ROUYN-NORANDA, Quebec, Sept. 02, 2020 (GLOBE NEWSWIRE) — 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 of 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 approximately 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.Press release HighlightsPotential for a third high-grade mineralized trend, approximately 900 m east of the old O’Brien mine, with multiple high-grade intercepts outside the boundary of defined resources.Hole OB-20-149 returned 45.86 g/t over 2.10 m (500 m vertical depth) including 92.90 g/t over 1.00 m with visible gold showings (see photo 1 and photo 2) obtained 260 m below defined resources.Hole OB-20-146 returned 17.90 g/t over 2.15 m (105 m vertical depth) and 21.29 g/t over 2.00 m (260 m vertical depth).Hole OB-20-144 returned 5.79 g/t over 2.00 m (135 m vertical depth)Highlights opportunity for significant resource growth in a largely undrilled areaMineralization has been traced down to 500 m vertical depth, with the zone open for expansion laterally and at depth.Opportunity for additional resource growth within a second mineralized trend located approximately 600 m east of the old O’Brien MineHole OB-20-142 returned multiple high-grade intercepts east of defined resources in the area including 5.58 g/t over 2.00 m, 11.02 g/t over 2.00 m and 5.81 g/t over 2.00 mCurrent resources in the area are largely above 360 m vertical depth and mineralization remains open for expansion laterally and at depth.    Drilling continues to expand the first mineralized trend (36E Zone), approximately 300 m to the east of the old O’Brien Mine and below the resource boundaryHole OB-20-145 returned 12.48 g/t Au over 2.00 m core length (vertical depth of 725 m)The majority of defined resources in the area are within 600 m vertical depth.Drilling to date demonstrates continuity down to approximately 950 m, within an area extending approximately 300 m laterally and 350 m vertically below the resource boundary.Mineralization is open for expansion laterally and at depth below 950 m.With the close of the New Alger acquisition, Radisson’s claims cover a prospective strike length of 5.9 km along the prolific Cadillac BreakProspective strike now includes approximately 3 km east and 3 km west of the old O’Brien Mine, historically the highest-grade gold mine in Quebec (production of 587 k oz at 15.25 g/t average grade from 1926 – 1957).Drilling thus far has mostly been limited to 1 km to the east of the old mineThe company plans to systematically step out further to the east as well as initiate drilling on high potential targets to the west of the O’Brien Mine.45,771 m of drilling completed to date with assays pending for approximately 12,771 mReleased results represent 55% of a planned 60,000 m program.The company is funded to expand the program to over 75,000 m.Figure 1 Cadillac Mining Camp Geological Map: Combined O’Brien & New Alger PropertiesFigure 2 O’Brien project longitudinal section looking NorthNotable drill resultsVG denotes the presence of visible goldCore length or down hole width.

A capping factor of 60 g/t Au was used in the 2019 resource estimateTable includes only intercepts that meet 5 g/t Au cut-off and minimum mining width constraints used in the 2019 MRE.Potential third high-grade mineralized trend (Kewagama area), 900 m east of the O’Brien MineHole 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 4)° The intercept was obtained 260 m below defined resources in a sparsely drilled area 900 m east of the old O’Brien MineHole OB-20-146 returned multiple high-grade intercepts including:° 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
° 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)° 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.Figure 3. Third potential high-grade mineralized trend, 900 m east of the old O’Brien MineFigure 4. Visible gold showing in OB-20-149Results 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 within the second mineralized trend, 600 m east of the old O’Brien MineHole 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:° 5.58 g/t Au over 2.00 m from 42.00 m core length
° 11.02 g/t Au over 2.00 m from 250.60 m core length
° 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 ongoing 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 boundaryHole OB-20-145 returned 12.48 g/t Au over 2.00 m core length (vertical depth of 725 m)° The intercept was obtained below the eastern boundary of resources at the Lower 36E Zone.
° 120 m above a previously released intercept of 66.71 g/t Au over 4.70 m (See OB-19-92W2b)
° 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 extending 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 programTo 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/QCAll 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.Qualified PersonRichard Nieminen, P.
