South America Portfolio Strategy To De-Risk Exploration

  • Andina runs a three-project South American porphyry portfolio to reduce jurisdictional risk and ensure year-round news flow.
  • Projects span Argentina (Piuquenes), Colombia (Cabrasco), and Chile (Mantau) so seasonality and permits let them rotate drilling across regions.
ANECDOTE

Piuquenes Rapid Follow Up On A Longheld Private Project

  • Piuquenes was privately held since the 1970s and Andina began drilling there in January 2024 to follow up historic shallow high-grade intercepts.
  • Early results included ~800 m from 50 m at ~0.4% Cu and 0.51 g/t Au with a strong oxidized near-surface zone, suggesting potential surface mining.

Piuquenes Drilling Focus On New Targets Not Just Central

  • Current Piuquenes activity uses two rigs testing multiple porphyry centers including Piuquenes East and a new large MT anomaly at Piuquenes North.
  • The plan for this season is to test three porphyry targets (East, North MT anomaly, and another center) rather than re-drilling Central.
