Intercepts From Underground Drilling At Trixie - Tintic Project

MONTREAL - Osisko Development Corp. reported on underground infill and exploration diamond drilling (DD) and chip sampling results from new development areas as part of its ongoing exploration program at the Trixie test mine, within the wider Tintic Project, located in the historic East Tintic Mining District in central Utah.

Chris Lodder, President, said, "The new underground drill results at Trixie have identified several previously unknown mineralized structures that extend existing zones. This enables us to start to plan underground development in those areas for future resource delineation and category conversion. Underground face chip sample results continue to define mineralized zones, namely below the main 625 level, down to and below the 750 level, as well as further to the south of the deposit approaching the Sioux Ajax fault, within our current drill areas."

As most structures at Trixie are steeply dipping to the east or west, current sampling procedures are designed to sample the structure. Chip samples are collected and do not exceed 1.0 m (3 ft.) in length. The face is washed for safety, and for better identification of mineralization, alteration and structures. The hanging wall and footwall of the structures are marked up on the face and back, samples intervals are marked up and follow lithological contacts. Samples are collected in feet and assays are reported in grams per tonne and troy ounce per short ton gold and silver. Conversions to metric and imperial measurements are rounded to two decimal places.
