Orezone Provides 2026 Guidance for Casa Berardi

July 7, 2026 – Vancouver, BC - Orezone Gold Corporation (TSX: ORE, ASX: ORE, OTCQX: ORZCF) (the

“Company” or “Orezone”) is pleased to provide its production and cost guidance for its recently acquired

Casa Berardi gold mine . The guidance reflects the Company's 2026 operating plan s for the mine

subsequent to its acquisition on March 25, 2026.

Patrick Downey, President and CEO, commented: "Since taking ownership, our focus at Casa Berardi has

been on int egrating the operation, gaining a deeper understanding of the asset and identifying

opportunities to enhance its future performance. Ongoing work since the acquisition has reinforced our

view that Casa Berardi is a long -life asset in a Tier -1 jurisdiction . Its substantial mineral endowment,

extensive existing infrastructure and significant exploration upside provide a strong platform for long-term

value creation.

2026 will be a transition year for the operation a s we continue to mine readily accessible lower-grade

underground ore while completing additional waste stripping in the F160 pit to improve access to higher

grades in the pit bottom and prepare for future pit cut-backs to extend the pit life. These investments will

result in higher average AISC for the remainder of 2026 . Over the longer-term, we expect unit costs and

AISC to trend lower , as improved grades and productivity are realized through accelerated underground

development, new mining equipment and a significantly expanded definition drilling program.

Our clear focus is on strengthening Casa Berardi for future growth through ongoing investments and we

look forward to issuing a new life-of-mine plan in September, which will further outline our long -term

strategy of optimizing operations and realizing the full potential of the mine."

Casa Berardi 2026 Guidance

The following guidance covers the post-acquisition period from March 25 to December 31, 2026:

Casa Berardi Unit 2026 Guidance1

Gold production1 Au oz 62,000 - 67,000

All-In Sustaining Costs1,2,3 US$/oz Au sold $2,600 - $2,800

Sustaining capital1,2,3 US$ million $37 - $39

Growth capital1,2,3 US$ million $5 - $6

1. Period from March 25, 2026 to December 31, 2026

2. Non-IFRS measure. See “Non-IFRS Measures” section below for additional information

3. Guided cost metrics assume a CAD/USD foreign exchange rate of 1.35

Gold Production

Quarterly gold production is expected to be lowest in the third quarter as mining at the F160 pit is

concentrated on waste stripping resulting in the feeding of lower-grade stockpiles. Production is expected

to strengthen in the fourth quarter as more higher-grade open pit ore is delivered to the mill.

All-in Sustaining Costs

All-In Sustaining Cost (“AISC”) is guided to fall between US $2,600 – US$2,800/oz. The accounting

standards followed by the Company for the acquisition of Casa Berardi require that gold inventories and

ore stockpiles be increased to their estimated closing date fair values. The sale of the gold inventory and

the processing of ore stockpiles in subsequent periods will impact cost of sales and therefore, AISC

otherwise reported. The Company has chosen to exclude these non -recurring, non -cash accounting

adjustments from AISC as they are not representative of the operating performance of the mine

Capital Expenditures

Sustaining capital is estimated at US$37 – US$39 million with spending directed toward accelerated

underground development, the purchase of new underground mobile mining equipment, tailings lift, and

process plant improvements. Growth capital estimated at US$5 – US$6 million is primarily for engineering,

technical studies and permitting in support of future mine development.

Exploration

Fifty-eight thousand metres of diamond drilling is planned targeting three key objectives: converting

Inferred Mineral Resources to Indicated Resources through infill drilling, expanding existing underground

ore zones down plunge , and testing new near -mine exploration targets. The progr am is designed to

support both near -term mine planning through resource conversion and long -term growth through

expansion and near -mine exploration. The Company has five exploration drill rigs operating on site and

intends to increase exploration activities toward a sustained annual drilling rate of 80,000 to 100,000

metres.

Updated Life-of-Mine Plan

Orezone expects to publish an updated life -of-mine plan for Casa Berardi in September 2026, outlining

the Company's long-term operating strategy, mine development plans and exploration opportunities.
