Luca Mining Announces Final Commissioning Phase at the Tahuehueto Gold Mine, and the Appointment of New Director

VANCOUVER, Feb. 8, 2024 - Luca Mining Corp. ("Luca" or the "Company") (TSXV: LUCA) (OTCQX: LUCMF) (Frankfurt: Z68) is pleased to provide an update on progress at its wholly-owned Tahuehueto Gold Mine in Durango, Mexico, and announces the addition of Mr. Peter Damouni to the Company's Board of Directors.

• The project to increase throughput at the Tahuehueto mill to 1,000 tonnes per day is in the final commissioning stage. Testing of the second ball mill, which was the last component in the project, is well advanced and will provide a total installed grinding capacity of 1,250 tonnes per day ("tpd").
• The Luca Board welcomes Peter Damouni as a new Director. Peter brings considerable market, finance and corporate experience and will open new opportunities for Luca.

Testing of the final equipment to complete construction of the 1,000 tpd operation is almost complete. In the crushing circuit, a new vibrating screen is also currently being installed, to further improve crusher system availability.

Final alignment and testing of the second 750 tpd ball mill will complete mid-February, providing an installed grinding capacity of 1,250 tpd. With routine planned maintenance downtime each month, this will ensure an actual production rate of 1,000 tpd. The other key element of this project was the second tailings press filter, which is already in operation and working in parallel with the first press filter. As a result, daily production is increasing. With the second mill commissioned, production will then progressively ramp-up to 35,000-40,000 oz gold equivalent per year.

Mike Struthers, CEO, commented, "Our team at Tahuehueto continues to push hard to commission the 1,000 tpd project at the mine. Once the second mill is commissioned, the installed grinding capacity of 1,250 tpd will provide valuable flexibility. These are very exciting times for Luca and its shareholders. The next few months will feature the achievement of a number of significant milestones that shareholders have been looking forward to since we completed our major financing and reorganization mid 2023. In particular, Luca will bring a brand-new gold mine into commercial production and with the mine optimization plan being implemented at Campo Morado we have already experienced significant cash flow improvements, which we intend to publicize on a regular basis."

New Director

The Luca Board is very pleased to welcome Mr. Peter Damouni to the Luca team. Mr Damouni has over 20 years of corporate and investment banking experience with a focus on the natural resource sector. He has served as an executive and director of a number of public companies listed on the TSX, TSXV, and LSE. During his career, he has been instrumental in developing and executing corporate strategies including equity and debt financings, restructurings, joint ventures, acquisitions and sale processes.

Mike Struthers, CEO, stated; "Having worked closely with Peter in the past, I'm very pleased to have Peter join the Luca team. He brings considerable markets, finance and corporate experience which will open new opportunities for Luca as we continue to realise our goals for 2024 and beyond."

It should be noted that Luca declared commercial production at Campo Morado prior to completing a feasibility study of mineral reserves demonstrating economic and technical viability. Accordingly, readers should be cautioned that Luca's production decision has been made without a comprehensive feasibility study of established reserves such that there is greater risk and uncertainty as to future economic results from the Campo Morado mine and a higher technical risk of failure than would be the case if a feasibility study were completed and relied upon to make a production decision. Luca has completed a preliminary economic assessment ("PEA") mining study on the Campo Morado mine that provides a conceptual life of mine plan and a preliminary economic analysis based on the previously identified mineral resources (see news releases dated November 8, 2017, and April 4, 2018).
