Papuan says further analysis required for hole KUD007 at New Hanover

Papuan Precious Metals (CVE:PAU) announced Friday that before final results can be determined, further analysis is required from hole KUD007, which was drilled in the La'mau'sing Mountain zone of its Kuliuta copper-gold prospect, due to a discrepancy between the initial results obtained from the core and the visual estimates of the sample.
The Kuliuta prospect is part of the New Hanover project, which comprises two 100%-owned exploration licenses covering over 591 square kilometres in New Hanover, west of the provincial capital Kavieng in New Ireland Province, Papua New Guinea.
Assays from the hole on the prospect did not co-relate with the visual estimates, the company said, and discussions are now underway with the company's assay laboratory in Australia to determine an alternative method of analysis to ensure reliable and accurate data.
Papuan explained that copper is malleable, and can smear on and adhere to rock crushing and grinding surfaces during the laboratory preparation of samples, resulting in either under- or over-estimation of copper grades, or cross sample contamination.
Analysis for native copper in drill samples forwarded to the lab has therefore proved to be difficult, the company said.
Hole KUD007 was drilled to test a conductivity anomaly that was identified by a 3-D Induced Polarization survey on the property earlier this year.
After further evaluation, it was determined that hole KUD007 intersected a 161 metre wide native copper zone, followed by a deeper 43 metre wide chalcopyrite, or sulphide, zone extending from 273 metres to the end of the hole.
Papuan has commenced a investigation of the copper intersection in hole KUD007 through the drilling of four offset holes. Holes KUD007, KUD008, and KUD009 have been completed, with hole KUD010 in progress.
All four holes have intersected a native copper zone. Hole KUD010 is currently drilling down through the copper-style porphyry mineralization intersected at 273 metres in the initial hole.
The company said it is likely that extensive follow-up drilling may be required to further assess the La'mau'sing copper zone.
