Andina Copper Exploration Update: Progress and Strategic Advancements at Cobrasco

January 22, 2026 – Andina Copper Corporation (TSX-V: ANDC | FSE: FIR | OTCQB: PMMCF) today released a comprehensive update on its ongoing exploration activities at the Cobrasco copper project, located in the Chocó Department of Colombia. This latest press release provides detailed insights into the significant progress made during the 2025–2026 exploration season, including drilling results, surface sampling programs, advanced geophysical surveys, and the Company’s strategic efforts to delineate what could be a major copper deposit on its property.

Overview of Cobrasco Exploration Program

The Cobrasco project represents one of Andina Copper’s flagship exploration assets. Since fieldwork commenced in early October 2025, the Company has rapidly advanced reconnaissance mapping, rock chip sampling, and diamond drilling at the central target zone known as Cobrasco Central. In addition to drilling, surface exploration programs have been extended into the Cobrasco East area with comprehensive sampling and prospecting activities.

Significant Drilling Results

To date, Andina Copper has completed over 2,000 meters of diamond drilling across three holes at Cobrasco Central. The results include wide intervals of copper and molybdenum mineralization, consistent with porphyry-style systems. Highlights of the drilling include:

• CDH001: 808 m @ 0.42% Cu and 79 ppm Mo from 184 – 992 m
• CDH002: 754 m @ 0.46% Cu and 76 ppm Mo from 152 – 906 m
• CDH003: 144.6 m @ 0.69% Cu, 155 ppm Mo, and 1.4 g/t Ag from 156 – 300.6 m (End of Hole)

These intervals, particularly in CDH003, show encouraging mineralization that remains open at depth and along strike, supporting the Company’s hypothesis of a sizeable porphyry system. Assays from the recently completed continuation of CDH003 to a final depth of 774.80 m are anticipated soon.

Understanding the Geological Context

The drill holes to date have encountered broad zones of copper-molybdenum mineralization typical of porphyry systems. Previous work by Rugby Resources revealed that the final 2.6 meters of CDH003 ended with particularly high copper and silver values, underscoring the potential of the system. This mineralization style often forms large, disseminated deposits that can be significant sources of copper and other metals.

Surface Exploration and Geophysical Surveys

Cobrasco East Prospect Work

In addition to drilling, Andina Copper has advanced surface exploration at the Cobrasco East target area. Programs include:

• Stream sediment sampling to detect anomalous copper and molybdenum values
• Rock chip sampling to identify localized mineralization in outcrop and float samples
• Reconnaissance geological mapping to better understand structural and lithological controls on mineralization

These efforts have helped refine drill targets and identify new areas of interest for future campaigns.

Use of Advanced Survey Technologies

Andina Copper is also deploying modern geoscience technologies to enhance its geological understanding of Cobrasco. The Company has initiated a drone LiDAR and aerial photogrammetry survey, which provides high-resolution topographical data, improving mapping accuracy and target definition. This cutting-edge approach gives geologists an aerial perspective of surface features and structural trends that might control mineralization.

Furthermore, preparations are underway for deep geophysical surveys, including:

• Airborne Magnetotelluric (AirMT): A technique that measures variations in the Earth’s natural electromagnetic fields to identify subsurface conductivity contrasts, which can indicate mineralized bodies.
• Ground-Based Induced Polarization (IP): A powerful geophysical method that helps detect disseminated sulfide mineralization often associated with porphyry copper systems.

These surveys are expected to considerably sharpen drill targeting and lead to further discoveries on the property.

Strategic Importance for Andina Copper

Cobrasco is a strategic asset within Andina Copper’s portfolio, which also includes other promising targets across South America. The Company’s efforts at Cobrasco are part of a broader exploration strategy aimed at rapidly advancing high-potential projects. In recent months, Andina has also been active on other fronts, such as accelerating drilling at Piuquenes in Argentina and reporting high-grade rock chip results from the Mantau project in Chile. These collective efforts underscore a catalyst-rich period for the Company’s exploration pipeline.

Market Position and Corporate Milestones

Andina Copper’s exploration advances coincide with significant corporate developments. Notably, the Company’s common shares commenced trading on the TSX Venture Exchange (TSX-V: ANDC) in late 2025, marking an important milestone that reflects investor interest in its copper exploration projects across South America.

With multiple projects in various stages of exploration and a growing news flow, Andina Copper is poised to deliver further updates as assay results from recent drilling become available and geophysical interpretation progresses. Continued success at Cobrasco could materially enhance the Company’s resource potential and long-term value proposition.

Next Steps and Outlook

Looking ahead, Andina Copper plans to:

• Release assay results from the latest drilling at Cobrasco Central
• Complete advanced geophysical surveys to define deeper and broader targets
• Continue surface sampling and geological mapping across the exploration concession
• Integrate all data sets to prioritize future drilling targets

The Company anticipates that ongoing exploration activities will provide critical insights into the scale and continuity of mineralization, bringing it closer to identifying what could be a significant copper deposit.
