The 2023 Tetra Tech PFS (effective February 20, 2023) outlines a low-strip (2.33) open pit feeding a 136,000 tpd plant with HPGR grinding, desalinated water and dry stacked filtered tailings over an initial 26-year life. Drilling under the 350-hole Revised Environmental License is suspended by a March 2022 Environmental Court injunction (vizcacha/Andean cat habitat); invalidation claims were rejected in January 2024 and remain under appeal. Burdened by aggregate NSRs of 2.25% (surface) / 1.125% (underground). 2024 UAV magnetics support NE/W extensions and the Brecha Sericita, El Rozal and Breccia Roca targets.
