At $5,000 an Ounce, the Next Wave of Gold Mines Is Already in the Ground

The most recent news (March 02, 2026) announces a significant update to the Mineral Resource Estimate (MRE) for the 100%-owned O'Brien Gold Project. Key highlights include an 82% increase in Inferred Mineral Resources to 1.69 million ounces (10.37 Mt @ 5.08 g/t Au) and an 8% increase in Indicated Mineral Resources to 0.63 million ounces (3.49 Mt @ 5.59 g/t Au). This update incorporates 428,440 meters of drilling and reflects a strategic shift toward a "bulkier" mining model, utilizing a lower 2.2 g/t Au cut-off (down from 4.5 g/t in 2023) to capture wider mineralized envelopes amenable to modern mechanized mining.

This news is Material - Positive. It validates the "proof-of-concept" drilling strategy initiated in late 2024, proving that the O'Brien system maintains continuity and scale at depth (down to 1,000m+). - Resource Scale: Total inventory (Indicated + Inferred) has grown from ~0.95 Moz in 2023 to ~2.32 Moz. This moves the project into a different tier of attractiveness for mid-tier and major producers in the Abitibi region. - Geological De-risking: The 84% success rate in step-out drilling and the delineation of at least eight parallel veins beneath the historic mine significantly reduce the risk of "losing the vein" at depth. - Economic Viability: While the average grade decreased by ~12% due to more restrictive capping and a lower cut-off, the increased tonnage supports a higher throughput model (1,200 tpd in PEA), which improves project economics in a high gold price environment ($2,500/oz used for MRE).

Radisson Mining is focused on the O'Brien Gold Project in the Bousquet-Cadillac mining camp, Quebec. O'Brien is a former high-grade producer (>15 g/t). The project benefits from being adjacent to the Trans-Canada Highway and existing 112kV power lines. The flagship strategy relies on "toll-milling," avoiding the C$100M+ cost of building a new mill by using nearby facilities.
