Radisson Extends High-Grade Gold Mineralization at O'Brien to 1.9 Kilometres Depth with Latest Drill Results
Deep Drill Success Validates O'Brien Resource Potential Despite Valuation Run-Up

Executive Summary
- Radisson Mining Resources announced high-grade gold assay results from sixteen new drill holes at its 100%-owned O'Brien Gold Project in Quebec on April 30, 2026.
- The headline result comes from hole OB-26-384, the deepest hole ever drilled at the project, intersecting 4.54 g/t Au over 12.0 metres at a vertical depth of 1,900 metres.
- This intercept is approximately 350 metres below the current limit of mineral resources in this area as defined by the March 2026 Mineral Resource Estimate (MRE).
- The company reports a 79% success rate for completed drill holes since December 2024, with seven out of seven holes in central target areas returning intercepts consistent with existing resources.
- The drilling program is part of an ongoing 140,000-metre step-out plan designed to test mineralization down to a 2-kilometre depth floor.
- Seven drill rigs are currently active at the project with 22 additional holes completed or in progress.
Material Impact
- The news confirms the company's exploration thesis that the O'Brien gold system is open at depth, validating the March 2026 MRE update which already indicated significant resource growth potential.
- While the results are positive and high-grade (4.54 g/t Au), they fall within the expected parameters of the announced 140,000-metre drill program funded in late 2025.
- The extension to 1,900 metres reduces exploration risk for future resource conversion but does not represent a sudden, unexpected material change like a takeover or new strategic investor entry.
- Given the stock price has already rallied from $0.30 to over $1.00 in anticipation of these results and the March MRE update, much of this positive information is likely priced in.
- The news supports continued development but does not alter the fundamental timeline for production (estimated 3.5-year permitting process) or immediate cash flow generation.
