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 expanded the known limits of the zone while providing important geological information that will support evaluation of the zone for inclusion in the long-term Campo Morado mine plan.__Drilling efforts continue on both surface and underground targets with a focus on testing under-explored areas close to existing underground infrastructure."_ **Near-Mine Underground Drilling** Underground drillhole CMUG-26-42 through CMUG-26-45 targeted the Largo Norte zone and successfully intersected mineralization in each of these drillholes from this unmined zone, including: Naranjo: - CMUG-26-42: - **47.2 m of 1.79 g/t Au, 44.63 g/t Ag, 0.68% Cu, 0.46% Pb and 2.49% Zn **from 25.8 m, including**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 which includes **0.7 m of 3.35 g/t Au, 113.80 g/t Ag, 4.20% Cu, 0.24% Pb and 1.79% Zn**from 43.0 m - CMUG-26-43: - **93.7 m of 0.86 g/t Au, 48.21 g/t Ag, 1.14% Cu, 0.14% Pb and 1.06% Zn **from 0.0 m, including**15.0m****of 0.93 g/t Au, 81.20 g/t Ag, ****3.08% Cu,****0.09% Pb and 1.31% Zn **from 29.5 m - CMUG-26-44: - **64.0 m of 1.43 g/t Au, 54.47 g/t Ag, 0.52% Cu, 0.30% Pb and 1.30% Zn **from 0.0m, including **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 - CMUG-26-45: - **107.6 m of 0.95 g/t Au, 33.74 g/t Ag, 0.64% Cu, 0.22% Pb and 1.33% Zn**from 0.0 m; including **29.6 m of 1.37 g/t Au, 48.27 g/t Ag, 0.55% Cu, 0.52% Pb and 2.39% Zn**from 75.7 m El Rey: - CMRY-26-10: - **28.4 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, including s high-grade interval of **9.7 m of 4.09 g/t Au, 208.99 g/t Ag, 0.74% Cu, 1.33% Pb and 5.05% Zn**from 111.3 m - CMRY-26-11: - **5.8 m of 2.15 g/t Au, 74.72 g/t Ag, 0.49% Cu, 0.64% Pb and 0.65% Zn **from 103.4 m, and**7.6 m of 1.11 g/t Au, 80.35 g/t Ag, 0.68% Cu, 0.44% Pb and 5.62% Zn **from 111.0 m - CMRY-26-12: - **2.2 m of 3.45 g/t Au, 8.58 g/t Ag, 0.06% Cu, 0.07% Pb and 0.28% Zn **from 123.0 m These recent intersections from the unmined Naranjo zone highlight the multiple opportunities to add additional mineable resources proximal to current development headings, existing infrastructure and expand previously defined mineral resources. Moreover, the El Rey drillholes analytical results continue to showcase the potential to add tonnage to new areas currently being developed into the long-term Campo Morado mine plan. Surface drilling continues, with the current focus on Estrella de Oro and Naranjo in conjunction with on-going underground drilling planned to target the A9, Muneco, Bajo and Fish deposits, which all contribute to the 2026–2028 mine plans.
