Radisson Mining Resources Inc. announced that following the 2022 prospection program on the southern portion of the O'Brien project, it has identified a geological context similar to the Canadian-Malartic complex where it is planning a large scale till sampling campaign. 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. This mining complex highlights the vast potential for gold in the Pontiac Group.

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 por Murphyritic intrusions and felsic dykes it has geological characteristics similar to historical and operating mines.

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.
