Mount Fronsac North

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 have 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 Devil’s 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.
