Luca intersects 28.4 m of 2.3 g/t Au, 135 g/t Ag, 0.6% Cu, 1% Pb, 3.7% Zn at El Rey

Canada NewsWire VANCOUVER, BC , June 23, 2026 /CNW/ - Luca Mining Corp.  ("Luca" or the "Company") (TSXV: LUCA) (OTCQX: LUCMF) (Frankfurt: Z68) is pleased to announce new underground drill results from its ongoing exploration program at the Campo Morado polymetallic VMS mine in Guerrero State, Mexico. Highlights Continued success in the definition of high-grade, gold and silver-rich VMS mineralization in areas both adjacent and proximal to active underground workings at Campo Morado  Surface drillhole CMRY-26-10 intersected 28.4 metres ("m") of 2.28 g/t Au, 134.89 g/t Ag, 0.57% Cu, 0.95% Pb and 3.69% Zn from 104.2m, expanding the known mineralized footprint in the unmined El Rey zone Underground drillhole CMUG-26-44 intersected 19.6 m of 2.78 g/t Au, 103.12 g/t Ag, 0.52% Cu, 0.67% Pb and 2.75% Zn from 40.5 m in the unmined Naranjo zone Underground drillhole CMUG-26-42 intersected 20.6 m of 3.05 g/t Au, 50.69 g/t Ag, 0.65% Cu, 0.43% Pb and 1.57% Zn from 41.5 m, expanding previously defined mineralization in the unmined Naranjo zone Exploration drilling operations continue at Campo Morado with two surface drill rigs and one underground drill rig – 12,035 m drilled from underground in 52 drillholes and 16,535 m drilled from 68 surface drillholes to date Paul D. Gray, Luca's VP of Exploration, commented: "This latest batch of drill results from the ongoing Campo Morado exploration campaign highlight the untapped potential of two of several unmined areas on the Campo Morado Property, El Rey and Naranjo. The Naranjo zone is known to be over 540 metres in length, up to 210 metres wide and averages approximately 60 metres in width.

These new underground drillholes have expanded the zone while increasing confidence in the continuity of mineralization with more closely spaced drilling. At El Rey, surface drilling has also expan
