Osisko Development Corp. announced drilling results from the 200,000-meter 2021 exploration and category conversion drill program campaign at its Cariboo Gold Project (“Cariboo”) in central British Columbia. A total of nine diamond drill rigs are currently active on the project. A total of 120,000 meters have been drilled thus far in 2021. Of that, 42,000 meters have been drilled in the Valley Zone. Recent assay results include holes CM-21-017 to CM-21-029. CM-21-019 intersected multiple mineralized vein corridors including 4.16 g/t Au over 11.85 meters and 8.97 g/t Au over 4.95 meters including a high-grade sample of 41.30 g/t Au over 0.50 meter. CM-21-020 intersected a high-grade vein corridor that assayed 26.58 g/t Au over 5.05 meters including high grade samples of 37.50 g/t Au over 0.90 meter, 58.90 g/t Au over 0.85 meter and 42.80 g/t Au over 1.00 meter. CM-21-024 intersected a vein corridor with visible gold and cosalite and assayed 7.87 g/t Au over 10.25 meters, including a sample of 45.30 g/t Au over 0.85 meter. Detailed drilling results and a drill hole location plan map are presented at the end of this release.
