Higher Grade Zone at Bomboré Expands Along Newly Identified Mineralized Trend

Highlights include 12 m at 3.4 gpt and 9.6 m at 3.8 gpt
Recent drill results suggests potential for a 3 km prospective corridor

Orezone Gold Corporation ("Orezone" or the "Company") (TSXV: ORE) is pleased to announce further positive results from an ongoing drill program at its Bomboré Gold Project in Burkina Faso. The program is currently focused on expanding the P17S sulphide zone situated 2 km south of the Bomboré mining permit, and exploring for similar granodiorite-hosted gold mineralization on the property.

Drilling to date has now intersected the P17S mineralized granodiorite from surface to a vertical depth of 150 m with a down-plunge continuity exceeding 425 m. Highlights include:

Hole TYD0073, which returned 4.80 m of 2.29 g/t Au and 6.30 m of 4.47 g/t Au;
Hole TYD0074, which returned 8.50 m of 3.95 g/t Au;
Hole TYD0075, which returned 9.60 m of 3.80 g/t Au;
Hole TYD0076, which returned 12.00 m of 3.40 g/t Au;
Hole TYD0077, which returned 14.00 m of 1.65 g/t Au;
Hole TYD0078, which returned 5.00 m of 4.94 g/t Au;
Hole TYD0079, which returned 5.90 m of 2.44 g/t Au;
Hole TYD0080, which returned 5.00 m of 3.17 g/t Au;
Hole TYD0081, which returned 8.80 m of 2.70 g/t Au;
Hole TYD0082, which returned 13.30 m of 2.06 g/t Au;
Hole TYD0083, which returned 9.70 m of 3.38 g/t Au;
Hole TYD0084, which returned 2.00 m of 14.10 g/t Au; and
Hole TYD0087, which returned 6.90 m of 4.85 g/t Au.

Significantly mineralized granodiorite has now been intercepted to the northeast of P17S in a series of scout drilling holes that were targeting the gap between the P17S and P17 deposits where the prospective sequence has now been confirmed over an additional strike length of more than 400 m.  Highlights include:

Hole BBD0978, which returned 9.00 m of 1.49 g/t Au;
Hole BBD0980, which returned 10.00 m of 3.20 g/t Au;
Hole BBD0981, which returned 8.20 m of 1.89 g/t Au and 7.80 m of 1.54 g/t Au;
Hole BBD0982, which returned 9.80 m of 1.55 g/t Au; and
Hole TYD0077, which returned 14.00 m of 1.65 g/t Au.

Furthermore, at Zone 172, less than one kilometer to the southwest of P17S, scout RC drilling of auger drilled gold anomalies and limited core drilling intersected mineralized granodiorite within a meta-gabbro sequence. All three zones, (172, P17S and P17) span a corridor of more than 2.5 kilometers in length and about 400 m in width that is now interpreted to be very prospective for the higher-grade granodiorite-hosted gold mineralization.  See Figures 1 and 2 below.

Commenting on the results, Patrick Downey, President and CEO, stated, "These new drill results along the P17 corridor continue to demonstrate the potential to both expand higher grade shallow resources at Bomboré and open up previously untested zones.  The drilling continues both to intercept mineralization containing both good grade and widths and is open along strike and down dip.  The Company plans to continue drilling in this prospective corridor and to evaluate and drill other prospective areas on this largely underexplored property."

The Company has completed more than 13,000 m of auger, reverse circulation and core drilling to date in 2017 and is planning additional drilling before the 2017 rainy season.

All assays were performed using a 1kg bottle roll technique (identical to the other Bomboré samples); leach residue assays are pending for 3 core holes.  A complete list of historical drill results on P17S and analytical procedures can be found on the Company’s website at the following link (P17S Drill Results). Please note true widths to be determined.
