RTG JOINS LANDOWNER BACKED CONSORTIUM PROPOSAL IN RESPECT OF THE

COPPER-GOLD PANGUNA PROJECT IN BOUGAINVILLE

ANNOUNCEMENT TO THE AUSTRALIAN SECURITIES EXCHANGE AND TORONTO

STOCK EXCHANGE

26 JUNE 2017

RTG Mining Inc. ( ASX:RTG, TSX:RTG ) (“RTG” or “the Company”) confirms recent press

statements that it has been nominated as the development partne r with the joint venture

company of the Special Mining Lease Osikaiyang Landowners Assoc iation (“SMLOLA”) and

Central Exploration Pty Ltd (“Central”) in their proposal with respect to the redevelopment of

the 1.5B tonnei Copper-Gold Panguna Project located in the Central Region of t he island of

Bougainville, within the Autonomous Region of Bougainville, Pap ua New Guinea (“PNG”).

RTG has subscribed US$0.75M into Central for a minority positio n in Central.ii The proposal

being led by the SMLOLA is a landowner initiative and will be s ubject to the success or

otherwise of the SMLOLA in securing a role in the redevelopment of the mine.

This proposal is also, ultimately conditional upon the support of the Autonomous Bougainville

Government (“ABG”) and others. RTG appreciates the trust and su pport the SMLOLA has

shown the Company, recognising the community engagement track r ecord and the

development experience of the RTG management team, having successfully developed seven

new mines in five different countries. RTG makes no representat ion that the SMLOLA led

consortium proposal will be successful. Both the show cause no tice issued by the ABG to

Bougainville Copper Limited (“BCL”) in connection with the previous exploration permit, which

expired in September 2016 and the application for extension of the term of the licence are still

under review by the ABG. The ABG has expressed its support for BCL

The members of the SMLOLA are the owners of the customary land which is the subject of

the old BCL operated Panguna open pit mine area. In implementi ng the Bougainville Peace

Agreement, a change in the mining law in 2014 resulted in the P NG ownership of mineral

rights being expunged and the customary landowners becoming owners of the minerals within

their land. Accordingly, the SMLOLA own the minerals of the ol d Panguna Mine and are in

control of access to their land, namely the Panguna pit. The S MLOLA has stated that it will

not grant access to their lands to BCL, a position they have he ld and expressed for an

extended period of time. The Autonomous Region of Bougainville has gone through

transformative changes over the last couple of years and has recognised the reopening of the

Panguna Mine is an important economic initiative for all Bougai nvilleans, which is supported

strongly by the SMLOLA.

RTG will fully respect any rights of BCL and has agreed to act as the development partner

should the SMLOLA be successful in their proposal. RTG believe s that the SMLOLA led

consortium could provide a constructive and valuable contributi on to resolving outstanding

issues between all parties, with their proposal including the d evelopment of Panguna on a

staged basis, starting at an initial targeted 15Mtpa plant size before then optimising the

processing plant, subject to completion of a Feasiblity Study. This will enhance the prospects

of a successful referendum on Independence for Bougainville and much earlier access to

financial rewards for all Bougainvilleans. There are strong parallels between this proposal and

the redevelopment of the Masbate Gold Mine in the Phillipines, which was successfully

developed by the RTG Management team. The proposal also includ es a Bougainville

Redevelopment Fund to assist the landowners and ABG in implementing much needed social

and infrastructure programs to enhance the livelihoods of all those in and around Panguna.

RTG’s three largest long term shareholders, whose publicly repo rted parent company net

worth is in the order of US$30 billion, have expressed support for entering into the Panguna

redevelopment proposal should it be successful.
