Luca Intersects 6.8 Metres of 5.5 g/t Gold Equivalent at Tahuehueto Mine - Further Expanding High-Grade Mineralization Proximal to Existing Workings
Luca Mining Drilling Confirms Tahuehueto Grade Continuity Amidst Balance Sheet Cleanup

Executive Summary
- Luca Mining Corp. reported high-grade gold-silver assay results from its 2026 drilling program at the Tahuehueto mine in Durango, Mexico.
- Key intercept includes DDH26-SU-07: 6.8m @ 5.54 g/t AuEq including 1.0m @ 22.35 g/t AuEq.
- Mineralization confirmed in newly identified breccia zones near existing workings, with potential for integration into production within one year.
- Exploration of the El Rey vein (unexplored for over 20 years) successfully intersected mineralized breccia zones.
- Company is increasing its 2026 exploration budget by an additional $2.4 million for the remainder of the year.
- Two contracted diamond drill rigs are active plus a Luca-owned underground rig.
Material Impact
- The news confirms ongoing success in the company's $25 million three-year exploration program announced in November 2025, validating the strategy rather than introducing new variables.
- High-grade intercepts near existing workings support the narrative of mine life extension and potential cost reduction at Tahuehueto, where AISC has risen significantly (67% YoY to $2,832/AuEq oz in 2025).
- The budget increase ($2.4M) is manageable given the strong cash position ($36.4M as of Q1 2026) and does not signal distress or unexpected capital needs.
- Given the stock's recent decline from $2.05 (Jan 2026) to $1.21 (May 2026), this news acts as a stabilizer but is unlikely to trigger a sharp reversal without further catalysts like the Campo Morado Expansion Study results expected in H2 2026.
- The market has already priced in exploration success through previous drilling releases (Jan, Feb, Mar, Apr); therefore, this release is viewed as incremental confirmation of existing thesis rather than a fundamental re-rating event.
