Orezone Reports Fourth Quarter and Full Year 2022 Results

March 23, 2023 – Vancouver, BC - Orezone Gold Corporation (TSX: ORE, OTCQX: ORZCF) (“Orezone” or

“Company”) today reported its financial and operating results for the fourth quarter and full year 2022.

(All dollar amounts in USD unless otherwise indicated. “M” denotes million.)

Fourth Quarter and Full Year 2022 Highlights

• Gold production of 22,258 ounces in Q4-2022 and 27,831 ounces for 2022.

• Gold sales of 24,676 ounces for both Q4 -2022 and 2022, at an All -In Sustaining Costs ("AISC")1 per

gold ounce sold of $1,075 and revenue of $43.4M.

• Net income attributable to shareholders of Orezone of $3.8M for Q4-2022 and $0.9M for 2022.

• Cashflow from operations of $28.5M for Q4-2022 and $6.0M for 2022.

• Cash balance of $9.2M at December 31, 2022, an increase of $1.8M from September 30, 2022.

• Achievement of 2022 guidance including:

 Pouring of first gold on September 10, 2022.

 Declaration of commercial production at Bomboré on December 1, 2022.

 Delivery of the Bomboré project construction (excluding the third -party managed power plant)

on schedule and under budget. Final project construction costs including pre-production mining

but excluding power plant totalled $168.9M, below the project approved budget of $173.8M.

 Orderly transition from construction and commissioning to operations as the Company benefitted

from operational readiness activities undertaken prior to first gold.

 Completion of its Phase III exploration drill campaign with the purpose of extending Bombo ré

sulphide expansion potential by converting sulphide resources from Inferred to the Measured and

Indicated categories. The Phase III campaign successfully returned numerous wide, high -grade

intercepts in mineralized zones within Maga, Siga, P8P9, and th e P17 trend. The Company will

incorporate these new and encouraging drill results into a revised mineral resource and mineral

reserve estimate that is being prepared as part of the planned 2023 feasibility study update for

the Phase II Sulphide Expansion.

Patrick Downey, President and CEO, stated “2022 was a milestone year culminating in the declaration of

commercial production before year-end. In a span of under two years, we have succeeded in meeting the

challenges of financing and building a greenfield mining project to deliver a profitable mine on time and

under budget. The Bomboré process plant is now operating above expectations after initial difficulties

with reliable power were resolved. Bomboré continues to generate strong operating cashflows that we

are directing towards working capital, debt repayments, and growth projects including installation of grid

power which will significantly reduce processing costs once installed.

We see 2023 as another exciting year as we work on the release of an updated feasibility study for our

Phase II Sulphide Expansion. The study will incorporate over 100,000 metres of drill results including those

from the Phase III drill program completed in 2022 . A larger Phase II Sulphide Expansion than that

contemplated in the current 2019 study is now envisioned and we look forward to sharing the details of

this new study later this year.”

1 The Bomboré Mine entered into commercial production on December 1, 2022. Unit cash costs during pre-commercial production are

not representative of cost performance expected under steady -state operations. Cost figures presented for Q4- 2022 and FY2022

include a blend of costs before and during commercial production.

2 The Bombore Mine did not process any significant quantity of ore for the month of October 2022 due to insufficient power as t he

power plant underwent repairs. As a result, departmental costs for processing and site general & admin have been excluded from

the cash cost and AISC figures presented for Q4-2022 and FY2022. These costs have been capitalized as commissioning costs.

3 Non-IFRS measure. See “Non-IFRS Measures” section for additional details.

Commissioning of the process plant with ore commenced in late August 2022, resulting in the pouring of

first gold on September 10, 2022. Ore commissioning was delayed by approximately four weeks as the

third-party managed power plant encountered numerous commissioning difficulties and was unable to

provide sufficient power for mill operations. During September 2022, the process plant did commence

operations but the on -site gensets fell significantly short of t heir rated power output, restricting mill

throughput to a reduced level. In late September 2022, one of the two working permanent gensets

experienced a major failure. As a consequence, mill operations were stopped in October 2022 and

recommenced in November 2022 with the use of temporary rental gensets. With full and reliable power,

the process plant quickly ramped -up daily mill tonnages leading to the achievement of commercial

production on December 1, 2022.

The process plant continued with its impro ved performance in December 2022 with mill throughput

exceeding nameplate design by 4% and process recoveries reaching design levels. Strong operations at

the Bomboré process plant have carried on into 2023 with mill throughput at 12% above nameplate for

the first two months of 2023.

2023 Outlook

The Company expects to continue the strong operating performance at the Bomboré mine into 2023,

building upon the solid monthly production results attained in December 2022. The Company intends to

- 4 -

utilize operating cashflow generated by Bomboré to reduce its senior loans with Coris Bank and to fund

growth initiatives that will improve the future cost structure and mine life of the Bomboré operation.

1. AISC is a non-IFRS measure. See “Non-IFRS Measures” section below for additional information.

2. Foreign 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 oz.

Revision to Original 2023 Guidance (refer to Company’s press release of January 18, 2023)

Sustaining capital has been revised upwards by $5M to $15M - $16M from the Company’s original

guidance of $10M - $11M. The Company has decided to redirect nearby waste generated during the 2023

mine plan to continue with the stage 3 lift of the tailing storage facility (“TSF”). The previous guidance

contemplated the commencement of this stage 3 lift in 2024 using waste with a longer -haul profile and

additional re-handle. The acceleration of this construction activity will ensure sufficient available tailings

storage ahead of the sulphide expansion and will result in lower overall costs for the TSF expansion as it

eliminates waste re -handle costs. Once completed, the stage 3 lift is expected to provide TSF storage

capacity to capture tailings from production to mid-2025.

Correspondingly, 2023 guidance for AISC per gold ounce sold has also been revised upwards by $35/ounce

to $1,010/ounce - $1,110/ounce.

2023 Guidance Details

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 5.6M to 5.8M tonnes with plant recoveries approximating

91%.

AISC per gold ounce sold is expected to be lower in the H1-2023 in step with the higher planned gold

production for this period. Overall, AISC in 2023 will be impacted by the high cost of diesel- generated

power from on-site rental gensets until the Company’s connection to the national grid is energized.

Sustaining capital will range between $15M - $16M with $9M dedicated towards the TSF lifts (stages 2

and 3). Other areas of sustaining capital include mine and mine infrastructure, processing, security, camp,

information technology and safety. Capital coverin g camp and infrastructure improvements are

considered one-time projects not contemplated during the main construction such as site -wide sewage

treatment system, potable water treatment plant, and recreational facilities.

Growth capital consists of two main projects:

(i) Power connection to Burkina Faso’s national grid ($15M - $18M)

- 5 -

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

owned electricity company, to Bomboré before the end of 2023 to replace the high-cost, on-site

diesel power generation. The Company has budgeted for the installation of a 23 -km 132 kV

transmission line, mine substation, and switching station needed to connect Bomboré to Burkina

Faso’s national grid. Energization of the powerline is scheduled for Q4-2023

(ii) Resettlement Action Plan (“RAP”) – Phases II and III ($18M - $20M for 2023)

RAP Phases II and III 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, RAP costs are estimated to be $18M - $20M. The RAP

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

Exploration and evaluation spending includes $2.5M for the preparation of an updated Phase II Sulphide

Expansion feasibility study and $1.9M for the continuation of a reverse circulation (“RC”) drill program to

target mineralization outside of known resources and for advanced grade control. This drill program

covers 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 is not defined under 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 gold ounce sold

The 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 exploration, and corporate general and administration

costs. E xcluded from the Compa ny’s AISC definition are d epreciation and depletion, accretion and

amortization of reclamation costs, growth capital, growth exploration, financing costs, and share -based

compensation. AISC per gold ounce sold is determined by dividing AISC by the number of gold ounces

sold.

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

stakeholders of the Company in assessing the operating performance and cashflow generation of current

operations.

Growth capital (including capitalized borrowing costs) 9,835 130,890

Sustaining capital 1,550 1,550

The distinction of sustaining capital from growth (non -sustaining) capital follows the guidance set forth

by the World Gold Council which defines non -sustaining capital as costs incurred at new operations and

costs related to major projects at existing operati ons where these projects will materially benefit the

operation. A material benefit to an existing operation is considered to be at least 10% increase in annual

or life-of-mine production, net present value, or reserves compared to the remaining life of mine of the

operation.

For 2022, predominantly all capital expenditures are considered non -sustaining as they relate to the

construction, pre -production mining, and commissioning of the Bomboré mine. Sustaining capital

primarily relates to the stage 2 lift of the TSF expansion.

Sustaining Exploration Expense

($000s) Q4-2022 FY2022

Exploration and evaluation costs 3,065 7,932

Non-sustaining exploration and evaluation costs 3,065 7,932

Sustaining exploration expense nil nil

For 2022, exploration and evaluation costs were dedicated to exploratory drill programs to add new

Inferred resources and to upgrade existing Inferred mineral resources into Measured and Indicated, and

to study costs towards an updated Phase II Sulphide Expansion feasibility study to be released in 2023.
