VALERIANO COPPER-GOLD PROJECT
A New Giant High-Grade Discovery in Chile
July 2025 TSXV: ATX
A Large Scale, High-Grade Copper-Gold Project
Significant and growing Mineral Resource with 2023 Inferred Resource of 1.41 billion tonnes of Cu-Au grading 0.67% CuEq1
Phase V (~16,600m) drill program delivering the highest-grades to date, supporting a meaningful Mineral Resource update in H2 2025
High grade breccias "B2B Zone" holes ATXD23A and ATXD26 grading over 2% CuEq1
support a high-grade underground starter mine closer to surface
Strong recoveries of up to 95% Cu / 97% Au at a coarser grind, producing a clean marketable concentrate
Mineralization open in all directions and at depth; drilled over 1.4 km strike and is 1 km wide; limits of system are unknown
100% in Chile, district still largely untested with strong potential for additional nearby
porphyry discoveries
Agnico Eagle Mines is a strategic partner investing C$55 million
