The Company’s work on the ground comprises early-stage regional stream traverses/mapping and geochemical sampling (stream sediment and rock chip) designed to infill the historic PNG Geological Survey work. Off the back of this work, sites are further upgraded by infill sampling, regional and grid-based soils, and ground geophysics.
2019 saw the Company focus its attention on securing landowner access and prioritising the Fathom Geophysics Priority 1 targets reported in Q1 2019. Peripheral targets at Kunai Hills, Kaskurus, and NW of EL04 were visited and evaluated. The sites are largely characterised by weakly altered volcanics, and no further work is currently planned.
The second half of 2019 saw the Company refine its focus to the “Upper Ramazon Anomalous Zone” (URAZ), the ~20km x 10km geochemical anomaly defined by the PNG Geological Survey (Rogerson 1989). This geochemical anomaly is largely coincident with the deep seated magnetic anomaly defined by Fathom Geophysics (Buckingham 2019), and host to 9 of Fathom’s 12 Priority 1 targets.
Access within the URAZ is difficult, both physically and culturally. The Company has been steadily working with landowners to open up access. Initial geological assessments at Teoveane-Teosiri on the eastern side of the zone has shown epithermal style alteration, and “fertile” fractionation trends, but weak geochemistry. More work is planned to complete our assessment here.
The Aita region exhibits locally extensive low order copper mineralisation within a complex geological setting of overlapping volcanic terranes and alteration styles. More detailed work is warranted here when access is opened further.
Melilup is the Company’s number one target. Access to date has been limited to the northern “tip” of the magnetic anomaly defined by both The Federal Institute for Geosciences and Natural Resources, Federal Republic of Germany, and Fathom (2019) aeromag surveys. Initial work indicates a complex intrusive history, strongly influenced by regional (northerly trending) structures. Copper-gold mineralisation has been discovered and appears to be associated with discrete regional structures. Work is encouraging, but at a very early stage, and requires improved land access.
The remainder of the URAZ still requires access to be negotiated, and initial geological assessment.
