Drilling at O’Brien delivers high-grade gold intercepts highlighting
resource growth potential near surface and at depth
3.07 g/t Au over 32.20 m including multiple high-grade intercepts in the Upper 36E Zone
37.76 g/t Au over 2.00 m below defined resources at the Lower 36E Zone
18.15 g/t Au over 4.40 m, on the fringe of defined resources east of the main 36E 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.
“Drill results continue to showcase significant upside to resources at the high -grade O’Brien
project. The majority of current resources are contained within a 1.5 km strike (out of a total strike
length of 4.5 km) and 400 m vertical depth in a prolific gold camp where deposits (including the
old O’Brien Mine) have been mined to depths well below 1,000 m.
The depth potential continues to stand -out with additional high-grade results from the lower 36E
Zone that demonstrate the continuity of mineralization well below the current resource boundary.
All holes drilled 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. Of note, OB -19-98W2 returned 37.76 g/t Au over 2.00 m approximately 720 m
below the surface, and 60 m west and 100 m above previously released intercept of 66.71 g/t Au
over 4.70 m. Drilling continues to demonstrate strong continuity of high-grade mineralization down
to 950 m, and within what appears to be a mineralized trend bearing similarities to that historically
mined at the Old O’Brien Mine. Mineralization remains open for expansion laterally and at depth,
with additional drilling underway to expand mineralization to the west in a largely untested area
below the resource boundary.
In addition, shallower drilling aimed at resource expansion and conversion has continued to deliver
high-grade results in the upper 400 m of the deposit. In particular, drill hole OB -20-127 returned
3.07 g/t Au over 32.20 m close to the western boundary of currently defined resources, including
four high-grade sub-intercepts (5.20 g/t Au over 2.00 m, 7.12 g/t Au over 2.70 m, 6.52 g/t Au over
2.30 m and 8.04 g/t Au over 3.20 m) within and outside the boundary of currently modeled inferred
resources. Our team is currently developing additional drill targets on this part of the deposit which
remains open laterally for resource expansion. Another shallow hole, OB -20-135, drilled 300 m
east of this area returned 18.15 g/t Au over 4.40 m at the fringe of an indicated resource block,
confirming and expanding mineralization 15 m east of a historical intercept of 125.31 g/t Au over
3.05 m.
Our exploration program is focused on three key opportunities for resource expansion: the western
extension of the first mineralized trend defined on Lower 36E, the second mineralized trend
recently highlighted approximately 300 m east of the first trend and on resource expansion
opportunities at shallower depths east and west of these two trends.
Results released so far represent only ~45% of our fully funded 60,000 m program. With three drill
rigs now operating at O’Brien, we look forward to releasing additional updates as we continue to
drill test high potential targets over the coming months.” commented Mario Bouchard, President
and CEO.

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.
Figure 2. High-grade mineralized trend (Lower 36E and F Zone)
Lower 36E Zone (below 600 m) – Expansion drilling at depth
• Hole OB-19-98W2 returned 37.76 g/t Au over 2.00 m core length (vertical depth of 720
m) with visible gold showing in a smoky quartz vein (see photos)
o The intercept was obtained 720 m below the surface at the 36E zone
o 100 m above and 75 m to the west of previously released intercept of 66.71 g/t
Au over 4.70 m (OB-19-92W2b)
• Hole OB-19-98W1 returned 5.70 g/t Au over 2.50 m core length (vertical depth of 950
m, approx.) with visible gold showings (see photo)
o The intercept was obtained 75 m below OB-19-98W2 and 75 m west of OB-19-
92W2b
In addition, OB -19-98W3 drilled approximately 60 m east of OB -19-98W2 also intersected
mineralized zones in the targeted structures including a visible gold showing (see photo), albeit
within a wider, lower grade envelope.

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 extending approximately 300 m laterally
and 350 m vertically below the resource boundary. This area remains a key focus for the current
drilling program with one drill rig currently drilling a first wedge branch from a pilot hole (OB-20-
148) with the objective of testing the western lateral extension of the high-grade mineralized trend
defined on Lower 36E.
Upper 36E Zone (above 600 m) – Resource expansion and conversion drilling
• Hole OB-20-127 returned 3.07 g/t Au over 32.20 m core length (vertical depth of 430.00 m):
o Including multiple high-grade structures including:
▪ 5.20 g/t Au over 2.00 m core length
▪ 7.12 g/t Au over 2.70 m core length
▪ 6.52 g/t Au over 2.30 m core length
▪ 8.04 g/t Au over 3.20 m core length
o Results highlight the opportunity to expand inferred resources in a sparsely drilled area
just above higher-grade intercepts within the main mineralized trend at the 36E Zone.
o The area remains open laterally in both directions
Figure 4. See Assay details for 3.07 g/t Au over 32.20 m (OB-20-127)
• Hole OB-20-135 returned 18.15 g/t Au over 4.40 m core length (vertical depth of 190.00 m)
including:
o 44.80 g/t Au over 0.80 m core length
o 17.33 g/t Au over 2.50 m core length
o 300 m east of main mineralized trend at the 36E zone and 15 m east of historical intercept
which returned 125.31 g/t Au over 3.05 m
o Results demonstrate potential to expand indicated resources in the area.
Drill holes completed within the resource area have generally been successful in confirming high -grade
mineralization within and at the fringe of key Indicated resources blocks. They have also demonstrated the
opportunity to further expand some of these blocks and convert Inferred resources at shallower depths. OB-
20-127 (3.07 g/t Au over 32.20 m), OB -20-123 (8.00 g/t Au over 2.00 m and 5.12 g/t Au over 2.60 m) and
OB-20-125 (6.89 g/t Au over 2.65 m) were completed within and at the fringe of modeled inferred resources
demonstrating continuity of mineralization and highlighting an opportunity to expand resources in an area
that remains open laterally in both directions and sparsely drilled between 430 m and 550 m vertical depth.
Hole OB-20-135 (18.15 g/t Au over 4.40 m) drilled 300 m east of the main mineralized trend at the 36E zone
also appears to highlight the lateral extension of high -grade mineralization at the fringe of Indicated
resources.
Fully funded for the completion of the 60,000 m program
• To date 72 drill holes have been completed for a total of 34,230 m, assays are pending for
6,967 m of drilling in 18 drill holes.
• With approximately $8.5m in treasury, Radisson is fully funded to complete and expand the
60,000 m drill program.
1 Estimated as at July 15, 2020.
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 L td, 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.
