OREZONE INTERCEPTS FURTHER HIGH-GRADE MINERALIZATION BELOW LIFE OF MINE PITS INCLUDING 1.59 G/T GOLD OVER 48.00M AND 1.09 G/T GOLD OVER 45.00M

Orezone Gold Corp. has provided additional drill results from its continuing multiyear exploration campaign at its flagship Bombore gold mine. The latest results are from the North and P8P9 zones, targeting the down plunge continuity of higher-grade subzones beneath the current life of mine pits.

Selected drill highlights:

• 1.59 grams per tonne Au over 48.00 metres, including 4.86 g/t Au over 9.00 m (BBD1358);
• 1.09 g/t Au over 45.00 m, including 2.56 g/t Au over 8.00 m (BBD1370), within a broader mineralized intercept of 0.64 g/t Au over 157.00 m;
• 1.97 g/t Au over 16.10 m, including 2.74 g/t Au over 10.10 m (BPC7217);
• 2.01 g/t Au over 14.00 m (BPC7216);
• 2.67 g/t Au over 7.40 m (BBD1367);
• 1.63 g/t Au over 11.00 m (BPC7216);
• 1.48 g/t Au over 8.75 m (BBD1369);
• 1.82 g/t Au over 6.40 m (BPC7210);
• 1.16 g/t Au over 9.00 m (BBD1369);
• 1.47 g/t Au over 6.50 m (BBD1368);
• 1.01 g/t Au over 9.00 m (BPC7217).

Patrick Downey, president and chief executive officer, stated: "These latest drill results confirm the down plunge continuity of multiple higher-grade subzones, with mineralized traces extending beneath the current resource pits and remaining open at depth. The targeted drilling at the north and P8P9 zones further underscores the near-term potential at Bombore to selectively pull higher-grade reserve pits to depth across the greater 14 km long reserve defined trend. Of particular significance is the very broad subzone of mineralization at depth in P8P9. This zone does not appear at surface and is the broadest zone of continuous mineralization that has been intercepted at Bombore, demonstrating significant exploration potential.

"The results of this concentrated drilling serve to complement the ongoing wider spaced stepout drill program, which is focused on identifying new higher-grade centres of mineralization both at depth and near-surface along strike.

"In H1 2025, approximately 30,000 m of exploration drilling was completed at Bombore. The company is extremely pleased with the results and success of the program to date, which includes 1) extending North zone footwall mineralization up to 200 m below the current reserve pits along an 800 m strike length (including 2.55 g/t Au over 23.00 m and 1.14 g/t Au over 29.50 m); 2) extending mineralization of the P17S high-grade subzone a further 300 m down plunge (7.40 g/t Au over 6.70 m); and 3) identifying multiple broad near-surface strike extensions (including 2.22 g/t Au over 14.00 m, 1.12 g/t Au over 10.00 m and 0.92 g/t Au over 14.35 m).

"Drilling will continue in H2 2025 on multiple fronts in support of the company's long-term goal of increasing Bombore's current stated global resource from five million ounces to a targeted seven million to 10 million ounces longer term. This is truly an exciting prospect with the continuing hard rock expansions positioned to increase Bombore's overall production to 220,000 to 250,000 ounces per annum."

North and North Hill zone

The continuing drilling program continues to define and expand mineralized trends along the three-kilometre strike length of the North zone. Mineralization in the shear-hosted Footwall zone is associated with rheological and chemical differences between siltstones and shales and the volcaniclastic footwall sediments. Gold grades are correlated with quartz veinlets with disseminated pyrite and arsenopyrite as accessory minerals. Ore shoots are developed where north-northeast-trending steep-dipping shears intersect the northeast-trending and easterly dipping footwall shear. Fold hinge and stretching lineation measurements confirm the moderate north to north-northeast-plunging mineralization.

The North Hill zone, which sits east of the Footwall zone, continues to deliver promising grades and widths with higher grades corresponding to increased extensional quartz veining. These veins occur between two steep-dipping north-northeast-trending mineralized deformation zones suggesting continuing deformation has resulted in sites of dilation orthogonal to the steeper shears.

The recent drilling was successful in confirming 1) the down plunge continuity of the higher-grade North Hill subzone beneath the life of mine reserve pit (including intercepts of 1.59 g/t Au over 48.00 m and 1.97 g/t Au over 16.10 m); and 2) further delineating higher-grade mineralization within the west dipping footwall shear (2.01 g/t Au over 14.00 m). Both of these higher-grade trends remain open to depth, and will be the focus of future follow-up drilling.

• 5.35 g/t Au over 21.00 m (BBD1220);
• 3.14 g/t Au over 18.00 m (BBD1285);
• 3.30 g/t Au over 20.00 m (BBD1219);
• 2.55 g/t Au over 23.00 m (BBD1324).

P8P9 zone

The north-northeast-trending P8P9 zone is separated from the North zone by an ephemeral drainage channel. Mineralization is defined over a 1.6 km strike length with a width of 1.4 km at its widest point. Discrete north-northeast higher-grade lenses occur within wide low-grade pyrite-rich zones dipping steeply to the east. Similar to North Hill, zones of flatter lying extensional quartz veining are also present. Mineralization intersected in holes BBD1368, BBD1369 and BBD1370 demonstrate the potential for wide zones of mineralization with no significant expression near surface. Mineralization is hosted within a granodiorite unit with abundant disseminated pyrite with above background gold levels throughout. Of note is hole BBD1370 which returned 1.09 g/t Au over 45.00 m, within one of the widest mineralized intercepts on the property to date of 0.64 g/t Au over 157.00 m. Over all, this stepout drilling at P8P9 was successful in extending this zone of higher-grade mineralization by a further 100 m down plunge. P8P9 zone: selected high-grade subzone intercepts (previously reported):

• 2.04 g/t Au over 35.00 m (BBD0483);
• 1.95 g/t Au over 45.00 m (BBD0522);
• 1.72 g/t Au over 40.40 m (BBD1294);
• 1.06 g/t Au over 44.00 m (BBD1312).

QA/QC (quality assurance/quality control)

The mineralized intervals are based on a lower cut-off grade of 0.28 gram per tonne in the Oxide+Upper Transition zone and 0.45 g/t Au in the Lower Transition+Hard Rock zone. The half-core drilling samples were cut using a diamond saw by Orezone employees. The samples were prepared by BIGS Global Burkina Sarl and then split by Orezone to one kilogram using rotary sample dividers (RSDs). A one-kilogram aliquot was analyzed for leachable gold at BIGS Global in Ouagadougou, by bottle-roll cyanidation using a LeachWell catalyst. The leach residues from all samples with a leach grade greater than or equal to 0.25 g/t Au 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-per-cent standards, blanks and duplicates. The composite width and grade include the final leach residue assay results for most of the drill intercepts reported.
