Quimbaya Gold Identifies New Gold Target At Tahami Southeast with Rock Samples Up to 59.4 G/T Au and 52.30 G/T Ag
Quimbaya Gold Inc. has defined a new gold exploration target at Tahami Southeast, in the southern portion of the Company's district-scale land package in Colombia's Segovia Gold District — immediately adjacent to Aris Mining's high-grade gold operations. Initial field work returned rock (grab and panel-grab) sample assays of up to 59.4 g/t gold and 52.30 g/t silver from quartz vein sub-outcrops. Up to 59.4 g/t gold and 52.30 g/t silver in rock (grab and panel-grab) samples from quartz vein sub-outcrops with galena and sphalerite — selective samples, not necessarily representative of the property. Tahami Southeast sits on Quimbaya's district-scale ground in Colombia's Segovia Gold District. New ~1 km × 1 km target — a sericitic-alteration color anomaly, open in several directions, with sub-outcrops of quartz veins and visible gold in pan. Third target on the trend — after the Tahami South veins (December 2025) and the Tahami Center Cu-Mo-Au porphyry. Next — mapping and sampling to define drill targets, planned for the second half of 2026. Tahami Southeast lies in the southern portion of Quimbaya's land package in Colombia's Segovia Gold District, immediately adjacent to Aris Mining's high-grade gold operations. Initial geological mapping and prospecting have identified at least two prospecting areas, including quartz vein sub-outcrops with gold-silver high grade confirmed by gold in pan downstream; and quartz veins hosted in porphyritic granodiorite with strong sericite alteration and high gold concentration in pan. Selective grab and panel-grab sampling target sub-outcrops returned assays of up to 59.4 g/t gold and 52.30 g/t Ag. Grab and panel-grab samples are selective by nature and are not necessarily representative of the mineralization on the property. The second target is defined by an approximately one square kilometer color anomaly, interpreted as strong sericitic alteration, that remains open in several directions, with coarse gold in pan observed in the surrounding drainages. Two principal vein trends have been mapped: a northeast trend, associated with the historic Mina Antigua and El Chicharrón workings, and a northwest trend. Active and abandoned artisanal workings within the area are under investigation. The historic Mina Antigua and El Chicharrón workings, the Guía Antigua and Chicharrón mines, and the Aris Mining operations referred to in this news release are located on properties not held by the Company; the Qualified Person has not verified the exploration information from those adjacent properties, and such information is not necessarily indicative of the mineralization at Tahami Southeast. Currently, exploration continues to advance towards the southeast of the claim. The Segovia Gold District has produced gold for over a century and hosts Aris Mining's high-grade operations. The structurally-controlled quartz veins with galena and sphalerite identified at Tahami Southeast are characteristic of the epithermal vein systems that define the district. This geological setting is provided as technical context only and is not a representation that similar results will be achieved at Tahami Southeast.

District-scale location map showing Tahami Southeast relative to Aris Mining's Segovia operations and Quimbaya's Tahami Project. The Company intends to advance Tahami Southeast through systematic geological mapping, rock and channel sampling, and structural interpretation to define drill targets. This program is planned for the second half of 2026. Results will be reported as they are received and verified by the qualified person. Samples were collected by Company personnel under the supervision of the qualified person, with locations recorded by handheld GPS. Rock and stream-sediment samples were submitted to SGS, an ISO/IEC 17025-accredited laboratory independent of the Company. The rock results reported herein are from selective grab samples, which are not necessarily representative of the mineralization on the property. All samples were prepared and analyzed by SGS laboratories in Medellín, Colombia, and Lima, Peru. SGS Colombia and SGS Peru are ISO 17025-accredited and are independent of the Company. Gold assays were completed using fire assay methods, with multi-element analysis conducted using ICP techniques. Gold was determined by fire assay on a 30 g charge with an atomic absorption finish (SGS method code FAA313); multi-element analysis, including silver, was conducted by four-acid digestion with ICP-AES/ICP-MS finish (SGS method code ICP40B). Over-range copper assays above the upper detection limit of 1% Cu were re-analysed by ore-grade assay methods (SGS code AAS41B). Detection limits for the primary elements were Cu 0.5 ppm, Mo 1 ppm, Au 5 ppb, Pb 2 ppm, and Zn 0.5 ppm. The analytical protocols used are industry-standard for this style of vein-hosted gold-silver mineralization and are considered appropriate for the style and grade of the samples collected. Quimbaya implemented a quality assurance and quality control (QA/QC) program that included the regular insertion of certified reference materials, blanks, and field duplicates. Control samples were inserted at an approximate rate of 15-20% throughout the sampling program. QA/QC results were reviewed by the Company's Qualified Person and are considered acceptable, supporting the reliability of the analytical data. Certified reference materials (CRMs) used included (Epi-35, Epi-41 of Target rock certificates) covering the expected grade range for Cu, Ag, and Au. CRMs returned values within ±2 standard deviations of their certified means. Coarse blank material sourced from Bureau Veritas quartz certificates returned values below 10x the detection limit for all elements of interest. Field duplicates showed an average pair correlation of R²= 0.872, within industry-accepted tolerances. Channel samples were collected as continuous chip channels cut perpendicular to the observed structural orientation within underground workings at the Laurel mine and surface outcrops. Channel dimensions were approximately 15 cm wide up to 2m. Ricardo Sierra, AusIMM, is a non-independent Officer "VP Exploration" and the Qualified Person for this news release.
