Radisson Mining Resources Inc. Announces the Kewagama Property is Incorporated into the 43-101 Preliminary Economic Assessment of the 36 East Zone
Dec 2 14
Radisson Mining Resources Inc. announced that it expands INNOVEXPLO's mandate with the integration of the Kewagama property into the Preliminary Economic Assessment (PEA) currently underway on the 36 East Zone of the O'Brien property. The possibility of simultaneously mining the 36 East Zone and Kewagama will be considered during this exercise. Over the last few months, Radisson's technical team has compiled more than 41,000 metres of drilling on the Kewagama property, which includes 20,800 metres drilled since 2003 by Radisson. The Company would like to integrate this compilation into the PEA underway. Therefore, INNOVEXPLO will also be commissioned to assess the overall resources of both Kewagama and the 36 East Zone. The comprehensive analysis of these two properties will be standardized for optimal mining of the resource.

Radisson Mining Resources Inc. Announces Metallurgical Tests Performed on Ore from Zone 36 East of O'brien Project
Aug 26 14
Radisson Mining Resources Inc. announced that a series of metallurgical tests performed on ore from Zone 36 East of the O'Brien project has just been completed in the laboratories of the Unité de recherche et de service en technologie minérale de l'Abitibi-Témiscamingue (URSTM) (Abitibi-Témiscamingue mineral technology research and service unit) in Rouyn-Noranda. 11.13 grams per tonne is the average grade obtained from the sample used for testing, Average recovery of 59.2% of the gold contained in the ore by gravity concentration calculated from the twelve (12) gravity concentration tests, Total recovery of 93-94% achieved by combining flotation or cyanidation with gravity concentration. The material used for the metallurgical testing was pulp from Zone 36 East drill core. It consisted of composite core lengths from the main structures of Zone 36 East (structures No. 1-6 and 8). The sample totaled 61 kilograms and had an average grade of 7.26 g/mt (0.212 oz/st) Au. Current NI 43-101 resources, for Zone 36 East are, for the indicated category, 560,000 short tons at a grade of 0.19 oz/st Au or 6.51 g/mt Au. For the inferred category, they are 317,000 oz/st grading 0.21 oz/st Au or 7.19 g/mt Au. Therefore, the grade of the material selected for metallurgical testing was very similar to the grade of the resource categories. However, the average grade of gold recovered from the material tested was 11.13 g/t Au, with variations ranging from 7.47 to 14.59 g/t, which is nearly 56% higher than the grade of the sample prepared for these tests. A first series of tests studied metallurgical recoveries that could be achieved with gravity separation. These tests produced a concentrate grading from 18,158 to 20,968 g/t Au, with recoveries in the order of 50-60% of the gold from the ore. The degree of grinding ranged from 58 to 80% minus 200 mesh; recovery improved as the grind became finer. Subsequently, two processing circuits were considered. First, gravity concentration followed by flotation of the pulp of this concentrate in open and closed circuits. Gravity concentration produced a concentrate grading from 10,263 to 62,143 g/t Au, recovering from 54-67% of the gold from the ore. Flotation produced a concentrate grading 91 to 120 g/t Au. For most of these tests, a total recovery (gravity concentration and flotation) in the order of 93% to 94% was achieved. Some concentrates were analyzed for arsenic, producing results of about 12% As. The second circuit consisted of gravity concentration followed by cyanidation of the pulp of this concentrate. Gravity concentration produced a concentrate grading from 25,598 to 30,508 g/t Au, recovering from 58-60% of the gold from the ore. A total recovery ranging from 90% to 93% was thus obtained. For most tests, the degree of grinding used was 65-66% minus 200 mesh, a grind that is considered fine enough for this type of ore. In addition, reagent consumption, for both flotation and cyanidation, was similar to industry standards.
