Valeriano is ATEX's 100%-owned flagship copper-gold exploration project in Huasco Province. The September 2025 resource includes a near-surface oxide-gold domain and a much larger underground-constrained sulphide porphyry, but no PEA or economic study has been published. Phase VI completed 28,400 metres and a five-year exploration environmental declaration was submitted in April 2026.
