MR PHILIP MIRIORI CONFIRMED AS CHAIRMAN OF THE SMLOLA WITH

FORMAL RECONCILIATION SIGNED

ANNOUNCEMENT TO THE TORONTO STOCK EXCHANGE

AND AUSTRALIAN STOCK EXCHANGE

5 DECEMBER 2017

The Board of RTG Mining Inc. (“RTG”, “the Company”) (TSX Code: RTG, ASX Code:

RTG) is pleased to announce that Mr Philip Miriori has been confirmed as the Chairman

of the Special Mining Lease Osikaiyang Landowners Association (“SMLOLA”) and all

Court actions will now be withdrawn and come to an end. Mr Miriori has entered into

and signe d a formal written reconciliation agreement with Mr Lawrence Daveona,

following a customary reconciliation process.

Both men have agreed to work together co -operatively, to progress the plans for the

proposed redevelopment of the old 1.5Bt¹ Copper-Gold Project at Panguna . Both the

Chairman and Mr Daveona have also pledged support for RTG as the preferred

development partner. Attached is a copy of the Press Release by the SMLOLA.

This is an historic and important step for the landowners, with RTG being the first mining

company that has been endorsed by the SMLOLA in 30 years. RTG is pleased to have

been afforded the opportunity to play a constructive role in this important reconciliation

process.

As previously announced, the SMLOLA members are the owners of the minerals at the

old Panguna Mine, being the owners of the customary land under which the minerals

lie. The SMLOLA are the only landowner association whose consent is required for the

issue of an exploration licence. The SMLOLA has entered into a joint venture

agreement, under which they have nominated RTG as the preferred developer for any

reopening of the Panguna Mine. Once again, RTG would like to thank the SMLOLA for

the unwavering support they have shown to RTG and we look forward to working with

the team, including Mr Daveona, to progress the Exploration Licence application

currently before the Autonomous Bougainville Government (“ABG”). W e fully

understand and respect the importance of both a social licence and world’s best

practices on all environmental programs and believe that those matters can be handled

sensitively and professionally, so that all Bougainvilleans are both protected and

treated fairly in any redevelopment of Panguna.

As many would be aware, Bougainville Co pper Limited (“BCL”) was the holder of the

previous exploration licence, EL1, which was to expire in September last year, subject

to any valid renewal application by the company. Our legal advice confirms that BCL

does not have a first right of refusal ove r the Project or the grant of an exploration

licence, but it is recognis ed that the ABG must first determine its position on any

apparent renewal application of BCL, before considering the application of the SMLOLA

consortium.

Despite legal advice that the renewal application by BCL did not satisfy the requirements

of the Mining Act, should the ABG choose to continue with the planned Warden’s

Hearing on 11 December 2017, both Mr Miriori and Mr Daveona have indicated they will

recommend strongly to their members to deny their consent. In line with this position,

there has been a petition with 2,000 supporters and at least 112 formal written objections

lodged with the Warden, including one by the SMLOLA setting out extensive conce rns

with any consideration of an extension of BCL’s previous exploration licence. In

Bougainville, a Mining Warden’ s H earing is required in the issue of an exploration

licence to assess whether it has the necessary support of the landowners in the

exploration licence boundary area i.e. the SMLOLA members.

The SMLOLA consortium has been advised that they were the first and to date, only

new application for an exploration licence over the old EL1 ground.

We believe the proposal presented by the SMLOLA consort ium represents a unique

and once in a generational opportunity to responsibly re -open the Panguna Mine for

the benefit of all Bougainvilleans. RTG has always suggested that this is best achieved

by discussion and negotiation with all relevant parties, including the ABG.
