Orezone Gold Corporation (“Orezone” or the “Company”) (TSXV:ORE) is pleased to report recent and final Reverse Circulation (“RC”) drilling results from the last two of four specifically identified target areas (See Press Releases of June 22nd 2017 and September 12th 2017) that have been prioritized within the Bomboré deposit to better define the extent and the geometry of discrete zones of high-grade gold mineralization within the oxidized portion of the known gold resources.

The drilling at both P11 and CFU has been successful in intercepting high-grade mineralization in the targeted areas, which should improve grade domaining and resource modeling. More drilling will be required in certain areas to confirm the geometry and continuity of discrete higher-grade zones.

Highlights from P11 and CFU (true width approximately 85% of the drill length):

Patrick Downey President and CEO stated “We set out earlier this year to test four target areas within the existing pit shells that we believed would yield high grade intercepts based on historic results and our new interpretation of the controls for higher grade mineralization. This work has been very successful and we will now proceed to model these zones based on this better quality information. We are confident that once completed this will have a positive impact on the grade of the shallow oxides in these areas and therefore a positive impact on overall grade and project economics within the shallow oxide zone.  We also plan to continue to target higher grade zones to determine if these extend on strike and at depth within the sulphide mineralization.”

The RC drilling programme commenced on July 8, 2017 and was designed as essentially infill holes to tighten up the drill spacing from 50 m by 25 m to 25 m by 25 m in the four specific target areas. Some 249 drill holes totalling 13,900 m have been completed on the Siga South, Siga East, P11 and CFU targets by October 18, 2017 when the program was suspended. Similar infill drilling targeting discrete high-grade oxide mineralization is planned in 2018 where more drilling should better confirm the geometry of the high-grade zones. All drill holes in the Siga South and Siga East areas were oriented at the collar N250[1] with a plunge of -50 degrees. All drill holes in the P11 area were oriented at the collar N270 with a plunge of -50 degrees. All drill holes in the CFU area were oriented at the collar N312 with a plunge of -50 degrees.

The mineralized intervals are based on a lower cut-off grade of 0.45 g/t, a minimal width of 2 m and up to a maximum of 1.5 m of dilution being included. The true width of the mineralization is approximately 90% of the drill length at Siga South and Siga East, and 85% of the drill length at P11 and CFU. 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 Rotary Sample Dividers (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 LeachWellTM catalyst. The leach residues from all samples with a leach grade in excess of 0.2 g/t were prepared by BIGS Global Burkina s.a.r.l. and then split by Orezone to 50 g using Rotary Sample Dividers (RSDs). A 50-g aliquot was analyzed by fire assay at SGS Burkina Faso s.a.r.l. SGS Burkina Faso s.a.r.l is independent of Orezone. The composite width and grade include the final leach residue assay results for most of the drill intercepts reported; some leach residue assays are pending for 5 RC holes. Orezone employs a rigorous Quality Control Program (QCP) including a minimum of 10% standards, blanks and duplicates.
