Roxgold continues to extend the 55 Zone at depth with high grade mineralization

TORONTO, Nov. 1, 2017

Highlights:

• 44.0 grams per tonne ("gpt") gold over 3.0 metres ("m") within a broader interval of 11.2 gpt gold over 12.5 m and a separate interval of 12.9 gpt gold over 3.9 m including 47.8 gpt gold over 1.0 m in diamond drill hole YRM-17-DD-443BW1 at the 55 Zone
• 8.4 gpt gold over 5.1 m including 21.0 gpt gold over 1.4 m in diamond drill hole YRM-17-DD-440 at the 55 Zone
• Large geophysical program recently completed with drilling on multiple targets underway
• Infill and Extensional drilling program in progress at Bagassi South
• Currently three drill rigs active at Bagassi South and on regional targets

"The second phase of deep drilling at the 55 Zone was designed to follow-up on the late 2016 program which included hole YRM-16-DD-426, the widest mineralized zone ever intersected on this project, which returned 20.1 grams per tonne of gold over 23.8 metres," stated John Dorward, President and CEO of Roxgold. "Multiple zones of high grade mineralised quartz veins were intersected within a wide zone in hole YRM-17-DD-443B-W1 in the 2017 program, a target drilled down plunge from hole YRM-16-DD-426 at a vertical depth of approximately 1,100 metres."

55 Zone Drilling

The 2017 deep drilling program at the 55 Zone has extended the success of the 2016 deep drilling program at the 55 Zone. The two primary goals of the program were to drill test the 55 Zone extension down plunge from drill hole YRM-16-DD-426 (20.1 gpt over 23.8 m), below the current inferred resource boundary and to test the western portion of the mineralized shoot at depth, west of drill holes YRM-12-DD-242 (22.7 gpt over 4.1 m) and YRM-12-DD-250 (24.3 gpt over 4.4 m).

Results from this program continue to confirm the continuity of the 55 Zone below the current resource with all eight holes of the 2017 deep drilling program intersecting the shear structure. Drill hole YRM-17-DD-443BW1 intersected two zones of high grade mineralization at a vertical depth of approximately 1,100 metres below surface, one of the deepest drill holes to ever intersect the 55 Zone structure. The first interval was intersected at a drill depth of 1,329.5 metres, a 12.5 metre zone of high grade mineralization returning 11.2 gpt over that interval including 44.0 g/t over a 3.0 metre interval while the second interval intersected 12.9 gpt over a 3.9 metre width, including 1.0 metre at 47.8 gpt.

Drill hole YRM-17-DD-443BW1 was drilled deeper and to the east of drill hole YRM-16-DD-426, approximately 175 metres down plunge, extending the high-grade shoot to a vertical depth of approximately 1,100 metres below surface and over 800 metres below the current position of the underground ramp.
