PNG Gold Corporation ("PNG Gold" or the "Company") (TSX VENTURE:PGK) is pleased
to report assay results from its 2011 exploration program at the Imwauna gold
project, located on Normanby Island, Milne Bay province, eastern Papua New
Guinea.
Highlights:

(m) (m) (m) g/tonne
IMH253 134.9 139.9 3.0 21.70
147.9 153.9 6.0 112

including 149.9 150.9 1.0 327
Points of Interest:
-- Geological mapping of the Imwauna vein system has extended the system
over 2.0 kilometres along strike and remains open.
-- Drilling has extended the zone to over 150 metres in depth and remains
open.
-- Geological setting is an epithermal, low-sulphidation quartz vein
system.
-- 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 percent fine pyrite. Vein margins are often brecciated and
resealed with silica.
-- Many vein systems on Imwauna including Kela's remain untested.
-- Based on results to date and the vein system's potential, PNG Gold is
planning an aggressive drill program.
A summary of the gold mineralized zones from the four drill holes is presented
in Table 1. As with previous results, only minor amounts of sulphides are
present and no visible gold has been reported even from the very high grade
samples.

Core lengths are not true thicknesses, which have yet to be determined.
(i) Hole IMH237 sample interval 149.6-150.40 metre has no assay result and
is given a value of zero.
The highlight from these holes is a very high grade section of 112 g/tonne Au
over 6.0 metres in hole IMH 253 which includes 4.0 metres zone grading 162
g/tonne Au and a 1.0 metre zone grading 327 g/tonne Au. This section confirms
the high grades returned from IMH 237 which averaged 28.72 g/tonne Au over a
20.2 metre wide zone with multiple quartz veins.
The three additional holes on Section 10200 were drilled to produce better
samples from this part of the deposit and to delineate the continuity of the
high grade material indicated by the initial results from IMH 237. It was felt
these results needed to be repeated due to the broken, rubbly nature of the core
and poor recoveries throughout the zone of veining.
IMH 248 was designed to undercut the veins intersected in IMH 237 while IMH 249
and IMH 253 were drilled to twin the IMH 237 section. IMH 248 intersected a 7.5
metre wide zone of quartz veining, silicification and altered wallrocks but did
not repeat the high values encountered in IMH 237. Drill hole IMH 249, drilled
6.5 metres away in an initial attempt to reproduce the grades intersected in
IMH237, also returned very modest values indicating that the zone is
characterized by high local variation in grade and typical pinch and swell
characteristics. Nevertheless, the second twin hole, IMH 253, confirmed and
enhanced the high grade results seen in IMH 237 with zones of 3.0 metre grading
21.69 g/tonne Au and 10 metre farther down the hole a second zone of 6.0 metre
grading 112 g/tonne Au.
Further closely-spaced drilling will be required to fully delineate the
orientation of any high grade zones within the deposit and assess the potential
for extensions or repetitions either along strike or at depth.
Table 2 lists assay results recently received of resampled 1/4 split samples
from previously published diamond drill holes. The program was undertaken to
check results published in the company's February 09 and February 29, 2012 news
releases.

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. Samples grading over 100 ppm Au are subjected to a
fire assay with gravimetric 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 licence -- EL 1091 -- is located on the north side of
Normanby Island, approximately 80 kilometres 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.
Historic exploration drilling has outlined gold mineralization over a strike
length of at least 900 metres to an average vertical depth of about 100 metres.
Widths range from 0.5 metre to 6.0 metres in the Main Vein. Recent drilling had
confirmed the extension of the Imwauna vein system to depths of 150 metres, with
high-grade intercepts evident at this depth. Drilling is continuing, and is
designed to extend the deposit to depth and along strike.
About PNG Gold Corporation

program in Papua New Guinea. PNG Gold holds a 100% interest in the Imwauna and
Sehulea properties on Normanby Island, Milne Bay Province, Papua New Guinea, and
