Rockland identifies 4.5 km gold corridor at Cole mine

Executive Summary

• Rockland Resources identified a new 4.5-kilometre-long gold corridor at its Cole Gold Mine property in the Red Lake Mining District, Ontario, based on its 2025 prospecting program.
• The new target is an untested ultramafic-felsic volcanic contact within the Pipestone Bay deformation zone, which aligns with the geological model of major regional gold deposits like Great Bear Dixie.
• A historic drill hole (Hole 12) intersected 3.7 metres of visible gold in quartz-carbonate veining along this contact, validating the need for further diamond drilling to assess the district-scale potential.

Key Details

• New Target Identification: A 4.5 km strike length of gold mineralization interpreted along an ultramafic-felsic volcanic contact within the Pipestone Bay deformation zone.
• Geological Context: The corridor lies along two key lithologic boundaries: a previously underexplored ultramafic-felsic contact (including segments under shallow lake cover) and the diorite-felsic volcanic contact hosting historic mine workings.
• Historic Drill Data: Historic drill hole 12, which tested the ultramafic-felsic volcanic contact zone, yielded a 3.7-metre intercept containing visible gold in quartz-carbonate veining.
• Regional Correlation: The geological setting is directly comparable to the Great Bear Dixie project (Kinross), where high-grade gold mineralization occurs along felsic-ultramafic contacts within a major deformation corridor.
• Strategic Significance: The discovery validates the geological model linking Cole to the Pipestone corridor that controls gold at the Rowan and Mount Jamie occurrences.
• Future Plans: The company intends to advance to targeted drilling along the ultramafic contact and further evaluate the diorite-felsic zone along strike and at depth to determine continuity of the gold system.
• Assay Status: Assay results from the 2025 prospecting program will be released as they become available.

Notable Quotes

• "The recognition of the ultramafic-felsic volcanic contact zone as a favourable site for gold mineralization significantly enhances the scale and potential of the Cole project... With historical production from the diorite zones and an entirely untested ultramafic target beneath lake cover, we now view Cole as a district-scale gold opportunity ready for the drill phase." — Mike England, Chief Executive Officer
