Slide 3: Andina Copper: Actively Exploring Across South America
ANDINA COPPER: ACTIVELY EXPLORING ACROSS SOUTH AMERICA • TWO NEW PORPHYRY COPPER DISCOVERIES (Cobrasco, Colombia and Piuquenes, Argentina) • COBRASCO: AN EMERGING, UNDEREXPLORED PORPHYRY BELT IN WESTERN COLOMBIA 12 of 13 holes reported returned significant Cu-Mo intercepts. Drill defined footprint ~
Slide 4: Cobrasco: Regional Geological Setting
COBRASCO: REGIONAL GEOLOGICAL SETTING Acandí • Cobrasco lies within the emerging 48.1±0.1Ma (K-Ar) Chocó porphyry copper belt of western Colombia. • Historical exploration has been localized, with limited systematic exploration across the belt. Murindó - La Rica Murindó 54.7±1.3Ma (K-Ar) • Key depos

Slide 6: Cobrasco: Local Geology
COBRASCO: Local Geology • Microdiorite, daci-andesitic porphyries Mandé Batholith intrusions and andesites (Santa Cecilia-La Equis) host the magmatic-hydrothermal system. • Quartz-eye rhyolite porphyries (41 to 43 Ma) intrude the host lithologies along an overall NW – oriented structural corridor. •
Slide 7: Cobrasco: Drilling and main intercepts
COBRASCO: Drilling and main intercepts • 15 drillholes completed to date, totaling more than 13,000 m. • Large 1,300 × 500 m footprint. • Mineralization open in several directions. Hole Intercept (downhole length) 808m @ 0.42% Cu, 79ppm Mo from 184m CDH001 incl. 82m @ 0.90% Cu, 199ppm Mo from 774m 7
Slide 8: Composite section A-A′ (looking east)
COBRASCO: Composite section A -A′ (looking east) • Composite section through the drilling completed to date. • Long Cu–Mo intercepts define a large, vertically continuous mineralized volume. • Mineralization remains open laterally in several directions • The scale and continuity support the potentia

Slide 10: Cobrasco: Hydrothermal Alteration-Mineralization
COBRASCO: Hydrothermal Alteration -Mineralization At Cobrasco, the principal Cu-mineralization occurred during hydrolytic (sericite-dominant) alteration, rather than during the earlier potassic stage.

Slide 14: Key Conclusions
COBRASCO: KEY CONCLUSIONS • Discovery and scale. Cobrasco is a sizable porphyry Cu–Mo discovery. Its large mineralized footprint, long mineralized intercepts and near-surface mineralization support the potential for a major, and possibly giant, copper deposit. • Expansion potential. The known minera
