Radisson Mining Announces Broader Scope on the O'Brien-Kewagama Project and Grant of Options

ROUYN-NORANDA, QUEBEC--(Marketwire - Oct. 20, 2010) - Radisson Mining Resources Inc. (TSX VENTURE:RDS) ("Radisson" or the "Company") is pleased to announce an update to its exploration and development activities at its wholly owned O'Brien-Kewagama gold project.

The O'Brien-Kewagama project, located in the Malartic/Cadillac portion of the Abitibi Gold Belt, consists of 24 claims covering 688 hectares straddling the prolific Cadillac Break over a strike length of some 3 km. From 1933 to 1956 the O Brien Gold Mine produced 590,000 ounces of gold from 1.31 million tons of ore at a grade of 0.45 ounces gold per ton, making it the highest grade gold producer in the camp. The mine reached a depth of 3450 feet.

The O'Brien-Kewagama property is located approximately 5 km west of Agnico-Eagle's Lapa gold mine, also centered in the Cadillac Break, and approx 4 km southwest of Agnico-Eagle's Laronde mine, now surpassing 3000 meters (10,000 feet) in depth.

Previous exploration by the company on the project resulted in the new discovery of a resource of 218,540 ounces (indicated resource of 270,000 tons at an uncut grade of 0.56 opt, and inferred resource of 182,000 tons at an uncut grade of 0.37 opt) as defined in the Scott Wilson, Roscoe Postle and Associates NI 43-101 Report of May 2007.

These resources, all outlined above the 650 meter level, are located over 800 meters east of the old O'Brien mine workings, and represent a new discovery of high grade mineralization of the same type mined and produced at the O Brien Gold Mine.

Previous drilling (prev. announced) of these high grade structures of the O Brien type resulted in the discovery of new mineralization and included:

153B 2.3m 13.9 g/t 192m
06-08 2.5m 50.3 g/t 412m
2130-40w 1.8m 41.2 g/t 226m
21-13 7.6m 8.6 g/t 280m
97-87 2.9m 30.5 g/t 314m

During this past year, management undertook a complete re-evaluation and re-interpretation of the project, in the light of the new discoveries and mines in the Abitibi Gold Belt (Osisko, Goldex, Lapa). This work now clearly demonstrates that in addition to the high grade structures and the excellent depth potential of these, there exists other types of gold mineralization on the project, including lower grade, larger width structures, porphyry type of the Osisko and Goldex models, and gold in iron formations.

Previous results from the O Brien-Kewagama project (prev. announced) demonstrate the above and include:

04-08 8.3m 5.4 g/t
08-155A 13.7m 2.4g/t
08-155 5.4m 4.4g/t
97-87 3.2m 4.3g/t

The company is presently planning its diamond drill program on the project, designed to explore for and discover new gold mineralization at the project.
