PPM Resamples Drill Hole KUD007 for Native Copper Analysis at Kuliuta Copper-Gold Prospect

PAPUAN PRECIOUS METALS CORP ("PPM or the "Company") (TSX VENTURE:PAU)(OTCQX:PAUFF) announces that the Company is resampling and reassaying core from hole KUD007 for further analysis to determine reliable assay results for drill holes completed at the Company's Kuliuta copper-gold prospect. PPM earlier announced drilling a sequence of high-level intrusives and volcanic rocks at the Kuliuta copper-gold prospect containing hypogene (or primary) native copper varying from trace to locally high (visual estimates) concentrations as millimeter-thick void and fracture fillings over long intervals in holes KUD007, KUD008, KUD009 and KUD010 (see PPM news releases dated August 2nd, August 17th and September 23rd, 2011).

Drill core has been continuously sampled at either 1.0m or 2.0m intercepts throughout the mineralized interval, for all holes completed in this program. Drill core is then halved by sawing on site. One-half of the core is forwarded to the laboratory for analysis, with the remaining core stored in coretrays on-site. Conventional sample preparation of drill core taken from within the hypogene native copper zone (hole KUD007 from 112m - 273m down-hole) using crushing and pulverizing has not provided reliable analytical results. The preparation and analysis of samples containing native copper has proven difficult due to the copper being a malleable metallic substance that is prone to smearing on both crushing and pulverising surfaces during preparation. The apparent loss of copper from samples is clearly evident in samples where native copper was observed to be abundant. For example, in the 123.8m interval in Hole KUD007 (see photo http://www.ppmpng.com/KUD007_123.8m.jpg), where native copper concentration was visually estimated at greater than 1% Cu, standard sample preparation using a preliminary jaw crush and pulverising and analysis using aqua regia digest and inductively coupled plasma optical (atomic) emission spectrometry were unable to verify the estimated copper content. A 1m assay including this interval returned an anomalous and surprisingly low result of 632ppm Cu.

The extreme variability in abundance/mode of occurrence of native copper at Kuliuta creates an additional layer of complexity in formulating an individualized specific programme of sample preparation. Solutions to sample preparation issues are case-specific, and seem to be dependent upon the abundance of native copper in the sample.

PPM re-sampled the interval 112m to 316.60m in hole KUD007 by splitting one-half of the remaining core from the interval containing visible native and sulphide copper. This drill core sample is now in Port Moresby en-route to accredited laboratory ALS-Chemex, Brisbane. The Company remains confident that a solution will be found for determining reliable native copper content in drill holes at Kuliuta.

Further updates will be provided when available.
