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.
