Radisson Provides Update on Exploration Program at O'Brien Gold Project

Radisson Mining Resources Inc. ("Radisson") is pleased to provide an update on the exploration program at it's 100% owned O'Brien gold project located in the heart of the Cadillac mining camp along the Larder-Lake-Cadillac fault in Quebec, Canada.

Since the last update on December 5^th, 2016 (see press release), assay results have been received for three holes.

Highlights:

• Drill hole OB-16-15 intersected 5.0 g/t Au over 6.0 m; this intercept occurs 100 metres up-dip of intercept which ran hole 5.0g/t Au over 5.0 m in hole OB 16-12 and 25 metres west of the currently defined resource envelope of the 36E Area (see figure 1).
   
• Drill hole OB-16-15 also intersected 4.9 g/t Au over 1.5 m in the Cadillac sediments, north of the Cadillac Fault (see figure 2).
   
• Drill hole OB-16-17 intersected 11.5 g/t Au over 0.6 m at a depth of 125 metres in the Pontiac Group sedimentary package south of current mineral resources (see figure 2).

Mario Bouchard, President and CEO commented: "We are very excited with the results obtained in the current exploration program, as we continue to encounter mineralization outside of the existing resource, as for example, in the "F Zone". The synergies derived from the ongoing historical data compilation exercise combined with insights gleaned from the ongoing drilling program will help drive our exploration program. The upside has never looked better on this property which was mined from 1926 to 1957; finding gold in multiple host rock types - to the west, north, and south of the existing resource - is a potential game changer."

Drill program expanded to 20,000 metres

Given the positive results obtained during the 2016-2017 drilling campaign the company has decided to expand the ongoing drilling program to 20,000 m.

One drill rig is currently operating at the O'Brien project and completing step-out and shallow depth extension drilling on the F Zone, 36E and Kewagama areas. The company will mobilize a second drill rig on the property by the end of March. With results obtained in the Pontiac Group and Cadillac Group sediments the expanded drilling program will include shallow depth extension drilling and also exploration drilling on numerous high priority targets generated from our historic data compilation program, "Orevision IP" (induced polarization) survey and the 2016-2017 drilling program.

Geophysics survey and historic data compilation

Earlier in January, the company received results from Abitibi geophysics Inc.'s "Orevision IP" survey completed on the southern portion of the O'Brien property. Multiple high priority targets were defined in the Pontiac Group sediments, south of the current and historical resources. Simultaneously, Radisson is advancing a historic data compilation program at the O'Brien project, which it expects to complete by the end of March. These initiatives will potentially allow the company to identify additional high priority exploration drill targets outside of current resources.

Note; Results are presented as downhole width; true widths are estimated to be between 55 to 70% of downhole thickness.

All drill cores in this campaign are NQ in size. Analyses were completed on sawn half-cores, with the second half kept for future reference. The samples were analyzed using standard fire assay procedures with AA finish at Techni-Lab Actlabs in Ste-Germaine-Boulé in Abitibi, Quebec. Samples yielding a grade higher than 5 g/t were analyzed a second time by fire assay with gravimetric finish at the same laboratory. Samples containing visible gold were analyzed with metallic sieve procedure. Standard reference materials and blank samples were inserted prior to shipment for quality assurance and quality control (QA/QC) program.

Finally, Radisson would like to announce the resignation of Marianna Simeone as a director of the company. Marianna Simeone has been a valuable member of the Board of Directors since 2015. The Company would like to thank Ms. Simeone for her valuable contribution as a director and wishes her well in her future endeavours.
