LUCA STRENGTHENS TECHNICAL LEADERSHIP WITH APPOINTMENT OF COO AND BUILDS TEAM TO EXECUTE ON MINE OPTIMIZATIONS

VANCOUVER, BC, March 9, 2026 /CNW/ - Luca Mining Corp. ("Luca" or the "Company") (TSX-V: LUCA) (OTCQX: LUCMF) (Frankfurt: Z68) is pleased to announce the appointment of Nick Shakesby as Chief Operating Officer ("COO"), effective April 1, 2026. Luca has also strengthened its technical team to advance and execute on optimization and growth initiatives, including the Campo Morado Expansion ("CME").

The CME is a mill optimization and expansion study and mine plan update for the Campo Morado mine, targeting improved recovery rates of all metals, most notably an expected significant increase in gold and silver recoveries at the operation (see Company press release dated February 18, 2026). The CME, life of mine plan, and Mineral Reserve estimate will be delivered in a Technical Report to be prepared in accordance with NI 43-101, expected to be released in the second half of 2026.

Luca's new technical team has been assembled to provide deep management experience and expertise in overseeing and executing on the asset optimization and transformational growth opportunities ahead for the Company. 

Nick Shakesby, Luca's new COO, is a senior mining executive with more than 30 years of operational and project leadership experience across underground mining operations globally, with a strong focus on Mexico and Latin America.

Mr. Shakesby joins Luca from COMINVI S.A., Mexico's largest underground mining contractor, where he has served as Chief Executive Officer since 2023. Previously, Mr. Shakesby served as Vice President, Operations and Country Manager, Mexico at Endeavour Silver Corp., where he was responsible for four operating underground mines. He resides in Mexico and is fluent in Spanish and English.

Ramón Mendoza, currently Chief Operating Officer and Chief Technical Officer ("CTO"), will transition to a dedicated CTO role focused on leading Luca's growth initiatives, including the recently announced CME. The CME is expected to consist of a two-phase expansion at the Campo Morado processing facility and will include an updated mine plan for the operation. Mr. Mendoza will oversee this exciting brownfields growth opportunity, ensuring the project's execution and delivery.

In addition, Luca has hired Dr. Jose Hernandez as Vice President, Metallurgy and Process Engineering, effective March 1, 2026. Dr. Hernandez is a globally recognized metallurgical leader and will work closely with the COO and CTO to deliver Luca's operational optimization and growth initiatives. Most recently, Dr. Hernandez served as Manager, Project Metallurgy at Teck Resources and is fluent in Spanish and English.

These appointments expand and strengthen Luca's operational and technical leadership as the Company advances optimization initiatives at both of its operating mines and executes its near-term growth strategy.

Dan Barnholden, Luca's CEO and Director, commented, "We are very pleased to welcome Nick to Luca at an important stage in the Company's growth. Nick will oversee all mining operations, with responsibility for operational performance, safety, cost management, and integration of the Campo Morado Expansion, strengthening our ability to deliver safe, stable, and efficient production at both Campo Morado and Tahuehueto.

"We are equally pleased that Ramón Mendoza will continue as CTO, where his full focus will be on overseeing and advancing our growth pipeline and delivering the CME. Dr. Jose Hernandez will play a key role in all these initiatives, as we optimize and improve the metallurgical process at both our mines and execute on what we believe will be an industry-leading brownfields expansion at our Campo Morado mine."
