Radisson Mining Resources Inc. (RDS:TSX.V; RMRDF:OTCQB) reported an overview of ongoing geological modelling at its 100% owned O'Brien Gold Project in the Abitibi region of Québec. The company highlighted new vein-hosted mineralization beneath the historic O'Brien gold mine that has emerged from its continuing and fully funded 140,000-meter step-out drill program. Since late 2024, fifteen drill wedges have been completed from pilot hole OB-24-337, outlining at least eight parallel veins over a 250-meter by 700-meter area and showing continuity of mineralization with former mine workings.
Matt Manson, President and CEO, said in a company news release that the geological model is developing alongside the drill results published over the past 12 months. He said the company had been seeing success across the breadth of the Project, including an 84% success rate in intercepting gold mineralization with grades and thicknesses consistent with the Project's mineral resources. He said the multi-vein system being delineated below the former mine and the continuity of high-grade intercepts support the company's geological understanding. He noted that the 140,000-meter step-out drill program is scheduled to continue through 2026 and into the first half of 2027 and that the company intends to issue step-by-step updates to its Mineral Resource Estimate, with the first expected prior to the end of the first quarter of 2026.
Radisson reported that gold mineralization at O'Brien occurs within quartz sulphide veins hosted in volcanic rocks, conglomerates, and porphyritic andesitic sills of the Piché Group in contact with the Larder Lake Cadillac Break. The company stated that the historic O'Brien mine produced over half a million ounces of gold at an average grade exceeding 15 g/t Gold (Au) over a vertical extent of at least 1,000 meters.
The company described its 140,000-meter step-out drill program, which aims to determine the overall scope of mineralization at the Project to a depth of 2 kilometers. Radisson stated that 35,000 meters were completed in 2025, 72,500 meters are budgeted for 2026, and a further 32,500 meters are scheduled for the first half of 2027. The program uses pilot holes followed by wedges and directional drilling. Radisson previously announced the expansion of the program in October 2025 to employ eight drill rigs. The program covers drilling beneath the historic mine, beneath modern mineral resources to the east, and at the Thompson Cadillac area west of the mine. The company reported that 84% of completed drill holes have intersected gold mineralization.
A particular focus has been drilling below the historic O'Brien Mine East, where mining ceased in 1957 at the 1,000-meter level. In December 2024, deep pilot hole OB-24-337 intersected 31.24 g/t Au over 8.0 meters, including 242.0 g/t Au over 1.0 meter at approximately 1,500 meters vertical depth. Radisson stated that fifteen wedges from this pilot hole have since been reported, along with the completion of pilot hole OB-25-378 to 1,640 meters. All drill holes have intersected gold mineralization with grades and lengths consistent with the Project's mineral resources.
The company outlined its vein modelling approach, which uses dynamic wireframed domains updated as drilling progresses. Radisson reported that historic mining focused on a main central high-grade stope and that parallel veins identified through historic drilling were left undeveloped. The company referenced historic effective grade cut-offs between 7 and 8 g/t Au.
Radisson reported that two pilot holes and fifteen wedges, combined with historic data, support a model of at least eight wireframed veins covering an area approximately 250 meters east-west by 700 meters vertically. Extrapolation distances in the model are set at 50 meters along strike and 100 meters down plunge. The model is open in all directions.
The company noted that vein V3 CEN shows continuity with the historic mining stope and returns consistently high-grade intercepts, implying a shoot of at least 1,600 meters vertical continuity. Reported highlights include 31.24 g/t Au over 8.0 meters in OB-24-337, 16.43 g/t Au over 8.1 meters in OB-25-337W7, 29.93 g/t Au over 2.2 meters in OB-25-337W3, and 47.70 g/t Au over 1.0 meter in OB-25-337W5.
Radisson stated that drilling is ongoing with seven rigs active and an eighth to be mobilized shortly. The second wedge from pilot hole OB-25-378 is in progress. The company expects to report drill results on a regular basis as the 72,500 meters of drilling budgeted for 2026 progress. Radisson further intends to update the Project's Mineral Resource Estimate on a step-by-step basis, with the first update expected prior to the end of the first quarter of 2026.
"Eight Veins, Eight Rigs, and a Resource Update on Deck"
In a February 12 report from The Gold Advisor, Senior Analyst Jeff Valks discussed developments at Radisson Mining Resources. Valks quoted the company's CEO, stating that "We are drawing attention to the geological model that is developing in concert with the drill results we have been publishing over the past 12 months." He noted the company's reported "impressive 84% success rate in intercepting gold mineralization" with grades and thicknesses "consistent with the Project's mineral resources." Valks wrote that Radisson's work supported a model of "at least eight separate parallel veins" covering an area of approximately 250 meters by 700 meters and described the company's statement that the model was "open in all directions."
He highlighted the company's comments regarding the V3-CEN vein, quoting Radisson's description of a "remarkably consistent" high-grade shoot with at least 1,600 meters of vertical continuity. Valks also referenced the company's view that historic mining was "high-graded," leaving "significant quantities of mineralized material unmined." He noted the company's outlined drilling schedule of 35,000 meters completed in 2025, 72,500 meters budgeted for 2026, and 32,500 meters scheduled for the first half of 2027, as well as Radisson's plan to issue "step-by-step updates" to its Mineral Resource Estimate.
Valks stated that the stock was a Buy and wrote that Matt Manson described the project "not as a bespoke deposit of extreme grade and limited scale, but as an extensive Abitibi vein deposit with a substantial inventory of mineralized material amenable to modern mechanized mining."
Ongoing Drilling and Resource Updates
Radisson reported several ongoing workstreams that are expected to continue throughout the drill program. In investor materials, the company stated that the 140,000 meter step out drill program will continue with eight active drill rigs through 2026 and into the first half of 2027. It reported that 72,500 meters of drilling are budgeted for 2026, with an additional 32,500 meters scheduled for the first half of 2027.
The company noted that drilling targets include areas beneath the historic mine, areas beneath modern mineral resources to the east, and the Thompson Cadillac area west of the mine, which will be drilled for the first time since 2021. Objectives will be reassessed progressively based on results obtained.
