Radisson reports several high-grade intercepts above 15 g/t Au from

expansion drilling along Trend #1 at the O’Brien gold project

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

the “Company") is pleased to announce significant high- grade gold intercepts from the 127,600 m

exploration drill program completed this summer 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- N oranda

and Val-d’Or in Quebec, Canada.

Significant intercepts from resource expansion drilling along high-grade trend #1

o 18.76 g/t Au over 3.10 m including 52.50 g/t Au over 0.90 m (OB-21-269)

o 18.45 g/t Au over 2.20 m including 43.00 g/t Au over 0.90 m and;

o 11.58 g/t Au over 2.00 m including 21.40 g/t Au over 1.00 m (OB-21-265)

o 16.45 g/t Au over 2.00 m including 26.90 g/t Au over 1.00 m (OB-21-262)

o 15.31 g/t Au over 2.00 m including 26.30 g/t Au over 1.00 m (OB-21-307)

Current resources along trend #1 are limited down to a vertical depth of approximately 600 m. Drilling

completed during this campaign expanded high-grade gold mineralization 350 m below current resources

down to 950 m vertical depth . Results have been obtained over a strike length of 100 m , including

amongst others 66.70 g/t Au over 4.70 m , 34.71 g/t Au over 3.00 m, 24.22 g/t Au over 3.00 m and 19.43

g/t Au over 3.40 m.

Results are pending for 10 additional directional drill holes (5,000 m) along trend #2 with visible gold

showings in 4 of those holes.

“Over the last months, our team has been focused at executing the 127,600 m drill campaign completed

this summer. The main objective of the program was to expand the footprint of the O’Brien gold deposit in

a 1.2 km corridor located east of the richest mine by grade in Quebec. This corridor represents less than

25% of the prolific package owned by Radisson along the Larder- Lake-Cadillac Break and results have

been impressive with 152 intercepts grading over 5 g/t Au within 246 holes published. Results from the

42,200 metres drilled along Trend #1 have been spectacular with 60 intercepts over 5 g/t Au, including 27

intercepts over 10 g/t Au within 77 drill holes. High-grade gold mineralization has now been expanded

by more than 350 m below current resources along Trend #1.

Our team is now focused on incorporating the drill program and historical results into our geological model.

We expect Trend #1 and Trend #2 expansion drilling to contribute significantly to the resource estimate

update targeted for completion in the first half of 2023.” Commented Denis Lachance, Interim President

and Chief Executive Officer.

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 Au were analyzed a second

time by fire assay with gravimetric finish at the same laboratory. Mineralized zones

containing visible gold were analyzed with metallic sieve procedure. Standard reference

materials, blank samples and duplicates were inserted prior to shipment for quality

assurance and quality control (QA/QC) program.
