Luca Mining Corp. Reports New Assay Results From 2026 Drilling Program At Tahuehueto Gold-Silver Mine

Luca Mining Corp. reported new assay results from its ongoing 2026 drilling program at the Tahuehueto gold-silver mine in Durango, Mexico. Exploration drilling has continued to intersect high-grade gold mineralization in newly identified breccia zones, close to current mine workings, confirming continuity of breccia-hosted mineralization within the Creston vein system and highlighting the potential for near-mine resource expansion. Drilling confirmed the continuity of mineralization in previously untested areas located 20 to 35 m below Level 20, extending known high-grade breccia zones at depth and further validating Luca's geological model. Intercepts exceed current mined grades and occur within development distance of existing underground infrastructure, supporting potential integration into the near-term mine plan. Verified vein-related mineralization at the Creston Vein in close proximity to current mining faces through the Termite drill program. Two contracted diamond drill rigs are currently on site and in operation, one dedicated to underground drilling and one to surface drilling. A Luca owned and operated underground rig continues to define mineralization identified in the near-term mine plan. To date, Luca has completed 54 underground holes for 10,426 m and 25 surface holes for 4,599 m. Drillholes DDH26-SU-14 through DDH26-SU-16 targeted a previously untested zone approximately 30-40 metres below active mine workings on Level 23 and along strike from Luca's successful Phase 1 2024-2025 underground drill program. Drillhole DDH26-240 targeted and intercepted the El Rey vein approximately 40m below the previous deepest intercept from DDH26-239. All drillholes (with the exception of DDH26-SU-15 and DDH26-SU-16) intersected the Creston and Perdido vein structures in well-developed brecciated veins and confirm strike continuity of the high-grade breccia zones identified in prior drilling, on strike and down plunge. The fact DDH26-SU-15 and DDH26-SU-16 did not intersect the mineralized structure is interpreted to be related to previously identified dilatational jogs in the veins, these areas are related to nearby high-grade brecciated targets elsewhere on the Property, and a follow-up drill program to further delineate this priority target is now being designed and slated to be implemented before the end of the year. To date, Luca has completed 54 underground holes for 10,426 m and 25 surface holes for 4,599 m using "HQ", "NQ" and/or "BQ" sized diamond drill core (Creston, Perdido, El Rey and Santiago targets). The current campaigns represent the first substantive exploration drilling conducted on the property in more than 12 years, and the first since the addition of key concessions to the land package. Luca's 2026 exploration program builds on the success of the 2025 campaign. The program is designed to expand known mineral resources, adding near-term mineable material and defining the vertical and lateral extent of mineralization, as well as to identify additional thick, high-grade breccia zones known to occur within the epithermal vein system, and test multiple underexplored vein systems. In addition to the four veins that currently support the mineral resource, at least 14 additional prospective veins have been documented within the concession area with potential to host epithermal Au-Ag (±Cu-Zn-Pb) mineralization. In several cases, these targets may represent extensions of the existing mineralized structures. Overall, the Company has identified more than 11 km of prospective vein structures along strike, compared to approximately 4.5 km of mineralized veins incorporated into the current mineral resource model, highlighting significant exploration upside across the property.
