Orezone Reports 2023 Year-end and Q4 Results, and Provides 2024 Guidance

VANCOUVER, March 26, 2024 - Orezone Gold Corp. (TSX: ORE, OTCQX: ORZCF) ("Orezone" or "Company") reported its operational and financial results for the fourth quarter and full-year ended December 31, 2023. The Company will host a conference call and webcast on March 27, 2024 commencing at 8:00am PDT to discuss its 2023 results and 2024 guidance. Additional details are provided at the end of this press release.

All dollar amounts are in USD unless otherwise stated and abbreviation "M" means million.

Patrick Downey, President and CEO, commented "We had strong end to the year with the production of 33,916 gold ounces in the fourth quarter, allowing us to meet our full year production and cost guidance metrics. In its first full year of commercial production, the Bomboré mine was successful in producing 141,425 gold ounces, which helped the Company generate $80 million in operating cashflow and $54 million in adjusted earnings, and pay down $33.8 million in principal on its senior debt. We expect 2024 to be another profitable year even though guided gold production will be modestly lower than 2023. We continue to advance discussions with our senior lender for the financing of our Phase II hard rock expansion which will pave the way for us to unlock further value from our Bomboré mine. Additional announcements on the Company's financing plans are expected in the second quarter of 2024."

2023 FOURTH QUARTER AND ANNUAL HIGHLIGHTS

¹ Cash costs, AISC, Adjusted EBITDA, Adjusted earnings, Adjusted earnings per share, and Free cash flow are non-IFRS measures. See "Non-IFRS Measures" section below for additional information.

² The Bomboré mine poured first gold on September 10, 2022 and entered into commercial production on December 1, 2022, and produced gold for a partial quarter in Q4-2022 as the mine did not process any significant quantity of ore in October 2022 due to insufficient power as the power plant underwent repairs.

Full Year 2023 Operational Highlights (100% basis unless otherwise noted)

• Safety: The Company continued with its strong safety performance in 2023 with 4.4 million hours worked without a lost-time injury. The Company remains steadfast in promoting worker health through continuous training and safety resources.
• Gold Production: Delivered gold production of 141,425 ounces within the guidance range of 140,000 to 155,000 ounces. Mill throughput was 5.75 million ore tonnes, ahead of nameplate capacity by 10.5%.
• All-in Sustaining Costs: Achieved AISC per ounce sold of $1,127 per ounce which is towards the lower-end of the Company's revised guidance range of $1,100 to $1,180 per ounce.
• Profitability and Adjusted EBITDA: The Company reported net income of $43.1 million and $0.12 per share (basic and diluted) after minority interest. Adjusted EBITDA was $120.0 million, demonstrating the Bomboré mine's strong operating performance in its first full year of commercial production.
• Cash flow: The Company generated cash from operating activities of $104.8 million before working capital changes, and $80.0 million after working capital changes.
• Sustaining capital: Sustaining capital totalled $14.0 million, slightly below the guidance range of $15 to $16 million, as certain capital projects carried over into 2024 for completion.
• Growth Capital:
  • Grid Power: The installation of the 132 kV transmission line, mine substation, and switching station to connect Bomboré to Burkina Faso's national grid was completed in December 2023 and commissioned in January 2024 with input and guidance from SONABEL, Burkina Faso's state-owned electricity company. The line was successfully energized in late January 2024 to commence delivery of lower-cost grid power to site. Construction costs in 2023 totalled $18.2 million.
  • Resettlement Action Plan ("RAP") - Phases II and III: The RAP will help relocate communities occupying areas in the southern half of the Bomboré mining permit. The Company significantly advanced construction of the largest resettlement site (MV3) in 2023 with plans to relocate households into MV3 in Q2-2024 in order to gain mining access to the Siga pits in Q3-2024. During 2023, the Company incurred RAP expenditures totalling $10.4 million.
• Phase II Hard Rock Expansion Feasibility Study: On October 11, 2023, the Company released the results of an updated independent feasibility study for its proposed Phase II expansion ("2023 FS"). The 2023 FS is based on the construction of a 4.4M tonnes per annum ("tpa") hard rock process plant to treat lower transition and fresh rock ore and would operate alongside the existing Phase I oxide plant to significantly increase overall gold production of the Bomboré mine.

Q4-2023 Highlights (100% basis unless otherwise noted)

• Gold production: Gold production of 33,916 ounces, a 10% increase from Q3-2024 gold production, driven by continued strong mill throughput and improved head grades from greater ore release in the pits and lower effect of historical artisanal depletion.
• AISC: AISC per ounce sold was $1,246 per ounce, negatively impacted by higher Burkina Faso royalty rates that came into effect in October 2023.
• Profitability and Adjusted EBITDA: The Company reported net income of $4.0 million and $0.01 per share (basic and diluted) after minority interest. Adjusted EBITDA was $26.7 million.
• Cash flow: The Company generated cash from operating activities of $21.9 million before working capital changes, and $13.9 million after working capital changes.

2023 Corporate Highlights and Subsequent Events

• Consolidated cash of $19.5 million at December 31, 2023, an increase of $10.3 million from December 31, 2022.
• Principal repayment of XOF 20.5 billion ($33.8 million) in 2023 on the Company's senior loans with Coris Bank International ("Coris Bank").
• Two new director appointments: (a) Matthew Quinlan was elected as a new director on June 15, 2023 as an independent nominee of Resource Capital Fund VII L.P., replacing Steve Axcell who did not stand for re-election; and (b) Sean Harvey was appointed as a new member on January 11, 2024 after recently retiring as Chair of Perseus Mining Ltd..
  

2024 GUIDANCE FOR BOMBORÉ MINE

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 600 and CAD/USD of 1.30.
3. Government royalties included in AISC assume an average gold price of $2,000 per oz.
   

Gold production in 2024 is forecasted to range between 110,000 to 125,000 gold ounces with quarterly production expected to be higher in the first and last quarters of the year. Mining will remain confined to the northern zone of the mining permit until better grade oxide ore can be accessed in the southern zone. Staged access to higher-grade southern pits will become available as RAP Phases II and III progresses. The 2024 mine plan anticipates the start of mining in the Siga pits in Q3-2024 after families are relocated to their new homes at the MV3 resettlement site currently under construction. Gold production will decline from 2023 output levels as the prior year benefitted from the processing of higher-grade stockpiles accumulated during the construction phase and the sequencing of higher-grade pits in earlier periods of the mine plan in the northern zone. Restrictions in accessing all areas of the southern zone from the finalization of the ongoing RAP construction will delay the mining of some higher grade pits in this zone from 2024 into 2025.

AISC per ounce sold is estimated to fall within the range of $1,300/oz to $1,375/oz for 2024. AISC per ounce is expected to increase from 2023 due to a combination of lower forecasted head grades and production, higher unit mining costs and strip ratio as mining deepens and more transition material is encountered, and higher royalty rates and assumed gold price, partially offset by lower processing costs as the mine switches to lower-cost grid power as the primary power source in early 2024.

Sustaining capital is expected to range between $14M to $15M with $5M to $6M dedicated towards the tailings storage facility expansion (stage 3 and stage 4 lifts). Other areas of sustaining capital cover mine and mine infrastructure, process plant improvements, security, and camp. Planned expenditures for mining and mine infrastructure is budgeted at over $6.0M and include the purchase of two new RC drill rigs and spares for grade control (replacing more expensive contractor drills), construction of a new explosives magazine (to reduce the frequency of explosives deliveries and associated costs), southern extension of the main haul road, and additional perimeter fencing to restrict public access to new active mining areas.

Growth capital consists of two carryover projects from 2023:

1. Power connection to Burkina Faso's national grid ($1.0M)
   System commissioning of the newly installed transmission line and substations with SONABEL.
   
2. Resettlement Action Plan - Phases II and III ($15M to $16M)
   RAP Phases II and III commenced in 2023 and will see the construction of over 2,200 private and public structures in three new resettlement communities (MV3, MV2, and BV2) to help relocate communities occupying areas in the southern half of the Bomboré mining permit. For 2024, construction costs of $10.0M to $10.5M are forecasted to carry out the completion of MV3 and for the start and expected completion of MV2. RAP costs of $5.0M to $5.5M are estimated for compensation, consultants, relocation allowances, and livelihood restoration programs.

The Phase II Hard Rock Expansion

The Company is the early engineering stage of the Phase II hard rock expansion as contemplated in the 2023 FS. Currently, it is planned that this expansion will be fully financed through operating cashflows and additional senior debt from Coris Bank. Discussions with Coris Bank are ongoing.

The Company intends to provide 2024 guidance for the Phase II hard rock expansion later this year once a binding debt commitment and Board approval have been received.

Liquidity

The Company had cash of $19.5 million and a net working capital deficiency of $30.5 million on December 31, 2023. Significant amounts contributing to the deficiency in working capital include $20.2 million in scheduled monthly repayments on its senior debt, $8.0 million accrual to Genser Energy that is under dispute, and $10.9 million in VAT receivable reclassified from current to non-current due to the timing uncertainty of VAT refunds in Burkina Faso.

The Company is currently negotiating for a bridge loan with Coris Bank to strengthen the Company's cash position as it works towards gaining access to Siga East by Q3-2024 to mine better grade oxide ore. The Company expects loan closing and first drawdown in April 2024.

BOMBORÉ GOLD MINE (100% BASIS) - OPERATING HIGHLIGHTS

¹ Non-IFRS measure. See "Non-IFRS Measures" section for additional details.
² The Bomboré mine poured first gold on September 1, 2022 and entered into commercial production on December 1, 2022, and produced gold for a partial quarter in Q4-2022 as the mine did not process any significant quantity of ore in October 2022 due to insufficient power as the power plant underwent repairs.
³ For a more pertinent overview of the mine's operating performance in the current quarter, Q4-2023 operating results have also been compared against those for Q3-2023.

Bomboré Production Results

Gold production in Q4-2023 was 33,916 ounces, an increase of 52% from the 22,258 ounces produced in Q4-2022. The increase in gold production is attributable to an 80% increase in tonnes processed partially offset by a 12% decrease in head grades and a 3% decline in process recoveries. Higher tonnes processed was due to only a partial quarter of production in Q4-2022 while the lower grades and recoveries are attributable to the processing of high-grade stockpiles accumulated during construction and the non-presence of transition ore in Q4-2022.

Gold production in Q4-2023 increased by 10% from the 30,726 ounces produced in Q3-2023. The increase in gold production is primarily attributable to an 11% increase in head grades from mine sequencing and greater ore release as mining volumes improved by 21% in Q4-2023, benefiting from the deployment of a second mining contractor for the full quarter and the end of the rainy season.

As mining deepens in certain pits, the quantity of transition ore has started to increase. The presence of transition ore results in slightly lower metallurgical recovery and greater consumption of grinding power.

Bomboré Operating Costs

AISC per gold ounce sold in Q4-2023 was $1,246, an increase of 16% from the $1,075 per ounce sold in Q4-2022. The increase in AISC is attributable to higher royalty costs from the new royalty rates that took effect in October 2023 and from a higher realized selling price, and more sustaining capital due to timing.

AISC per gold ounce sold in Q4-2023 decreased by 5% from the $1,306 per ounce sold in Q3-2023. The decrease in AISC is explained primarily by higher gold sales and production as a result of improved head grades.

Cash cost per ore tonne processed in Q4-2023 was $22.00 per tonne, a decrease of 8% from the $23.92 per tonne in Q4-2022. The higher unit cash cost in Q4-2022 was due to processing and G&A costs being absorbed over fewer tonnes as the Bomboré mine had not yet ramped up beyond nameplate capacity until after declaring commercial production on December 1, 2022.

Cash cost per ore tonne processed in Q4-2023 increased by 2% from the $21.57 per tonne in Q3-2023. The higher unit cash cost is attributable to greater reagent consumption to treat more transition ore, higher security spending as the phased deployment of additional security personnel was established for the full quarter, and the recognition of a year-end inventory adjustment partially offset by the benefit of a lower strip ratio and unit mining cost for each ore tonne processed.

Bomboré Growth Capital Projects

Grid Power Connection

The connection of Bomboré to Burkina Faso's national energy grid involved the installation of a 19-km 132kV transmission line, switching station, and mine substation. The construction of these facilities were completed in December 2023 and commissioning of this system began in January 2024 when SONABEL personnel became available after the holiday period. The line was successfully energized in late January 2024 to commence the delivery of low-cost grid power to site. The Company estimates that power generation costs will be reduced by more than 60% or over $3.00/tonne in processing oxide ore when compared to the cost of power generation using on-site diesel gensets.

RAP Phases II and III

RAP Phases II and III involve the construction of three new resettlement communities (MV3, MV2, and BV2) in order to relocate households currently residing within the southern half of the Bomboré mining permit. The Company has sequenced MV3 as the first community to construct in order to gain access to mining areas that are currently contemplated in the 2024 mine plan. MV3 is the largest of the resettlement communities and requires the erection of over 1,200 private homes and public structures.

RAP construction started behind schedule as the construction of MV3 was delayed for two months in 2023 as community members conducted sacred ceremonies for the new resettlement grounds. The Company has engaged several local contractors to construct homes on distinct lots within the MV3 site. In addition, the Company has recruited an owner's team to assist with procurement and construction activities to maintain schedule. The Company is now forecasting completion of the MV3 resettlement site including relocation of households in Q2-2024.
