READ TIME: 7 MINUTES | RESOURCE TALKS HAS BEEN COMPENSATED BY RADISSON MINING FOR THIS CONTENT
TL;DR
Radisson Mining, led by CEO Matt Manson, is exploring its O’Brien project with a focus on deep, narrow high-grade gold veins. Recent highlights include a 31.2 g/t intercept over 8 meters at 1,700 meters depth and the discovery of the “Jewelry Box,” a vertical high-grade shoot returning 1,300 g/t over one meter. The company is pursuing a hub-and-spoke model, targeting nearby mills like IAMGOLD’s Doyon to minimize capital costs. With a defined 9-10 year mine life, Radisson is balancing exploration with long-term resource development and plans deeper drilling and metallurgical studies in 2025. They aim to unlock the deposit’s full potential without building standalone infrastructure.
- Radisson Mining is successfully navigating the challenges of narrow, high-grade gold mineralization at O’Brien, focusing on a mix of broader zones and localized high-grade intervals.
- Deeper drilling efforts, reaching unprecedented depths of 1,700 meters, have validated the project’s continuity and potential scale, supporting the hypothesis of up to 3 million ounces of gold.
- The company’s hub-and-spoke mining strategy, leveraging existing mills like IAMGOLD’s Doyon, minimizes capital expenditures and shortens development timelines.
- Metallurgical studies and evolving resource modeling, including lower cut-off grades, are critical to aligning the project with modern economic and environmental standards.
- Plans for 2025 emphasize deeper drilling, advancing studies on the Jewelry Box high-grade shoot, and preparing for a PEA to showcase the project’s sustainable, long-term potential.
How Will Radisson Manage the Narrow, High-Grade Orebodies at O’Brien?
Radisson Mining’s O’Brien project boasts impressive grades, including recent results of 62 g/t over a one-meter interval. CEO Matt Manson acknowledges the variability and narrow width of the deposit, emphasizing its historic mining legacy and geological complexity. “We’re not running away from the fact that this is a high-grade but narrow deposit,” said Manson. The company is focused on balancing resource-grade material with broader zones of mineralization, including dilution considerations from wall rock during mining.
Recent drilling has confirmed the deposit’s hallmark: broader mineralized zones often dominated by a single high-grade interval. For example, a 6-meter intercept at 27.6 g/t was driven by a 100 g/t result over one meter. These insights align with the historical mining attributes of the O’Brien mine, where quartz-sulfide veins delivered localized high-grade gold.
Why Drill So Deep?
Radisson has ventured deeper than ever before, with notable success. One highlight: a 31.2 g/t intercept over 8 meters, including an exceptional 242 g/t over one meter, at a depth of 1,700 meters. “This was the first hole drilled beneath the old mine in 70 years,” Manson noted. He explained that the deeper drilling program, while challenging and costly, provides valuable directional guidance to evaluate the deposit’s scale and continuity.
By projecting mineralization trends downward, the company aims to demonstrate the geological and economic potential of the deposit. “This is about courage in exploration,” Manson said, adding, “Five of the seven deep holes have returned resource-grade material.”
What’s the Expected Scale of the Resource?
Radisson’s exploration efforts aim to uncover a deposit potentially spanning 2 kilometers in depth, which could yield up to 3 million ounces of gold. “The old mine produced half a million ounces down to 1 kilometer,” Manson explained. By extending the mineralization downward, Radisson hopes to replicate or exceed this figure. While some results remain exploratory, the consistent geology and high success rate of deeper drilling reinforce optimism about the project’s scale.
Why Target a Hub-and-Spoke Mining Model?
Unlike standalone operations, Radisson envisions O’Brien as part of a regional hub-and-spoke mining model, leveraging existing processing facilities. The company’s MOU with IAMGOLD explores using the Doyon mill, reducing capital expenditures and environmental impact. “Building a mill and tailings facility doesn’t make sense for this project,” Manson stated. By focusing on integration into existing infrastructure, Radisson minimizes upfront costs and accelerates development timelines.
Is Mining Economically Viable at 1,700 Meters?
Despite the depths, Manson believes O’Brien remains economically viable. “We don’t see any impediment to mining at least down to 1 kilometer, and likely to 2 kilometers,” he said. Preliminary evaluations indicate sufficient grades and favorable ground conditions, with RQD data supporting the rock’s competency. Future mine design considerations, including vertical conveyors to reduce haulage costs, will be critical to achieving economic feasibility.
Why Change Cut-Off Grades?
Radisson’s resource modeling is evolving, with the potential to lower cut-off grades from 4.5 g/t to 3 g/t. This adjustment reflects improved recovery rates, higher gold prices, and continuity of mineralized zones at lower grades. Manson clarified, “At a 3 g/t cut-off, the resource becomes much more continuous, improving economic modeling.”
What’s the Significance of the “Jewelry Box” Discovery?
The “Jewelry Box,” a vertical high-grade gold shoot, returned a staggering 1,300 g/t over one meter, reigniting interest in the project’s potential. Believed to be the source of historic museum-grade gold samples, this discovery underscores the localized high-grade characteristics of O’Brien. “If this zone continues to surface, it could provide substantial early-stage cash flow,” Manson highlighted.
How Was Such a High-Grade Zone Missed Before?
The “Jewelry Box” zone’s narrow geometry made it elusive. “You’re trying to intersect a two-meter-wide pencil-shaped structure,” Manson explained. With updated drilling and exploration techniques, Radisson plans to trace the zone to surface, potentially uncovering new high-grade opportunities.
What Challenges Come with Drilling at These Depths?
Drilling at depths exceeding 1,700 meters presents logistical and financial challenges. According to Manson, “That hole cost about $250,000, but it validated our geological model perfectly.” Ground conditions have been favorable, and Radisson’s efficient drilling setup—including the ability for crews to return home daily—has kept costs manageable at approximately $175 per meter. Despite the increased time and expense, the deeper holes are considered crucial for understanding the project’s full potential.
What Role Do Metallurgical Studies Play?
Metallurgical studies are a priority as Radisson evaluates processing options for O’Brien’s ore. Collaborating with IAMGOLD, the company is analyzing flow sheet modifications needed for the Doyon mill. “We’re seeing no red flags so far,” Manson noted. This work is essential for defining the project’s economics and advancing towards a preliminary economic assessment (PEA).
How Does Radisson Balance Exploration with Development?
Radisson is carefully balancing near-term exploration success with long-term resource development. Manson stressed the importance of defining the project’s scope while maintaining a sustainable approach. “With a 9- to 10-year mine life already defined, we’re in a good place,” he explained. The company’s hub-and-spoke model reduces the pressure to build standalone infrastructure, allowing resources to focus on strategic exploration.
Will Radisson Seek a Partnership?
While Radisson is open to collaboration, the company remains independent. “Our job is to deliver value for shareholders,” Manson emphasized. The IAMGOLD MOU is strictly technical, with no commercial terms, allowing Radisson to maintain flexibility. With multiple mills in the region, the company sees several options for processing its ore, further underscoring its strategic positioning.
What Are Radisson’s Plans for 2025?
Looking ahead, Radisson plans to:
- Focus on deeper drilling to expand the resource base.
- Advance studies on the Jewelry Box zone and explore its potential at surface.
- Complete metallurgical work and provide guidance on processing options.
- Continue baseline environmental work and prepare for permitting requirements.
The company will also finalize its technical studies with IAMGOLD, aiming to begin PEA work in early 2025. “We’re ensuring that all the pieces are in place for sustainable and economically viable development,” Manson concluded.
