Quimbaya Gold Confirms Presence of a Copper-Molybdenum Porphyry System at Tahami Center

Potassic alteration and multiphase copper bearing porphyry veining intersected over 563 meters in TCDH-006, including 150 meters of intramineral porphyry. Assays pending.

Vancouver, British Columbia--(Newsfile Corp. - September 8, 2026) - Quimbaya Gold Inc. (CSE: QIM) (OTCQX: QIMGF) (FSE: K05) ("Quimbaya" or the "Company") reports geological results from its initial drill program at Tahami Center, part of the Company's Tahami Project in Segovia, Antioquia, Colombia. Six holes totaling 2,927.9 meters have been completed to date. All six holes intersected a copper-molybdenum porphyry system modelled from surface mapping and three-dimensional magnetic inversion. Assays are pending.

Highlights

Six holes totaling 2,927.9 meters were completed of a planned 5,000 meter program at Tahami Center.

All six holes intersected the copper-molybdenum porphyry system . Mineralization is variable between holes and, in places, marginal.

Potassic alteration with potassium feldspar, secondary biotite and magnetite is developed over approximately 563 meters in TCDH-006, from 96 meters to the bottom of the hole at 658.85 meters, including 150 meters of the principal intramineral porphyry between 294 and 444.40 meters.

Veinlet densities of up to 50 to 60 quartz, chalcopyrite and molybdenite veinlets per meter of core were logged in TCDH-006. All mineral identifications are visual and assays are pending.

TCDH-007 is collared and ready to drill on the same mineralized trend.

Assay results are expected in late September or October 2026.

Management Commentary

Alexandre P. Boivin, President and Chief Executive Officer, commented:

"We modelled this system from surface, and all six holes intersected the porphyry system as predicted by the exploration model. The drilling has given us the alteration zoning and the principal intramineral porphyry, which will help guide future drilling within the porphyry system. TCDH-007 is already collared on the trend this program defined. Assays are pending."

The Program

The program is designed to test the approximately 3.1 by 1.3 kilometer Tahami Center porphyry copper - molybdenum system as defined by surface mapping, soil and rock geochemistry, 3D Magnetic Vector Intensity modeling and Radiometric data. Six holes were drilled from four platforms between 21 May 2026 and 17 August 2026, for a total of 2,927.9 meters of a planned 5,000 meter program (Figure 1). End of hole depths were 294.30 meters (TCDH-001), 429.05 meters (TCDH-002), 602.25 meters (TCDH-003), 552.40 meters (TCDH-004), 391.05 meters (TCDH-005) and 658.85 meters (TCDH-006).

These initial drillholes were designed to establish whether a porphyry copper system is present, to map its architecture and alteration zoning, and to identify vectors toward the centers of mineralization for future drill testing. All six holes intersected the porphyry system. Five holes intersected intramineral porphyry, breccia and variable sulfide mineralization. TCDH-005 intersected crowded-texture intermineral porphyry from 137 meters to approximately 391 meters with high-temperature "B type" veinlets carrying chalcopyrite and molybdenite, and forms part of the same system, with mineralization in that hole visually estimated as marginal.

Potassic Alteration and the Intramineral Porphyry

TCDH-006 is the deepest hole of the program. It was drilled with an azimuth of 245 degrees at an inclination of -55 degrees, to a total depth of 658.85 meters (Figures 1 and 2).

Potassic alteration is present from approximately 96 meters to the end of the hole, a downhole interval of approximately 563 meters. The potassic assemblage comprises potassium feldspar with secondary biotite and magnetite, developed through that interval. The hole intersected the upper margin of the modelled potassic core, which remains open at depth and to the southeast (Figure 2).

Magmatic-hydrothermal breccia and intramineral porphyries were logged between 96 meters and 294 meters. From 294 meters to 444.40 meters the hole intersected fine-grained granodiorite porphyry of aplitic texture, the principal intramineral porphyry, with a high density of magnetite and chalcopyrite "M" veinlets, "A type" quartz veinlets and "EB type" veinlets containing secondary biotite and chalcopyrite. Sulfides within these veinlets comprise chalcopyrite, molybdenite and pyrite, estimated visually and not quantified. From 444.40 meters to the end of the hole, hydrothermal-magmatic breccias of the same igneous suite were logged (Figure 2).

Veinlet densities of up to 50 to 60 per linear meter were recorded. Chalcopyrite is present in the high-temperature "M", "A type" and "EB type" veinlets, and "EDM type" veinlets with biotite halos carry molybdenite (Figures 3 and 4).

The Company cautions that the intervals described in this news release are alteration and lithological intervals. They are not mineralized intervals, they are not assay intervals, and no grades are available for any part of the program.

TCDH-001 to TCDH-005

Drill hole TCDH-001 recorded the following zonation: a leached and oxidized cap containing hematite, hydrothermal cemented breccia, magmatic-hydrothermal breccia, intramineral aplitic granodiorite porphyry, and a potassic core of secondary biotite and magnetite. The hydrothermal breccia is cemented by silica, white mica and pyrite assemblage with minor chalcopyrite. At 278 meters the hole intersected aplitic-textured granodiorite porphyry carrying chalcopyrite and bornite. The hole was terminated at 294.30 meters due to poor ground conditions and ended in intramineral porphyry. Anhydrite occurs within multiple hydrothermal alteration assemblages.

TCDH-002 and TCDH-003 intersected hydrothermal and hydrothermal-magmatic breccias together with intramineral porphyries, secondary biotite and magnetite alteration, and quartz veinlet stockwork carrying variable chalcopyrite and molybdenite (Figure 5). TCDH-004 intersected chilled-texture intramineral porphyry with disseminated chalcopyrite and pyrite, "A type" veinlets and "EDM type" veinlets, with secondary biotite and anhydrite halo.

TCDH-005 intersected crowded-texture intermineral porphyry from 137 meters to approximately 391 meters, with secondary biotite and magnetite alteration and high-temperature "B type" veinlets carrying chalcopyrite and molybdenite. The hole forms part of the same porphyry system, with mineralization visually estimated as marginal.

Next Steps

The porphyry system is controlled by a northwest to southeast structural trend associated with multiple porphyry intrusions. Based on current drill results, the mineralized trend defined by this drilling constitutes the most prospective target identified to date for additional mineralized porphyry centers (Figure 1).

TCDH-007 has been collared approximately 410 meters northeast of TCDH-006, and will be drilled to a planned depth of 300 meters.

Assay results from the initial six holes are expected in late September or October 2026.

Sampling and Quality Control

Drill core was logged and photographed by Company personnel under the supervision of the Qualified Person. Core samples were collected from half core intervals in HQ3 and NQ3 drill core over two meter sample lengths, with cuts oriented as close as possible to perpendicular to the observed structural fabric. Sample weights typically ranged from approximately two to three kilograms. Samples have been submitted to SGS, an ISO 17025 accredited laboratory independent of the Company.

Quimbaya has implemented a quality assurance and quality control program that includes the regular insertion of certified reference materials, blanks and field duplicates into the sample stream at an approximate rate of 15 to 20%. No analytical results have been received and none are reported in this news release. Sample preparation, analytical methods, detection limits and the quality control results for the program will be disclosed together with the assay results.
