MONTREAL, Feb. 11, 2026 (GLOBE NEWSWIRE) -- Osisko Development Corp. (NYSE: ODV, TSXV: ODV) ("Osisko Development" or the "Company") is pleased to announce new infill drilling results from its ongoing 13,000-meter program on 10 meter drill spacing that commenced in August 2025 in the Lowhee Zone of the Company's permitted, 100%-owned Cariboo Gold Project ("Cariboo" or the "Project"), located in central British Columbia ("B.C."), Canada. The six drill hole fans reported herein comprise an additional ~5,043 meters ("m") of underground infill drilling, bringing the total tally of drilling with full results to 11,025 m, or ~80% of the planned total.
Chris Lodder, President, stated, "This tighter drill spacing gives us a better understanding of vein corridor spatial geometries and local variability specific to this part of the Lowhee deposit, while reinforcing the importance of continued drilling in underexplored zones. As this work concludes, the resulting information is expected to help refine infill drill requirements and production designs and sequencing in the Lowhee Deposit of the Cariboo Gold Project."
In total, an aggregate of approximately 12.1 kilometres ("km"), representing ~88% of the total planned drill meters, has now been completed. Full assay results and associated quality assurance and quality control reviews are pending for the remaining holes not reported herein. Infill drilling activities were suspended following the incident reported on January 23, 2026, with the program now anticipated to conclude in early Q2 2026.

DISCUSSION OF RESULTS
- Based on the results observed to date, the above cut-off assay composites show a general spatial correlation with the modelled reserve stopes. Individual intercepts are not expected to align precisely with the modelled areas, and a degree of variability within the vein corridors is both anticipated and acceptable as tighter spaced infill drilling informs a refinement of the local reserve model. This work is one of the key objectives of the ongoing program.
- Occurrences of above cut-off assays are also being observed in areas not previously included in the reserve model, suggesting potential for upside mineralization. These intervals will be incorporated in the planned remodelling and mineral resource calculation process to determine their implications on the updated local block model and any potential adjustments to planned reserve stopes. In certain areas, this may support the addition of new planned reserve stopes, subject to the final estimation process outcome.
- A spatial offset of certain intercepts when compared to the modelled vein corridors
and mineral reserve stope shapes is evident in the cross sections. This reflects, in part, the lower spatial accuracy of the surface-based
drill hole data compared to underground drilling, which carries higher survey precision, as well as the more oblique angles of intercepts
that the surface-based drill holes have with the vein planes. These factors will be accounted for in the vein corridor remodelling process
to be undertaken upon conclusion of this program and will serve as an important operational template for future infill drilling used in
production stope design.

ABOUT LOWHEE ZONE
Geological mapping and geochemical sampling were carried out on Barkerville Mountain from 2017-2018, with the Lowhee Zone identified as a high-priority drill target. From 2019 to 2022, a total of 167 surface drill holes were completed, totaling 54,494.5 m.
Lowhee zone access is through Cow portal on the northwestern flank of Barkerville Mountain (Figure 1 and Figure 2) Cow portal construction was completed in Q4 2024 and development of the underground ramp into the Lowhee zone commenced in Q1 2025. Approximately 350 m of development has been advanced within the Lowhee zone deposit at the 1,290 and 1,260-elevation levels since completion of the main access ramp. The probable mineral reserves estimate for the Lowhee Zone includes 104,491 ounces of contained Au (923,162 tonnes grading 3.52 g/t Au) and represents approximately 5% of the total contained gold in the estimated probable mineral reserves for the Cariboo Gold Project.
ABOUT CARIBOO GOLD PROJECT
The Cariboo Gold Project is a permitted, 100%-owned feasibility-stage project located in the historic Wells-Barkerville mining camp of central British Columbia, Canada. Spanning approximately 186,740 hectares, the Company’s land package includes 443 mineral titles and covers a ~83-kilometre strike of highly prospective exploration targets extending northwest to southeast. In late 2024, the Project was granted the Mines Act and Environmental Management Act (British Columbia) permits, marking the successful completion of the permitting process for key approvals, solidifying the Project's shovel-ready status.
The Cariboo Gold Project hosts probable mineral reserves of 2.071 million ounces of contained Au (17,815 kt grading 3.62 g/t Au); measured mineral resources of 8,000 ounces of contained Au (47 kt grading 5.06 g/t Au); indicated mineral resources of 1.604 million ounces of contained Au (17,332 kt grading 2.88 g/t Au); and inferred mineral resources of 1.864 million ounces of contained Au (18,774 kt grading 3.09 g/t Au). Mineral resources are reported exclusive of mineral reserves.

Qualified Persons
The scientific and technical information contained in this news release has been reviewed, verified and approved by Scott Smith, P. Geo., Vice President, Exploration of Osisko Development, a "qualified person" within the meaning of NI 43-101. Verification includes core photo and three-dimensional review of logged drillhole data and assays consistent with the Company's standard operating procedures.
Quality Assurance (QA) – Quality Control (QC)
Whole core sampling was used for all HQ core completed in the logging facilities following daily QAQC checks for logging and sampling errors. Quality control (QC) samples are inserted at regular intervals in the sample stream, including blanks and reference materials with all sample shipments to monitor laboratory performance. Samples are bagged, labeled, sealed with numbered security tags
Samples are taken by expeditor from the logging facilities direct to MSALABS’s analytical facility in Prince George, B.C., Canada, for preparation and analysis. The MSALABS facility is accredited to the ISO/IEC 17025 standard for gold assays and all analytical methods include quality control materials at set frequencies with established data acceptance criteria. The entire sample is dried, crushed, and split into sealed containers. Analysis for gold is by gamma ray analysis using the Chrysos PhotonAssay (PA1408X). Samples are bombarded with gamma rays and the resulting signal is sent to the detectors.
Alternatively Drill core samples are submitted to ALS Geochemistry’s analytical facility in North Vancouver, British Columbia for preparation and analysis. The ALS facility is accredited to the ISO/IEC 17025 standard for gold assays and all analytical methods include quality control materials at set frequencies with established data acceptance criteria. The entire sample is crushed, and 250 grams is pulverized. Analysis for gold is by 50 gram fire assay fusion with atomic absorption (AAS) finish with a lower limit of 0.01 ppm and upper limit of 100 ppm. Samples with gold assays greater than 100 ppm are re-analyzed using a 1,000-gram screen metallic fire assay. A selected number of samples are also analyzed using a 48 multi-elemental geochemical package by a 4-acid digestion, followed by Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES) and Inductively Coupled Plasma Mass Spectroscopy (ICP-MS).
