Radisson Initiates Induced Polarization Survey on the Douay Property

ROUYN-NORANDA, QUEBEC--(Marketwired - Aug. 15, 2017) - Radisson Mining Resources Inc. (TSX VENTURE:RDS)(OTC:RMRDF) ("Radisson" or the "Company") is pleased to announce that it has initiated a 42 km Induced Polarization (IP) geophysical survey on it's 100% owned Douay property. The property is located in the Eeyou Istchee James Bay territory, approximately 215 km north of Val-d'Or, Quebec and accessible via Provincial Highway 109. Located in the north-central part of the Abitibi Greenstone Belt along the Casa-Berardi-Cameron Deformation Zone, the property consists of a 16 km² land package bordered to the west, east and south by Aurvista Gold Corporation's Douay Gold Project (See figure 1) (TSX VENTURE:AVA)(OTCQB:ARVSF) ("Aurvista").

Radisson owns 100% of the Douay property, free of any royalty, options or outstanding agreements and has excess work credits in the amount of $ 546,216.

First phase of work

Of late, the Douay area has witnessed intensified staking activity and attracted investor interest due to increasing exploration activities in the area. The Company's first phase of work included a geoscientific compilation of all exploration work completed on and nearby the Douay property. This work has included compilation and interpretation of geological structural, geochemical and geophysical data on a regional scale. In addition, the Company has compiled all historic diamond drilling, EM (Input) geophysical anomalies and data from an IP survey (GM 52723, Jonpol project) completed on and immediately adjacent to the Douay property. A total of 108 historical drill holes drilled in the area have been compiled to better define the mineralized zones. This includes 12,980 meters of drilling completed between 1982 and 1987 on 55 drill holes located on the Radisson's Douay property.

Interpretation of the historic data has defined four gold trends and high-priority exploration targets that remain to be tested on the Douay property. The four gold trends are referred to as the Harricana deformation zone, the Douay deformation zone, the Vezza mine gold trend and Northway as depicted on figure 2. These four gold trends have been the focus of historic exploration activity, including drilling programs.

Radisson intends to complete an IP survey to identify new drilling targets on the interpreted Vezza mine gold trend (See figure 2).

O'Brien gold project update

Radisson's focus remains on the O'Brien gold project where the company continues to advance its exploration and development program. To this extent, Radisson has completed 24 drill holes for approximately 11,000 meters of drilling from April to the end of July. This has included 14 drill holes targeting down-dip extensions of the F Zone, 36E and Kewagama mineralized zones with the aim of increasing current resources. In addition, the Company has completed 10 drill holes testing high-priority exploration targets parallel (i.e. to the north and south) and along strike of the O'Brien deposit.
