Orezone Gold Corporation (TSX: ORE) (ASX: ORE) (OTCQX: ORZCF) is pleased to provide additional drill results from its ongoing multi-year exploration campaign at its flagship Bomboré Gold Mine. The latest results are from the North and P8P9 zones, targeting the down plunge continuity of higher-grade sub-zones beneath the current life of mine pits.

Selected Drill Highlights¹:

• 1.59g/t Au over 48.00m, including 4.86g/t Au over 9.00m (BBD1358)
• 1.09g/t Au over 45.00m, including 2.56g/t Au over 8.00m (BBD1370), within a broader mineralized intercept of 0.64g/t Au over 157.00m²
• 1.97g/t Au over 16.10m, including 2.74g/t Au over 10.10m (BPC7217)
• 2.01g/t Au over 14.00m (BPC7216)
• 2.67g/t Au over 7.40m (BBD1367)
• 1.63g/t Au over 11.00m (BPC7216)
• 1.48g/t Au over 8.75m (BBD1369)
• 1.82g/t Au over 6.40m (BPC7210)
• 1.16g/t Au over 9.00m (BBD1369)
• 1.47g/t Au over 6.50m (BBD1368)
• 1.01g/t Au over 9.00m (BPC7217)

Patrick Downey, President and CEO stated, “These latest drill results confirm the down plunge continuity of multiple higher-grade sub-zones, 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 Bomboré to selectively pull higher-grade reserve pits to depth across the greater 14km long reserve defined trend. Of particular significance is the very broad sub-zone 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 Bomboré, demonstrating significant exploration potential.

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

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

Drilling will continue in H2-2025 on multiple fronts in support of the Company’s long-term goal of increasing Bomboré’s current stated global resource from 5 million ounces⁴ to a targeted 7 to 10 million ounces longer term.⁵ This is truly an exciting prospect with the ongoing hard rock expansions positioned to increase Bomboré’s overall production to 220,000-250,000 ounces per annum.⁶”

North & North Hill Zone

The ongoing drilling program continues to define and expand mineralized trends along the 3km 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 on-going 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 sub-zone beneath the life of mine reserve pit (including intercepts of 1.59g/t Au over 48.00m and 1.97g/t Au over 16.10m), and 2) further delineating higher-grade mineralization within the west dipping footwall shear (2.01g/t Au over 14.00m). Both of these higher-grade trends remain open to depth, and will be the focus of future follow-up drilling.

North Hill Zone: selected high-grade sub-zone intercepts (previously reported⁷):

• 5.35g/t Au over 21.00m (BBD1220)
• 3.14 g/t Au over 18.00m (BBD1285)
• 3.30g/t Au over 20.00m (BBD1219)
• 2.55 g/t Au over 23.00m (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 1.6km strike length with a width of 1.4km 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 1.09g/t Au over 45.00m, within one of the widest mineralized intercepts on the property to date of 0.64g/t Au over 157.00m⁸. Overall, this step-out drilling at P8P9 was successful in extending this zone of higher-grade mineralization by a further 100m down plunge.

P8P9 Zone: selected high-grade sub-zone intercepts (previously reported⁹):

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

QA/QC

The mineralized intervals are based on a lower cut-off grade of 0.28g/t in the Oxide+Upper Transition zone, and 0.45g/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 s.a.r.l. (“BIGS Global”) and then split by Orezone to 1 kg using Rotary Sample Dividers (“RSDs”). A 1kg aliquot was analyzed for leachable gold at BIGS Global in Ouagadougou, by bottle-roll cyanidation using a LeachWellTM catalyst. The leach residues from all samples with a leach grade greater than or equal to 0.25g/t Au were prepared by BIGS Global and then split by Orezone to 50g using RSDs. A 50g aliquot was analyzed by fire assay at BIGS Global.

Orezone employs a rigorous Quality Control Program including a minimum of 10% standards, blanks and duplicates. The composite width and grade include the final leach residue assay results for most of the drill intercepts reported.
