Orezone Intersects 113.74 g/t Gold Over 8.00m in Ongoing Exploration and Provides Project Update






Orezone Gold Corporation (TSX: ORE) (OTCQX: ORZCF) is pleased to provide drill results from its Bomboré Gold Mine located in central Burkina Faso. The results are from Orezone’s ongoing infill and advanced grade control program, which is designed to further delineate multiple high-grade structures within the Siga East and Siga South zones. Mining of higher-grade, free-digging oxides has now commenced at Siga East and mining is scheduled to commence at Siga South in Q4-2024. Compared to the current zones mined, ore from Siga East and Siga South will significantly improve the grades delivered to the process plant in H2-2024 and into 2025.


Selected Drill Intercepts:

  • 113.74 g/t Au over 8.00m from 38.00m in hole BBC6494
  • 1.43 g/t Au over 38.00m from 5.00m in hole BBC6384
  • 1.22 g/t Au over 27.00m from 8.00m in hole BBC6390
  • 1.39 g/t Au over 22.00m from 10.00m in hole BBC6352
  • 1.92 g/t Au over 15.00m from 5.00m in hole BBC6358
  • 2.30 g/t Au over 12.00m from 6.00m in hole BBC6401
  • 1.69 g/t Au over 16.00m from 6.00m in hole BBC6408
  • 4.59 g/t Au over 5.00m from 0.00m in hole BBC6258
  • 1.89 g/t Au over 12.00m from 35.00m in hole BBC6470
  • 2.41 g/t Au over 10.00m from 5.00m in hole BBC6258
  • 1.00 g/t Au over 19.00m from 1.00m in hole BBC6495


Patrick Downey, President and CEO stated, “Ongoing advanced grade control and infill drilling continues to illustrate the continuity of high-grade mineralization within the Siga East and Siga South zones, resulting in some of the highest-grade intercepts reported to-date on the property. These drill results are very encouraging, both in terms of ongoing exploration and the planned shift in mining to increasingly focus on higher-grade, free-digging oxides within the southern portion of the property.


The tighter drill spacing continues to define higher-grade structures within the broader Siga mineralized corridor. These higher-grade structures, now being identified across the property, will be the focus of a multi-year exploration campaign, which is designed to test and delineate higher-grade zones of mineralization at depth. With the current mineral resource down to an average depth of ~200m across 14km of strike, we see significant potential to expand the mineral inventory at depth, while also making additional near-surface discoveries along the emerging, higher-grade P17 trend.”

Operations Update


The Company is pleased to report that the community relocation from Siga East to the new MV3 community is nearing completion, which has allowed mining to commence at Siga East ahead of schedule. The Company expects to feed higher-grade, free-digging oxide ore from Siga East to the Bomboré oxide plant starting in late June. This new source of ore will replace the lower grade oxide and transition ores currently being mined in the north, resulting in lower mining and processing costs as the harder transition ores require a certain amount of drill and blast and have a higher work index than oxide ores.


At Siga South, infill grade control drilling will commence in Q3-2024. Upon completion of this program, combined with the southern extension of the main haul road, the Company expects to access additional high-grade, free-digging oxide ore from Siga South commencing in Q4-2024.


For the remainder of 2024 and in 2025, Siga East and Siga South will contribute to an increasing percentage of the mill feed, which is expected to increase head grades and reduce operating costs



Hard Rock Expansion Update


Orezone is pleased to report that financing discussions for the Bomboré 2.5M tonnes per annum hard rock plant have progressed significantly with our senior lender, Coris Bank. Term sheet negotiations are now in their final stages, and the Company expects to announce a binding debt package before the end of June. The Company plans to commence major works on this brownfield expansion in early July, with first gold from the hard rock plant expected in Q4-2025.

Qualified Person


Dr. Pascal Marquis, Geo., Senior VP Exploration, is the Qualified Person who has approved the scientific and technical information in this news release.




The mineralized intervals are based on a lower cut-off grade of 0.28 gpt in the Oxide+Upper Transition zone, and 0.45 g/t Au in the Lower Transition+Sulfide zone, a minimal width of 1.5m and up to a maximum of 3.0m of dilution being included. The true width of the mineralization is approximately 90% of the drill length at Siga. The reverse circulation samples were prepared by BIGS Global Burkina s.a.r.l. (“BIGS Global”) at their Ouagadougou 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 in Ouagadougou, by bottle-roll cyanidation using a LeachWellTM catalyst. The leach residues from all samples with a leach grade greater than or equal to 0.25 g/t Au were prepared by BIGS Global and then split by Orezone to 50 g using RSDs. A 50-g aliquot was analyzed by fire assay at BIGS Global.


Orezone employs a rigorous Quality Control Program including a minimum of 10% standards, blanks and duplicates. The composite width and grade include the final leach residue assay results for most of the drill intercepts reported.
