Osisko Development Corp. (NYSE: ODV, TSXV: ODV) has announced new drilling results from its Cariboo Gold Project in central British Columbia, confirming high-grade gold mineralization at depths exceeding 700 metres in previously untested areas. The results include intercepts of 13.19 g/t gold over 3.60 metres at a vertical depth of 596 metres and 28.90 g/t gold over 0.50 metres at 718 metres vertical depth.
Program Details and Drill Results
The company completed 8,971 metres of surface exploration drilling across 11 diamond drill holes between December 2025 and April 2026. Approximately 65% of the drilling, or 5,823 metres, targeted areas outside the current Cariboo Gold Mineral Resource footprint, which extends to an average depth of about 350 metres. Five drill rigs continue operating, systematically testing targets down-dip of the current resource to a maximum vertical depth of 800 metres.
Select highlight intercepts from outside the current resource footprint include:
- 42.42 g/t Au over 1.50 m in hole IM-26-001 at 111 m vertical depth, including 122.50 g/t Au over 0.50 m
- 6.40 g/t Au over 6.30 m in IM-26-001 at 326 m vertical depth, including 40.60 g/t Au over 0.50 m
- 6.17 g/t Au over 7.10 m in IM-26-003 at 517 m vertical depth, including 73.20 g/t Au over 0.50 m
- 13.19 g/t Au over 3.60 m in IM-26-003 at 596 m vertical depth, including 73.10 g/t Au over 0.50 m
- 28.90 g/t Au over 0.50 m at 718 m vertical depth
Management Commentary
Chris Lodder, President of Osisko Development, stated: “We are encouraged by the initial results of the surface exploration drill program at the Cariboo Gold Project, which intercepted mineralization in all eleven drill holes. Strong high-grade intercepts in previously untested areas and known under-tested gaps continue to demonstrate the at depth potential for resource growth beyond our current mineral inventory. These results reinforce our view that we are only beginning to define the full extent of the mineralized system at depth, while identifying compelling near-mine upside opportunities — all within the Project’s existing permitted footprint. We are at an early stage of this program and are excited to keep drilling.”
Implications for Resource Growth
The results confirm the presence of high-grade mineralization at depth and reinforce the potential for upside in under-tested gap zones and below the current deposit footprint. All 11 drill holes intersected mineralization, with assays received by June 1, 2026. The company is targeting resource growth within the project's existing permitted footprint, which includes permits for mining operations. The ongoing program aims to expand the mineral inventory and define the full extent of the mineralized system.
