Radisson Expands O’Brien Gold Project Drilling to 140,000 Metres

O’Brien Gold Project Targets Deep High-Grade Expansion

Radisson Mining Resources has expanded its drilling programme at the O’Brien gold project in Québec to 140,000 metres. This move significantly extends its original exploration plan. Moreover, it aims to uncover high-grade gold mineralisation deeper than current resource boundaries, targeting depths of up to 2 kilometres. To achieve this, the company is using up to eight drill rigs to accelerate exploration and data collection.

Initial results strongly confirm the project’s deep potential. For example, a recent pilot hole yielded 31.24g/t gold over 8 metres. Notably, this included a 1-metre interval grading 242g/t at about 1,500 metres depth. This zone lies 500 metres below the last mining stope. As a result, it supports the belief that O’Brien’s mesothermal gold system extends well beneath current workings.

The expanded drilling will continue through 2026. It builds on the 35,000 metres of drilling Radisson expects to complete by late 2025. Furthermore, the goal is to revise the current mineral resource estimate (MRE). Radisson aims to unlock significant new gold ounces with results released regularly.

Radisson’s Strategic Vision for Resource Growth at O’Brien

Radisson CEO Matt Manson said recent high-grade intercepts validate the vision of a deeper, long-life deposit. The team targets 3–4 million ounces of gold in 15–20 million tonnes grading 4.5–8g/t gold. These figures reflect the geological continuity of the O’Brien system along the Larder Lake-Cadillac Break.

The current MRE includes 580,000oz of indicated resources at 8.2g/t gold and 930,000oz of inferred resources at 4.4g/t gold. This is detailed in the project’s preliminary economic assessment (PEA). The mineralisation occurs in quartz-sulphide veins within mafic volcanic and sedimentary sequences of the Piché Group, a well-known host in the Abitibi region.

Radisson’s recent $25 million financing strengthens its treasury. This ensures funding for the expanded programme. The company’s sole focus on O’Brien underlines its commitment to unlocking one of Québec’s most promising high-grade gold assets.

SuperMetalPrice Commentary:

Radisson’s expansion at the O’Brien gold project shows growing confidence in the mineralisation’s depth and scale. The clear geological model and strong early results suggest a long-term strategy for transformational growth. Directional drilling tests deep zones efficiently, demonstrating technical skill and cost control. As markets favour high-grade, well-located gold projects, O’Brien could become a standout deposit in Abitibi. Investors should watch for assay results and the updated resource model expected in 2026.
