The drill program will test the nickel mineralogy accompanied by high concentrations of phosphorus minerals like palladium and platinum.
The Mt. Suckling project, which covers two exploration licenses over 316 square kilometres, lies to the eastern end of New Guinea's Central Range, one of the world's premier porphyry copper belts.
It consists of the Urua Creek, Araboro Creek and loleu Creek porphyries and includes the Dimidi Creek potassium anomaly and the Doriri Creek hydrothermal prospect.
Papuan has identified three prospective porphyry prospects in a linear belt some 19 kilometres long and localized within the wide trace of the Keveri Fault Zone, part of the once active plate boundary between the Australian and Pacific plates.
The Doriri Creek hydrothermal prospect is also located in the trace of this structure, about eight kilometres west of the Urua Creek prospect.
In February, the junior mineral explorer unveiled partial results from the uppermost 79 metres of the discovery hole at the Urua Creek prospect.
Among the highlights, hole URD002 hit 70 metres grading 0.10% copper from eight to 78 metres and returned 6.65 metres of 0.77% copper and 1.84 grams per tonne of gold (g/t) from 208.85 metres to 215.5 metres. This includes 1.10 metres of 2.16% copper and 9.60 g/t gold.
Shares of the company went up 5.56 percent Wednesday, climbing to 9.5 cents on Toronto's junior venture exchange.
