Auriginal Mining outlines targets at Roger

Executive Summary

• Auriginal Mining Corp. developed a preliminary 3-D model of historical drill data at its Roger project, identifying new exploration targets and indicating significant resource upgrade potential.
• Geological modeling reveals historical copper-gold mineralization is truncated by a fault to the northeast (dropping ~200m) and remains open at depth below 350m, strongly supporting a volcanic-hosted massive sulphide (VMS) system model.
• The company has revised its upcoming diamond drill program based on these findings, with new drilling expected to commence in early March 2026.

Key Details

• Preliminary 3-D model developed using Leapfrog software to validate historical drill hole data and identify additional targets of opportunity.
• Historical copper-gold mineralization appears truncated northeast by a north-northwest fault, dropping the continuation by approximately 200 metres, indicating significant upgrade potential.
• Mineralization is not limited at depth, opening exploration potential below 350 metres.
• The thickest Roger zone aligns with the core of an interpreted volcanic dome or cryptodome, which serves as the required heat source for a VMS mineralizing system.
• Strongest geophysical targets are located on the southwestern and northeastern flanks of the interpreted dome structure, consistent with VMS systems.
• Recent geophysical results support the interpretation of a copper-zinc-gold-silver VMS system at Roger.
• Geological similarities reinforce parallels between the Roger project and Agnico Eagle's LaRonde mine in the southern Abitibi region.
• Longitudinal section data shows a significant thickening of the Roger mineralization along the interpreted volcanic dome axis.
• Alteration envelope characterizing the periphery of the Roger zone appears displaced vertically down by at least 200 metres on the east side of the interpreted fault.
• A strong borehole electromagnetic (BHEM) anomaly was detected in the northeast direction, believed to be related to massive base metal sulphide mineralization.
• Drill program revisions include adjustments to drill hole positioning and lengths based on the 3-D visualization work.
• New diamond drilling is expected to start in early March 2026.
