The MRE contains approximately 12,200 tonnes of copper metal and 13,900 oz of gold. The A-Zone deposit forms part of ERL's Yuinmery Cu-Au project, which also hosts the Just Desserts Cu-Au deposit containing a JORC 2012 inferred resource of 2.52Mt @ 1.31% Cu & 0.49g/t Au.

The A-Zone deposit is a volcanogenic massive sulphide (VMS) Cu-Au deposit hosted by cherts and other exhalatives within a sequence of mafic and felsic volcanics. Empire Resources plans to focus on the shallow (<60m depth) portions of the resources, targeting the high grade supergene zone as well as extensions. The company also has emerging Cu-Au resources at YT01 and Smith Well, and remains enthusiastic about the future for the Yuinmery project as it continues exploring and developing new and exciting opportunities.
