ROUYN-NORANDA, Quebec, May 04, 2023 (GLOBE NEWSWIRE) -- Radisson Mining Resources Inc. (TSX-V: RDS, OTC: RMRDF): ("Radisson" or the "Corporation") is pleased to announce that following the 2022 prospection program on the southern portion of the O'Brien project, ("New Alger" or "New Alger area") it has identified a geological context similar to the Canadian-Malartic complex where it is planning a large scale till sampling campaign (see figure 1).

Why Pontiac Group sediments ("Pontiac Group") located south of the prolific Larder-Lake-Cadillac break could host significant deposits?

In proximity to the O'Brien gold project, the Canadian-Malartic complex has produced near 13.7 million ounces of gold to date and is largely located in the Pontiac Group, where gold mineralization is represented by a large volume of disseminated gold and is spatially related to felsic to intermediate porphyritic intrusions and dykes as well as shear-zones (see figure 2). This mining complex highlights the vast potential for gold in the Pontiac Group.

Why does the New Alger area have so much potential?

• The area represents more than 50 km² in proximity to multiple major auriferous structures.
• A sample collected during the 2022 prospection campaign grading 7.33 g/t Au demonstrated the presence of at least one gold-rich zone in the area.
• With the presence of felsic to intermediate porphyritic intrusions and felsic dykes it has geological characteristics similar to historical and operating mines (figure 2).
• The area is located in lateral continuity of the AMM mine from which approximately 83,475 tons were extracted at a grade of 4.54 g/t Au from 1939 to 1942 and that had estimated reserves of 219,000 tons grading 4.46 g/t Au.

"I am thrilled to report that we will be conducting this important till sampling program in upcoming weeks. While the impressive O'Brien project remains our top priority and focus, we see an excellent opportunity to start unlocking the value of the New Alger area at a low cost where our vast landholding has potential to yield new gold discoveries," Commented Denis V. Lachance, Interim President and Chief Executive Officer.

How will the Radisson team attempt to make a new discovery?

After evaluation, Radisson's geological team determined that a major glacial till sampling campaign (300-400 samples) is the best method to target large zones with disseminated gold potential. Following a successful campaign, stripping, trenching and/or drilling would eventually allow to precisely delineate the strike of a potential discovery.
