Underground Sampling At The Trixie, Tintic Project

MONTREAL - Osisko Development Corporation report on the ongoing underground exploration program at the Trixie test mine within the Tintic Project, located in the historic East Tintic Mining District in central Utah. Assay highlights include 265 chip samples from 55 mine faces at Trixie.

Chris Lodder, President, said, "The Trixie underground sampling results continue to demonstrate continuity of high grades associated with the T2 structure with many samples returning over 100 g/t gold. The recent exploration cross cuts exploring the T4 structure parallel to the T2 have identified considerable mineralization to the east up to approximately 80 feet wide. Similar high-grade gold telluride mineralization is also identified in the T4. Given these structures are open along strike and down dip, we anticipate advancing our exploration efforts to these areas rapidly with four drill rigs and ongoing advancement of the Trixie decline."
