ROUYN-NORANDA, QUEBEC--(Marketwired - Feb. 3, 2015) - Radisson Mining Resources Inc. (News - Market indicators) ("Radisson") is continuing its preliminary economic assessment (PEA) of Zone 36 East on the O'Brien property in Cadillac Township, Abitibi, Quebec. As announced in the press release of December 2, 2014, Radisson has incorporated the Kewagama property into this PEA, which should be published in the 2nd quarter of 2015.

In this regard, Radisson would like to draw attention to some results from the 41,000 metres of drilling conducted on Kewagama, which will be integrated into the PEA. Of these 41,000 metres, more than 20,000 metres of historical surface and underground drilling were carried out by Radisson's predecessors from 1932 to 1988. Along with the surface drilling program completed by Radisson from 2003 to 2011, totalling 20,824 metres, this data is currently being compiled and interpreted by firm InnovExplo. Radisson considers it likely that additional interesting intersections will be identified in the historical drilling.

Selected highlights, Radisson drilling programs from 2003 to 2011

Above a vertical depth of 525 m

• 0.30 m at 466.48 g/t Au in hole KW08-157
• 0.30 m at 79.72 g/t Au in hole RM11-05
• 0.40 m at 67.74 g/t Au in hole RM11-02
• 8.17 m at 5.45 g/t Au, including 0.60 m at 49.94 g/t Au in hole KW04-03

At depth, at a vertical depth of 1,150 m

• 1.00 m at 17.46 g/t Au in hole KW04-02W

These results are from various exploration drilling programs on the Kewagama property conducted by Radisson from 2003 to 2011, during which numerous gold intersections were reported. See the table below, "2003-2011 Main Drilling Results", and Radisson's press releases dated September 13, 2004, to April 3, 2012.

The main objectives of Radisson's drilling were to check the mineralization and the geological setting of the gold structures in the area of the old Kewagama mine site, check the potential at a depth of over 1,000 metres on the western edge of this property, and also explore the potential of the area east of the old Kewagama mine infrastructures, where historical drilling had intersected significant gold values in rock of the Piché Group.

President Mario Bouchard commented: "The 43-101 mineral resource estimate for the Kewagama property and its integration into the PEA currently underway on Zone 36 East are logical steps that enhance the economic potential of the project as a whole. The possibility of simultaneously mining Zone 36 East and Kewagama will be considered during this exercise".

The discovery of new, very wide low-grade gold mineralization during work programs in the area east of the infrastructures is also indicative of favourable gold potential. Since the holes are still widely spaced, these intersections remain open and are considered significant exploration targets.

InnovExplo is an independent consulting firm recognized for its expertise in mining geology, exploration, engineering and geomatics. Firm WSP is participating jointly in certain chapters of the PEA, such as ore processing, environmental assessments and studies of some of the infrastructure.
