Step-out drilling at O’Brien intersects 92.89 g/t Au over 2.60 m,

47.10 g/t Au over 2.50 m and 45.33 g/t Au over 2.20 m

highlighting lateral expansion of the first mineralized trend

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 60,000 m exploration drill program at its O’Brien gold project located along the

Larder-Lake-Cadillac Break, halfway between Rouyn -Noranda and Val -d’Or in Quebec,

Canada.

Highlights

Shallow high-grade intercepts suggest an opportunity to expand resources in the

gap between the old O’Brien mine and the upper part of the first high-grade trend

• Hole OB -20-153 intersected multiple mineralized intercepts outside defined

resources approximately halfway between the first mineralized trend and the old

O’Brien Mine, including;

o 92.89 g/t Au over 2.60 m (vertical depth of 230 m);

o 47.10 g/t over 2.50 m (vertical depth of 150 m),

o Both intercepts were obtained outside current resources west of the first

mineralized trend along with visible gold showings

• These intercepts were obtained above and to the east/west of historical high-grade

intercepts of 43.37 g/t Au over 1.31 m and 124.57 g/t over 0.82 m, all of which are

currently excluded from the 2019 resource estimate

• Assays are pending for hole OB-20-168 which intersected visible gold in two

sections, 295 m and 330 m respectively below hole OB-20-153 and west of

current resources (See Visible Gold in hole OB-20-168 and OB-20-153)

• OB-20-153 along with previously released and historical high-grade intercepts

highlights an opportunity for significant resource growth in gap between the old

O’Brien mine and currently defined resources in the first mineralized trend.

Deeper drilling highlights potential for resource growth in the first mineralized trend

both to the east and west, below the boundary of currently defined resources

• Hole OB-20-148W1 returned 45.33 g/t Au over 2.20 m core length (vertical

depth of 700 m) immediately below and at western boundary of current resources

within the first mineralized trend.

o The intercept was obtained more than 125 m west of other high-grade

intercepts including 16.76 g/t over 4.00 m, 37.76 g/t over 2.00 m and

66.71 g/t over 4.70 m.

o In addition, OB-20-148 intersected 5.47 g/t over 2.00 m, approximately

150 m below OB-20-148W1.

o Results highlight the potential to expand mineralization to the west

towards the old O’Brien Mine

• Assays are also pending for OB-20-164, OB-20-167 and OB-20-170, all of which

intersected visible gold in mineralized structures, close to historical intercepts of

1920.00 g/t Au over 0.21 m and 101.31 g/t over 0.61 m outside current

resources on the eastern portion of the first mineralized trend.

• Current resources in the area are limited to a vertical depth of 600 m and drilling

to date has demonstrated continuity down a depth of approximately 950 m

o Within an area extending approximately 300 m laterally and 350 m

vertically below the resource boundary.

o Mineralization is open for expansion laterally and at depth below 950 m.

Drilling at O’Brien continues to validate 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.

• 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)

• Latest results demonstrate lateral expansion of first mineralized trend to the east

and west. Results so far have traced mineralization in the first high -grade trend

down to 950 m (approximately 350 m below the resource boundary). Mineralization

remains open for expansion at depth as well as laterally to the east and west.

• 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 Radisson controls

along the Cadillac Break.

52,500 m of drilling completed to date with assays pending for approx. 16,500 m

• This release represents approximately 2,729 m of drilling.

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

represent only 60% of the total planned 60,000 m program.

• The company is funded to expand the program to over 75,000 m.

“We are very pleased with results from our ongoing drill program that continue to validate

our litho-structural model and highlight the significant resource upside at O’Brien. The

team has continued to do a commendable job with targeting efforts. With results released

so far representing only 60% of our allocated program we look forward to regular

exploration updates over the balance of 2020 and into 2021. ” commented Mario

Bouchard, Chief Executive Officer

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. To the

extent possible, 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.

QA/QC

All drill cores in this campaign are NQ in size. Assays 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 ALS Laboratory Ltd, in Val -

d’Or, Quebec. Samples yielding a grade higher than 5 g/t Au were analyzed a second time

by fire assay with gravimetric finish at the same laborat ory. 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.
