Radisson reports multiple high-grade intercepts including 37.86 g/t Au over

2.00 m and 12.69 g/t Au over 3.50 m, expanding mineralization laterally and

at depth in the gap between current resources and the old O’Brien Mine

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 ongoing 130,000

m exploration drill program 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-Noranda and Val-d’Or in Quebec,

Canada.

Key highlights

• Significant intercepts from exploration drilling along high-grade trend # 0, representing the gap

between current resources and the old O’Brien mine

o 37.86 g/t Au over 2.00 m including 75.60 g/t Au over 1.00 m (OB-21-221W3)

o 12.69 g/t Au over 3.50 m including 27.10 g/t Au over 1.60 m (OB-21-221W4)

o 7.70 g/t Au over 2.00 m including 12.10 g/t Au over 1.00 m (OB-21-221W2)

• Results include 3,376 m directional drill campaign comprising one pilot hole (OB -21-221) and 7

branches to drill test an area extending approximately 150 m along strike and between 75 m and 250

m depth below the limits of previous drilling in the area.

o All of the holes intersected the targeted mineralized structures including 4 visible gold occurrences

o Savings of approximately 3,555 m (51%) using directional drilling technology

• New and previously released results (including 92.89 g/t Au over 2.60 m, 47.10 g/t Au over 2.60 m ,

10.87 g/t Au over 3.15 m and 14.90 g/t Au over 8.20 m ) demonstrate continuity of high -grade

mineralization in the area down to a vertical depth of 750 m.

o Modeled resources in the area are mostly limited to within 240 m from surface.

• 130,000 m drill program underway at O’Brien

o 121,750 m (245 holes) completed as of March 31, 2022 with results pending for 2 4,000 m in 5 0

holes of which 27 holes intersected visible gold.

o Cash balance of approx. $7.0M as of April 15, 2022

“The first batch of results from directional drilling completed as part of the ongoing program highlight the

significant high -grade potential along trend #0 , which represents the gap between currently defined

resources along trend #1 and historically mined structures at the old O’Brien Mine . Drill results to date

demonstrating the continuity of high-grade mineralization down to more than 750 m depth and up to 140

m west of current resources established on Trend #1. Drill results from this sector have been impressive,

with 36 holes published so far of which 20 have intersected visible gold including 14 intercepts grading

over 5 g/t Au.

Overall, results from our ongoing 130,000 m drill program continue to impress with 195 holes published so

far including 131 intercepts grading over 5 g/t Au. We look forward to obtaining additional results from all

5 high-grade trends (trend 0, 1, 2, 3, 4) established east of the old O’Brien mine as we continue to focus

on expanding the footprint of the deposit. Results are pending from 50 holes of which 27 have intersected

visible gold occurrences. Pending results include approximately 10,000 m ( 17 holes) from our deep

directional drill program aimed at testing some of our most promising deeper targets along trend #1 and

#2. Our deep directional drill continues to remain a key priority with two rigs systematically testing deeper

high-grade mineralized structures along trend #1 and #2. We look forward to building momentum with

significant news flow in the weeks and months ahead” Commented Rahul Paul, President and Chief

Executive Officer.

Drilling at O’Brien continues to validate the litho-structural model while

highlighting resource growth potential laterally and at depth

Drilling to date has con tinued to define and expand almost five high -grade mineralized

trends (trend 0, 1, 2, 3, 4) , located within a 1,200 m strike 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 gold grading

15.25 g/t Au).

Drilling so far has demonstrated continuity of mineralization well below the boundary of

defined resources in all defined trends, which remain open for expansion laterally and at

depth. In trend #0, drilling has traced mineralization to a depth of 750 m, while current

resources are mostly within the first 240 m. In trend #1, drilling has highlighted continuity

of mineralization down to a vertical depth of 950 m, while current resources are mostly

limited to a vertical depth of approximately 600 m. In tren d #2, drilling has highlighted

continuity of mineralization down to a vertical depth of over 800 m, while current resources

are mostly within 400 m from surface. In trend #3, drilling has traced mineralization down

to 500 m vertical depth from surface. Cur rent resources are mostly confined to within a

vertical depth of 240 m. In trend #4, drilling has traced mineralization down to a vertical

depth of approximately 330 m.

In addition, the Company has completed an initial 5,700 m exploration program at O’Brien

West. In addition to validating geological information from historical drill holes, initial

results showcase potential for additional high-grade discoveries in this area. O’Brien West

remains open in all directions ( along strike and at depth ), with resu lts indicating strong

depth continuity in lithological units identical to those observed along strike to the west,

reaffirming the upside potential from approximately 2.5 km of largely untested prospective

ground west of the O’Brien Mine along the prolific Larder-Lake-Cadillac break.

Almost all drilling conducted as part of the ongoing campaign has been within a strike

length representing only a small portion of more than 5.2 km of prospective strike that

Radisson controls along the Cadillac Break. Given c urrent geological understanding, the

ongoing validation of the litho -structural model, the company estimates there is strong

potential for additional high -grade gold trends to be discovered along the whole 5.2 km

prospective land package on the prolific Larder-Lake Cadillac Break.

121,750 m of drilling completed to date with assays pending for approx. 24,000 m

This release represents approximately 3,376 m of drilling in 8 drill holes. Released results

to date (since the commencement of drilling in August 2019) represent approximately 75%

of the approximately 130,000 m planned thus far. 1 As of April 15, 2022, the company

remains well funded with approximately $7.0 m in cash.
