Vancouver, B.C., August 28, 2025: Luca Mining Corp. (“Luca” or the “Company”) (TSX-V: LUCA; OTCQX:

acquire a 100% interest in a large mining concession adjacent to the Company’s Tahuehueto Mine in
Durango, Mexico.
As consideration for a 100% interest in the Humaya 3 mining concession, which covers 2,507 hectares and
directly surrounds the Tahuehueto Mine, Luca has paid Fresnillo a cash purchase price of US$400,000. The

Dan Barnholden, Luca’s CEO , comment ed: “Acquiring th is strategic mining concession, which directly
surrounds our Tahuehueto Mine, aligns with our growth strategy as we add value to our assets. Luca will
continue to demonstrate our ability to increase shareholder value through our commitment to
2
exploration and discovery programs. This ground will play a key role in our near-term exploration strategy
at Tahuehueto as we expand our exploration efforts.”
Paul D. Gray, VP of Exploration, added: "The Humaya 3 mining concession surrounds the Tahuehueto Mine
and with this acquisition we have significantly increased both the size and exploration potential of our
mineral tenure at Tahuehueto. Known veins hosting our current mineral resources are interpreted
geologically to extend along strike both to the northeast and the southwest onto this newly acquired
concession. In particular, the Santiago vein, which hosts Mineral Resources and Reserves at the mine and
is the focus of our current surface drilling program, extends to the northeast directly onto this ground and
represents a high-priority drill target.”
