The material was selected to represent different rock types: semi and massive sulphides, shear zone, diorite dyke and anorthosite. At Corem's facility, each rock type was crushed to less than 1 ½ inches (38 millimeters or mm) and screened at ¾ inch (19 mm). The fractions between 1 ½ inches and ¾ inches of each rock type were blended in different proportion to compose a representative bulk sample prior sorting. An industrial 1 m belt width COMEX OCXR-1000 integrated X-ray and optical sorting system was used and only the dual energy X-ray transmission (DE-XRT) sensor was used for the testing. The ore sorting process helps concentrate the metals of commercial interest, which were principally associated with high density sulphide minerals. During this process, rocks were individually scanned, and low grade (low density) waste material is selectively diverted away from downstream processing.
