PANGUNA LANDOWNER RELEASE ON TITLEHOLDER SUPPORT

ANNOUNCEMENT TO THE TORONTO STOCK EXCHANGE

AND AUSTRALIAN STOCK EXCHANGE

12 JUNE 2018

RTG Mining Inc. (TSX: RTG, ASX: RTG) (“ RTG” or the “ Company”) provides an update

by the Special Mining Lease Osikaiyang Landowners Association Inc. (“SMLOLA”) on

titleholder support in Panguna.

The Chairman of SMLOLA, Mr Philip Miriori released a detailed statement yesterday, 11

June 2018, which comprehensively deals with titleholders support in Panguna.

The full SMLOLA statement is available on RTG’s website.

SMLOLA stated that it has undertaken a substantive awareness program over the last few

months to ensure landowners are fully and accurately informed, to build the unity

requested by President John Momis and provide their SMLOLA community with the

opportunity to express their position.

By way of summary the statement by SMLOLA:

 provides details of the petition provided to titleholders that confirms support for the

SMLOLA consortium to lead the redevelopment of the Panguna mine, as well as

SMLOLA’s existing leadership.

 states that the petition has been signed by 428 titleholders . It notes that of the 510

titleholders list historically prepared and used by Bougainville Copper Limited (“BCL”) ,

approximately 20 titleholders are Bougainvilleans based in Port Moresby or outside

Panguna which the petition process has not yet been able to meet with, therefore after

allowing for those titleholders, SMLOLA has secured almost 90% support level of

titleholders.

 confirms SMLOLA continues to believe that it is the Customary Landowners rather

than the historical “titleholder list” that is relevant under the Bougainville Mining Act ,

however SMLOLA considers the titleholder list provides a comparison basis for recent

landowner support statements by BCL.

RTG recently announced a significant donation for much needed medicines for the new

Arawa Hospital and continues to work on new social programs for the region.
