Radisson intersects 14.90 g/t over 8.00 m, 41.04 g/t Au over 2.30 m

and 5.73 g/t over 9.20 m highlighting resource expansion potential to

the east and west of the first trend at the O’Brien project

Radisson Mining Resources Inc. (TSX -V: RDS, OTC: RMRDF): (“Radisson” or the

“Company") is pleased to announce significant high -grade gold intercepts from the ongoing

exploration drill program at its 100% owned O’Brien gold project located along the Larder-Lake-

Cadillac Break (see location map 1 and location map 2), halfway between Rouyn-Noranda and

Val-d’Or in Quebec, Canada.

Drilling has continued to validate the 2019 litho-structural model (announced in February 2019)

while demonstrating the potential for resource growth at depth and along strike. Drilling so far

has been focused on an approximately 1 km strike length to the east of the old O’Brien Mine ,

historically considered the highest -grade gold mine in Quebec (production of 587,121 oz Au

grading 15.25 g/t from 1926 – 1957). With the acquisition of the New Alger project (August 2020),

Radisson now controls approximately 5.2 km of highly prospective strike along the Cadillac

Break, including 2.5 km to the east and west of the main shaft at the old O’Brien Mine.

1. VG denotes the presence of visible gold

2. Core length or down hole width. True widths are estimated at 70% to 80% of down hole width. Unless otherwise appropriate

(e.g., proximity to other higher-grade intercepts), primary intercepts reflect minimum mining width (1.5 m true width) consistent

with assumptions used in the 2019 resource estimate.

3. Assay grades shown uncapped. A capping factor of 60 g/t Au was used in the 2019 resource estimate

4. Table includes only intercepts that meet 5 g/t Au cut-off and minimum mining width constraints used in the 2019 MRE. For a

Resource expansion potential to the East of the first mineralized trend (300 m east of the

old O’Brien Mine)

• Hole OB-20-164 returned multiple mineralized intercepts approximately 38 m to the

east of currently modeled resources in the first trend including,

o 41.04 g/t Au over 2.30 m core length (vertical depth of 185 m) including 170.50

g/t over 0.55 m, including visible gold showings and

o additional high-grade intercepts 280 m vertically below the above intercept,

including (see figure 1 for Au grade distribution),

▪ 10.46 g/t over 2.05 m core length including 36.40 g/t over 0.50 m, and

▪ 5.84 g/t over 1.75 m core length including 19.65 g/t over 0.50 m

▪ these intercepts were obtained,

• approximately 150 m vertically above and 50 m to the west of

the previously released intercept of 110.97 g/t over 2.50 m from

hole OB-20-167

• approximately 150 m vertically above and 55 m to the west of a

historical intercept of 1920 g/t over 0.21 m (U-1328)

Figure 1. OB-20-164: Au grade distribution from 493.85 m to 505.00 m

• Hole OB-20-170 returned multiple mineralized intercepts approximately 25 m to the

east of currently modeled resources in the first trend (and approximately 110 m below

and 75 m further east of the high-grade intercepts in OB-20-164) including,

o 8.43 g/t Au over 2.00 m core length (vertical depth of 205 m) including 16.80

g/t over 1.00 m, and

o additional high-grade intercepts 335 m vertically below the above intercept,

including,

▪ 5.27 g/t over 7.40 m core length including 9.83 g/t over 2.00 m,

▪ 4.02 g/t over 2.00 m core length including 6.15 g/t over 1.00 m, and

o 5.73 g/t over 9.20 m core length (vertical depth of 570 m) including,

▪ 13.45 g/t over 1.90 m core length including 25.30 g/t over 1.00 m, and

▪ 12.15 g/t over 2.00 m core length including 23.20 g/t over 1.00 m

• OB-20-164, OB-20-167 and OB-20-170 highlight the potential for resource expansion

to the east of the current resource boundary, between 465 m and 615 m vertical depth.

Resource expansion to the West of the first mineralized trend (300 m east of the old

O’Brien Mine) near the lower boundary of current resources

• Hole OB-20-168 returned 14.90 g/t over 8.00 m (vertical depth of 475 m; see figure 3

for Au grade distribution) approximately 60 m to the West of currently modeled

resources in the first trend. This broader mineralized zone includes,

o 22.24 g/t Au over 2.30 m core length, including 39.00 g/t over 1.30 m,

including visible gold showings, and

o 33.94 g/t over 2.00 m core length, including 67.50 g/t over 1.00 m

• The high-grade intercept was obtained 330 m below previously reported intercept of

92.89 g/t over 2.60 m (from OB-20-153), and approximately 55 m and 145 m,

respectively above historical intercepts of 21.46 g/t over 1.70 m (OB-17-23) and 124.57

g/t over 0.82 m (ST-1029).

• Both intercepts were obtained within multiple mineralized structures appearing to align

with the dip of the first mineralized trend, highlighted by historical drilling and step-out

drilling completed below current resources.

• The high-grade intercepts are both located outside and to the east of the current

resource boundary.

• OB-20-168, OB-20-159, OB-20-158 and OB-20-153 and other historical intercepts

highlight the potential for resource expansion by up to 60 m to the west of the current

resource boundary, starting close to surface down to and 475 m vertical depth.

Figure 3. OB-20-168: Au grade distribution from 583.00 m to 606.00 m

• In addition to hole OB-20-168, hole OB-20-160 and OB-20-163 returned high-grade

intercepts of respectively 7.45 g/t Au over 1.80 m and 5.61 g/t Au over 1.90 m in the

Pontiac sediments suggesting the presence and continuity of ENE mineralized zones

within this geological unit.

Drilling at O’Brien continues to validate the litho-structural model while highlighting

resource growth potential laterally and at depth

• Drilling to date has continued to define and expand three high-grade mineralized trends,

located approximately 300 m, 600 m and 900 m respectively to the east of the old O’Brien

Mine.

• Assays are pending from step-out drill holes completed on all three trends.

• Mineralized trends identified bear similarities with structures previously mined at O’Brien

down to a depth of 1,100 m (historical production of 587 koz grading 15.25 g/t)

• Drilling so far has demonstrated continuity of mineralization well below the boundary of

defined resources in all three trends, which remain open for expansion laterally and at

depth.

o In the first trend, drilling has highlighted continuity of mineralization down to a

vertical depth of 950 m, approximately 350 m below the boundary of resources

that are limited to a vertical depth of 600 m.

o In the second trend, drilling has highlighted continuity of mineralization down to

a vertical depth of 770 m, approximately 300 m below the boundary of resources

that are mostly within 400 m from surface.

o In the third trend, drilling has traced mineralization down to 500 m vertical depth

from surface. Current resources are mostly confined to between surface and 240

m vertical depth.

• Almost all drilling conducted as part of the ongoing campaign has been within a strike

length of approximately 1 km to the east of the old O’Brien mine, representing only a

small portion of more than 5 km of prospective strike that Rad isson controls along the

Cadillac Break.

57,743 m of drilling completed to date with assays pending for approx. 10,790 m

• This release represents approximately 4,979 m of drilling.

• With approximately $15M in treasury, the company is now funded to expand the program

to over 130,000 m through 2021

• Released results to date (since the commencement of drilling in August 2019) represent

only 36% of approximately 130,000 m envisioned to be complete by the end of 2021.
