Radisson Mining Resources Inc. takes great pleasure in announcing the commencement of a completely funded 20,000 m drill program at its wholly owned O’Brien gold project, situated along the Larder-Lake-Cadillac Break in Cadillac, Québec.

At present, two drill rigs are on site and operating at O’Brien with around 20,000 m to be completed by the end of January 2020. The F Zone, 36E and Kewagama zones of the O’Brien project are situated within a corridor spanning 1.5 km directly south of the L-L-C. The Vintage zone lies parallel to and from 30 to 85 m north of the L-L-C.
New Litho-Structural Model Unlocks the “Jewellery” Box Mystery of the High-Grade O’Brien Mine
The new structural model and resource estimate has led to a much better understanding of the O’Brien gold project, underlining a strong agreement with the historic data and geometry of the Old O’Brien mine, where just three veins returned 90% of the historic production at an average grade of 15.25 g/t Au.
Exploration Below 550 m
The focus of one diamond drill rig will be on the vertical expansion of the highest-grade mineralized shoots on the 36E and F Zone, where high-priority exploration targets were determined beneath current resource.
The depth of the deepest level of the resource area is just 550 m and is largely untested underneath to date. Two historical drill intercepts have returned 13.68 g/t Au over 0.32 m and 17.46 g/t Au over 1.00 m below depths of 1000 m.
Other mines in the region have exceeded depths well below 1000 m. Present mineral resource area is located close to the old O’Brien mine where historic production touched a vertical depth of 1100 m and continues to be untested underneath.
At present, the company is drilling a mother hole 150 m below the deepest level of the resource area, from an arrangement where multiple drill holes and wedges will be finished for an initial 9000 m.
Exploration Potential Along Strike, to the North, Resource Expansion and Conversion
The second diamond drill rig is now focused on the Kewagama zone, which is relatively shallow and includes high-priority exploration targets set up for resource expansion and conversion for around 4000 m.
By 2019, the second rig will also be carrying out exploration drilling on the Vintage Zone (North of the Larder-Lake-Cadillac Break). The New Litho-Structural model also unraveled exploration targets on O’Brien West, situated a few meters west of the old O’Brien mine.
20,000 m Drill Program
Recently, high-priority targets were determined on the basis of the New Litho-Structural interpretation that concluded in 2019. This analysis resulted in a New Resource estimate reported in July, leading to a significant increase of contained gold ounce per vertical meter as grade and contained ounces have increased over all categories at cut-offs.
The resource expansion and exploration of prospective zones established with our New model, will allow for further validation of this New geological understanding. With a strong treasury and a fully financed drill program, we are confident we can generate strong value for our shareholders.
