NOT FOR DISTRIBUTION IN THE UNITED STATES OR TO U.S. NEWSWIRE SERVICES
PNG Gold Corporation ("PNG Gold" or the "Company") (TSX VENTURE:PGK) has
received the assay results from the final 12 diamond drill holes completed
during its 2011 exploration program at the Imwauna gold project, located on
Normanby Island, Milne Bay Province, eastern Papua New Guinea. Highlights from
these most recent results include 15.8 g/t Au over 1.8 m in hole IMH 242 at a
vertical depth of 190 metres, the deepest intersection on the property to date,
while hole IMH 245 intersected 16.9 g/t Au over 0.9 m at a shallow depth of 40
metres. Significantly, both holes are in the High Grade zone at the northern end
of the Imwauna vein system.
A summary of the best intersections in this group of drill holes is presented in
Table 1. The drill hole location plan can be viewed at
http://www.pnggold.com/i/maps/Imwauna-Exploration-Locations_27-02.pdf. As with
previous results, only minor amounts of sulphides are present, even in the deep
intersection in IMH 242.

(i) Core lengths are not true thicknesses which have yet to be determined
From the initiation of the program early in 2011, a total of 12,089 metres have
been drilled in 71 drill holes. Drilling continues with two drills being
operated on the property - one of which will be moved to the promising, un-drill
tested, Kela's vein system as soon as possible, while the other will remain on
the Imwauna vein system to further test the deposit's depth and strike extension
potential.
Dick Whittington, President and CEO of PNG Gold Corporation, stated: "These
results open up the Imwauna vein system to new depths. To have grades of 15
grams per tonne at 190 metres vertical depth, along with only minor amounts of
sulphides, is further evidence of the potential of the Imwauna vein system as a
whole. At the same time, these results highlight the potential for high grades
at depth in the high grade zone in the northern section of the deposit.
Following on from the results announced previously on February 9thoutlining a 32
gram per tonne intercept at 160 metres depth in the Southern zone, these results
confirm that the Imwauna vein system has the potential for high grades at depth
along its strike length."
Core logging, sampling and assaying procedures
All holes drilled by PNG Gold are collared using HQ triple tube drill tools. A
few holes have been reduced to NQ size at depth in the hole in order to continue
the hole. Geotechnical measurements such as core recovery, fracturing and
veining, rock quality designations (RQD's), hardness and photographic logging
are performed systematically prior to sampling and assaying. The core is logged,
samples selected by PNG Gold geologists then systematically sawn in half at the
site. The one half core sample is numbered, sealed in a bag and delivered by PNG
Gold to its base in Alotau where the samples are palletized and placed in secure
storage prior shipment to ALS Minerals in Townsville, QLD. The other core half
is retained on the site.
Core samples are dried, crushed and pulverized to 85% passing through a 75
micron mesh. The pulps are assayed for gold and silver using a 50 g split, Fire
Assay (FA) and AA finish. Analyses were also carried out for the trace elements
As and Pb. Results are available on the company's website. Rejects and pulps are
stored at the lab for future reference.
Quality Assurance / Quality control (QA/QC)
The ALS Minerals lab is an ISO 9001:2008 qualified assayer that performs and
makes available internal assaying controls. Duplicates, certified standards and
blanks are systematically used as part of PNG Gold's QA/QC program. The company
also inserts blind standards with each sample batch at the rate of about 1:10.
Periodically duplicate pulps are assayed at a second independent certified assay
lab. The duplicate assays are compared to original assays for reproducibility
and lab bias.

About the Imwauna Gold Deposit
The Imwauna exploration license - EL 1091 - is located on the north side of
Normanby Island approximately 80 km northeast of Alotau, the provincial capital
of Milne Bay Province, eastern Papua New Guinea. Alotau is serviced by daily
flights from Port Moresby the national capital and scheduled coastal freighters.
PNG Gold maintains a logistics base in Alotau to supply the Normanby Island
site.
The Imwauna prospect is an epithermal, low sulphidation quartz vein system
comprising two principal veins, the thicker, more continuous Main vein and the
East vein. The mineralized veins consist of finely crystalline quartz, white to
grey in colour and display typical epithermal textures such as vugs, dog tooth
crystals and fine, chalcedonic layering. Sulphides are rare to absent although
some deeper intersections contain a few per cent of fine pyrite. Vein margins
are often brecciated and re-sealed with silica.
Historic exploration drilling in 178 drill holes (see PNG Gold Corporation
Technical Report, November 30, 2010 on Sedar) has outlined a narrow zone of gold
mineralization over a strike length of at least 900 m to an average vertical
depth of about 100 m. Widths are between 0.5 m to 6 m in the Main vein but less
in the East vein. Prior to this News Release, recent drilling had confirmed the
extension of the Imwauna vein system to depths of 150 metres with high grade
intercepts evident at this depth - see News Release dated February 9th, 2012
reporting 32 g/t over 1.4 m at a depth of 150 metres. Drilling is ongoing and is
designed to extend the deposit to depth and obtain sufficient information to
support a 43-101 resource estimate, now scheduled for the second quarter 2012.
Metallurgical recovery indications on Imwauna are promising with recoveries of
95% Au being indicated from recent test-work with low reagent consumption and
the potential for improvements to these numbers with optimization of leach times
and more controlled crushing and grinding - see New Release dated February 22nd,
2012. Metallurgical testwork is continuing as part of a Preliminary Feasibility
Study planned once the 43-101 resource referred to above is complete.
The Kela's Prospect
Two drills are presently working on the Imwauna project; however, immediately
upon completion of a water project in the Kela's watershed (west draining), one
rig will be deployed to the Kela's prospect to commence a planned 5000 m drill
program. The Kela's vein system is sub-parallel to, and approximately 650 m west
of, the Imwauna deposit and no previous drilling has been done on the prospect.
Kela's exploration to date has been confined to mapping of the vein system and
by numerous trenches along its 1.2 km strike length. Historic results
demonstrated the presence of gold mineralized veins in float and bedrock in the
trenches all within an extensive gold-in-soil anomaly. The Company intends to
fully evaluate the potential of this exciting vein system. Trench assays can be
viewed at: http://www.pnggold.com/i/maps/imwauna_trench_results.jpg.
