News

Orezone Gold Corporation (TSXV:ORE) (“Orezone” or the “Company”) is pleased to report recent Reverse Circulation (“RC”) and Diamond Drilling (“DD”) drilling results from several target areas that lie outside of the main Bomboré deposit mining permit. This programme totalled 55 RC boreholes (2,904 m) and 34 DD boreholes (4,916.5 m) that were drilled during Q1 2018. These new results continue to show significant potential to expand both oxide resources and near surface high-grade sulphide resources within the current Bomboré land package.

Orezone has also completed 12,171 m of RC oxide drilling and 3,766 m of oxide and sulfide core drilling within the mining permit during Q2 2018, and will report these results once all assays are received.

P17S Sulphide Target Expansion

A general location map, and plan and section for P17S are shown in the attached link (link).

The core drill results from the P17S target are a follow-up to previous drilling (see February 22, 2018 press release), which has defined several continuous shallow plunging mineralized zones that extend from surface to a depth of at least 215 m. These mineralized zones are associated with thickened fold hinges plunging northwards with a down-plunge extent of at least 500 m for the Main P17S zone outcrop, along a folded granodiorite unit, oriented NNE between the P17S and P17 deposits. The total strike extent is currently 1.8 km, including a 500-m gap that has yet to be drill tested. These new results continue to better define the extent and the geometry of the higher-grade P17S gold zones located approximately 2 km south of the Bomboré mining permit. Previous metallurgical test results have shown that the P17S sulphide material is free milling with excellent gold recoveries above 90%. The current release includes final results from the 23-core hole (4,017 m) follow-up programme completed at P17S during Q1 2018.

Highlights from P17S main zone down-dip and down-plunge extension include (true width about 80% of drill intercept length):

Prospect KT

This near surface oxide target area is located within 1.5 km to the north of the Bomboré mining permit. The recent RC drill program is a follow-up to historical scout drilling by auger, RAB and RC (with high-grade hits) outside of the current Bomboré qualified resource but in a similar geological environment. The current release includes final results from the 23-RC hole (1,070 m) and 3-core hole (237.5 m) programme completed at KT during Q1 2018. This programme has been successful in determining that the oxide mineralization remains open outside of defined resources, and these new results are consistent with a shallow to moderate northeast plunge for the discrete higher-grade mineralized zones at KT.

Prospect P13

This near surface oxide target area is located within 6 km to the southwest of the Bomboré mining permit. The recent RC drill program is a follow-up to historical scout drilling by auger and RC (with high-grade results) outside of the current Bomboré qualified resource but in a similar geological environment. The current release includes final results from the 25-RC hole (1,447 m) and 6-core hole (510 m) programme completed at P13 during Q1 2018. This programme has been successful in determining that oxide mineralization is present along a potential strike length of some 3 km at P13.

• TYC0200: from 3 to 8 m: 5 m @ 0.94 gpt.

 Patrick Downey, President and CEO stated, “We are extremely pleased with these most recent drilling results as we continue to advance Bomboré towards production. The ongoing results from P17S continue to show good grade, thickness and continuity of the several limbs of this folded granodiorite which remains open to both the NNE and SSW with excellent potential to add higher grade free milling sulphide resources in this area and to explore for additional similar targets.

The Company plans to complete a Preliminary Economic Assessment (“PEA’) on this zone once a resource update is completed to determine if adding a small 1,000 to 2,000 tonnes per day crushing circuit to feed this higher-grade sulphide material ahead of the ball mill could add to the production profile of the project in the recently released feasibility study results (see July 9, 2018 press release).

Results from targets KT and P13 show that the oxide resources also remain open to expansion and add to the exploration potential of the overall Bomboré project.”

Sampling, analytical and QAQC protocols

The mineralized intervals are based on a lower cut-off grade of 0.45 gpt, a minimal width of 2 m and up to a maximum of 2 m of dilution being included. The true width of the mineralization is approximately 80% of the drill length at P17S and are yet to be determined at targets KT and P13. The RC drilling samples were divided by Orezone employees using Rotary Sample Dividers (“RSDs”). A 2-kg split was prepared by SGS Burkina Faso s.a.r.l. at the Bomboré sample preparation facility and then split by Orezone to 1 kg using RSDs. A 1-kg aliquot was analyzed for leachable gold at BIGS Global Burkina s.a.r.l in Ouagadougou, by bottle-roll cyanidation using a LeachWell^TM catalyst. The leach residues from all samples with a leach grade in excess of 0.2 gpt were prepared by BIGS Global Burkina s.a.r.l. and then split by Orezone to 50 g using RSDs. A 50-g aliquot was analyzed by fire assay at SGS Burkina Faso s.a.r.l. The composite width and grade include the final leach residue assay results for all of the drill intercepts reported. Orezone employs a rigorous Quality Control Program (QCP) including a minimum of 10% standards, blanks and duplicates. A complete list of assay results from the current drilling programme can be found on the Company’s website at the following link (Drill Results).
