Papuan Precious Metals (PPM) has started a drill program at its Doriri Creek nickel-palladium-platinum prospect within the Mt Suckling site in Papua New Guinea’s central ranges. The program is aimed at testing the nickel mineralogy at the site which is accompanied by high concentrations of phosphorus minerals, palladium and platinum.
Doriri Creek contains the highest platinum metal grades known in Papua New Guinea. Its lode has a strike length in excess of 520 metres and an average width of 10-15 metres.
The 316sqkm Mt Suckling project is in one of the world’s premier porphyry copper and precious metals belts. It comprises the Urua, Araboro, Loleu, Dimidi and Doriri Creek prospects.
In February, PPM intersected 70 metres @ 0.1% copper and 6.65 metres @ 0.77% copper and 1.84 grams/tonne gold at the flagship Urua Creek prospect. At the same time, significant copper and gold results from outcrop samples at its Metewoi River prospect opened up exploration potential for high-sulphidation epithermal gold and porphyry copper-gold mineralization. Metewoi is 3-4km southeast of the Kuliuta copper-gold prospect within the New Hanover project.
Drilling at Kuliuta has attracted industry interest for its unusual intersection of a native and sulphide copper-bearing sub-volcanic hosted porphyry to depths of about 500 metres below La’mau’sing Mountain.
Final results from the reassaying of the 11 Kuliuta drill holes completed in October 2011 were announced by PPM in February. Highlights of the results include 1 metre @ 0.93% copper 0.47 grams/tonne gold, and 2 metres @ 0.12% copper and 0.76 grams/tonne gold.
PPM’s president David Lindley says, “Our geological team remains optimistic that potential porphyry mineralization exists in the area of the La’mau’sing copper zone as indicated by disseminated and fracture controlled native and sulphide copper found in the drill core.”
He says New Hanover is an outstanding opportunity for the discovery of Lihir-style gold mineralization in a geological terrain bypassed by modern mineral exploration over the last two decades. “The project comprises two separate exploration licences at the north-western end of the alkaline volcanic belt which hosts the giant Lihir and Simberi gold deposits.”
The porphyry copper potential of New Hanover was unrecognized by previous explorers, however drilling at Kuliuta has now confirmed its porphyry potential. The company intends to advance both prospects during 2012.
