LUCA ACHIEVES TARGETED THROUGHPUT RATES AT CAMPO MORADO AND TAHUEHUTO MINES

In This Article:

VANCOUVER, BC, Feb. 5, 2025 /PRNewswire/ - Luca Mining Corp. ("Luca" or the "Company") (TSXV: LUCA) (OTCQX: LUCMF) (Frankfurt: Z68) is pleased to announce that programs underway to maximize operational efficiencies at both the Campo Morado zinc/copper/gold mine and the Tahuehueto gold/silver mine have yielded excellent results.

Campo Morado
The Company has achieved its targeted throughput rates at the Campo Morado zinc/copper/gold mine of 2,000 tonnes per day ("tpd"). This was a milestone set when Luca's newly contracted mining team, Cominvi, S.A. de C.V. ("Cominvi"), was seconded in August of last year. Cominvi, working with the Luca team, achieved sustained 2,000 tpd in the latter part of Q4 2024 and the Campo Morado mill is now consistently running at this rate, representing a 43% increase over the preceding six months. In the month of January 2025, the Campo Morado mill processed over 62,850 tonnes of ore; and ample built-in capacity at the mill remains towards future production growth.  With 2,000 tpd achieved, the next phase of optimization efforts will now focus on improving throughput to 2,400 tpd over the coming months.

Tahuehueto
Commissioning of this new gold mine has been progressing extremely well and is nearing completion. Throughput at the Tahuehueto mill has started to stabilize at the 1,000 tpd level. In the month of January 2025, even with a planned shutdown of greater than one week (consisting of testing and commiserate adjustments), the mill processed over 24,700 tonnes of ore; an exciting milestone for Luca. In preparation for commercial production, the Company is working to ensure sufficient parts and commodity supply redundancy is in place for its operations through purchasing and stocking a new warehouse now under construction on site.

Dan Barnholden, CEO, commented, "I am very pleased to see that our careful planning is allowing us to meet these important throughput objectives. Steady and stable operations with back up contingencies are key to consistent results. I would like to congratulate our entire Luca team and affiliates on a job well done. We've been able to quickly increase production at both operations and we can clearly see a path forward for further increases ahead."
