Significant and growing Mineral Resource, total of 2 billion tonnes of Cu-Au grading 0.78% CuEq*
Phase V drill program has already delivered the highest-grade intersections to date, with momentum to continue in Phase VI
B2B zone holes ATXD23A (152m grading >2% CuEq)** and ATXD26 (68m grading >2% CuEq)*** present optionality and a conceptual high-grade underground starter mine closer to surface
Metallurgical work supports up to 95% Cu / 97% Au recoveries at a coarser grind, and a clean marketable concentrate with negligible deleterious elements
Scalability with mineralization +1.4 km along strike, +1 km wide, and open in all directions
100% in Chile, district still largely untested with additional porphyries likely in hiding
Agnico Eagle Mines is the largest cornerstone investor investing C$55 million
