• Regulus completed an initial mineral resource estimate for an integrated Coimolache Sulfides/AntaKori copper-gold project in Peru under a 2024 collaboration.
• SRK Peru prepared the estimate as an internal report for the parties, removing property-boundary constraints to assess district-scale mineralization.
• The partners may proceed to a preliminary economic assessment, subject to mutual agreement; any disclosure requires joint consent and regulatory approvals.
• AntaKori hosts indicated resources of 250 million tonnes at 0.48% Cu, 0.29 g/t Au, 7.5 g/t Ag; inferred resources of 267 million tonnes at 0.41% Cu, 0.26 g/t Au, 7.8 g/t Ag.
• Total drilling at AntaKori reached 71,762 meters from 1997-2022; a further 31,666 meters were drilled since the 2019 resource estimate.
