Radisson Mining Reports High-Grade Nickel/Copper Assays on its RM Nickel Project

ROUYN-NORANDA, QUEBEC--(Marketwire - Dec. 13, 2007) - Radisson Mining Resources (TSX VENTURE:RDS) is most pleased to report that, as of December 11, 2007, preliminary assay results have been received for 12 drill holes of the Company's 16 hole drill program on the RM Nickel property consisting of 48 claims covering an area of 1304.5 hectares located in Beauchastel Township, Quebec, 20 km west of Rouyn-Noranda. Completion of this drill program was announced in the Company's news release of November 29, 2007. The following details of these 12 drill holes are preliminary results, only, as results for all holes have not yet been received. Also, assays for platinum and palladium have yet to be received. The assaying of split core is carried out at Techni-Lab Laboratories, Sainte-Germaine-Boule, Quebec.

Mr. Dale M. Hendrick, P.Eng., Chairman of the Board and Technical Consultant to Radisson Mining, stated that the initial, high-grade, nickel/copper holes for which assays have been received are " extremely positive", particularly holes #07-01 of 10.9 ft. true thickness averaging 4.31% nickel ("NI") and 4.89% copper ("Cu"), #07-04 of 19.0 ft. true thickness averaging 4.56% Ni and 2.97% Cu, #07-05 of 15.1 ft. true thickness averaging 14.57% Ni and 2.66% Cu, # 07-06 of 18.8 ft. true thickness averaging 3.75% Ni and 2.45% Cu, #07-13 of 11.3 ft. true thickness averaging 5.98% Ni and 1.43% Cu and #07-16 of 17.8 ft. true thickness averaging 2.65% Ni and 3.23% Cu. Here are the initial assay results.

These holes were vertically drilled within an approximate area measuring 40 feet by 50 feet at 15 foot grid centers.

The diamond drilling program is part of a confirmatory due diligence study on the RM Nickel property being carried out through testing both high-grade and low-grade mineralization zones in an overall area of 125 feet north-south and 50 feet east-west. The next step, after receipt of all assay results, will be preparation of the material to be sent for metallurgical testing at the SGS Laboratory at Lakefield, Ontario.

In 1980, Falconbridge Copper estimated the resources of the RM Nickel deposit at 131,352 metric tons grading 0.46% Ni and 0.79% Cu. This calculation was based on the results of more than 100 holes drilled by the RM Nickel company in the late fifties.

In August 2000, a feasibility study carried out by Dasserat Resources Inc. indicated an open-pit mineable resource of 6,366 metric tons at 2.180% Ni, and 2.353% Cu, plus 3.571 g/t palladium and 1.310 g/t platinum. The foregoing are considered historical resources. The current work program is intended to establish valid current mineral resources.
