Radisson reports widest and deepest Intercept on the Vintage Zone,

6.9 g/t Gold over 4 meters at 610 meters depth

Rouyn-Noranda, Quebec Radisson Mining Resources Inc. (TSX-V: RDS, OTC: RMRDF)

(“Radisson” or the “Company") is pleased to announce that hole OB-17-49 has successfully

extended the Vintage zone by additional 250 m eters (“m”) at depth at the O’Brien gold project.

The project is located along the Cadillac Break halfway between Rouyn-Noranda and Val-d’Or in

Quebec, Canada. The Vintage zone is parallel to, and to the north of bulk of current resources at

the O’Brien project. The zone is located only 85 meters north of the Cadillac Break in a context

that is similar to producing and historical mines in the Cadillac mining camp.

Press release highlights:

 Hole OB-17-49 extended the Vintage Zone by over 250 meters at depth with multiple gold

intercepts in extension of Hole OB-17-42, which returned 13.7 g/t Au over 1.5 meters.

(See October 3rd, 2017 Press release)

 Significant intersections reported are:

o OB-17-49 with 11.4 g/t Au over 0.5 m at 273.5 m depth

o OB-17-49 with 19.7 g/t Au over 0.5 m at 316 m depth

o OB-17-49 with 8.8 g/t Au over 0.5 m at 379 m depth

o OB-17-49 with 6.9 g/t Au over 4.0 m at 610 m depth within intercept of 2.3 g/t Au

over 16 meters.

(See figure 1 and figure 2)

 The Vintage Zone has been traced over a strike length of 325 meters and vertical depth of

up to 580 meters.

Mario Bouchard, President and CEO commented: “Current exploration results continue to

increase the overall dimension of the Vintage Zone . Vintage remains open in all directions. We

are also encouraged to see that mineralization could also be widening at depth in a Banded Iron

formation encountered at 580 meters depth . Due to its high grade potential and proximity to

current resources, the Vintage Zone has the potential to be an important part of O’Brien’s

exploration and development plan. The team is currently planning a second phase drill program

that could start as early as November on Vintage.”

Vintage zone exploration program

The Vintage zone is a parallel zone of the O’Brien project located approximately 85 meters north

of the Cadillac Break in the Cadillac Group of meta -sediments comprising sequence of

polymictic conglomerate, banded iron formation (BIF) and grauwacke. In comparison, current

resources of 36E and Kewagama zones are located in the Piche Group, south of the Cadillac

Break. The Vintage zone saw small historical exploration programs, which were never followed

upon. In 2017, t he company established several high -priority exploration drill targets through

historical data compilation in this area of the O’Brien gold project. The first seven drill holes that

tested these targets were completed over a strike length of 325 meters and up to 580 meters

depth. The new info added to the few available historical information helps to demonstrate the

continuity and the favourable geometry of the Vintage zone. All intercepts remain open in all

directions.

All drill cores in this campaign are NQ in size. A ssays were completed on sawn half-cores, with

the second half kept for future reference. The samples were analyzed using standard fire assay

procedures with Atomic Absorption ( AA) finish at Swastika Laboratories Ltd, in Swastika ,

Ontario. 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 s ieve procedure. Standard reference materials and blank samples were inserted

prior to shipment for quality assurance and quality control (QA/QC) program.
