Quimbaya Gold confirms Tahami porphyry system

Executive Summary

• Quimbaya Gold Inc. announced that independent consulting geologist Dr. Stewart Redwood has confirmed the existence of a large porphyry copper-gold-molybdenum system at the Tahami Center project in Colombia.
• The system measures approximately 2.0 km by 1.4 km and exhibits complete alteration zonation (potassic core to advanced argillic lithocap), indicating a well-preserved porphyry model similar to major Peruvian deposits like Toquepala and Quellaveco.
• Management plans to fast-track exploration, with pre-drill work scheduled for Q1 2026 and maiden drilling at Tahami Center targeted for Q2 2026, while maintaining parallel exploration at Tahami South.

Key Details

• System Dimensions: The porphyry system measures approximately 2.0 kilometres north-south by 1.4 km east-west based on current mapping and remains open in all directions.
• Geological Characteristics:
  • Complete alteration zonation observed: Potassic core, phyllic envelope, and advanced argillic lithocap.
  • Porphyry veinlet sequence observed, including A/M/B-type and D-type veins.
  • Strong positive magnetic anomaly coincident with the system.
• Geochemistry: Channel sampling returned highly anomalous values for Copper (Cu), Gold (Au), Molybdenum (Mo), Lead (Pb), and Zinc (Zn).
• Strategic Impact: The discovery adds a second deposit type (Cu-Au-Mo porphyry) to the existing high-grade Au-Ag vein targets at Tahami South, diversifying the project's potential.
• Exploration Schedule:
  • Q1 2026: Completion of channel sampling, ridge-and-spur soil sampling, and drill target definition for Tahami Center; Magnetic and IP ground geophysical survey for Tahami South.
  • Q2 2026: Maiden drilling at Tahami Center; Start of second drilling program at Tahami South.
• Analogy: Dr. Redwood noted the geological setting is analogous to the southern Peruvian continental margin magmatic arc, hosting deposits like Toquepala, Cuajone, and Quellaveco.

Notable Quotes

• Dr. Stewart Redwood (Independent Consulting Economic Geologist): "Field observations confirm that it is an extensive porphyry copper system... This changes the metallogenic picture and opens up exciting new exploration potential... I recommend that the company fast track exploration to define drill targets for Q2 2026."
• Alexandre P. Boivin (President and CEO): "Dr. Redwood has confirmed what our team suspected, we have a genuine porphyry copper-gold-molybdenum system at Tahami Center. This changes the exploration picture for Quimbaya... We are mobilizing to execute Dr. Redwood's recommended work program and expect to have drills turning at Tahami Center in Q2 2026."
