QUIMBAYA GOLD ANNOUNCES THAT DR. STEWART REDWOOD PROVIDES INDEPENDENT CONFIRMATION OF PORPHYRY COPPER SYSTEM AT TAHAMI CENTER

Dr. Stewart D. Redwood, an independent consulting economic geologist with over 40 years of experience specializing in porphyry copper systems across Latin America, has completed a site visit to Quimbaya Gold Inc.'s Tahami Center project and provided independent confirmation of a large porphyry copper-gold-molybdenum system.

Dr. Redwood's field examination, conducted Nov. 6 to Nov. 8, 2025, confirms that Tahami Center is a porphyry system measuring approximately 2.0 kilometres north-south by 1.4 km east-west based on current mapping. The system remains open in all directions. It exhibits complete alteration zonation from potassic core through phyllic envelope to advanced argillic lithocap -- the classic textbook porphyry model.

Dr. Redwood states this discovery "changes the metallogenic picture" of the Segovia district, which has historically been known for high-grade gold veins rather than porphyry copper-gold-molybdenum systems. He recommends that the company fast track exploration to define drill targets for Q2 2026.

Why this matters

• Porphyry systems host the world's largest copper-gold deposits;
• Peru's Toquepala, Cuajone, Quellaveco -- with the same geological setting -- are among the world's major copper producers;
• Complete alteration zonation visible at surface indicates a well-preserved system;
• Q2 2026 drilling will be the first drill test of this system.

Highlights

• "Field observations confirm that it is an extensive porphyry copper system;"
• "This changes the metallogenic picture and opens up exciting new exploration potential;"
• "A bonus discovery - now gives two different types of targets at Tahami: Au-Ag veins and Cu-Au-Mo porphyry;"
• Recommends fast-track exploration to define drill targets for Q2 2026.

Porphyry copper system characteristics:

• Complete alteration zonation: potassic core "phyllic envelope" advanced argillic lithocap;
• Full porphyry veinlet sequence observed (A/M/B-type and D-type veins);
• Highly anomalous Cu (copper), Au (gold), Mo (molybdenum), Pb (lead) and Zn (zinc) in channel sampling;
• Strong positive magnetic anomaly coincident with porphyry copper system.

Dr. Stewart Redwood statement

Dr. Redwood, BSc (honours), PhD, FIMMM, FGS, stated:

"Field observations confirm that it is a porphyry copper system. This is a bonus discovery and now gives two different types of targets at Tahami -- Au-Ag veins and porphyry Cu-Au-Mo -- and two commodities of copper as well as gold. I recommend that the company fast track exploration to define drill targets for Q2 2026.

"The discovery of a porphyry system in the Segovia district is a first. The district is well known for high-grade gold veins. It changes the metallogenic picture and opens up exciting new exploration potential in Quimbaya's extensive Tahami project.

"An analogy can be made with the geological setting of the porphyry Cu-Mo deposits of southern Peru -- Toquepala, Cuajone and Quellaveco. They formed on the southern continuation of the same continental margin magmatic arc. The porphyries are hosted by basement metamorphic rocks, the coastal batholith, which is equivalent to the Segovia batholith, and porphyry stocks which are much younger than the batholith -- exactly what we're seeing at Tahami Center."

Management commentary

Alexandre P. Boivin, president and chief executive officer, commented:

"Dr. Redwood has confirmed what our team suspected, we have a genuine porphyry copper-gold-molybdenum system at Tahami Center. This changes the exploration picture for Quimbaya. We now have two distinct deposit types at Tahami: the high-grade veins we have been drilling at Tahami South, and a 2.0-by-1.4-kilometre porphyry system that remains open in all directions. We are mobilizing to execute Dr. Redwood's recommended work program and expect to have drills turning at Tahami Center in Q2 2026. Channel sampling and ridge-and-spur soil sampling are being completed and the results will be released when all of the analyses are received."

Two -- target exploration strategy

The Tahami Center porphyry emerged from systematic exploration across Quimbaya's 66,000-plus-hectare land package. As Dr. Redwood states, this is a "bonus discovery" -- the company is not pivoting away from its vein-hosted gold program at Tahami South.

• Tahami South (vein targets): Drill program targeting high-grade gold veins. Partial assay results pending. Near-term focus.
• Tahami Center (porphyry target): Predrill work program Q1 2026; maiden drilling Q2 2026.

Upcoming catalysts:

• Tahami Center geochemistry, soils sampling program and drill target definition (Q1 2026);
• Tahami Center maiden drilling (Q2 2026);
• Tahami South magnetic and IP ground geophysical survey (Q1 2026);
• Tahami South start of second drilling program (Q2 2026).

Technical summary

Dr. Redwood's field examination documented the complete suite of characteristics that define a porphyry copper-gold system:

• Potassic core: A/EB/B-type quartz veinlets in stockwork and sheeted style with secondary biotite, magnetite and potassium feldspar;
• Phyllic envelope: quartz-sericite alteration with D-type quartz veins (10 to 20 centimetres) containing pyrite, chalcopyrite, magnetite, molybdenite;
• Advanced argillic lithocap: terraspec-confirmed alunite, kaolinite, dickite, diaspore, pyrophyllite and kaolinite occur in a broad structural zone interpreted to be the root of the lithocap;
• Surface geochemistry: the preliminary results of channel sampling return highly anomalous values of Cu (copper), Au (gold), Mo (molybdenum), Pb (lead), Zn (zinc);
• Geophysics: strong high magnetic anomaly coincident with porphyry system.
