Andina Copper drills 272 m of 0.50% Cu at Cobrasco

• Andina Copper Corp. reported drill intercepts from hole CDH008 at the Cobrasco project in Chocó, Colombia on May 13, 2026.
• Key intercept: 272 m @ 0.50% Cu, 75 ppm Mo, and 1.92 g/t Ag from 52 m depth.
• Includes a higher-grade interval of 152 m @ 0.67% Cu, 68 ppm Mo, and 1.90 g/t Ag from 54 m depth.
• The mineralized footprint has expanded to approximately 1,100 m along strike and 550 m laterally.
• Mineralization is open in all directions with a northwest extension confirmed.
• Geological observations include chalcocite coating hypogene sulphides suggesting secondary copper enrichment.
• Operational update: A second diamond drilling rig is being mobilized to support definition drilling for Cobrasco Central and new porphyry centers.
• Hole CDH009 is completed with assays pending; CDH010 is currently in progress.

• Incremental Validation: The results confirm the northwest extension of the Cobrasco Central porphyry system, consistent with previous drill holes (CDH003 through CDH007) released between February and April 2026.
• Grade Comparison: While significant, the average grade in CDH008 (0.50% Cu over 272m) is lower than the peak grades reported in earlier holes like CDH003 (1.17% Cu over 118m). This suggests a large-scale porphyry system rather than high-grade pockets, which aligns with market expectations for this project type but does not represent a surprise grade upgrade.
• Price Context: The stock price has already rallied significantly from the March financing level of $0.80 to recent highs near $1.05 on previous positive drill results and financing news. This latest result is largely priced in given the consistent positive flow over the last three months.
• Capital Needs: The mobilization of a second rig indicates continued capital expenditure requirements, reinforcing the need for future financings which poses dilution risk to existing shareholders.
• Classification: The news is positive and confirms project viability but lacks the unexpected magnitude required for a "Material - Positive" rating given the established trend. It is best categorized as Routine - Positive.

• Company: Andina Copper Corp. (TSX-V: ANDC).
• Flagship Project: Cobrasco Cu-Mo Porphyry Project in Chocó, Colombia.
