The Big Easy prospect is a low-sulfidation epithermal gold occurrence of Neoproterozoic age in the Burin-Bonavista region of Newfoundland, Canada. Mineralization is predominantly hosted in epiclastic rocks of the Musgravetown Group. This well-preserved system lies within the tectonostratigraphic Ava...
