Quimbaya completes surveys covering Tahami Center

Executive Summary

• Quimbaya Gold Inc. has completed drone-based magnetic and radiometric surveys covering approximately 800 hectares at its Tahami Center concession, expanding the copper porphyry target to a 3.1 km by 1.3 km trend.
• The survey identified high magnetization vector intensity (MVI) anomalies interpreted as subvertical porphyry intrusions, coinciding with surface potassic alteration and anomalous copper, gold, and molybdenum geochemistry.
• A lithocap zone was identified in the southeastern portion, characterized by low magnetic susceptibility due to magnetite-destructive advanced argillic alteration, which is locally associated with quartz vein systems containing gold, silver, and copper.

Key Details

• Survey Scope: Drone-based magnetic and radiometric surveys completed over ~800 hectares of the Tahami Center concession.
• Target Expansion: The prospective surface trend for the porphyry-style copper system has been expanded to approximately 3.1 km in length by 1.3 km in width, with a dominant northwestern-southeastern orientation.
• Geophysical Findings:
  • High MVI anomalies indicate two subvertical zones dipping to the southeast, interpreted as porphyry intrusions.
  • These intrusions coincide with mapped porphyry-style potassic alteration and veining showing anomalous copper, gold, and molybdenum.
  • An MVI low anomaly on the southeastern side coincides with a mapped lithocap where alteration is magnetite-destructive.
• Geological Interpretations:
  • Magnetic anomalies are interpreted to be associated with a porphyry intrusive suite.
  • Detailed geological mapping identified a preserved lithocap in the eastern-southeastern portion of the concession.
  • This lithocap zone spatially coincides with low magnetic susceptibility values, interpreted as magnetite destruction from intense advanced argillic alteration.
  • This alteration zone is locally associated with quartz vein systems where surface sampling has identified gold, silver, and copper mineralization.
• Next Steps: Pad locations for the maiden drilling program will be defined after integrating soil, rock, and stream sediment geochemical assay results, detailed geological mapping, and preliminary 3-D geological-geophysical modelling. This work is expected to be finalized within the current month.
• Disclaimer: The interpretation of magnetic anomalies reflecting zones of increased magnetite content associated with potassic alteration is conceptual and has not yet been confirmed by drilling.

Notable Quotes

• "The work completed to date at Tahami continues to strengthen our confidence in the exploration potential of the project... This survey materially strengthens our technical thesis at Tahami Center. We are seeing a large, coherent subsurface magnetic system that aligns with mapped surface mineralization and alteration. That level of consistency supports advancing confidently toward drill testing as we define our initial targets." — Alexandre P. Boivin, CEO
• "The presence of well-developed porphyry-style veinlets at surface is considered significant in the context of the company's exploration model for a porphyry copper-gold-molybdenum system... These magnetic anomalies may reflect zones of increased magnetite content, which in porphyry systems can be associated with potassic alteration. This interpretation is conceptual in nature and has not yet been confirmed by drilling." — Ricardo Sierra, VP, Exploration
