilling program at Zone 58N was completed with approximately 21,805 metres in 58 holes.  The drilling program focused between vertical depths of 250 and 450 metres at a 35 metre spacing.  Assay results are expected prior to end of the second quarter and will be incorporated in the model and conceptual design in preparation for an advanced underground exploration program.

The drilling program is expected to continue this summer at Zone 58N.

Regional Exploration

In 2016, 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).

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. See surface plan below. 

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.

Burntbush Property (494 km2

The Company controls two groups of contiguous claims totaling 494 km2 comprising its new Burntbush project in the District of Cochrane in northeastern Ontario, approximately 115 kilometres northeast of the Town of Cochrane and 70 kilometres south of its flagship Detour Lake mine.

The Burntbush East and West properties are strategically located along the Casa Berardi deformation zone in the Abitibi Greenstone Belt, approximately 35 and 75 kilometres respectively, west of the Casa Berardi gold mine operated by Hecla Mining Company, which has produced approximately 1.9 million ounces of gold since it commenced production in 1988.

In general, exploration on the Ontario side of the Casa Berardi fault has been minimal due to limited access, overburden and the lack of outcrop exposures. Historical and more recent exploration activities have focused on the main structural break. The Burntbush grassroot properties cover more than 80 kilometres of primary (EW) and secondary (NE-SW) subsidiary faults. It also encompasses a number of gold anomalies intersected in old diamond drill holes, including an intercept of 6.41 g/t over 2.9 metres drilled by Newmont in 1985, and in till samples from a 2005 regional program by the Ontario Geological Survey. Immediately east of the West claim group, drilling by Lakeshore Gold in the mid-2000s delineated a 500 metres gold mineralized horizon (Porphyry Creek Zone). Within the East claim group, in the portion not controlled by Detour Gold, a small NI 43-101 compliant gold resource (A8 3200 Vein System) was reported in 2013 by Alpha Minerals.

A 2017 exploration program currently in preparation will include high resolution airborne magnetic and electromagnetic surveys, along with field mapping and prospecting.
