The Orient deposit is located 1.3km east of Vomacka pit under cover (Campaspe Formation) and the resource consists of a high grade massive sulphide lens plus a footwall stringer zone.

Orient was drilled out on 20m sections in the upper zone and 40m sections at depth by RGC Thalanga Pty Ltd from 1995-1997 and the current resource based on intersections from 37 diamond drill holes.

Orient hosts a JORC Code (2012) compliant Mineral Resource of 539kt grading 0.9% Cu, 1.8% Pb, 8.0% Zn, 0.2g/t Au and 45g/t Ag. The resource estimate was completed by Mining One Consultants in January 2015.
