Radisson pulls 68 g/t gold from nearly a mile down at O'Brien

Radisson Mining drilled into the rock beneath the former O’Brien mine in Quebec’s Abitibi belt and hit 68.24 grams of gold per tonne over 6.2 metres — rich enough that a single tonne of that rock carries more than two ounces of gold. The intercept sits about 1,514 metres straight down, roughly a mile below surface, in holes drilled between 1,511 and 1,517.2 metres downhole. Inside it, one metre ran 384 grams per tonne, coarse visible gold in the core. All eight holes in this batch hit, and management now claims an 83% hit rate across 128 holes.

That headline number works out to about 423 gram-metres — grade times thickness, the way geologists measure how much metal a hole actually found — which lands in the top tier of anything drilled anywhere. It matters because the old O’Brien mine produced more than 500,000 ounces at over 15 grams per tonne, and Radisson is now tracing those same narrow high-grade veins, wrapped in wider 1-to-4 gram halos, down toward two kilometres. Matt Manson runs the company; he built the Valentine Gold Project at Marathon Gold before its C$345 million combination with Calibre in 2024. Backing him: Agnico Eagle, one of the world’s largest gold producers, closed a C$57.16 million strategic investment in September 2026, taking roughly 10.45% of the company. The stock rose 40% over three months while the junior-gold GDXJ index gained 16.4% and gold itself moved 4.7% — 2.4 times the peer move, on a re-rating that started around day 41 of the chart, so this is a company-specific event, not the tide lifting everything.

Now the honest part. True widths are disclosed only as a broad 30-to-80% range of core length, so that 6.2-metre intercept could be as thin as about 1.9 metres of actual vein. Grades are uncapped, and the 384 g/t visible-gold sample dominates the average — that’s nugget-effect risk, where a single coarse fleck skews the number. These are wedge branches fanning off a common pilot hole, not separate collars, so the consistency shows local continuity, not wide coverage; the release states no horizontal step-out distance, only a down-plunge extension within the same trend. Radisson is pre-revenue, and its 140,000-metre program — eight rigs, depth now pushed to 2.5 kilometres — needs continued capital. Watch for regular drill releases and a step-by-step resource update as drilling passes the December 31, 2025 cut-off.
