Osisko Development Intercepts 57.29 g/t Gold over 3.05 Meters, 625.95 g/t Gold over 0.5 Meters and 15.26 g/t Gold over 4.4 Meters in Lowhee Infill Drilling at Cariboo Gold Project
ODV NYSE TSXV News Release
OSISKO DEVELOPMENT INTERCEPTS 57.29 g/t GOLD OVER 3.05 METERS, 625.95 g/t GOLD OVER 0.5 METERS AND 15.26 g/t GOLD OVER 4.4 METERS IN LOWHEE INFILL DRILLING AT CARIBOO GOLD PROJECT
Montreal, Québec, September 8, 2025 – Osisko Development Corp. (NYSE: ODV, TSXV: ODV) ("Osisko Development" or the "Company") is pleased to announce results from its infill and exploration diamond drill, and development sampling campaigns in the Lowhee Zone within the Company's permitted, 100%-owned Cariboo Gold Project ("Cariboo" or the "Project"), located in central British Columbia ("B.C."), Canada. The program to date has consisted of approximately 6,471 meters ("m") of underground infill drilling and approximately 398 m of chip and rock saw channel sampling.
Chris Lodder, President, stated, "The recent underground infill drilling at Lowhee Zone was conducted to analyze how grade holds up under tighter drilling and to investigate optimal drill hole spacing for future mining. We're highly encouraged that underground exploration drilling in the Lowhee Zone and across the deposit completed to date continues to indicate that veins remain open at depth, highlighting the strong potential for future resource expansion through additional exploration programs leveraging existing underground infrastructure. A comprehensive 13,000-meter infill drill program is already underway, designed to deliver important data for local resource modeling, mine planning, and optimization of production stope design. We anticipate providing regular progress updates on this program in the coming months."

INFILL AND EXPLORATION PROGRAM SUMMARY
- 14 NQ (47.6-millimeter diameter) diamond drill holes (BMU-25-008 to 021) with depth ranging from 42 to 48 m focused on infilling a 25 m long section of planned ore drive.
- 4 NQ diamond drill holes (BMU-25-001, 003, 004, 007) with an average depth of 290 m were drilled to explore zones adjacent to the existing Lowhee Zone mineral resources.
- 22 NQ diamond drill holes (BMU-25-032 to 053) with an average depth of 90 m conducting systematic grid infill on a set of mineral reserve blocks, mineral inferred resources, and non- DSO resources.
- 8 NQ diamond drill holes (BMU-24-001 to 008) with an average depth of 118 m were drilled infilling areas within existing mineral reserves and resources.
NEXT STEPS
- A 13,000-meter systematic grid infill program is underway within the Lowhee Zone targeting mineral reserve blocks, inferred mineral resources, and non-DSO resources in an approximate 100 m swath transecting approximately the full width of the Lowhee Zone (Figure 3). Drilling at 10 m centers from new development at the 1,260 elevation level, the program is expected to provide a comprehensive data set that will inform resource modeling, mine planning, production stope design procedures and parameters, and the appropriate grid spacing for future infill drilling. Additional systematic grid infill drill programs are planned in step with future underground development progress into other areas of the deposit.
- Structural modelling suggests that the sandstone rock package, the primary host rock for the Cariboo deposit, remains open well beyond depths tested to date. Positive results from deeper drilling across the deposit highlight strong potential for extensions at depth, below the currently defined mineral reserves and resources (Figure 4).
