Key Operational Enhancements at Luca Mining Corp.

Luca Mining Corp. has recently shared a positive update regarding its initiatives aimed at enhancing operational efficiencies at its Campo Morado and Tahuehueto mines. With new leadership in operational roles, the company is advancing projects designed to improve both mill performance and mining activities at these locations.

Campo Morado Mine Progress

At Campo Morado, the performance of mining contractor Cominvi has been noteworthy. Thanks to improved mine planning, Luca has been able to create a substantial surface stockpile of approximately 63,000 tonnes of mineralized material as of May 31, 2026. This figure represents a remarkable increase from fewer than 12,000 tonnes recorded at the end of December 2025. In terms of mill throughput, the operation has maintained strong performance levels with an average of around 1,900 tonnes per day (tpd) during April and May. The establishment of this significant ore stockpile will enable Luca to optimize the mill feed blend effectively, which is anticipated to enhance overall metallurgical recovery performance. This will also facilitate the design and execution of additional optimization programs planned for the coming months.

Tahuehueto Mining Improvements

At the Tahuehueto mine, a combination of increased mining rates—driven by contractor La Cantera's performance—along with improved mill availability has resulted in more consistent mining and milling rates. As of April and May, the milling rates at this operation have surpassed 1,050 tpd, marking an increase of over 5% compared to the first quarter of 2026. This consistency bodes well for the overall productivity and operational success of the mine.

Insights from the Leadership

Dan Barnholden, the CEO and Director of Luca, commented on these developments, noting, "Under new operational guidance led by COO Nick Shakesby, who joined us in April, we've quickly enacted various initiatives across both projects to lower risks and streamline our mining and milling processes. We are optimistic about maintaining this momentum as we unlock further potential of our assets."

Corporate Changes Announced

In addition to operational advancements, Luca Mining Corp. has also noted changes within its corporate structure. The company announces the departure of Ramón Mendoza, the Chief Technical Officer, and Dr. Jose Hernandez, Vice President of Metallurgy and Process Engineering. Luca would like to express gratitude for their contributions and wishes them well in their future endeavors.
