Recent High-Grade Gold Intercepts at Tahuehueto Mine

Luca Mining Corp, listed on TSX-V under the symbol LUCA, has shared exciting updates from its ongoing exploration at the Tahuehueto gold-silver mine located in Durango, Mexico. On May 5, 2026, the company released assay results that reveal valuable insights into the mine's mineral potential.

Exploration Highlights

The current drilling efforts at the Tahuehueto site have uncovered high-grade gold mineralization, especially in newly identified breccia zones that sit close to existing mine workings. This discovery indicates a promising continuity of breccia-hosted mineralization within the Creston vein system.

Significantly, it is expected that parts of these newly earmarked mineralized breccia zones might easily be included in the mine's resource models and put into production within the next year. Outstanding drill results have emerged not only from surface drilling but also from underground efforts aimed at revamping the historic El Rey vein, which has remained untouched since 1983.

Paul D. Gray, the company's VP of Exploration, commented on the surface drilling results, emphasizing how they confirm that high-grade breccia zones remain unexploited below current workings. Furthermore, the El Rey vein has proved mineral-rich, prompting increased priority for this area as exploration continues.

Detailed Assay Results

Among the highlighted results, several drill holes returned decisive lengths and grades:

• - Drill hole DDH26-SU-07 encountered 6.8 meters of 5.54 grams per tonne (g/t) gold equivalent, comprising 4.08 g/t gold and 58.79 g/t silver. Notably, this included a remarkable 1.0 meter section yielding 22.35 g/t gold equivalent.
• - Another hole, DDH26-SU-04, revealed 4.5 meters of 4.50 g/t gold equivalent, which also contained 2.6 meters of substantially higher grades averaging 5.59 g/t.
• - Moreover, 2.5 meters of 3.57 g/t gold equivalent were found in DDH26-SU-10, with high grades embedded in the structure.

These findings show not only the continuity but the extension of known high-grade breccia zones and encourage development operations given their proximity to existing underground infrastructure. The data collected thus far suggests that these intercepts exceed the current mined grades, opening avenues for future resource expansion.

Advancing Exploration Operations

Currently, Luca Mining employs two external diamond drill rigs: one for surface applications and another for underground operations. Additionally, they have introduced a Luca-owned drill rig to support their expanding exploration efforts, reflecting an increased budget of approximately $2.4 million aimed at future advancements at Tahuehueto.

As the drilling campaign progresses, a comprehensive exploration program has been established. This aims not only to broaden existing mineral resources but also to identify additional high-grade zones that may contribute to mine development timelines. There is anticipated potential to quantify further mineralized structures, with over 14 additional prospective veins documented within the vast concession area.

Conclusion

The positive results from the Tahuehueto Mine underscore Luca Mining Corp's commitment to identifying and developing resource opportunities. As the exploration phase continues, company officials remain optimistic about the prospects, hoping to integrate new data into their operational framework. The findings will not only bolster the company’s current standing but also enhance its prospects for future developments in the mining sector.
