True North Gold Mine Drilling Summary (FIGURE 1):

710/711:
48 underground holes totaling 23,591 ft (7,190.5 m) were drilled during the reporting period. This definition drilling was targeting both the up-dip and down-dip extensions of the 711 zone and the up-dip extensions of the 710 zone.

These drill results suggest that the mineralization in the 710 and 711 zones continues to extend beyond what has currently been defined.

Cohiba:
12 underground holes totaling 6,122 ft (1,866 m) were drilled during the reporting period. This definition drilling targeted the down-dip extension of the Cohiba zone. These drill results suggest the mineralization in the Cohiba zone continues at depth.

Brian Morris, Vice President Exploration stated, "The results from the 710/711 drilling show that excellent grades and widths continue up-dip as well as down-dip. This is significant as it directs us to continue to drill this structural trend for potential mineral resource addition and to refine our 2017 mine plan." Mr. Morris continued, "Additionally, down-dip drilling on Cohiba is showing very positive results that may support the economics of additional down-dip production at Cohiba."
