The intercept in hole DDH26-RCE-01 includes a 1.0-metre section grading 27.56 g/t gold equivalent from 205.4 metres downhole. The Catorce Zone is situated approximately 250 metres from existing underground development and is interpreted as a southern extension of the Creston vein system. Luca Mining has additional assay results pending from ongoing drilling at the target.

The company also completed 14 underground drillholes targeting the Creston Vein from Level 20, intersecting high-grade mineralization in all holes at depths of 20 to 35 metres below active workings. Additional production verification drilling at the Perdido Vein using an on-site Termite rig returned 0.9 metres of 7.60 g/t gold equivalent in hole TRT26-07. Mining of scheduled areas targeting the Perdido vein at the Tahuehueto Mine is planned during H2 2026 and H1 2027.

“The latest results continue to reinforce our view that Tahuehueto has significant expansion potential beyond the current resource areas,” stated Paul D. Gray, VP Exploration. “ At Creston, all 14 drillholes targeting the breccia zone below Level 20 have intersected the vein, demonstrating excellent continuity and providing further confidence in the potential to expand the structure at depth.

“Equally exciting is the first surface drilling from the Catorce Zone since 2008, where the first hole returned 9.9 metres of 5.39 g/t AuEq, including 1.0 metre of 27.56 g/t AuEq. This strong result from a previously underexplored area supports our view of the unrealized exploration potential across the property, which we continue to uncover with additional Catorce assays pending and ongoing drilling across multiple target areas.”

The Tahuehueto property comprises an epithermal gold-silver vein system covering approximately 10,000 hectares with 11 kilometres of known vein strike length. Tahuehueto is one of two 100%-owned producing mines operated by Luca Mining within the Sierra Madre mineralized belt in Mexico.
