Quimbaya Gold Expands Copper Porphyry Target to 3.1km After Airborne Geophysics Survey

Executive Summary

• Quimbaya Gold completed drone‑based magnetic and radiometric surveys over ~800 ha of the Tahami Center concession, identifying extensive magnetization vector intensity (MVI) anomalies consistent with a porphyry‑style copper‑gold‑molybdenum system.
• Two sub‑vertical high‑magnetization zones dip southeast and align with surface potassic alteration and anomalous Cu, Au, Mo geochemistry; a low‑magnetization zone coincides with a mapped lithocap showing advanced argillic alteration.
• The company will define pad locations for its maiden drilling program later this month after integrating pending soil, rock, stream sediment assays, detailed mapping, and 3‑D modeling.

Key Details

• Survey area: ~800 ha covering a prospective surface trend of ~3.1 km × 1.3 km.
• High MVI anomalies indicate two sub‑vertical zones interpreted as porphyry intrusions; they align with mapped potassic alteration and vein systems.
• A low MVI anomaly on the SE side matches a lithocap where magnetite destruction is evident, suggesting intense advanced argillic alteration associated with Au‑Ag‑Cu mineralization.
• Magnetic anomalies extend ~3.1 km (length) by ~1.3 km (width) with a dominant NW‑SE orientation.
• Pad locations for the initial drilling program will be set after:
• Completion and integration of soil, rock, and stream sediment geochemical assay results.
• Detailed geological mapping.
• Preliminary 3‑D geological‑geophysical modeling (expected to be finalized this month).
• CEO Alexandre P. Boivin states the survey “materially strengthens our technical thesis at Tahami Center” and supports advancing toward drill testing.
• VP Exploration Ricardo Sierra notes that the magnetic high may reflect zones of increased magnetite content linked to potassic alteration, but emphasizes that confirmation requires diamond drilling.

Notable Quotes

“The work completed to date at Tahami continues to strengthen our confidence in the exploration potential of the project,” – Alexandre P. Boivin, CEO
“The presence of well‑developed porphyry‑style veinlets at surface is considered significant… These magnetic anomalies may reflect zones of increased magnetite content, which in porphyry systems can be associated with potassic alteration.” – Ricardo Sierra, VP Exploration & Qualified Person
