Radisson Intersects 2.0 Metres Grading 33.2 G/T GOLD Within Wider Intercept of 19.6 Metres Grading 4.5 G/T GOLD at O’Brien

Drill Results

TSXV: RDS

For immediate release Press release No. 07, 2017

RADISSON INTERSECTS 2.0 METRES GRADING 33.2 G/T GOLD WITHIN WIDER

INTERCEPT OF 19.6 METRES GRADING 4.5 G/T GOLD AT O’BRIEN

Rouyn-Noranda, Quebec, June 20 , 2017: Radisson Mining Resources Inc. (TSXV: RDS)

(“Radisson” or the “ Company") is pleased to announce additional results from the ongoing

20,000 m drill program at the Company’s O’Brien gold project located along the Larder -Lake-

Cadillac fault halfway between Rouyn-Noranda and Val-d’Or, Quebec. Drilling results continue to

demonstrate lateral and vertical continuity of current mineral resources of the O’Brien deposit.

Moreover, Radisson continues to confirm the presence high-grade gold intercepts within wider

low grade mineralized envelopes, as first highlighted in May 9th, 2017 Press Release (OB 17-25

returned 1.0 g/t Au over 93 metres).

Since the last update, results have been received for five drill holes (OB-17-26 to OB-17-30).

With two drill -rigs active onsite, the company is currently drilling hole OB-17-45. Assays are

currently pending for 14 holes for a total of 7,425 m.

Highlights:

• Drill hole OB -17-29 intersected 19.6 metres grading 4.5 g/t Au at a depth of 354 m and

including high-grade gold intervals of 33.2 g/t Au over 2.0 m and 8.6 g/t Au over 1.0 m (see

figure 1 and 2).

• Drill hole OB -17-30 intersect ed 24.3 metres grading 1.5 g/t Au at a depth of 532 m,

including 10.7 g/t Au over 1.2 m. Drill hole OB-17-30 targeted up-dip extension of drill hole

OB-16-05 that returned gold values of 17.6 g/t Au over 1.4 m.

• Drill hole OB-17-26 intersected 47 metres grading 1.2 g/t Au at a depth of 460 m, including

6.5 g/t Au over 3.0 m.

Exploration Update

Up to date, 8 exploration drill holes for a total of 3,867 metres were completed on high -priority

exploration targets. Four of these drill holes were completed in the Cadillac sediments, north of

the Larder -Lake-Cadillac fault, whereas four drill holes were completed south of the O’Brien

deposit within the Pontiac sediments. Results are currently pending.

Historical drill core re-logging and assaying

In light of the wide zone of low grade gold mineralization recently intersected in drill hole OB 17-

25, OB -17-26, OB -17-29 and OB -17-30, the company intends to review, re- log and assay, if

warranted, the near -surface sections of historical drill core from the 36E area. Prior to 2016,

most of these holes have incomplete assay sequence inside the Piche group. Only highly

mineralized zones were assayed without paying attention to a possible wider low -grade

envelope model.

Mario Bouchard, President and CEO commented: “We are very excited by today’s results as we

continue to encounter high -grade gold mineralization in extension of current resources of the

36E area. We are also excited to pursue the exploration- drilling program with a second dr ill-rig.

The Cadillac group sediments, where historical drilling have returned gold values is of particular

interest for Radisson, we are excited to drill this area of the property which could lead to

significant discovery outside current resources”.

All drill cores in this campaign are NQ in size. A ssays 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 Techni -Lab Actlabs in Ste- Germaine-Boulé in

Abitibi, Quebec. Samples yielding a grade higher than 5 g/t were analyzed a second time by fire

assay with gravimetric finish at the same laboratory. Samples containing visible gold were

analyzed with metallic s ieve procedure. Standard reference materials and blank samples were

inserted prior to shipment for quality assurance and quality control (QA/QC) program.
