Quimbaya Gold Confirms Discovery of Two Mineralized Vein Structures at Tahami South, Colombia

Mineralization intersected in 8 of 9 holes at Tahami South, directly adjacent to Aris Mining’s producing operations in the Segovia gold district

Quimbaya Gold Inc. (CSE: QIM,OTC:QIMGF) (OTCQB: QIMGF) (FSE: K05) (‘Quimbaya’ or the ‘Company’) is pleased to announce the discovery of two new mineralized vein systems at its 100%-owned Tahami South Project in the Segovia-Remedios gold district of Antioquia, Colombia.

The Company’s ongoing drill program at Tahami South has successfully identified vein systems that include the previously targeted Vein S and Vein V, confirming the presence of mineralization consistent with quartz vein systems mined regionally. These results confirm the continuation of the Segovia district’s geological architecture onto Quimbaya’s ground, a core thesis of the Company’s strategy.

‘This is a milestone event for Quimbaya. These first vein discoveries validate our thesis and represent a turning point as we move from land assembly into value creation through the drill bit,’ said Alexandre P. Boivin, CEO of Quimbaya Gold. ‘They are not just promising results, they are proof that we’re on to a significant mineralized system, with the grades, geometry, and geology that define Colombia’s most productive gold district.’

Discovery Highlights

• Several Veins intersected across multiple drill platforms

• Mineralization intersected in 8 out of 9 drill holes, demonstrating strong structural continuity and robust targeting accuracy in the inaugural Phase 1 program.

• Drilling remains ongoing, with over 4,000 meters completed to date; the program has been extended beyond its initial scope in response to encouraging early results.

• Two distinct vein structures system (S & V) discovered, confirming Segovia-style mineral continuity on Quimbaya’s ground.

• Mineralization comprises quartz, barite, carbonate veining with sulphide assemblage (pyrite, chalcopyrite, galena, sphalerite).

‘These intercepts confirm that we are tapping into the same geological architecture that has made the Segovia district one of the most prolific gold producers in Latin America,’ said Ricardo Sierra, B.Sc., AusIMM, VP Exploration. ‘We see clear continuity in structure, mineralogy, grade, and believe we are only beginning to uncover the full potential at Tahami South.’

While initial assay results have been received from select drill holes, the Company is continuing to await the return of a significant portion of its Phase 1 drill campaign. In the interest of providing a more complete and technically coherent picture of the emerging discovery at Tahami South, Quimbaya intends to release assay data once a critical mass of results has been compiled. This approach ensures a balanced and contextualized interpretation of both grade distribution and structural continuity, and reflects the Company’s commitment to disciplined, data-driven disclosure as the scale of the system comes into focus.

Strategic Implications: Thesis Confirmed

The discovery of vein systems that include the previously targeted Veins S and V represents the first clear technical validation of Quimbaya’s exploration thesis: that district-scale mineralized structures extend beyond known mines into underexplored ground. The Company’s focused land acquisition strategy prioritized claims with gold & silver+ at surface and proximity to producers, and now, early drilling confirms this model is working.

With over 4,000 meters already drilled, surpassing the originally planned Phase 1 total, the Company has extended its current program to follow up on promising early results and to further evaluate vein continuity at depth and along strike. The strong correlation between drill intercepts and the geological model has reinforced Quimbaya’s exploration thesis. These results not only validate the presence of a robust mineralized system but also provide clear vectors for systematic expansion drilling in 2026.
