VANCOUVER, British Columbia, May 19, 2026 (GLOBE NEWSWIRE) -- Orezone Gold Corporation (TSX: ORE | ASX: ORE | OTCQX: ORZCF)(the “Company” or “Orezone”) is pleased to announce the first set of drill results from its recently acquired Casa Berardi gold mine, located in Quebec, Canada.

Selected Drill Highlights1:

| - 6.47g/t over 21.5m(CBF-160-233) | - 7.20g/t over 14.9m (CBF-134-125) | | _Incl. 8.94g/t over 12.7m

_ | _Incl. 16.18g/t over 3.4m

_ | _Incl. 9.33g/t over 3.5m

_ | | - 6.92g/t over 7.5m (CBF-134-127) | - 11.97g/t over 3.5m (CBF-134-135) |

Patrick Downey, President and CEO, commented_“We are extremely pleased to release this first set of drill results from Casa Berardi, which clearly demonstrates the mine’s significant and untapped exploration upside. The results are from the near-surface F160 and F134 zones, and serve to support planned pit expansions, and more importantly, further illustrate the down-plunge continuity of high-grade mineralization in each zone. Taken together with historical drill results, these plunging zones of mineralization represent potential future underground mining centers, which are located proximal to existing underground infrastructure._

In addition to ramping-up underground exploration drilling at Casa Berardi, surface drilling of the F160 and F134 zones will remain ongoing. The delineation of F160 Zone at depth is expected to further supplement the Company’s plans to increase underground mining rates by reopening the East Mine, while future step-out drilling down plunge of the F134 Zone has the potential to open a significant new exploration front in the Gap Zone.

Overall, we are incredibly encouraged by these initial drill results at Casa Berardi, and look forward to providing regular exploration updates as we incrementally ramp-up exploration to a sustained 80,000-100,000m/yr.”

F160 Zone The F160 Zone hosts the operating F160 pit, which is located adjacent to the Casa Berardi process plant. Mineralization is open outside of the current F160 life-of-mine pit, with mineralized lenses plunging both to the east and west at 30-40 degrees. Ongoing drilling within the F160 Zone remains focused on testing the down-plunge continuity of high-grade mineralization, with trade-off studies underway to evaluate an expanded F160 pit and a future transition to underground mining.

Initial 2026 drilling of the F160 Zone returned several significant intercepts, including1:

Furthermore, as detailed in Figure 2, several notable historical results support the broader continuity of mineralization at depth, which include1:

F134 Zone The F134 Zone comprises multiple near-surface lenses of mineralization, plunging to the east at 40-50 degrees. The zone hosts the undeveloped F134 pit, with distal mineralization traced a further 750m down plunge below the current designed pit limits. Ongoing drilling within the F134 Zone remains focused on 1) infill drilling to support an expansion of the F134 pit, and 2) down plunge infill and step-out drilling targeting high-grade veins in support of future underground mining. As drilling continues to ramp-up at Casa Berardi, one of the priority targets moving forward will be the broader delineation of mineralization down plunge of the F134 Zone into the Gap Zone, which has seen limited drilling to date.

Initial 2026 drilling of the F134 Zone returned several significant intercepts, including1:

As detailed in Figure 3, there are several notable historical results which illustrate the broader continuity of mineralization at depth including1:

Casa Berardi Exploration Outlook Exploration drilling at Casa Berardi has recently been reinitiated, with four exploration rigs now turning and a fifth to be added in early June. The Company plans to complete 40,000-60,000m of exploration drilling this year at Casa Berardi, with plans to systematically ramp up to a sustainable 80,000-100,000m/yr moving forward.

The 2026 exploration program commenced with surface drilling at the F160 and F134 zones, with ongoing drilling targeting down-plunge extensions at each zone. These near-surface zones, which are proximal to existing underground infrastructure, represent significant and actionable exploration targets, and have the potential to materially expand the current underground resource (M&I: 4.89Mt at 5.93g/t Au containing 934,000oz, Inferred: 1.91Mt at 7.02g/t Au containing 432,000oz).2

More recently, underground drilling has commenced in the 118N Zone (~800m depth from surface) as a follow-up to several significant historical intercepts on the north side of the Casa Berardi fault. Given that the vast majority of underground mineralization identified to date at Casa Berardi is located on the south side of the fault, this exploration upside to the north has significant potential implications in-terms of future resource and production growth moving forward. We see supporting evidence for this thesis in the open pits, where mineralization along secondary and tertiary structures to the north of the Casa Berardi fault has locally been traced beneath the pits to depth of ~350m from surface.

Selected 118N Zone historical intercepts:

| 269.78g/t Au over 1.0m (CBP-1440)

14.34g/t Au over 2.6m (CBW-1018)

11.53g/t Au over 3.0m (CBW-1440) |

As exploration drilling continues to ramp-up at Casa Berardi, future targets include the down-plunge delineation of the well-established WMCP and Principal ore shoots at depth. In support of this drilling, the Company has mobilized an underground mining contractor to site, which in addition to increasing mine development rates, will be utilized to establish the requisite drill stations for this targeting.

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. | - Pre-production drilling NQ drill core samples are collected from whole core samples at a minimum interval of 0.5m and a maximum of 1.0m. Samples are numbered and bagged before dispatch to the mine laboratory. Definition drilling NQ drill core samples are collected from half drill core cut evenly lengthwise with a diamond saw at a minimum interval of 0.5m and a maximum of 1.0m. Samples are numbered and bagged before dispatch to the mine laboratory. Remaining half core is kept on site as control sample. Exploration drilling NQ drill core samples are collected from half drill core cut evenly lengthwise with a diamond saw at a minimum interval of 0.5m and a maximum of 1.0m. Samples are numbered and bagged before dispatch by truck to the external lab Swastika Laboratory in Timmins, Ontario. Remaining half core is kept on site as control sample. Mine laboratory samples is split and submitted for assaying using a conventional fire assay procedure on 15 g sub-sample. Remaining sample pulps is kept for a limited time depending on the drilling purpose. Swastika laboratory samples is split and submitted for assaying using a conventional fire assay procedure on 50 g sub-sample. | | 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.). | - The Mineral Resource estimate includes a total of drill 17,271 diamond drill core holes. Core drilling is the unique drilling technique used to explore, define and delineate mineralized zones. Most drilling used NQ core barrel and sometime HQ and BQ for deeper holes or to telescope through the Casa Berardi fault. Core is oriented via a downhole survey of the boreholes using Reflex Instruments EZ-TRAC and Gyroscope. Downhole surveys were completed on all holes at intervals of 3m. All data is validated by the mine professional geologist. | | 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. | - Recovery from core holes is nearly 100%, the Casa Berardi fault being most of the time where core recovery is difficult. There is no relationship between sample recovery and grade. | | 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. Core sample logging included qualitative data such as lithology, alteration, mineralization, competence (RQD) and discontinuities. All core is photographed. | | 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 whole (Pre-production drilling) and half-drill core (Definition and Exploration Drilling) cut lengthwise with a diamond saw. All whole core samples sent to the mine laboratory, which weigh approximately 10kg each, are entirely crushed to 80% passing (P80) 6.3mm in a jaw crusher. Approximately 200g to 250g of split material is crushed to a 95% minus 150-mesh or 85% minus 200-mesh sample pulp using a ring-and-puck pulverizer. The pulp is laid down on a rubber mat and homogenized. A 15g sub-sample is then collected, weighed, and analyzed by fire assay with an atomic absorption spectrometer (AAS) finish. All results, reported in grams per tonne, are sent electronically to the mine geology department. Samples sent to Swastika Laboratory are dried in an oven at 80°C and then are entirely crushed to P80 1.7mm with a jaw crusher and split with a rotary splitter. Approximately one kilogram of the jaw-crushed sample is entirely pulverized to 90% minus 107μm in a ring-and-puck pulverizer. All pulverized material is placed on a rubber mat, homogenized, and transferred into disposable brown paper bags for weighing. A 30g aliquot of pulverized material is split out and analyzed by fire assay with an AAS finish. A second fire assay analysis is completed with a gravimetric finish for samples with gold results above 10g/t Au. | | 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 core programs have been completed and acceptable levels of accuracy have been achieved. Gold content in the solution is determined using atomic absorption analysis. The QA/QC protocol since 2006 on core is to submit 5% coarse reject duplicates, 5% Pulp Duplicates, 5% Blanks and 4% Standards. | | 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 the Mineral Resource estimate and that there are no factors that materially impact the reliability or accuracy of the dataset employed in the calculation. There are very few twinned holes. | | 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 diamond drill hole collars are spotted in the field and pegged using a differential global positioning system (DGPS) set to achieve sub-metre accuracy. Underground diamond drill hole collars are spotted using a station total and underground surveyed plugs. The downhole survey of the boreholes was surveyed using a Reflex Instruments that measures several parameters, including the plunge of the borehole and the three components of the magnetic field. It relies on a compass to read the azimuth. The azimuth angles are validated against the measured intensity of magnetic field, and an accelerometer reading to ensure the compass was stable when measurements were taken. The magnetic azimuth is converted to the mine grid system. Downhole surveys are also surveyed with gyroscope (DeviGyro) for sector with BIF and deep holes. | | 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. | - Underground Inferred Mineral Resources: Blocks in modelled mineral envelopes outside a mean distance of ~25m. The mean distance of Inferred Mineral Resources is generally between 25m and 35m, and rarely up to 50m. Inferred Resources: Blocks in modelled mineral envelopes outside a mean distance of ~35m. The mean distance of Inferred Mineral Resources is generally 60m or less. Down-hole composite length applied to samples used for underground and open pit estimation is 1.0m and 2.5m, respectively. Casa Berardi is an orogenic gold deposit with reasonable continuity along vicinity of the Casa Berardi fault corridor. Support of the strong continuity of mineralisation along strike and at depth has been confirmed by few exploration holes, mapping of pit walls and underground development. | | 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. | - Drilling direction is generally opposite to the dip and orthogonal to the average strike of the lithological units, major fabrics, and wireframed mineralised domains. Drilling is favourably oriented south to north due to the average 70° south plunge stratigraphy. No sampling bias was deemed to have occurred. | | Sample security | - The measures taken to ensure sample security. | - Security measures are applied throughout the sampling, sample preparation, and analytical stages. The drill core retrieved by the drillers are collected and handled at the drill site by the drilling contractor. The sample bags are transported to the mine lab by the sample preparation technician. Finally, the exploration core samples are dispatched to the external laboratory by the laboratory driver. | | Audits or reviews | - The results of any audits or reviews of sampling techniques and data. | - In 2024, an independent audit of the 2021, 2022 and 2023 assay data for the Casa Berardi Mine was completed with acceptable results. The audit concluded that the drill-hole database is sufficient for geological and mineral domain modelling, mineral resource and mineral reserve estimation, and mine planning. Sampling and assaying methods used in the current program are consistent with those used in 2023. |
