As reported previously, the drill hole intersected discontinuous orthomagmatic sulphide mineralization in the basal cumulate sequence of the Seagull Intrusion between approximately 587 and 608 metres. Analysis for platinum group elements (PGEs) was completed using PGM-ICP24 (50 g fire assay with ICP-AES finish), and base metals using ME-ICP61 (four-acid digestion with ICP-AES finish).
