Patrick Downey, President and CEO, commented “These latest exploration drill results continue to demonstrate the growth potential at Bomboré, confirming the continuity of gold mineralization beyond the current Mineral Resources and Mineral Reserves.

Step-out drilling continues to highlight significant exploration upside along strike, demonstrated by follow-up drilling at P16, that confirmed the zone’s 600 metre strike extension and its overall sub-parallel orientation to the P17 high-grade trend. As with P17, the emerging P16 trend hosts notably higher-grade zones within a broader envelope of lower grade mineralization. Ongoing structural studies and future exploration drilling will focus on refining the controls and continuity of these higher-grade zones, which are potentially amenable to underground mining and could significantly enhance the production profile.

In addition to our successful expansion drilling programs, the 2026 resource definition program focused on converting Inferred Resource to the Indicated category, supporting a Mineral Resource and Mineral Reserve update which is expected to be released in the first quarter of 2027. The updated estimate will incorporate the results of approximately 100,000m of additional drilling, in addition to an adjusted cut-off grade reflective of current operating costs and higher gold prices. Given Orezone’s ongoing exploration success in extending mineralization to depth and along strike, we expect that the new estimate will yield a material increase to both Mineral Resources and Mineral Reserves, further extending the overall life-of-mine at Bomboré”.

Exploration Drilling Results

Follow-up drilling at P16 was successful in confirming the P16 strike extension, which has now been traced over 600 metres to the northeast of the established P16 Mineral Resource. This newly emerging trend is subparallel to the established P17 Trend, located approximately 1 kilometre to the southeast. As with the P17 Trend, P16 hosts notably higher-grade zones, with mineralization plunging at 25 degrees to the north-northeast, parallel to the axes of tight folds in quartz veins. Follow-up drilling at P16 will look to both delineate mineralization along the broader trend, as well as to further refine the continuity of the higher-grade zones with increasingly tighter drill spacing.

The P16 strike extension is a significant discovery that has broader implications in terms of future resource growth within the Bomboré gold system. P16 strike extension was not previously recognized as a prospective target because of the approximately eight metres of Tertiary cover that masks the underlying mineralization. This recent finding opens up multiple areas under cover that were not previously advanced due to the absence of surficial geochemical anomalies.

Resource Definition Drill Results
For 2026, Orezone has budgeted approximately 65,000m of drilling at Bomboré, with 45,000 metres dedicated to resource definition drilling. The definition program follows more recent 100 metre-spaced step-out drilling, which was successful in extending gold mineralization below several of the current life-of-mine resource pits. Targeted infill drilling is expected to expand the existing resource base, with future pit optimizations potentially extending pit boundaries further down depth and along strike.

Further to the planned 2026 step-out and resource definition drill programs, mineralization at Bomboré remains open at depth and along strike. To date, the broader mineralized system has been traced across a continuous 14-kilometre strike length, with Mineral Reserves to an average depth of less than 40 metres and Mineral Resources to an average depth of approximately 70 metres. Future definition drilling at Bomboré will be focused on delineating higher-grade centers of mineralization, with the potential to be sequenced into the near-term mine plan, supporting further growth in production and operating cash flow.

Section 1 – Sampling Techniques and Data

Criteria	JORC Code Explanation	Commentary
Sampling techniques	Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling. Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases, more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information.	Reverse circulation (RC) drill samples are collected every metre for the entire length of the borehole. All material from each meter was sampled via conical splitter attached to the RC rig cyclone. This produces a 2-3kg sub-sample which is collected in a prelabelled sample bag with sequential sample numbers. Historical RC sampling includes collecting the cyclone underflow sample, splitting in a rotary sample divider to generate a RC sub-sample with a mass of ±2.1 kg. HQ and NQ drill core samples are collected from half-drill core cut evenly lengthwise with a diamond saw at regular 1 m intervals. Sampling per geological contacts is permitted ± 0.2m either side of the meter mark. Samples are numbered and bagged before dispatch to the laboratory. Samples were consistently cut on a nominal 10 degree rotation from the orientation line mark on the core (where orientation available, otherwise a consistent cut-line is established) and the non-orientation/cut-line marked side of the core is submitted for assay. Samples were submitted to BIGS Laboratory in Ouagadougou after drying, the entire sample is crushed to 6 mm and pulverised to achieve 85% passing 106 μm. The pulverised samples are returned to site and rotary split to 1 kg for use as original samples and duplicates. Samples are returned to BIGS for Au determination by 1kg LeachWELL with atomic absorption spectrometry (AAS) finish.
Drilling techniques	Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc.).	RC drilling was undertaken using a contractor owned rig with auxiliary air. 4” or 4 1/2” face sampling hammers are used. Diamond drill core material from both surface drilling and pre-collars is collected from a combination of HQ and NQ diameter diamond drilling (collaring in HQ and change over to NQ diameter in fresh rock) obtained by wireline drilling with standard tube. Core orientations were completed using Reflex ACT III RD and ACTx orientation tools with the orientation line marked up at the rig side and reviewed by geologists in the core shed.
Drill sample recovery	Method of recording and assessing core and chip sample recoveries and results assessed. Measures taken to maximise sample recovery and ensure representative nature of the samples. Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material.	Diamond core recoveries are measured in the core trays and recorded as recovered meters and recovered % as part of the geological logging process. RC sample recovery was qualitatively logged with weights of bulk samples recorded at the rig side. Sample recovery and integrity was maximised by drilling with sufficient air pressure to maintain dry samples with holes stopped if significant water ingress. Dry, moist or wet samples are recorded in the database. Examination of the RC and DD composite grade distributions suggests a slight positive bias between the RC and DD composite sample populations at grades <0.15 g/t, and a negative bias between these two populations at grades higher than 0.20 g/t. These biases are not considered critical, and no correction factors were applied.
Logging	Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. The total length and percentage of the relevant intersections logged.	Logging protocols were followed to a level of detail suitable for support of the Mineral Resource and Ore Reserve estimate. Both RC chip samples and core samples include quantitative analysis (Niton XRF) and photographs. Core sample logging included qualitative data such as lithology, weathering intensity, competence (RQD) and discontinuities. All reported drilling is logged in its entirety.
Sub-sampling techniques and sample preparation	If core, whether cut or sawn and whether quarter, half or all core taken. If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. For all sample types, the nature, quality and appropriateness of the sample preparation technique. Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. Measures taken to ensure that the sampling is representative of the in-situ material collected, including for instance results for field duplicate/second-half sampling. Whether sample sizes are appropriate to the grain size of the material being sampled.	Core samples are collected from half-drill core cut lengthwise with a diamond saw. RC samples representing a 1/8 split of each meter drilled are collected from a rig-mounted cone splitter. Drilling is discontinued if dry sample is unable to be maintained. Field duplicates are collected from the RC rig splitter and inserted into the regular sample stream every 50 samples. Mineralised RC field duplicates for 2025 drilling are within 1 % of the original split. Lab-aware pulp duplicates a inserted every 25 samples for diamond core samples. For both RC and DD samples, the entire sample is crushed and pulverised with >85% passing 75microns. The 2-3 kg sample size is deemed appropriate given that the gold occurs as fine grained electrum.
Quality of assay data and laboratory tests	The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. For geophysical tools, spectrometers, handheld XRF instruments, etc., the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established.	Reviews of the sampling, analytical, and quality assurance and quality control (QA/QC) protocols used on the RC and core programs have been completed and acceptable levels of accuracy have been achieved. No geophysical tools, spectrometers, or handheld XRF instruments have been used in the reported exploration results to determine chemical composition at a semi-quantitative level of accuracy. Assaying for gold is by the LeachWELL bottle roll cyanide leach method. Gold content in the solution is determined using atomic absorption analysis. For all the samples having liquor grade >0.2 g/t Au, the tail is washed, dried and a 50 g charge is split and submitted for assaying using a conventional fire assay procedure on 50 g sub-sample. The QA/QC protocol since 2011 is to submit 2% Blind Field Duplicates, 3% Blind Pulp Duplicates, 5% Lab Aware Pulp Duplicates, 2% Blind Blanks and 3% Blind Standards. The laboratory inserted commercial standards and completed repeat assays. Repeat or duplicate analysis for samples shows that the precision of samples is within acceptable limits, and a review of results from both laboratory and Company inserted commercial standards indicate acceptable levels of accuracy have been established.
Verification of sampling and assaying	The verification of significant intersections by either independent or alternative company personnel. The use of twinned holes. Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. Discuss any adjustment to assay data.	The Competent Person has confirmed the sample preparation, security, analytical procedures and QA/QC undertaken are adequate for the purposes of Mineral Resource estimation and that there are no factors that materially impact the reliability or accuracy of the dataset employed in the calculation. Data acquisition is completed on a combination of paper log sheets, and entry into a self-validating data entry software package (LogChief). Integrated datasets have been uploaded to the Company’s SQL hosted database and archived on physical back-up drives. There are no twinned holes. Below detection limit values (negatives) have been replaced by background values.
Location of data points	Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Specification of the grid system used. Quality and adequacy of topographic control.	The borehole collars are spotted in the field and pegged using a differential global positioning system (DGPS) set to achieve sub-metre accuracy. Post drilling, the completed holes are surveyed by Bomboré mine surveyors using Trimble GNSS with correction by real time kinematic (RTK) to ensure sub decimeter accuracy. Grid system is based on the UTM30N grid on the WGS84 ellipsoid. Down hole surveys were undertaken by the Company using a Reflex Ez-Trac tool and Reflex OMNI Gyro with readings measured in continuous and multishot mode with readings taken between 10-30m. Holes are validated in IMDEX Hub prior to inclusion in the drillhole database. Azimuths measured using magnetic fields are converted to a geographic azimuth using the declination applicable at the time of the survey.
Data spacing and distribution	Data spacing for reporting of Exploration Results. Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. Whether sample compositing has been applied.	Data spacing is variable across the deposit, ranging from 50x50m at the periphery to 25x25m in the more densely drilled core. The oxide resources have been defined along 50 m-spaced drill sections with 25 m between the drill collars. The hard rock resources have been defined generally along 50 m-spaced drill sections with 50 m between the drill collars. Drill samples were composited to 1m for use in resource estimation. Mining at Bomboré has demonstrated reasonable continuity over a strike of 10 km at a cut-off grade of 0.15 g/t Au. At this cut-off grade, the gold mineralisation forms corridors 500 m to 1,000 m in length and 10 m to 100 m in width. At a cut-off grade of 0.5 g/t Au, the higher-grade subdomains have a strike length of up to 500 m and a width typically between 5 m and 30 m. Support of the strong continuity of mineralisation along strike has been confirmed by mining production and mapping of pit walls and floors.
Orientation of data in relation to geological structure	Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material.	In all areas, the drilling direction is opposite to the dip and orthogonal to the average strike of the lithological units, major fabrics, and wireframed mineralised domains. The plunge of the boreholes at the collar is generally 50° ±5°, thereby intersecting the lithological units, major fabric and wireframed mineralised domains at an angle between 65° and 90°. No sampling bias was deemed to have occurred.
Sample security	The measures taken to ensure sample security.	Strict security measures are applied throughout the sampling, sample preparation, and analytical stages. The RC samples and the drill core retrieved by the drillers are collected and handled at the drill site by Orezone personnel. The sample bags are transported by a dedicated driver to a secure storage area in the Bomboré Gold Project area. The sample storage area at the Bomboré Gold Project is fenced and a watchman provides full-time security. Finally, the samples are dispatched to the analytical laboratories under the direct control of Orezone staff, who monitor the preparation and shipment of the samples. This procedure ensures reasonable chain of custody by Orezone from the drill sites to the analytical laboratory.
Audits or reviews	The results of any audits or reviews of sampling techniques and data.	In 2017, Mr Yassa collected 50 samples from 15 RC boreholes and 35 cored boreholes during the site visit for independent analysis of gold content. There was a good correlation between the independently collected verification samples analysed at SGS and the Orezone data.

Section 2 – Reporting of Exploration Results

Criteria	JORC Code Explanation	Commentary
Mineral tenement and land tenure status	Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.	The Project covers an area of 12,963 ha and consists of one Industrial Operating Permit (the Bomboré Mining Permit) of 2,887 ha, surrounded by four Mining Exploration Permits: the Bomboré II Exploration Permit of 1,265 ha, the Bomboré III Exploration Permit of 3,360 ha, the Bomboré IV Exploration Permit of 833 ha and the Bomboré V permit of 4,618 ha. The Bomboré Mining Permit is registered in the name of Orezone Bomboré S.A. (OBSA), a 90%-owned subsidiary of Orezone Inc. S.A.R.L, itself a 100%-owned subsidiary of Orezone Inc., which is 100% owned by Orezone. The Bomboré Mining Permit was granted to OBSA by way of Decree No. 2016-1266/PRES/PM/MEMC/MINEFID/MEEVCC dated 30 December 2016 and is valid for an initial tenure of 10.7 years but can be extended if the mine life is extended beyond what was initially applied for. All mining ventures in Burkina Faso are subject to a 10% free carried interest and a royalty on gold sold in favour of the Government of Burkina Faso, upon the award of an operating permit from the government.
Exploration done by other parties	Acknowledgment and appraisal of exploration by other parties.	Between 1989 and 2000, mineral exploration programs were completed by La Générale des Mines et des Carrières (GMC), Channel, Solomon, and Placer Dome. A total of 1,271 core, RC and rotary air blast (RAB) boreholes were completed. Channel completed 10 diamond boreholes for approximately 1,100 m, 261 RC boreholes for approximately 20,000 m, and 1,000 RAB boreholes for approximately 34,000 m.
Geology	Deposit type, geological setting and style of mineralisation.	Bomboré is an orogenic gold deposit, exhibiting structural control and associated hydrothermal alteration mineral assemblages. The deposit represents a large tonnage, low-grade gold mineralisation system similar to other Birimian gold deposits, such as Kiaka in Burkina Faso, Damang, Yamfo-Selwi in Ghana, and Sadiola in Mali. The geological setting is part of a northeast–southwest trending greenstone belt extending for 50 km. The permit area is underlain mainly by a metasedimentary flysch-type sequence dominated by metasandstones with subordinate carbonaceous meta-pelites and polymictic metaconglomerates. The Bomboré gold deposits occur within a major north to northeast trending structure. The gold deposits were discovered by tracing gold-in-soil anomalies to bedrock by drilling. Gold mineralisation is associated with arrays of structurally controlled quartz veins and veinlets and attendant silica, sulphide, and carbonate alteration.
Drill hole Information	A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: easting and northing of the drill hole collar elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar dip and azimuth of the hole down hole length and interception depth hole length. If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case.	The Bomboré mine commenced production in 2022. The Mineral Resource estimate includes a total of 6,322 RC drill holes and 1,426 diamond drill core holes. The Competent Person has determined that the detailed information on the drill holes is not material and does not detract from the understanding of the report.
Data aggregation methods	In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated. Where aggregate intercepts incorporate short lengths of high-grade results and longer lengths of low-grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. The assumptions used for any reporting of metal equivalent values should be clearly stated.	All intersections are assayed on predominantly 1 m intervals and no top-cuts are applied to exploration results. Reporting of mineralised intervals is based on a lower cut-off grade of 0.28 g/t in the Oxide+Upper Transition zone, and 0.45 g/t Au in the Lower Transition+Hard Rock zone, with a minimal width of 1.5 m and up to a maximum of 3.0 m of dilution being included.
Relationship between mineralisation widths and intercept lengths	These relationships are particularly important in the reporting of Exploration Results. If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true width not known’).	The majority of the drilling was planned to intersect mineralisation in a perpendicular manner or as close as practicable. The true width of the mineralisation to drill core length: -Siga: 80-100% -P8P8 & P17: 75-85% -North Zone: 60-80% -P16: Yet to be determined
Diagrams	Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include but not be limited to a plan view of drill hole collar locations and appropriate sectional views.	Appropriate diagrams have been included for reporting of significant intercepts.
Balanced reporting	Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results.	All grades, high and low, are reported accurately with ‘from’ and ‘to’ depths and ‘hole identification’ shown.
Other substantive exploration data	Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances.	All material exploration data including metallurgical test results have been reported.
Further work	The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling). Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.	In 2024 Orezone designed an initial 30,000 m first pass exploration drill program, that will test multiple targets across the greater than 14 km long mineralised system. This initial program will be used to refine target priority for subsequent exploration drilling in this multi-year campaign, as well as to advance the project’s evolving structural framework. Phase 1 of this initial program will be centred on the North Zone and thereafter, drilling will progressively advance towards the southern half of the mining lease. First pass drilling along the Bomboré Shear Zone (BSZ) will be focused on testing the potential of the mineralised system to depths of up to 400 m. While drilling will be wide spaced in nature, the objective will be to increase pit depths longer-term, as well as to illustrate the broad continuity of multiple higher grade plunging zones of mineralisation that are well defined by shallower drilling and current mining operations. These higher-grade plunging sub-zones may further support an underground mining scenario later in the project’s mine life, once high-grade near-surface open pits are depleted.
