TSX Index: Radisson Mining Uncovers Surface Gold Near O’Brien Project

Highlights

• Radisson Mining has discovered coarse visible gold in a surface trench at the O'Brien Gold Project in Quebec.
• The trench, located thirty metres from the O'Brien core shack, lies near the surface projection of the historic Jewellery Box zone.
• This new surface discovery is part of Radisson's broader summer exploration strategy targeting high-grade quartz-sulphide-gold veins.

The gold exploration sector in Canada, particularly in the Abitibi greenstone belt of Quebec, is anchored by several junior miners listed on the TSX Venture Exchange. Companies such as Radisson Mining Resources Inc. (TSXV:RDS) contribute to the momentum of the sector. Radisson’s latest development at its 100%-owned O’Brien Gold Project, located near Rouyn-Noranda, underscores ongoing mineralization efforts in the region. The discovery aligns with activity monitored under indexes like the tsx index, which reflects market engagement across resource exploration companies.

Visible Gold Discovery in New Surface Trench

Radisson Mining has uncovered a new occurrence of coarse visible gold within a surface trench labeled OB-25-TR001. The trench was excavated only thirty metres east of the O’Brien project's core shack and operational buildings. It is situated in proximity to the surface projection of the historically productive Jewellery Box zone. The exposed mineralization comprises quartz-sulphide-gold veins hosted in Piché Group rocks.

This trench marks the first in a series scheduled for the summer fieldwork campaign. The strategic intent behind the trenching effort is to analyze the structural behavior and continuity of the quartz-vein systems associated with the Cadillac-Larder Lake Break. The discovery, made under shallow overburden, illustrates the regional geology's ongoing gold-bearing potential.

Connection to the Jewellery Box Zone

The trench’s location is close to the interpreted surface trace of the Jewellery Box zone, a known vertical and narrow stope from the former O'Brien Gold Mine. Historically, this area has yielded some of the highest grades within the deposit. The Jewellery Box gained recognition for high-grade ore and visually striking gold samples often deemed museum-quality.

In December of the previous year, drilling efforts confirmed the likely rediscovery of this zone at depth. A prior intercept had returned exceptionally high-grade results at around 200 metres vertical depth. The current surface trench lies outside the bounds of the previously published mineral resource estimates and the recently completed Preliminary Economic Assessment (PEA). Nonetheless, the trench’s proximity to the Jewellery Box underpins Radisson’s decision to conduct continued surface evaluations in this sector.

Trenching Strategy and Exploration Progress

The summer exploration program is advancing with a focus on refining geological interpretations of the quartz-sulphide vein structures. Trenching is being applied as a surface method to provide direct exposure to the rock units within the hanging-wall of the Cadillac-Larder Lake Break. This geological break has long been associated with gold mineralization across the Abitibi region.

By initiating the trenching campaign near existing infrastructure, Radisson intends to build geological context while maintaining cost efficiency. The exposure of visible gold in the first trench is considered a notable development, especially given the ease of access and the shallow nature of the overburden.

Further trenching is planned across adjacent zones that share similar geological features. All active and future trenching sites have been secured to restrict unauthorized entry and ensure controlled data collection.

Implications for Broader Regional Mineralization

The Abitibi region continues to be a critical area for gold exploration in Canada due to its prolific greenstone geology. Discoveries such as the one announced by Radisson reflect the enduring capacity of the region to yield new zones of mineralization, even near previously explored or historically mined areas.

Radisson’s project area encompasses parts of the Piché Group and other lithological formations often associated with high-grade deposits. The ability to identify coarse visible gold at surface, especially within known structural corridors, enhances the understanding of mineral distribution in the immediate vicinity of the O'Brien project.

This surface discovery not only confirms earlier geological interpretations but also supports continued exploration along the corridor extending from the historic workings. While no updates to resource estimates or economic assessments have been released in connection with this trenching, the field program remains active, with additional results anticipated through the remainder of the exploration season.
