Abstract The Frieda River project in the Sepik River area of Papua New Guinea, is host to a Cu-Au mineralized system that represents a classic example of the spatial juxtaposition of porphyry Cu-Au and high sulphidation Cu-Au environments. The deposits are hosted by the Frieda River volcano-plutonic complex described as a stratovolcano composed of a lower sedimentary sequence overlain by an andesitic volcanic edifice. The porphyry deposits, including Horse-Ivaal-Trukai, are closely associated with porphyritic intrusive phases that intrude the lower part of the sequence and the Cu-Au mineralization is strongly controlled by northwest trending structures. The porphyries outcrop at lower elevations in the southeast part of the property but the hosting structures extend into the volcanic succession to the northwest and at higher elevations they correspond to zones of advanced argillic alteration that host the Nena High-sulphidation deposit.

Recent exploration drilling on the property has resulted in significant expansion of the resources of both the porphyry and high sulphidation deposits and the presentation will focus on the new resources estimates and discovery of mineralization that is considered to be transitional between the two deposit types.
