Luca Intersects 7.6 Metres of 16.1 g/t Gold at Tahuehueto Mine - Expanding High-Grade Mineralization Near Existing Workings

Core Insights - Luca Mining Corp. has reported high-grade gold mineralization results from its ongoing drilling program at the Tahuehueto gold-silver mine in Durango, Mexico, confirming the continuity of breccia-hosted mineralization and highlighting potential for resource expansion [1][2] - The company has increased its 2026 drill budget by 40% to $3.5 million based on strong drilling results, with a total of 28 underground holes and 19 surface holes completed to date [1][2] - Significant high-grade intercepts were recorded, including 7.6 meters of 16.08 g/t AuEq and 5.4 meters of 16.00 g/t AuEq, indicating strong continuity of mineralization in unmined areas [1][2] Drilling Results - The drilling program targeted a previously untested zone approximately 30 meters below active mine workings, confirming the strike continuity of the high-grade breccia zone [1][2] - Key intercepts include: - DDH26-SU-01: 7.6 m @ 16.08 g/t AuEq (14.27 g/t Au, 46.64 g/t Ag, 0.33% Cu, 2.57% Pb, 1.19% Zn) [1][2] - DDH26-SU-02: 1.9 m @ 6.77 g/t AuEq (1.38 g/t Au, 178.00 g/t Ag, 2.38% Cu, 0.76% Pb, 0.69% Zn) [1][2] - DDH26-SU-03: 13.2 m @ 7.11 g/t AuEq (6.66 g/t Au, 17.18 g/t Ag, 0.04% Cu, 0.25% Pb, 0.65% Zn) [1][2] Exploration Program - The 2026 exploration program aims to expand known mineral resources and define the vertical and lateral extent of mineralization, with at least 14 additional prospective veins documented within the concession area [1][2] - The Tahuehueto property features approximately 11 kilometers of known vein strike length, with significant exploration upside compared to the current mineral resource model [1][2]
