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
August 19, 2025 – Vancouver, BC - Orezone Gold Corporation (TSX: ORE | ASX: ORE | OTCQX: ORZCF)
(the “Company” or “Orezone”) 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 ounces 4 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 3 km 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.
3. The drill results were previously disclosed in the Company’s press releases dated June 10, 2025 and January 26, 2025. See also Table 2.
4. Refer to the Company’s prospectus dated and lodged with ASIC on July 11, 2025 (the “ASX Prospectus”), a copy of which is available on the Company’s website for
the Company’s Mineral Resource Estimate: 27,530kt at 0.78g/t Au for 692koz Au Measured Mineral Resources, 151,735kt at 0.78g/t Au for 3,814 koz Au Indicated
Mineral Resources and 20,015kt at 0.95g/t Au for 610koz Inferred Mineral Resources. The Company confirms it is not aware of any new information or data that
materially affects the information included in the Prospectus and that all material assumptions and technical parameters unde rpinning the mineral resources in the
Prospectus continue to apply and have not material ly changed.
5. This statement of the Company’s goal of increasing the current stated 5 million global resource base to a targeted 7 to 10 million ounces longer term is an aspirational
statement, and the Company does not yet have reasonable grounds to believe the statemen t can be achieved.
6. Refer to the ASX Prospectus. The Company confirms it is not aware of any new information or data that materially affects the information incl uded in the ASX
Prospectus and that all material assumptions and technical parameters underpinning the forecast ed gold production targets in the Prospectus continue to apply and
have not materially changed.

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)
