OREZONE PROVIDES 2023 PRODUCTION AND COSTS GUIDANCE

All dollar amounts are in US$

January 18, 2023 – Vancouver, BC - Orezone Gold Corporation (TSX: ORE, OTCQX: ORZCF) (the

“Company” or “Orezone”) is pleased to provide 2023 production and costs guidance for its Bomboré Gold

Mine (“Bomboré”) in Burkina Faso. This marks the Company’s first full year as an operating gold producer

after declaring commercial production on December 1, 2022.

For 2023, the Company forecasts gold production in the range of 140,000 to 155,000 ounces at an all -in

sustaining costs1 (“AISC”) of $975 to $1,075 per ounce sold. Capital expenditures are expected to total

between $43 to $49 million as the Company invests in growth projects to improve the future cost structure

and mine life of the Bomboré operation.

Patrick Downey, President and CEO commented, “Our 2023 guidance builds on the strong operating

performance that we saw in December 2022 and includes a number of important initiatives that will

immediately strengthen the long-term value of the mine and position the Company for future growth .

The expected strong cash flow in 2023 will contribute to our debt reduction and growth plans. We intend

on delivering on our annual goals in a safe and responsible manner , while maintaining our strong

community relations as we continue to advance Bomboré towards its next stage of expansion.”

2023 Guidance and Outlook

Operating Guidance (100% Basis) Unit FY2023

Gold Production Au oz 140,000 - 155,000

All-in-Sustaining Costs1, 2, 3 $/oz Au sold $975 - $1,075

Sustaining Capital2 $ million $10 - $11

Growth Capital2 $ million $33 - $38

1. AISC is a non-IFRS measure. Refer to the “Non-IFRS” measures section of this news release for additional

information.

2. Exchange rates used to forecast cost metrics include XOF/USD of 625 and CAD/USD of 1.30.

3. Government royalties included in AISC assumes an average gold price of $1,700 per ounce.

Production Guidance

Gold production is expected to be more weighted towards H1-2023 from better in-pit ore grades due to

mine sequencing and from the reclaim of higher-grade stockpiles as supplemental mill feed.

Plant throughput is forecasted to range between 5.6 to 5.8 million tonnes as milling performance

continues to exceed design since commercial production. Plant recoveries are predicted to remain

consistent with Q4-2022 recoveries of 91.9%

- 2 -

Costs Guidance

AISC per gold ounce sold is expected to be lower in H1-2023 as higher ore grades are processed, partially

offset by greater spending on sustaining capital in the same period.

AISC in 2023 is impacted by the high cost of on-site power generation from rental gensets running on

diesel. The Company is currently in a commercial dispute with Genser Energy (“Genser”) who has failed

to-date on its commitment to supply low-cost LNG power to Bomboré under a power purchase agreement

(“PPA”) signed in June 2021. See “Growth Capital” section below for further details.

Capital Expenditures Guidance

Sustaining Capital

Sustaining capital is forecasted to total between $ 10 to $11 million in the main areas of mine and mine

infrastructure, processing, security, camp, information technology, and safety. The majority of sustaining

capital expenditures is planned for H1-2023.

Sustaining capital includes the finalization of the second lift of the tailings storage facility before the 2023

wet season and minor plant modifications to optimize throughput rates and plant availability.

Sustaining capital includes certain non-recurring costs for camp and infrastructure improvements not

contemplated during construction such as sewage treatment system, water treatment plant, and

recreational facilities.

Growth Capital

Growth capital in 2023 is divided into two main projects:

1. Power connection to Burkina Faso’s national grid ($15 to $18 million)

The Company plans to bring low-cost grid power supplied by SONABEL, Burkina Faso’s state -owned

electricity company, to Bomboré before the end of 202 3 to replace on-site diesel power generation.

Genser previously informed the Company that it will not honour the terms of the PPA which has forced

Orezone to examine alternative power solutions.

Burkina Faso’s national grid was expanded in 2022 to increase the import of clean electricity from

neighbouring countries into Burkina Faso. With this additional capacity, SONABEL can now provide the

reliable power need ed by Bomboré’s current operations as well as those under any future mine

expansion. Based on SONABEL’s rate indications, the Company forecasts a reduction in its future energy

costs by approximately 70%. This forecasted saving equates to approximately $3.10 per oxide tonne

processed assuming current diesel prices in Burkina Faso.

The Company has budgeted for the installation of a 23 -kilometre 132 kV transmission line and mine

substation to deliver grid power to Bomboré with energization of the powerline conservatively scheduled

for by year-end but likely sooner.

2. Resettlement Action Plan (“RAP”) – Phases II and III ($18 to $20 million for 2023)

Phase II and III RAP will see the construction of over 2,200 private and public structures in four new

resettlement villages to help relocate communities occupying areas in the southern half of the Bomboré

mining permit. During 2023, the cost of the RAP is estimated to be $18 to $20 million.

The RAP is scheduled for completion in 2024 but will be significantly advanced in 2023.

Exploration and Evaluation Guidance

Following the extensive and successful 2022 drill program to expand and upgrade inferred resources

ahead of the 2023 expansion study, the Company’s focus in 2023 will be on the release of a new updated

feasibility study on the Phase II expansion of the Bomboré mine (“2023 FS”) which will include a revised

mineral resource and mineral reserve (“MRMR”) estimate, life-of-mine plan, and project economics. The

2023 FS wil l also guide the Company’s decision on the expansion scenario for the sizing and potential

phasing of the future Phase II sulphide plant construction . The Company currently contemplates field

construction of the expansion to commence in H2-2024.

The MRMR estimate will incorporate the results of all drilling completed to the end of 2022 including the

successful step-out drilling undertaken on the P17 trend in 2021 and 2022. The Company anticipates the

release of the 2023 FS results in Q3-2023 accompanied by a NI 43-101 technical report in 45 days.

The Company has budgeted $2.5 million for the preparation of the 2023 FS.

The Company will continue to release the final results from the 2022 drill program throughout Q1-2023.

It also plans to contin ue the reverse circulation (“RC”) drill program in 2023 to target mineralization

outside of known resources and for ad vanced grade control. The program is budgeted for $1.9 million

and includes over 21,000 metres of RC drilling.

Non-IFRS Measures

The Company has included certain terms or performance measures commonly used in the mining industry

that are not defined under International Financial Reporting Standards (“IFRS”), including “all-in sustaining

costs”. Non-IFRS measures do not have any standardized meaning prescribed under IFRS, and therefore

they may not be comparable to similar measures presented by other companies. The Company uses such

measures to provide additional information and they should not be considered in isolation or as a

substitute for measures of performance prepared in accordance with IFRS.

All-In Sustaining Costs (“AISC”) and AISC per ounce sold

This measure is intended to reflect the expenditures required to produce and sell an ounce of gold from

current operations. AISC include mine site operating costs (mining, processing, administration, royalties,

and selling charges), sustaining capital, sustaining mine site exploration, and corporate general and

administration costs . Depreciation and depletion, accretion and amortization of reclamation costs,

growth capital, growth exploration, financing costs, and share-based compensation are excluded from the

Company’s AISC definition. AISC per ounce sold is determined by dividing A ISC by the number of gold

ounces sold.

The Company believes that the use of AISC per gold ounce sold metric will assist investors, analysts, and

other stakeholders of the Company in assessing the operating performance and cash flow generation of

- 4 -

current operations. Upon commencing commercial production and reporting actual AISC, the Company

will provide a reconciliation to IFRS figures then presented.
