PNG Gold Corporation Provides Corporate Update

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 14, 2011) -

NOT FOR DISTRIBUTION IN THE UNITED STATES OR TO U.S. NEWSWIRE SERVICES

PNG Gold Corporation ("PNG Gold" or the "Company") (TSX VENTURE:PGK) is pleased to outline its exploration, development and financing plans for the Imwauna project, Normanby Island, Milne Bay Province, Papua New Guinea.

Imwauna Property Description

The Imwauna gold property is located off the eastern tip of Papua New Guinea on Normanby Island (Figure 1 – attached site map, showing Normanby Island relative to Papua New Guinea and Australia: http://media3.marketwire.com/docs/p613a.JPG). The property contains numerous vein systems that outcrop at surface. The main vein system discovered to date – the Imwauna vein system - hosts high grade, low sulphidation, near-surface epithermal gold-silver mineralization. The Imwauna deposit has an excellent location as it is only 4 km from the coast at an elevation of approximately 400 m asl. (Figure 2 - See map attached: http://media3.marketwire.com/docs/p613b.JPG). As well, the island is only 65 km northeast of the city of Alotau on the mainland of Papua New Guinea which provides excellent support infrastructure to the project.

With several drill hole intersections exceeding 10 g/t Au over 1.0 m (over 20% of the 178 drill holes have intersections over 10 g/t), management believes the Imwauna deposit has the potential to become a high grade gold mine - see Highlights in Table 1 below. For full drill results see Tables 1, 4, 5, 5A and 5B in the Technical Report filed on SEDAR on December 17, 2010 on behalf of International Silver Ridge Inc. (the "Technical Report"). The deposit has been delineated by surface trenching over more than 1,000 m of strike length and drilled to an average depth of 100 m vertically from surface. It is open at depth and on strike, particularly to the south where the limited previous drilling demonstrates the continuation of the vein system. The veins dip steeply west and range in width from less than 1 m up to 10 m. Gold occurs as free gold and in electrum. The property hosts numerous other mineralized veins that have been mapped in outcrops at surface but have received minimal previous exploration and little or no drilling.

Please note the above results are highlights, and should not be taken to represent average or median results. For full drill hole results, please see the Technical Report.

Exploration

Exploration drilling re-commenced in January, 2011 and is anticipated to continue throughout the year. The current phase of drilling (phase I) is designed to provide in-fill drilling on the deposit as well as test the extension of the known mineralization below 100 m from surface. At the end of May, approximately 50% of the 6,500 m program has been completed. Initial assay results are awaited. Currently, two core drills (HQ) are in operation on site. Phase II will commence immediately after phase I and will test the extensions of the known mineralization along strike, as well as conducting further infill drilling and continuing to explore at depth.

The exploration camp has been expanded and a program to further enlarge and upgrade the accommodation facilities is under-way. The current crew at site stands at 60 and comprises over 90% PNG nationals. As well, an expediting office has been set-up in Alotau on the mainland to support the Imwauna operations.

Underground Exploration Programme

A comprehensive underground exploration programme is to be initiated to confirm the grade, continuity and mineability of the Imwauna deposit. The underground program will allow for test mining of the vein between two levels and set up drill stations in hanging wall drifts for definition drilling of the deposit. It is also planned to extract a 5,000 tonne bulk sample for metallurgical testing.

The programme is designed to take advantage of one of the significant advantages of the Imwauna deposit – that of excellent access to the vein system. Favourable topography, coupled with the sub-vertical nature of the Imwauna veins, enable the Company to access the deposit by short, horizontal adits, 100m or less in length. In addition, the geology at site is not particularly complex and unlike some other epithermal deposits, the Imwauna vein system does not sit on any major fault lines. As such, ground conditions are expected to be competent.

The Company intends to complete 950 metres of drift development for the underground exploration program. As well, 14 cross-cuts and drill cut-outs are scheduled to be completed. Two levels will be accessed – the 390 level and the 420 level (asl). There are 80 metres of development to the vein at the 390 level and 45 metres to the vein at the 420 level. (Figures 3 A&B - see plans attached for further details: http://media3.marketwire.com/docs/p613c.JPG; http://media3.marketwire.com/docs/p613d.JPG). The Company has circulated a Request for Proposals to three mining contractors with experience in the region and will be commencing work once a contractor has been selected and the program is permitted.

In carrying out this programme the Company intends to develop the underground workings to allow for fast-track development of a mine, if warranted. The underground exploration work is therefore designed to create openings and associated underground infrastructure that can be incorporated in any subsequent production plan. Consequently all access adits, development drifts and cross-cuts will have dimensions of 4 metres by 5 metres.

Project Scope

Management's intention is to rapidly advance the Imwauna property to a production decision. The deposit is high-grade, near surface and close to the coast. The terrain surrounding the property is quite favourable to mine and mill development. Access to support infrastructure in the city of Alotau also enhances the site development potential at Imwauna. A 1,200 tpd production rate utilizing a conventional gold leach mill design has been selected by management to form the basis of a pre-feasibility study which has recently been initiated (Fig. 4 – see attached Pre-Feasibility Study Scope for details: http://media3.marketwire.com/docs/PGKFigure4.jpg).

Engineering and Design

The project team is led by Colin McKenzie, P.Geo and COO for PNG Gold. The following consultants have been engaged to carry out the pre-feasibility study and initial design work;

The anticipated cost of the study is $2.0 million and it is scheduled to be completed by May 2012, at which time the Board of Directors will make a decision whether or not to go into production at the Imwauna property.

Immediate Work Plan

PNG Gold's CEO, Mr. Dick Whittington, formerly the President & CEO of Farallon Mining Ltd, brought Farallon's G-9 Mine into commercial production in less than four years from an initial, blind, "greenfield" discovery by utilizing a "Parallel Track" approach. This model simultaneously completed a variety of tasks, normally carried out in sequence, to bring the mine into early production. A similar model will be advanced on the Imwauna project. Management's immediate operational strategy consists of two components, namely:

1. Adding resources through a vigorous exploration programme and,
2. Quickly advancing Imwauna toward a production decision.

(Figure 5 - see timetable attached: http://media3.marketwire.com/docs/p613f.JPG)

Dick Whittington commented, "We are currently following the 'Parallel Track' model which I successfully used at Farallon's G-9 Mine in Mexico. The Imwauna project has similar features to the G-9 Mine that allow for this type of fast-track development. We are very keen to make a production decision for a mine at Imwauna at the earliest opportunity. We are also looking forward to enabling the creation of sustainable community capacity and socio-economic developments on Normanby Island and in the Milne Bay region."

Financing

To fund the above mentioned corporate activities, PNG has entered into an engagement letter dated June 9th, 2011 with Canaccord Genuity Corp. ("Canaccord Genuity") whereby Canaccord Genuity and Paradigm Capital Inc. (the "Agents") will act as co-lead agents with respect to a private placement on a "reasonable commercial efforts" basis to raise aggregate gross proceeds of approximately $35,000,000 on terms to be determined in the context of the market. The Agents will have the option to offer up to an additional 15% of the offered securities at the same price and terms as the Offering to cover over-allotments. Canaccord will also act as sole book-runner. As consideration for their services, the Agents will receive a commission equal to 6% of the gross proceeds in cash, and be issued warrants ("Broker Warrants") exercisable at the offering price to purchase a number of common shares equal to 6% of the shares sold under the Offering. The Broker Warrants will be exercisable for up to 18 months from the closing date. Shares issued under the Offering, and on exercise of the Broker Warrants, will be subject to a hold period of four months from the closing date. The Offering is expected to close on or around July 7th, 2011, subject to acceptance by the TSX Venture Exchange and receipt of any required regulatory approvals.
