LUCA INTERSECTS HIGH-GRADE GOLD AT REFORMA, INCLUDING 13 METRES OF 11.4 GRAMS PER TONNE GOLD EQUIVALENT

The most recent news, dated October 16, 2025, announces high-grade gold intercepts from surface drilling at the Reforma deposit, part of the Campo Morado mine property. Key highlights include: * CMRF-25-10: 13.0 metres of 11.4 g/t gold equivalent (AuEq), including a higher-grade core of 3.7 metres of 21.3 g/t AuEq. * CMRF-25-11: 24.6 metres of 6.0 g/t AuEq, including 11.6 metres of 8.6 g/t AuEq.

In response to these positive results and the overall success of the 2025 program, Luca is significantly expanding its exploration efforts. The surface drill program has been increased by 120% to 5,500 metres, and the underground program has been expanded by 50% to 7,500 metres for the year.

The drill results are excellent and materially positive for the company. They confirm the presence of significant high-grade, polymetallic mineralization at the Reforma deposit, a satellite target at Campo Morado that has not been the primary focus of mining. Intercepts like 13 metres of over 11 g/t AuEq are impactful and suggest the potential to add high-grade feed to the mill, which could improve profitability and extend the mine's life.

This news follows a consistent pattern of exploration success throughout 2025 at both the Campo Morado and Tahuehueto properties. The decision to significantly increase both the surface and underground drill programs demonstrates management's confidence in the geological potential and is a prudent use of capital given the strong results.

The timing of this positive news is also important. It was released one week after an announcement regarding an environmental inspection at the Tahuehueto mine, which caused a sharp, albeit temporary, drop in the stock price. This strong operational update helps to shift the narrative back to the company's successful execution of its exploration and growth strategy. While not a "game-changer," the news materially de-risks the exploration story and adds tangible value by outlining a clear path to resource expansion.

Luca Mining Corp. is a Canadian-based mining company with two operating mines in Mexico. 1. Campo Morado Mine (Guerrero State): A polymetallic underground volcanogenic massive sulphide (VMS) mine producing zinc, copper, and lead concentrates with significant gold and silver by-products. The company has focused on an optimization program to improve throughput, recoveries, and profitability. 2. Tahuehueto Gold-Silver Mine (Durango State): This is the company's flagship growth project. It is a new underground epithermal vein system mine that recently achieved commercial production on March 31, 2025. The focus here has been ramping up to a steady state of 1,000 tonnes per day and now expanding the resource through exploration.

The company's strategy has been to optimize operations at its two mines to generate strong cash flow, enabling it to aggressively pay down debt and fund high-impact exploration to extend mine life and make new discoveries.
