Step-out drilling intersects 45.86 g/t Au over 2.10 m, 21.29 g/t
over 2.00 m and 17.90 g/t over 2.15 m in a third potential high
grade trend 900 m east of the old O’Brien Mine
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.
“Drill results from the O’Brien Project continue to validate our litho-structural model and
demonstrate the potential for resource growth at depth and laterally along strike. Prior
drilling demonstrated the potential for two high grade mineralized trends, located
approximately 300 m and 600 m respectively to the east o f and bearing similarities to
structures historically mined at the O’Brien Mine. Our efforts to step-out further to the east
have been rewarded with multiple high-grade intercepts including 45.86 g/t over 2.10 m,
21.29 g/t over 2.00 m and 17.90 g/t over 2.15 m that appear to highlight a third high-
grade mineralised trend in a relatively untested area approximately 900 m to the east of
the old mine. Drilling so far has traced mineralization down to 500 m vertical depth, with
the zone remaining open at depth and laterally.
Our exploration efforts to date have been limited to a strike length of approximately 1 km,
a relatively small part of the 6 km prospective strike length along the prolific Cadillac Break.
While we are impressed by results so far, we are even more excited at the prospect of
leveraging our litho-structural model to target a repeat of our success over a much larger
area that extends ap proximately 3.0 km to the east and now, post the New Alger
acquisition, 3 km to the west of the old O’Brien Mine, historically the highest grade gold
mine in Quebec.
Results released so far represent approximately half of our planned 60,000 m program.
We are well funded to expand our program to up to 75,000 m, permitting additional drilling
into 2021. With three rigs in operation, we eagerly look forward to additional results as we
systematically step out to grow resources laterally and at depth. ” 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

Potential third high-grade mineralized trend (Kewagama area), 900 m east of the
O’Brien Mine
• Hole OB-20-149 returned 45.86 g/t Au over 2.10 m core length (vertical depth of
500 m) with visible gold showing in a smoky quartz vein (see figure 3)
o The intercept was obtained 260 m below defined resources in a sparsely
drilled area 900 m east of the old O’Brien Mine
• Hole OB-20-146 returned multiple high-grade intercepts including:
o 17.90 g/t Au over 2.15 m core length (vertical depth of 105 m) including
28.50 g/t over 1.35 m
o 21.29 g/t Au over 2.00 m core length (vertical depth of 260 m) including
42.40 g/t over 1.00 m
• Hole OB-20-144 returned 5.79 g/t Au over 2.00 m core length (vertical depth of
135 m)
o The intercept was obtained 25 m above defined resources.
• Resources in the area are mostly above 250 m vertical depth. Mineralization is
open for expansion laterally and at depth.

Mine
Figure 4. Visible gold showing in OB-20-149
Results from hole OB -20-144, OB-20-146 and OB-20-149, in conjunction with historical
results, appears to be highlighting a third high-grade steeply dipping mineralized trend
located approximately 900 m to the east of the old O’Brien Mine. Further drilling is planned
to confirm continuity down to 500 m vertical depth (260 m below the limit of resources in
the area) where hole OB-20-149 intersected 45.86 g/t over 2.10 m. Mineralization remains
open for expansion laterally and at depth below 500 m.
Drilling highlights opportunity for resource growth wit hin the second mineralized
trend, 600 m east of the old O’Brien Mine
• Hole OB-20-142 returned multiple high -grade intercepts outside and to the east of
modeled resources in the area, previously highlighted by hole OB-20-124 (See 8.35
g/t Au over 6.00 m) and OB-19-106, these results include:
o 5.58 g/t Au over 2.00 m from 42.00 m core length
o 11.02 g/t Au over 2.00 m from 250.60 m core length
o 5.81 g/t Au over 2.00 m from 282.30 m core length
Results from hole OB-20-142, OB-20-124 and OB-19-106 in conjunction with other recent
results, appears to be defining a second high-grade steeply dipping mineralized trend
starting approximately 300 m east of the high-grade trend defined down to a vertical depth
of 950 m on 36E and F zones. While resources in this area are largely limited to the upper
400 m, results from the ongoi ng campaign indicate a trend that links above high -grade
resources up to 175 m further down plunge. There are indications that the trend could
extend deeper to 1,100 m where a historical intercept returned 17.46 g/t Au over 1.00 m.
Overall results to date suggest strong exploration potential below 400 m for this sector
with assays pending for additional holes in this area.
Drilling continues to expand the first mineralized trend (36E Zone) at depth below
the resource boundary
• Hole OB-20-145 returned 12.48 g/t Au over 2.00 m core length (vertical depth of 725
m)
o The intercept was obtained below the eastern boundary of resources at the
Lower 36E Zone.
o 120 m above a previously released intercept of 66.71 g/t Au over 4.70 m (See
OB-19-92W2b)
o 60 m east of a previously released intercept of 37.76 g/t Au over 2.00 m (See
OB-19-98W2)
Current resources at the 36E zone are limited to 600 m vertical depth. Additional drilling
is planned to establish the resource potential in the Lower 36E area, drilling thus far
suggests strong continuity of mineralization down to 950 m, within an area ex tending
approximately 300 m laterally and 350 m vertically below the resource boundary. This area
remains a key focus for the current drilling program. All holes drilled on Lower 36E as part
of this campaign have intersected mineralization within the targeted geological units, with
most holes returning high-grade intercepts, often accompanied by visible gold showings.
While the majority of drilling so far has been focused on testing the eastern extent of
mineralization at depth, it remains open for expansion laterally (to the east and west) and
at depth below 950 m. Drilling is currently underway to test the western extent of
mineralization, with assays pending for hole OB -20-148W1 having intersected multiple
grains of disseminated visible gold within a smoky quartz vein at the western boundary of
the Lower 36E area.
Exploration program
To this date 45,771 m of drilling have been completed at the O’Brien gold project with
assays pending for approximately 12,771 m. Results released so far represent 55% of the
ongoing 60,000 m drill campaign started in August 2019. The company is funded to
expand the drill program above 75,000 m.
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 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.
