Mount Fronsac

The Mount Fronsac deposit contains a historical, non 43-101 compliant, unclassified resource of 1.26 million tonnes grading 7.65 % Zn, 2.18 % Pb, 0.14% Cu, 40.3 g/t Ag, and 0.40 g/t Au. This high grade zone is hosted within 14 million tonnes of low-grade, semi-massive (>60%) to locally massive sulfides that occur in an envelope of quartz-sericite ± chlorite schist.

This high grade deposit has a north-south strike length of 525 metres and a down dip length of 600 metres. Thickness varies from 2 metres up to a maximum of 20 metres. The alteration and disseminated mineralization halo has a maximum thickness of 140 metres and contains up to 50 percent fine- to coarse-grained disseminated pyrite. The pyritic envelope is 900 metres long and extends down dip over 1,000 metres. Massive sulfides are found throughout this alteration envelope, but preferentially occur at or near the upper contact.

Mount Fronsac North was discovered by Noranda in 1999 and is the latest significant massive sulphide body discovered in the Bathurst Camp. It was found by prospecting near a soil geochemical high, indicating that not all the potential in this mature camp is at depth.

Roughly 4 km northwest of Mount Fronsac North lies the Devils Elbow showing. This showing comprises several conformable zones consisting of finely-disseminated to sub-massive sulfides associated with strongly sericitized felsic tuff (footwall) and strongly chloritized quartz-eye tuffaceous sedimentary rocks (hanging wall). The deposit is interpreted to be a Cu-bearing pyrrhotite-pyrite stringer zone situated stratigraphically below a Pb-Zn zone.

These historical estimates were obtained from the New Brunswick Government Mineral Deposits database. Readers are cautioned that Osisko Metals has not completed the work required to independently analyze and verify the results of previous operators nor has a qualified person done sufficient work to classify the historical estimates as current mineral resources or mineral reserves. Osisko Metals is not treating the historical estimate as current mineral resources, and it believes these historical estimates provide an indication of the potential of the property and are reported because they are deemed relevant to the description of the properties.
