Project overview and strategy

• 100% ownership of a large, high-grade copper-gold porphyry system in Chile, with rapid growth since 2021 and ongoing expansion through systematic drilling and district consolidation.

• Over 45,000m drilled in four phases, with Phase VI exceeding 25,000m and expanding the mineralized footprint; system limits remain undefined.

• District-scale exploration strategy targets both the main Valeriano system and regional prospects like Nuevo Horizonte, leveraging geological and geophysical signatures.

• Multiple porphyry-style targets identified across a 25,000 ha land package, with ongoing consolidation of surface rights and regional exploration.

• Supported by a strong management team and major shareholders, including Agnico Eagle (~16%) and Pierre Lassonde (~10%).

Resource growth and drilling results

• 2025 Mineral Resource Estimate (MRE): 475 Mt @ 0.88% CuEq Indicated and 1.51 Bt @ 0.75% CuEq Inferred, totaling 34 Blbs CuEq, with high-grade B2B zone (+50 Mt @ +1.5% CuEq).

• Phase VI drilling delivered record holes, expanding both the B2B breccia and high-grade porphyry trends, with mineralization open in multiple directions.

• Notable intercepts include 584m @ 1.27% CuEq, 164m @ 2.77% CuEq, and 86m @ 3.84% CuEq in ATXD25C; 887m @ 1.06% CuEq and 186m @ 2.15% CuEq in ATXD26B.

• Metallurgical tests confirm robust copper and gold recoveries (92–95% Cu, 90–97% Au) and marketable concentrate grades.

• Ongoing technical studies and independent reviews support resource growth and de-risking.

Infrastructure and operations

• Located in a globally significant copper district with access to regional infrastructure, including power, water (desalination), and ports.

• No structural power constraints identified; Chile’s unified grid and new renewable projects enhance supply reliability.

• Water supply options include shared regional desalination infrastructure, with long-term monitoring and planning.

• Geotechnical and mining studies completed to support future development pathways and reduce technical uncertainty.
