Phase Two Program At The Campo Morado Mine

VANCOUVER — Luca Mining Corp. report on the ongoing Phase 2 exploration program at the Campo Morado polymetallic VMS mine in Guerrero State, Mexico, including the first drilling at the El Rey deposit in over 14 years. Initial results indicate thick, gold- and silver-rich VMS mineralization at El Rey, an unmined deposit located approximately 200 metres from the Reforma deposit and close to existing underground infrastructure, supporting its potential inclusion in the longer-term Campo Morado mine plan.
First drilling at the El Rey VMS deposit in over 14 years confirms thick, high-grade gold- and silver-rich mineralization. 28.6 m of 5.35 g/t AuEq, including 2.8 m of 12.55 g/t AuEq (CMRY-25-02). 21.0 m of 6.13 g/t AuEq, including 2.2 m of 25.38 g/t AuEq (CMRY-25-06). El Rey is an unmined VMS deposit ~200 m from the Reforma deposit, close to existing underground infrastructure. Mineralization extends beyond historical models, particularly to depth and along the western margin. Results support mine life extension and improved production flexibility at Campo Morado.
Two surface drill rigs are currently operating at Campo Morado in parallel with ongoing underground diamond drilling. Together, these programs are targeting previously undrilled, high-priority VMS targets across the Camp, as well as continued drilling at the Reforma and El Rey deposits.
To date, approximately 8,200 m of surface drilling and 8,700 m of underground drilling have been completed. Underground drilling continues to target the Largo, Largo Norte, Naranjo and Fish deposits, all of which form part of the 2026–2028 mine plans.
