December 21, 2022 – Vancouver, BC - Orezone Gold Corporation (TSX: ORE, OTCQX: ORZCF) (the “Company” or “Orezone”) is pleased to provide results from its Phase III resource definition drill program from Maga Hill, Maga Main and Siga zones at its Bomboré Gold Mine in Burkina Faso.
The focus of the Phase III drilling was the conversion of Inferred Resources into Measured & Indicated ahead of the upcoming sulphide expansion study. A key aspect of this infill program at Maga Hill was targeting higher grade granodiorite folded structures which were intercepted in the near surface oxide zones.
Recent drilling continues to return positive results confirming the following:
- Preliminary results at Maga Hill returned several high-grade intercepts within the sulphide zone, with additional results still to come.
- Drilling at the main hanging wall Siga Zone continues to show excellent down-dip continuity.
- Drilling within the Inferred mineralized zones at Siga South and Siga West has been very successful, and preliminary results at Maga Main and Maga Hill are also very promising, with additional results still to come.
- Core drilling has been completed at P8P9 with results expected in the coming weeks.
- RC drilling will also be completed this week which targeted both Inferred and new oxide targets. Results are expected during Q1-2023.
- Modelling of the resources is ongoing as part of the upcoming sulphide expansion study which is expected to be completed in early H2-2023.

Patrick Downey, President and CEO stated, “Ongoing infill drilling continues to return excellent results which confirm very successful targeting of the conversion of Inferred Resources into Measured and Indicated and that this deposit also continues to grow and is still open for further exploration. We have successfully targeted high-grade zones in the sulphides and expanded the known zones significantly both along strike and down dip of existing resources. We are now drilling similar zones at the P8P9 area and expect these results within the coming weeks. This will finalize the drill program for 2022 and modelling will continue to complete the overall conversion of the drilling into the Measured and Indicated categories ahead of the sulphide expansion study which will provide the platform to significantly increase annual throughput and production at the Bomboré operation.
Furthermore, these excellent results targeting the folded zones at Maga Hill and Siga and those from earlier drilling at the P17S zone now warrant further exploration and planning is underway for follow-up drilling in 2023.”

About Orezone Gold Corporation
Orezone Gold Corporation (TSX: ORE OTCQX: ORZCF) is a Canadian mining company operating the open pit Bomboré Gold Mine in Burkina Faso.
Orezone is focusing on mining and processing the Phase I near surface free-dig oxides at a planned annual throughput of 5.2 million tonnes. The Company believes that Bomboré has a significant underlying sulphide resource to support a substantially larger Phase II expansion. A 77,000 m infill and expansion drill program is ongoing and once completed, the Company plans to issue an updated mineral resource and reserve statement and feasibility study, as part of this Phase II expansion. It is expected that the studies will be completed in H2-2023 to be followed by a production decision.
Orezone is led by an experienced team focused on social responsibility and sustainability with a proven track record in project construction and operations, financings, capital markets and M&A.
The technical report for the 2019 Feasibility Study on the Bomboré Project entitled NI 43-101 Technical Report (Amended) Feasibility Study of the Bomboré Gold Project is available on SEDAR under the Company’s profile at www.Sedar.com.

QA/QC
The mineralized intervals are based on a lower cut-off grade of 0.45 g/t, a minimal width of 1.5 m and up to a maximum of 3.0 m of dilution being included. The true width of the mineralization is approximately 90% of the drill length at Siga and 85% of the drill length at Maga. The half-core drilling samples were cut using a diamond saw by Orezone employees. The samples were prepared by SGS Burkina Faso s.a.r.l. (“SGS”) 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 Burkina s.a.r.l. (“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 0.4 g/t 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, with the details available in the tables posted on our web site.
