Rainy Mountain Trenching Program Reveals Two New Zones on Brunswick Property's East Grid

West Vancouver, British Columbia--(Newsfile Corp. - September 12, 2017) - Rainy Mountain Royalty Corp. (TSXV: RMO) (FSE: EK7N) (the "Company" or "Rainy Mountain") announces that it has completed its most recent trenching program on the "East Grid" of its optioned gold exploration property (the "Brunswick Property" or "Property"), which program has revealed two new zones.The Property is located 140 km south of Timmins, Ontario and is accessible year round by bush road connecting to Highway 560 which links to the west with Highway 144 and then north to Timmins (via Highway 101).

East Grid Trenching Highlights:

• 800m extension to west of original gold showing exposed by trench with .388 gm gold (Au) grab sample.
• Strong mineralization exposed on extensions from drill hole BE04.
• Assays of .12 gm gold (Au) in veins with chalcopyrite (copper), 200m west of drill hole BE04 with pathfinder elements detected.

Rainy Mountain has just completed the next phase of trenching and sampling on the East Grid of the Property, which has exposed a strong deformation zone extending from drill hole BE04 (see the Company's news releases of July 12, July 17 and August 28, 2017 for additional details).This zone contains quartz veins up to 1.0m in width that contain chalcopyrite (copper) striking in the same direction as the major shear associated with the 2.1 km long Induced Polarization ("IP") anomaly tested by drill hole BE04. This shear is 400m north of the Ridout Fault and is parallel to that structure. Trenching has exposed this structure from line 50100E to line 49750E at 97+00N (a distance of 350m of mineralization). Assays from grab samples along this structure yielded .12 gm gold (Au) (check assay pending)from both carbonate rock with sulphides and quartz veins with chalcopyrite (Cu). Very anomalous arsenic (As) values, and Vanadium (V), copper (Cu), and antimony (Sb) were associated with this zone. Drill hole BE04 itself contained the highest arsenic value found to date on the Property of 8380 ppm and four very anomalous gold values of .298, .113, .207, and .364 gm gold (Au), attracting the Company's special attention to this zone.

Trenching has also exposed another deformation zone extending west from the original gold showing on line 49800 at 102+50N to line 49000E at 102+25N.Photos of this zone will be posted on the Company website shortly at www.rmroyalty.com, along with a map of the East Grid of the Property showing the IP anomalies, completed drill holes, proposed drill holes and trench locations. Assays of .31 gm gold (Au) (check assay .388 gm Au) were obtained from folded quartz veins in this deformation zone at line 49000, 102+20N, similar to the halo gold values seen at the original showing.Elevated arsenic (As), silver (Ag), and lead (Pb) values were also seen in this zone. Drilling is required to more accurately cross section the geology and to properly sample all the veins in this structure. Soil gold anomalies are associated with this particular deformation zone, which is encouraging the Company to do further drilling along strike.

Additional prospecting and sampling have also been carried out on the West Side of the Brunswick Property and two assays are pending from that area.

Drilling of a series of holes is being planned along strike to drill hole BE04 and the extension of the original gold zone. The Company believes that the trenching to date has been a very valuable tool in exposing the geology of the Property, nonetheless, gaps in exposure may occur which then need to be drilled for even more accurate geological analysis.

Assay Preparation

Assaying was completed by ALS Canada in North Vancouver, British Columbia and sample preparation was done by ALS Canada in Timmins, Ontario. Gold (Au) assays exceeding .2 gm with acid digestion - ICP analysis were then assayed by fire assay on a 30 gm sample and any assays exceeding 3.0 gms were re-assayed by way of fire assay with a 30 gm sample. Pathfinder elements were measured using the ICP acid digestion method on 2 gm samples.

This news release has been reviewed and approved by Robert Middleton, P.Eng., who is acting as the Company's Qualified Person for the Brunswick Property project, in accordance with regulations under NI 43-101.
