Luca drills 14g gold that may grow Mexico mine

Promising Gold Intercepts at Tahuehueto

Luca Mining (TSXV: LUCA) has announced significant gold discoveries beneath the existing infrastructure at its Tahuehueto mine in Mexico. These findings suggest the potential for substantial resource expansion and increased production capacity. Recent drilling results have revealed high-grade gold mineralization, fueling optimism for the mine's future.

Specifically, drill hole DDH26-SU-01 intersected 7.6 meters grading 14.27 grams of gold per tonne, along with 46.64 grams of silver, 0.33% copper, 2.57% lead, and 1.19% zinc, starting from a depth of 80.9 meters. Further encouraging results came from drill hole DDH26-SU-03, which yielded 13.2 meters grading 6.66 grams of gold, 17.18 grams of silver, 0.04% copper, 0.25% lead, and 0.65% zinc, beginning at 42.7 meters downhole.

Analyst Commentary and Strategic Implications

According to Canaccord Genuity mining analyst Phil Kerr, Luca Mining's drilling success continues to yield high-grade mineralization along the Creston vein system, at levels exceeding current head grades, which are approximately 4 grams gold-equivalent. Kerr also noted the strategic advantage of these new drill holes being located just 30 meters below Level 23, where established underground infrastructure already exists.

"We see the ongoing exploration success validating Luca’s geologic model," Kerr stated, emphasizing the potential for mine life extension through resource growth. The proximity to existing infrastructure offers an opportunity to integrate new zones into the near-term mine plan.

These discoveries arrive at a crucial time, as gold prices have experienced a substantial increase of around 65% in the past year. This surge has heightened investor interest in producers capable of expanding high-grade resources near existing infrastructure. Amidst evolving mining policies in Mexico, which include a halt to new mining concessions and stricter federal oversight, expanding resources around existing operations becomes increasingly vital for companies like Luca Mining.

Increased Exploration Budget and Future Outlook

Despite a slight dip of 0.3% to C$1.72 per share on Friday, Luca Mining holds a substantial valuation of C$471 million ($346 million). The Tahuehueto mine, located in Durango, has a production capacity of 1,000 tonnes per day and achieved commercial production in 2025.

The company's board has approved a 40% increase, amounting to $1 million, in the 2026 exploration budget at Tahuehueto, bringing the total to $3.5 million. This expanded budget will support the exploration of 14 prospective vein targets. To date, Luca Mining has completed 28 underground drill holes (approximately 6,750 meters) and 19 surface holes (around 3,650 meters) across the Creston vein and nearby Santiago targets as part of this year's program.

Paul D. Gray, Luca’s vice-president of exploration, highlighted that the results validate the Tahuehueto geological model and underscore the opportunity to expand high-grade mineral resources within development distance of existing infrastructure.

"With both underground and surface rigs active, and an expanded drill budget, we are well positioned to continue defining high-grade mineralization and demonstrating the broader scale of the Tahuehueto system," Gray stated.
