Quimbaya Gold drills 1 m of 9.8 g/t AuEq at Tahami

Executive Summary

• Quimbaya Gold Inc. released assay results from its inaugural diamond drilling program at the Tahami South target within its 100%-owned Tahami project in the Segovia-Remedios gold district of Antioquia, Colombia.
• The results confirmed high-grade silver and gold mineralization across two distinct vein systems (Vein S and Vein V), with significant intercepts including up to 17 oz/t Ag and 2.57 g/t Au.
• The Phase 1 program consisted of 5,320 metres in 12 holes; assays for eight holes (4,033 metres) have been received, showing widespread distribution of target structures across a 2.2-kilometre north-south extent.

Key Details

• Vein S Intercept 1: 1.0 metre at 9.8 g/t AuEq from 462.6 m depth, comprising 0.77 g/t Au and 528 g/t Ag (17 oz/t Ag). Described as a silver-dominant system with high-grade mineralization.
• Vein S Intercept 2: 0.9 metre at 9.0 g/t AuEq from 362.9 m depth, comprising 2.57 g/t Au and 378.1 g/t Ag (12.16 oz/t Ag). Described as a gold-silver system without polymetallic credits.
• Vein V Intercept: 0.9 metre at 3.0 g/t AuEq from 157.1 m depth, comprising 1.03 g/t Au and 113.2 g/t Ag. This intercept confirms structural continuity at depth over a 0.8 kilometre along-strike distance.
• Drilling Statistics: Phase 1 comprised 5,320 metres in 12 diamond drill holes from seven platforms. Assays received for eight holes totaling 4,033 metres; results for four holes (1,287 metres) are pending.
• Geological Context: Visual mineralization has been traced 1.6 kilometres along strike for Vein S. Mineralized vein intercepts were returned from five of seven platforms tested, demonstrating widespread distribution across a 2.2-kilometre north-south extent.
• Vein Characteristics:
  • Vein S: Striking NNE/SSW, hosting silver-dominant mineralization. The 528 g/t Ag intercept in hole TSDH_007 is the highest-grade silver intersection reported to date for the project. Mineralization includes quartz-carbonate veining with galena and associated sulphides.
  • Vein V: Striking NE-SW, carrying a gold-silver-lead-zinc assemblage. Intercepts in TSDH_008 and TSDH_004 confirm continuity. The polymetallic signature (including anomalous zinc up to 0.20%) is consistent with intermediate-sulphidation epithermal vein systems.
• Gold Equivalent Calculation: AuEq g/t = Au g/t + [Ag g/t × (Ag price / Au price)]. Metal prices used: Gold $4,400/oz, Silver $75/oz (spot prices as of January 2026). Base metal credits (Pb, Zn) are excluded from AuEq calculations.
• Laboratory and QA/QC: Samples analyzed by SGS Peru (ISO-accredited) using fire assay (Au) and AAS methods (Ag, base metals). Preparation occurred in Medellin, Colombia. QA/QC protocols included certified reference materials, blanks, and field duplicates with an insertion rate of 16%.

Notable Quotes

• "Tahami South has delivered on its promise... Two distinct vein systems, high-grade silver and gold at up to 17 oz/t Ag and 2.57 g/t Au, and structural continuity over 1.6 and 2.2 kilometres -- all in our inaugural drill campaign. We now have the geological confidence to advance systematically while our attention turns to the district's larger targets." — Alexandre P. Boivin, CEO
• "The silver is not incidental -- it's telling us something about the system... The grades we are seeing confirm we have intersected the right structures." — Ricardo Sierra, VP of Exploration
