Ongoing Exploration Program At The Trixie Test Mine

MONTREAL - Osisko Development Corp. reported on the 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 of Osisko Development, commented, "The underground face chip sampling at Trixie continues to define mineralized zones, namely below the main 625 level and into the 750 level at Trixie, and further to the south of the deposit closer to the Sioux Ajax fault within our current drill areas. These results will assist in furthering our knowledge of the extents of the deposit and improve our targeting in our underground exploration program at Trixie."

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.

The Trixie test mine is one of several gold and base metal targets within the larger Tintic Project consisting of >17,000 acres of patented mining claims and mineral leases within the historic East Tintic Mining District of Central Utah. The T2 and T4 structures at Trixie show multi-ounce gold grades associated with high sulphidation epithermal mineralization, structurally controlled and hosted within quartzites. The T2 structure mineralization consists of native Au, and rare Au-Ag – rich telluride minerals with quartz. The T4 is a mineralized stockwork zone is located in the hanging wall of the T2 and is comprised of Au-Ag rich mineralization in host rock quartzite with quartz-barite-sulphosalt stockwork veining. Mineralization reports consistent multi-ounce gold grades along the entire strike length.
